The ultra-long gravity heat pipe heat-taking section 3 with steam-water separation is directly connected to the bottom of the geothermal well 13, and geothermal energy of the geothermal well 13 is transferred to the heat-taking section 3. Some heat conducting filler can be filled between the heat extraction section 3 and the geothermal well 13 to increase the heat transfer effect. Working medium liquid in the porous core layer 11 on the wall surface of the heat taking section 3 is heated and evaporated to generate working medium steam. The entrained liquid vapour rises to the adiabatic section 2. And a steam-water separation device is arranged at the joint of the heat insulation section 2 and the heat taking section 3. The middle of the inlet of the steam-water separation structure is provided with a gas guide tube 20 and a baffle 9. The steam is divided into two paths, and one path enters the upper-stage baffle 9 and the lower-stage corrugated plate 8 through the air guide tube 20 and the diversion exchange tube 10. The other path firstly passes through the baffle 9 and then enters the upper stage air duct 20 through the diversion exchange tube 10. The steam entering each layer of baffle 9 after branching is about half of the original steam, the steam flow speed is reduced, and the resistance of the steam-water separation equipment is reduced. More layers can also be provided in this manner to further reduce the steam flow rate. One or more layers of baffles 9 are arranged, so that liquid drops with liquid vapor are captured through collision, and the multilayer structure is favorable for reducing the drop falling and hanging amount of the liquid drops. The following corrugated plates 8 are respectively trapped and separated by the inertial force of the liquid and the vapor. Other droplet trapping and separation techniques may be used instead of using a combination of baffles and corrugated plates. A flow guide exchange tube 10 is arranged between the two layers of steam-water separation structures, so that the outside steam flows to the middle, and the middle steam flows to the outside. The inner pipe wall of the heat insulation section is provided with a liquid guide pipe or a liquid guide layer 6 for the liquid condensed from the upper heat exchange section 1 to flow, thereby reducing the amount of vapor carrying liquid drops. A guide plate 5 is arranged at the joint of the heat exchange section 1 and the heat insulation section 2, liquid condensed by the upper heat exchange tube 4 flows to a liquid guide tube or a liquid guide layer 6 through the guide plate 5, and a hole is formed in the middle of the guide plate 5 to allow steam to pass through smoothly. The baffle 5 may be provided with channels opening upwards to prevent vapour carrying over the droplet volume. A plurality of layers of flow guide plates 5 can be arranged, and holes are staggered in the middle to prevent condensate from directly falling. The heat exchange tube 4 transfers the heat obtained from the bottom to other working mediums such as steam and the like. The heat exchange tube 4 can also be omitted to collect the steam and directly push the steam turbine to do work, and the liquid condensed from the steam after doing work is directly sent to the liquid guide tube or the liquid guide layer 6.

The liquid storage tank 16 stores working medium liquid 17, and meanwhile, the working medium liquid 17 can be added into the liquid storage tank 16 through the feed valve 15. The liquid storage tank 16 inputs working medium to the liquid guide pipe or liquid guide layer 6 through the liquid inlet pipe 19 by the check valve or the pump 23, and the whole working medium circulation is completed. The one-way valve or pump 23 can be opened to increase the circulating power in case of insufficient circulating power of the heat pipe. Except that the heat-insulating layer 7 of heat-insulating material is arranged between the inner wall surface above the upper geothermal well 13 and the heat pipe and on the outer surface of the ascending pipe 21 at the temperature lower than the designed working temperature, so that the heat dissipation loss is reduced.
