            摘要:

            針對含有地熱能的地浸液水質差、腐蝕性強的特點,提出將毛細管換熱器作為水源熱泵系統的前端換熱器。分析了毛細管換熱器在集液池中換熱的傳熱模型及適用公式,給出了毛細管換熱器的管內水流速度及單位管長傳熱系數范圍。對某地浸采鈾工程進行了可行性分析。效益分析表明,以毛細管換熱器作為前端換熱器的水源熱泵系統高效節能、前景可期

            Abstract:

            In view of the poor water quality and strong corrosiveness of in-situ immersion liquid containing geothermal energy, proposes a capillary heat exchanger as the front-end heat exchanger of the water-source heat pump system. Analyses the heat transfer model and applicable formula of the capillary heat exchanger in the sump, and gives the water flow velocity in the tube and the range of the heat transfer coefficient per tube length of the capillary heat exchanger. Carries out a feasibility analysis of an in-situ leaching uranium mining project. The benefit analysis shows that the water-source heat pump system with capillary heat exchanger as the front-end heat exchanger is highly efficient and energy-saving, and has a promising future.
