浅谈地热能源在供热领域的梯级利用

Brief Discussion on Cascade Utilization of Geothermal Energy in the field of Heat Supply

地热作为一种清洁能源被广泛利用在供热、发电、医疗等领域。但地热资源并非取之不尽、用之不竭,只有科学合理地加以使用,才能保持地热资源的可持续开发利用。本文结合实际工程,介绍了一种地热在供热领域的能源梯级利用方式。通过直燃型吸收式热泵机组回收地热尾水的热量作为供热的热源,将回灌温度降至32.8℃,增加了供热面积,提高了地热能源的综合利用效率。

Geothermal energy, as a clean energy, is widely used in heating, power generation, medical bathing and other fields. However, geothermal resources are not inexhaustible. In order to maintain the sustainable development and utilization of geothermal resources, this paper introduces the cascade utilization of geothermal energy in the field of heating combined with practical projects. Recycling heat from geothermal tail water by direct-fired absorption heat pump unit as heat source reduces the recharge temperature to 32.8℃, and increases the heating area.
