Industrial Electrostatic Precipitator Filter Factory

An electrostatic precipitator is a device that uses electrostatic force to remove suspended particles in the air such as flue gas and industrial dust. It mainly consists of a discharge electrode and a collector. After high-voltage direct current is passed through the discharge electrode and a strong electric field is created around it, the particles in the air are charged. Each dust particle obtains the same negative charge through ionization. Based on the principle of attraction between opposite charges, the charged dust particles are attracted to the grounded collector, thereby achieving dust collection. The dust collected on the collector is collected into the ash hopper at the bottom through regular vibration or ultrasonic methods.

Electrostatic Precipitator INDUSTRY KNOWLEDGE

Electrostatic Precipitator vs Bag Filter: Efficiency, Cost and Environmental Performance Comparison

1. Dust Removal Efficiency Comparison

Electrostatic Precipitator (ESP):
Suitable for high-concentration, large flue gas volume dust removal (such as coal-fired power plants, steel sintering, etc.), with collection efficiency for fine particles (PM2.5) reaching over 99%. However, its performance is sensitive to dust resistivity (both too high or too low resistivity affects efficiency).

Bag Filter:
Provides higher filtration efficiency for ultrafine dust (such as in cement, pharmaceutical industries, typically >99.9%), and is not limited by dust resistivity. However, it requires regular bag replacement, and long-term operational stability depends on maintenance level.

Anhui Tiankang can customize solutions according to working conditions. For example, in steel industry applications with high-humidity flue gas, it adopts anti-condensation filter bags + pre-coating technology to improve bag filter stability; in power industry applications, it optimizes ESP plate layout to handle high-resistivity dust.

2. Cost Comparison

Initial Investment:
ESP typically has higher initial costs than bag filters due to its high-voltage power supply system and large steel structure, but it's more suitable for high-temperature flue gas (above 400°C).

Operation and Maintenance Costs:
Bag replacement (especially in corrosive conditions) is the main expense for industrial electrostatic precipitator filters, while ESP has higher power consumption (especially when needing humidity conditioning for high-resistivity dust).

Anhui Tiankang provides life-cycle cost optimization solutions, such as using membrane-coated filter bags in cement plants to extend service life, or equipping ESP with intelligent high-voltage power supplies to reduce power consumption.

3. Environmental Performance and Adaptability

Emission Standards:
Bag filters can more easily meet ultra-low emission standards (such as <10mg/m³), while ESP performs better in collaborative treatment (such as post desulfurization and denitrification flue gas).

Complex Working Conditions:
ESP has stronger resistance to high temperatures and corrosion, making it suitable for applications like steel sintering machine heads; industrial electrostatic precipitator filters require special filter materials when handling oily mist or sticky dust (such as biomass combustion).

Anhui Tiankang's VOC treatment systems (such as RTO, activated carbon adsorption) can be designed in coordination with dust removal equipment to achieve integrated treatment of multiple pollutants.
