It has a wide range of applications, high purification efficiency, low equipment resistance, and small footprint, and is mostly used in chemical plants.

[0003] For example, the utility model with application number 202023240893.7 discloses an acid mist recovery device for an acid mist tower, which can filter the liquid medicine after acid mist treatment for secondary use, greatly improving environmental protection and saving time for cleaning after use.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The acid mist recovery device used in this type of acid mist tower first has a small contact area between the acid mist and the drug, which cannot be fully mixed, and has low efficiency and poor effect in the recovery and treatment of the acid mist. Secondly, the impurities in the acid mist are not filtered, so the drugs that react with the acid mist are easily deposited with impurities, increasing the frequency of drug filtration, which not only increases energy consumption but also brings inconvenience to the staff.

[0006] Therefore, an acid mist recovery device for an acid mist tower is designed to optimize the above problems. Utility Model Content

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides an acid mist recovery device for an acid mist tower. Through the coordinated use of a tower body, a partition plate, a tower top, a mist inlet pipe, a filter frame, a fixed pipe, a motor, a rotating shaft, a sleeve, a rotating pipe and a through hole, the outputted acid mist can be fully contacted with a liquid medicine and reacted. The liquid medicine and acid mist bubbles can also be stirred while the acid mist is output, so that the two can be more fully contacted, thereby improving the recovery efficiency and reaction effect of the acid mist, thereby meeting people's use needs.

[0017] Through the coordinated use of the fixed rod, brush plate, bristles and filter screen, the acid mist entering the filter frame through the mist inlet pipe is initially filtered by the filter screen to remove impurities in the acid mist. The rotation of the sleeve drives the fixed rod and the brush plate to rotate, so that the bristles rotate and clean the mesh of the filter screen to keep the filter screen unblocked, thereby improving the initial treatment efficiency of the acid mist, reducing the contamination of impurities to the medicine, and improving the utilization rate of the medicine.

[0018] Through the coordinated use of a recovery pipe, a filter cartridge, a pump body, an output pipe, an annular pipe and a nozzle, the valve on the recovery pipe is opened to allow the medicine liquid on the isolation plate to flow into the interior of the filter cartridge through the recovery pipe, so that the medicine liquid is filtered from bottom to top, and then the pump body is opened, and the filtered or filtered medicine liquid is sucked into the output pipe through the internally installed pipeline, and transported to the annular pipe and evenly sprayed into the interior of the tower body by the nozzle. The medicine liquid can be filtered during use, thereby improving the recovery efficiency of the acid mist, and the annularly sprayed medicine liquid can better contact and react with the acid mist, thereby improving the practicality of the acid mist recovery device for the acid mist tower.
