The structure and classification of wet electrostatic precipitator

      Wet electrostatic precipitators have several structural forms. One is to use corrosion-resistant conductive materials (which can be non-metallic materials with excellent conductivity or metal materials with corrosion resistance) as the dust collector, and the other is to use water spray Or non-metallic materials that form a conductive water film and do not conduct electricity are used as dust collectors by overflowing water.

      Wet electrostatic precipitators can also be divided into cross flow (horizontal) and vertical flow (vertical). The cross flow is mostly plate structure, and the gas flow direction is horizontal direction. The structure is similar to dry electrostatic precipitator; the vertical flow type is mostly Tubular mechanism, the gas flow direction is vertical direction. Generally speaking, the efficiency of vertical flow type wet electrostatic precipitator is twice that of cross flow type under the same ventilation cross-sectional area.

      The dust collected on the electrode plate can be washed down with water. Wet cleaning can prevent the collected dust from flying again and achieve high dust removal efficiency. Because there is no rapping device, the operation is also more reliable. The device that uses water spray or overflow water to form a conductive film on the surface of the dust collector has problems with corrosion, sludge and sewage treatment. It is only used when the gas dust concentration is low; the dust efficiency is required to be higher; use; The wet electrostatic precipitator with corrosion-resistant conductive material as the dust collecting electrode does not require long-term water spraying or overflow water, and only periodically flushes according to the system operation status, and only consumes a very small amount of water. This part of the water can be recycled and reused. The dust collection system is basically No secondary pollution.
