What is the principle of electrostatic precipitator?
Electrostatic precipitators operate on the principle of the attraction of a charged particle for an oppositely charged collector. They have been used for both collecting particles for further analysis and for controlling particulate emissions from sources.
What is the importance of electrostatic precipitator?
An electrostatic precipitator (ESP) is defined as a filtration device that is used to remove fine particles like smoke and fine dust from the flowing gas. It is the commonly used device for air pollution control. They are used in industries like steel plants, thermal energy plants.
Who discovered electrostatic precipitator?
Frederick Cottrell invented the “electrostatic precipitator,” which removes pollutants from smoke. Cottrell was born on January 10, 1877, in Oakland, California, the son of Henry and Cynthia Cottrell. His ingenuity and interest in the applied sciences were demonstrated early on.

Where is electrostatic precipitator used?
Originally designed for recovery of valuable industrial-process materials, electrostatic precipitators are used for air pollution control, particularly for removing harmful particulate matter from waste gases at industrial facilities and power-generating stations.
How does electrostatic precipitator help the environment?
Electrostatic precipitators are used for the removal of particulate matter from the polluted air. Different types of particulate matter include dust, smoke, soot, ashes, and fumes. Precipitators give a control efficiency of 99% for particulate matter that is ≥1.0 μm in diameter.
What are the applications of electro static precipitators in various industries?
Electrostatic Precipitators are used in steam plants for removing the dust from flue gases. Electrostatic Precipitators are used in machine shops and chemical plants for removing oil mists and acid mists. ESPs are used to remove the bacteria & fungus in the medical field.

What is a precipitator definition?
Precipitator definition One who precipitates, or urges on with vehemence or rashness. noun. A person who, or device that, carries out precipitation. noun. An apparatus which removes dust particles from gases by electrostatic precipitation.
What are the parts of ESP?
The main components of an ESP consist of collecting electrodes/plates, discharge electrodes, inlet and outlet perforated screens, insulators for the discharge electrodes, rappers, and one or more electrical transformers.

Electrostatic Precipitators Information
| Advantages | Disadvantages |
|---|---|
| Handles very large gas volumes and heavy dust loads with low pressure drop. | Not very flexible to changes in operating conditions once installed/purchased. |
| Very high collection efficiencies, even for very small particles. | Cannot control gaseous emissions |
