Recently, frequent watering has played a positive role in the air quality in Lanzhou, but it cannot be sprinkled when the temperature drops below zero. To this end, Lanzhou invested more than 20 million yuan to purchase 40 new environmentally-friendly sanitation vehicles, which will become the new force for dust and haze in the future. On October 27, the first 18 vacuum cleaners and spray trucks appeared on the streets yesterday, demonstrating their strong fighting power. Near the north gate of Xingang Road in the south of Binhe Road, three new road cleaning vehicles are operating. Among them, a vacuum cleaner called “Urban Vacuum Cleaner†is very attractive. On the chassis of the white vehicle, it contains a large suction cup and rotating brush, which not only can vacuum, but also can suck away the road area with strong suction. Water, snow. During the entire operation, no dust was seen. After the vehicle was seen passing through, sand, dead leaves, plastic bottles, and other miscellaneous materials were all light-absorbed, and the road surface became immediately clean. There is also a secret weapon on the vacuum cleaner, which is mainly used to clean the sidewalks and green tree litter. The sanitation worker pulled a large suction cup from under the vehicle. A thick, long hose connected the suction cup to the vehicle. The sanitation worker was holding the suction cup at the sidewalk and tree nest. The garbage on the road surface and the tree nest was powerful. The suction sucked away. At the same time, there is a sprayer similar to a large-scale humidifier. The water sprayed by the device is mist like a humidifier. It can also be sprayed in multiple angles, effectively reducing PM2.5, and it can be used in winter. There is water accumulation in the road. I saw this sprayer like a transformer. The stand with a nozzle slowly lifted up to a height of ten meters. Then the curtain of mist sprayed down. The air that the vehicle passed was air. Can feel the warm atmosphere, but can not see the watermark on the road, this way, the winter is not afraid of freezing. In this vehicle, there is also a secret weapon with strong fighting power. Under the operation of the staff, only a water column is seen flying over a distance of more than ten meters. Gradually, the water column is getting shorter and shorter, but the water spray area is Gradually increase. It turns out that as long as the pressure at the outlet is adjusted, the water column can be adjusted. The operator said: "This device can effectively reduce the secondary dust on the demolition site, and it can also clean green trees." Ning Bureau of Law Enforcement Bureau of Lanzhou City, told reporters that the clean-up rate of these new types of sanitation vehicles can reach 98%, and has a significant effect on dust and hail. "When the temperature drops below zero, we stop spraying water. These sanitation vehicles are all on duty. They are responsible for the sanitation work of the main and secondary roads in the four suburbs of the suburbs."
