3) oxygen generating agent in self-rescuer of the present utility model is used KO
2with the mode that LiOH absorbent combines, can bring following effect:
1. at pure KO
2in oxygen generating agent tank, KO
2with CO
2the amount of oxygen generating with the reaction of steam is the twice left and right of wearer's oxygen demand, and unnecessary oxygen is given and discharged by air bleeding valve, and the utilization rate of oxygen is low, and adding of LiOH absorbent, makes the part CO in expiration
2react with LiOH, reduced KO
2the CO of reaction
2measure, improved the utilization rate of oxygen; Meanwhile, the LiOH absorbent of same volume is than the KO of same volume
2the CO that oxygen generating agent absorbs
2many, add after LiOH, can be that chemical pot for generating oxygen volume reduces.
2. produce heat few, KO
2with the reaction equation of the raw oxygen process of LiOH mixing oxygen generating agent be:
2KO
2+ 2H
2o → 4KOH+3O
2+ 3.4 kilocalories
2KOH+CO
2→ K2CO2+H
2o+45.2 kilocalorie
CO
2+ 2LiOH=Li
2cO
3+ H2O+32.32 kilocalorie
From above-mentioned two reaction equations, can find out KO
2the CO of the every absorption a part of oxygen generating agent
2the heat that heat release is 48.6 kilocalories, and the CO of the every absorption a part of LiOH absorbent
232.32 kilocalories of heats of heat release, like this as consumed the CO of same molecular amount
2, because of adding of LiOH absorbent, can reduce the reaction heat discharging in oxygenic reaction process.Thereby chemical pot for generating oxygen temperature reduces, this can prevent that oxygen generating agent is in the reaction later stage on the one hand, because temperature raises, occurs fusing, and the phenomenon that caking increases respiratory resistance, has also reduced suction temperature on the other hand.
