Honeycomb Electric Tar Precipitator

Product Overview

A honeycomb electric tar precipitator is a high-voltage electrostatic separation device that uses a honeycomb-type collecting electrode structure to remove tar mist, oil mist, asphalt smoke, fine particulate matter and condensable pollutants from industrial gas streams. Compared with concentric-circle and tubular electric tar precipitators, the honeycomb structure provides a more uniform electric field, higher specific collection area and more compact layout, making it especially suitable for high-efficiency tar removal from coke oven gas, coal gas, biomass gasification gas, carbon plant exhaust and asphalt fume streams.

The equipment is typically installed after gas cooling, condensation, cyclone separation, spray towers or other pretreatment units. It can also be arranged upstream of absorption towers, RTO systems, catalytic combustion units or downstream emission control systems. By combining high-voltage corona charging with gravity drainage or wet flushing, the honeycomb electric tar precipitator helps reduce tar mist carryover, protect downstream equipment, improve gas quality and support stable long-term operation.

How It Works

• High-voltage corona charging: A high-voltage DC power supply generates a strong electrostatic field between the discharge electrodes and honeycomb collecting electrodes.

• Tar mist and aerosol charging: Tar droplets, oil mist, asphalt smoke and fine particles capture ions and become electrically charged.

• Honeycomb electrostatic collection: Charged pollutants migrate to the inner surface of the honeycomb channels under electrostatic force and are captured on the electrode wall.

• Drainage or flushing removal: Collected tar flows down by gravity into a bottom tank, or is washed away by a flushing system to prevent electrode fouling and maintain stable voltage.

Key Features

• Compact honeycomb electrostatic field: hexagonal channels provide high specific collection area and uniform field distribution.

• High tar mist removal efficiency: effectively captures submicron tar mist, oil mist, asphalt smoke and fine aerosols.

• Low pressure drop: straight-through honeycomb channels reduce flow resistance and fan energy consumption.

• Stainless steel electrode modules: honeycomb collecting electrodes, discharge wires and internal components can be made from stainless steel or other corrosion-resistant materials.

• Dry or wet cleaning options: supports gravity drainage, steam cleaning, water flushing or automatic cleaning according to tar viscosity and process conditions.

• Customized engineering design: configured based on gas volume, temperature, tar concentration, moisture content, oxygen level and installation space.

Typical Applications

• Coke oven gas and coal gas tar mist removal in coking and coal chemical plants

• Carbon plant and carbon black plant asphalt fume treatment

• Rubber pyrolysis, tire recycling and rubber vulcanization exhaust treatment

• Biomass gasification, wood carbonization and pyrolysis gas cleaning

• Asphalt mixing plants and waterproofing material production exhaust

• Ceramic kiln and industrial furnace oily fume treatment

• Gas purification before RTO, catalytic combustion, absorption towers or downstream emission control systems

• Removal of tar mist, oil mist, asphalt smoke, PM2.5 and condensable organic aerosols

FAQ

Why choose a honeycomb structure instead of tubular or concentric-circle types?
Honeycomb channels provide a more uniform electric field, higher space utilization and larger specific collection area, which helps improve tar mist removal efficiency and reduce equipment footprint.

Can it be used for high-viscosity tar or asphalt smoke?
Yes. For high-viscosity tar, asphalt smoke or oily mist, the unit can be designed with heating insulation, flushing systems or automatic cleaning structures to reduce fouling risk.

What materials are used?
Honeycomb collecting electrodes, discharge wires and internal components can be made from stainless steel or other corrosion-resistant materials based on gas composition and customer requirements.

Is it available in vertical or horizontal layouts?
Yes. It can be supplied in vertical or horizontal structure, with circular or square shell, and can be customized according to site conditions and process requirements.
