s4, when the dusty airflow moves upwards and meets water drops, the dusty airflow bypasses an object to flow, the motion track is changed from a straight line to a curved line, wherein fine dust particles bypass the airflow together, the dust particles with large (0.3 PM) and heavy weight are separated from the airflow due to large inertia and keep moving linearly so as to collide with the water drops, the dust particles with the particle size of less than or equal to 0.3PM move like gas molecules, are captured due to diffusion and water drop contact in the motion process, when the radius of the dust particles is greater than the distance from the dust center to the edge of the water drops, the dust is adhered by the water drops and captured, then fall into a lower dust hopper (19) along with the water drops, finally fall into a dust collection box (14), and the clean gas passes through a demister (17) and is discharged from an air outlet cylinder (7);
s5, when the motor (15) works, the stirring paddle (21) is driven by the stirring rod (20) to rotate slowly, sewage in the dust collection box (14) can be stirred, meanwhile, the sewage can be discharged from the discharge pipe (26), the discharged sewage can be filtered, lime dust in the sewage is filtered, and the lime dust can be recycled;
s6, after dust collection is completed, conveying of dust gas can be stopped, then the electromagnetic valve (24) is opened, water in the spraying main pipe (16) enters the spraying branch pipe (23), and finally is sprayed out from the high-pressure nozzle (25), the sprayed high-pressure water flow can be directly sprayed on the surface of the inner wall of the dust collection cylinder (1), and dust and lime dust adhered to the inner wall of the dust collection cylinder (1) can be washed down and then flow into the dust collection box (14).
