深层地热能多梯级利用的应用研究
|
摘要
当前,深层地热能在应用过程中温差小、模式单一,造成严重的资源浪费和环境污染。以实际供暖案例设计了河南某县深层地热能多级梯级利用的方案。在满足"温度匹配,多梯级利用"的原则下,扩大地热能可利用温差,尽可能减少地热水开采量,提高深层地热能的利用效率。为深层地热能多梯级利用提供设计优化建议,并为其在中部地区推广应用提供指导。逐步改变河南省冬季供暖能源结构,最终达到清洁供暖,减少雾霾影响,有效地改善环境污染问题。
At present, the deep geothermal energy in the application process has a small temperature difference and a single model, resulting in serious resource waste and environmental pollution.Based on the actual heating cases, this paper designs the scheme of multistage utilization of deep geothermal energy in a county in henan province.Under the principle of "temperature match and multi-stage utilization", the available temperature difference of geothermal energy is enlarged, the amount of geothermal water is reduced as far as possible, and the utilization efficiency of deep geothermal energy is improved.It provides design optimization suggestions for the multi-step utilization of deep geothermal energy and provides guidance for its promotion and application in central regions.The energy structure of heating in winter in henan province is gradually changed to achieve clean heating and reduce haze effectively to improve environmental pollution.
