矿井回风余热在平煤三矿的应用

平煤神马集团三矿针对矿井回风中丰富的热源,采用热泵技术提取其中的热量,为工业广场内建筑冬季供暖、井筒防冻、夏季制冷,并为洗浴热水提供热源,从而取消燃煤锅炉,减少了污染物排放量;介绍了该技术的原理及特点,根据所需热负荷,提出了实施方案。

Utilization of the residue heat in the returnedair at Pingmei #3 Mine

Aiming at the abundant heat source in the returned air of #3 Mine of Pingmei Shenma Group,its heat content was extracted by use of the heat-pump technique for: supplying heat to the building within industrial site in winter,anti-freezing within shaft,refrigerating in summer,and supplying heat for bathing;thus,the coal-fired boilers omitted,pollutant emission decreased;introduced are the working principle and special feature of this technique;option of its realization proposed based on the calculation of heat load needed.
