Description

Technical Field

[0002] Wet electrostatic precipitator uses water spraying or overflow water to form a layer of water film on the surface of the dust collecting electrode to achieve plate cleaning. Wet cleaning can prevent the settled dust from flying again and achieve a very high dust removal efficiency. Because there is no vibration device, the operation is more stable, but there are problems with corrosion, sludge and sewage treatment. Its application is not as extensive as that of dry electrostatic precipitator. Nowadays, there are many types of wet electrostatic precipitators on the market.

[0003] For example, the utility model with announcement number CN213222719U relates to the technical field of electrostatic precipitators, specifically a wet electrostatic precipitator, including a workbench, on which a shell with a hollow structure is fixedly connected by bolts, the front side surface of the shell is provided with an air inlet at the bottom end, the rear side surface of the shell is provided with an exhaust port at the top end, the bottom end of the shell is provided with a sewage pipe, and the air inlet, the exhaust port and the sewage pipe are all connected to the interior of the shell; the wet electrostatic precipitator is driven by a dust removal mechanism, that is, the piston rod of the electric cylinder drives the connecting plate, the connecting rod, the fixed body and a plurality of nozzles to move in the vertical direction. Therefore, when dust removal is performed, the plurality of nozzles move while spraying, so that the surface of the dust collecting plate is comprehensively cleaned from top to bottom, avoiding the situation where local dust is not completely cleaned, thereby ensuring the dust adsorption capacity of the dust collecting plate.

[0004] In the process of implementing this application, it was found that the technology has the following problems: when existing wet electrostatic precipitators discharge and clean the dust after absorbing a large amount of dust, most of them are directly cleaned with a spray device, but a large amount of dust can easily cause blockage of the internal filter plate, and the dust will accumulate quickly, which speeds up the cleaning cycle of the dust collector.

[0005] For this purpose, a wet electrostatic precipitator with automatic sewage discharge is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that most of the existing wet electrostatic precipitators directly use a spray device to clean the dust after absorbing a large amount of dust, but a large amount of dust easily causes the clogging of the internal filter plate.

When the scraper moves to the inner side of the main body, the collecting plate will contact the guide block, causing the dust particles scraped by the top surface of the collecting plate to fall down, and the reset spring can restore the collecting plate to its original position after leaving the guide block.

[0013] Furthermore, the spray assembly includes an infusion pump, an infusion tube is provided at the output end of the infusion pump, a liquid distribution tube is provided at one end of the infusion tube, and a nozzle is provided in an array on the surface of the liquid distribution tube.

[0018] By adopting the above technical solution, the gas containing dust enters the main body from the air inlet pipe, and after being electrostatically precipitated, the gas is discharged from the air outlet pipe.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model is provided with a scraping component and a spraying component in the main body. When the dust collecting plate in the main body collects a large amount of dust particles, the scraping component will first wipe and collect the dust on the surface of the dust collecting plate, and then discharge the sewage under the action of the guide block, and finally the spraying component will clean the scraped dust collecting plate. These designs enable the dust collector to scrape the dust collecting plate before spraying and cleaning, thereby avoiding the blockage of the filter plate caused by a large amount of dust particles and reducing the cleaning cycle of the dust collector.
