Wet Electrostatic Precipitator Customer Evaluation
Wet Electrostatic Precipitator FAQ
-
What is the main application of Wet Electrostatic Precipitator (WESP)?
It is mainly used for removing fine dust, acid mist, tar, water mist and other pollutants in industrial flue gas, especially in high-humidity working conditions.
-
What is the dust removal efficiency of WESP?
The purification efficiency can reach more than 99% for fine particles and acid mist, meeting strict environmental emission standards.
-
Does the Wet Electrostatic Precipitator cause secondary dust pollution?
No. It uses water washing for ash removal, so there is no re-entrainment of dust, avoiding secondary pollution.
-
What industries is WESP suitable for?
It is widely used in steel, non-ferrous smelting, chemical industry, garbage incineration, coal-fired power plants and other industrial waste gas treatment.
