Product introduction: wet electrostatic precipitator is an electrostatic precipitator that forms a layer of water film on the surface by spraying water or overflow water to realize ash removal. Wet dust removal can avoid the re flying of settled dust and achieve high dust removal efficiency. Because there is no rapping device, the operation is stable, but there are problems of corrosion, sludge and sewage treatment. It is not as widely used as dry electrostatic precipitator. Electrostatic precipitator is a dust collector that uses electrostatic force (Coulomb force) to separate particles from air flow. There are plate type and tube type, horizontal flow type and vertical flow type, dry type and wet type. During operation, there are three main steps: charging suspended particles, trapping charged particles in the electric field, and removing particles trapped on the dust collecting plate. It is characterized by small air flow resistance, can handle high-temperature gas, and the dust removal efficiency can reach 99%. It is not affected by the moisture contained in dust particles. It is suitable for handling low dust concentration and dust particle size of 0.05-50 μ M, but the investment and maintenance cost are high, the floor area is large, and the electrical properties of multi particles have an impact on the dust removal efficiency. It is mainly used to deal with occasions with large amount of flue gas.
