[0002] At present, there have been some preliminary ideas for base construction in a low - oxygen and high - carbon - dioxide environment. For example, using large - scale oxygen - making equipment to separate oxygen from environmental gases. However, these devices often consume huge amounts of energy, require continuous large - scale external energy input, have limited separation efficiency, are difficult to meet the long - term and stable oxygen demand of the base, and there are also many difficulties in the maintenance and upkeep of the equipment. There are also solutions that attempt to introduce special plants to improve the gas environment, hoping to absorb carbon dioxide and release oxygen through the photosynthesis of plants. However, the harsh low - oxygen and high - carbon - dioxide environment is extremely unfavorable to the growth of plants, the survival rate and growth conditions of plants are difficult to guarantee, and it is difficult to obtain the soil, water and other conditions required for plant growth in this environment, greatly reducing the feasibility of this solution. In addition, regarding energy supply, some ideas are to collect energy by laying a large number of traditional solar panels. However, the lighting conditions in this environment are complex and variable, the efficiency of solar panels is severely affected, and the equipment is easily damaged by environmental erosion, making it difficult to provide stable energy support. Most importantly, these solutions lack systematicness, sustainability, practicality and the ability of energy self - sufficiency, are overly dependent on external materials, have certain environmental risks and technical implementation difficulties, and are difficult to be feasible solutions for constructing a self - sufficient base in a low - oxygen and high - carbon - dioxide environment.

[0028] Example 1

[0029] As Figure 1 and Figure 2As shown in the figure, the system for constructing a self-sufficient base in a hypoxic and hypercapnic environment in this embodiment includes a solar frequency-division concentrating transmission and power generation module 1, a water electrolysis module 2, a carbon dioxide capture and conversion module 3, a geothermal power generation module 4, a nutrient generation module 5, and a base 6; the solar frequency-division concentrating transmission and power generation module 1 is connected to the water electrolysis module 2, the carbon dioxide capture and conversion module 3, and the geothermal power generation module 4, the water electrolysis module 2 is connected to the carbon dioxide capture and conversion module 3, and the carbon dioxide capture and conversion module 3 is connected to the geothermal power generation module 4 and the nutrient generation module 5.

[0030] The solar frequency-division concentrating transmission and power generation module 1 is used to efficiently collect and convert solar energy into electrical energy or heat energy, providing continuous energy support for the base 6. Through the frequency-division concentrating technology, it can maximize the utilization of sunlight resources in the environment; the water electrolysis module 2 uses the electrical energy generated by the system to electrolyze water into oxygen and hydrogen. The oxygen is processed and supplied to the base for breathing, while the hydrogen can be used as an energy reserve or for other chemical reactions; the carbon dioxide capture and conversion module 3 is used to capture carbon dioxide from the atmosphere and convert it into other utilizable resources such as organic substances through chemical processes; the geothermal power generation module 4 uses the geothermal energy underground, with supercritical carbon dioxide as the working medium, to efficiently convert geothermal energy into electrical energy to supply power to the base; the nutrient generation module 5 is used to utilize the available resources in the environment (such as water, carbon dioxide, inorganic salts, etc.) to produce nutrients such as food, vitamins, and minerals through the microbial fermentation process. Through this technology, the recycling of substances can be achieved, reducing the base's dependence on external materials.

[0031] The solar frequency-division concentrating transmission and power generation module 1 includes a condenser 101. The sun's rays are transmitted through the condenser 101 to the frequency-division film 102. The frequency-division film 102 is arranged in front of the solar panel 110. The frequency-division film 102 transmits light within a specific wavelength range to the collector 103, and light of other wavelengths is reflected to the solar panel 110. The frequency-division film 102 is designed using computer-aided automatic numerical calculations, numerical solution methods for optimizing the film system structure using optimization functions, etc. The solar thermoelectric conversion process basically maintains a constant power generation efficiency within the entire wavelength range, while the photovoltaic conversion process has a great correlation with the wavelength. Therefore, the frequency-division film 102 is used to irradiate different ranges of sunlight to the collector 103 and the solar panel 110 respectively to utilize solar energy with the full spectrum.

[0032] The collector 103 is connected to the first turbine 104. The first turbine 104 converts the working fluid into high pressure and exchanges heat with the first heat exchanger 105 to complete the heat exchange process. After the heat-exchanged working fluid enters the first expander 106 to do work, it enters the condenser 108 and is cooled into a liquid. Then the liquid working fluid re-enters the working fluid pump to complete the entire cycle. The electric energy generated by the solar panel 110 and the first generator 107 is converted between AC and DC through the first current regulating device 109. Among them, the solar panel 110 is connected to the storage battery 111 to store the base electric energy.

[0033] The electrolytic water module 2 includes an electrolytic cell 201. A partition 207 is provided in the electrolytic cell 201. One side of the electrolytic cell 201 is connected to the hydrogen storage tank 204, and the other side is connected to the oxygen storage tank 203. The oxygen storage tank 203 is successively connected to the gas storage tank 205 and the supercharger 206. Both the hydrogen storage tank 204 and the gas storage tank 205 are connected to the carbon dioxide capture and conversion module 3. Pour liquid water into the electrolytic cell 201. Under the action of the power supply 202 connected to the electrolytic cell 201, an oxidation reaction occurs in the anode chamber to generate oxygen, and the generated oxygen is stored in the oxygen storage tank 203; a cathode reaction occurs in the cathode chamber to generate hydrogen, and the generated oxygen is stored in the hydrogen storage tank 204. The total reaction chemical formula is 2H2O(l)→2H2(g)+O2(g). Among them, the anode chamber and the cathode chamber are separated by the partition 207. The supercharger 206 removes carbon dioxide gas through the carbon dioxide capture and conversion module 3 for the oxygen and the atmosphere in the gas storage tank 205, adjusts the proportion of each component, and compresses it to an appropriate air pressure (such as 1000-1013 hPa) and then inputs it into the base 6.

[0034] The carbon dioxide capture and conversion module 3 includes a compressor 301, a carbon dioxide capture and release device 302, a buffer tank 303, and a reaction device 304 connected in sequence. The carbon dioxide capture and release device 302 is connected to the gas storage tank 205 and the geothermal power generation module 4. The reaction device 304 is connected to the hydrogen storage tank 204 and the nutrient generation module 5. Use the compressor 301 to extract the carbon dioxide-rich atmosphere and input it into the carbon dioxide capture and release device 302. The carbon dioxide capture and release device 302 contains an adsorbent to capture carbon dioxide and separate it from the air. The carbon dioxide is respectively input into the buffer tank 303 and the second turbine 401 of the geothermal power generation module 4, and the remaining part is input into the gas storage tank 205. Adjust the air pressure and temperature through the reaction device 304, and produce methanol according to the main reaction CO2(g)+3H2(g)→CH3OH(g)+H2O(g). The crude methanol is input into the first separation device 501 of the nutrient generation module 5.

[0035] The geothermal power generation module 4 includes a second turbine 401, a condenser 402, a second expander 404 and a second heat exchanger 403. Part of the carbon dioxide in the outside world is captured by the carbon dioxide capture and release device 302 and input into the connected second turbine 401 to make its pressure reach the supercritical state. The critical temperature of carbon dioxide is 31 °C, and the critical pressure is 7.38 MPa. In the supercritical state, carbon dioxide has high heat transfer efficiency, strong work capacity, and small system circulation loss, and can form supercritical carbon dioxide as the working medium for driving geothermal power generation. The supercritical carbon dioxide obtains geothermal energy through the geothermal unit for heat energy utilization, expands and floats upward in the geothermal layer. The supercritical carbon dioxide that has expanded by heating is extracted, exchanges heat with the second heat exchanger 403 and then enters the second expander 404 to do work, and is cooled in the condenser 402, and then a new cycle is carried out. The work generated in the second expander 404 is converted into electric energy by the second generator 405, and the conversion between alternating current and direct current is realized through the second current regulating device 406.

[0036] The nutrient production module 5 includes a first separation device 501, a flow meter 502, a microbial fermentation device 503, and a second separation device 504 connected in sequence. The first separation device 501 is connected to the reaction device 304, and the raw material methanol is pretreated in the first separation device 501 to ensure the purity and suitability of the fermentation raw materials. The pretreated methanol and the remaining culture raw materials are introduced into the microbial fermentation device 503, and appropriate amounts of seed solutions of Pichia pastoris and Corynebacterium glutamicum with higher fermentation efficiency after genetic modification are inoculated respectively. The feeding rate of nutrients during the fermentation process is controlled by the flow meter 502. When the fermentation time reaches the preset value, the fermentation process is ended, and the fermentation broth is introduced into the second separation device 504 to separate the thallus from the product.

[0037] Example 2

[0038] As Figure 3 shown, the method for constructing a self-sufficient base in a low-oxygen and high-carbon dioxide environment in this embodiment includes the following steps:

[0039] (1) Carry out solar thermal power generation and photovoltaic power generation through solar frequency division concentrating to supply energy for the base;

[0040] (2) Electrolyze water to produce hydrogen and oxygen;

[0043] (5) Use methanol as the main carbon source, and ferment Pichia pastoris and Corynebacterium glutamicum to produce nutrients;

[0044] (6) Sense and adjust the temperature, illumination, and atmosphere inside the base through sensors.

After the signals are transmitted, they are processed and analyzed to determine whether the current environmental parameters meet the preset conditions. When the conditions are not met, the sunshade motor is driven to open or close the sunshade to adjust the illumination; the compressor and the atmosphere proportion adjustment device adjust the atmosphere. The sensors continuously monitor the environmental parameters inside the base and form a closed-loop feedback with the new signals.
