矿井水、回(乏)风作工业和民用热(冷)能的可行性分析

Feasibility Analysis of Mine Water and Mine Return (Exhaust) Wind Energy Being Used As Industrial and Commercial Hot (Cold) Energy

井下水、回(乏)风是伴随煤矿整个开采过程但并未被充分利用的自然资源,是煤炭生产过程中的伴生能源。煤矿井下水一般水温在10℃,矿井回风一般温度在14℃以上。通过热泵技术提取其中7℃左右温差的热能,将这部分低温热能搬移、压缩,温度提升至80℃左右,变成高温热能,用于供热和其他用途。根据热泵技术专利开发的风源热泵和水源热泵属无污染的清洁能源设备,成为国家推广的环保节能产品,技术成熟,在河北、山东等地被广泛应用推广。对此项技术在大同煤矿集团公司的应用进行了可行性分析。

Mine water and mine return （exhaust） resources which are not taken full advantage of , and th wind throughout the coal mining process are the natural ey are the associated energy during coal production process Coal mine water temperature is generally at 10℃, and mine return wind temperature is generally at 14℃. Through the heat pump technology extraction with 7℃ or so heat energy, with flitting and compression this part of the low temperature heat, temperature will be raised up to 80℃ or so and will become a high temperature heat energy which will be used for heating and other purposes. According to the heat pump technology patent, wind source heat pump and water source heat pump which are pollution-free clean energy equipment have been made, and they have become the national promotion environmental protection and energy saving products. This mature technology has been widely used promotion in Hebei and Shandong. The paper has technology in the Datong Coal Mine Group Company made the feasibility analysis of the application of this technology in the Datong Coal Mine Group Company.
