[0030] The following will be described in detail in combination with the accompanying Figures 1-11 The present application is further described in detail.

[0031] The embodiment of the present application discloses a synthetic leather production waste gas treatment device.

One side of the condensing device 3 is provided with an air pipe 5 in communication with the adsorbing device 4. The body 1 is provided with a PLC controller (not shown in the figure) for controlling the operation of the device, which is a prior art and will not be described here. When the exhaust gas enters the body 1 through the air inlet 2, it is first cooled and condensed by the condensing device 3, and then the condensed exhaust gas enters the adsorbing device 4 through the air pipe 5, and the harmful substances in the exhaust gas are deeply treated by the adsorbing device 4, effectively removing volatile organic compounds, odors, etc. Finally, the exhaust gas treated by the adsorbing device is transported to the next processing procedure until the exhaust gas meets the environmental protection emission standard.

[0033] Referring to Figure 2 , Figure 3 , the condensing device 3 comprises a condensing box 31 and a condensing pipe 32. The condensing box 31 is arranged at one side of the body 1, and the condensing pipe 32 is arranged at one side of the air inlet 2 and connected to the inner wall of the body 1. Both ends of the condensing pipe 32 are connected to the condensing box 31. The condensing box 31 is provided with a water storage tank connected to the condensing pipe 32, a condenser for condensing the liquid in the water storage tank, and a pump connected to the upper side of the water storage tank and connected to the condensing pipe 32. When the pump is running, the liquid in the water storage tank can circulate in the condensing pipe 32, ensuring the condensing effect of the condensing pipe 32 on the exhaust gas.

[0034] Referring to Figure 4 , Figure 5 and Figure 7 , the inner wall of one end of the air pipe 5 close to the condensing device 3 is provided with a filtering mechanism 51, which comprises a frame connected to the air pipe 5 and a filter element connected between the frames. The filter element can remove large particles in the exhaust gas and reduce the burden of the adsorbing device 4. The inner wall of the air pipe 5 is connected with a positioning member 52 for fixing the filtering mechanism 51. In this application, the positioning member 52 is a plug rod, and in other embodiments, the positioning member 52 can also be a buckle, a bolt, etc.

[0035] Referring to Figure 5 , Figure 7 and Figure 8The adsorption device 4 comprises a rotating shaft 41 rotatably connected to the inside of the body 1 and a plurality of activated carbon adsorption units 42 mounted on the outside of the rotating shaft 41. The activated carbon adsorption unit 42 comprises a shell 421 and a plurality of bending plates 422 fixedly connected to the inside of the shell 421, and activated carbon particles are filled between the plurality of bending plates 422. For the waste gas generated in the synthetic leather production process, the adsorption capacity of the granular activated carbon to volatile organic compounds (VOCs) is about 0.2-0.35 kg of organic gas per kg of activated carbon particles. Flow channels 423 for guiding the flow of waste gas are arranged between the plurality of bending plates 422.

[0036] The inner wall of the body 1 is provided with a waste gas passage 6 in communication with the flow channel 423 in one of the activated carbon adsorption units 42, and the waste gas passage 6 is in communication with the air pipe 5. The two ends of the shell 421 are fixedly connected with filter screens for covering the edges of the bending plates 422, which prevent the activated carbon particles from spilling during rotation of the device and ensure that the waste gas can stably enter the flow channel 423. The outer side of the rotating shaft 41 is fixedly connected with a plurality of partition plates 411, and the two sides of each partition plate 411 are fixedly connected with guide rails 412. The two sides of each shell 421 are provided with guide grooves 4211 for inserting the guide rails 412, which can ensure the stability of the connection between the plurality of activated carbon adsorption units 42 and the rotating shaft 41 and avoid mutual interference between the plurality of activated carbon adsorption units 42.

[0037] When the waste gas enters the flow channel 423 through the waste gas passage 6, the plurality of bending plates 422 can guide the flow between the waste gas and the activated carbon particles and increase the contact time between the waste gas and the activated carbon particles, thereby improving the adsorption effect of the waste gas.

[0038] When installing or dismounting the activated carbon adsorption unit 42, the guide grooves 4211 at the two ends of the shell 421 are aligned with the guide rails 412, and then the shell 421 is pushed to move until the guide rails 412 are completely inserted into the guide grooves 4211, at which time the shell 421 is fixed between the two partition plates 411, completing the installation of the activated carbon adsorption unit 42; the shell 421 is pulled or pushed to slide along the guide rails 412 until the guide grooves 4211 of the shell 421 are disengaged from the guide rails 412, completing the dismounting of the activated carbon adsorption unit 42.

[0039] Referring to Figure 5 , Figure 6 and Figure 9The inside of the body 1 is internally provided with a plurality of limiting mechanisms 7 for limiting the position of the partition plate 411. The limiting mechanism 7 comprises a plurality of telescopic rods 71 and a limiting strip 72 fixedly connected to the movable end of the telescopic rod 71. The inner wall of the body 1 is provided with a limiting groove 12 for accommodating the plurality of telescopic rods 71 and the limiting strip 72. The fixed end of the plurality of telescopic rods 71 is fixedly connected to the inner wall of the limiting groove 12, and the limiting strip 72 is slidingly connected to the inner wall of the limiting groove 12. The side of the partition plate 411 away from the rotating shaft 41 is provided with a positioning groove 4111 for inserting the limiting strip 72. The end of the limiting strip 72 close to the partition plate 411 is provided with a chamfer 721, and the side of the limiting strip 72 away from the chamfer 721 abuts against the inner wall of the limiting groove 12.

[0040] As the activated carbon particles continuously adsorb the gas in the waste gas, the weight of the activated carbon particles itself gradually increases. When the weight reaches a predetermined value, the partition plate 411 can drive the chamfer 721 of the limiting strip 72, so that the limiting strip 72 retracts to the inner wall of the limiting groove 12, and the return spring 73 contracts. Until the limiting strip 72 is separated from the positioning groove 4111, at this time, the rotating mechanism and the activated carbon adsorption unit 42 can rotate until another activated carbon adsorption unit 42 rotates into the waste gas passage 6. At this time, the limiting strip 72 is inserted into the positioning groove 4111 on the side of another partition plate 411 under the pushing of the return spring 73, and the automatic switching of the activated carbon adsorption unit 42 is completed.

[0041] Referring to Figure 9 , Figure 10 and Figure 11 , the inside of the body 1 is provided with a blocking piece 11 for preventing the partition plate 411 from rotating excessively. The blocking piece 11 comprises an electric push rod 111 and a blocking rod 112 fixedly connected to the movable rod of the electric push rod 111. The two ends of each partition plate 411 are provided with an opening groove 4112 for inserting the blocking rod 112. The two ends of the shell 421 are provided with a guide groove 4212 for guiding the blocking rod 112 to insert into the opening groove 4112. The inner wall of the body 1 is provided with a sliding groove 13 for sliding the blocking rod 112. The main body of the electric push rod 111 is fixedly connected to the inner wall of the body 1 and located on the inner side of the sliding groove 13.

[0042] When the rotating shaft 41 and the activated carbon adsorption unit 42 rotate, the electric push rod 111 is automatically controlled to operate by the PLC controller, and the blocking rod 112 is inserted into the guide groove 4212. With the continuous rotation of the rotating shaft 41 and the activated carbon adsorption unit 42, the blocking rod 112 is inserted into the opening groove 4112 at the two ends of the partition plate 411, preventing it from continuing to rotate, so that the new activated carbon adsorption unit 42 can stably communicate with the waste gas passage 6; when the limiting strip 72 is reinserted into the limiting groove 12, the electric push rod 111 is retracted to drive the blocking rod 112 to move away from the opening groove 4112 to the inner wall of the sliding groove 13.

[0043] With reference to Figure 3 , Figure 7 and Figure 8 , one side of the body 1 is provided with a discharging interval 8 for the active carbon adsorption unit 42. The inner side of the discharging interval 8 is provided with a discharging mechanism 9 for driving the active carbon adsorption unit 42 to separate from the partition plate 411. The discharging mechanism 9 includes a driving motor 91 fixedly connected to the lower end of the body 1, a threaded rod 92 fixedly connected to the output shaft of the driving motor 91, and a discharging plate 93 threadedly connected to the outer side of the threaded rod 92. The lower end of the body 1 is provided with a discharging groove 14 for the sliding of the discharging plate 93, and the end of the threaded rod 92 away from the driving motor 91 is rotationally connected to the inner wall of the discharging groove 14, and the rotation of the threaded rod 92 can drive the discharging plate 93 to move in the discharging groove 14. The positioning rod 94 is fixedly connected between the inner walls of the opposite sides of the discharging groove 14, and the inner wall of one end of the discharging plate 93 is slidingly connected to the outer wall of the positioning rod 94, and the positioning rod 94 is used to prevent the discharging plate 93 from being misaligned during movement.

[0044] When the active carbon adsorption unit 42 is saturated and enters the discharging interval 8, the driving motor 91 operates to drive the threaded rod 92 to rotate, thereby driving the discharging plate 93 to move in the discharging groove 14 until one side of the discharging plate 93 abuts against one side of the shell 421. With the continuous rotation of the threaded rod 92, the shell 421 is pushed to slide between the two partition plates 411 by the discharging plate 93, until the guide groove 4211 is separated from the guide rail 412, and the active carbon adsorption unit 42 is moved to one side of the body 1, completing the disassembly of the active carbon adsorption unit 42 for subsequent desorption treatment by the staff.

[0045] With reference to Figure 2 , Figure 3 , one side of the body 1 is provided with a discharging interval 8 for the active carbon adsorption unit 42. The inner side of the discharging interval 8 is provided with a discharging mechanism 9 for driving the active carbon adsorption unit 42 to separate from the partition plate 411. The discharging mechanism 9 includes a driving motor 91 fixedly connected to the lower end of the body 1, a threaded rod 92 fixedly connected to the output shaft of the driving motor 91, and a discharging plate 93 threadedly connected to the outer side of the threaded rod 92. The lower end of the body 1 is provided with a discharging groove 14 for the sliding of the discharging plate 93, and the end of the threaded rod 92 away from the driving motor 91 is rotationally connected to the inner wall of the discharging groove 14, and the rotation of the threaded rod 92 can drive the discharging plate 93 to move in the discharging groove 14. The positioning rod 94 is fixedly connected between the inner walls of the opposite sides of the discharging groove 14, and the inner wall of one end of the discharging plate 93 is slidingly connected to the outer wall of the positioning rod 94, and the positioning rod 94 is used to prevent the discharging plate 93 from being misaligned during movement.

[0046] The implementation principle of the synthetic leather production waste gas treatment device of the embodiment is: In the process of treating exhaust gas, when the exhaust gas enters the inside of the body 1 through the air inlet 2, it is first cooled and condensed by the condensing device 3, so that part of the harmful substances in the exhaust gas are condensed, then the condensed exhaust gas enters the adsorption device 4 through the air pipe 5, the filter mechanism 51 in the air pipe 5 removes large particle impurities in the exhaust gas, reducing the burden of the adsorption device 4; finally, the exhaust gas enters the flow channel 423 of the activated carbon adsorption unit 42, and is guided by the plurality of bending plates 422 to fully contact with the activated carbon particles, the activated carbon particles adsorb volatile organic compounds (VOCs) and harmful substances such as odors in the exhaust gas, and then the exhaust gas enters the next processing procedure through the exhaust gas passage 6.

[0047] When the activated carbon adsorption unit 42 is saturated, the increase in its weight can drive the partition plate 411 to push the chamfer 721 of the limiting strip 72, so that the limiting strip 72 is retracted into the limiting groove 12, and the return spring 73 is retracted; at this time, the rotating mechanism and the activated carbon adsorption unit 42 begin to rotate, and at the same time, the electric push rod 111 pushes the blocking rod 112 to insert into the guide groove 4212, with the continuous rotation of the rotating shaft 41 and the activated carbon adsorption unit 42, until the blocking rod 112 is inserted into the opening groove 4112 at both ends of the partition plate 411, blocking its continuous rotation, when the limiting strip 72 is reinserted into the limiting groove 12, the electric push rod 111 is retracted to drive the blocking rod 112 to disengage from the opening groove 4112, so that the new activated carbon adsorption unit 42 can be stably connected with the exhaust gas passage 6, and the switching of the activated carbon adsorption unit 42 is completed.

[0048] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
