Different types of electrostatic precipitator systems have been around for over 100 years, but how does an electrostatic precipitator work?
ESP dust collectors–AKA Electrostatic Precipitators–use electricity to create an electrostatic force that separates dust from the air or exhaust gas flowing through it.
Parts of an Electrostatic Precipitator
All electrostatic precipitators have three main parts:
- Power Supply – Provides a high voltage electric current for the unit to create a negative electrostatic charge for the particles in the exhaust stream that can then be collected by the positively charged collection plates.
- Charged Electric Surfaces – These are a series of wires or rods (negative) and collector plates or panels (positive) that are electrostatically charged during the collection process and attract dust and other particulate matter to them.
- Collection Apparatus – These are usually the collector plates themselves where the dust can be removed, cleaned and reused in the electrostatic precipitators, or may be a disposable filter used to collect the particles as they are attracted to the metal plate behind it.
Electrostatic Process
The contaminated air flows into the electrostatic precipitator, and flows through an area where the power supply has created a strong electrostatic field by applying a high-voltage negative-charged current near the opening of the air flow–typically in the form of wires, or thin metal rods, causing the dust particles that flow through to gain a negative charge.
The air then flows through a series of collection plates to which the power supply has created a strong positive charge. The negatively charged particles are attracted to the positively charged plates and get lodged there.
This process continues until there is a need to clean the collection plates from all of the accumulated grime and other contaminants, or replace the media filters that capture the negatively charged dust particles.
Why Smog-Hog Electrostatic Precipitators Are Superior
The ESP technology used in Smog-Hog brand electrostatic precipitators and mist collectors have superior ESP efficiency. These units create an extremely high rate of particle removal efficiency for submicronic particulates–those smaller than 1 µm (micrometres). A single pass of a Smog-Hog ESP removes 95% particles as small as .3 µm, and 97% of those that pass through the system twice.
