What Is A Precipitator Used For?

Description. 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.

Where do we use electrostatic precipitator?

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.

What is ESP pollution? 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 type of appliances use electrostatic precipitator?

An electrostatic precipitator is a type of filter (dry scrubber) that uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks. This one common air pollution control device. Most power stations burn fossil fuels such as coal or oil to generate electricity for use.

How does an electrostatic precipitator reduce 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.

How much does an electrostatic precipitator cost?

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.

What does an electrostatic precipitator remove?

Description. 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 corona ESP?

An electric field is established between the discharge and collecting electrodes, and the discharge electrodes will exhibit an active glow, or corona. As the flue gas passes through the electric field, the particulate takes on a negative charge. Corona on a high-voltage ESP wire. Collecting.

What is the working principle of ESP?

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 are the advantages and disadvantages of electrostatic precipitator?

AdvantagesDisadvantages
Very high collection efficiencies, even for very small particles.Cannot control gaseous emissions
Can handle corrosive materials, wet materials, and high temperatures.Very dependent on the electrical resistivity of the particulate.

Does an electrostatic precipitator work?

Electrostatic precipitators work in essentially the same way no matter what the details. As smoke and the gas stream is pumped out of a furnace or burner, it passes an initial wire or plate and gains the static charge. It is then collected by a second plate that has an opposite charge, where it is trapped.

What are the 3 types of electric charges?

What is a wet electrostatic precipitator?

A wet electrostatic precipitator (WESP) typically is used to control PM emissions in exhaust gas streams containing sticky, condensible hydrocarbon pollutants, or where the potential for explosion is high.

What are 10 ways to reduce pollution?

  1. Using public transports. …
  2. Turn off the lights when not in use. …
  3. Recycle and Reuse. …
  4. No to plastic bags. …
  5. Reduction of forest fires and smoking. …
  6. Use of fans instead of Air Conditioner. …
  7. Use filters for chimneys. …
  8. Avoid usage of crackers.

What is the highest source of outdoor air pollution?

The common sources of outdoor air pollution are emissions caused by combustion processes from motor vehicles, solid fuel burning and industry. Other pollution sources include smoke from bushfires, windblown dust, and biogenic emissions from vegetation (pollen and mould spores).

What is the need for pollution control?

Need for Pollution Control. Pollution prevention or control is needed to preserve precious environmental resources and to improve the environmental quality so that the preserved resources can be utilized for the benefit of mankind and the improvement of health and wellbeing of the people.
