Abstract

This high-temp. (e.g., 1300 deg.C) pyrolysis reactor for melting industrial waste is a combination of already-known components. It provides environment-friendly and problem-free elimination of the waste (claimed). The fly-ash particles carried by the flue gas are blown into the reactor chamber, melted in the high-temp. zone, mixed with residual fluid slag, and granulated for use as a road-building material (claimed). Variants claimed include the return of hot flue gases into the reactor chamber for pre-drying of the pyrolysis material, so enabling temps. of 1300-1500 deg.C to be reached. USE/ADVANTAGE - Industrial waste, including poisonous waste from the pharmaceutical, chemical and plastics industries, can be destroyed without leaving harmful or inconvenient residues.

Description

Die vorliegende Erfindung "Hochtemperatur-Pyrolysereaktor zur Abfallschmelze" hat die Aufgabe, in einem umweltfreundlichen Ver­ fahren den Abfall sowie Industrierückstände einzuschmelzen. Die Umweltfreundlichkeit wird durch folgende Maßnahmen erreicht:The present invention "high temperature pyrolysis reactor for Waste melt "has the task in an environmentally friendly Ver drive the waste and industrial residues to melt. Environmental friendliness is achieved through the following measures:

  • 1. Es werden keine Rauchgase an die Umgebung abgegeben,1. No flue gases are released into the environment,
  • 2. Dioxine und Flurine werden im Hochtemperaturbereich thermisch zerlegt,2. Dioxins and Flurine become thermal in the high temperature range disassembled,
  • 3. die Schlacke wird verflüssigt durchmischt, granuliert und dann für den Straßen- und Wegebau verwendet,3. The slag is liquefied, mixed and then granulated used for road and path construction,
  • 4. die Rauchgase werden im Krisprozeß in den Reaktorraum zurück­ geführt und dienen zur Vortrocknung des Abfalls und die Flug­ asche wird eingeschmolzen.4. The flue gases are returned to the reactor chamber in the crisis process led and serve to pre-dry the waste and the flight ash is melted down.

Diese Aufgaben werden gemäß der Erfindung durch die Kombination von an sich bekannten Bauelementen gelöst. Die Zeichnung zeigt inThese objects are achieved according to the invention by the combination of known components solved. The drawing shows in

Fig. 1 im Mittelschnitt schematisch im verkleinerten Maßstab den Hochtemperaturreaktor. Fig. 1 in the middle section schematically on a reduced scale the high temperature reactor.

Auf einem starken Fundament 1 ist ein aus feuerfesten Steinen aufgebauter Reaktorraum 2, welcher außen mit einem etwa 10 mm starken Blechgehäuse 3 ummantelt ist. Oben ist eine Materialbeschic­ kungsschleuse 4, welche durch 2 Klappen 5 wechselseitig geöffnet und geschlossen werden kann. On a strong foundation 1 there is a reactor chamber 2 made of refractory bricks, which is encased on the outside with an approximately 10 mm thick sheet metal housing 3 . Above is a material feed lock 4 , which can be opened and closed alternately by two flaps 5 .

Der Polypgreifer 12 füllt Abfallmengen durch die Materialschleuse 5 in den Reaktorraum 2 ein. Aus dem Rauchgasdom 6 wird über die Leitung 10 das Rauchgas abgesaugt und vom Gebläse 8 über die Lüftung 9 mit Frischluft gemischt und in den Reaktorraum gedrückt. Ein Gasregler 11 mischt im genauen stöchiometrischen Verhältnis die Luftmassen. In einer hier nicht dargestellten Schaltwarte 12 werden die verschiedenen Temperaturen überwacht.The polyp gripper 12 fills waste quantities through the material lock 5 into the reactor space 2 . The flue gas is drawn off from the flue gas dome 6 via the line 10 and mixed with fresh air by the blower 8 via the ventilation 9 and pressed into the reactor space. A gas regulator 11 mixes the air masses in a precise stoichiometric ratio. The various temperatures are monitored in a control room 12 , not shown here.

Ein Galsölbrenner 13 dient zum Anfahren des Pyrolyseprozesses. Die heißen Rauchgase gelangen nicht ins Freie, sondern dienen zur Vortrocknung des im Reaktorraum liegenden Abfalls. Dadurch ist es möglich, so hohe Reaktortemperaturen von 1300 Grad zu erreichen. Die hohe Temperatur ergibt den Vorteil, daß alle chemischen Ver­ bindungen, wie Dioxine, Flurane, SO2, Stickoxide usw. thermisch zerlegt werden. Die Schlacke wird flüssig und läuft über einen Granu­ lator 15 ab. Die granulierte Schlacke wird für den Straßen- und Wege­ bau weiterverwendet. Auch die von den Rauchgasen mitgerissene Flug­ asche wird mit eingeblasenen und verflüssigt.A Galsölbrenner 13 is used to start the pyrolysis process. The hot flue gases do not escape to the outside, but serve to pre-dry the waste lying in the reactor room. This makes it possible to reach reactor temperatures as high as 1300 degrees. The high temperature gives the advantage that all chemical compounds such as dioxins, flurans, SO 2 , nitrogen oxides, etc. are thermally decomposed. The slag becomes liquid and runs over a granulator 15 . The granulated slag is used for road and path construction. The fly ash entrained by the flue gases is also blown in and liquefied.

Das Frischluftrelventil 7 regelt automatisch die stöchiome­ trisch richtige Beimischung von Frischluft.The fresh air valve 7 automatically controls the stoichiometrically correct admixture of fresh air.

In Weiterbildung der Erfindung zeigt Fig. 2 den Hochtemperatur- Pyrolysereaktor mit angebauter Entstickungsanlage 17.In a development of the invention, FIG. 2 shows the high-temperature pyrolysis reactor with an attached denitrification plant 17 .

Je nach Abfallart wird ein Teil der Rauchgase durch die Entstic­ kungsanlage geleitet und dort auf chemischen Wege von den verschiedenen Stickoxiden befreit und dann durch die Leitung 18 in den Reaktorraum zurückgepumpt.Depending on the type of waste, a part of the flue gases is passed through the Entstic kungsanlage and chemically freed from the various nitrogen oxides and then pumped back through line 18 into the reactor space.

Bei stark schwefelhaltigen Abfällen wird nach Fig. 3 ein sog. "Magnomhlejektor" hinzugeschaltet der der Dolomitstaub in den Py­ rolyseraum einbläst und somit im statur nacendi bei den hohen Tempera­ turen den Schwefel bindet und die Eisenmaterialabzerrungen verhindert.For high-sulfur waste 3 is a so-called. "Magnomhlejektor" switched in the dolomite dust in the Py rolyseraum blowing temperatures and thus in stature nacendi at the high temperature is shown in FIG. Binds the sulfur and prevent the Eisenmaterialabzerrungen.

Das CO2 und CO problem ist praktisch gelöst durch die Rück­ führung der Rauchgase in den heißen Reaktorraum. Bei 1300 bis 1500 Grad zerfallen diese Moleküle und der Kohlenstoff wird mit verbrannt.The CO 2 and CO problem is practically solved by the return of the flue gases to the hot reactor room. At 1300 to 1500 degrees these molecules disintegrate and the carbon is also burned.
