[0017] 4. The modular structure of flange connections and locking grooves for each treatment tower and adsorption tower ensures sealing performance while facilitating disassembly and maintenance. The standardized design of each treatment chamber allows for interchangeability, reducing manufacturing and maintenance costs and improving the practicality and ease of maintenance of the equipment.

[0018] 5. The guide plate and the T-shaped first connecting pipe work together to guide the centralized discharge of waste liquid.

The bottom shell protrusion and the collection pipe quickly collect waste liquid to achieve drug recycling. The first treatment tower 2 is equipped with pH-adjusting liquid pretreatment. Its top third connecting pipe 12 is connected to the internal pure water washing system via the second connecting pipe 11. The second treatment tower 3, which has the same structure, is connected to the third treatment tower 4. The second treatment tower 4 is treated in stages, first neutralizing acid and alkaline pollutants and then washing impurities to improve the purification accuracy. The same structure makes it easy to interchange and maintain, thereby reducing operating costs. The third connecting pipe 12 at the top of the second treatment tower 3 is connected to the third treatment tower 4 through the second connecting pipe 11. The bottom of the third treatment tower 4 is connected to the first connecting pipe 9, which has a straight structure at the top and is not equipped with a guide plate 901. Its bottom shell 202 structure is the same as that of the second treatment tower 3. The straight pipe reduces the resistance to the flow of exhaust gas to ensure stable flow. The unified structure facilitates standardized production and component replacement. The bottom shell 202 of the third processing tower 4 is bolted to a third processing chamber 401 with a circular through-hole structure on the inner side and the same connection structure at both ends as the first processing chamber 203. A corrugated demister plate 406 is fixed inside the third processing chamber 401, supported at the bottom by a mesh steel wire.

A fourth processing chamber 402 with the same bolted structure is bolted to the top of the third processing chamber 401 and bolted to a second top cover 403. The top of the second top cover 403 is connected to a third connecting pipe 12. The corrugated demister plate 406 increases the contact area for efficient demisting. The motor 405 drives the scraper 404 to periodically clean accumulated liquid to prevent blockage. The steel wire support enhances the structure's impact resistance. The second top cover 403 is connected to a surface cooler 5 via the third connecting pipe 12 and the second connecting pipe 11. The surface cooler 5 is connected to an induced draft fan. 14. The induced draft fan 14 is connected to the fifth connecting pipe 16, which is F-shaped and has three flange interfaces on the side, through the fourth connecting pipe 15. One end of the fifth connecting pipe 16 is fixed to itself with bolts, and the other three interfaces are each connected to a fourth connecting pipe 15. The fifth connecting pipe 16 is connected to the first adsorption tower 6, the second adsorption tower 7, and the third adsorption tower 17, which are in parallel structure with the first treatment tower 2 and the second treatment tower 3, through the fourth connecting pipe 15.

High-pressure steam is introduced into the spray pipe 13 for desorption. The bottom fourth connecting pipe 15 is a four-way passage and is connected to the liquid storage tank at the bottom. The parallel design realizes the alternating operation of adsorption and desorption to continuously treat the waste gas. High-pressure steam desorption thoroughly improves the regeneration efficiency of the adsorbent. The four-way passage facilitates the recovery of waste liquid. The series connection can perform multi-stage adsorption for high-concentration waste gas to improve the resin recovery rate and adapt to different working conditions.

[0023] Working principle: When using an industrial gas waste gas resin adsorption-desorption-condensation recovery device, the resin-containing waste gas first enters the first treatment tower 2 through the third connecting pipe 12. The first treatment tower 2 is equipped with a pH adjusting solution. The waste gas and the solution are fully in contact in the layered structure of the first treatment chamber 203 and the second treatment chamber 205. The waste gas is evenly sprayed through the six pairs of nozzles of the spray pipe 13 to neutralize the acidic or alkaline substances in the waste gas. The waste liquid generated by the pretreatment flows into the solution recovery device through the first connecting pipe 9 and the liquid collection pipe 10 at the bottom of the bottom shell 202. The treated waste gas enters the second treatment tower 3 through the second connecting pipe 11. The pure water in the second treatment tower 3 performs a second washing of the waste gas to remove residual impurities and ensure the initial purification of the waste gas. The pretreated exhaust gas enters the third treatment tower 4 from the top of the second treatment tower 3. The corrugated demister plate 406 in the third treatment tower 4 removes the mist droplets in the exhaust gas by collision interception. The motor 405 drives the scraper 404 to periodically scrape off the accumulated liquid on the demister plate 406 to prevent blockage. The demisted exhaust gas enters the surface cooler 5 through the second top cover 403. The surface cooler 5 cools the exhaust gas to a temperature suitable for adsorption. Then, the exhaust gas is transported to the adsorption unit by the induced draft fan 14 through the fourth connecting pipe 15. The induced draft fan 14 sends the cooled exhaust gas into the fifth connecting pipe 16. The fifth connecting pipe 16 is connected in parallel to the first adsorption tower 6, the second adsorption tower 7, and the third adsorption tower 17 through the fourth connecting pipe 15. After the exhaust gas enters the adsorption tower, the adsorbent inside, such as the modified molecular sieve, adsorbs the resin components. The purified gas is discharged through the third connecting pipe 12 and the exhaust pipe 8. When a certain adsorption tower reaches adsorption saturation, high-pressure steam is introduced through the spray pipe 13 for desorption: the high-pressure steam heats the adsorbent, causing the resin components to desorb and form steam. The desorbed resin-containing steam enters the condensation and recovery unit through the third connecting pipe 12 and the second connecting pipe 11. At the same time, other adsorption towers continue to operate to ensure continuous processing. After the mixed gas containing resin vapor is further cooled by the surface cooler 5, it becomes liquid resin under the action of condensation. It flows into the storage tank for storage and recycling through the four-way passage of the fourth connecting pipe 15. The uncondensed gas is discharged by the induced draft fan 14. The fourth connecting pipe 15 at the bottom of the adsorption tower is connected to the storage tank to ensure that the waste liquid after desorption is collected in time and realize the recycling of resin resources.
