The high-voltage electrostatic wet dust collector uses high-voltage pulse direct current and electric field to drive the fine dust in the flue gas to accelerate its settlement on the anode surface to remove the dust particles in the flue gas. It is a device that captures and purifies the residual droplets and dust after filtering by the mechanical dust collector of the absorption tower.

Introducing 0~80 kV (adjustable) high-voltage pulse direct current into the device, so that the corona electrode suspended in the device continuously emits electrons, ionizing part of the gas between the electrodes into positive and negative ions, and particles such as dust and dust are charged by touching ions. According to the principle of same-sex repulsion and opposite-sex attraction, the charged dust particles move in the opposite direction of electric polarity and positive ions move to the corona electrode, the electrons and negative ions move to the precipitation electrode. Dust dispersed in the gas collides with negatively charged ions and is charged. Under the action of the electric field, the charged dust particles move to the inner wall of the precipitation pole, fall down along the wall by their own weight, fall into the dust collection device below the electrostatic precipitator and mix with the slurry, so that the discharged flue gas is purified and meets the national emission standards.
