The Electrostatic Precipitator (ESP) is a highly efficient environmental protection device used in a wide range of industrial processes, designed to help industries comply with increasingly stringent environmental regulations by effectively capturing dust particles in the exhaust air using advanced electrostatic cleaning technology, thereby significantly reducing dust emissions. The core operating principle is based on two key systems: the discharge electrode and the collector electrode. When the industrial exhaust gas enters the ESP, the discharge electrode releases a large number of high-energy electrons that ionise and charge the dust particles in the exhaust gas. Under the action of the electric field force, the charged dust particles migrate towards the collector electrode and eventually settle on the electrode surface, separating from the gas as the purified clean air is discharged into the atmosphere by the induced draft fan.
The electrostatic precipitator is the preferred technology for handling highly polluted gases. Based on the principle of high-voltage electrostatic field adsorption, it can efficiently collect ultra-fine dust particles as small as 0.1 micron, and the collection rate of PM2.5 and PM10 is stable at more than 99.8%, which is superior to traditional mechanical dust collectors.
Its intelligent power management system reduces the unit's energy consumption by 30% at full load compared to similar technologies, and the modular pole plate design extends the maintenance interval to 8,000 hours, saving 40% on operating costs. The fully sealed galvanised steel frame and ceramic insulated components ensure stable operation for more than 10 years in high temperature (≤400℃), high humidity (≤80%RH) and corrosive gas environments. The technology has been applied to more than 20 heavy industrial scenarios, controlling dust emission concentration within 5mg/Nm³, meeting relevant emission standards, helping companies achieve the goal of ecological improvement and building a sustainable industrial exhaust gas management system.
