Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment equipment, in particular to an anti-blocking type flue gas purification equipment. Background Art

[0002] In industrial production, a large amount of flue gas is generated. Direct emission of flue gas will pollute the environment. Flue gas needs to be purified, and purification devices or equipment are needed for treatment. When treating flue gas, it is usually necessary to filter it first to prevent the large amount of smoke dust in the flue gas from affecting the subsequent spraying and purification process.

[0003] In a purification device for industrial flue gas emission treatment disclosed in the existing patent announcement number CN213221317U, the flue gas enters the filter bag through the ash hopper for dust filtration. The flower plate is arranged in conjunction with the electric telescopic rod, so that the flower plate can circulate in the box and make a large range of lifting and lowering movements, thereby driving the sliding ring brush on the anti-blocking cage to rise and fall. At the same time, due to the effect of inertia, the spring between the ring brushes strengthens the ups and downs effect, thereby realizing the back and forth brushing of the inner wall of the filter bag, cleaning the dust accumulated on the wall of the filter bag, and spraying water mist through the spray arm, so that the harmful gas can be fully cooled and purified in the spray box before being discharged outdoors.

[0004] When the above-mentioned purification device filters the flue gas through the filter bag, the electric telescopic rod can drive the flower plate to move up and down, so that the ring brush can brush the inner wall of the filter bag back and forth, which can reduce the blockage caused by dust accumulation. However, after cleaning, the dust is still placed in the filter bag, and it still needs to be cleaned for long-term use. In addition, the dust accumulates in the inner parts of the filter bag, affecting its use. In view of the above problems, an anti-blocking flue gas purification device is proposed.
