[0027] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , an auxiliary mechanism 6 is installed at the bottom end of the condensation tank 2, and the auxiliary mechanism 6 includes a movable plate 601, a scraper 602, an electric push rod 603, a screw 604 and a motor 605. The screw 604 is installed in the inner wall groove of the bottom end of the condensation tank 2 through a bearing, and the outer side of the condensation tank 2 is installed with a motor 605 connected to the screw 604 through a coupling, and the outer side of the screw 604 is threadedly sleeved with a movable plate 601, and an electric push rod 603 is installed in the built-in groove of the movable plate 601. The scraper 602 is connected to the bottom of the electric push rod 603, and the scraper 602 and the movable plate 601 are slidably sleeved. The end of the movable plate 601 away from the screw 604 is slidably connected to the inner wall groove of the condensation tank 2, and the cross-sectional shape of the scraper 602 is "L"-shaped.

[0028] During specific implementation, after the xylene waste gas passes through the condensation tube 11 in the condensation tank 2, a part of the waste gas will condense into xylene liquid, which can be reused. After these xylene liquids fall to the bottom of the condensation tank 2, they need to be discharged, but some xylene liquids may be retained on the inner wall of the bottom end of the condensation tank 2, reducing the drainage efficiency. When discharging the xylene liquid, the motor 605 can be started to drive the screw 604 to rotate, and then the movable plate 601 and the screw 604 are threadedly engaged to make the movable plate 601 move to one side on the screw 604, and at the same time, the electric push rod 603 pushes the scraper 602 downward to fit the inner wall of the bottom end of the condensation tank 2.

The two ends of the filter plate 10 are connected to the docking block 906, and one side of the docking block 906 is connected to the vertical rod 905. The fixed box 4 is close to the docking block 906 and A docking groove 901 is provided on the inner side of the vertical rod 905, and a fastening ring 904 is sleeved on the outer side of the vertical rod 905.

[0030] During specific implementation, the exhaust gas in the condensation tank 2 of the xylene purification device will be adsorbed and purified by multiple activated carbon adsorption plates 12, and then the purified exhaust gas will be discharged through the exhaust fan 14. However, some exhaust gas may not be completely purified when it reaches the exhaust fan 14, and can be filtered and purified through the filter plate 10. When it is necessary to regularly disassemble and replace the filter plate 10, the fastening ring 904 can be rotated to drive the connecting block 903 to rotate in the slide groove 902, so that the fastening ring 904 and the vertical rod 905 are threadedly engaged, and the fastening ring 904 can be quickly removed from the vertical rod 905, and then the filter plate 10 can be pulled outward, so that the filter plate 10 drives the docking block 906 and the vertical rod 905 to slide to one side in the docking groove 901, and the filter plate 10 can be quickly removed and replaced, thereby improving the purification quality and efficiency of the xylene purification device.

[0031] Working principle: When using the xylene purification device, first, the waste gas generated by xylene production enters the condensation tank 2 from the air inlet pipe 8, and the waste gas rises from the bottom to the top. At the same time, the waste gas is condensed through the condensation pipe 11 and the condensation plate 13. Some xylene liquid produced by condensation falls on the inner wall of the bottom end of the condensation tank 2, and the other part of the waste gas rises upward and adsorbs the toxic substances in the waste gas through the adsorption plate 12. Then the exhaust fan 14 drives the guide pipe 3 to drive the waste gas into the fixed box 4, and is filtered and adsorbed again through the filter plate 10. Finally, the purified waste gas is discharged through the exhaust pipe 5. When the filter plate 10 needs to be disassembled and replaced, the filter plate 10 can be quickly disassembled and replaced through the filtering mechanism 9, which improves the working efficiency and practicality of the xylene purification device.
