Refined Dust Fine Control Method of Bulk Cargo Yard Based on Whole-field Monitoring

Abstract

The fine dust control method and control system of bulk cargo yard based on whole-site monitoring are realized through the following paths. Firstly, the extinction coefficient of the whole area of the storage yard is obtained by using lidar, and the proportion relationship between the extinction coefficient and the dust concentration data measured at the same position is obtained to obtain the dust concentration distribution in the whole area. Secondly, the radar scanning plane is divided into N grids with the control range of each spray head as a grid unit, and the average dust concentration in each grid is calculated. Thirdly, the critical value of the average dust concentration and the critical value of dust contribution rate are set to judge the grid that needs to start the sprinkler head. Repeat the above process to achieve continuous fine control of dust in bulk cargo yard. The system not only improves the efficiency of dust suppression, but also reduces the amount of sprayed water, achieves the purpose of improving the efficiency of environmental protection effects, reducing the labor intensity of workers, and maximizing the utilization of water resources while effectively removing dust.
