Combination electrostatic precipitator is an industrial smoke and dust purification device. It is not only a coaxial combination of several tube type electrostatic precipitators, but also a series combination of single zone and double zone electrostatic precipitators. It also combines electric field and cyclone dust collection through electric rotation, and can be used as a unit for multiple parallel and series combinations. The upper end of the inner and outer pipes is separated by a ventilation duct, and the lower end is connected by an ash hopper. The flue gas enters the electric field of the inner tube tangentially through the air duct to form an electric cyclone dust collection, and then undergoes secondary dust collection in the ash hopper through sedimentation and electricity. The outer tube is a dual zone electric dust collection, and the dust is charged again in the ionization zone to complete the purification treatment of the flue gas in the uniform strong electric field of the dust collection zone; Discharged through the air duct.
