为比较超氧化物药板和LiOH颗粒的二氧化碳吸收性能,通过密闭试验研究了在超氧化钾药板的使用条件下LiOH罐的二氧化碳吸收性能。试验证明,在药板的使用条件下,一罐LiOH颗粒(4.2kgLiOH)能够在30min内将自由空间为36m3的密闭空间内的二氧化碳浓度由2%降至1%,且在LiOH颗粒吸附饱和之前,一罐LiOH颗粒能够将密闭室内的二氧化碳浓度控制在1%以下。经计算可知,一个氢氧化锂罐的二氧化碳吸收能力为一箱药板(9.5±0.3kg药板)的1.44倍。
In order to compare the CO 2 absorption performance of superoxide anion (LiO) particles and LiOH particles, the CO 2 absorption capacity of LiOH cans under the conditions of use of superoxide medicine plates was studied by airtight test. It has been demonstrated that one can of LiOH pellets (4.2 kg LiOH) can reduce the concentration of carbon dioxide in a confined space with a free space of 36 m3 from 2% to 1% within 30 min under the conditions of use of the pellet, and before the LiOH pellet is saturated , A can of LiOH particles can control the indoor concentration of carbon dioxide in 1% or less. Calculations show that a lithium hydroxide tank has a carbon dioxide absorption capacity of 1.44 times that of a box of pills (9.5 ± 0.3 kg plate).
