- Abstract
CO2 removing technology is one of the key techniques for environment control and life support system in manned space station. Four-bed zeolite method is considered to be the most suitable used in space station by comparing with several other regenerative methods for removing CO2. In this paper, a device for this method is designed, mainly including two drying beds, two adsorption beds for CO2, one cooler for air/water heat exchanging, six directional control valves, two check valves and one fan. The maximum gas purification rate for this device can reach 4kg/d and the maximum gas loss is 80g/d. The partial pressure for CO2 is no more than 0.7kPa. Furthermore, the working principles of main components such drying bed, CO2 sorption and desorption system, recycle pump and various sensors are introduced in detail.
