Description

Technical Field

[0001] This utility model relates to the technical field of geothermal energy water filtration equipment, specifically to a geothermal energy circulating water filtration device. Background Technology

[0002] The Earth's interior contains immense thermal energy, with internal temperatures reaching as high as 7000℃. As depth changes, the temperature decreases to 650-1200℃ at depths of 80 to 100 kilometers. Notably, the Earth's interior contains flowing groundwater and lava flows towards the surface, with lava reaching depths of 1 to 5 kilometers in the Earth's crust. This geological activity allows heat to be transferred from the Earth's interior to areas closer to the surface. Specifically, the high-temperature lava heats nearby groundwater, which, under certain conditions, seeps to the surface, providing a potential heat source for geothermal energy utilization.

[0003] In the application of geothermal energy, the most common and cost-effective method is to directly obtain heat from the Earth's interior through specific means and extract energy for use. Water plays a crucial role as the medium in this process. Specifically, ground source heat pumps are a widely used geothermal energy technology. Their operation primarily utilizes circulating water to transfer heat from underground to the surface, enabling people to utilize this heat.

[0004] However, existing geothermal energy utilization technologies, especially ground source heat pump technology, face a significant problem in practical applications. Since ground source heat pumps rely on the flow of groundwater within the unit for heat transfer, this groundwater inevitably contains various impurities. These impurities negatively impact the normal operation of the unit as the groundwater flows through it, leading to a decrease in the efficiency of the ground source heat pump. This reduced efficiency severely affects the overall efficiency of geothermal energy applications, becoming a major technical obstacle to the efficient utilization of geothermal energy. Therefore, a circulating water filtration device for geothermal energy is urgently needed. Utility Model Content
