[0045] Example 1:

[0046] In a space capsule with 5 passengers, if the volume of the space in the passenger capsule is 6m 3 , If not processed, CO within one day 2 The concentration will reach more than 30%. To this end, design 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 adsorption and CO 2 The cycle of methanation reaction, set up two CO 2 The enrichment and methanation reactors alternate to ensure the CO in the crew compartment 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 va...

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...
