[0025] Furthermore, the T-shaped annular limiting portion 401 at the upper end of the rotating tube 4 is inserted into the T-shaped annular limiting groove 301 at the lower end of the outlet pipe 3 and is limitedly connected and rotated, so that the rotating tube 4 can rotate at the lower end of the outlet pipe 3. The rotation of the rotating tube 4 drives the arc blade 403 to rotate, causing the incoming exhaust gas to rotate.

[0026] Furthermore, the upper end of the rotating shaft 501 passes through the upper end surface of the air outlet pipe 3 and extends to the inside of the motor box 302 and is connected to the output shaft of the motor 303 through the coupling 304, and the rotating shaft 501 is driven to rotate by the motor 303.

[0027] Furthermore, the lower end of the rotating shaft 501 passes through the lower end of the fixed tube 5 and extends into the rotating tube 4 and is fixedly connected with the gear 502 .

[0028] Furthermore, the gear 502 on the rotating shaft 501 is meshedly connected with the teeth of the annular teeth 402 in the inner end surface of the rotating tube 4. When the motor 303 drives the rotating shaft 501 to rotate, the rotating shaft 501 drives the rotating tube 4 to rotate.

The foam cyclone bucket dust collector 1 and the dust cyclone bucket dust collector 2 have the same structure. The motor 303 drives the rotating shaft 501 to rotate. The gear 502 on the rotating shaft 501 is meshed and connected with the annular tooth portion 402 in the inner end face of the rotating tube 4. When the motor 303 drives the rotating shaft 501 to rotate, the rotating shaft 501 drives the rotating tube 4 to rotate. The rotating tube 4 rotates and drives the arc blades 403 to rotate, so that the incoming exhaust gas rotates (the dust removal mechanism is to make the dust-containing airflow rotate, and use centrifugal force to separate dust particles from the airflow and capture them on the wall, and then use gravity to make the dust particles fall into the ash hopper). The upper end of the air outlet pipe 3 of the dust collector 1 is connected to the second air inlet pipe 201 of the dust cyclone bucket dust collector 2 through the first air pipe 202. The foam cyclone bucket dust collector 1 settles most of the foam and transports the treated gas to the dust cyclone bucket dust collector 2 through the first air pipe 202. The upper end of the air outlet pipe 3 of the dust cyclone bucket dust collector 2 is connected to the side of the secondary dust collector 6 through the second air pipe 601. The dust cyclone bucket dust collector 2 settles most of the dust, and the remaining dust exhaust gas is transported to the secondary dust collector 6 through the second air pipe 601 for settlement. The exhaust gas treated by the secondary dust collector 6 is transported to the activated carbon filter 7, and the air after the exhaust hydrocarbon substances are filtered out by the activated carbon is discharged from the exhaust chimney.
