Embodiment 1

[0024] This embodiment provides a thermoelectric power generation method, using cold seawater at a depth of 300-1000 meters as a lower-temperature medium, hot seawater at a depth of 100-200 meters on the ocean surface as a higher-temperature medium, and carbon dioxide as a main working medium for power generation, including the following steps:

[0025] 1) With the help of a higher temperature medium, that is, the extracted higher temperature seawater, the working fluid is heated through heat exchange to make it gasify and rise;

[0026] 2) With the help of a lower temperature medium, that is, the extracted lower temperature seawater, the gasified and rising working medium is cooled through heat exchange to condense it into a liquid state;

[0027] 3) Diversion liquid working medium flows down from a high place, driving the impeller to rotate to generate power;

[0028] 4) divert the concentrated working medium that has done work, and repeat step 1).

[0029] In this embodime...

Embodiment 2

[0053] The temperature difference power generation equipment 1a of this embodiment is mainly used in relatively cold regions. Since the air temperature in cold regions is relatively low, especially in deep winter, the temperature difference between the air at high altitude and the seawater under the sea surface is large, and the temperature difference can be used to generate power. In a specific implementation, the lower end of the thermoelectric power generation equipment 1a is set under the sea surface, and the seawater collected from there is 4-5 degrees Celsius as a relatively high-temperature medium, and the upper end extends to the high altitude, and the air below 0 degrees Celsius in the high altitude is used as the medium. lower temperature media.

[0054] Such as Figure 5 As shown, the principle of the thermoelectric power generation device 1a in this embodiment is the same as that of the thermoelectric power generation method in the first embodiment, and the overall...

Embodiment 3

[0063] The thermoelectric power generation equipment 1b in this embodiment is applied in the deep sea (the depth exceeds 500 meters), and the low-temperature seawater in the deep sea is used as the lower-temperature medium, and the seawater extracted from the shallow sea is used as the higher-temperature medium.

Abstract

The invention relates to the technical field of new energy resources, and discloses a temperature differential power generation method and temperature differential power generation equipment, wherein the temperature differential power generation equipment utilizes temperature difference of a medium, so that a working medium pushes an impeller to rotate to do work and to generate power. The temperature differential power generation equipment comprises a convertible device and a guide tube, wherein an inner cavity for heating the working medium to ascend, a heating structure capable of carrying out heat exchange by virtue of a relatively high temperature medium and a cooling structure capable of carrying out heat exchange by virtue of a relatively low temperature medium are arranged on the inner part of the convertible device; the heating structure is arranged at the lower end of the convertible device; the cooling structure is arranged at the upper end of the convertible device; the guide tube is vertically arranged; the upper end of the guide tube is communicated to the upper part of the inner cavity; the lower end of the guide tube is provided with an impeller cavity; the impeller is arranged in the impeller cavity; and the lower end of the impeller cavity is communicated to the lower part of the inner cavity. The temperature differential power generation equipment utilizes temperature difference of an outer medium, and is matched with pressure intensity control to heat for ascending a gaseous-state working medium and converting the gaseous-state working medium into a liquid-state working medium, so that the impeller is pushed to generate power by utilizing gravitational potential energy carried on the liquid-state working medium, and therefore, the power generation efficiency is high, and the popularization cost is low.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a thermoelectric power generation method and thermoelectric power generation equipment. Background technique [0002] Thermoelectric power generation technology is a cutting-edge power generation technology developed in the exploration of new energy technologies. Its principle is to use the temperature difference of the external medium to make the working medium do work, and finally drive the impeller to rotate to generate electricity. For example, the ocean temperature difference power generation technology provides a huge and very stable cold and heat source for power generation because there is a basically constant temperature difference of 20-25°C between the surface of the ocean in tropical regions and the depth of hundreds to thousands of meters. At present, the theoretical estimated storage capacity of the world's ocean temperature difference energy is 10 billion kilowa...
