密闭空间净化二氧化碳的实验研究

Experimental Study on the Carbon Dioxide Purification in Confined Space

研究了不同化学吸附剂在密闭空间去除二氧化碳的效果。结果表明,反应塔高径比对氢氧化钙、钠石灰吸附二氧化碳有较明显的影响,对氢氧化锂吸附二氧化碳影响不显著。三种吸附剂的最优吸附塔高为80mm,钠石灰去除二氧化碳的效果最好。

The removal efficiency of different carbon dioxide absorbents was studied by adopting the air purification technology. The results show that the height to diameter ratio visibly impacts on the carbon dioxide absorption efficiency for calcium hydroxide and sodium lime , while the impact is not significant for lithium hydroxide. The optimal adsorption tower is 80 mm high for three absorbents, the sodium lime has the best effect of removing the carbon dioxide.
