Description

Technical Field

[0001] The present invention belongs to the field of dust removal spray towers, and particularly relates to a dust removal spray tower for an adjustable explosion-proof spray system. Background Art

[0002] A dust removal spray tower is a wet dust removal device widely used in industrial waste gas treatment. Its working principle is to transport the absorption liquid (usually water or chemical solution) to the spray system in the tower through a circulation pump to form atomized droplets that come into reverse contact with the dust-containing gas, and use the droplets to capture, dissolve, or chemically react to remove dust and harmful substances.

[0003] Currently, when treating dust-containing gas, it is a common practice to set two groups of spray mechanisms in the spray tower to achieve staged spraying, which can improve the dust removal efficiency to a certain extent. However, this method has significant defects. The nozzles in the spray tower are fixedly installed, and the spray angle and coverage area cannot be adjusted. When treating high-concentration dust-containing gas, it is difficult for the absorption liquid to fully cover the flowing area. It is difficult to efficiently purify only relying on the existing spray mode. To improve this situation, it is often necessary for the circulation pump to provide a greater pressure to make the absorption liquid contact more dust under the limited spray mode. If the existing circulation pump cannot meet the pressure requirement, a larger power circulation pump needs to be replaced, which increases the operating cost; secondly, in order to improve the treatment effect of dust-containing gas with a higher concentration, a spray mechanism is usually added inside the spray tower to further achieve multi-stage spraying of the dust-containing gas, but this causes the circulation pump to need to provide a greater pressure further, making higher requirements for the circulation pump and further increasing the operating cost.

Specific embodiments

[0032] The following will further elaborate on this application Figure 1 - Figure 11 in conjunction with the appended drawings.

[0033] Please refer to Figure 1 and Figure 2 , a dust removal spray tower for an adjustable explosion-proof spray system, comprising a tower body 1. Inside the tower body 1, two groups of spraying mechanisms 2 are sequentially arranged from bottom to top. Inside the tower body 1, two groups of packing layers 3 are fixedly arranged, and each group of packing layer 3 is located directly below the corresponding spraying mechanism 2.

[0034] Referring to Figure 1 and Figure 2 , an air inlet pipe 12 for introducing dust-containing gas into the interior of the tower body 1 is connected and arranged at the lower right end of the tower body 1. An exhaust pipe 13 for discharging the treated dust-containing gas is connected and arranged at the top of the tower body 1. A demister 14 is fixedly arranged at the upper end inside the tower body 1. The packing layer 3 includes a grid plate fixedly arranged inside the tower body 1, and multi-faceted hollow ball packings are stacked on the upper part of the grid plate.

[0035] When treating the dust-containing gas, the dust-containing gas enters the interior of the tower body 1 through the air inlet pipe 12, and then the cooperation of the spraying mechanism 2, the packing layer 3 and the demister 14 can be used to treat the dust-containing gas entering the interior of the tower body 1. The treated gas is finally discharged through the exhaust pipe 13.

[0036] Referring to Figure 1 , Figure 3 and Figure 10, the spraying mechanism 2 includes a main liquid guiding pipe 21 fixedly arranged inside the tower body 1, and a plurality of sub-liquid guiding pipes 22 arranged in a linear array are communicated on both the left and right sides of the main liquid guiding pipe 21. A liquid collecting tank 10 is communicated with the lower end of the outer side of the tower body 1, and a liquid supply mechanism 11 for supplying liquid to the main liquid guiding pipe 21 is arranged on the liquid collecting tank 10. The liquid supply mechanism 11 includes a pump body 111 fixedly arranged on the upper part of the liquid collecting tank 10. The water inlet end of the pump body 111 is communicated with a water inlet pipe 112, and the bottom end of the water inlet pipe 112 penetrates into the inside of the liquid collecting tank 10. The water outlet end of the pump body 111 is communicated with a three-way pipe 113. The other two ends of the three-way pipe 113 far away from the pump body 111 are respectively communicated with the corresponding main liquid guiding pipes 21. A filter screen 114 is fixedly arranged inside the liquid collecting tank 10, and the water inlet pipe 112 is located on the right side of the filter screen 114.

[0037] Refer to Figure 3 and Figure 5 , the spraying mechanism 2 further includes two groups of spraying components one 23 arranged on the main liquid guiding pipe 21 and the sub-liquid guiding pipes 22. Each group of spraying components one 23 includes a plurality of spraying pipes 231 distributed along a circular track. The two circular tracks are concentric circles. The spraying pipes 231 are located at the intersections of the circular track and the main liquid guiding pipe 21 and the sub-liquid guiding pipes 22, and the plurality of spraying pipes 231 are communicated with the corresponding main liquid guiding pipe 21 or sub-liquid guiding pipe 22. A spraying pipe 231 communicated with the main liquid guiding pipe 21 is arranged at the center of the concentric circles (as Figure 11 shown), and a main spray head 232 is communicated with the bottom of the spraying pipe 231.

[0038] After the dust-containing gas enters the inside of the tower body 1, the pump body 111 works to pump the absorption liquid inside the liquid collecting tank 10 into the three-way pipe 113 through the water inlet pipe 112, and then pumps the absorption liquid into the inside of the main liquid guiding pipe 21 and the sub-liquid guiding pipes 22 through the three-way pipe 113. Then, after the absorption liquid enters the spraying pipes 231, it will be sprayed out through the main spray heads 232. The sprayed absorption liquid cooperates with the packing layer 3 to perform dust removal work on the dust-containing gas. The absorption liquid after treating the dust-containing gas will fall to the bottom end inside the tower body 1 and enter the inside of the liquid collecting tank 10, and then can be recycled after being filtered by the filter screen 114.

[0039] Refer to Figure 3 and Figure 5 , a spraying component two 24 for expanding the spraying range in cooperation with the spraying pipe 231 is arranged on the outer side of the spraying pipe 231. The spraying component two 24 includes a liquid guiding ring 241 rotatably arranged on the outer side of the spraying pipe 231. Two branch pipes 242 are arranged on the outer side of the liquid guiding ring 241, and a sub-spray head 243 is communicated with the bottom end of the branch pipe 242.

[0040] Refer to Figure 5 、 Figure 7 and Figure 8, the branch pipe 242 located at the center of the inner circular track and the concentric circles is in an inverted L shape. Two water outlets 6 communicating with the liquid guide ring 241 are arranged on the outer side of the spray pipe 231 at the liquid guide ring 241. The branch pipe 242 is threadedly connected to the liquid guide ring 241, and an electronic valve 7 is fixedly installed on the branch pipe 242. The heights of two adjacent branch pipes 242 in the vertical direction are different, and the angles of the branch pipes 242 on the main liquid guide pipe 21 and the branch pipes 242 on the auxiliary liquid guide pipe 22 are also different (as Figure 5 and Figure 11 shown).

[0041] In order to improve the dust removal effect on the dust-containing gas with a relatively high concentration, when the dust-containing gas with a relatively high concentration enters the interior of the tower body 1, the electronic valve 7 on the branch pipe 242 can be opened when the absorption liquid enters the interior of the spray pipe 231. Then, part of the absorption liquid inside the spray pipe 231 will enter the liquid guide ring 241 through the water outlet 6, and then the absorption liquid enters the branch pipe 242 from the liquid guide ring 241 and is sprayed out through the auxiliary spray head 243. Thus, the absorption liquid sprayed out by the auxiliary spray head 243 and the absorption liquid sprayed out by the main spray head 232 form different liquid flow trajectories inside the tower body 1, which can fill the blind area of the spray of the main spray head 232, fully cover the space through which the dust-containing gas flows, greatly increase the contact probability between the absorption liquid and the dust-containing gas, and further improve the dust removal effect, so that there is no need to replace the pump body 111, reducing the operation cost.

[0042] At the same time, since the heights of two adjacent branch pipes 242 in the vertical direction are different, and the angles of the branch pipes 242 on the main liquid guide pipe 21 and the branch pipes 242 on the auxiliary liquid guide pipe 22 are also different, the absorption liquid sprayed out by the auxiliary spray head 243 and the absorption liquid sprayed out by the main spray head 232 are distributed in a staggered manner in the vertical space. The absorption liquid at different heights will form multiple cross-contacts with the rising dust-containing gas during the descending process, thereby increasing the contact times and time between the dust-containing gas and the absorption liquid, and further strengthening the treatment effect on the dust-containing gas. Without adding a spray mechanism 2, the operation cost is further reduced.

[0043] Refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 9, a rotating ring 8 is fixedly arranged on the upper part of the liquid guiding ring 241, and a gear 9 is fixedly arranged on the outer side of the rotating ring 8. On the rear side of the tower body 1, two adjusting components 4 for rotationally adjusting the second spraying component 24 are further arranged. The adjusting component 4 includes a reciprocating cylinder 41 fixedly arranged on the outer side of the tower body 1. The telescopic end of the reciprocating cylinder 41 is located inside the tower body 1 and is fixedly provided with an arc-shaped plate 42. A plurality of connecting rods 43 distributed along the arc direction are fixedly arranged at the bottom of the arc-shaped plate 42. A transmission tooth plate 44 is fixedly arranged at the bottom of the connecting rod 43. A rack 45 is fixedly arranged at a position of the transmission tooth plate 44 opposite to the corresponding gear 9, and the rack 45 is engaged with the corresponding gear 9.

[0044] In order to further improve the spraying range of the absorption liquid, during the process of treating the dust-containing gas, the reciprocating cylinder 41 works to push the arc-shaped plate 42 to reciprocate left and right inside the tower body 1. The movement of the arc-shaped plate 42 can drive the rack 45 on the transmission tooth plate 44 to reciprocate left and right through the connecting rod 43. The reciprocating left and right movement of the rack 45 can drive the rotating ring 8 to reciprocally rotate through the gear 9, so as to drive the auxiliary nozzle 243 to reciprocally rotate around the main nozzle 232. Thus, the trajectory of the absorption liquid sprayed from the auxiliary nozzle 243 changes accordingly. Compared with the original fixed spraying area, under the rotation of the auxiliary nozzle 243, it begins to continuously sweep across the internal space of the tower body 1 in a fan shape, thereby further improving the spraying range of the absorption liquid, and then the absorption liquid can contact the dust-containing gas more comprehensively and frequently.

[0045] Refer to Figure 3 , Figure 4 and Figure 7 , a supporting member 5 for assisting in supporting the adjusting component 4 is arranged on the first spraying component 23. The supporting member 5 includes a connecting ring 51 fixedly arranged on the outer side of the spray pipe 231. Two supporting rods 52 are fixedly arranged on the outer side of the connecting ring 51. A plurality of ball grooves are formed in the upper part of the supporting rod 52. A ball is rotatably arranged in the ball groove, and the side of the ball away from the ball groove is in rolling contact with the bottom of the transmission tooth plate 44.

[0046] In order to maintain the stability of the transmission tooth plate 44 during the movement, when the transmission tooth plate 44 reciprocates left and right, it will be in rolling contact with the balls on the supporting rod 52. At this time, the transmission tooth plate 44 can be stably supported by the supporting rod 52, which can prevent the transmission tooth plate 44 from sagging and deforming due to gravity. At the same time, the use of the balls enables the transmission tooth plate 44 to reciprocate more smoothly, thus ensuring the stability of the rotation of the rotating ring 8.

[0047] Refer to Figure 5 and Figure 9, the branch pipe 242 located on the outer circular track includes a first connecting pipe 244, a second connecting pipe 245 and a corrugated pipe 246. The corrugated pipe 246 is communicatively arranged between the first connecting pipe 244 and the second connecting pipe 245, and the bottom end of the second connecting pipe 245 is communicatively connected to the secondary spray head 243. Fixed rings 247 are fixedly arranged on the outer sides of both the first connecting pipe 244 and the second connecting pipe 245. A spring 248 is fixedly arranged between the two fixed rings 247, and the corrugated pipe 246 is located inside the return spring 248. Two guide rods 249 are fixedly arranged on the fixed ring 247 on the second connecting pipe 245, and one end of the guide rod 249 slidably passes through the fixed ring 247 on the first connecting pipe 244. A roller 250 is fixedly arranged on the side of the second connecting pipe 245 away from the corresponding fixed ring 247.

[0048] In order to ensure that the branch pipe 242 on the outer circular track is not affected by the inner wall of the tower body 1 during rotation, when the branch pipe 242 on the outer circular track approaches the inner wall of the tower body 1 during the rotation process, the roller 250 will contact and roll on the inner wall of the tower body 1. At this time, the second connecting pipe 245 will be squeezed. With the cooperation of the spring 248, the guide rod 249 and the fixed ring 247, it can move stably for a certain distance. Then when the branch pipe 242 moves away from the inner wall of the tower body 1, the spring 248 is used to reset the branch pipe 242, which ensures the continuity of the rotation of the branch pipe 242 on the outer circular track and further ensures that the secondary spray head 243 can continuously and stably spray and treat the dust-containing gas around the inner wall of the tower body 1.

[0049] During specific operation, when treating the dust-containing gas, the dust-containing gas enters the interior of the tower body 1 through the intake pipe 12. Then, with the cooperation of the liquid supply mechanism 11, the spraying mechanism 2, the packing layer 3 and the demister 14, the dust-containing gas entering the interior of the tower body 1 can be treated, and the treated gas is finally discharged through the exhaust pipe 13.

[0050] When the interior of the tower body 1 enters a dust-containing gas with a relatively high concentration through the intake pipe 12, the electronic valve 7 on the branch pipe 242 is opened, so that the pump body 111 operates to pump the absorption liquid in the liquid collection tank 10 into the main spray head 232 and the secondary spray head 243. At this time, the absorption liquid sprayed by the secondary spray head 243 and the absorption liquid sprayed by the main spray head 232 form different liquid flow trajectories inside the tower body 1, which can fill the blind area of the main spray head 232's spraying, comprehensively cover the space through which the dust-containing gas flows, greatly increase the contact probability between the absorption liquid and the dust-containing gas, and thus improve the dust removal effect, making it unnecessary to replace the pump body 111.

[0051] Meanwhile, the absorption liquid sprayed by the secondary spray head 243 and the absorption liquid sprayed by the main spray head 232 form a staggered distribution in the vertical space. During the descent process, the absorption liquid at different heights will form multiple cross-contacts with the rising dust-containing gas, thereby increasing the contact times and duration between the dust-containing gas and the absorption liquid, and further enhancing the treatment effect on the dust-containing gas.

[0052] Moreover, when the branch pipe 242 on the outer circular track approaches the inner wall of the tower body 1 during rotation, the roller 250 will contact and roll on the inner wall of the tower body 1. At this time, the second connecting pipe 245 will be squeezed. Under the combined action of the spring 248, the guide rod 249 and the fixing ring 247, it can move stably for a certain distance. Then, when the branch pipe 242 moves away from the inner wall of the tower body 1, the spring 248 is used to reset the branch pipe 242, ensuring the continuity of the rotation of the branch pipe 242 on the outer circular track, and further ensuring that the secondary spray head 243 can continuously and stably spray and treat the dust-containing gas around the inner wall of the tower body 1.

[0053] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
