Electrostatic precipitator

An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

What is an electrostatic precipitator and how does it work?

An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The charged particles are then attracted to collector plates carrying the opposite charge.

What is the function of electrostatic precipitator?

Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues.

How do electrostatic precipitators reduce air pollution?

The electrostatic precipitator works by removing particles and smoke from a gas stream using an electrostatic charge. ... Introducing a water spray can reduce the electrical resistance of the dust particles, allowing them to accept the charge more easily.

What industries use electrostatic precipitator?

Industrial electrostatic precipitators applications are used in the industry to control their particulate matter emissions: fossil fuel-fired boilers, cement plants, steel mills, petroleum refineries, municipal waste incinerators, hazardous waste incinerators, pulp and paper mills, and lead, zinc, and copper smelters.
