对煤矿井下移动救生舱用LH型CO_2吸收剂的性能进行了研究。结果表明:LH型CO2吸收剂含水率≤0.50%,粉尘率≤2.0%,粒度范围在2mm～6mm占97.8%,吸收容量均值为0.82g/g,在低浓度CO_2的环境中,吸收速率仍然非常快;在10人型救生舱中,LH型吸收剂CO_2处理能力试验效果良好,能在持续通入5L/min CO_2的条件下,使初始浓度为1.00%的CO2在11 min内迅速下降至0.20%;救生舱真人试验96h,维持舱内CO_2气体的浓度在1%以下仅需LH型吸收剂16盒。
The performance of LH CO_2 absorber for mobile rescue capsule in coal mine was studied. The results showed that the LH type CO2 absorbent had a moisture content of ≤0.50%, a dusting rate of ≤2.0%, a particle size of 2mm ~ 6mm, accounting for 97.8% and an average absorption capacity of 0.82g / g. In low CO_2 environment, the absorption rate Very fast. In the 10-manned rescue capsule, LH-type absorbent CO 2 processing ability test results are good, with continuous introduction of 5L / min CO_2 conditions, the initial concentration of 1.00% of the CO2 in 11 min rapidly decreased to 0.20%; life-saving tank live test 96h, to maintain the concentration of CO 2 gas in the cabin below 1% only LH-type absorbent 16 boxes.
