Technical Field
[0001] This invention relates to the field of gas compression and collection technology, and more specifically to a device and method for capturing and compressing the Martian surface atmosphere. Background Technology
[0002] In recent years, as human exploration of space has deepened, research on Mars has become a crucial part of the space exploration strategies of various countries. Limited by current transportation capabilities, the most important aspect of Mars technology is in-situ resource utilization. The Martian atmosphere, containing over 95% carbon dioxide, can be widely used in areas such as carbon dioxide jetting and in-situ oxygen production. Therefore, atmospheric capture technology is particularly important.
[0003] Currently, the most typical atmospheric capture device for the Martian surface is the scroll compressor manufactured by Air Squared, used in the US MOXIE in-situ oxygen production project. However, in the application of carbon dioxide jets, the required pressure is 2-3 orders of magnitude higher than the final pressure in the MOXIE project. Under such operational requirements, a single scroll compressor generates an enormous amount of heat, significantly limiting its performance. Therefore, to develop a capture compressor suitable for Martian carbon dioxide jets, innovation in existing technology is essential. Summary of the Invention

[0008] Preferably, the vortex pump housing has a vortex pump inlet on its side, the fixed plate with built-in cooling channel has three fixed plate inlets, one fixed plate cooling channel inlet, and one fixed plate cooling channel outlet on its side, and the fixed plate with built-in cooling channel has a vortex pump outlet with a one-way valve at the center of its bottom.
[0009] Preferably, the compression chamber with built-in cooling channel has a compression chamber cooling channel inlet, a compression chamber cooling channel outlet, and a plunger pump inlet with a one-way valve on the side, and a plunger pump outlet with a one-way valve at the top center of the compression chamber with built-in cooling channel.
[0010] Preferably, the inlet and outlet of the cooling channel in the fixed plate with built-in cooling channels are located on its side, and the cooling channels surround the fixed plate around its outer ring; the inlet and outlet of the cooling channel in the compression chamber with built-in cooling channels are located on its side, and the cooling channels are arranged between the three pistons.
[0011] Preferably, the Mars atmospheric filtration system is connected to the vortex pump inlet via a piping system, allowing airflow to flow to the three fixed plate inlets. The vortex pump outlet with a one-way valve is connected to the low-pressure tank via a piping system. The low-pressure tank is connected to the plunger pump inlet with a one-way valve via a piping system through the plunger pump housing. The plunger pump outlet with a one-way valve is connected to the high-pressure tank via a piping system through the plunger pump housing.

The compression chamber cooling channel outlet is connected to the high-pressure tank via a piping system through the plunger pump housing and the vacuum radiator.
[0012] A method for capturing and compressing the Martian surface atmosphere, based on the aforementioned Martian surface atmosphere capturing and compressing device, includes the following steps:
[0013] S1: Low-pressure compression step, disengage the clutch, shut off the two vacuum radiators, start the dual-head motor, run the scroll compressor alone, and allow the Martian atmosphere to pass through the Martian atmosphere filtration system and be compressed into the low-pressure storage tank by the scroll compressor.

When the pressure in the high-pressure storage tank reaches a certain level, the two vacuum radiators are turned on to start the heat dissipation circuit. The gas in the high-pressure storage tank flows through one vacuum radiator into the fixed plate of the built-in cooling channel and the compression chamber of the built-in cooling channel, and then flows through the other vacuum radiator back to the high-pressure storage tank. The speed of the dual-head motor is increased to continuously capture and compress the Martian atmosphere and store it in the high-pressure storage tank.
[0016] The beneficial effects of this invention are:
[0017] 1. The new cooling technology allows the cooling medium to flow through the high-temperature parts inside the compressor, significantly improving heat dissipation efficiency compared to traditional scroll compressors and plunger compressors. This ensures the stability of the compressor at high speeds and effectively increases the discharge volume.
[0018] 2. The scheme of using a scroll compressor and a plunger compressor in series fully utilizes the advantages of the scroll compressor's high capture speed and the plunger compressor's large pressure ratio. Compared with the high-performance single compressor scheme, it is more efficient and easier to achieve high capture capacity and high compression ratio.
[0019] 3. The device uses the high-pressure material it captures as a cooling medium. If a cooling pipe leaks, only the leak needs to be repaired to continue using the device. This avoids the device becoming unusable due to the loss of cooling medium. Compared to traditional coolant cooling methods, it does not require carrying a cooling medium, thus reducing the cost of transporting it to Mars.
[0020] 4. The two types of compressors adopt an integrated design, using a single motor to drive both the scroll pump and the plunger pump simultaneously, which simplifies the system structure and effectively reduces the system size compared to simply connecting the two pumps through pipelines.

[0033] The scroll compressor 6 adopts a three-scroll structure design, the plunger compressor 7 adopts a three-piston parallel design, and the scroll compressor 6 and the plunger compressor 7 are connected in series and connected by a dual-head motor 605. One end of the output shaft of the dual-head motor 605 is connected to the plunger compressor 7, and the other end of the output shaft is connected to the scroll compressor 6. The output shaft of the dual-head motor 605 connected to the scroll compressor 6 is an eccentric shaft, adopting an eccentric design structure. The dual-head motor 605 can drive the scroll compressor 6 and the plunger compressor 7 simultaneously.
[0034] The cooling medium for the scroll compressor 6 and the plunger compressor 7 is high-pressure gas or liquid obtained by the atmospheric capture and compression device itself.
[0035] The scroll compressor 6 includes a moving plate 601, a fixed plate 602 with a built-in cooling channel, a scroll pump housing 603, a bearing 604, and a dual-head motor 605; the moving plate 601, the fixed plate 602, the bearing 604, and the dual-head motor 605 are all located inside the scroll pump housing 603.
[0036] The dual-head motor 605 is placed on top of the vortex pump housing 603 and is fixedly connected to the vortex pump housing 603. The lower output shaft of the dual-head motor 605 is connected to the moving plate 601 through the bearing 604.
[0037] The fixed plate 602 with built-in cooling channel is fixedly connected to the lower end of the vortex pump housing 603; the moving plate 601 is adapted to the fixed plate 602 with built-in cooling channel, and the lower output shaft of the dual-head motor 605 drives the moving plate 601 to move, thereby making it move relative to the fixed plate 602 to realize the functions of air intake and exhaust.

The outer edge of the swashplate 702 is engaged with three sliding shoes 703, and the three sliding shoes 703 are fixedly connected to three corresponding pistons 704 respectively. The pistons 704 are adapted to the piston chambers provided in the compression chamber 705. The rotation of the swashplate 702 drives the pistons 704 to reciprocate linearly up and down in the compression chamber 705 with built-in cooling channels.
[0040] The top of the vortex pump housing 603 and the bottom of the plunger pump housing 706 are fixedly connected.
[0041] The vortex pump housing 603 has a vortex pump inlet 6031 on its side, and the fixed plate 602 with built-in cooling channel has three fixed plate inlets 6023, one fixed plate cooling channel inlet 6021, and one fixed plate cooling channel outlet 6022 on its side. The fixed plate 602 with built-in cooling channel has a vortex pump outlet 6024 with a one-way valve at the bottom center.
[0042] The compression chamber 705 with built-in cooling channel has a compression chamber cooling channel inlet 7051, a compression chamber cooling channel outlet 7052, and a plunger pump inlet 7053 with a one-way valve on its side.

[0044] The Mars atmospheric filtration system 2 is connected to the vortex pump inlet 6031 via the piping system 1, allowing airflow to flow to the three fixed plate inlets 6023. The vortex pump outlet 6024 with a one-way valve is connected to the low-pressure storage tank 4 via the piping system 1. The low-pressure storage tank 4 is connected to the plunger pump inlet 7053 with a one-way valve via the piping system 1 through the plunger pump housing 706. The plunger pump outlet 7054 with a one-way valve is connected to the high-pressure storage tank 5 via the piping system 1 through the plunger pump housing 706.

The fixed plate cooling channel outlet 6022 is connected to the compression chamber cooling channel inlet 7051 via the piping system 1 through the vortex pump housing 603 and the plunger pump housing 706. The compression chamber cooling channel outlet 7052 is connected to the high-pressure storage tank 5 via the piping system 1 through the plunger pump housing 706 and the vacuum radiator 3.
[0045] A method for capturing and compressing the Martian surface atmosphere includes the following steps:
[0046] S1: Low-pressure compression step, disconnect the clutch, shut off the two vacuum radiators 3, start the dual-head motor 605, run the scroll compressor 6 alone, so that the Martian atmosphere is compressed into the low-pressure storage tank 4 by the scroll compressor 6 through the Martian atmosphere filtration system 2.
[0047] S2: High-pressure compression step, engage the clutch, and simultaneously run the scroll compressor 6 and the plunger compressor 7 to compress the gas in the low-pressure storage tank 4 into the high-pressure storage tank 5 by the plunger compressor 7.
[0048] S3: Continuous compression step. When the pressure in the high-pressure storage tank 5 reaches a certain level, the two vacuum radiators 3 are turned on to start the heat dissipation circuit. The gas in the high-pressure storage tank 5 flows through one vacuum radiator 3 into the fixed plate 601 of the built-in cooling channel and the compression chamber 705 of the built-in cooling channel, and then flows back to the high-pressure storage tank 5 through the other vacuum radiator 3. The speed of the dual-head motor 605 is increased to continuously capture and compress the Martian atmosphere and store it in the high-pressure storage tank 5.
[0049] During the continuous compression phase, the Mars atmospheric filtration system 2 filters dust from the Martian atmosphere and connects it to the vortex pump inlet 6031 via pipeline system 1. A dual-head motor 605 drives the moving disc 601 to move relative to the fixed disc 602 with its built-in cooling channel, compressing the Martian atmosphere and delivering it from pipeline system 1 to the low-pressure storage tank 4. The gas in the low-pressure storage tank 4 can be used for low-pressure jet cleaning and in-situ oxygen production. The gas in the low-pressure storage tank 4 is then delivered through pipeline system 1 to the plunger pump inlet 7053 with a one-way valve. After further compression, the gas is delivered through the plunger pump outlet 7054 with a one-way valve to the high-pressure storage tank 5 via pipeline system 1. The liquid or gas in this high-pressure storage tank can be used for supercritical carbon dioxide jet rock breaking. Another loop is drawn from the high-pressure storage tank 5 through the piping system 1, connected to a vacuum radiator 3 for heat dissipation, and then connected to the platen cooling channel inlet 6021 through the piping system 1. The flow from the platen cooling channel outlet 6022 is then connected to the compression chamber cooling channel inlet 7051 through the piping system 1, and the flow from the compression chamber cooling channel outlet 7052 is then connected to another vacuum radiator 3 through the piping system 1 for heat dissipation. Finally, the flow returns to the high-pressure storage tank 5 through the piping system 1 to dissipate heat for the scroll compressor 6 and the plunger compressor 7.
[0050] This invention employs a novel cooling technology that allows the cooling medium to flow through the high-temperature components inside the compressor. Compared to traditional scroll compressors and plunger compressors, this significantly improves heat dissipation efficiency, thereby ensuring the stability of the compressor at high speeds and effectively increasing the discharge capacity.
[0051] By adopting a series connection of scroll compressor and plunger compressor, the advantages of high capture speed of scroll compressor and high pressure ratio of plunger compressor are fully utilized. Compared with high-performance single compressor scheme, it is more efficient and easier to achieve high capture capacity and high compression ratio.
[0052] The device uses the high-pressure material it captures as a cooling medium. If a cooling pipe leaks, it can be repaired and the device can continue to be used, avoiding the loss of cooling medium that would render the device unusable. Compared to traditional coolant cooling methods, it does not require carrying a cooling medium, thus reducing the cost of transporting it to Mars.
[0053] The two types of compressors adopt an integrated design, using a single motor to drive both the scroll pump and the plunger pump simultaneously, which simplifies the system structure and effectively reduces the system size compared to simply connecting the two pumps through pipelines.
[0054] The above description is only used to further illustrate the technical content of the present invention so that readers can understand it more easily, but it does not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made in accordance with the present invention is protected by the present invention.
