摘　　要：通过分析国内煤矿常用的乏风引风装置的优缺点,设计了一种安装于煤矿扩散塔之上的引风装置,采用COMSOL Multiphysics多物理场仿真模拟软件,建立了模型,通过数值模拟对引风装置上部开口尺寸进行优选,确定了乏风引风装置相关尺寸参数。基于数值模拟结果潞安集团高河煤矿设计安装了乏风引风装置,引风装置安装后,RTO乏风氧化装置运行时,乏风氧化装置吸风侧瓦斯浓度为0.30%,吸风量8 400 m^3/min,矿井阻力降低10~30 Pa;RTO乏风氧化装置停运时,实测矿井阻力增加45~50 Pa,与数值模拟结果较为吻合,从而验证了数值模拟结果的正确性。The advantages and disadvantages of the commonly used wind guide device in coal mine ventilation air methane oxidation system are analyzed. A type of wind guide device is designed, the model is established by the software of COMSOL Multiphysics, through numerical simulation, the upper opening size of the wind guide device is optimized. Based on the numerical simulation results, the wind guide device has been designed, made and erected by Gaohe coal mine of Lu＇an Group. When the RTO system is running, the gas concentration is 0.30%, the air volume to RTO is 8 400 m^3/min, and the mine ventilation resistance is reduced by 10-30 Pa. When the system stops running, the resistance of the mine is increased by 45-50 Pa. The results are in good agreement with the numerical simulation results, so the umerical simulation results are validated.
