Description

Road cleaning and purifying system

Technical Field

The invention relates to the technical field of environmental sanitation cleaning, in particular to a road cleaning and purifying system.

Background

When winter comes, except a few areas in China and south, ice and snow fall in winter, and the ice and snow are often accumulated on roads. The friction coefficient between the automobile tire and the road surface is reduced, the adhesive force is reduced, and the braking distance is prolonged particularly if a layer of thin ice is formed on the road surface. Causing many difficulties and dangers for the driving of the automobile. In modern times, to prevent the road surface from easily freezing, industrial salt is often thrown to the road surface after snow. The freezing point of water is zero, the freezing point of the added salt is reduced to about minus ten degrees, under the same temperature, the water can be frozen to cause the road surface to skid, the saline water can still keep the liquid form, and the danger of going out in snowy days can be reduced.

In addition, under the conditions of sufficient water vapor, breeze and stable atmosphere, when the relative humidity reaches 100%, the water vapor in the air is condensed into fine water drops which suspend in the air, so that the horizontal visibility of the ground is reduced, and the weather phenomenon is called fog and mostly appears between two to four months in spring. The presence of fog has a very negative impact on traffic safety. Conditions for forming mist: firstly, cooling and secondly humidifying, and increasing the water vapor content. Therefore, the fog can be eliminated naturally as long as the temperature and the humidity of the air can be changed.

Haze is also called dust haze, the haze weather is an atmosphere pollution state, and the haze is a general expression for various suspended particulate matters in the atmosphere exceeding the standard and is called as the haze weather. PM2.5 (particulate matter with an aerodynamic equivalent diameter of 2.5 microns or less) is considered to be "murder" in the hazy weather. Along with the deterioration of air quality, haze weather phenomenon appears increasing, and the harm aggravates. In many areas of China, haze weather phenomena are combined into fog to be used as early warning and forecast of disastrous weather. The production of haze mainly has industrial waste gas, automobile exhaust, family's burning biofuel etc. (all can produce corresponding haze like burning faggots etc.).

The following points are mainly related to traffic in the cause of haze weather:

firstly, the relative humidity of the air near the ground in the areas is relatively high, the dust on the ground is large, and the dust is stirred by people and vehicle flow on the ground; for example, if mud flows onto the road after the mud in flower gardens and teeth of streets in the middle green belts of the roads rains or is splashed with water, a large amount of dust can be generated by stirring the mud by wheels after the mud is dried for one hour, and even if the particulate substances fall back to the ground, the particulate substances are thrown to the upper space of the city again because the automobile continuously runs through the ground.

And secondly, no obvious cold air activity exists, the wind power is small, the atmosphere is stable, and the tiny particles in the air are gathered and float in the air due to the non-flowing of the air.

And thirdly, automobile exhaust is a main pollutant emission source, in recent years, more and more automobiles in cities are provided, and the emitted automobile exhaust is a factor of haze.

The road cleaning and purifying system in the embodiment further comprises a water pressure boosting device 7 arranged between the pipeline 1 and the municipal water supply network, and the pipeline 1 is connected to the municipal water supply network through the water pressure boosting device 7. The pipeline 1 is normally placed in a green isolation zone/island 99 in the middle of the road. The access point 8 of the municipal water supply network may be a hydrant-type water supply column, or of course, a water receiving port provided in a blind hole.

In this embodiment, the pipe 1 is one, and the front end of the pipe 1 is closed. In the present embodiment, the hydraulic pressure boosting device 7 is a booster pump, but may be any other device capable of increasing the hydraulic pressure in the pipeline 1. The water inlet end of the hydraulic pressure boosting device 7 is used for being connected to the municipal water supply network, and the water outlet end of the hydraulic pressure boosting device 7 is used for being connected to the rear end of the pipeline 1. The hot air generating device 2 is connected to the pipeline 1 through a check valve 4 at a position in front of the rear end of the pipeline 1.
