Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of waste gas purification, specifically to a wet type electric dust collector. BACKGROUND

[0002] The wet type electric dust collector is a kind of high-efficiency purification equipment, mainly used for treating the gas containing trace dust and micro-particles, such as removing dust, acid mist, water droplets, aerosol and other harmful substances in the gas containing moisture, which uses high-voltage electrostatic field to make the dust in flue gas charged and adsorbed on the electrode, and then cleaned by the water spraying system.

[0003] When cleaning the dust adsorbed on the electrode plate, the relatively fine dust will still adhere to the electrode plate due to moisture and other reasons, which will cause the efficiency and effect of the electrode plate to absorb dust to decrease significantly over a long period of time.
