煤矿低温热源利用技术研究与应用

Study and Application of Mine Low Temperature Thermal Resources Utilization Technology

针对低温热源蕴藏量大且可再生的特点,在分析国内外低温热源利用现状的基础上,指出了煤矿低温热源利用的优势及存在的问题。根据煤矿各种低温热源的特点,在阐述热泵原理的基础上,研究了矿井回风源热泵技术、电厂冷却水热能回收技术、矿井水热能提取技术。结合煤矿低温热源多种形式并存的特点,提出了煤矿低温热源综合利用技术。冀中能源集团所属矿井的低温热源利用效果表明,煤矿低温热源应用具有广阔的发展前景。

A ccording to the large and regenerated features of the low temperature thermal source reserves, based on the analysis on the utili- zation status of the low temperatures thermal sources at home and abroad, the paper pointed out the advantages and problems existed in the utilization of the mine low temperature thermal sources. According to the features of different low temperature thermal sources in mine, based on the statement of the heat pump principle, the paper had a study on the thermal sources pump technology of mine air retuning sources, thermal recovery technology of cooling water in the electric power plant and thermal recovery technology of mine water.In combina- tion with the multi form existed features of the mine low temperature thermal sources, a comprehensive utilization technology of the mine low temperature thermal sources was provided.The utilization effect in the mines of Jizhong Energy Group showed that the utilization of the mine low temperature thermal energy would have a wide application prospect.
