Anode Tube Bundle for Electric Tar Precipitator

Product Overview

Our anode tube bundle for electric tar precipitators is a stainless steel honeycomb collecting electrode module used as the core precipitation component in electric tar precipitators and wet electrostatic precipitators. It is widely applied in coke oven gas purification, coal gas treatment, carbon and graphite production, rubber vulcanization exhaust, asphalt flue gas, biomass pyrolysis gas and chemical process gas containing tar mist, asphalt mist, oil mist and fine particulate matter.

The anode bundle consists of multiple hexagonal stainless steel tubes arranged in a honeycomb structure. Each hexagonal tube acts as a grounded collecting electrode, while a discharge electrode is suspended along its center axis. Under high-voltage DC electric field, tar mist droplets and fine particles become negatively charged and migrate to the anode tube wall, where they are collected, coalesced and drained by gravity. The wet flushing or hot liquid flushing system continuously washes the tube inner surface to prevent tar accumulation and maintain stable operation.

Structure & Working Principle

• Honeycomb hexagonal tube bundle: multiple positive hexagonal tubes are closely arranged to form a compact anode module with high space utilization and uniform electric field distribution.

• Grounded collecting electrode: the anode tube bundle is connected to ground and serves as the positive precipitation surface for tar mist, oil mist and fine particles.

• Cooperation with discharge electrode: each hexagonal tube contains a central discharge electrode, usually made of stainless steel, nickel-chromium alloy or titanium alloy wire, to generate corona discharge and charge pollutants.

• Wet flushing cleaning: circulating water, hot ammonia water or process liquid forms a continuous liquid film on the inner tube wall, washing collected tar and oil into the bottom collection tank.

Key Features

• High collection efficiency for tar mist and aerosols: effectively removes submicron tar droplets, asphalt mist, oil mist, PM2.5 and condensable pollutants.

• Honeycomb hexagonal structure: provides larger collection area per unit volume than round tubes and reduces electric field dead zones.

• Stainless steel material options: anode tubes can be made from SUS304, SUS316L, 2205 duplex stainless steel or other corrosion-resistant alloys according to gas composition.

• Smooth inner surface: polished tube walls facilitate liquid film formation, tar drainage and flushing cleaning, reducing fouling and blockage risk.

• Modular design: anode bundles are manufactured as complete modules with upper and lower support plates, flanges and reinforcement structures for easy installation and replacement.

• Customized manufacturing: tube size, bundle quantity, module length, material grade and connection structure can be configured according to gas volume, temperature, tar load and installation space.

Typical Applications

• Coke oven gas and coal gas tar mist removal

• Carbon, graphite and anode production exhaust treatment

• Rubber vulcanization and asphalt flue gas purification

• Biomass pyrolysis gas and wood tar mist separation

• Chemical process gas containing oil mist, tar mist or condensable aerosols

• Front-end tar interception before RTO, scrubber, adsorption or downstream treatment systems

FAQ

What is the function of the anode tube bundle in an electric tar precipitator?
It serves as the grounded collecting electrode. Charged tar mist, oil mist and fine particles migrate to the anode tube wall, are captured, coalesced and drained by gravity or flushing liquid.

What materials are used for anode tube bundles?
Common materials include SUS304, SUS316L and 2205 duplex stainless steel. Material selection depends on tar composition, chloride content, temperature and corrosion conditions.

What tube shape is commonly used?
Hexagonal honeycomb tubes are widely used because they provide higher space utilization, larger collection area and more uniform electric field distribution than round tubes.

Can the anode bundle be customized?
Yes. Tube diameter, length, wall thickness, module quantity, material grade and connection structure can be customized according to actual process conditions.
