Measurement of Dust Control Efficiency of Wind Screens by Using 3-D Scanning Lidar

摘要

Wind erosion frequently occurs in the open storage yards of steel-making and power generation companies, which leads to a loss of raw materials and a cause of air-pollution, as well as environmental and health problems. In order to solve these issues, wind screens are a popular option to reduce wind-blown particle emissions in to the environment. However, only a few empirical and numerical simulations are available to assess their effectiveness in reducing particle emissions. In this study a scanning Lidar (Light Detection and Ranging) was used to validate the effectiveness of wind screens for abating wind erosion of dust in the open storage yards of the steel-making company. In addition, the information on the sources of wind-blown particle are quickly integrated by cloud computing techniques combined with the Lidar system and GIS (Geographic Information System) to strengthen the capabilities of the environmental monitoring and prevent the deterioration of air quality.
