摘要
矿井救生舱是在矿井发生事故后为遇险人员提供临时保护措施和生命保障的密闭设备。在等待救援过程中，去除救生舱内的CO2是其空气净化的关键技术之一，而碱石灰具有毒性小、吸附稳定性高、使用方便和价格便宜等优点，适合作为救生舱空气净化的吸附剂。实验研究了救生舱在10 000×10-6和8 000×10-6的CO2浓度下，碱石灰在不同风速（0.5、1.0、1.5 m/s）对CO2的吸附性能，结果表明适当降低风速可提高碱石灰对CO2的吸附能力；CO2 浓度由8 000×10-6提高到10 000×10-6，碱石灰的吸附效率下降2%～4%；并根据设计条件计算得在矿井救生舱（室）采用空调净化一体机的条件下，在106 h的额定防护时间内至少需要储备157.9 4 kg碱石灰。
The mine rescue capsule is the equipment that provides interim measures and life support for underground survival in the mine accident. In the process of waiting for rescue, one of the key technologies of cabin air purification is to remove CO2 in the capsule. And compared with other adsorbent, the sodium lime has the advantages of lower toxicity, more stable performance, easy to use and cheap, which are suitable properties as an adsorbent used for cabin air purification. In the 10 000 ×10-6 and 8 000×10-6 concentrations of CO2, we test the adsorption performance of sodium lime in different fluid velocity（0.5 m/s, 1.0 m/s, 1.5 m/s）. The conclusion of this study shows that reducing the velocity of fluid can improve the sodium lime adsorption capacity of CO2; the adsorption efficiency of soda lime decreased from 2% to 4% while the concentration of CO2 increased from 8 000×10-6 to 10 000×10-6; and according to the calculation in the design conditions, mine rescue capsule needs to reserve at least 157.94 kg sodium lime in air conditioner ＆ purifier AIO in the 106 hours .
