What is an Electrostatic Precipitator (ESP)? Definition

Aug 28, 2014· An electrostatic precipitator (ESP) is a device which removes dust or other finely divided particles from a gas by charging the particles inductively with an electric field, then attracting them to highly charged collector plates. Electrostatic precipitators are large boxlike structures, typically containing hundreds of plates.

Electrostatic precipitator pollution-control device

Electrostatic precipitation is a commonly used method for removing fine particulates from airstreams. In an electrostatic precipitator, particles suspended in the airstream are given an electric charge as they enter the unit and are then removed by the influence of an electric field. The

What Is An Electrostatic Precipitator and How Does It

At its most basic, an electrostatic precipitator is an air purification tool that uses electrostatic force to grab and hold dust and other particles. It consists primarily of wires and collection plates, with a high voltage applied from an electrostatic field between the wires and the collecting plate, charging the air electrically and ionizing

Electrostatic Precipitator an overview ScienceDirect

The process of trapping particulate matter by electrostatic precipitator includes four steps: (1) negative high-voltage discharge, flue gas ionization, generation of negative ions; (2) fly ash is charged by electric field and negative ions; (3) charged fly ash is collected to the anode plate; (4) after rapping, the fly ash on the anode plate

electrostatic precipitator Particles of high electrical resistivity lose their charge slowly after hitting the collecting plate. This creates an electrical shield on the plates that lowers the ambient electric field. As a result, particles of high electrical resistivity drift more slowly and are harder to collect.

Advantages and Disadvantages of Electrostatic Precipitator

Oct 28, 2020· Electrostatic precipitator uses the high-intensity electric field to ionise the dust particles in the air stream and then the dust particles are collected by oppositely charged collectors (electrodes). The dust particles, once collected are removed from the collector plates periodically by hammering the collectors by a different mechanism.

Electric field in an electrostatic precipitator. Physics

Sep 17, 2011· Smoke enters the precipitator at the bottom, ash and dust in it pick up electrons, and the charged pollutants are accelerated toward the outer cylinder wall by the electric field. Suppose the radius of the central wire is 83*10^(-6) m, the radius of the cylinder is 14.0 cm, and a potential difference of 50.0 kV is established between the wire
