Description

A large cleaning vehicle with pure vacuum function

technical field

The invention belongs to the technical field of environment-friendly vehicles, and in particular relates to a large-scale cleaning vehicle with a pure dust collection function.

Background technique

Respirable particulate matter comes from direct human emissions, mainly from combustion processes, such as the combustion of fossil fuels (coal, gasoline), biomass (straw, firewood), and secondly from gases that are converted into respirable particulate matter in the air Pollutants mainly include SO2, NO2, NH3, TVOC. Other sources such as road dust, kitchen fumes, forest fires, pollen, fungal spores, etc. can also contribute to increased levels of respirable particulate matter in the air. After inhalation of respirable particulate matter, it will accumulate in the respiratory system and cause many diseases. The smaller the diameter of the particle, the deeper it enters the respiratory tract. Particles with a diameter of 10um are usually deposited in the upper respiratory tract, and particles with a diameter of more than 10um will be blocked out of 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. In vitro, the harm to human health is relatively small.

At present, the large-scale cleaning vehicle equipment on the market generally has sweeping and suction functions. After cleaning the ground garbage, it is sucked into the equipment compartment, and some equipment is equipped with a spray mechanism during cleaning to avoid dust during the cleaning process. After the night when there are fewer vehicles on the road, the dust in the air accumulates on the road in the morning. With the increase of vehicles on the road, the accumulated fine particles are picked up by the passing vehicles and re-floated in the air, reducing the daytime air quality. At present, the general dust removal method is to carry out spray dust suppression, and settle the fine particles by capturing the fine particles. The settled fine particles fall on the nearby ground in the form of mud dots; , fine particles re-dispersed in the air. Therefore, this method cannot effectively take advantage of the timing of dust accumulation on the road after night, and efficiently remove fine particles near the ground, thereby effectively purifying the air.
