摘　　要：为了防止封闭型工作环境空气中CO2的含量超标,应用低温液化的方法来分离空气中CO2。对采用级联式液化、氮膨胀液化降低空气中CO2浓度的流程进行了模拟计算和关键参数的比较,得出利用低温液化法从空气中分离出二氧化碳,达到净化空气、改善密闭空间空气品质的方案是可行的。The cryogenic liquefaction is applied to separate CO2 from the air, for the sake of preventing the transnormal CO2 composition of airproof air in the airtight working environment. The simulation of the cascade cycle and N2 Expander cycle reducing the CO2 composition of airproof air was done, as well as the key parameter comparison of the two processes. The result shows the cryogenic liquefaction project separates CO2 from the air is feasible, which can purify and improve the air character in the airtight room.
