[0050] Example 1

[0052] The reaction chamber subsystem 1 provides the system with a place for the lunar soil oxygen production reaction. The reaction chamber subsystem 1 includes a reaction chamber shell 11 and a reaction chamber inner cavity 12. The reaction chamber inner cavity 12 is arranged in the reaction chamber shell 11. Between the reaction chamber shell 11 and the reaction chamber inner cavity 12 is a working medium cavity for filling the heat transfer medium 25. That is, the heat transfer medium 25 is heated in the working medium cavity to provide heat energy for the reaction chamber inner cavity 12.

The heating subsystem 2 also includes a heat pipe 24, a circulation pump 26 and a reflector 22. The heat pipe 24 connects the circulation pump 26, the heat absorber 23 and the working medium chamber to form a loop.

[0054] The feeding and slag discharge subsystem 3 includes a feeding bin 31 and a slag bin 34, both of which are connected to the inner chamber 12 of the reaction chamber subsystem 1, and continuously supply lunar soil raw materials and discharge slag materials to the lunar soil oxygen production reactor system; the feeding bin 31 is arranged directly above the inner chamber 12 of the reaction chamber, and is connected to the inner chamber 12 of the reaction chamber, and continuously supplies lunar soil raw materials to the inner chamber 12 of the reaction chamber by gravity; the slag bin 34 is arranged directly below the inner chamber 12 of the reaction chamber, and is connected to the inner chamber 12 of the reaction chamber, and continuously discharges slag materials by gravity. A feeding valve 32 and a discharging valve 33 are respectively provided at the inlet and outlet ends of the feeding bin 31; a slag feeding valve 35 and a slag discharging valve 36 are provided at the inlet and outlet ends of the slag bin 34.

[0055] The gas supply and exhaust subsystem 4 is used to continuously supply reaction gas and exhaust product gas to the lunar soil oxygen production reactor system. The gas supply and exhaust subsystem 4 includes an intake valve 41, an exhaust valve 42 and a gas pipeline 43. The intake valve 41 is arranged at the lower part of the reaction chamber subsystem 1, and the exhaust valve 42 is arranged at the upper part of the reaction chamber subsystem 1, that is, the reaction gas flows from bottom to top in the reaction chamber inner cavity 12 by the pressure difference.

[0056] The control subsystem 5 is used to control the heat energy supply, lunar soil raw material supply and slag material discharge, and gas supply and discharge of the lunar soil oxygen production reactor system. The control subsystem 5 includes a single-chip microcomputer controller 54, a thermocouple 52, a gas pressure gauge 51, and a piezoelectric sensor 53. The air inlet valve 41, the exhaust valve 42, the feed valve 32, the discharge valve 33, the slag inlet valve 35, and the slag discharge valve 36 are electrically connected to the single-chip microcomputer controller 54. The thermocouple 52, the gas pressure gauge 51, and the piezoelectric sensor 53 are all electrically connected to the single-chip microcomputer controller 54.

[0057] The heating subsystem 2 is also equipped with a director 21 , which is controlled by a single-chip controller 54 to point to the sun, and reflects and converges sunlight onto the heat absorber 23 .

[0058] The feed valve 32, the discharge valve 33, the slag feed valve 35 and the slag discharge valve 36 are all equipped with a servo motor 55, and any servo motor 55 is electrically connected to the single-chip controller 54, so as to realize automatic control of the feed valve 32, the discharge valve 33, the slag feed valve 35 and the slag discharge valve 36. It can be understood that any part involving switches in the lunar soil oxygen production reactor system of the present invention can be automatically controlled by the single-chip controller 54.

[0059] A heat insulating layer 13 is provided on the outer surface of the reaction chamber shell 11. A support 14 is also provided on the reaction chamber shell 11.

[0060] like Figure 2As shown, the inner cavity 12 of the reaction chamber is a plurality of interconnected hourglass-shaped reaction chambers, which adopt a conical structure or a hemispherical structure, the number of which is 1 to 100 pairs, and the volume of the inner cavity 12 of the reaction chamber in the shell 11 of the reaction chamber is 10 to 90%, and the arrangement of the conical structure or the hemispherical structure is coaxial arrangement and / or parallel axis arrangement. The lunar soil raw material flows downward from the feed bin 31 at the top of the reaction chamber through the inner cavity 12 of the reaction chamber, reacts with the reaction gas in the inner cavity 12 of the reaction chamber, and then is converted into slag and flows into the slag bin 34 at the bottom of the reaction chamber 1.

[0061] In addition, the hourglass-shaped reaction chamber can also adopt other polyhedral cones, such as triangular pyramids, quadrangular pyramids, etc. Of course, other structures that can delay or slowly discharge materials can also be used.

[0062] like Figure 4 As shown, Figure 4 The schematic diagram of the energy flow path of the present invention. The present invention uses solar thermal conversion technology to convert solar energy into thermal energy. First, the reflector 22 points to the sun under the control of the director 21, reflects and focuses the sunlight on the absorber 23, and the absorber 23 converts the sunlight energy into the thermal energy of the heat transfer medium 25. The heat transfer medium 25 carries the heat energy and is transported to the working medium cavity between the reaction chamber shell 11 and the reaction chamber inner cavity 12 under the action of the circulation pump 26, thereby transferring the heat energy to the lunar soil and reaction gas in the reaction chamber inner cavity 12, providing heat energy for the lunar soil oxygen production reaction, and solving the problem of high energy consumption.

[0063] like Figure 5 As shown, Figure 5 The figure is a schematic diagram of the flow path of the lunar soil and slag of the present invention. The present invention adopts a feed bin 31 and a slag bin 34 with transition bin characteristics, which are respectively arranged directly above and directly below the inner cavity 12 of the reaction chamber. The feed valve 32 of the feed bin 31 is opened to load the lunar soil raw material into the feed bin 31, and then the feed valve 32 of the feed bin 31 is closed to maintain the air pressure in the inner cavity 12 of the reaction chamber, and then the discharge valve 33 of the feed bin 31 is opened to allow the lunar soil raw material to gradually flow into the inner cavity 12 of the reaction chamber. The continuous supply of lunar soil is achieved by opening and closing the feed valve 32 and the discharge valve 33 of the feed bin 31 in sequence, while the pressure in the inner cavity 12 of the reaction chamber is kept stable. Similarly, the continuous discharge of slag is achieved by opening and closing the slag inlet valve 35 and the slag outlet valve 36 of the slag bin 34 in sequence, while the air pressure in the inner cavity 12 of the reaction chamber is kept stable, thereby achieving continuous production of the lunar soil oxygen production system.

[0064] like Figure 6 As shown, Figure 6The present invention uses the gas supply and exhaust subsystem 4 to adjust the gas pressure in the reaction chamber inner cavity 12, connects the gas inlet valve 41 and the exhaust valve 42 to the reaction chamber inner cavity 12 through the gas pipe 43, and uses the gas inlet valve 41 and the exhaust valve 42 to regulate the entry of the reaction gas and the discharge of the product gas to achieve the stability of the reaction pressure.

[0065] The present invention adopts the reaction chamber inner cavity 12 with an hourglass-shaped structure. The lunar soil raw material flows from top to bottom in the reaction chamber inner cavity 12 under the action of lunar surface gravity, and the reaction gas flows from bottom to top in the reaction chamber inner cavity 12 under the action of pressure difference. The lunar soil raw material forms an hourglass phenomenon at the connection point of the middle and top vertices of the hourglass-shaped structure, which slows down the falling speed of the lunar soil particles, increases the contact area between the lunar soil raw material particles and the reaction gas, and improves the reaction rate; at the same time, the reaction time of the lunar soil raw material particles and the reaction gas in the reaction chamber inner cavity 12 is extended, so that the reactants react fully, thereby improving the reaction conversion rate.

[0066] The control subsystem 5 of the present invention at least includes a gas pressure gauge 51, a thermocouple 52, a piezoelectric sensor 53, a single-chip microcomputer controller 54 and a servo motor 55. The control subsystem 5 measures the gas pressure in the inner cavity 12 of the reaction chamber through the gas pressure gauge 51, and the single-chip microcomputer controller 54 controls the corresponding devices of the gas supply and exhaust subsystem according to the gas pressure in the inner cavity 12 of the reaction chamber to maintain the gas pressure in the inner cavity 12 of the reaction chamber, that is, the intake flow rate and the exhaust flow rate are regulated by the intake valve 41 and the exhaust valve 42; similarly, the control subsystem 5 measures the temperature in the inner cavity 12 of the reaction chamber through the thermocouple 52, and the single-chip microcomputer controller 54 controls the corresponding devices of the heating subsystem according to the temperature in the inner cavity 12 of the reaction chamber to maintain the temperature in the inner cavity 12 of the reaction chamber, such as regulating the flow rate of the heat transfer medium 25 through the circulation pump 26, or when rapid cooling / turning off is required. When the device is closed, the angle of the orienter is controlled; the control subsystem 5 measures the mass of the lunar soil raw material in the feed bin 31 and the mass of the slag in the slag bin 34 through the piezoelectric sensor 53, and the single-chip controller 54 controls the feed valve 32 and the discharge valve 33 of the feed bin 31 according to the mass of the lunar soil raw material in the feed bin 31, and regulates the discharge (feeding to the inner cavity 12 of the reaction chamber) and the replenishment (replenishment to the feed bin 31) of the lunar soil raw material; the single-chip controller 54 controls the slag inlet valve 35 and the slag discharge valve 36 of the slag bin 34 according to the mass of the slag, and regulates the slag discharge (slag discharge from the inner cavity 12 of the reaction chamber to the slag bin 34) and slag discharge (slag discharge from the slag bin 34 to the outside).

[0067] The reaction chamber subsystem 1 of the present invention is where the lunar soil oxygen production reaction occurs. The bracket 14 provides stable support, the insulation layer 13 reduces heat loss, the reaction chamber shell 11 and the reaction chamber inner cavity 12 constitute the environment in which the reaction occurs. The reaction chamber subsystem 1 is responsible for monitoring and regulating the entire oxygen production process to ensure that the reaction is carried out under optimal conditions.

[0068] Example 2

[0069] The present invention provides a lunar soil oxygen production reactor system, which includes a reaction chamber subsystem 1, a heating subsystem 2, a material supply and slag removal subsystem 3, a gas supply and exhaust subsystem 4 and a control subsystem 5.

[0070] The reaction chamber subsystem 1 provides a lunar soil oxygen production reaction site for the system, and the reaction chamber subsystem 1 includes a reaction chamber shell 11 and a reaction chamber inner cavity 12. Except for the structure of the reaction chamber inner cavity 12, the other structures are the same as those of Example 1.

[0071] The inner cavity 12 of the reaction chamber is a plurality of interconnected spiral tubes, the number of the spiral tubes is 1 to 100 groups, the volume of the inner cavity 12 of the reaction chamber accounts for 10 to 90% of the reaction chamber shell 11, and the arrangement of the spiral tubes is coaxial arrangement and / or parallel axis arrangement. The lunar soil material flows downward from the feed bin 31 at the top of the reaction chamber through the inner cavity 12 of the reaction chamber, reacts with the reaction gas in the inner cavity 12 of the reaction chamber, and then is converted into slag and flows into the slag bin 34 at the bottom of the reaction chamber.
