Application analysis of capillary heat exchangers in in-situ leaching of uranium

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.
