Geothermal energy is a kind of sustainable renewable and clean resources. However, when using this energy source, there are serious problems such as excessive tail water discharge and insufficient utilization of geothermal energy. Especially in rural areas, how to use geothermal energy at low cost and efficiently is an urgent problem to be solved. The use of geothermal cascade can reduce the temperature of tail water to a certain extent, make full use of geothermal energy in each temperature section, and increase the utilization rate of geothermal energy. Based on the research status of geothermal cascade utilization at home and abroad, this paper proposes a new type of rural geothermal cascade utilization system, and attempts to analyse this system, and finds that this system can increase the utilization rate of geothermal energy at low cost.
