Wet Electrostatic Precipitator (WESP) for Kiln Plants

Product Overview

Our wet electrostatic precipitator for kiln plants is a customized WESP system designed for industrial kiln flue gas treatment. It can be applied to rotary kilns, shaft kilns, tunnel kilns, lime kilns, ceramic kilns and other high-temperature process exhaust streams. The equipment is typically installed after cyclone separators, bag filters, spray towers, scrubbers or desulfurization systems to perform terminal deep purification of wet flue gas. It helps kiln plants control fine particulate matter, PM2.5, acid mist, water droplets, aerosols and visible plume, supporting stricter emission compliance and cleaner production.

The equipment adopts high-voltage electrostatic adsorption combined with wet flushing. Fine particles, acid mist and aerosols 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, corrosive and fluctuating flue gas conditions commonly found in kiln exhaust treatment.

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, aerosols and fine kiln dust 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.

• Deep polishing after pretreatment: When arranged after a bag filter, spray tower, scrubber or desulfurization system, the WESP further removes residual fine particles, mist droplets and aerosols from wet kiln flue gas.

Key Features

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

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

• Strong adaptability to kiln flue gas: suitable for rotary kilns, shaft kilns, tunnel kilns and other kiln exhaust with high moisture, corrosive components and fluctuating working conditions.

• 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 dust removal, desulfurization and waste gas treatment systems.

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

Typical Applications

• Rotary kiln, shaft kiln and tunnel kiln flue gas treatment

• Lime kiln, ceramic kiln and other industrial kiln exhaust purification

• Deep purification after bag filter, cyclone separator, spray tower or desulfurization system

• Removal of PM2.5, acid mist, droplets, aerosols and visible plume

• Terminal polishing for kiln plant environmental upgrading projects
