Description

Technical Field

[0001] The utility model relates to the technical field of wet electrostatic dust removal, in particular to a wet electrostatic air dust removal device. Background Art

[0002] A wet electrostatic precipitator is an environmental protection treatment equipment for waste gas that uses high voltage to generate static electricity to adsorb dust on the anode to achieve a purification effect. During operation, water is pumped into the spraying assembly through an external water pump and then sprayed on the anode plate and the cathode plate for cleaning.

[0003] In the prior art, when a double-electrostatic waste gas wet electrostatic precipitator is operating, although water is sprayed on the anode plate to form a water curtain on the anode plate, and the dust adsorbed on the anode plate is driven by the downward flow of the water curtain to flow into the bottom of the device, in actual use, the flow rate of the water curtain on the anode plate will gradually decrease, resulting in the impact force of the water curtain in the bottom area of the anode plate being unable to completely clean the dust, and a small amount of dust will still remain on the anode plate, thereby reducing the cleaning effect of the device. Improvement is needed; therefore, a wet electrostatic air dust removal device is proposed for the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the utility model proposes a wet electrostatic air dust removal device.
