A Dry Electrostatic Precipitator (ESP) is an air pollution control device that removes particles from a gas stream using the force of an electrostatic charge. The device is designed to handle high-volume exhaust streams from industrial processes, such as power plants, cement plants, and steel mills, among others.
How does it work?
The process starts with an ionizer that charges the incoming gas stream with high voltage electrodes. The charged particles then move towards a collection electrode, which has an opposite charge to attract the particles. The collected particles are then removed from the electrode and collected in a hopper. The clean gas then exits through the outlet.
Benefits of Dry Electrostatic Precipitator:
1. Highly efficient at removing submicron particles from the gas stream.
2. Low operating costs as it doesn't require any consumables like filter bags.
3. Able to handle high-volume gas streams and operate at high temperatures.
4. Can be retrofitted to an existing system or designed as a standalone unit.
Applications:
1. Power plants
2. Cement plants
3. Steel mills
4. Chemical plants
5. Paper mills
6. Textile mills
7. Waste-to-energy plants
Dry Electrostatic Precipitator is a reliable and cost-effective air pollution control device that helps industries meet environmental regulations by reducing emissions of particulate matter.
