Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas spray towers, in particular to a waste gas spray tower device for waste gas treatment. Background Art

[0002] The spray tower in the waste gas treatment equipment is the core of waste gas absorption. During the absorption process, the waste gas enters from the bottom of the absorption tower, and contacts with the circulating absorbent of the atomized spray in the spray area in countercurrent and undergoes a chemical reaction. The toxic and harmful waste gas in the waste gas is absorbed, and the dust in the waste gas can also be removed.

[0003] However, at present, most of the exhaust gas in the spray tower enters the spray tower from one direction, and the exhaust gas always impacts one side of the interior of the spray tower, causing the exhaust gas to be more on one side and less on the other side inside the spray tower, thereby causing the problem of uneven exhaust gas distribution inside the spray tower, affecting the uniform contact between the subsequent exhaust gas and the spray liquid, and affecting the effect of exhaust gas treatment.

[0004] Therefore, a waste gas spray tower device for waste gas treatment is proposed. Utility Model Content

[0007] Preferably, the lower tower body and the upper tower body are both connected to the middle tower body.

[0008] Preferably, the outer diameter of the impeller is smaller than the inner diameter of the exhaust gas diversion cover.

[0009] Preferably, the cross section of the guide groove is an isosceles trapezoidal structure.

[0010] Preferably, the first through hole and the second through hole are connected, and the first through hole is perpendicular to the horizontal plane, and the second through hole is perpendicular to the inner side wall of the guide groove.

[0011] Preferably, the exhaust gas inlet pipe and the exhaust gas diversion cover are connected.

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0013] The thrust generated by the flow of exhaust gas causes the impeller to rotate, and the rotational force of the impeller is used to make the exhaust gas flow 360 degrees from the central position of the lower tower body to the inner side of the lower tower body, thereby maximizing the uniform distribution of exhaust gas inside the lower tower body and avoiding the problem of more exhaust gas on one side and less on the other side of the spray tower caused by the traditional exhaust gas intake method. The exhaust gas can be evenly guided upward through the gas flow equalization platform, further ensuring the uniform distribution of exhaust gas in the spray tower and improving the effect of exhaust gas treatment.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a waste gas spray tower device for waste gas treatment, such as Figure 1-4 As shown, it includes a lower tower body 1, the top of the lower tower body 1 is integrally formed with a middle tower body 2, the top of the middle tower body 2 is integrally formed with an upper tower body 3, the lower tower body 1 and the upper tower body 3 are both connected to the middle tower body 2, an exhaust gas intake pipe 4 is embedded in the outer wall of one side of the lower tower body 1, the bottom end of the exhaust gas intake pipe 4 is fixedly connected to the exhaust gas diversion cover 5 by bolts, the exhaust gas intake pipe 4 and the exhaust gas diversion cover 5 are connected, an exhaust gas flow outlet 6 is opened on the outer wall of one side of the exhaust gas diversion cover 5, and the bottom of the exhaust gas diversion cover 5 is fixedly connected to the exhaust gas diversion cover 5 by bolts. The cover plate 7 is rotatably connected to a rotating shaft 8 at the top center position of the cover plate 7, and an impeller 9 is welded to the top of the rotating shaft 8. A gas flow equalizing platform 10 is fixedly connected to the inner wall of one side of the middle tower body 2 by bolts. A first through hole 11 is provided on the top of the gas flow equalizing platform 10, and a guide groove 12 is provided at the bottom center position of the gas flow equalizing platform 10. A second through hole 13 is provided on the inner top of the guide groove 12. A spray pipe 14 is embedded in the outer wall of one side of the upper tower body 3, and an atomizing nozzle is provided on the outer wall of one side of the spray pipe 14.

[0022] It should be noted that since most of the exhaust gas in the existing spray tower enters the spray tower from one direction, the exhaust gas has been impacting one side of the interior of the spray tower, causing the exhaust gas to be more on one side inside the spray tower and less on the other side, thereby causing the problem of uneven exhaust gas distribution inside the spray tower, affecting the subsequent uniform contact between the exhaust gas and the spray liquid, and affecting the effect of exhaust gas treatment. In this embodiment, the thrust generated by the exhaust gas flow causes the impeller 9 to rotate, and the rotational force of the impeller 9 is used to make the exhaust gas flow 360 degrees at the central position inside the lower tower body 1 toward the inner side of the lower tower body 1, thereby maximizing the uniform distribution of exhaust gas inside the lower tower body 1, avoiding the problem of more on one side inside the spray tower and less on the other side caused by traditional exhaust gas intake methods, and the exhaust gas can be evenly diverted upward through the gas equalizing platform 10, further ensuring the uniform distribution of exhaust gas in the spray tower and improving the effect of exhaust gas treatment.

[0023] Specifically, in this embodiment, this solution mainly includes an exhaust gas diversion cover 5 and a gas flow equalization platform 10. When in use, the exhaust gas enters the exhaust gas diversion cover 5 through the exhaust gas inlet pipe 4 after being pressurized and accelerated, and the exhaust gas is blown vertically to the impeller 9. The impeller 9 is pushed by the exhaust gas flow to rotate the shaft 8 on the cover plate 7, thereby causing the impeller 9 to rotate synchronously. During the rotation process, the impeller 9 guides the exhaust gas evenly to the surroundings, and the exhaust gas flows out of the exhaust gas diversion cover 5 through the exhaust gas flow outlet 6. The exhaust gas is inside the lower tower body 1. The exhaust gas flows 360 degrees toward the inner side of the lower tower body 1 at the central position of the lower tower body, maximizing the uniform distribution of the exhaust gas inside the lower tower body 1. During the upward flow of the exhaust gas, it enters the guide groove 12 at the bottom of the gas equalizing platform 10, and the exhaust gas flows along the internal top of the guide groove 12. During the process of moving obliquely upward, the exhaust gas enters the second through hole 13 and finally enters the upper tower body 3 through the first through hole 11. The spray pipe 14 sprays the spray liquid downward inside the upper tower body 3, and the spray liquid contacts the exhaust gas to achieve exhaust gas treatment.

[0024] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer diameter of the impeller 9 is smaller than the inner diameter of the exhaust gas splitter bell 5 .

[0025] In this embodiment, the impeller 9 can be made to rotate inside the exhaust gas diverter cover 5, so that the impeller 9 can evenly throw out the exhaust gas in a 360-degree direction.

[0026] In a further preferred embodiment of the present invention, Figure 4 As shown, the cross section of the guide groove 12 is an isosceles trapezoidal structure, the first through hole 11 and the second through hole 13 are connected, and the first through hole 11 is perpendicular to the horizontal plane, and the second through hole 13 is perpendicular to the inner wall of the guide groove 12.

[0027] In this embodiment, the trapezoidal guide groove 12 allows the exhaust gas to flow upward along the inner sidewall of the guide groove 12 and enter the second through hole 13 and the first through hole 11 in sequence.
