DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , a chemical waste gas collection and treatment equipment, including a base 1, and also including: a support rod 103 symmetrically connected to the base 1; a rotating shaft 201, rotatably connected to the support rod 103; a clamping disk 2, fixedly connected to the rotating shaft 201; a zeolite molecular sieve cartridge 5, arranged between the two clamping disks 2, a waste gas conveying component, connected to the rotating shaft 201, and used to convey the waste gas to be treated into the zeolite molecular sieve cartridge 5; an arc plate 4, fixedly connected to the base 1, and in contact with the outer wall of the zeolite molecular sieve cartridge 5, wherein a groove 401 is provided on the arc plate 4, a hollow cavity 403 is provided in the arc plate 4, a gas nozzle 402 connected to the hollow cavity 403 is fixedly installed in the groove 401, a booster pump 405 is fixedly installed on the base 1, and the output end of the booster pump 405 is fixedly connected to the hollow cavity 403 through a pipe 404; a driving part, arranged in the pipe 404, and used to drive the rotating shaft 201 to rotate.

[0025] The exhaust gas conveying component includes an exhaust gas pipe 302 . A connecting cavity 3 communicating with the inner cavity of the zeolite molecular sieve cylinder 5 is provided at the axis of the rotating shaft 201 . A rotating joint 301 is provided on the rotating shaft 201 . The exhaust gas pipe 302 is connected with the connecting cavity 3 via the rotating joint 301 .

[0026] The driving part includes an impeller 6 . The pipeline 404 is fixedly connected to the support rod 103 . The impeller 6 is fixedly mounted on one end of the rotating shaft 201 that passes through the pipeline 404 .

[0027] An activated carbon filter is also included, and the activated carbon filter is arranged at the input end of the booster pump 405.

[0028] When in use, the exhaust gas is transported into the zeolite molecular sieve cartridge 5 through the exhaust pipe 302 and the connecting cavity 3 in sequence, and then the exhaust gas passes through the zeolite molecular sieve cartridge 5. Since the zeolite molecular sieve cartridge 5 can adsorb molecules smaller than its pore size into the inside of the cavity, and exclude molecules larger than the pore size from its cavity, when the exhaust gas passes through the zeolite molecular sieve cartridge 5, it can further adsorb harmful substances in the exhaust gas, and the particulate impurities carried in the exhaust gas are filtered and blocked in the zeolite molecular sieve cartridge 5, thereby achieving the effect of purifying the gas, and then the purified gas passes through the cavity of the zeolite molecular sieve cartridge 5 and is discharged to the outside; then the booster pump 405 is started, and the booster pump 405 absorbs external gas and transports it into the hollow cavity 403 through the pipeline 404, and finally sprays it out through the air nozzle 402, thereby reversely cleaning the particulate impurities that block the cavity of the zeolite molecular sieve cartridge 5, thereby achieving the effect of dredging the cavity of the zeolite molecular sieve cartridge 5, preventing the cavity of the zeolite molecular sieve cartridge 5 from being blocked, and affecting the adsorption treatment of harmful substances in the exhaust gas;

[0029] At the same time, when the gas passes through the pipeline 404, the gas drives the rotating shaft 201 to rotate through the impeller 6, and the rotating shaft 201 drives the clamping plate 2 to drive the zeolite molecular sieve cylinder 5 to rotate synchronously, so that the rotating zeolite molecular sieve cylinder 5 can accelerate the contact with the exhaust gas, thereby accelerating the efficiency of filtering and purifying the exhaust gas. At the same time, the rotating zeolite molecular sieve cylinder 5 also helps the air nozzle 402 to comprehensively clean the particulate impurities that block the cavities of the zeolite molecular sieve cylinder 5.

[0030] It should be supplemented that the section of the pipeline 404 fixedly connected to the booster pump 405 and the section fixedly connected to the hollow cavity 403 are both made of stretchable and shrinkable hoses, so the pipeline 404 will not interfere with the movement of the clamping plate 2.

[0033] Embodiment 3:

[0035] When it is necessary to clean the particulate impurities remaining in the zeolite molecular sieve cylinder 5 after cleaning, start the motor 104, the motor 104 drives the bidirectional screw 101 to rotate, the bidirectional screw 101 drives the two support rods 103 to move synchronously in opposite directions, and at the same time the support rod 103 drives the clamping plate 2 to move synchronously, so that the clamping plate 2 is separated from the zeolite molecular sieve cylinder 5, and then the zeolite molecular sieve cylinder 5 can be removed from between the two clamping plates 2, so as to facilitate the cleaning of the particulate impurities remaining in the zeolite molecular sieve cylinder 5 after cleaning.
