Description

Technical Field

[0001] The utility model relates to a water mist dust collector, belonging to the field of dust removal equipment. Background Art

[0002] There is a large amount of dust at the coal mine production site. In order to achieve the effect of dust reduction, arc-shaped spray pipes are often laid in the coal mine tunnels. A plurality of atomizing nozzles are evenly installed on the outer surface of the spray pipes, so that the spray pipes are connected to the compressed air pipeline and the water supply pipeline. After opening the valves on the compressed air pipeline and the valves on the water supply pipeline, compressed air and water flow into the spray pipe together. Under the action of the compressed air, the water forms water mist and is discharged from the atomizing nozzle. The spray pipe is installed with protruding water inlet joints and air inlet joints. During storage or transportation, the protruding air inlet joints and water inlet joints are easily squeezed and damaged. Therefore, it is necessary to design a water mist dust collector that prevents the air inlet joints and water inlet joints from being squeezed and damaged. Utility Model Content
