Problems solved by technology

However, frequent mechanical vacuum cleaning and water spraying will also affect traffic, and can only be carried out during specific periods of time, which cannot guarantee the control and reduction of fine particles during the full period of vehicle driving; and road sections, when vehicles pass by or encounter disturbances such as windy weather, there will still be a large amount of fine particles diffusing into the air, seriously affecting urban air quality and endangering human health

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described by embodiment:

[0022] A method for controlling urban road fine particle pollution, comprising:

[0023] a. Install vehicle sprinklers on buses and taxis in the city.

[0024] The vehicle sprinkling device is composed of a water tank 2, a pipeline 3, a tail drip pipe 4, a control valve 5, a control circuit 6 and a control switch 7. The capacity of the water tank is 50L ~ 350L. The water tank 2 is connected with the control valve 5 through the pipeline 3, the control valve 5 is connected with the control switch 7 through the control line 6, and the control valve 5 is connected with the tail drip pipe 4 through the pipeline 3. The water tank 2 and the tail drip pipe 4 are respectively installed in the trunk of the bus and the taxi vehicle 1 and at the bottom of the car; the control switch 7 is arranged on the control panel of the driver's cab, and is manually operated by the...

Abstract

The invention discloses a method for controlling the pollution of fine particles on urban roads. According to the perfect method, urban buses and taxies are used as carriers, and watering devices are installed on the buses and the taxies which are used as urban dust cleaning vehicles and watering washing vehicles by utilizing the running of the vehicles on urban streets. By implementing the method, the ground moisture is kept, the absorption and adsorption capability on the fine particles in near-surface air is increased, road dust is reduced, the pollution of the fine particles on the urban roads to air is controlled, and the ambient air quality of the urban traffic roads are improved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a method for controlling urban road fine particle pollution. Background technique [0002] Road fine particles refer to soil or other substances that are finely dried and powdered, including dust accumulated on roads and streets, under certain dynamic conditions (wind force, motor vehicle rolling or crowd activities) They are mixed together and enter the ambient air to form particles with a certain size distribution. Air particulate matter pollution is serious in cities in my country, and fine particulate matter on urban roads has become one of the important factors that endanger the quality of urban ambient air. my country's environmental quality bulletin pointed out that in 2011, among 325 cities at the prefecture level and above (including some prefectures, states, league locations and provincial cities), the proportion of cities with ambient air quality excee...
