In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention. The technical characteristics in the embodiments of the present invention can be combined correspondingly without mutual conflict.
In the description of the present invention, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected to the other element, i.e., intervening elements may be present. In contrast, when an element is referred to as being "directly connected to" another element, there are no intervening elements present.
In the description of the present invention, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
In a preferred embodiment of the present invention, as shown in fig. 1, a system for capturing and converting carbon dioxide on a surface of a mars is provided, which comprises a mars atmosphere pipeline 1, a low-temperature stop valve 2, a filter 3, a low-temperature fan 4, a rotary wheel adsorber 5, a rotary wheel adsorption channel 6, a rotary wheel desorption channel 7, a sealing cover 8, a regeneration gas pipeline 9, a constant pressure valve 10, a condenser 11, a water collector 12, a compressor 13, a mixer 14, a mixed gas pipeline 15, an electric heater 16, a Sabatier reactor 17, a loop heat pipe 18, a loop heat pipe evaporation section 19, a loop heat pipe insulation section 20, a loop heat pipe condensation section 21, and a power line 22.
Wherein the rotary wheel absorber 5 is an adsorption and desorption device with an adsorbent arranged on the rotary wheel. The rotating wheel can be designed into a honeycomb wheel form to increase the specific surface area of the rotating wheel. The flow channel of the runner adsorber 5 comprises a runner adsorption channel 6 and a runner desorption channel 7, wherein most of the runner is positioned in the runner adsorption channel 6, and the other part of the runner is positioned in the runner desorption channel 7. The rotating wheel absorber 5 makes the rotating wheel absorbing water and carbon dioxide gas rotate back and forth between the rotating wheel absorbing channel 6 and the rotating wheel desorbing channel 7 through continuous rotation, so that the absorption and desorption regeneration are carried out synchronously. During actual work, after the gas enters the rotating wheel, the gas is discharged into the atmosphere after being adsorbed with the target component by the adsorbent in the rotating wheel adsorption channel 6, and when the rotating wheel part adsorbed with the target component rotates back to the rotating wheel desorption channel 7, the adsorbed target component can be desorbed from the rotating wheel again in a heating mode, so that the enrichment of the target component is realized. In order to ensure that the target components analyzed in the rotating wheel desorption passage 7 can be collected, a sealing cover 8 used for isolating the external atmosphere from the rotating wheel desorption passage 7 is arranged on the outer side of the rotating wheel desorption passage 7, and the desorbed target components enter the sealing cover 8 to prevent the external Mars atmosphere from influencing the purity of the desorbed gas of the rotating wheel adsorber. In the invention, the target component adsorbed by the rotating wheel is carbon dioxide in Mars atmosphere, but part of water is generally adsorbed at the same time, so that the adsorbing material filled in the rotating wheel can be selected from silica gel, zeolite 13X and other adsorbents to increase the adsorption capacity of the carbon dioxide.
The Sabatier reactor 17 is a reactor for reacting Sabatier reaction using Sabatier. The specific structure of the reactor is not limited, and the reactor can be realized by any reactor in the prior art. The Sabatier reaction is a non-exothermic reaction. Generally, in order to avoid the adverse effect of the low temperature of the Mars atmosphere on the Sabatier reaction, the Sabatier reactor 17 can be coated with an insulating material, and the internal reaction cavity is filled with a catalyst, wherein the catalyst can be an existing catalyst capable of catalyzing the Sabatier reaction.
In addition, in order to analyze the carbon dioxide and water adsorbed on the rotor in the rotor desorption passage 7, it is necessary to input heat to the rotor desorption passage 7. In the present invention, since the Sabatier reactor 17 generates heat, which in turn is detrimental to the conversion efficiency of the Sabatier reaction, heat from the Sabatier reactor 17 can be transferred to the rotating wheel desorption passage 7 by providing a heat pipe. The present invention may be provided with a loop heat pipe 18 for connecting the Sabatier reactor 17 to the wheel desorption passage 7. The loop heat pipe 18 is formed by connecting a loop heat pipe evaporation section 19, a loop heat pipe insulation section 20 and a loop heat pipe condensation section 21, and the principle of the heat pipe can be referred to in the prior art, which is not described in detail.
In addition, the invention also utilizes the low-temperature characteristic of the spark atmosphere to design the condenser 11 to cool the carbon dioxide and the water vapor, thereby separating the water and the carbon dioxide. The condenser 11 has a first passage and a second passage for heat exchange, the first passage flows through the mixed gas of carbon dioxide and water vapor desorbed by the rotary adsorber 5, and the second passage flows through the spark atmosphere. The average temperature of the atmosphere of the mars is about 216K, and the temperature can be used as a cold source to cool the mixed gas of the carbon dioxide and the water vapor, so that the water vapor is condensed into liquid drops to be separated from the mixed gas conveniently. In the present invention, the condenser 11 may be a finned tube heat exchanger.
The entry end direct exposure of mars atmosphere pipeline 1 is in the mars atmosphere for let in the mars atmosphere, and mars atmosphere pipeline 1 communicates low temperature stop valve 2, filter 3, low temperature fan 4 and runner adsorber 5's runner absorption passageway 6 back exit end evacuation in proper order, thereby makes the water and the carbon dioxide gas in the mars atmosphere that let in mars atmosphere pipeline 1 adsorb the entrapment by the adsorbent on the runner in runner absorption passageway 6.
In the invention, the filter 3 is used for removing dust in the Mars atmosphere, and can adopt filtering dust removal equipment, cyclone dust removal equipment or electrostatic dust removal equipment. In consideration of the reliability and efficiency of dust removal, the filter 3 preferably removes dust from the raw material gas by electrostatic dust removal.
In the present invention, the low temperature fan 4 is used to provide power for the input of Mars atmosphere. The day and night temperature difference of the Mars atmosphere is as high as 80K, the temperature change range in summer is about 185K-244K, the temperature change range in winter is about 172K-252K, and the temperature in most time periods is lower than the low-temperature starting limit of a common fan, so that a low-temperature fan type capable of resisting the Mars atmosphere temperature is required to be adopted.
The inlet end of the regenerated gas pipeline 9 is communicated with a sealing cover 8 outside the runner desorption channel 7, the pipeline is sequentially communicated with a constant pressure valve 10, a first passage of a condenser 11, a water collector 12 and the rear outlet end of a compressor 13 and is connected into a mixer 14, and a second passage of the condenser 11 flows through Mars atmosphere for cooling the first passage, so that carbon dioxide and water vapor adsorbed by the runner adsorber 5 are desorbed, separated and pressurized and then are introduced into the mixer 14 in a pure carbon dioxide form.
