The coulomb force caused by the electric field causes the charged particles to be collected on the collecting plates and the gas is purified this is the principle of electrostatic precipitation and electrostatic precipitator applies this principle on an industrial scale.
The design of electrostatic precipitators has been mainly based on empirical knowledge of specialized manufacturers thanks to the advancements in computer technology and in physical processes description 1 it is now possible to conceive optimise and design an electrostatic precipitator by of use physical models.
The duct work leading to the precipitator has to have sufficient velocity to keep the particles from falling out of suspension and accumulating on the bottom of the duct when enough particles collect on surfaces it acts as insulation that can allow the surface of the metal to cool and condense water that can cause corrosion of the duct.
The electrostatic charge may increase the filters ability to capture certain particles these filters are disposable and do not fit into the hepa vs electrostatic comparison an electrostatic precipitator is a metal filter which has two stages the first stage is the ionizing section here are particles are given electrostatic charge.
