HWES Series Industrial Horizontal Electrostatic Precipitator
High-Capacity Gas Cleansing & Fine Particulate Control
Engineered for extreme thermal environments and heavy dust loads, the HWES Series Dry Electrostatic Precipitator utilizes high-voltage ionization to isolate airborne dust, smoke, and hazardous particulate matter from industrial flue gases. By replacing physical filter media with electrostatic charging plates and mechanical rapping mechanisms, the system operates continuously without consumable replacement costs or system airflow resistance.
Core Capabilities
High-Temperature Operation: Thermally engineered casing and high-tensile alloy electrodes withstand continuous flue gas temperatures up to 450°C (customizable up to 650°C).
Low Resistance & Energy Efficiency: Operates with a minimal system pressure drop of 150–350 Pa, significantly reducing draft fan energy requirements.
Environmental Compliance: Achieves 99.5% to 99.95% filtration efficiency, maintaining clean air discharge levels at ≤ 30 mg/Nm³.
Zero Filter Maintenance: Automatic mechanical hammer-rapping dislodges accumulated dust into collection hoppers without process interruption.

Working Mechanism
Particle Charging: In particle charging process Dust laden gas enters the ESP horizontally and passes through discharge electrodes where particles are electrically charged.
Particle Collection: Here in this process those charged particles migrate toward the collecting plates due to electrostatic attraction.
Dust Removal: The collected dust is periodically removed by the rapper mechanism, dropping into hoppers.
Clean Gas Discharge: Clean air exits the system through an outlet duct, meeting stringent emission norms.
