【摘要】：针对一些煤矿中的倒锥形的矿井回风扩散塔,开展基于倒锥形扩散塔的矿井回风热能利用方式及技术的研究,优化矿井回风热能提取装置。倒锥形扩散塔能够使矿井回风热交换器进出口水温温差保持在较小的数值上,并可降低主要通风机出风口的噪音,减小矿井回风热交换器增加的局部通风阻力。采用理论分析、计算和工程实践相结合,得出以下成果和创新:1针对矿井倒锥形扩散塔形式,开发倒锥形扩散塔回风热能利用工艺,实现倒锥形扩散塔矿井回风热能的有效利用,拓展矿井回风热能利用范围;2优化矿井回风换热器及井筒防冻加热器设计,实现矿井回风热能的深度利用。
[Abstract]:Aiming at the inverted conical mine return air diffuser tower in some coal mines, the research on the utilization mode and technology of the mine return air heat energy based on the inverted cone diffusion tower is carried out. Optimization of the thermal energy extraction device for mine return air. The inverted conical diffuser can keep the temperature difference between the inlet and outlet of the mine return air exchanger at a small value and reduce the noise of the main fan outlet. In order to reduce the local ventilation resistance of mine return air heat exchanger, by combining theoretical analysis, calculation and engineering practice, the following results and innovation 1 are obtained in view of the form of inverted cone diffusion tower in mine. In order to realize the effective utilization of the back air heat energy of the inverted cone diffusion tower mine, to develop the utilization technology of the back air heat energy of the inverted cone diffuser tower, and to expand the utilization range of the back air heat energy in the mine shaft, the design of the mine return air heat exchanger and the wellbore antifreeze heater is optimized. To realize the deep utilization of the heat energy of the return air in the mine.
