There was no cloud in the sky. There was a hot sun above the head. There was no wind. All the trees stood lazily and lazily in the summer. Some time ago, a "water gun" appeared, and these big guys were also seen closing the past few days. Like "Bai Bai," they were white. The sky is slowly falling and the hot air becomes fresh. Some citizens feel new and stop to take photos with their mobile phones. To find out what this monster is, I did a survey:

I found on the scene that this guy is a Taiwan spray duster . Compared with large trucks, the difference is that there are not only water cannons on the back, but also power generation systems and water storage systems. “The water spray range of this multi-functional dust-reducing vehicle can reach 100 meters backwards and 60 meters upwards. Considering that there are pedestrians and pedestrians on the road during the day, there are other vehicles behind and the water cannons are specially designed for spraying water mist. The range is controlled under 30 meters. In this way, the momentum is astonishing.” At full load, a water cannon can suppress the dust above and behind two or three lanes. The power of water cannons is even The dead leaves on the tree can be dropped onto the ground to facilitate the cleaning of the equipment. "Water cannons have cooling effect in summer. Standing on the side of the road, the temperature of body temperature is obvious. After falling dust in winter, the air can be felt in the line of sight. The dust in the air is entrained and dropped to the ground." To control and reduce Road dust pollution, from 4 am to 7 am, will arrange the sprinkler to wash the ground with high-pressure water to carry out general sweeping. “Previously, it was to sweep the ground. Now it is a land scrub, and within a week, it can finish the flushing of all the sidewalks in the area.” Every morning and evening at 7 o'clock in the morning and once in the morning, each circle takes 30 minutes. Before the sprayer sprayed the water, it also passed the on-board 3-stage filtration. As the water is clean and the water mist is heavy, some private car drivers have also specifically washed the car with the sprayer. It was learned from the sprayer that the mist particles of the spray duster were extremely small compared to the water spray from ordinary sprinklers. Due to strong adsorption and low water consumption, dust in the air can be effectively reduced. Dust-reduction tests performed well.

The spray truck not only escorted us in the hot summer but also applied to more and more fields. The main purposes of the sprayer are sanitation, watering, landscaping, cooling and dust removal, temporary firefighting, drought transport, and pesticide spraying. Pollution on the construction site and in the mining area has received increasing attention. Everyone knows that the source of pollution is dust and dust. In recent years, the state has issued new regulations for dust reduction in construction areas. The hard index mining and mining area that sprays dust at least three times a day must be completed. The use of traditional water pipe spraying method is time-consuming and labor-intensive, and the effect is not good. Therefore, at present, dust reduction at the construction site has become more and more widely used as a substitute for sprinkler trucks. (Text / Kang Shaowu)
