Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, and particularly relates to a high-efficiency water-saving wet electrostatic dust removal device. Background Technology

[0002] A wet electrostatic precipitator is an industrial flue gas purification device used to treat pollutants such as trace dust, PM2.5, aerosols, and acid mist. It achieves dust removal by forming a water film through water spraying or overflow. It is suitable for deep purification after wet desulfurization. However, water needs to be continuously added during the dust removal process. Currently, wet dust collectors generally filter the used water and recycle it to achieve water conservation.

[0003] The water tank filtration mechanism of existing wet scrubbers is too simple. Usually, only a filter screen is installed inside the water tank, and then water flows down through the top of the filter screen for filtration. This filtration method causes the filtered dirt to accumulate on the surface of the filter screen, requiring frequent cleaning. Cleaning requires opening the water tank and stopping the operation, which is not only time-consuming and labor-intensive, but also affects the normal dust removal work. Utility Model Content

[0004] This utility model provides a high-efficiency, water-saving wet electrostatic precipitator, which aims to solve the problem that the water circulation filtration mechanism of current wet dust collectors needs to be cleaned frequently, which is laborious and also affects the normal operation of dust removal.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0013] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0014] This utility model embodiment provides a high-efficiency, water-saving wet electrostatic precipitator, such as... Figure 1-3 As shown, the system includes a dust collector 1 and a water tank 2. The dust collector 1 and the water tank 2 are connected by a return pipe 3 and a water inlet pipe 4. A filter screen 5 is installed on the inner wall of the water tank 2. A water pump 6 is installed inside the water tank 2. The water inlet pipe 4 is connected to the outlet of the water pump 6. A rotating shaft 7 is rotatably installed at the center of the top of the water tank 2. A motor 8 is installed at the outer end of the top of the water tank 2. The output shaft of the motor 8 is connected to the top of the rotating shaft 7. A connecting block 9 is connected to the bottom of the rotating shaft 7. Two sets of brush rollers 10 are symmetrically installed on the side wall of the connecting block 9. The brush rollers 10 are cylindrical and rotatably installed. The roller 10 has a brush-like surface that fits against the lower surface of the filter screen 5. The inlet of the return pipe 3 is located below the filter screen 5, and the inlet of the water inlet pipe 4 is located above the filter screen 5. A groove is provided at the bottom of the rotating shaft 7, and a slider 11 is slidably embedded in the groove. A connecting rod 12 is connected to the bottom of the slider 11, and a connecting block 9 is installed at the lower end of the connecting rod 12. A spring 13 is sleeved on the outside of the connecting rod 12, and the two ends of the spring 13 are respectively connected to the lower side of the slider 11 and the inner wall of the groove of the rotating shaft 7. This dust removal device consists of a dust collector 1 and a water tank 2. Water is drawn from the inside of the water tank 2. Pump 6 pumps water into dust collector 1 through inlet pipe 4 for humidification and dust removal. Wastewater from dust removal flows back to water tank 2 through return pipe 3. The water in water tank 2 permeates upwards from the bottom of filter screen 5 for filtration. The filtered water is then pumped back into dust collector 1 by pump 6, thus achieving water circulation and saving water. A brush roller 10 is provided. After prolonged filtration, some dirt may clog the mesh openings on the lower surface of filter screen 5. At this time, motor 8 can be started. Motor 8 drives brush roller 10 to rotate via shaft 7, and brush roller 10 adheres to the lower surface of filter screen 5. The surface is rotated for cleaning. The brush roller 10 is rotatably mounted, so when the brush roller 10 rotates, it can rotate on its own under the friction of the filter screen 5. When the brush roller 10 rotates, the brush will insert into the mesh of the filter screen 5 and push out the blocked dirt, thereby effectively cleaning the filter screen 5. A spring 13 is provided, and the elastic force generated by the spring 13 causes the slider 11 to pull the connecting rod 12 upward. Therefore, the connecting block 9 applies pressure to the brush roller 10, so that the brush roller 10 is in close contact with the surface of the filter screen 5, thereby improving the cleaning effect and ensuring long-term stable and effective filtration of circulating water.

[0015] Connecting shafts 14 are rotatably mounted on both ends of connecting block 9. Threads are provided on the surface of connecting shaft 14. Brush roller 10 is installed on the outside of connecting shaft 14 by means of threaded connection. This setting allows brush roller 10 to be rotated and disassembled from the surface of connecting shaft 14, thus facilitating the subsequent replacement of brush roller 10.

[0016] The surface of the connecting shaft 14 is provided with a circular slot. This feature allows tools to be inserted into the slot to limit the connection shaft 14 during the assembly and disassembly of the brush roller 10, thereby improving the ease of assembly and disassembly of the brush roller 10.

[0017] A fixing rod 15 is installed at the bottom of the connecting block 9, and a stirring blade 16 is installed on the surface of the fixing rod 15. A feeding pipe 17 is connected to the lower right side of the water tank 2. With the stirring blade 16 and the feeding pipe 17, some impurities need to be removed from the water by chemical means with the help of decomposition material. The decomposition material is added through the feeding pipe 17. After being added, the connecting block 9 can drive the stirring blade 16 to stir the inside of the water tank 2 through the fixing rod 15, so that the decomposition material can be dissolved quickly.

[0018] The bottom of the inner wall of water tank 2 is set as an arc surface. The bottom of water tank 2 is provided with an opening, and a sludge collection box 18 is installed below the opening. A valve is provided at the opening of the sludge collection box 18. With the sludge collection box 18, the impurities filtered by the filter screen 5 will remain at the bottom of water tank 2 under the action of gravity. The sludge collection box 18 can collect the dirt in water tank 2 and also prevent the dirt from being stirred inside water tank 2 and floating.
