Abstract：In order to solve the problem of high dust concentration in transport corridor of coal preparation plant,the article takes the transport corridor of Xinjiang Qitai coal preparation plant as the research object,and based on the gas-solid two-phase flow theory and DPM model,uses the Fluent software to conduct a numerical simulation study on the dust distribution law of the transport corridor,and designs a set of automatic spray dust removal device.The results show that the distribution of air flow field near the conveyor belt surface can be changed by controlling the running speed of the belt.The conveyor best transport speed of the belt is 2 m/s.The dust removal cover installed at the tail of the transport corridor can effectively reduce the dust pollution in the gallery.The optimal exhaust air volume of the fan of the dust removal system is 9 500 m3/h.The dust concentration sensor and spray nozzle added on site can effectively realize the function of dust concentration monitoring and automatic spray dust removal,which provides an effective way for the transport corridor dust prevention and control of coal preparation plant.
