为了深入研究钠石灰动态吸附CO2的规律特性，更好地将钠石灰用于地下工程空气环境保障工程实践，进行了钠石灰动态吸附 CO2的测试实验，测得了钠石灰的最大吸附效率，通过控制不同的环境参数来探究环境因素对于钠石灰动态吸附 CO2效率和吸附速率的影响，实验选取了温度和相对湿度两个变量因素，设置了4组不同的环境参数。通过实验可得出结论：相对湿度和温度对于钠石灰动态吸附 CO2的效率和速率都有影响，并且呈正相关，其中相对湿度的影响要强于温度，在等温不等湿时的最大动态吸附效率差达到6%，最大平均吸附速率差达281 mL/min；钠石灰对CO2的动态吸附稳定，不易出现解吸附，适合用于地下工程中消除CO2。

This paper conducted an experiment on dynamic absorption of carbon dioxide by sodium lime. The effects of environment factors and absorption rate on the absorption efficiency were investigated by controlling different environment parameters. Temperature and relative humidity were chosen as the controlling factors. The results showed that the maximum absorption efficiency of sodium lime;both relative humidity and temperature had influences on absorption efficiency and absorption rate,which were positively correlated;the effects of relative humidity were more obvious;the maximum difference in absorption efficiency was 6% and average dynamic absorption rate difference was 281 mL/min at different humidifies. The absorption process demonstrated stability and could be,suitable for carbon dioxide removal in underground applications.
