What is Dust Collector: Industrial Air Purification
A dust collector is a large-scale air filtration system designed for industrial and workshop environments. It captures and removes harmful dust, chips, and particulate matter generated during manufacturing processes like woodworking, metalworking, or chemical production. By continuously filtering contaminated air from the workspace, it protects worker health, safeguards machinery, and maintains clean, safe operating conditions in industrial facilities.
What Is a Wet Electrostatic Precipitator dust collector?
A Wet Electrostatic Precipitator (WESP) which is also known as a Wet ESP, Tubular Electrostatic Precipitator, or Wet Scrubber ESP that is an advanced Industrial Air Pollution Control System designed to remove fine particulates, aerosols, fumes, heavy metals, and sticky pollutants from industrial exhaust streams. Senotay who are a leading Wet Electrostatic Precipitator Manufacturer in China and delivers high-performance WESP systems engineered for industries requiring ultra-low emission levels.
It is especially effective for:
Submicron particles (<1 micron)
Acid mists (H₂SO₄, HCl, HNO₃)
Tar, oil mist, resin fumes
Sticky, corrosive, or high-moisture gases
WESP offers 99%+ removal efficiency thats making it ideal for industries with strict environmental requirements.
Why Wet Electrostatic Precipitator?
Industries choose WESP systems because they:
Capture extremely fine pollutants that other technologies cannot.
Remove hazardous and corrosive aerosols.
Prevent re-entrainment of dust due to wet cleaning.
Provide stable operation even with high moisture content.
Support global emission compliance standards.
A Wet ESP is the most reliable and energy-efficient solution for achieving ultra-low particulate emissions.

How Does a Wet Electrostatic Precipitator Work?
Gas Inlet: Polluted gas enters the WESP.
Ionization Zone: High-voltage electrodes create an electrical field that charges fine particles and aerosols.
Collection Zone: Charged particles migrate to collecting tubes or plates.
Water Film Rinsing: Continuous flushing removes captured pollutants, preventing buildup.
Clean Gas Outlet: Clean, moisture-neutralized gas exits the system.
WESP works effectively even with high humidity, corrosive compounds, and sticky pollutants.
