6. The self-cleaning air distributor for the inner wall of a pipeline according to claim 5, wherein: the rectifier is arranged in the air inlet to respectively guide the fresh air entering from the air inlet to the direction of the air supply openings at the two ends, so that the fresh air is prevented from being directly blown to the inner wall opposite to the air inlet.
7. The self-cleaning air distributor for an inner wall of a pipeline according to claim 6, wherein: the rectifier comprises at least two minor arc plates, one end of each minor arc plate faces the air inlet, the other end faces the air supply opening, and the other end of at least one minor arc plate faces the opposite direction to the other ends of other minor arc plates so as to ensure bidirectional flow guiding.
8. A self-cleaning method for the inner wall of a pipeline is characterized in that: the method is carried out based on the self-cleaning wind separator for the inner wall of the pipeline according to claim 2; the method comprises the following steps:
1) Closing the air supply outlet;
2) Rotating the cleaning deflector into the ventilation duct and maintaining the open state so as to reduce the airflow area at the position;
firstly, the cleaning guide plate is opened, and then the main rod is manually rotated to overcome the spring force, so that the main rod is rotated along the rotating shaft rod to be opened and supported at the position of the bearing groove, and the opening state of the cleaning guide plate is maintained;
3) Fresh air is continuously fed from the air inlet, the fresh air flow passing through the free end of the cleaning guide plate is extruded and accelerated and then led to the subsequent ventilating duct, and the accelerated fresh air flow is flushed and cleaned on the inner wall of the subsequent ventilating duct section and then is discharged from the cleaning air outlet so as to realize automatic cleaning on the inner wall of the duct.
