A few days ago, when passing by the Fuxi Raod, Wujin District, the journalist discovered a strange "cannon vehicle"
There was a large-diameter steel pipe hanging in the rear of the vehicle, and it sprayed water mist at the length of tens of meters (as shown in the picture). In fact, this is the first batch of "artifact" for haze control purchased by our municipal environmental protection department – multi-functional dust-suppression vehicle, commonly known as "mist cannon vehicle", total 4.
At present, one is conducting dust-suppression and haze-reduction work in central city of Wujin, and the other three vehicles have not been put into use yet. Zhou Yanqin, station-master of Wujin District Environmental Monitoring Station told the journalist that, operating principle of the "mist cannon vehicle is to form water mist after spraying the water making use of the fan when starting the liquid pump. The water mist particles may conduct effective absorption of dust particles hanging in the air, thus playing the role of lowering the density of PM 10 and PM 2.5. According to relevant monitoring data, PM 10 in the air may be lowered by 10% - 20%, and PM 2.5 may be lowered by 3% - 5%. It was introduced by Zhou Yanqin that, the "mist cannon vehicle" starts to work when the air pollution reaches the middle level, and conducts constant spraying in central urban area of Wujin. She also disclosed that, such vehicle is still of great potential in dust-removal in construction sites and other fields.
