During purification, the flue gas enters the casing 1 through the air inlet 11, and the cathode needles 22 emit high-voltage electricity to ionize the flue gas molecules passing through the cylinder type electrostatic electric field 2 into positively charged particles, which are adsorbed on the inner wall of the anode cylinders 21, thereby achieving the effect of purifying the flue gas.

[0027] After a period of use, oil and grease will adhere to the inner wall of the anode cylinder 21, and the anode cylinder 21 needs to be cleaned regularly to ensure the flue gas purification effect. During cleaning, the rotating mechanism 3 drives the first rotating shaft 31 to rotate and drives the water spraying pipe 4 to rotate, the water inlet pipe 5 supplies cleaning liquid to the water spraying pipe 4, and the cleaning liquid is sprayed to the corresponding anode cylinder 21 through the plurality of spray heads 6, so as to achieve the purpose of automatically cleaning the inner wall of the anode cylinder 21 under the impact of the cleaning liquid. Since the plurality of spray heads 6 rotate around the axis of the first rotating shaft 31 during cleaning, the projection of the plurality of anode cylinders 21 on the vertical plane is located in the same circle, so that the cleaning liquid sprayed by the spray heads 6 can cover all the anode cylinders 21, achieving the purpose of cleaning the cylinder type electrostatic field 2 comprehensively, and the whole process does not need to disassemble the cylinder type electrostatic field 2, which is simple to operate.

[0028] In the above, the cleaning liquid can be tap water, water with a certain temperature, or water mixed with a cleaning agent, and the type of oil stain can be selected to select the cleaning liquid, and the cleaning liquid is not limited herein.
