15 Critical thinking of Fog Cannon Truck

It is acknowledged that smog already has had a detrimental impact on China’s cities. A few years ago, there was a kind of special truck widely used in many cities to control smog called Fog Cannon Truck. The Fog Cannon Truck's spray system has a certain control effect on dust, reducing the content of large particles in the air, and has limited effect on tiny particles. The fog particles sprayed by the fog cannon are extremely small, reaching the micron level. In the fog and haze weather, the liquid fog can be used to reduce dust, decompose and dilute the concentration of particles in the air, and can effectively decompose the airborne particulate matter, dust, etc., and effectively alleviate the haze. According to reports, the purchase of the Fog Cannon Truck costs more than 800000 yuan， which is low cost performance. The particulate matter floating in the air is quickly forced down to the ground to achieve the effect of clean air purification.

Fog Cannon Truck needs water to produce fog, and the vehicles also emit carbon to the atmosphere. Although the electric Fog Cannon Truck and new technologies that can reduce the amount of water are used, the actual effect of fog cannons is not satisfactory. For small areas of dust and air treatment has a good effect. However, smog control for the entire city and region is like a cup of water to save a big fire.
