The Rear Double Axle 20-ton Dust Suppression Vehicle, also known as a fog cannon truck or multifunctional dust suppression vehicle, is a high-tech product born from the smoggy weather and is known as the “miracle weapon against smog.” The multifunctional dust suppression vehicle is equipped with a large fog cannon that can spray water mist up to 120 meters away and 70 meters high. The water mist particles are extremely fine and can be used for liquid mist dust suppression in smoggy weather. The multifunctional dust suppression vehicle combines watering and spraying functions; it can use the spray cannon to spray fine mist into the air at high altitudes and long ranges, bringing pollutants to the ground to restore air quality. It can also be used for road washing, greenery spraying, watering, pesticide application, emergency firefighting, and water pumping and drainage. There have been reports of fog cannon trucks being used in Changsha to combat smog.

The Rear Double Axle 20-ton Dust Suppression Vehicle comes standard with front washing and rear sprinkling, side spraying, and a rear-mounted working platform. On the platform, there is a high-pressure water cannon (360° rotatable, can be adjusted to a columnar spray range of 35 meters or a mist spray range of 15 meters, with settings for direct jet, heavy rain, medium rain, light rain, and drizzle). It is equipped with a high-power specialized watering pump, power take-off, debris filter screen, national standard 65-type fire interface (can be filled with water from a fire hydrant), and 1 set of gravity ball valve system (can self-suck and discharge, can pump water from rivers or ponds into the tank, with a suction range of 7 meters), and 2 rubber hoses with steel wire. The pump, power take-off, ball valve, and filter screen are all national standard products. The main pipeline is thickened, the flange gasket and flange plate are reinforced, the universal ball valve is large in diameter, and it features excellent performance, reliability, high efficiency, large flow rate, and convenient maintenance.

The tank structure of the Rear Double Axle 20-ton Dust Suppression Vehicle is oval or square-round, made of Wugang carbon steel, formed in one step using a large roll forming machine, and welded automatically with advanced equipment, making it more aesthetically pleasing and better sealed. The vehicle’s tank is divided into 2-3 compartments, with a through-hole at the lower end of the intermediate partition. The tank is equipped with anti-sloshing and anti-swell partitions that reduce the impact of the liquid inside the tank while the vehicle is moving. The exterior is coated with anti-rust paint and decorative paint.

The tail of the tank of the Rear Double Axle 20-ton Dust Suppression Vehicle features a large platform that can carry a 30-meter vehicle-mounted wind-assisted spray unit. It has the characteristics of strong power, long range, strong penetration, strong adhesion of mist particles, wide coverage, and precise spraying, making it suitable for dust suppression in windy and sandy conditions, as well as at construction sites and demolition sites. It is specifically used for dust and sand control in urban development areas, construction sites, demolition sites, railway stations, coal storage yards, coal washing plants, coking plants, iron ore mines, steel mills, ports, etc. In the event of smoggy weather or when the air quality PM2.5 seriously exceeds the standard in the city, it can randomly select an area for liquid mist dust suppression, decompose and dilute the particle concentration in the air, and quickly force the floating pollution particles and dust in the air to the ground, achieving a significant and good effect of air purification and treatment.
