Wet Electrostatic Precipitator (WESP) for Steel Plants

Product Overview

Our wet electrostatic precipitator for steel plants is a customized WESP system designed for ironmaking, steelmaking, rolling and auxiliary process exhaust treatment. It can be applied to sintering machine flue gas, pelletizing roasting exhaust, converter gas cleaning, electric arc furnace fume control, rolling mill oil mist exhaust, and downstream wet flue gas after bag filters, spray towers, scrubbers or desulfurization systems. The equipment is typically installed after primary dust removal or wet treatment units to perform terminal deep purification of wet process exhaust. It helps steel plants control PM2.5, acid mist, tar mist, metal fume, water droplets, aerosols and visible plume, supporting ultra-low emission and cleaner production requirements.

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 sticky exhaust conditions commonly found in sintering, pelletizing, converter and rolling mill processes.

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, tar mist, metal fume, 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 salt accumulation, tar adhesion 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 steel plant exhaust.

Key Features

• High removal efficiency for fine steel plant aerosols: effectively captures PM2.5, submicron particles, acid mist, tar mist, metal fume, droplets and aerosols.

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

• Strong adaptability to complex steel plant exhaust: suitable for sintering, pelletizing, converter, EAF and rolling mill 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/mist load and emission requirements.
