[0022] The working principle and advantages of this utility model are as follows: By fixing the top of the dust collector bag to the bag flange 3, hot flue gas enters the tank 1 through the smoke inlet pipe 2. The first drive mechanism is activated to drive the sealing plate 8 to rotate, so that the through hole 9 on the sealing plate 8 coincides with the fixed hole 7 that needs to be purged. The hot flue gas is transported to the moving pipe 4 and purged through the purging hole 5 to purge the dust collector bag. The adjustment mechanism is activated to drive the sealing plate 8 to move up and down reciprocally. At the same time, the second drive mechanism is activated.
