Wet Electrostatic Precipitator (ESDC Series)

Product Overview

The ESDC Series Wet Electrostatic Precipitator is high-efficiency industrial dust removal equipment designed for ultra-fine particulate matter, mist and flue gas purification. It is widely used to eliminate fine dust, acid mist, tar and aerosol pollutants in complex industrial waste gas.

The unit sprays water mist directly onto discharge electrodes and corona zones. Water mist becomes charged and splits inside the strong corona field generated by spiked electrodes to achieve secondary atomization. Combined effects including electric field force, collision interception and adsorption coagulation capture dust particles. Driven by the electric field, particles migrate toward collecting electrodes and are trapped.

Unlike dry electrostatic precipitators that rely on rapping to drop dust into hoppers, this wet model sprays water over collecting plates to build a continuous water film. The flowing water washes captured dust into ash hoppers and removes pollutants with wastewater.

Working Principle

1. Water mist is injected to discharge electrodes and corona areas;

2. Water mist is charged, split and further atomized within the strong corona field;

3. Electric field force, collision interception and coagulation jointly trap fine dust particles;

4. Charged particles move to collecting plates under electric field force;

5. Continuous water film on plates washes dust into ash hoppers for wastewater discharge, eliminating rapping system.
