S1, cooling waste gas: when the waste gas flows into the cooling pipeline (13) through the air inlet pipe (14), the spherical valve (12) on the cooling water pipe (11) is firstly regulated, the water pump (9) pumps the water of the water supply tank (8) into the cooling water pipe (11) through the water supply pipe (10), the cooling water pipe (11) sprays the water into the waste gas, the sprayed water flows into the spraying main pipe (26) at one end of the transverse position through the cooling pipeline (13), the air is blown into the air supply pipe (7) through the air pump (6), the air is guided to blow towards the direction of the filtering shell (5) by the air supply pipe (7), the cooled waste gas is upwards lifted through the pressure generated by the blowing of the air pump (6), and one end communicated with the top of the filtering shell (5) through the cooling pipeline (13) flows into the filtering shell (5);
S2, waste gas filtration: after the waste gas enters the filter shell (5), the motor (15) drives the rotating shaft (17) and the filter rotary drum (18) to rotate, suction force is generated when the filter rotary drum (18) rotates, the waste gas is filtered through the filter rotary drum (18), the waste gas which is not filtered can float downwards to be filtered for the second time through the filter screen plate (23), and the waste gas is discharged through the chimney (4) after the filtration is finished;
s3, cleaning a filtering mechanism: the cooling water pipe (11) spun rivers flow into spray in being responsible for (26), spray water in being responsible for (26) and spray on filtration rotary drum (18) and clean axle (28) through spraying branch pipe (27), when filtration rotary drum (18) pivoted, brush (29) on clean axle (28) clean the particulate matter on filtration rotary drum (18), after filtering, electric putter (25) drive spout (21) and filter screen plate (23) go up and down, soak filter screen plate (23) into in the ponding of filtration casing (5) inside downside, clear up the particulate matter on filter screen plate (23), discharge waste water through drainage component (3) after the clearance.
