In response to continuing mist and haze weather in recent days, and in order to reduce dusts in construction sites and roads quickly, our municipality started to use the "dust-removing artifact" – mist cannon vehicle. On the 10th, the first mist cannon vehicle in our municipality conducted dust-removal operation in Shengfeng Road, Xiangcheng District.

The picture is the first demonstration training of the multi-functional dust-suppression vehicle newly introduced by Xiangcheng District Government, in demolition area of Shengfeng Road.

It is known that, the vehicle adopts air-assisted sprayer of environmental protection and dust suppression, and is commonly known as "mist cannon vehicle" since it looks like cannon bore in appearance. "Cannon bore" is rotatable for 180 degrees, the inner part is a fan with the maximum wind at level 7, the outer part has two layers of circular spraying circles, and there are 98 small mist cannon muzzles in total. After misting, the water column sprayed from the mist cannon muzzles is blown out by strong fan and can reach 120 meters for the farthest, and can conduct absorption and aggregation of the dust particles in the air, make the dust fall under gravity action, and effectively lower density of PM 10 and PM 2.5 in the air. Water tank in the middle of the mist cannon vehicle is available for 16.5 tons of water, and is able to work for 1.5 to 2 consecutive hours under normal condition.

It is expressed by work staff of municipal atmosphere office that, the mist cannon vehicle may simulate the status of wind and rain in the operating area, so as to effectively lower the density of fine particles in the air. Hereinafter, it will be mainly used in construction sites, demolition areas, roads, goods yard and other places of severe dusts, so as to remove dust and suppress haze effectively.
