Description

A large cleaning vehicle with pure vacuum function

Technical field

The utility model belongs to the technical field of environmentally friendly vehicles, and specifically relates to a large-scale cleaning vehicle with pure dust collection function.

Background technique

Respirable particulate matter comes from direct human emissions, mainly from the combustion process, such as the burning of fossil fuels (coal, gasoline), the burning of biomass (straw, firewood), and secondly from gases that are converted into respirable particulate matter in the air. Pollutants mainly include SO2, NO2, NH3, and TVOC. Other sources such as road dust, kitchen smoke, forest fires, pollen, fungal spores, etc. can also lead to increased levels of respirable particulate matter in the air. After inhaling respirable particulate matter, it will accumulate in the respiratory system and cause many diseases. The smaller the diameter of the particles, the deeper they enter the respiratory tract. Particles with a diameter of 10um are usually deposited in the upper respiratory tract. Particles with a diameter of 10um or more will be blocked from the human nose; particles with a diameter between 2.5 and 10um can enter the upper respiratory tract, but some can be excreted through sputum, etc. Outside the body, the harm to human health is relatively small.

Large-scale cleaning vehicle equipment currently on the market generally has sweeping and suction functions. After sweeping the ground garbage, it is sucked into the equipment compartment. Some equipment is equipped with a spray mechanism during cleaning to avoid dust generation during the cleaning process. After nights when there are fewer vehicles on the road, dust in the air accumulates on the road in the early morning. As the number of vehicles on the road increases, the accumulated fine particles are picked up by the passing vehicles and re-dispersed in the air, reducing the daytime air quality. The current common dust removal method is spray dust suppression, which captures fine particles and causes them to settle. After settling, the fine particles fall in the shape of mud dots on the nearby ground; as the water evaporates, the rolling friction of the tires of passing vehicles , fine particles re-disperse in the air. Therefore, this method cannot effectively take advantage of the opportunity when dust accumulates on the road at night to effectively remove fine particles near the ground, thereby effectively purifying the air.
