Kühlvorrichtung für heißes Schüttgut Die vorliegende Erfindung betrifft eine Kühlvorrichtung für heißes Schüttgut. Hot Bulk Cooling Device The present invention relates to a hot bulk cooling device.
Beim Kühlen von heißem Schüttgut - beispielsweise gesintertem Eisenerz - ist man bestrebt, die dabei entstehende Abwärme möglichst effizient auszunutzen. When cooling hot bulk material - for example, sintered iron ore - it is endeavored to exploit the resulting waste heat as efficiently as possible.
Stand der Technik sind Kreuzstromkühler in Form von Ringabsenkkühlern oder Ringabstreifkühlern . Bei Ringabsenkkühlern ist jedoch die Abwärmenutzung auf das erste Drittel des Küh- lers beschränkt, da die Ablufttemperatur ständig abnimmt. Bei Ringabstreifkühlern entsteht ein Gemisch aus heißer und warmer Abluft, dessen Temperatur grundsätzlich nicht so hoch wie maximal möglich ist, so dass ebenfalls die Effizienz der Ab¬ wärmenutzung verschlechtert ist. The prior art are cross-flow coolers in the form of Ringabsenkkühlern or Ringabstreifkühlern. However, with ring subsea coolers, the use of waste heat is restricted to the first third of the cooler, as the exhaust air temperature constantly decreases. In Ringabstreifkühlern results in a mixture of hot and warm exhaust air, the temperature is not as high as possible in principle, so that also the efficiency of Ab ¬ heat utilization is deteriorated.
Die Aufgabe der vorliegenden Erfindung besteht darin, Möglichkeiten zu schaffen, mittels derer die beim Kühlen von heißem Schüttgut entstehende Abwärme effizienter nutzbar ist. Die Aufgabe wird durch eine Kühlvorrichtung für heißes The object of the present invention is to provide possibilities by means of which the heat generated during the cooling of hot bulk waste heat can be used more efficiently. The task is done by a cooling device for hot
Schüttgut mit den Merkmalen des Anspruchs 1 gelöst. Vorteil¬ hafte Ausgestaltungen der erfindungsgemäßen Kühlvorrichtung sind Gegenstand der abhängigen Ansprüche 2 bis 9. Erfindungsgemäß ist vorgesehen, eine Kühlvorrichtung für heißes Schüttgut derart auszugestalten, Bulk material with the features of claim 1 solved. ¬ advantageous embodiments of the inventive cooling device are subject of the dependent claims 2 to 9. According to the invention to design a cooling apparatus for hot bulk material in such a way
- dass die Kühlvorrichtung einen Kühlturm mit einer vertikalen Hauptachse aufweist, in dem das heiße Schüttgut mittels eines Gasstroms gekühlt wird, - That the cooling device has a cooling tower with a vertical main axis, in which the hot bulk material is cooled by means of a gas stream,
- dass die Kühlvorrichtung eine Zuführeinrichtung aufweist, mittels derer das heiße Schüttgut von oben in den Kühlturm geschüttet wird, so dass das heiße Schüttgut im Kühlturm angehäuft wird, - dass die Kühlvorrichtung eine Entnahmeeinrichtung aufweist, mittels derer das Schüttgut im kalten Zustand unten aus dem Kühlturm entnommen wird, so dass das im Kühlturm verbleibende Schüttgut nach unten nachrutscht, - That the cooling device comprises a feeder, by means of which the hot bulk material is poured from above into the cooling tower, so that the hot bulk material is accumulated in the cooling tower, - That the cooling device has a removal device, by means of which the bulk material is removed in the cold state down from the cooling tower, so that the remaining material in the cooling tower slips down,
- dass die Kühlvorrichtung eine Gasfördereinrichtung aufweist, mittels derer der Gasstrom durch den Kühlturm gefördert wird, - That the cooling device comprises a gas conveying device by means of which the gas flow is conveyed through the cooling tower,
- dass die Kühlvorrichtung eine Abführeinrichtung aufweist, über die der Gasstrom aus dem Kühlturm abgeführt wird, - dass im Kühlturm eine Mehrzahl von Gasstromführungen angeordnet ist, die sich, ausgehend von in der Turmaußenwand angeordneten Einlassen, nach radial innen auf die Hauptachse zu erstrecken, - That the cooling device has a discharge device, via which the gas stream is discharged from the cooling tower, - that in the cooling tower, a plurality of gas flow guides is arranged, which, starting from arranged in the tower outer wall inlets to extend radially inward on the main axis,
- dass die Gasstromführungen als langgestreckte Führungen ausgebildet sind, die über ihre in ihrer jeweiligen Erstre- ckungsrichtung gesehene Länge Auslässe für den Gasstrom aufweisen, so dass der Gasstrom in das im Kühlturm befindliche heiße Schüttgut geleitet wird, - That the gas flow guides are formed as elongated guides, which have over their seen in their respective direction of extension Ausrich length for the gas flow, so that the gas stream is passed into the hot bulk material located in the cooling tower,
- dass die Gasstromführungen in Richtung der Hauptachse gese- hen im Mittelbereich des Kühlturms angeordnet sind und die - That the gas flow guides are arranged in the direction of the main axis seen in the central region of the cooling tower and the
Abführeinrichtung im oberen Bereich des Kühlturms angeordnet ist, so dass der Gasstrom das im Kühlturm befindliche heiße Schüttgut von unten nach oben durchströmt. Durch diese Ausgestaltung wird erreicht, dass der Gasstrom das heiße Schüttgut nicht im Kreuzstrom, sondern im Gegenstrom durchströmt. Ein Vermischen von heißer und warmer Abluft ist nicht mehr möglich. Vorzugsweise ist vorgesehen, dass die Gasstromführungen mit der Horizontalen einen Neigungswinkel bilden, so dass die Gasstromführungen auf die Hauptachse zu ansteigen. Durch diese Ausgestaltung kann der Wirkungsgrad beim Ausnutzen der Abwärme noch weiter optimiert werden. Dies gilt ganz besonders, wenn der Neigungswinkel derart gewählt ist, dass er in etwa dem Schüttgutwinkel entspricht, den das heiße Schüttgut mit der Horizontalen bildet. Der Neigungswinkel liegt daher vorzugsweise zwischen 20° und 45°, meist zwischen 25° und 35°. Vorzugsweise ist vorgesehen, dass die Auslässe ausschließlich auf der Unterseite der Gasstromführungen angeordnet sind. Durch diese Ausgestaltung wird erreicht, dass die Gefahr ei¬ ner Verstopfung der Auslässe minimiert oder sogar ganz vermieden wird. Abführeinrichtung is disposed in the upper region of the cooling tower, so that the gas stream flows through the hot bulk material located in the cooling tower from bottom to top. By this configuration it is achieved that the gas flow does not flow through the hot bulk material in a crossflow, but in countercurrent. Mixing hot and warm air is no longer possible. It is preferably provided that the gas flow guides form an angle of inclination with the horizontal, so that the gas flow guides increase toward the main axis. With this configuration, the efficiency in exploiting the waste heat can be further optimized. This is especially true when the angle of inclination is chosen so that it corresponds approximately to the bulk material angle that forms the hot bulk material with the horizontal. The angle of inclination is therefore preferably between 20 ° and 45 °, usually between 25 ° and 35 °. It is preferably provided that the outlets are arranged exclusively on the underside of the gas flow guides. This configuration ensures that the risk ei ¬ ner blockage of the outlets is minimized or even avoided altogether.
Eine Anordnung der Auslässe ausschließlich auf der Unterseite der Gasstromführungen kann beispielsweise dadurch erreicht werden, dass die Gasstromführungen jeweils zwei Seitenberei¬ che und einen die Seitenbereiche überbrückenden Dachbereich aufweisen, dass die Seitenbereiche im Wesentlichen vertikal verlaufen und dass der Dachbereich im Querschnitt die Form eines invertierten „V" aufweist. An arrangement of the outlets exclusively on the underside of the gas stream guides may for example be achieved in that the gas flow guides each comprise two side preparation ¬ surface and the side portions bridging the roof area, that the side portions extend substantially vertically and that the roof area in cross-section the shape of an inverted " V "has.
Vorzugsweise erstrecken sich die Gasstromführungen bis zur Hauptachse oder bis zu einer auf der Hauptachse angeordneten Nabe. Dadurch wird erreicht, dass das heiße Schüttgut prak¬ tisch im gesamten Querschnitt des Kühlturms von dem Gasstrom durchströmt und gekühlt wird. Preferably, the gas flow guides extend to the main axis or up to a arranged on the main axis hub. It is thereby achieved that the hot bulk material is practically ¬ table flows through the entire cross section of the cooling tower from the gas stream and cooled.
Vorzugsweise ist die Abführeinrichtung in der Turmaußenwan angeordnet. Durch diese Ausgestaltung wird erreicht, dass Zuführeinrichtung ohne Rücksicht auf die Ausgestaltung der Abführeinrichtung ausgelegt werden kann. Preferably, the discharge device is arranged in the Turmaußenwan. By this configuration it is achieved that feeding device can be designed without regard to the design of the discharge device.
In einer bevorzugten Ausgestaltung der vorliegenden Erfindung ist die Zuführeinrichtung als Drehschurre ausgebildet. Durch diese Ausgestaltung wird eine bessere Verteilung des heißen Schüttguts über die Querschnittfläche des Kühlturms erreicht. In a preferred embodiment of the present invention, the feed device is designed as a rotary chute. This embodiment achieves a better distribution of the hot bulk material over the cross-sectional area of the cooling tower.
Vorzugsweise ist vorgesehen, It is preferably provided
- dass der Kühlturm in einem Gebäude angeordnet ist, dessen Seitenwände sich, ausgehend von unten, bis über die Einläs- se erstrecken, that the cooling tower is arranged in a building whose side walls extend from below to above the inlet,
- dass die Entnahmeeinrichtung innerhalb des Gebäudes ange¬ ordnet ist, so dass das aus dem Kühlturm entnommene Schütt¬ gut sich zunächst innerhalb des Gebäudes befindet, - dass die Kühlvorrichtung eine Endlosfördereinrichtung aufweist, mittels derer das aus dem Kühlturm entnommene - that the removal means is attached ¬ arranged inside the building, so that the extracted from the cooling tower bulk ¬ initially is well within the building, - That the cooling device comprises an endless conveyor, by means of which the removed from the cooling tower

Diese Ausgestaltung ist insbesondere dann von Vorteil, wenn die Gasfördereinrichtung als Gebläse ausgebildet ist. Durch sie wird erreicht, dass Leckageverluste des Gasstroms mini¬ miert werden. This embodiment is particularly advantageous when the gas conveyor is designed as a fan. Through them it is achieved that leakage losses of the gas flow are mini ¬ mized.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit den Zeichnungen. Es zeigen in Prinzipdarstellung: FIG 1 eine Kühlvorrichtung für heißes Schüttgut, Further advantages and details emerge from the following description of an embodiment in conjunction with the drawings. FIG. 1 shows a cooling device for hot bulk material, FIG.
FIG 2 eine Gasstromführung im Querschnitt, 2 shows a gas flow guide in cross section,
FIG 3 eine Endlosfördereinrichtung von der Seite und 3 shows an endless conveyor from the side and
FIG 4 einen Durchtrittsbereich mit einem wannenförmigen 4 shows a passage area with a trough-shaped
Behälter im Querschnitt. Container in cross section.
Gemäß FIG 1 weist eine Kühlvorrichtung zum Kühlen von heißem Schüttgut 1 (beispielsweise kleinen Kügelchen von gesintertem Eisenerz) einen Kühlturm 2 mit einer vertikalen Hauptachse 3 auf. In dem Kühlturm 2 wird das heiße Schüttgut 1 mittels ei- nes Gasstroms 4 gekühlt. According to FIG. 1, a cooling device for cooling hot bulk material 1 (for example, small beads of sintered iron ore) has a cooling tower 2 with a vertical main axis 3. In the cooling tower 2, the hot bulk material 1 is cooled by means of a gas flow 4.
Die Kühlvorrichtung weist eine Zuführeinrichtung 5 auf. Mittels der Zuführeinrichtung 5 wird das heiße Schüttgut 1 von oben in den Kühlturm 2 geschüttet. Das heiße Schüttgut 1 wird dadurch im Kühlturm 2 angehäuft. The cooling device has a feed device 5. By means of the feeder 5, the hot bulk material 1 of poured into the top of the cooling tower 2. The hot bulk material 1 is thereby accumulated in the cooling tower 2.
Die Zuführeinrichtung 5 kann entsprechend der Darstellung von FIG 1 beispielsweise als Drehschurre ausgebildet sein, die mit einer vorbestimmten Drehzahl n rotiert wird. Die Drehzahl n ist in der Regel relativ klein. Beispielsweise kann die Drehzahl n im Falle der Ausgestaltung der Zuführeinrichtung 5 als Drehschurre im Bereich zwischen 0,25 Umdrehungen/Minute und einer Umdrehung/Minute liegen. The feeder 5 may be formed, for example, as a rotary chute according to the illustration of FIG 1, which is rotated at a predetermined speed n. The speed n is usually relatively small. For example, the speed n in the case of the embodiment of the feed device 5 as a rotary chute in the range between 0.25 revolutions / minute and one revolution / minute.
Durch die Ausbildung als Drehschurre wird das heiße Schüttgut 1 besser über den (horizontalen) Querschnitt des Kühlturms 2 verteilt. Ein wirksamer Radius r, mit dem die Zuführeinrich- tung 5 das heiße Schüttgut 1 verteilt, ist jedoch in der Re¬ gel erheblich kleiner als der Radius R des Kühlturms 2. Ins¬ besondere beträgt der wirksame Radius r, mit dem die Zuführ¬ einrichtung 5 das heiße Schüttgut 1 verteilt, in der Regel maximal 30 % des Radius R des Kühlturms 2. Meist werden sogar nur Zahlenwerte erreicht, die zwischen 10 % und 25 % liegen. In der Nähe der Turmaußenwand 6 (d. h. der vertikalen bzw. im Wesentlichen vertikalen Wand des Kühlturms 2) bildet sich daher ein Schüttungskegel aus. Der Schüttungskegel weist einen typischen Schüttgutwinkel auf. Der Schüttgutwinkel liegt - je nach Schüttgut 1 - in der Regel zwischen ca. 30° und ca. 38° . By training as a rotary chute, the hot bulk material 1 is better distributed over the (horizontal) cross-section of the cooling tower 2. An effective radius r with which the Zuführeinrich- tung 5, the hot bulk material 1 spread, but is considerably smaller than the radius R of the cooling tower in the re ¬ gel 2nd ins ¬ special is the effective radius r with which the feed device ¬ 5 distributes the hot bulk material 1, usually a maximum of 30% of the radius R of the cooling tower 2. Usually only numerical values are reached, which are between 10% and 25%. In the vicinity of the tower outer wall 6 (ie, the vertical or substantially vertical wall of the cooling tower 2), therefore, a discharge cone is formed. The cone has a typical bulk material angle. The bulk material angle is - depending on the bulk material 1 - usually between about 30 ° and about 38 °.
Die Kühlvorrichtung weist weiterhin eine EntnahmeeinrichtungThe cooling device furthermore has a removal device
7 auf. Mittels der Entnahmeeinrichtung 7 wird das Schüttgut 1 unten aus dem Kühlturm 2 entnommen. Dadurch rutscht das im7 on. By means of the removal device 7, the bulk material 1 is taken down from the cooling tower 2. This slips in the
Kühlturm 2 verbleibende Schüttgut 1 nach unten nach. Die Ent¬ nahmeeinrichtung 7 kann beispielsweise als Schubtisch ausgebildet sein, der sich kreisförmig bewegt. Die Kühlvorrichtung weist weiterhin eine GasfördereinrichtungCooling tower 2 remaining bulk material 1 down to. The Ent ¬ receiving device 7 may for example be designed as a push table, which moves in a circle. The cooling device furthermore has a gas delivery device
8 auf. Mittels der Gasfördereinrichtung 8 wird der Gasstrom 4 durch den Kühlturm 2 gefördert. Die Gasfördereinrichtung 8 ist vorzugsweise als Gebläse ausgebildet. Prinzipiell ist je¬ doch auch eine Saugvorrichtung möglich. 8 on. By means of the gas delivery device 8, the gas stream 4 is conveyed through the cooling tower 2. The gas conveying device 8 is preferably designed as a fan. In principle, a suction device is ever ¬ but possible.
Die Kühlvorrichtung weist weiterhin eine Abführeinrichtung 9 auf. Über die Abführeinrichtung 9 wird der Gasstrom 4 aus dem Kühlturm 2 abgeführt. The cooling device furthermore has a discharge device 9. Via the discharge device 9, the gas stream 4 is discharged from the cooling tower 2.
Wenn das Schüttgut 1 dem Kühlturm 2 zugeführt wird, ist es heiß. Typische Temperaturen liegen bei bis zu 900 °C. Wenn das Schüttgut 1 aus dem Kühlturm 2 entnommen wird, ist esWhen the bulk material 1 is supplied to the cooling tower 2, it is hot. Typical temperatures are up to 900 ° C. When the bulk material 1 is removed from the cooling tower 2, it is
(relativ) kalt. Typische Temperaturen liegen zwischen 70 °C und 150 °C. Das Abkühlen des heißen Schüttguts 1 erfolgt im Wesentlichen mittels des durch den Kühlturm 2 geförderten Gasstroms 4. Demzufolge wird der Gasstrom 4 im kalten Zustand (Temperatur typisch gleich Umgebungstemperatur) in den Kühlturm 2 geleitet und im heißen Zustand (Temperaturen typisch zwischen 600 °C und 800 °C) aus dem Kühlturm 2 abgeführt. (relatively) cold. Typical temperatures are between 70 ° C and 150 ° C. The cooling of the hot bulk material 1 takes place essentially by means of the conveyed through the cooling tower 2 gas stream 4. Accordingly, the gas stream 4 in the cold state (temperature typically equal to ambient temperature) in the cooling tower 2 passed and hot (temperatures typically between 600 ° C and 800 ° C) discharged from the cooling tower 2.
Der Kühlturm 2 ist in der Regel in einem Gebäude 10 angeord- net. Das Gebäude 10 weist Seitenwände 11 auf. Die Seitenwände 11 erstrecken sich, ausgehend von unten, bis zu einer Zwischenhöhe h des Kühlturms 2. Die Zwischenhöhe h liegt, bezo¬ gen auf die gesamte Höhe H des Kühlturms 2, in der Regel zwi¬ schen 40 % und 60 % der gesamten Höhe H des Kühlturms 2. The cooling tower 2 is usually arranged in a building 10. The building 10 has side walls 11. The side walls 11 extend, starting from the bottom, up to an intermediate height h of the cooling tower 2. The intermediate height h, bezo ¬ gene on the entire height H of the cooling tower 2, Zvi ¬ rule as a rule 40% and 60% of the total amount H of the cooling tower 2.
Die Gasfördereinrichtung 8 kann - insbesondere, wenn sie als Gebläse ausgebildet ist - innerhalb des Gebäudes 10 angeord¬ net sein. In der Regel ist die Gasfördereinrichtung 8 jedoch außerhalb des Gebäudes 10 angeordnet. Die Abführeinrichtung 9 ist im oberen Bereich des Kühlturms 2 angeordnet und damit außerhalb des Gebäudes 10. The gas delivery device 8 can - in particular, if it is designed as a fan - be angeord ¬ net within the building 10. As a rule, however, the gas delivery device 8 is arranged outside the building 10. The discharge device 9 is arranged in the upper region of the cooling tower 2 and thus outside of the building 10.
Die Abführeinrichtung 9 kann auf der Oberseite 12 des Kühlturms 2 angeordnet sein. Vorzugsweise ist die Abführeinrich- tung 9 in der Turmaußenwand 6 angeordnet, also seitlich. The discharge device 9 can be arranged on the upper side 12 of the cooling tower 2. Preferably, the discharge device 9 is arranged in the tower outer wall 6, that is to say laterally.
Im Kühlturm 2 ist eine Mehrzahl von Gasstromführungen 13 angeordnet. Prinzipiell beträgt die Minimalanzahl an Gasstrom- führungen 13 zwei. In der Praxis sind jedoch mindestens sechs Gasstromführungen 13 vorhanden. Die Maximalzahl an Gasstromführungen 13 ist prinzipiell nicht begrenzt. In der Regel werden jedoch Zahlenwerte von 40 nicht überschritten. Meist beträgt die Anzahl an Gasstromführungen 13 zwischen 8 und 16. In the cooling tower 2, a plurality of gas flow guides 13 is arranged. In principle, the minimum number of gas flow 13 two. In practice, however, at least six gas flow guides 13 are present. The maximum number of gas flow guides 13 is not limited in principle. In general, however, numerical values of 40 are not exceeded. In most cases, the number of gas flow guides 13 is between 8 and 16.
Die Gasstromführungen 13 sind gemäß FIG 1 als langgestreckte Führungen ausgebildet. Sie weisen Einlässe 14 auf, die in der Turmaußenwand 6 angeordnet sind. Ausgehend von den Einlässen 14, erstrecken sich die Gasstromführungen 13 nach radial innen auf die Hauptachse 3 des Kühlturms 2 zu. Der Verlauf der Gasstromführungen 13 kann beispielsweise speichenartig (dar¬ gestellt) , sichelförmig usw. sein. Auch andere Verläufe sind möglich. Es kommt nur darauf an, dass der Abstand zur Haupt- achse 3 des Kühlturms 2 entlang der Längserstreckung der Gasstromführungen abnimmt. The gas flow guides 13 are formed as shown in FIG 1 as elongated guides. They have inlets 14 which are arranged in the tower outer wall 6. Starting from the inlets 14, the gas flow guides 13 extend radially inward towards the main axis 3 of the cooling tower 2. The course of the gas flow passages 13, for example, spoke-like manner, be crescent-shaped, etc. (dar provided ¬). Other courses are possible. It is only important that the distance to the main axis 3 of the cooling tower 2 along the longitudinal extent of the gas flow guides decreases.
Die Gasstromführungen 13 weisen - über ihre in ihrer jeweiligen Erstreckungsrichtung gesehene Länge - Auslässe 15 für den Gasstrom 4 auf. Der - zu diesem Zeitpunkt noch kalte - Gas¬ strom 4 wird daher über die Einlässe 14 in die Gasstromführungen 13 eingeleitet und von dort über die Auslässe 15 in das im Kühlturm 2 befindliche heiße Schüttgut geleitet. Der Querschnitt der Gasstromführungen 13 kann über ihre Länge gesehen konstant sein. Vorzugsweise verringert sich der Quer¬ schnitt der Gasstromführungen 13 jedoch entsprechend der Darstellung von FIG 1 auf die Hauptachse 3 des Kühlturms 2 zu. Die Gasstromführungen 13 sind in Richtung der Hauptachse 3 des Kühlturms 2 gesehen im Mittelbereich 16 des Kühlturms 2 angeordnet. Der Mittelbereich 16 erstreckt sich von ca. 30 % der gesamten Höhe H des Kühlturms 2 bis ca. 70 % der gesamten Höhe H des Kühlturms 2. Unabhängig von der genauen Anordnung der Gasstromführungen 13 sind jedoch die Gasstromführungen 13 unterhalb der Abführeinrichtung 9 angeordnet. Wenn der Kühlturm 2 in dem Gebäude 10 angeordnet ist, sind die Einlässe 14 weiterhin unterhalb des Dachs 17 des Gebäudes 10 angeordnet. Die Seitenwände 11 des Gebäudes 10 erstrecken sich daher bis über die Einlässe 14 der Gasstromführungen 13. Auf Grund der Anordnung der Gasstromführungen 13 unterhalb der Abführeinrichtung 9 durchströmt der Gasstrom 4 das im Kühlturm 2 be- findliche heiße Schüttgut 1 von unten nach oben (Gegenstromprinzip) . The gas flow guides 13 have - over their seen in their respective extension direction length - outlets 15 for the gas stream 4. The - at this time still cold - gas ¬ stream 4 is therefore introduced via the inlets 14 in the gas flow guides 13 and passed from there via the outlets 15 in the cooling tower 2 located in the hot bulk material. The cross section of the gas flow guides 13 can be seen over its length constant. Preferably, the cross-section ¬ but reduces the gas flow passages 13 corresponding to the illustration of FIG 1 to the main axis 3 of the cooling tower 2 to. The gas flow guides 13 are arranged in the direction of the main axis 3 of the cooling tower 2 in the central region 16 of the cooling tower 2. The central region 16 extends from about 30% of the total height H of the cooling tower 2 to about 70% of the total height H of the cooling tower 2. Regardless of the exact arrangement of the gas flow guides 13, however, the gas flow guides 13 are arranged below the discharge device 9. When the cooling tower 2 is arranged in the building 10, the inlets 14 are further arranged below the roof 17 of the building 10. The side walls 11 of the building 10 therefore extend beyond the inlets 14 of the gas flow guides 13. Due to the arrangement of the gas flow guides 13 below the discharge device 9, the gas flow 4 flows through the hot bulk material 1 in the cooling tower 2 from bottom to top (countercurrent principle). ,
Die Gasstromführungen 13 können prinzipiell horizontal verlaufen. Vorzugsweise bilden die Gasstromführungen 13 jedoch entsprechend der Darstellung von FIG 1 mit der Horizontalen einen Neigungswinkel ß, so dass die Gasstromführungen 13 auf die Hauptachse 3 des Kühlturms 2 zu ansteigen. Der Neigungs¬ winkel ß kann nach Bedarf bestimmt sein. Vorzugsweise ist der Neigungswinkel ß so gewählt, dass er in etwa dem Schüttgut- winkel entspricht. Insbesondere sollte der Neigungswinkel ß zwischen 20° und 45° liegen. Besonders bevorzugt sind Werte zwischen 28° und 40°. The gas flow guides 13 can in principle run horizontally. However, the gas flow guides 13 preferably form an inclination angle β with the horizontal, as shown in FIG. 1, so that the gas flow guides 13 increase toward the main axis 3 of the cooling tower 2. The tilt angle can ¬ ß be determined as needed. The angle of inclination β is preferably selected such that it approximately corresponds to the bulk material angle. In particular, the inclination angle β should be between 20 ° and 45 °. Particular preference is given to values between 28 ° and 40 °.
Prinzipiell ist es möglich, die Auslässe 15 in den Gasstrom- führungen 13 an beliebiger Stelle vorzusehen. Bevorzugt ist jedoch, dass die Auslässe 15 entsprechend der Darstellung von FIG 2 ausschließlich auf der Unterseite der Gasstromführungen 13 angeordnet sind. Insbesondere können die Gasstromführungen 13, wie in FIG 2 dargestellt, auf ihrer gesamten Unterseite offen sein. In diesem Fall weisen die Gasstromführungen 13 vorzugsweise jeweils zwei Seitenbereiche 18 und einen Dachbe¬ reich 19 auf. Die Seitenbereiche 18 verlaufen im Wesentlichen vertikal. Der Dachbereich 19 überbrückt die Seitenbereiche 18. Er weist vorzugsweise im Querschnitt die Form eines in- vertierten „V" auf. In principle, it is possible to provide the outlets 15 in the gas flow guides 13 at any desired location. However, it is preferred that the outlets 15 are arranged exclusively on the underside of the gas flow guides 13, as shown in FIG. In particular, the gas flow guides 13, as shown in FIG 2, be open on its entire underside. In this case, the gas stream guides 13 preferably each have two side portions 18 and a Dachbe on ¬ rich 19th The side areas 18 are substantially vertical. The roof area 19 bridges over the side areas 18. It preferably has the shape of an inverted "V" in cross section.
Es ist möglich, dass die Gasstromführungen 13 vor der Hauptachse 3 des Kühlturms 2 enden. Vorzugsweise erstrecken sich die Gasstromführungen 13 jedoch bis zur Hauptachse 3 (bzw. bis zu einer im Bereich der Hauptachse 3 des Kühlturms 2 an¬ geordneten „Nabe" 20). Wenn der Kühlturm 2 innerhalb des Gebäudes 10 angeordnet ist, ist in der Regel auch die Entnahmeeinrichtung 7 innerhalb des Gebäudes 10 angeordnet. Das aus dem Kühltürm 2 entnommene Schüttgut 1 befindet sich daher zunächst (noch) innerhalb des Gebäudes 10. Die Kühlvorrichtung weist daher in diesem Fall eine Einrichtung auf, mittels derer das aus dem Kühlturm 2 entnommene Schüttgut 1 aus dem Gebäude 10 abgeführt wird. Diese Einrichtung ist gemäß FIG 3 vorzugsweise als Endlosför¬ dereinrichtung 21 ausgebildet. It is possible that the gas flow guides 13 end in front of the main axis 3 of the cooling tower 2. Preferably, the gas flow passages 13, however, extend to the main axis 3 (or up to the region of the main axis 3 of the cooling tower 2 at ¬ parent "hub" 20). If the cooling tower 2 is arranged within the building 10, the removal device 7 is usually arranged within the building 10 as well. The removed from the cooling tower 2 bulk material 1 is therefore initially (still) within the building 10. The cooling device therefore has in this case a device by means of which the removed from the cooling tower 2 bulk material 1 is discharged from the building 10. This device is preferably designed according to FIG 3 as Endlosför ¬ dereinrichtung 21.
Insbesondere im Falle der Ausbildung der Gasfördereinrichtung 8 als Gebläse, wenn also der Gasstrom 4 zunächst in das Ge¬ bäude 10 geblasen wird und erst von dort aus über die Einläs- se 14 in die Gasstromführungen 13 eingeleitet wird, sollten Durchtrittsbereiche 22, in denen die Endlosfördereinrichtung 21 aus dem Gebäude 10 austritt und wieder in das Gebäude 10 eintritt, relativ dicht sein. Zu diesem Zweck ist gemäß FIG 3 vorgesehen, dass die Endlosfördereinrichtung 21 wannenartige Behälter 23 aufweist. Die Behälter 23 weisen quer zur Förder- richtung x gesehen gemäß FIG 4 einen Behälterquerschnitt auf. In Förderrichtung x gesehen weisen sie gemäß FIG 3 eine Behälterlänge 1 auf. Beispielsweise kann die Endlosförderein¬ richtung 21 zu diesem Zweck als so genannter Wellkantgurt mit Querstollen ausgebildet sein. In particular, in the case of the formation of the gas delivery device 8 as a fan, that is, when the gas stream 4 is first blown into the Ge ¬ building 10 and only from there via the inlet 14 in the gas flow ducts 14 is introduced, passage areas 22, in which the Endless conveyor 21 exits the building 10 and enters the building 10 again, be relatively tight. For this purpose, it is provided according to FIG. 3 that the endless conveying device 21 has trough-like containers 23. As seen in FIG. 4, the containers 23 have a container cross section transversely to the conveying direction x. Viewed in the conveying direction x, they have a container length 1 according to FIG. For example, the Endlosförderein ¬ direction 21 may be formed for this purpose as a so-called Wellkantgurt with transverse studs.
Die Durchtrittsbereiche 22, durch die hindurch die Endlosför¬ dereinrichtung 21 (genauer: die Behälter 23) aus dem Gebäude 10 austreten und in das Gebäude 10 eintreten, sind vorzugs¬ weise als Tunnel ausgebildet. Die Tunnel 22 weisen einen Querschnitt auf, der gemäß FIG 4 an den Behälterquerschnitt angepasst ist. Gegebenenfalls können an den Seiten der Tun¬ nelwände Dichtungslippen oder dergleichen angeordnet sein. Die Tunnel 22 weisen weiterhin in Förderrichtung x gesehen jeweils eine Tunnellänge L auf, die größer als die Behälter- länge 1 ist. Vorzugsweise ist die Tunnellänge L sogar mindes¬ tens zweimal so groß wie die Behälterlänge 1, beispielsweise ca. 2,5-mal bis ca. 3,5-mal so groß. Die vorliegende Erfindung weist viele Vorteile auf. Insbeson¬ dere ist das Kühlen des heißen Schüttguts 1 im Kühlturm 2 mit einem überlegenen Wirkungsgrad möglich. Weiterhin weist die erfindungsgemäße Kühlvorrichtung nur wenige mechanische Bau¬ teile auf. Sie ist daher sowohl in der Anschaffung als auch in der Wartung günstiger als die Systeme des Standes der Technik. Darüber hinaus wird bei der vorliegenden Erfindung eine geringere Menge an Kühlluft benötigt als im Stand der Technik. Die Gasfördereinrichtung 8 kann daher kleiner dimensioniert sein als bei vergleichbaren Kühlvorrichtungen des Standes der Technik. Auch etwaige der Abführeinrichtung 9 nachgeordnete Reinigungs- und Entstaubungseinrichtungen können kleiner dimensioniert werden als im Stand der Technik. The passage regions 22, through which the Endlosför ¬ dereinrichtung 21 (more precisely, the container 23) exiting from the building 10 and enter the building 10 are, preferably ¬ designed as tunnels. The tunnels 22 have a cross-section which, according to FIG. 4, is adapted to the container cross-section. If necessary, can be arranged on the sides of doing ¬ nelwände sealing lips or the like. The tunnels 22 furthermore each have, in the conveying direction x, a tunnel length L which is greater than the length of the container 1. Preferably, the tunnel length L is even Minim ¬ least twice as large as the length of the container 1, for example about 2.5 times to about 3.5 times as large. The present invention has many advantages. Insbeson ¬ particular is the cooling of hot bulk material 1 in the cooling tower 2 with a superior efficiency possible. Furthermore, the cooling device according to the invention has only a few mechanical components . It is therefore cheaper to purchase and in terms of maintenance than the systems of the prior art. Moreover, in the present invention, a smaller amount of cooling air is required than in the prior art. The gas delivery device 8 can therefore be smaller in size than in comparable cooling devices of the prior art. Also, any of the discharge device 9 downstream cleaning and dedusting devices can be dimensioned smaller than in the prior art.
Die obige Beschreibung dient ausschließlich der Erläuterung der vorliegenden Erfindung. Der Schutzumfang der vorliegenden Erfindung soll hingegen ausschließlich durch die beigefügten Ansprüche bestimmt sein. The above description is only for explanation of the present invention. The scope of the present invention, however, is intended to be determined solely by the appended claims.
