This can easily lead to insufficient adsorption-desorption effect or waste of adsorption-desorption tanks during the process. In addition, some gases may carry dust particles into the device when they enter, which can affect the performance of the adsorption-desorption tanks.

[0021] The diversion assembly 4 includes a main exhaust pipe 401, several diversion valves 402, and several first connecting pipes 403. The main exhaust pipe 401 is installed at the top of several auxiliary exhaust pipes 302. The several diversion valves 402 are respectively installed inside the main exhaust pipe 401 at positions between each pair of adjacent adsorption tanks 301. The diversion valves 402 can be three-way valves, etc., so that after the gas enters from one side, it can flow to different positions according to the opening and closing of the diversion valves 402. The several first connecting pipes 403 are respectively installed at the bottom of each diversion valve 402, and the other end of the first connecting pipe 403 is connected to an adjacent adsorption tank 301. (Refer to Appendix) Figure 1 As shown in the diagram, the bottom end of the first connecting pipe 403 is connected to an adsorption tank 301 on its right side, so that the gas that needs to be further processed can enter the new adsorption tank 301 for processing.

[0022] The filter cartridge 202 has a filter chamber 204 inside. The top of the filter chamber 204 has a slot 205, which is connected to the filter chamber 204. A mounting plate 206 is inserted into the slot 205 by bolts, and a filter screen 207 is installed at the bottom of the mounting plate 206.

[0023] The filter screen 207 can block and filter dust particles carried in the gas, reducing the amount of dust particles that directly enter the adsorption tank 301. At the same time, the filter screen 207 can be quickly removed and replaced by bolt installation.

[0024] Both sides of the filter screen 207 are equipped with sealing gaskets 208.

[0025] The sealing gasket 208 can increase the sealing performance at the connection between the filter screen 207 and the filter chamber 204.

[0026] The desorption assembly 5 includes a steam generator 501, a steam inlet pipe 502, a second connecting pipe 503, a second air pump 504, and a collection tank 505. The steam generator 501 is installed on one side of the top of the base 1. The steam inlet pipe 502 is installed on the top of the steam generator 501 and is connected to each adsorption tank 301.

The collection tank 505 is installed on the other side of the top of the base 1 and is connected to the other end of the second connecting pipe 503.

[0027] The desorption component 5 regenerates the adsorption tank 301 with steam, while the condensate and other substances generated during desorption flow into the collection tank 505 for collection.

[0028] The controller 6 is installed on one side of the top of the base 1.

[0029] The controller 6 is electrically connected to the first solenoid valve 303, the second solenoid valve 506, the third solenoid valve 507, the diverter valve 402, the first air pump 203, and the second air pump 504, respectively, so as to facilitate the control of the overall circuit of the device.

[0030] Working Principle: When using this adsorption-desorption device for chemical production, the operator first connects the gas to be treated to the inlet assembly 2 through a pipeline. The filter cartridge 202 pre-treats the gas, blocking and filtering dust particles carried in the gas, reducing the amount of dust particles directly entering the adsorption tank 301. The pre-treated gas enters the first adsorption tank 301, where it adsorbs harmful components. At this time, the first solenoid valve 303 located above the first adsorption tank 301 opens, while the other first solenoid valves 303 close. The diversion valve 402 controls the main exhaust pipe 401 to be fully open. The operator can then collect and test the treated gas. If the gas reaches... Once the emission standards are met, subsequent continuous treatment can begin. If the gas does not meet the emission standards, the staff will open the first solenoid valve 303 above the second adsorption tank 301 and simultaneously control the diversion valve 402 located between the first and second adsorption tanks 301 to close the main exhaust pipe 401 and open the first connecting pipe 403 below it. At this time, the gas enters the second adsorption tank 301 through the first connecting pipe 403 for treatment. Then, the staff will test the gas that has been treated twice and discharged. If it meets the standards, it can be discharged directly. If it does not meet the standards, the staff needs to repeat the above steps to introduce a sufficient number of adsorption tanks 301 until the discharged gas meets the emission standards.
