Wet Electrostatic Precipitator  (WESP) for Heating Industry

Product Overview

Our wet electrostatic precipitator for the heating industry is a customized WESP system designed for coal-fired boilers, biomass boilers, gas-fired boilers and other heating furnace flue gas. It is usually installed after bag filters, cyclone dust collectors, spray towers or desulfurization systems to perform deep purification of wet flue gas. The system can effectively remove fine particulate matter, PM2.5, acid mist, water droplets, aerosols and visible plume, helping heating plants and district heating stations achieve stable particulate emission control.

The equipment adopts high-voltage electrostatic adsorption combined with wet flushing. Dust and mist particles are charged in the electric field, captured on the collecting electrode surface, and then washed away by circulating water. This wet cleaning method avoids mechanical rapping and reduces the risk of secondary dust emission, making it especially suitable for high-humidity, high-load and winter continuous-operation conditions commonly found in heating boiler systems.

How It Works

• Gas ionization and particle charging: High-voltage DC power generates a strong electric field between the anode tubes and cathode wires, causing gas ionization and particle charging.

• Fine particle and mist collection: Charged PM2.5, acid mist, droplets and aerosols migrate to the collecting electrode and are captured on the electrode surface.

• Wet flushing cleaning: The flushing system forms a continuous water film to wash captured pollutants into the drain, preventing ash accumulation and secondary dust.

• Terminal polishing after desulfurization: When arranged after a desulfurization tower or spray tower, the WESP further removes residual fine particles, mist droplets and aerosols from saturated wet flue gas.

Key Features

• High removal efficiency for fine particles: effectively captures PM2.5, submicron particles, acid mist, droplets and aerosols from heating boiler flue gas.

• No secondary dust emission: wet flushing replaces mechanical rapping, improving outlet cleanliness and operational stability.

• Strong adaptability to heating boiler flue gas: suitable for coal-fired, biomass and gas-fired heating systems with high moisture, fluctuating load and long winter operating hours.

• Stainless steel anode tube modules: anode modules, shell and internal components can be made from stainless steel or other corrosion-resistant materials according to flue gas properties.

• Flexible structural layout: available in vertical or horizontal type, with circular or square shell, and can be integrated with existing boiler dust removal and desulfurization systems.

• Customized engineering supply: configured according to actual air volume, temperature, humidity, dust load and emission requirements.
