Wet Electrostatic Precipitator  (WESP) for Rock Wool Plants

Product Overview

Our wet electrostatic precipitator for rock wool plants is a customized WESP system designed for rock wool and mineral wool production lines. It can be applied to cupola or melting furnace exhaust, fiber collection exhaust, curing oven exhaust and related process gas streams. The equipment is typically installed after cyclone separators, bag filters, spray towers or desulfurization systems to perform terminal deep purification of wet flue gas. It helps rock wool plants control fine mineral fiber dust, PM2.5, acid mist, water droplets, aerosols and visible plume, supporting cleaner production and stricter particulate emission control.

The equipment adopts high-voltage electrostatic adsorption combined with wet flushing. Fine particles and mist droplets 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, fine-fiber and fluctuating exhaust conditions commonly found in rock wool melting, fiberizing and curing 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 fiber dust and mist collection: Charged mineral fiber dust, 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 fiber accumulation and secondary dust.

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

Key Features

• High removal efficiency for fine mineral fiber dust: effectively captures PM2.5, submicron particles, acid mist, droplets and aerosols from rock wool production exhaust.

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

• Strong adaptability to rock wool flue gas: suitable for cupola, melting furnace, fiber collection and curing oven exhaust with high moisture 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

• Cupola and melting furnace exhaust treatment in rock wool plants
