The spiral umbrella high-voltage electrostatic precipitator is a secondary dust removal equipment used in cement industry dryers, suitable for dust removal of clay, coal, iron powder, slag, etc. It is composed of four vertical metal cylindrical bodies as the main part of electrostatic dust collection. The inner wall of the cylinder is equipped with multiple umbrella shaped dust collection electrodes without a top, and the center of the cylinder is equipped with a spiky corona wire. A spring protection device is installed at the connection between the corona wire and the lower part. This structure of the dust collector does not produce secondary dust, and the dust collection efficiency reaches99.8%And it has a long service life and good dust collection effect.
The spiral umbrella high-voltage electrostatic precipitator is used to separate particulate dust and fine dust from industrial waste gas, and is widely used in metallurgy, mining, cement, thermal power plants, building materials, casting, chemical industry, tobacco, asphalt mixers, grain, mechanical processing, boiler dust removal, cement raw materials, clinker mills, cupolas, etc.
