Problems solved by technology

[0003] The use of geothermal energy in the prior art is to use underground hot water in different seasons, extract the underground hot water for heating in winter, and discharge the water source back in summer, but this kind of energy utilization measures makes the regional distribution of geothermal energy uneven, which is easy to cause environmental disasters
[0004] At the same time, this energy utilization method requires a lot of expensive additional equipment as support, and the energy utilization cost is relatively high.

Embodiment 1

[0026] Set a heat-gathering cabin 5 with a length of about 20m, a width of about 6m, and a depth of about 10m on the ground, set a heat-gathering structure in the heat-gathering cabin 5, and erect an upright convection pipe or a convection tower above the heat-gathering cabin 5 to form a convection channel 1. Make the upper and lower openings of the convection channel 1 form a height difference of tens of meters to thousands of meters.

[0027] Wherein, an insulating layer 2 is arranged on the side wall of the convection channel 1, and an insulating layer is arranged outside the insulating layer 2 in order to reduce heat energy loss. Due to the heat insulation of the side wall of the convection channel 1 , the temperature of the air inside and outside the tube at the same height changes asynchronously, forming a convective wind in the convection channel 1 .

[0028] The convection channel 1 is provided with an energy utilization device, such as a power generation fan 3, which ...

Embodiment 2

[0033] On the basis of Example 1, in order to make full use of geothermal energy, the following improvements are made. Multiple geothermal wells 8 are drilled in the heat-gathering cabin 5, and on the side of the heat-gathering cabin 5 close to the ground, there are corresponding ventilation space.

[0034] Specifically, the geothermal well 8 reaches the underground hot water area 7, and an air extraction pipeline is installed in the geothermal well 8. One end of the air extraction pipeline is communicated with the gas source, and the other end extends from the bottom of the geothermal well 8 to the heat gathering area. The upper part of the cabin 5 forms a heat source air outlet, which communicates with the convection channel 1, and the middle section of the air extraction pipeline is located in the underground hot water 7 zone.

[0035] As a preference, one end of the air extraction pipe connected to the air source is arranged parallel to or at a certain angle with the botto...

Abstract

The invention provides an air-ground temperature difference utilization system and method, and relates to the field of new energy. The system comprises a convection channel, a temperature compensationstructure and an energy utilization device; the convection channel communicates with a geothermal source and a high-altitude low temperature area; the temperature compensation structure is connectedwith the convection channel; the energy utilization device is connected with an output end of the convection channel; and an insulation structure is arranged on the convection channel. The convectionchannel is built between the geothermal source and the high-altitude low temperature area; the temperature difference is used for converting geothermal energy to wind energy, so that the geothermal source is utilized more effectively; and meanwhile, as ground source heat and high-altitude cold are natural phenomenon, the system can be sustainable, and is lower in damage to the environment, wider application fields are achieved.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a system and method for utilizing temperature difference between ground and air. Background technique [0002] New energy is an emerging direction of energy utilization today, and wind energy, solar energy, tidal energy, and geothermal energy are all gradually being developed and utilized. [0003] The use of geothermal energy in the prior art is to use underground hot water in different seasons, extract the underground hot water for heating in winter, and discharge the water source back in summer, but this kind of energy utilization measures makes the regional distribution of geothermal energy uneven, which is easy to cause environmental disasters . [0004] At the same time, this energy utilization method needs a lot of expensive additional equipment as support, and the energy utilization cost is relatively high. Contents of the invention [0005] Aiming at the above-m...
