摘　　要：水下航行器长航时，如何改善舱室内大气环境，持续地提供呼吸的氧气一直困扰着人类。在分析了大量国内外技术的基础上，采用固态胺吸附解吸CO2技术、Sabatier还原CO2技术、固体聚合物水电解技术相互结合的环控生保系统，处理座舱内的CO2并制取一定数量的氧气。实验对CO2吸附、还原及电解制氧3个系统进行了设计。实验证明，所研制的环控生保系统满足所设计的人数需求，CO2脱吸发生在反应开始的5～8min，Sabatier反应器中主反应发生在前段，SPE电解系统稳定，并能将CO2浓度控制在0．2％以下，此系统能够满足水下航行器航行过程中人员对氧气和水的需求。When submarine navigates for long time, how to improve cabin＇ s atmosphere environment and continue providing oxygen and drinkable water always trouble humanity. On the base of analysis at a great deal of techniques, the environmental control and life support system（ECLSS） combining techniques of solid amine adsorption and desorption CO2 ,Sabatier deoxidize COg and solid polymer electrolyte electronalysis was used to dispose CO2 in cabin and obtain the preparation of oxygen and drinkable water. The experiment designed CO2 adsorption,reduction and SPE electrolysis systems. It was showed that the ECLSS could fulfill the designed needs of oxygen, CO2 desorption occurred at 5 -8 rain initial reaction, principal reaction in Sabatier reactor occurred in beginning, SPE electrolytic system was stable, the carbon dioxide concentration was controlled lower than 0.2%. The needs of oxygen and drinkable water for aircraft ocean-below could be met bv the designed system.
