Problems solved by technology

However, in addition to the limitation of the land area occupied by the above-ground facilities of the power station, there are other problems: the volume of the heating agent is limited by the flow rate of the rising hot water and the temperature of the above-ground hot water resource
The earth's geothermal resources are very rich, and most of the characteristics show that the double cycle power station can operate successfully, however, due to the existence of these problems, the geothermal power station has not realized its potential

Abstract

The technical outcome of the proposed geothermal energy device is to increase its efficiency (CE), to simplify and cheapen the construction. The geothermal energy device contains downstream and upstream pipes, which are filled with fluid thermal agent and placed in the borehole; they are connected to each other with a heat exchanger in the depth of the borehole. The downstream pipe is equipped with several mechanical non-return valves; on the same pipe there is also installed a down pushing pump of the thermal agent (e.g. isobutane). The end of the upstream pipe on the ground surface is directed towards the condensation type steam turbine, equipped with the controlled (e.g. electromagnetic) valve, and turned towards the mentioned turbine by the Laval nozzle. The energy device additionallycontains the device of the frequency / duration control to lock and unlock the mentioned controlled valve.

Description

technical field [0001] The invention relates to a closed convection double-circulation geothermal energy device, which is used for producing various energies including electric energy. Its main technical effect is to increase the effective coefficient, simplify the construction process and reduce the cost. Background technique [0002] Dual cycle, a thermodynamic cycle utilizing two working fluids, one of which is in a high-pressure environment with a lower saturation pressure and the other with a lower evaporation temperature. The two fluids used in the present invention, one is hot water (or hot gas in dry mines) that exists naturally in deep underground mines, and the other is heating agent, such as isobutylene, which is pumped into the upstream and downstream pipelines at high pressure in a closed loop. The essence of circulation is to extract geothermal energy deep underground to the ground for direct use and / or further conversion into mechanical energy and / or electri...
