Problems solved by technology

[0016] 3) The auxiliary control system is complex
[0017] 4) If natural gas, crude oil and coal gas are used as fuel, the fuel cell stack will produce carbon dioxide, which will have adverse effects on the environment, such as the "greenhouse effect"
But it still has an adverse impact on the environment when using cheap fuel

Embodiment 1

[0056] Embodiment 1 is a power generation device of a high temperature gas-cooled stack-oxygen concentration difference battery stack direct cycle system using an oxygen separation system. Its structure is as Figure 4 shown. In the figure, 41-high temperature gas-cooled reactor; 42-fan; 43-oxygen separation system; 44-oxygenator; 45-oxygen-helium mixed gas transportation pipeline; 46-oxygen chamber; 47-oxygen concentration battery; 48-card Groove; 49-thermocouple; 410-oxygen chamber wall; 411-temperature control system; 412-insulation layer; 413-shell; 414-preheater. As can be seen from the figure, the high-temperature helium gas coming out from the high-temperature gas-cooled reactor core directly passes through the inner cavity of the oxygen concentration difference battery 47 of the oxygen concentration difference battery stack, and the oxygen concentration difference battery in the oxygen concentration difference battery stack is heated to make the Its temperature reach...

Embodiment 2

[0057] Embodiment 2 is a combined power generation device of a high-temperature gas-cooled stack-oxygen concentration stack direct cycle system using a vacuum pump system. Its structure is as Figure 5 shown. In the figure, 51-high temperature gas-cooled reactor; 52-fan; 53-oxygen concentration difference battery; 54-card slot; 55-steel shell; 56-thermocouple; 57-oxygen chamber wall; 58-temperature control system; 510-vacuum pump; 511-oxygen transport pipeline; 512-oxygen chamber; 513-insulation layer; 514-heat exchange components; 515-oxygen chamber.

[0058] It can be seen from the figure that the high-temperature helium gas coming out of the high-temperature gas-cooled reactor core directly passes through the inner cavity of the heat exchange component 514 in the oxygen chamber, and heats the oxygen concentration cells in the oxygen concentration cell stack to make the temperature reach 500- 1000°C. Part of the oxygen in the oxygen chambers 512 and 515 enters the inner c...

Embodiment 3

[0059] Embodiment 3 is a high temperature gas-cooled stack-oxygen concentration difference battery stack indirect circulation system combined power generation device using an oxygen separation system. Its structure is as Figure 6 shown. In the figure 61-high temperature gas-cooled reactor; 62-fan; 63-heat exchanger; 64-oxygen concentration battery; 65-card slot; 66-thermocouple; 67-oxygen chamber wall; 68-compressor; 69-oxygen Separation system; 610-Oxygen supplement; 611-Oxygen chamber; 612-Temperature control system; 613-Insulation layer; 614-Shell; 615-Preheater.

[0060] The system has two loops. The primary loop consists of a high temperature gas-cooled stack, a fan and a heat exchanger. The oxygen concentration difference battery stack is composed of many oxygen concentration difference batteries connected in series and parallel. The oxygen concentration cell stack is located in the oxygen chamber. The oxygen chamber is composed of the outer wall of the oxygen conc...

Abstract

The present invention belongs to the applicatino of motive electricity generation. High heat source and oxygen concentration cell pile are made to constitute power generator. High temperature heat source produces heat to make the oxygen concentration cells in high temperature working state, and the oxygen concentration cell pile comprising many oxygen concentration cells connected serially and parallelly is inside the oxygen chamber. The oxygen supplying device connected to the oxygen chamber supplies oxygen for the oxygen chamber. The inner cavity of the oxygen concentration cell has lower oxygen pressure in the inner cavity than in the outer cavity. The present invention has high power generating efficiency, less high speed rotating parts, and less environmental pollution.

Description

(1) Technical field: [0001] The invention belongs to the application field of power generation, in particular to the field of nuclear power generation. (two) background technology: [0002] Global warming and acid rain are issues that seriously affect the foundation of human life that the international community is eager to resolve. About 50% of global warming is caused by CO 2 80% of which are caused by burning oil, coal, natural gas and other fossil fuels. Environmental issues are therefore closely related to energy consumption. Nuclear power does not release CO during power generation 2 , has become an important method for humans to switch from petroleum energy to non-petroleum energy. [0003] High-temperature gas-cooled reactor is an advanced nuclear fission reactor developed in the world in recent decades. This type of reactor provides thermal energy at high temperatures through nuclear fission reactions. Due to the use of "full ceramic" coated granular fuel elem...
