Wet electrostatic precipitator

Wet electrostatic precipitators are widely used in various industries such as plastic granulation, waste incineration, acid mist in electroplating plants, smoke from setting machines, quenching furnaces, tempering furnaces, large-scale casting, rubber cracking waste gas, thick smoke treatment, tar treatment, water mist treatment, etc.

Wet electrostatic precipitator is an electrostatic precipitator that uses water spray or overflow water to form a water film on the surface of the dust collecting electrode, achieving plate cleaning. Wet cleaning can avoid the re flying of settled dust and achieve high dust removal efficiency. Due to the absence of a vibration device, the operation is relatively stable, but there are issues with corrosion, sludge, and sewage treatment. The application is not as widespread as dry electrostatic precipitators.

The main function of a wet electrostatic precipitator is to remove dust particles from dusty gases while also removing gaseous pollutants such as water vapor from the gas. It can be used for dust removal, as well as for cooling and purifying gases.

Working principle of wet electrostatic precipitator:

The electrostatic force generated by a high-voltage electric field is used to charge the dust in the flue gas, and the charged dust is separated from the airflow under the action of the electric field, moving towards the anode and cathode respectively and adhering to them. Then, the dust is cleaned by a vibration device, and the accumulated dust falls into the ash hopper. The smoke contains oil and has high humidity, and flows down to the lower cone hopper through wet cleaning to achieve the purpose of dust collection.
