The dust is sucked into the vertical shell through the air supply pipe, driving the water pump to work. The water pump drives the water in the second cavity to enter the vertical shell through the water supply pipe, spraying water, spraying dust, and the water absorbs the dust. Further, it falls into the first cavity. When the water accumulates to a certain height in the first cavity, the water overflows from the first cavity to the second cavity. This structure prevents the dust from being released into the environment again. In addition, this structure can recycle water for dust removal. When the water accumulates to a certain height in the first cavity, it can effectively precipitate sand and gravel in the water. BRIEF DESCRIPTION OF THE DRAWINGS
