Description

Technical Field

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

[0002] The dust removal spray tower is a wet dust removal equipment 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 circulating pump, forming atomized droplets that contact the dust-containing gas in reverse, and use the droplets to capture, dissolve or chemically react to remove dust and harmful substances.

[0003] At present, when treating dust-laden gas, it is common practice to set up two groups of spray mechanisms in the spray tower to achieve graded 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 range cannot be adjusted. When treating high-concentration dust-laden gas, it is difficult for the absorption liquid to fully cover the area through which it flows, and it is difficult to purify efficiently with the existing spray mode alone. To improve this situation, the circulating pump is often required to provide a higher pressure so that the absorption liquid can contact more dust under the limited spray mode. If the existing circulating pump cannot meet the pressure requirements, it is necessary to replace a higher-power circulating pump, which increases the operating cost; secondly, in order to improve the treatment effect of dust-laden gas with high concentration, a spray mechanism is usually added inside the spray tower to further realize multi-stage spraying of dust-laden gas, but it causes the circulating pump to provide a higher pressure, which makes the requirements for the circulating pump higher and further increases the operating cost.

[0032] The following is combined with Figure 1 - Fig.11 This application is further described in detail.

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

[0034] See also Figure 1 and Figure 2 The lower right end of the tower body 1 is connected to an air inlet pipe 12 for dust-containing gas to enter the tower body 1, the top of the tower body 1 is connected to an exhaust pipe 13 for the treated dust-containing gas to be discharged, and a demister 14 is fixedly installed at the upper end of the tower body 1. The packing layer 3 includes a grid plate fixedly installed inside the tower body 1, and a multi-faceted hollow ball packing is stacked on the upper part of the grid plate.

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

[0036] See also Figure 1 , Figure 3 and Fig.10The spray mechanism 2 includes a main liquid pipe 21 fixedly arranged inside the tower body 1, and a plurality of auxiliary liquid pipes 22 distributed in a linear array are connected to the left and right sides of the main liquid pipe 21. A liquid collecting box 10 is connected to 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 pipe 21 is arranged on the liquid collecting box 10. The liquid supply mechanism 11 includes a pump body 111 fixedly arranged on the upper part of the liquid collecting box 10, and a water inlet pipe 112 is connected to the water inlet end of the pump body 111, and the bottom end of the water inlet pipe 112 penetrates into the interior of the liquid collecting box 10, and a three-way pipe 113 is connected to the water outlet end of the pump body 111, and the other two ends of the three-way pipe 113 away from the pump body 111 are respectively connected to the corresponding main liquid pipe 21, and a filter screen 114 is fixedly arranged inside the liquid collecting box 10, and the water inlet pipe 112 is located on the right side of the filter screen 114.

[0037] See also Figure 3 and Figure 5 The spray mechanism 2 also includes two groups of spray components 23 arranged on the main liquid pipe 21 and the auxiliary liquid pipe 22. Each group of spray components 23 includes a plurality of spray pipes 231 distributed along a circular track. The two circular tracks are concentric circles. The spray pipes 231 are located at the intersection of the circular track and the main liquid pipe 21 and the auxiliary liquid pipe 22. The plurality of spray pipes 231 are connected to the corresponding main liquid pipe 21 or the auxiliary liquid pipe 22. The center of the concentric circle is provided with a spray pipe 231 connected to the main liquid pipe 21 (such as Fig.11 As shown in FIG. 1 ), the bottom of the spray pipe 231 is connected to a main spray head 232.

[0038] When the dust-laden gas enters the interior of the tower body 1, the pump body 111 works to pump the absorption liquid inside the liquid collecting box 10 into the tee pipe 113 through the water inlet pipe 112, and then the absorption liquid is pumped into the interior of the main liquid guiding pipe 21 and the auxiliary liquid guiding pipe 22 through the tee pipe 113. Then, the absorption liquid enters the spray pipe 231 and is sprayed out through the main nozzle 232. The sprayed absorption liquid cooperates with the packing layer 3 to remove dust from the dust-laden gas. The absorption liquid after treating the dust-laden gas will fall to the bottom end of the tower body 1 and enter the interior of the liquid collecting box 10, and then can be recycled after being filtered by the filter net 114.

[0039] See also Figure 3 and Figure 5 A spray assembly 24 is arranged on the outside of the spray pipe 231 to cooperate with it to expand the spray range. The spray assembly 24 includes a liquid guide ring 241 rotatably arranged on the outside of the spray pipe 231. Two branch pipes 242 are arranged on the outside of the liquid guide ring 241. The bottom end of the branch pipe 242 is connected to an auxiliary nozzle 243.

[0040] See also Figure 5 , Figure 7 and Figure 8The branch pipe 242 located at the center of the inner circular trajectory and the concentric circle is in an inverted L shape. The outer side of the spray pipe 231 is located at the liquid guide ring 241 and has two water outlets 6 connected to 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 two adjacent branch pipes 242 are at different heights in the vertical direction, and the angles of the branch pipe 242 on the main liquid guide pipe 21 and the branch pipe 242 on the auxiliary liquid guide pipe 22 are also different (such as Figure 5 and Fig.11 as shown).

[0041] In order to improve the dust removal effect on dust-containing gases with higher concentrations, when dust-containing gases with higher concentrations enter 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, and 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 then is sprayed out through the auxiliary nozzle 243, so that the absorption liquid sprayed by the auxiliary nozzle 243 and the absorption liquid sprayed by the main nozzle 232 form different liquid flow trajectories inside the tower body 1, which can fill the blind area of ​​the main nozzle 232 spray, and fully cover the space through which the dust-containing gas flows, greatly improving the contact probability between the absorption liquid and the dust-containing gas, thereby improving the dust removal effect, making it unnecessary to replace the pump body 111, and reducing the operating cost.

[0042] At the same time, since the two adjacent branch pipes 242 are at different heights in the vertical direction, and the angles of the branch pipe 242 on the main liquid guide pipe 21 and the branch pipe 242 on the auxiliary liquid guide pipe 22 are also different, the absorption liquid sprayed by the auxiliary nozzle 243 and the absorption liquid sprayed by the main nozzle 232 are staggered in the vertical space. The absorption liquids at different heights will form multiple cross contacts with the rising dust-containing gas during the descending process, thereby increasing the number and time of contact between the dust-containing gas and the absorption liquid, and further enhancing the treatment effect on the dust-containing gas. There is no need to add a spray mechanism 2, which further reduces the operating cost.

[0043] See also Figure 2 , Figure 4 , Figure 6 , Figure 7 and Fig. 9A rotating ring 8 is fixedly provided on the upper part of the liquid guide ring 241, and a gear 9 is fixedly provided on the outer side of the rotating ring 8. Two groups of adjusting components 4 for rotating and adjusting the spraying component 24 are also provided on the rear side of the tower body 1. The adjusting component 4 includes a reciprocating cylinder 41 fixedly provided 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 plate 42. A plurality of connecting rods 43 distributed along the arc direction are fixedly provided at the bottom of the arc plate 42. A transmission tooth plate 44 is fixedly provided at the bottom of the connecting rod 43. A rack 45 is fixedly provided at the position of the transmission tooth plate 44 opposite to the corresponding gear 9, and the rack 45 is meshed with the corresponding gear 9.

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

[0045] See also Figure 3 , Figure 4 and Figure 7 A supporting member 5 for auxiliary support of the adjustment member 4 is provided on the spray component 23. The supporting member 5 includes a connecting ring 51 fixedly arranged on the outside of the spray pipe 231. Two supporting rods 52 are fixedly arranged on the outside of the connecting ring 51. A plurality of ball grooves are opened on the upper part of the supporting rod 52. Balls are rolled in the ball grooves, and the side of the ball away from the ball groove is in rolling contact with the bottom of the transmission gear plate 44.

[0046] In order to maintain the stability of the transmission tooth plate 44 during movement, the transmission tooth plate 44 will roll in contact with the ball bearings on the supporting rod 52 when it moves back and forth. At this time, the supporting rod 52 can stably support the transmission tooth plate 44, which can prevent the transmission tooth plate 44 from falling and deforming due to gravity. At the same time, the ball bearings can enable the transmission tooth plate 44 to reciprocate more smoothly, thereby ensuring the stability of the rotating ring 8 during rotation.

[0047] See also Figure 5 and Fig. 9The branch pipe 242 located on the outer circular track includes a connecting pipe 1 244, a connecting pipe 245 and a bellows 246, and the bellows 246 is connected between the connecting pipe 1 244 and the connecting pipe 2 245, and the bottom end of the connecting pipe 2 245 is connected with the auxiliary nozzle 243. A fixing ring 247 is fixedly arranged on the outer side of the connecting pipe 1 244 and the connecting pipe 2 245, a spring 248 is fixedly arranged between the two fixing rings 247, and the bellows 246 is located on the inner side of the reset spring 248, and two guide rods 249 are fixedly arranged on the fixing ring 247 located on the connecting pipe 2 245, and one end of the guide rod 249 slides through the fixing ring 247 located on the connecting pipe 1 244, and a roller 250 is fixedly arranged on the side of the connecting pipe 2 245 away from the corresponding fixing ring 247.

[0048] In order to ensure that the branch pipe 242 on the outer circular trajectory is not affected by the inner wall of the tower body 1 during rotation, when the branch pipe 242 on the outer circular trajectory approaches the inner wall of the tower body 1 during rotation, the roller 250 will contact and roll with the inner wall of the tower body 1, and the connecting pipe 245 will be squeezed at this time. With the cooperation of the spring 248, the guide rod 249 and the fixing ring 247, the connecting pipe 245 can be stably moved a certain distance. Then, when the branch pipe 242 is away from the inner wall of the tower body 1, the spring 248 is used to reset the branch pipe 242, thereby ensuring the continuity of the rotation of the branch pipe 242 on the outer circular trajectory, and further ensuring that the auxiliary nozzle 243 can continuously and stably spray the dust-containing gas around the inner wall of the tower body 1.

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

[0050] When dust-containing gas with a high concentration enters the interior of the tower body 1 through the air inlet pipe 12, the electronic valve 7 on the branch pipe 242 is opened, so that the pump body 111 works to pump the absorption liquid in the liquid collecting tank 10 into the main nozzle 232 and the auxiliary nozzle 243. At this time, the absorption liquid sprayed by the auxiliary nozzle 243 and the absorption liquid sprayed by the main nozzle 232 form different liquid flow trajectories inside the tower body 1, which can fill the blind spot of the main nozzle 232 spray and fully cover the space through which the dust-containing gas flows, greatly improving the contact probability between the absorption liquid and the dust-containing gas, thereby improving the dust removal effect, so that there is no need to replace the pump body 111.

[0051] At the same time, the absorption liquid sprayed by the auxiliary nozzle 243 and the absorption liquid sprayed by the main nozzle 232 are staggered in the vertical space. The absorption liquids at different heights will form multiple cross contacts with the rising dust-containing gas during the descending process, thereby increasing the number and time of contact 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 trajectory approaches the inner wall of the tower body 1 during its rotation, the roller 250 will roll in contact with the inner wall of the tower body 1. At this time, the connecting pipe 245 will be squeezed, and with the cooperation 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 is away from the inner wall of the tower body 1, the spring 248 is used to reset the branch pipe 242, thereby ensuring the continuity of the rotation of the branch pipe 242 on the outer circular trajectory, and further ensuring that the auxiliary nozzle 243 can continuously and stably spray the dust-containing gas around the inner wall of the tower body 1.
