Technical Field

[0001] The utility model relates to the technical field of vehicle dust removal, in particular to an on-vehicle terminal foaming / cavitation spraying device for dust removal. Background Art

[0002] Spray dust suppression is a new type of dust suppression technology, which pressurizes and atomizes the supplied water and sprays it into the dusty air to inhibit and capture dust, so as to achieve the purpose of purifying the air environment, and has a good effect on dust control in large open areas. A large amount of dust will be generated during open-pit mining and transportation. High-concentration dust may cause respiratory diseases such as pneumoconiosis, and will also reduce the working conditions and easily cause production safety accidents.

[0003] Among them, the generation of dust during the transportation of minerals by heavy-duty trucks is one of the important ways of dust generation. Currently, most of the dust control on the road surface uses sprinkler dust suppression, and fog guns are used for dust suppression in a few road conditions. However, both manual sprinkling or using a sprinkler truck for dust removal occupy the lane, which not only cannot effectively inhibit the generation of dust, but also affects vehicle traffic to a certain extent and is not conducive to the efficient transportation of heavy-duty trucks.
