Wet Electrostatic Precipitator for Chemical Plants

Product Overview

Our wet electrostatic precipitator for chemical plants is a customized WESP system designed for chemical process exhaust, reaction vent gas, acid/alkali wash tail gas, drying and evaporation exhaust, and wet flue gas after scrubbers or absorption towers. It is widely used in fine chemicals, petrochemicals, fertilizer, pesticide, pharmaceutical intermediates, lithium battery materials, titanium dioxide, acid washing and related chemical processes. The equipment is typically installed after spray towers, scrubbers, condensers, cyclone separators or wet desulfurization systems to perform terminal deep purification of high-humidity, corrosive and sticky exhaust.

Chemical exhaust often contains acid mist, alkali mist, submicron particles, aerosols, droplets, soluble salts and condensable pollutants. These components are difficult to remove completely by conventional dry dust collectors or simple washing towers. The WESP uses high-voltage electrostatic charging combined with wet flushing to capture fine mist and particles on the collecting electrode surface, then washes them away with circulating water. This wet cleaning method avoids mechanical rapping, reduces secondary dust emission and helps downstream treatment systems operate more stably.

How It Works

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

• Acid mist, alkali mist and aerosol collection: Charged acid mist, alkali mist, PM2.5, aerosols, droplets and fine particles 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 crystallization, tar-like buildup and secondary dust.

• Terminal polishing after chemical pretreatment: When arranged after scrubbers, spray towers, condensers or absorption systems, the WESP further removes residual fine mist, aerosols and particulate matter from chemical exhaust.

Key Features

• High removal efficiency for chemical aerosols: effectively captures acid mist, alkali mist, PM2.5, submicron particles, aerosols, droplets and condensable pollutants.

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

• Strong adaptability to corrosive chemical exhaust: suitable for high-humidity, saturated and corrosive flue gas commonly found in chemical processes.

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

• Flexible structural layout: available in vertical or horizontal type, with circular or square shell, and can be integrated with existing scrubbers, absorption towers and VOC treatment systems.

• Customized engineering supply: configured according to actual air volume, temperature, humidity, acid/alkali content, mist load, installation space and emission requirements.

Typical Applications

• Fine chemical, petrochemical and pesticide process exhaust treatment

• Fertilizer, pharmaceutical intermediate and lithium battery material production exhaust polishing
