摘要：In order to effectively control the dust pollution caused by the receiving pit in the receiving process, this paper takes the receiving pit of the Harwusu open-pit coal preparation plant as the research object, and through the field test, observation analysis and three-dimensional numerical simulation, the dust pollution of the receiving pit is obtained, law. According to the law of dust pollution, a dust removal scheme for setting the fogger at the edge of the receiving pit is proposed. The computational fluid dynamics simulation software was used to simulate the dust pollution changes at different times during the truck unloading process, and the optimal working parameters of the aerosolizer were determined. Through the three-dimensional numerical simulation of the dust concentration distribution of the receiving pit and the field application test of the Harwusu open-pit coal mine, the dust-reducing effect of the fogger on the dust pollution of the receiving pit is analyzed and verified. The results show that when the remote fogger is installed in the pit, the dust reduction efficiency is up to 93% when the inlet wind speed is 30 m/s. The dust removal scheme provides theoretical and practical basis for the dust control of the pit of the coal handling system.
