刘店煤矿余热资源热泵供热方案

Heat Pump Heating Scheme With Low-grade Waste Heat in Liudian Mine

针对刘店煤矿在生产中需要供热、同时排放大量低品位余废热量的情况,进行了场区可用余热资源及供热负荷状况调查与分析。根据调研结论,提出了余热资源回收与利用的5套可行性方案,通过定性分析及综合评分法比较,确定了适合于该矿的综合热泵供热方案。该供热方案以矿井回风为主要余热源、以矿井排水和矿井降温冷凝热为备用热源、以空气压缩机冷却余热专门用于洗浴全年加热,从而使系统具有充足的备用热源和良好的扩容能力,提高了供热系统的稳定性和可靠性,降低了初期投资。

According to heating needs and emitting large quantities of low - grade waste heat simultaneously during production in Liudian Mine, the heating load and waste heat resources are surveyed and analyzed. Based on the research conclusions, five feasibility schemes of waste heat recovery and utilization are put forward. And then, the integrated heat pump heating scheme which may be more suited to Liudian Mine is determined by qualitative analysis and comprehensive scoring method. In this heating scheme, the mine ventilation is used as main heat source, the mine drainage and mine cooling condensation heat are used as backup heat source, and the air compressor waste heat in cooling is specially used for heating bath water in the whole year, therefore this scheme has sufficient backup heat sources and good expansion ability. And its stability and reliability is improved, the initial investment is also reduced.
