The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This embodiment of the present invention provides a corrosion-resistant composite electrode circulating water washing type electrostatic precipitator, comprising, The connecting assembly 100 includes a bracket 101, a fixing block 102 fixedly connected to the end of the bracket 101, a hopper 103 fixedly connected to the side wall of the fixing block 102, a dust collector housing 104 fixedly connected to the end of the hopper 103, and a cover plate 105 fixedly connected to the end of the dust collector housing 104. The end of the cover plate 105 is hinged to the side wall of the dust collector housing 104 by a snap fastener. The cleaning assembly 200 includes a stirring mechanism 201 rotatably connected inside the dust collector housing 104, a limiting plate 202 fixedly installed on one side of the end of the stirring mechanism 201, and a connecting cylinder 203 movably connected to the other side of the end of the stirring mechanism 201. The end of the connecting cylinder 203 is hinged to the side wall of the cover plate 105.

[0019] Specifically, the support frame 101 adopts a frame structure with casters 108 rotating at the four corners of the bottom, providing strong overall rigidity and stable support for the device; the fixing block 102 is fixedly connected to the end of the support frame 101 and rigidly connected to the hopper 103 by bolts; the hopper 103 has a funnel-shaped structure, with its top connected to the bottom of the dust collector housing 104, and a liquid collection tank 206 is fitted at the bottom to guide the washing liquid and dust mixture generated during the dust removal process into the liquid collection tank; the dust collector housing 104 has a square box-shaped sealed structure, forming a dust removal chamber inside, which is the core space for electrostatic dust removal and water washing cleaning; the side wall is fixedly connected to the air inlet pipe 107, and the end is connected to... The cover plate 105 is hinged to the side wall of the dust collector housing 104 by snap-fit. It can be flipped open and closed around the hinge axis, which is convenient for internal maintenance and repair of the equipment. The inner side is hinged to the end of the connecting cylinder 203 to ensure sealing performance. The air inlet pipe 107 is fixedly connected to the lower part of the side wall of the dust collector housing 104. The end is provided with an umbrella-shaped guide hood with the opening facing the inside of the housing, so that the dust-laden gas can be evenly diffused after entering the housing, and avoid local airflow being too fast and affecting the dust removal effect. The caster 108 is rotatably connected to the bottom of the bracket 101. The outer surface is provided with anti-slip texture, which is convenient for the overall movement of the device. The anti-slip texture can enhance the friction with the ground and prevent the equipment from sliding during operation.

[0020] Furthermore, the stirring mechanism 201 is rotatably connected inside the dust collector housing 104 and is the core actuator for circulating water washing. It includes a connecting rod 201a made of corrosion-resistant alloy rod that runs through the dust collector housing 104, with both ends rotatably connected to the limiting plate 202 and the connecting cylinder 203, respectively, providing an installation carrier and transmission support for the stirring paddle. The stirring paddle 201b is fixedly connected to the side wall of the connecting rod 201a, is blade-shaped, and is made of corrosion-resistant material. When it rotates with the connecting rod, it can agitate the washing liquid inside the housing, enhance the contact with the electrodes, and improve the cleaning effect. The fixing ring 201c is fixedly sleeved on the side wall of the connecting rod 201a to limit the installation position of the stirring paddle 201b and prevent it from sliding along the connecting rod axis. The adjusting nut 201d is threadedly connected to the side wall of the fixing ring 201c. By tightening it, the position of the stirring paddle 201b can be further locked, making it easy to adjust the blade spacing according to cleaning needs.

[0021] Preferably, the limiting disc 202 is a circular disc structure, fixedly installed on one side of the end of the stirring mechanism 201, and rotatably engaged with the inner wall of the dust collector housing 104 to limit the radial displacement of the connecting rod 201a and ensure smooth rotation of the stirring mechanism; one end of the connecting cylinder 203 is hinged to the side wall of the cover plate 105, and the other end is rotatably connected to the end of the stirring mechanism 201. The inside is a hollow structure to accommodate the transmission components; one side of the end is fixedly connected to the motor 204, and the other side is fixedly connected to the coupling 205; the motor 204 is fixedly connected to one side of the end of the connecting cylinder 203 to provide power to the stirring mechanism, and the output shaft is driven to rotate the stirring mechanism by the connecting rod 201a through the coupling 205; the coupling 205 is fixedly connected to the other side of the end of the connecting cylinder 203 to transmit the power of the output shaft of the motor 204 to the connecting rod 201a, which can compensate for installation errors and ensure smooth power transmission.

[0022] It should be noted that the exhaust port 106 is fixedly connected to the side wall of the connecting cylinder 203 and communicates with the inside of the dust collector housing 104 to discharge the purified gas; the outer ring is sealed with a flange connected to the external pipeline by bolts, and a sealing gasket is installed between the flange faces to prevent gas leakage; the liquid collection tank 206 is adapted to be installed at the bottom of the hopper 103, and a filter screen is horizontally installed inside to filter dust impurities in the washing liquid and realize the recycling of the washing liquid; the drain port 207 is fixedly connected to the bottom of the liquid collection tank 206, and a drain valve is sealed on the outer ring. By opening and closing the valve, the filtered clean washing liquid can be discharged for circulating water washing or periodically discharging sediment, which is convenient to operate.

[0023] During operation, dust-laden gas enters the dust collector housing 104 evenly through the umbrella-shaped guide hood of the inlet pipe 107, generating corona discharge to ionize the air. After dust particles collide with and become charged by the ions, they are adsorbed onto the surface of the anode plate under the action of the electric field, achieving preliminary gas purification. The motor 204 is started, driving the connecting rod 201a through the coupling 205 to rotate the agitator 201b, stirring the washing liquid water or solution containing corrosion inhibitor in the housing to form a circulation, washing away the dust adsorbed on the surface of the anode plate. The adjusting nut 201d can lock the agitator. Positioning ensures cleaning coverage of all electrode areas; dust-laden waste liquid flows into the collection tank 206 through the hopper 103, where dust is intercepted by a double-layer filter screen, and the filtered cleaning liquid is temporarily stored in the tank; opening the drain valve of the drain port 207 allows the cleaning liquid to be pumped back to the dust collector housing 104 through the return water pipeline for circulating water washing, with only a small amount of sediment being discharged periodically; the purified gas is discharged through the exhaust port 106 of the connecting cylinder 203; when maintenance is required, the buckle of the cover plate 105 can be opened, and the cover plate can be flipped over to expose the internal electrodes and stirring mechanism, making operation convenient.

[0024] In summary, the rigid support of the bracket and fixing block, and the radial limiting of the stirring mechanism by the limiting plate, ensure no significant vibration during equipment operation; the cover plate snap-fit ​​and flange sealing design ensure the airtightness of the shell and prevent gas leakage from polluting the environment; the anti-slip design of the casters makes the device flexible to move and easy to adjust the working position; the hinged structure of the cover plate and the design of the drain valve simplify the internal inspection and sludge cleaning process and reduce maintenance workload; the position of the stirring paddle can be adjusted by adjusting the nut to adapt to electrode structures of different sizes; the umbrella-shaped guide hood ensures uniform airflow and is suitable for the treatment of dusty gases with different flow rates.
