Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a tail gas treatment liquid circulation filtering device. Background Art

[0002] The exhaust treatment liquid circulation filter device is a device specially designed to treat pollutants in exhaust gas generated by automobiles, factories or other emission sources. Its core function is to effectively remove harmful substances in exhaust gas through circulation filtration, so as to achieve the purpose of environmental protection and emission reduction. The exhaust treatment liquid circulation filter device introduces the exhaust gas generated by the emission source into the treatment device through the exhaust collection system, such as pipes or exhaust hoods. Before the exhaust gas enters the main filtration system, it will pass through the pretreatment unit. The circulation filtration system is the core part of the exhaust treatment liquid circulation filtration device. In addition, the circulation filtration system is also equipped with a circulation pump and pipeline, so that the treatment liquid can be recycled, improving the treatment efficiency and reducing the operating cost.

[0003] For example, the Chinese patent "A Tail Gas Treatment Liquid Outlet Filter Device" with announcement number CN216878263U includes a urea solution tank, a guide tube is provided at the outer end of the urea solution tank, a forked conduit is provided at the lower end of the guide tube, a convex filter screen cylinder is inserted into the inner surface of the outer end of the guide tube, the inner surface of the convex filter screen cylinder is filled with filter cotton, an external thread is provided at the outer end of the guide tube, a plugging cover is fixed to the outer surface of the guide tube through a threaded connection, the plugging cover squeezes and fixes the convex filter screen cylinder, the convex filter screen cylinder is attached to the inner surface of the forked conduit, a first valve is provided on the outer surface of the guide tube, a second valve is provided at the outer end of the forked conduit, a sealing gasket is placed on the inner surface of the plugging cover, the sealing gasket is made of rubber material, the convex filter screen cylinder is tightly attached to the inner surface of the guide tube, the convex filter screen cylinder is made of stainless steel, the plugging cover adopts a hexagonal concave cover structure, and a hexagonal incision is provided on its outer end surface.

[0004] Although the above-mentioned existing technology can realize the filtering of the treatment liquid, in actual use, on the one hand, the one-time filtration of the treatment liquid is prone to clogging of the filter screen. After the exhaust gas is treated, the treatment liquid contains impurities in the exhaust gas. The treatment liquid containing impurities is directly discharged into the filter tank, causing the filter screen to be blocked by larger impurity particles, thereby reducing the filtration efficiency. On the other hand, it is difficult to deal with the sediment generated by the treatment liquid when it is not used for a long time. The sediment generated in the liquid after the treatment liquid is not used for a long time will cause the liquid outlet pipe to be blocked, thereby shortening the service life of the filter device. Therefore, it does not meet the existing needs. In this regard, we propose an exhaust gas treatment liquid circulating filtration device. Utility Model Content

[0005] The utility model aims to provide a tail gas treatment liquid circulation filtering device to solve the problems in the above background technology that the treatment liquid is easily clogged by one-time filtration and it is difficult to handle the sediment generated by the treatment liquid when it is not used for a long time.

[0006] To achieve the above object, the utility model provides the following technical solutions: a tail gas treatment liquid circulation filtering device, comprising a base, a filter tank is fixedly arranged on one side of the upper end of the base, a tank cover is arranged on the upper end of the filter tank, and the tank cover and the filter tank are connected by a buckle, a liquid inlet pipe is fixedly arranged on the upper end of the tank cover, and the liquid inlet pipe is connected to the filter tank; and further comprising:

[0014] Preferably, a heating cavity is provided inside the side wall of the filter tank, and the heating cavity is distributed in a spiral shape, and a heating wire is provided inside the heating cavity.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can perform preliminary filtration on the treated liquid through the filter cartridge and the limit block. After the treated liquid completes the treatment of the exhaust gas, it is discharged into the filter tank through the liquid inlet pipe. At this time, the treated liquid first enters the filter cartridge, and the filter cartridge intercepts the larger solid impurity particles in the treated liquid. At this time, the treated liquid that passes through the filter cartridge drips onto the filter frame. After the filter cartridge has been used for a period of time, the tank cover is opened and the filter cartridge is rotated to make the limit block on the filter cartridge slide in the fixed groove until the limit block coincides with the slot position. At this time, the filter cartridge is pulled downward to separate the filter cartridge from the fixed seat and process the impurities in the filter cartridge. When installing the filter cartridge, align the limit block on the filter cartridge with the slot opening and push it into the slot, rotate the filter cartridge, and at this time the limit block on the filter cartridge slides into the fixed groove, so that the filter cartridge is fixed on the fixed seat, making the treated liquid filtration more refined while also facilitating the disassembly and assembly of the filter cartridge.

[0017] 2. The utility model can stir the filtered treatment liquid through the motor and the stirring frame. When the treatment liquid is filtered and not used for a long time, the compounds in the treatment liquid form precipitation and flocs. When the treatment liquid is used again, the motor is turned on to make the output shaft of the motor drive the rotating disk to rotate. While the rotating disk rotates, the stirring frame rotates and stirs the treatment liquid to redissolve the precipitation and flocs in the treatment liquid. Wait for a period of time before using the treatment liquid to avoid clogging of the water pump caused by the precipitation and flocs, thereby extending the service life of the filtering device.

[0018] 3. The utility model can further filter the treated liquid through the filter screen. When the treated liquid drips onto the filter frame through the filter cartridge, the treated liquid first passes through the filter screen to filter the particulate matter. The filtered treated liquid passes through the activated carbon filter layer. The activated carbon removes organic matter, odor and certain harmful gases in the exhaust treatment liquid. The ion exchange resin layer removes ionic pollutants in the treated liquid. Through the ion exchange effect, harmful ions are replaced by harmless ions, reducing the conductivity of the liquid. Finally, the treated liquid drips through the filter screen to the bottom of the filter tank, further improving the filtering effect of the treated liquid. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the treatment liquid passing through the filter cartridge 10 drips onto the filter frame 17. When the filter cartridge 10 has been used for a period of time, the tank cover 3 is opened and the filter cartridge 10 is rotated so that the limit block 9 on the filter cartridge 10 slides in the fixed groove 8 until the limit block 9 coincides with the position of the slot 21. At this time, the filter cartridge 10 is pulled downward to disengage the filter cartridge 10 from the fixed seat 7 and the impurities in the filter cartridge 10 are processed. When installing the filter cartridge 10, the limit block 9 on the filter cartridge 10 is aligned with the opening of the slot 21 and pushed into the slot 21. The filter cartridge 10 is rotated. At this time, the limit block 9 on the filter cartridge 10 slides into the fixed groove 8 to fix the filter cartridge 10 on the fixed seat 7.
