Dust suppression vehicle (also known as fog cannon vehicle or multifunctional dust suppression vehicle) is a special environmental sanitation vehicle that uses a high-pressure atomization system to convert water or dust suppressants into ultrafine water mist, combined with a fan for long-distance transportation to form a "water mist barrier", to achieve dust adsorption and settling. Its core positioning is the dual function of source suppression and aerial capture, which solves the problem of unorganized dust pollution in outdoor places. It is widely used in municipal sanitation, construction, industrial and mining enterprises and other scenarios, and is a key dust control equipment under the implementation of the Air Pollution Prevention and Control Law.
