Life support system for closed cabin

Abstract

The invention relates to a life support system for a closed cabin. The life support system comprises an air purification device 1, an oxygen storage device 2, an oxygen source device 3, a waste gas collecting device 4 and a pressure bearing pipeline 5. The air purification device 1 comprises a primary-effect filter net 6, an efficient filtering device 7, a storage battery 8, a nitrogen-oxygen separation device 9, a draught fan 10, a hand shaking draught fan device 11, a photocatalysis module 12, an electrostatic adsorption module 13, an oxygen generating module 14, a negative ion generator module 15, an intelligent operation module 16, an air inlet 17 and an air outlet 18. The system is a self-circulation system and can monitor the index of indoor air in the absolutely-closed environment and automatically conduct purification and conversion according to the set index, and it is ensured that the healthy breathing environment can still be continuously created for 72 or more hours under the situation of outage.

Description

technical field [0001] The invention relates to the technical field of health protection and life support in an airtight cabin, in particular to a life support system in an airtight cabin. Background technique [0002] As we all know, when people work in closed cabins, such as space capsules, submarines and other closed environments, a large amount of CO is emitted by breathing. 2 , NH 3 , SO 2 As well as hundreds of toxic and harmful waste gases containing organic substances, if they are not treated in a timely and effective manner, they will affect the health of the staff in the cabin, and even endanger their lives in severe cases. It can be seen that the air quality in the airtight cabin has become particularly important. It is necessary to ensure sufficient oxygen content and clean and pollution-free. At the same time, it is necessary to remove everyone's normal metabolites and bad odors. [0003] Most of the exhaust gas treatment devices or methods in various airtigh...

AI Technical Summary

Problems solved by technology

[0006] The above invention patents cannot process all the exhaust gas at one time, and there is still a risk of secondary pollution. The lack of a solution to provide pure oxygen cannot ensure that a healthy breathing environment can still be created in the event of a power outage.
