Road spray system

Road spray spraying equipment

sketch

The road light pole spray spray system takes advantage of the characteristics of wide distribution, high density and fixed location of the road light poles, makes full use of the monitoring data of "Internet of Things" and "microstation", and carries out road dust reduction in a planned way, which can solve the problem of small operation area and large spray drops of fog artillery.

Working principle

The street light sprinkler system is a system that utilizes existing street light poles to install sprinkler devices. Based on the principle of atmospheric water mist cleaning, high-altitude sprinkler points are set up in the dust control area to form a micron level water particle curtain in local areas, effectively reducing suspended particles in the floating air.

Opening conditions

The layout design of street light sprinkler is based on the location of the water intake point, and the number of nozzles is set comprehensively according to the road traffic volume and street light shape. By controlling the power supply facilities through the Internet of Things, the spray facilities can be turned on when the air humidity is below 60% and above 70%, and when the wind speed is high, to accelerate the pressure drop of particulate matter concentration. When the air humidity is between 60% and 70% or the wind speed is low, the spray facilities can be turned off to avoid adverse effects.

In addition to retaining the current opening and closing mode, the R&D indicator control link sets upper and lower limits for PM values, automatically opens and closes purification facilities based on government monitoring data of PM2.5 and PM10 from "micro stations", adjusts street light spraying strategies in real time, forms a 24-hour cycle dust reduction, and gradually realizes the transformation from traditional manual dust reduction mode represented by mobile fog cannons to intelligent dust reduction. Combining physical spraying with chemical agents to effectively reduce the levels of PM2.5, PM10, and ozone in the air, thus reducing air pollution.
