Then it is filtered through the first filter screen, and finally the activated carbon plate in the exhaust pipe further adsorbs the residual harmful substances. The three-stage purification works together to ensure that the exhaust gas is thoroughly purified and meets the environmental emission standards. After spray absorption, the absorbent liquid carrying unreacted raw materials flows into the bottom of the treatment tank after being filtered through the first and second filters. It is then returned to the treatment tank for recycling through the return cylinder and return pipe, realizing the recovery and reuse of the absorbent liquid and unreacted raw materials. At the same time, the impurities intercepted by the first filter can be collected through the collection cylinder to avoid the waste of useful components, greatly improve the resource recycling rate, and reduce production costs. During the first filter screen filtration process, the vibration of the first filter screen can promptly shake off the impurities accumulated on the screen, preventing clogging; it eliminates the need for frequent shutdowns for cleaning, ensuring continuous and stable operation of the equipment and improving production efficiency.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: Figure 1-4As shown, this utility model provides a technical solution: a tail gas purification and recovery device for the synthesis process of alkylammonium modified bentonite thickener, including a treatment box 1. An air inlet 2 is welded through one end of the top of the treatment box 1. A rotating shaft 3 is rotatably connected to one end of the top of the treatment box 1. A rotating blade 4 is fixedly sleeved on the outer side of one end of the rotating shaft 3. Cams 5 are fixedly sleeved on both ends of the outer side of the rotating shaft 3. Spring telescopic columns 6 are installed on both sides of the top of the treatment box 1 by screws. An installation rod 7 is installed at the bottom of the spring telescopic column 6 by screws. The bottoms of the two installation rods 7 are connected by a first filter screen 8. The first filter screen 8 is inclined, and the outer side of the cam 5 is in contact with the end face of the mounting rod 7, which facilitates the reciprocating movement of the mounting rod 7, causing the first filter screen 8 to vibrate, and also facilitates the guidance of impurities, allowing the impurities to enter the collection cylinder 13.

[0019] The rotating blade 4 is located at one end of the air inlet 2, which facilitates driving the rotating blade 4 to rotate, thereby enabling the rotating shaft 3 to rotate.

[0020] A water pump 9 is fixedly connected to one end of the bottom of the treatment box 1. A water outlet pipe 10 is fixedly connected to the water outlet end of the water pump 9. A main water outlet pipe 11 is fixedly connected to one end of the top of the water outlet pipe 10. A nozzle 12 is threadedly connected to the bottom of the main water outlet pipe 11. The water outlet pipe 10 is fixedly installed inside the treatment box 1. A collection cylinder 13 is installed on one side of the treatment box 1 by screws. An air outlet cylinder 14 is installed on one end of the collection cylinder 13 by screws. An installation plate 15 is installed on the top of the air outlet cylinder 14 by screws. Activated carbon plates 16 are evenly installed on the bottom of the installation plate 15 by screws. A second filter screen 17 is installed at the bottom of the collection cylinder 13 by screws. A return cylinder 18 is installed at the bottom of the second filter screen 17 by screws. A return pipe 19 is fixedly connected to the bottom of the return cylinder 18. One end of the return pipe 19 is fixedly connected to one end of the processing box 1. A door 20 is hinged to one end of the processing box 1.

[0021] The activated carbon plate 16 is located inside the gas outlet 14 and outside one end of the first filter screen 8, which facilitates the collection of impurities and the purification of exhaust gas.

[0022] A rotating plate is hinged to one end of the bottom of the collecting cylinder 13. The bottom surface of the rotating plate is in contact with the top surface of the second filter screen 17, which facilitates the cleaning of impurities on the top surface of the second filter screen 17.

[0023] Open the door 20 of the treatment box 1, add sufficient tail gas absorption liquid into the treatment box 1, close the door 20, and introduce the tail gas generated during the synthesis of alkyl ammonium modified bentonite thickener into the treatment box 1 through the air inlet 2. Start the water pump 9, and the water pump 9 delivers the absorption liquid in the treatment box 1 to the main water outlet pipe 11 through the water outlet pipe 10. Then, the spray nozzle 12 at the bottom of the main water outlet pipe 11 sprays the liquid evenly into the treatment box 1 to form a spray area, so that the absorption liquid and the tail gas come into contact with each other. The volatile organic compounds and unreacted alkyl ammonium and other raw materials in the tail gas are adsorbed by the absorption liquid, and the purification is completed. The absorption liquid carries the adsorbed components and dust downwards. When the exhaust gas flows, it drives the rotating blade 4 to rotate. The rotation of the rotating blade 4 drives the rotating shaft 3 and the outer cam 5 to rotate synchronously. During the rotation of the cam 5, it pushes the mounting rod 7 to move downward, and the spring telescopic column 6 is compressed. After the cam 5 rotates away from the mounting rod 7, the mounting rod 7 moves upward under the reset action of the spring telescopic column 6, causing the first filter screen 8 to vibrate back and forth. When the exhaust gas combined with the absorbent passes through the inclined first filter screen 8, the dust and impurities are intercepted. The vibrating first filter screen 8 shakes off the dust, and the dust slides down the inclined surface of the first filter screen 8 into the collection cylinder 13.

[0024] Impurities and part of the absorbent entering the collection cylinder 13 are filtered through the second filter screen 17 to remove dust and impurities. The filtered absorbent flows into the return cylinder 18 and then back to the treatment box 1 through the return pipe 19, realizing the recycling of absorbent and the recovery of useful components. The exhaust gas absorbed by spraying enters the exhaust cylinder 14. The activated carbon plate 16 in the exhaust cylinder 14 adsorbs the trace harmful substances remaining in the exhaust gas, completing a second purification. The purified exhaust gas is discharged from the exhaust cylinder 14.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
