Know More About The Dust Collection Efficiency Of Electrostatic Precipitators

For someone not aware of the term yet, electrostatic precipitator is basically the process through which electrostatic forces are used to collect dust. These electrostatic forces generally comprise of collecting plates and discharge wires. An electrical field is created when a high voltage is applied to the discharge wires. Ions are also supplied as the gas around the wire also get ionised.  Though being quite complicated, the principal of Electrostatic Precipitation is applied on an industrial scale.

ESP at a industry

Since the device has so much to offer, make sure that the supplier you are approaching for durable and efficient electrostatic precipitators is indeed reliable. This will give you the assurance that the Electrostatic Precipitator Spares offered by them are of the highest quality and the device can last for years to come even with minimal maintenance. Their professionals are also aware of all the factors on which the dust collection efficiency of the device depends.

3 Factors On Which The Dust Collection Efficiency Of An Electrostatic Precipitator Depends

  • Electrical Resistivity Of Dust

The normal the resistivity area will be, the higher will be the dust collection efficiency of the device and the process will be more stable. On the other hand, particles have a higher chance of losing their charge on their arrival at the collecting plate if they are in some low-resistivity area. This means that the particles again enter the dust collection area and the efficiency of the device reduces. Even in a high-resistivity area, its dust collection efficiency reduces with an increase in the electrical resistivity of the dust. This is why you need to consider the electrical resistivity of the dust when determining the right model of the electrostatic precipitator or its spares.

  • Particle Size Distribution

The particle size of the aerosol you are willing to collect in the electrostatic precipitator also determines its dust collection efficiency. When performed on aerosol with particles of different sizes, the collection efficiency of the large particles will be higher while that of the small particles will be lower. You need to consider the size of both the aerosol and the device if you want to get specific dust collection efficiency. Using a bigger device means the treating time will increase and so the process gas will take more time to pass through it.

  • Concentration Of Aerosol

Since the aerosol comprises of both dust and mist, the concentration of gas in it also differs. The dust collection efficiency of the device is largely dependent on the aerosol concentration. If you want the value of aerosol concentration to remain the same at the outlet of the device, the aerosol concentration should be higher at the inlet. Sometimes, its dust collection efficiency can reduce inspite of the aerosol concentration being higher at the inlet if the sizes of the particles are small.

Since you are now aware of the prime factors determining the efficiency of an electrostatic precipitator, it’s time you start looking for a reliable company offering the device and its spare parts at affordable prices.
