Definitions

  • Device for protecting fume intake into a scrubber, as well as cleaning facility comprising such a device
  • the present invention relates to a device for protecting fume intake into a scrubber. It also relates to a facility for wet cleaning exhaust fumes from an engine of a marine vessel, this facility comprising such a protection device.
  • the scrubbers operate with between 500 and 4000 m 3 /h of water, depending on the design, the required performance and the power of the engine; at the same time, a little fraction of water as small as several liters per hour of water being introduced into the duct for the fumes is not tolerable.
  • the existing protection devices are insufficient in light of the very, very small allowable water entry, in particular during the transitional operating periods of the scrubbers.
  • FIG 1 shows a very simplified view of a marine scrubber 1 in which exhaust fumes F from one or several diesel engines of a ship are introduced into the bottom of the scrubber 1 , while being allowed therein through a vertical duct 2, which passes through the bottom of the scrubber while being generally centered on the latter.
  • a distribution device 3 distributes water, for example by spraying, this water being, in figure 1 , shown in the form of a rain P, this depiction being only symbolic in that the water falls above all in the form of drops and not necessarily vertically.
  • the fumes F that circulate from bottom to top inside the scrubber 1 are purified by transfer of the sulfur dioxide that they contain into the water coming from the distribution device 3 and circulate, by gravity, from top to bottom inside the scrubber 1 , this water next being discharged from the bottom of the scrubber via an outlet 4, if applicable while being partially recycled to the distribution device 3 in a manner not shown in figure 1 .
  • a protection device 5 is arranged inside the scrubber 1 between the downstream mouth of the duct 2 and the distribution device 3, while being placed vertically above the downstream mouth of the duct 2: the protection device 5 allows the fumes F that leave the duct 2 to pass, while protecting this duct against the introduction of water.
  • the protection device 5 is shown in the form of a Chinese hat, but other arrangements are possible.
  • Various examples are proposed in WO 2014/128261 , WO 2017/198653 and EP 3,260,187.
  • the effectiveness of the latter can be substantially compromised due to two troublesome phenomena, particularly in the transitional operating periods of the scrubber 1.
  • the first phenomenon that can occur is that a small portion of the liquid film E1 remains, by capillarity, adhered to the lower rim of the protection device 5 and migrates toward the central axis of the scrubber 1 along the lower face of the protection device, until unsticking from this lower face vertically over the duct 2, in the form of drops E2 that can then enter, by gravity, inside the duct 2.
  • the second phenomenon that can occur is that, due to its small momentum, the liquid film E1 leaves the protection device 5 at the periphery of the upper face of the latter, while forming one or several thin water curtains E3 for which it is easy, for movements of fumes symbolized by the arrows T, to extract a fraction carried to the inside of the duct 2.
  • the aforementioned movements of fumes T can correspond to recirculation movements of the fumes F inside the scrubber 1 , or to convective movements of fumes that appear in the transitional operating periods of the scrubber.
  • the current embodiments of the protection device 5 are insufficient to completely prevent the entry of water in the duct 2, such a water entry being intolerable once it exceeds several liters per hour, or an infinitesimal part of the water brought in by the distribution device 3, typically less than 1 /50000 th of the quantity of water distributed by this device 3.
  • the aim of the present invention is to propose a higher performing protection device.
  • the invention relates to a device for protecting fume intake into a scrubber, as defined in claim 1.
  • the invention also relates to a facility for wet cleaning exhaust fumes from an engine of a marine vessel, as defined in claim 10. Owing to the invention, the water which, coming from the distribution device, reaches the upper face of the apical body of the protection device according to the invention, such as the rain water P of figure 1 , becomes concentrated in the bottom of each channel of the protection device, streaming over the lateral slopes of each channel up to the bottom edge of the channel.
  • the water is thus collected in the bottom of each of the channels and forms a stream that flows therein in thick streams, like at the bottom of the bed of a torrent, from the central region of the apical body to the periphery of the latter where the aforementioned thick streams leave, with a large momentum, the upper surface of the apical body at the respective ends of these channels.
  • the geometric specificities of the channels in particular their depth and their opening angle, are provided accordingly by one skilled in the art, so that the water that falls on the upper face of the apical body and that may have a flow rate of several hundred cubic meters per hour in a marine scrubber, is concentrated in the form of the aforementioned thick streams by the channels.
  • the rain water P reaches the apical body over its entire upper surface, the water is concentrated entirely in the bottom of the channels and leaves this apical body, in the form of the aforementioned thick streams, exclusively at the ends of the bottom edges of the channels, the accumulation of these ends representing only a small portion of the periphery of the apical body. Due to their thickness and their momentum, these streams of water leave the apical body of the protection device according to the invention as liquid jets with a high speed and going far, while remaining globally in thick streams, somewhat like water coming from a garden hose.
  • - figure 1 is a schematic view of a facility for treating fumes, which belongs to the prior art and has been described above;
  • - figure 2 is a perspective view of a protection device according to the invention;
  • FIG. 3 and 4 are elevation views along arrow III of figure 2 and arrow VI of figure 3, respectively;
  • FIG. 5 is a view similar to figure 3, respectively illustrating two embodiment options for the protection device according to the invention.
  • FIGs 2 to 4 show a protection device 10 making it possible to protect the intake of fumes into a scrubber.
  • the protection device 10 is provided to be used in the cleaning facility shown in figure 1 , in place of the protection device 5.
  • the protection device 10 is associated with the scrubber 1 and the distribution device 3, described in detail above, such that when this cleaning facility is operational, the protection device 10 and the distribution device 3 are installed inside the scrubber, the distribution device 3 being located above the protection device 10.
  • the inner diameter of this scrubber is usually at least two meters.
  • the protection device 10 includes an apical body 1 1 , which, when the protection device 10 is installed in the scrubber 1 , constitutes the uppermost part of this protection device.
  • the apical body 1 1 is placed vertically above the downstream mouth of the vertical duct 2 for the intake of fumes F into the scrubber 1 , so as to protect this duct against the introduction of water while allowing the fumes leaving the duct 2 to pass: to that end, the rain water P coming from the distribution device 3 falls under the effect of gravity onto an upper face 12 of the apical body 1 1 , while a lower face of the apical body 1 1 is vertically distant from a downstream mouth of the duct 2 such that the fumes F leaving the duct can pass between this downstream mouth and the lower face of the apical body 1 1 to rejoin the rest of the inside of the scrubber 1.
  • the vertical projection of the upper face 12 of the apical body 1 1 represents a significant fraction, around 40% or more, of the inner cross-section of the scrubber 1.
  • the apical body 1 1 defines a central axis Z-Z that traverses the upper face 12 of the apical body 1 1 in a central region 1 1 A of the latter.
  • the axis Z-Z extends vertically and is advantageously concentric with the duct 2.
  • the protection device 10 includes fastening means 13 making it possible to secure the protection device 10 fixedly to the inside of the scrubber 1.
  • these fastening means 13 include a flange suitable for being fixedly attached around the apex of the duct 2, and feet connecting the aforementioned flange to the apical body 1 1 .
  • the fastening means 13 can be considered for the fastening means 13, the latter not being limiting with respect to the invention.
  • each channel 14 extends lengthwise substantially rectilinearly, from the central region 1 1 A of the apical body 1 1 to a periphery 1 1 B of the apical body, the channels 14 being distributed around the central region 1 1 A.
  • each channel 14 extends lengthwise radially to the axis Z-Z, from an end that is close to the axis Z-Z to an opposite end located on the periphery 1 1 B of the apical body 1 1.
  • the shape and expanse of the central region 1 1 A of the apical body 1 1 from which the channels 1 1 extend are not limited to the example considered in the figures. Conversely, in all cases, the periphery 1 1 B of the apical body 1 1 is occupied completely by the channels 1 1 , this periphery 1 1 B thus being distributed into portions following one another around the apical body 1 1 , each of these portions being occupied by one of the channels 14, as clearly shown in figure 4.
  • the channels 14 are identical to one another and are provided in eight copies, as clearly shown in figure 4. This being the case, in a variant that is not shown, a larger or smaller number of channels 14 can be considered, an advantageous size being that six to eighteen channels 14 are provided, preferably six to twelve channels 14.
  • each channel 14 has, in cross-section, a triangular section whereof a first of the three apices is located vertically lower than the other two apices when the protective device 10 is installed in the scrubber 1.
  • each channel 14 has a triangular vertical section, with a tip oriented downwards.
  • the triangular shape of the cross-section of each channel 14 is present over the entire length of the channel, having noted that, in the exemplary embodiment considered here, it is advantageously provided that for each of the channels 14, this triangular section increases as one travels over the channel from the central region 1 1 A to the periphery 1 1 B of the apical body 1 1 .
  • the first apex of the triangular shape of the cross-section of each channel 14 defines a bottom edge 15 along this channel.
  • the other two apices of the triangular shape of this cross-section of each channel 14 each define a top edge 17 along the channel.
  • each of the top edges 17 is connected to the bottom edge 15 by a lateral slope of the channel.
  • the bottom edge 15 is located vertically lower than each of the top edges 17. The corresponding difference in vertical separation characterizes the depth of the channel 14, which, at any point along the length of the channel, can be measured vertically between the bottom edge 15 and the top edges 17.
  • each channel 14 increases as one flows through the channel from the central region 1 1 A to the periphery 1 1 B of the apical body 1 1 .
  • this depth at the periphery 1 1 B of the apical body 1 1 has a value labelled D: according to an advantageous sizing, this value D is at least 70 mm.
  • D is at least 70 mm.
  • each channel 14 has, at its apex located on the bottom edge 15 of this channel, an angle, which is denoted a in figure 3 and which characterizes the opening of the channel.
  • this angle a is between 30 and 120°, preferably between 60 and 90°.
  • the value of the angle a can be connected to the number of channels 14.
  • the respective bottom edges 15 of the channels 14 rest on a conical surface, which, when the protection device 10 is installed in the scrubber 1 , converges upwards and the apical angle of which is between 90 and 170°, preferably between 100 and 140°.
  • the aforementioned conical surface, on which the bottom edges 15 rest can be fictitious in that this conical surface does not constitute a material or physical continuity, but simply designates a geometric surface.
  • the aforementioned conical surface is substantially centered on the axis Z-Z.
  • each of the bottom edges 15 thus runs rectilinearly and inclined relative to the horizontal, from the central region 1 1 A to the periphery 1 1 B of the apical body 1 1 , having noted that these bottom edges 15 come together, without necessarily being concurrent, at the central region 1 1 A, while they intersect the periphery 1 1 B of the apical body 1 1 at respective ends 16 of these bottom edges, opposite the central region 1 1 A.
  • the respective ends 16 of the bottom edges 15 are located on a circle C16, as clearly visible in figure 4.
  • the diameter of this circle C16 is typically more than a meter.
  • this circle C16 is provided to be substantially concentric to the duct 2 and has a diameter strictly larger than the inner diameter of this duct 2 such that the apical body 1 1 sufficiently covers, projected vertically, the downstream mouth of the duct 2, without causing an excessive head loss for the fumes F leaving this duct. More specifically, the diameter of the circle C16 is advantageously between 1 .1 and 2 times the inner diameter of the duct 2, preferably between 1 .25 and 1.65 times the inner diameter of the duct 2. This being the case, and as clearly shown in figure 4, the vertical projection of the periphery 1 1 B of the apical body 1 1 is not necessarily circular, due to the embodiment specificities of the channels 14.
  • the protection device 10 When the protection device 10 is installed in the scrubber 1 and, inside the scrubber, the rain water P coming from the distribution device 3 reaches the upper face 12 of its apical body 1 1 , the water streams over the lateral slopes of each of the channels 14, from the top edges 17, to become concentrated in the bottom of each channel, along the bottom edge 15 of the latter.
  • the channels 14 collect all of the water on the upper face 12 of the apical body 1 1 of the protection device 10.
  • the incline of the bottom edges 15 causes the collected water to flow in the bottom of each channel 14, from the central region 1 1 A to the periphery 1 1 B of the apical body 1 1.
  • the protection device 10 occupies a substantial fraction of the inside of the scrubber, a similar fraction of the rain P reaches the upper surface 12 of the apical body 1 1 as described just above. Still in light of the implementation context of the invention, this means that the upper face 12 of the apical body 1 1 thus typically receives several hundred cubic meters of water per hour.
  • Figure 5 illustrates an optional development of the protection device 10 of figures 2 to 4.
  • the protection device 10 includes, at the base of its apical body 1 1 , a collar 18 fastened to the apical body 1 1 so as, when the protection device 10 is installed in the scrubber 1 , to be arranged below this apical body, while extending substantially vertically from the lower face of the apical body 1 1 over a height h of between 15 and 75 mm and while being located completely inside the vertical projection of the apical body 1 1 .
  • the collar 18 thus makes it possible to interfere with any flows of water coming from the apical body 1 1 , in order to loosen the latter, and it prevents any potential migration of water over the lower face of the apical body 1 1 .
  • the collar 18 is cylindrical, while having an outer diameter that is advantageously between 0.86 and 0.985 times the diameter of the circle C16.
  • Figure 6 illustrates another optional development of the protection device 10 of figures 2 to 4, this optional development further being able to be combined with the collar 18 of figure 5.
  • the protection device 10 of figure 6 includes a deflector 19 having a cone shape or a pyramid shape with four, six or eight sides, which, at its apex, is truncated and has a through opening having a diameter equivalent to at least 100 mm.
  • the aforementioned equivalent diameter is conventionally defined as the ratio between four times the surface of the through opening and the perimeter of the latter.
  • the cone or pyramid shape of the deflector 19 is substantially centered on the axis Z-Z.

  • the deflector 19 makes it possible to reduce the head loss caused by the protection device 10 on the fumes F leaving the duct 2.
  • the cross-section of the channels 14 may be only substantially triangular, as long as it defines, for each channel, a lower bottom edge, on which lateral slopes of the channel concentrate the water collected by this channel, and along which the water flows until reaching the periphery 1 1 B of the apical body 1 1 of the protection device 10 before leaving the latter.
  • the bottom and top edges can thus be more or less blunt.

Abstract

Ce dispositif de protection (10) est approprié pour être disposé à l'intérieur d'un épurateur et comprend un corps apical (11) qui, lorsque le dispositif de protection est installé dans l'épurateur, est placé au-dessus de l'embouchure aval d'un conduit vertical d'admission des fumées dans l'épurateur, de manière à protéger le conduit contre l'introduction d'eau tout en laissant passer les fumées sortant du conduit. Afin que ce dispositif de protection fonctionne particulièrement bien, une face supérieure (12) du corps apical est pourvue de canaux de collecte d'eau (14) qui s'étendent chacun dans le sens de la longueur à partir d'une région centrale (11 A) du corps apical, autour duquel les canaux sont répartis, à une périphérie (11 B) du corps apical, qui est complètement occupée par les canaux. Chaque canal a sur toute sa longueur une section sensiblement triangulaire et dont le sommet inférieur définit un bord inférieur (15) le long du canal. Les bords inférieurs respectifs des canaux reposent sur une surface conique qui converge vers le haut et dont l'angle apical est compris entre 90 et 170°.
