Abstract

The invention discloses a simulation system and method for suppressing road dust and reducing PM2.5 (particulate matter 2.5). The system comprises a road dust simulation system, a road sprinkling system and a road dust collecting and monitoring system, wherein the road dust simulation system is used for reproducing dust generated by factors such as negative pressure of automobile tires, the road sprinkling system is used for reproducing a sprinkling truck on an urban road or rainwater in snow and rain, and the road dust collecting and monitoring system is used for collecting the dust, observing change of the dust along with time after sprinkling and providing numerical values for subsequent research. The dust is reduced by simulating real road sprinkling, data are recorded by relevant instruments such as a PM2.5 tester, the test data are analyzed by the aid of the statistical theory, so that a reasonable method for reducing the PM2.5 is determined, the PM2.5 in environments can be reduced, and the system is easy to operate.

Description

technical field [0001] The invention relates to a simulation system and method for reducing PM2.5 (fine particulate matter), in particular to a simulation system and method for reducing PM2.5 by sprinkling water to suppress road dust. Background technique [0002] In recent years, my country's rapid urbanization and motorization have resulted in the concentrated release of a large amount of pollutants into the atmosphere. Coal combustion, motor vehicle exhaust and dust emissions cause multiple pollutants such as SO2, nitrogen oxides (NOx), mineral aerosols and organic matter to exist at the same time, and undergo complex interactions to transform into more harmful pollutants mainly in Secondary pollutants in fine particles have caused extremely serious and complex air pollution in my country. [0003] my country's air pollution prevention and control work for decades has mainly focused on the smoke and dust removal of industrial pollution sources. Significant progress has be...
