| 摘 要： | 如何实现地热资源合理开发、高效利用,实现地热资源采灌均衡可持续开发利用模式已成为地热资源开发利用地区重点研究内容。该文根据庆云县某典型小区(以下简称小区A)一个采暖季的开采、回灌监测数据,总结了水温、开采量、回灌量、水位及回灌率变化情况。通过数据分析及调查可知,庆云县回灌工程普遍存在地热尾水温度偏高、热利用效率偏低、地热尾水直接回灌引起管道腐蚀影响供暖效果等问题。针对地板辐射和暖气片采暖两种模式提出了换热技术和增加热泵机组的改进措施建议,既可提高热利用效率,又可保证供暖效果避免设备腐蚀,对庆云县地热供暖工程的升级改造具有一定的指导意义。

| Abstract: | How to realize rational development and efficient utilization of geothermal resources and realize the balanced and sustainable development and utilization mode of geothermal resources is the key in geothermal resources development and utilization areas. Based on monitoring data of mining and recharge in a typical residential district of Qingyun county (hereinafter referred to as area A) during a heating season, the changes of water temperature, exploitation amount, recharge amount, water level and recharge rate have been summarized in this paper. Through data analysis and investigation, it is regarded that there are many problems in Qingyun recharge project, such as high temperature of geothermal tail water, low efficiency of heat utilization, pipeline corrosion caused by direct recharge of geothermal tail water. In view of the two modes of floor radiation and heating with heating sheets, some suggestions for improving heat transfer technology and increasing heat pump units have been put forward. It can not only improve the heat utilization efficiency, but also ensure the heating effect and avoid equipment corrosion. It has certain guiding significance for upgrading and renovating the geothermal heating project in Qingyun county. |
