Problems solved by technology

[0004] However, when the manned spacecraft conducts a long-distance long-distance flight, limited to launch conditions or economic considerations, it is impossible to launch a supply ship. The above short-term solutions cannot meet the requirements of manned spacecraft for the control of carbon dioxide concentration in airtight cabins during long-distance flight.

Abstract

The invention discloses a carbon dioxide concentration control system for a closed capsule of a manned spacecraft. The carbon dioxide concentration control system comprises a carbon dioxide extraction device, a carbon dioxide transmission channel, an electrolyzer and a power supply device, wherein the carbon dioxide extraction device is arranged in a gas flowing system of the closed capsule, one end of the carbon dioxide transmission channel is connected with the carbon dioxide extraction device, the electrolyzer is connected with the other end of the carbon dioxide transmission channel and is capable of solidifying carbon dioxide, and the power supply device is used for supplying electric power for the electrolyzer. In the carbon dioxide concentration control system disclosed by the invention, after carbon dioxide in the gas flowing system of the closed capsule is collected, the collected carbon dioxide is solidified into an organic matter through reduction reaction, so that carbon dioxide in the gas flowing system can be removed directly, and the concentration of carbon dioxide in the closed capsule is reduced further; therefore, the long-term control on carbon dioxide concentration can be realized.

Description

technical field [0001] The invention relates to the technical field of gas concentration control, in particular to a carbon dioxide concentration control system in a closed cabin of a manned spacecraft. Background technique [0002] To realize the long-distance interstellar travel of manned spacecraft, the treatment of the carbon dioxide produced by the metabolism of astronauts in the closed cabin is a problem that must be solved. The carbon dioxide concentration in the closed cabin must be controlled within the acceptable range of the human body, otherwise it will endanger the space flight personnel safety. [0003] When a manned spacecraft is operating in near-Earth space, the control of the concentration of carbon dioxide in the airtight cabin can adopt a short-term solution, by absorbing the carbon dioxide in the airtight cabin through the carbon dioxide adsorbent or absorbing the carbon dioxide in the airtight cabin through the carbon dioxide absorber, and then resupply...
