the method comprises the following steps: when the cyclone dust collector is used, smoke enters the cyclone dust collector (2) from the air inlet pipe (22), the smoke enters a space between the outer cylinder (21) and the inner cylinder (23), the smoke directly impacts the cylinder wall of the inner cylinder (23), the smoke is limited by the shapes of the outer cylinder (21) and the inner cylinder (23), an external swirling flow from top to bottom is formed between the outer cylinder (21) and the inner cylinder (23), solid particles are thrown to the inner wall of the outer cylinder (21) due to most of inertia force in the rotating process and lose energy and slide down along the wall, the outer swirling smoke which rotates and descends is close to the center along with the contraction of a cone at the conical part of the lower part of the outer cylinder (21), an internal swirling flow from bottom to top is formed, and finally the smoke is discharged through the exhaust pipe;
step two: meanwhile, when smoke enters the outer barrel (21), airflow acts on the air plate (32), the air plate (32) drives the filter cover (24) to rotate, the filter cover (24) is subjected to downward acting force due to the fact that the air plate (32) is inclined, the limiting pin (25) on the filter cover (24) moves downwards, the limiting pin (25) drives the convex ring (28) to move, the convex ring (28) drives the supporting ring (27) to move, the supporting ring (27) drives the guide rod (30) to move downwards to enter the guide hole (29), the spring (31) is compressed, the filter cover (24) resets when smoke stops entering, the limiting pin (25) slides in the annular groove (26) to collide with the inner barrel (23) to enable the filter cover (24) to vibrate, the smoke passes through the filter cover (24) after rising, particles attach to the filter cover (24), the filter cover (24) rotates and the particles are separated from the filter cover (24) through vibration, so that the filter cover (24) is not easy to block, and the filtering efficiency is higher;
step three: the filter cover (24) moves to drive the support shaft (33) to move, the support shaft (33) moves to drive the reamer (34) to move, and the reamer (34) rotates in the outer cylinder (21) and moves up and down, so that dust in the outer cylinder (21) is removed more smoothly, and the dust is not easy to accumulate in the outer cylinder (21);
step four: the filtered smoke enters the pulse bag type dust collector (4) from the inner cylinder (23) through the connecting pipe, part of larger dust particles directly fall under the actions of inertial collision, natural sedimentation and the like, other dust particles rise along with airflow and pass through the filter bag (48), dust attached to the outer side of the filter bag (48) is continuously increased along with the continuous filtering process, so that the resistance of particles in the smoke passing through the filter bag (48) is gradually increased, when the resistance reaches a preset value, the pulse valve (47) is opened, compressed air enters the filter bag (48) through the pulse pipe (46), the filter bag (48) generates high-frequency vibration, and dust cakes attached to the outer side of the filter bag (48) are deformed and fall off;
step five: when the dust on the filter bags (48) is not thoroughly cleaned, the connecting shaft (49) is manually pulled, the connecting shaft (49) drives the connecting rod (56) to move, the connecting rod (56) moves to compress the pressure spring (51), the connecting rod (56) moves to press and deform the rubber plate (57), the connecting shaft (49) moves to drive the connecting seat (52) to move downwards, the connecting seat (52) drives the supporting plate (53) to move, the supporting plate (53) moves downwards to pull the filter bags (48), so that the filter bag (48) deforms, the connecting shaft (49) is loosened, the pressure spring (51) resets to enable the filter bag (48) to vibrate, further, dust on the filter bag (48) is shaken and loosened, meanwhile, the connecting shaft (49) is rotated to enable the connecting rod (56) to rotate, the connecting rod (56) drives the rubber plate (57) to scrape and rub the inner wall of the box body (41), and the dust in the box body (41) is cleaner during removal;
step six: the purified flue gas enters the UV photolysis and activated carbon adsorption integrated equipment (6) from the gas outlet (45) through the connecting pipe for treatment, and after the treatment is finished, the flue gas enters the alkaline washing spray tower (7) through the connecting pipe for alkaline washing, and is finally discharged to the atmosphere.
