[0048] A method for treating ethylene oxide tail gas, comprising the following steps:

[0049] S1: When the ethylene oxide tail gas needs to be treated, the operator transports the ethylene oxide tail gas to the buffer box 401 through the air inlet pipe opened on the top of the buffer box 401, and performs preliminary filtration through the filter mechanism 4, and then transports it to the treatment box 301 through the air guide pipe 3 403 for treatment;

[0050] S2: When the ethylene oxide tail gas enters the processing box 301, it will contact and merge with the processing liquid below the partition box 317 in the processing box 301 for processing. When the ethylene oxide tail gas is continuously input, the gas pressure in the processing box 301 can be increased, and then the gas can enter the expansion airbag 302 through the air guide pipe 324, so that the expansion airbag 302 can be expanded.

[0051] S3: When the inflatable airbag 302 inflates, the blocking plate 320 can be indirectly moved, thereby opening the gas outlet, discharging the ethylene oxide tail gas after being fused with the treatment liquid, thereby reducing the pressure, and driving the scraper 406 to clean the filter screen 402;

[0052] S4: After the ethylene oxide tail gas is transported into the buffer box 401 through the air inlet pipe opened at the top of the buffer box 401, the ethylene oxide tail gas can be preliminarily filtered by the filter screen 402 installed inside the buffer box 401;

[0053] S5: When the ethylene oxide tail gas is discharged above the split box 317 after being fused with the treatment liquid, it can be fused with the treatment liquid sprayed from the spray head 502, and then the ethylene oxide tail gas can be further treated, thereby improving the treatment effect. When the treatment liquid on the split box 317 is reduced, the position of the floating plate 506 can be adjusted, and then the position of the blocking plate 320 can be adjusted.

[0054] The implementation principle of the ethylene oxide tail gas treatment method and equipment of the present embodiment is as follows: when the ethylene oxide tail gas needs to be treated, the operator transports the ethylene oxide tail gas to the buffer box 401 through the air inlet pipe opened at the top of the buffer box 401, and performs preliminary filtration through the filter mechanism 4, and then transports it to the treatment box 301 through the air guide pipe 3 403 for treatment. When the ethylene oxide tail gas enters the interior of the treatment box 301, it will contact and merge with the treatment liquid below the dividing box 317 in the treatment box 301 for treatment. The continuous entry of the ethylene oxide tail gas can increase the air pressure inside the treatment box 301. When the internal gas When the pressure reaches a certain level, the gas will enter the expansion airbag 302 through the air guide tube 1 324, so that the expansion airbag 302 can be expanded. As the expansion airbag 302 expands, it can squeeze the force-bearing plate 304 to slide on the inner wall of the adjustment box 303, and the sliding of the force-bearing plate 304 drives the telescopic rod 1 305 to expand and contract and squeeze the spring 1 306. As the force-bearing plate 304 slides, it can squeeze the air inside the adjustment box 303, and then the air inside the adjustment box 303 can be transported to the piston box 1 308 through the air guide tube 2 307, and then the piston plate 1 309 can slide inside the piston box 1 308, and through the piston plate 1 The sliding of 309 drives the piston rod 1 310 to move, and the movement of the piston rod 1 310 drives the connecting rod 311 to move, and the movement of the connecting rod 311 drives the moving plate 1 312 to slide on the guide rod 1 313, and the sliding of the moving plate 1 312 can squeeze the spring 2 315, and as the connecting rod 311 moves, the limiting plate 316 can be driven to move out of the limiting groove, and the limiting fixation of the blocking plate 320 can be cancelled. At this time, the elastic force of the tension spring 323 can drive the moving plate 2 319 to slide on the guide rod 2 318, and the blocking plate 320 can be moved by the sliding of the moving plate 2 319. The baffle 320 can move into the interior of the split box 317, thereby opening the air outlet, and then the ethylene oxide tail gas that has been fused with the treatment liquid can be discharged to the top of the split box 317 through the air outlet, and the sliding of the movable plate 319 can drive the fixed rod 321 to move. When the ethylene oxide tail gas is discharged to a certain extent, the air pressure is reduced. At this time, the force plate 304 is reset by the elastic force of the spring 1 306, and the limit plate 316 is reset by the elastic force of the spring 2 315, so that the air outlet can be blocked and the next filtration can be carried out, so that the ethylene oxide tail gas can be better processed and fused, thereby improving the working efficiency of the processing equipment;

[0055] When it is necessary to process the ethylene oxide tail gas, the operator transports the ethylene oxide tail gas to the buffer box 401 through the air inlet pipe opened at the top of the buffer box 401. At this time, the ethylene oxide tail gas can be preliminarily filtered by the filter 402 installed inside the buffer box 401, and the preliminarily filtered ethylene oxide tail gas can be transported to the processing box 301 through the air guide pipe three 403 for processing. The ethylene oxide tail gas can be further processed by starting the processing mechanism 3, so that the fixed rod 321 can be moved, and the movement of the fixed rod 321 can drive the movable sleeve 1 405 to slide on the guide rod three 404, and the sliding of the movable sleeve 1 405 drives the scraper 406 to move. The scraper 406 moves to scrape and clean the impurities on the filter 402, so that the filter 402 can be effectively prevented from being blocked after long-term use, thereby improving the filtering efficiency and better performing the processing work;

[0056] When it is necessary to treat the ethylene oxide tail gas, the operator transports the ethylene oxide tail gas to the buffer box 401 through the air inlet pipe opened at the top of the buffer box 401, performs preliminary filtration on the ethylene oxide tail gas through the filtering mechanism 4, transports the ethylene oxide tail gas after preliminary filtration to the treatment box 301, and further treats the ethylene oxide tail gas by starting the treatment mechanism 3. When the ethylene oxide tail gas after the treatment liquid fusion treatment is discharged to the top of the split box 317 through the air outlet, the external treatment liquid is passed through the opening The liquid inlet pipe at the top of the treatment box 301 is transported to the spray head 502. By starting the spray head 502, the ethylene oxide tail gas can be sprayed, so that the ethylene oxide tail gas can be further treated. Since the gas outlet is in a closed state at this time, the sprayed treatment liquid will accumulate on the partition box 317. As the treatment liquid gradually accumulates, the floating plate 506 can float up. The floating plate 506 can drive the movable sleeve 2 505 to slide on the guide rod 4 503. When the spring 512 is pressed by the sliding of the 505, the accumulated treatment liquid can enter the bottom of the partition box 317 through the air outlet. At this time, due to the decrease in the buoyancy of the floating plate 506, the floating plate 506 can be reset by the elastic force of the spring 512. As the floating plate 506 moves, the telescopic rod 507 can be driven to move. The movement of the telescopic rod 507 drives the piston plate 508 to slide inside the piston box 509. The sliding of the piston plate 508 can squeeze the air inside the piston box 509. , so that the air inside the piston box 509 is transported to the telescopic airbag 511 through the air guide pipe 510, so that the telescopic airbag 511 can expand and contract, and then drive the movable plate 319 to move. The movement of the movable plate 319 can drive the blocking plate 320 to move, and then the blocking plate 320 can be reset to block and close the air outlet for the next processing work, so that the ethylene oxide tail gas can be processed more conveniently and the processing speed of the processing equipment for the ethylene oxide tail gas can be effectively improved.
