Problems solved by technology

However, these solutions fail to efficiently couple the carbon dioxide enrichment process and the methanation process, which will inevitably reduce the energy consumption of the entire system, thereby increasing the system volume, weight and power consumption

Embodiment 1

[0046] In a space capsule with a crew of 5 people, if the volume of space in the cabin is 6m 3 , if left untreated, within one day CO 2 The concentration will reach more than 30%. For this purpose, a CO 2 enrichment and methanation reactor, in CO 2 CO enrichment and methanation reactor 2 The adsorption chamber is filled with solid ammonia adsorbent (SAWD), and a certain amount of methanation catalyst is filled in the methanation reaction chamber; according to the adsorption and CO 2 The cycle of the methanation reaction, set two CO 2 The enrichment and methanation reactors are carried out alternately, thereby ensuring the CO 2 The concentration is kept at a low level. First, blow the gas in the passenger compartment into CO through valve 7 2 Enrichment and Methanation Reactor 3, CO 2 The gas is enriched in the adsorption chamber and passes through the outlet CO 2 Concentration online analysis 14 detection, when CO 2 When the concentration exceeds the set value, valve...

Abstract

The invention relates to a CO2 enrichment and methanation process in a sealed space and a CO2 enrichment and methanation reactor. The CO2 enrichment and methanation process is mainly technically characterized in that the content of CO2 inside the sealed space can be effectively controlled and oxygen essential for survival can be provided. The CO2 enrichment and methanation reactor is compact in structure, CO2 enrichment and methanation reaction are integrated, and thus a CO2 desorption process used inside the sealed space is greatly simplified. By adopting the CO2 enrichment and methanation process and the CO2 enrichment and methanation reactor, CO2 inside the sealed space (in an underwater submarine and a space station) can be efficiently desorbed, and oxygen essential for survival is provided, so that the life and property security of human beings in working in space capsules or submarines is ensured.

Description

technical field [0001] The invention belongs to the field of catalytic reaction and system integration, in particular to a CO 2 Enrichment and methanation processes and reactors. technical background [0002] CO 2 The continuous accumulation and increase of the concentration in the gas will lead to the decline of the air quality of the system, which will cause certain harm to human health and life. Atmospheric CO 2 The concentration is 0.03%, when the CO in the atmosphere 2 When the concentration reaches 0.1%, people will feel nausea and discomfort; when it reaches 1%, it will cause fainting and fatigue; when it reaches 2%, breathing and heartbeat will speed up; when it reaches 3%, the central nervous system will be paralyzed; When it reaches 5%, human breathing can only last for 30 minutes; when it reaches above 10%, it will cause people to lose consciousness or even die; therefore, to reduce the CO in the closed system 2 The content is very important to maintain the n...
