[0037] It should be noted that when dust exists in the flue gas or gas generated by industry, the air needs to be treated before being discharged into the atmosphere. The gas is introduced into the inside of the electrostatic precipitator main body 1 through the pipeline, a high-voltage electric field is arranged in the electrostatic precipitator, the particulate matters in the gas are charged, the charged particulate matters in the electric field are separated out under the action of the electric charge, and fly to the polar plate 3 in a directional manner. After the particulate matters fly to the polar plate 3, they adhere to the polar plate 3. The dust adsorbed by the polar plate 3 will accumulate on the polar plate 3. The electrostatic precipitator has low energy consumption and high dust removal efficiency, and can be used in occasions with high flue gas temperature and large pressure. The larger the amount of flue gas to be treated, the more economical the investment and operation cost of the electrostatic precipitator. When the dust on the polar plate 3 needs to be cleaned, the air blower 7 works so that the airflow of the air blower 7 enters the inside of the fixed pipe 43.

The airflow can be used to clean the dust on each polar plate 3. The dust on the surface of the polar plate 3 is cleaned more conveniently and quickly, and the electrostatic precipitator does not need to be disassembled.

[0038] Please refer to Figure 2 , Figure 4 and Figure 5As shown, the outer side of the intermediate tube 45 and the fixed tube 43 is provided with a wind direction adjusting structure 5, which includes a synchronous wheel 51 welded on the cylindrical surface of each intermediate tube 45, each synchronous wheel 51 is arranged on the same side of the fixed tube 43, and a synchronous belt 52 is arranged between adjacent synchronous wheels 51, the synchronous wheels 51 of each intermediate tube 45 are driven by the synchronous belt 52, the rotating direction of each intermediate tube 45 is the same, the blowing port 46 of the fixed tube 43 rotates synchronously with the fixed tube 43, and the wind blown by the blowing port 46 is used to clean the dust on different positions of the plate 3. When the intermediate tube 45 rotates inside the fixed hole 44, one of the intermediate tubes 45 can drive the other intermediate tubes 45 to rotate. Specifically, the synchronous belt 52 is used to rotate the synchronous wheels 51 of two adjacent intermediate tubes 45, the synchronous wheels 51 arranged between each intermediate tube 45 rotate synchronously, and the blowing port 46 of each intermediate tube 45 also rotates synchronously, so that the blowing port 46 blows the surface of the plate 3.

[0043] It needs to be explained that the air flow generated by the air blower 7 enters the inside of the fixed tube 43, because the two interval plates 53 in the interval plate 53 are in the horizontal state at the beginning, the cross section of the fixed tube 43 can be sealed, avoiding the air flow flowing to the middle tube 45, when the air blower 7 continues to flow, the air pressure at the upper end of the fixed tube 43 becomes larger, at this time, the rotating plate 55 can be deflected, the rotating plate 55 rotates around the first rotating shaft 56, under the action of the telescopic spring 59, the interval plate 53 can be driven to deflect, the air flow can be discharged from the gap of the interval plate 53, the air flow enters the inside of the middle tube 45 from the air permeable groove 48, the air flow is normally blown out from the inside of the middle tube 45, so as to clean the surface of the pole plate 3, and the synchronous belt 52 between the adjacent two middle tubes 45 drives the synchronous wheel 51, so as to ensure that the middle tube 45 rotates synchronously, the air outlet 46 can blow the wind to different positions, so as to clean the dust at different positions of the pole plate 3.
