s1: introducing gas mixed with particles and liquid into the inner barrel (1) along the tangential direction of the inner barrel (1) and forming rotary airflow;
s2: separating the liquid in the rotary airflow in the step S1 into an outer barrel (5) arranged outside the inner barrel (1) through a filter screen (4);
s3: separating the particles of the rotary airflow in the step S2 to an inner barrel (1) or a filter screen (4) through rotation, and discharging the gas in the rotary airflow through an air outlet arranged on the inner barrel (1);
s4: blowing the particles on the filter screen (4) in the step S3 to the inner barrel (1) by using a blowing device;
s5: when solids are accumulated above a discharge hole of a first discharge pipe (32) at the bottom of the inner barrel (1), a first material turning plate (33) is pushed to discharge the materials, and then the materials are quickly closed again, so that the air pressure balance in the whole cyclone separation device is not damaged;
s6: after liquid is accumulated above a discharge hole of a second discharge pipe (34) at the bottom of the outer barrel (5), the second material turning plate (35) is pushed to discharge the material and then quickly returns to be closed, so that the air pressure balance in the whole cyclone separation device is not damaged.
