Problems solved by technology

Collecting heat requires a certain amount of power consumption, increasing system power consumption and reducing system efficiency
Due to the characteristics of the heat pipe itself, there are heat transfer limits such as the carrying limit and the capillary limit, and there is a transmission length limit, so it is impossible to make an unpowered auxiliary heat pipe that is too long

Embodiment 1

[0034] figure 1 It is a schematic diagram of the device of Example 1 of the present invention. The heat extraction section 3 of the ultra-long gravity heat pipe with steam-water separation is directly to the bottom of the geothermal well 13, and the geothermal energy of the geothermal well 13 is transferred to the heat extraction section 3. Some thermally conductive fillers can be filled between the heat extraction section 3 and the geothermal well 13 to increase the heat transfer effect. The working fluid contained in the porous core layer 11 on the wall of the heating section 3 is heated and evaporated to generate working fluid vapor. The liquid vapor rises to reach the adiabatic section 2. A steam-water separation device is provided at the junction of the adiabatic section 2 and the heat-taking section 3. An air duct 20 and a baffle 9 are arranged in the middle of the inlet of the steam-water separation structure. The steam is divided into two paths, one way enters the up...

Abstract

The invention discloses an ultra-long gravity heat pipe geothermal mining device with a steam-water separation function. A steam-water separation device is arranged between a heat taking section and aheat insulating section, thus the liquid carrying amount of ascending working medium steam is greatly decreased, and the air flow speed is decreased; in addition, descending liquid is collected through a flow guiding plate structure and the like, and thus intersection of ascending gas and descending gas is avoided; and meanwhile, the density difference of the ascending steam and the descending working medium liquid is increased, driving force is increased because of increase of the working medium liquid density difference to be sufficient to overcome increased resistance of the steam-water separation device, and thus the capability of pipe heat length conveying is improved.

Description

Technical field [0001] The invention relates to the technical field of geothermal exploitation, in particular to an ultra-long gravity heat pipe geothermal exploitation device with steam-water separation. Background technique [0002] Geothermal is the thermal energy produced by the thermonuclear reaction of long-lived radioisotopes in the earth's interior and is transmitted to the crust through the high-temperature magma of the earth's envelope. This deep geothermal energy source is inexhaustible and inexhaustible. This kind of geothermal energy generally exists in the following different temperature layers from the outside to the core: the outer thermal layer on the surface of the earth's crust is affected by the atmospheric environment and solar radiation, and at the lower boundary of the outer thermal layer, the temperature does not change at a certain depth. Normal temperature layer; below the normal temperature layer, due to the influence of the earth's internal heat source...
