Technical Field

The invention relates to a geothermal device, in particular to a geothermal energy collecting device.

Background

Geothermal energy is natural energy extracted from the crust of the earth, and compared with the prior art, the geothermal energy belongs to new energy sources, and is very environment-friendly and energy-saving.

The geothermal energy is collected in various ways, such as directly collecting and pumping hot water and gas after directly filling water or other fluids into the ground, generating flash evaporation effect due to pressure change to generate steam, using the steam for power generation, then continuously filling the steam into the system in a direct contact manner, performing in-pipe phase change circulation on the water or other fluids through closed circulation, and pushing other converted indirect heat conduction types of turbine power generation and the like. For the indirect heat conduction type, energy loss exists certainly, and the adopted heat exchanger needs to be replaced after being used for a long time, and the replacement is very troublesome because the heat exchanger is arranged at the bottom of the ground. In direct contact, the hot water sucked out must carry impurities on the ground, since it absorbs the water directly from the ground, and if it enters the subsequent equipment directly, it will cause irreversible damage to the equipment.
