What are the components of electrostatic precipitator?
An ESP is primarily made up of the following four components: gas distribution plates, discharge electrodes, collection surfaces (either plates or pipes) and rappers. The gas distribution plates consist of several perforated plates which help maintain proper flow distribution of the entering gas stream.
What is electrostatic precipitator PDF?
The electrostatic precipitator {ESP) uses electrical forces to capture either liquid or solid particles from a gas stream.
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.
How electrostatic precipitator works its parts and applications?
Electrostatic smoke precipitators work by forcing dirty flue gas (the gas escaping from a smokestack) past two electrodes (electrical terminals), which take the form of metal wires, bars, or plates inside a pipe or smokestack. The first electrode is charged to a very high negative voltage.
What is the working principle of ESP?
Basic Principle of ESP A high voltage is applied to the discharge electrode, generating a corona discharge that produces minus ions. The electrically charged dust is accumulated on the collecting electrode by an electrical field.
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.
Why is ESP used?
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 working principle of electrostatic precipitator?
What is corona in electrostatic precipitator?
Back corona, the migration of positive ions generated in the fly ash layer towards the emitting electrodes, which neutralize the negatively charged particles, will result if the ash resistivity is greater than 1012Ωcm.
What are the advantages of ESP?
Advantages of electrostatic precipitator:
- The durability of the ESP is high.
- It can be used for the collection of both dry and wet impurities.
- It has low operating costs.
- The collection efficiency of the device is high even for small particles.
- It can handle large gas volumes and heavy dust loads at low pressures.
