ESP/WESP
Introduction Electrostatic precipitator (ESP) is a kind of dust removal equipment in which dust particles are ionized by high voltage electric field and charged by dust particles. Under the action of electric field force, dust particles are deposited on the electrode, so that dust particles and dust gases are separated. It can effectively recover the dust in the gas to purify the gas. The dust removal efficiency can reach 99% or even higher under suitable conditions. At present, it has been widely used in chemical industry, thermal power generation, cement, metallurgy, paper making and electronics, etc.
ESP Working principle
Electrostatic precipitator (ESP) is an electrical system which uses high voltage static electricity to separate solid and particles suspended in liquid from gas.
When the dusty gas passes through the channel between the two electrodes, the electrons and positive and negative ions in the corona current will be absorbed to the dust particles at a very fast speed, making the dust particles charged. Under the action of electric field force, the charged dust particles quickly move to the opposite direction of their polarity, and finally adsorb to the electrode and release charge. When the dust is deposited to a certain thickness, the dust layer is dropped into the lower ash hopper through the percussing of the vibration device, and the purified gas is discharged into the atmosphere through the air outlet, and the purification of the gas is completed. The dust removal process can be expressed as: ① Corona discharge →② Dust charge →③ Dust movement ④ Deposition and release →⑤ Dust cleaning.
