Tube type electric tar catcher: Due to the separate electric field formed by the steel pipe and corona wire, the field strength voltage depends on the radius of the steel pipe, with a value of 400R. As the tube type electric tar catcher forms an equidistant electric field in each tube section, there are empty spaces between tubes, which are blocked by blind spots on the tube plate. This reduces the utilization of space inside the cylinder and reduces the cross-sectional area of the purification channel. This type of electric tar catcher consumes a large amount of steel, but it has the advantages of easy manufacturing, equidistant electric field, easy availability of materials, and convenient installation and debugging Widely used in large and medium-sized gas purification plants.
