摘要
研究地热水多元梯级综合利用的技术模式。地热水多元梯级综合利用模式中包括低温辐射采暖技术、热泵技术、新型板式换热技术和地热水回灌等新技术。根据地热水的水量、温度、供暖负荷、用水负荷和现场具体条件,因地制宜、合理地确定方案,多种采暖方式可以并存,也可以串联或并串联交叉形成梯级采暖。应用自控技术及其他技术手段最大限度地利用热能,尽可能降低尾水温度和减少尾水排放。四个地热水综合利用实例应用证明地热水多元梯级综合利用模式科学合理。
The multiform cascade comprehensive utilization mode of geothermal water is investigated.The advanced technologies are applied in the utilization mode,such as low-temperature radiant heating technology,heat pump technology,new plate heat exchanger technology,reinjection technology,etc.Based on well considering geothermal water flux,water temperature,water quality,heating load,water usage and water using way,etc.the flowsheet is reasonably made according to the local circumstances,a variety of heating methods can coexist, or form a cascade heating with cross-series or parallel series. Automatic control technology and other technical means are applied to maximize the use of thermal energy, reduce the tail water temperature and reduce the tail water discharge as far as possible. It is proven by four application examples of geothermal water that the multiform cascade comprehensive utilization mode of geothermal water is scientifically reasonable.
