What is meant by 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.
What is the purpose of an electrostatic precipitator?
Description. An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively.
What are the types of electrostatic precipitator?
There are four basic types of ESPs: plate and wire (dry), flat plate (dry), wet, and two-stage. ESPs provide a large air volume, operate favourably in various temperatures, and require little maintenance.
What is the principle of electrostatic precipitator?
The working principle of the electrostatic precipitator is quite simple. It has two sets of electrodes one is positive, and another is negative. The negative electrodes are in the form of a rod or wire mesh. Positive electrodes are in the form of plates.
How much is an electrostatic precipitator?
Cost Effectiveness: $73 to $720 per metric ton ($65 to $660 per ton) Theory of Operation: An ESP is a particulate control device that uses electrical forces to move particles entrained within an exhaust stream onto collection surfaces.
How do you create an electrostatic charge?
Static electricity can be created by rubbing one object against another object. This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge.
Are electrostatic precipitators expensive?
Electrostatic precipitators have a high initial capital cost, which makes it prohibitive for small-scale industries. They are expensive to purchase and install. In addition to being costly, they require large space to be set up.
What are the advantages of electrostatic instrument?
Advantages of Electrostatic Instrument Both the AC and DC voltage can be measured by using the electrostatic instrument. The electrostatic type instrument consumes very less power. The high value of voltage can be measured by using the instrument.
