Problems solved by technology

[0002] At present, in the dust removal equipment, most of the dust humidifying and stirring devices are equipped with a feeding cabin above the feeding cabin, and a mixing cabin is set on one side of the feeding cabin, and the collected dust is transferred from the feeding cabin to the feeding cabin. The feeding cabin is transported into the mixing cabin through the rotation of the helical blades of the helical mixing device. During the conveying process of the helical blades, a large amount of dust accumulation is easy to agglomerate or form mud after being wetted by the spraying device. In this way, the dust will accumulate or block in the cabin. , resulting in poor transmission
