摘要:

文章在详细分析国内外矿井热害治理理论和措施的基础上,总结出高温矿井热害的根源,归纳了热害治理的技术方法,提出利用极细雾粒相变的吸热来进行降温的方法。运用流体力学软件FLUENT对降温设备进行数值模拟,得出:30℃的热风经过设备的降温后变为20℃~22℃的风流,温度下降了8℃~10℃,符合矿井降温的要求,有利于我国煤矿绿色开采的研究。

Abstract:

This paper based on analyzes the theory and control measures of mine heat damage at home and abroad in detail, summarizes the source of heat damage and the control technology of heat damage. The basic mechanism of phase-change cooling of very fine mist is introduced. Numerical simulation of the local spray cooling equipment obtained: 30℃ hot air after cooling equipment into a 20℃~22℃ air flow,and the temperature decreased by 8℃~10℃, in line with the cooling requirements of the mine. So this kind of equipment is promoted the use of study on Green coal mining technology.

Key words: heat damage of mines, phase-change cooling, simulation research
