Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a wet high-voltage electrostatic precipitator. Background Technique

[0002] Electrostatic precipitation is a common gas dust removal method. After the dust-containing gas passes through a high-voltage electrostatic field, it will be electrically separated. The dust particles will combine with the negatively charged ions generated by ionization to carry a negative charge, and then tend to the anode and accumulate and deposit on the anode surface. Electrostatic precipitation is used in industrial fields such as metallurgy and chemical industry to avoid environmental pollution caused by a large amount of soot gas generated during industrial production.

[0003] In the existing technology, the nozzles of the water spraying mechanism of some wet high-voltage electrostatic precipitators are installed at the top of the precipitator, which leads to a limited water spraying range of the nozzles, resulting in dead corners when flushing the high-voltage positive plate and incomplete cleaning, so that the dust adsorbed on the high-voltage positive plate is not cleaned thoroughly enough. After long-term use, excessive dust accumulates on the dust collection plate, resulting in a reduction in the dust collection effect. At the same time, the precipitator will consume a large amount of water resources during the dust collection process, causing waste of water resources. Therefore, a wet high-voltage electrostatic precipitator is proposed. Summary of the Utility Model
