The Wet Electrostatic Precipitator (WESP) is an advanced air pollution control device used primarily in power plants to remove fine particles, aerosols, and mist from the exhaust gas stream. In a coal-fired power plant, a WESP is often installed as the final polishing stage downstream of the scrubber (WFGD).
• High Efficiency: Capable of removing over 99% of fine particulate matter (PM2.5) and sub-micron aerosols.
• Handles Moisture: Ideal for saturate d gas streams where dry ESPs would fail.
• Removes Soluble Pollutants: Effectively captures acid mist (e.g., sulfuric acid), condensable hydrocarbons, and heavy metals (e.g., mercury).
• No Re-entrainment: The continuous water wash prevents collected particles from being blown back into the gas stream.
