摘要
为充分利用矿井乏风余热,采用Ansys软件建立对流换热模型,对煤矿回风井余热回收装置的附加阻力、换热效率、内部流场的变化和影响因素进行了分析研究。结论表明:回风井口的风流速度越大,装置的换热效率越低。
In order to make full use of the lack of wind, the Ansys software is used to establish a convection heat transfer model, and the additional resistance, heat transfer efficiency, and influencing factors of the internal flow field of the coal mine return. Conclusion shows that the larger the wind flow speed of the returning wellhead, the lower the heat exchange efficiency of the device.
