The utility model patent is achieved through the following technical solutions:
A kind of new type mining isolation type chemical-oxygen self-rescuer of oxygen discharging speed equilibrium, it is under all immovable prerequisite of existing various mining isolation type chemical-oxygen self-rescuer basic structures, only packed for a kind of non-woven fabrics calcium hydroxide being mixed is put in the raw oxygen tablet of the potassium superoxide loaded in chemical pot for generating oxygen, wear the too fast shortcoming of use oxygen discharging speed in mid-term to improve such self-rescuer, make oxygen discharging speed balanced, steady; Its technical characteristic is: mix in the chemical pot for generating oxygen of the raw oxygen tablet of original only filling potassium superoxide and put the packed calcium hydroxide of appropriate non-woven fabrics; Because calcium hydroxide can absorb the CO2 in personnel's breath, also can steam in simultaneously stability personnel breath, this just makes potassium superoxide tablet oxygen discharging speed when putting oxygen mid-term balanced, steadily.
Described mining isolation type chemical-oxygen self-rescuer has guard time to be several form such as 30min, 60min, because its guard time is different, in its volume, weight and chemical pot for generating oxygen, the weight of the potassium superoxide tablet of filling is also just different, but their operation principle is all identical.
Described mining isolation type chemical-oxygen self-rescuer, when entering well staff emergency escape and wearing this type of self-rescuer, the steam that the potassium superoxide tablet of filling in this type of self-rescuer chemical pot for generating oxygen and emergency escape personnel mouth be interior breathes out and the chemical equation of carbon dioxide are:
2KO
2+ H
2o=2KOH+3/2O
2+ heat (1)
2KOH+CO
2=K
2cO
3+ H
2o+ heat (2)
As can be seen from above-mentioned reaction equation, potassium superoxide tablet combines with the steam of breathing out in personnel's mouth, really can produce oxygen to carry out staff and breathe, as long as be filled into enough potassium superoxide tablets chemical pot for generating oxygen is in-built, it just can provide enough oxygen staffs to escape danger escape.But, also can find out from above-mentioned reaction equation, in the process of potassium superoxide tablet and steam chemical combination, oxygenous while, also can produce KOH, and the CO breathed out in KOH and personnel's mouth
2combine, steam and K can be produced further again
2cO
3, this also just describes, and why gives birth to oxygen speed comparatively slowly when wearing and using this type of self-rescuer initial stage and later stage, and to giving birth to the reason of oxygen excessive velocities during mid-term.Because, during to mid-term, the steam of breathing out in personnel's mouth and CO
2roll up, just cause chemical reaction process and accelerate, a large amount of oxygen generates out fast.For isolation type chemical-oxygen self-rescuer wear use mid-term time oxygen discharging speed this physical feature too fast and phenomenon, take effective method and measure, stop steam and CO
2roll up, the shortcoming that oxygen discharging speed is too fast can be slowed down, thus make oxygen discharging speed steady, balanced.
The nonwoven fabrics package bag of the packed calcium hydroxide of described non-woven fabrics, what adopt is that the non-woven fabrics of nontoxic environment-friendly type processes, it has good permeability, and calcium hydroxide is encapsulated in this sack, is to be convenient to them to mix comparatively be equably put in potassium superoxide tablet.
The calcium hydroxide loaded in described non-woven bag, can C02 in efficient absorption personnel breath, also can absorb a certain amount of steam in personnel's breath simultaneously.
The calcium hydroxide loaded in described non-woven bag, its gross weight of isolation type chemical-oxygen self-rescuer test of many times taking guard time as 30min through us is about 60 grams, be divided in the non-woven bag of more than 5, for playing effect that they absorb steam, absorbing carbon dioxide, mix more equably in the potassium superoxide tablet being put into filling in chemical pot for generating oxygen, make to put that oxygen potassium superoxide in mid-term tablet is balanced, to put oxygen effect reposefully better.For the isolation type chemical-oxygen self-rescuer that other guard time is not identical, can mix in potassium superoxide tablet by experiment and put the packed calcium hydroxide of appropriate non-woven fabrics, can reach balanced equally, put oxygen effect reposefully.
The beneficial effects of the utility model are: packed for non-woven fabrics calcium hydroxide is mixed comparatively equably and is put in the potassium superoxide tablet of chemical pot for generating oxygen, isolation type chemical-oxygen self-rescuer is worn use to put mid-term oxygen amount equilibrium, steadily, eliminate such self-rescuer wear use mid-term put too fast, the too much shortcoming of oxygen amount, and then bring the series of advantages such as guard time prolongation, respiratory resistance minimizing, suction temperature reduction, make the isolation type chemical-oxygen self-rescuer manufacturing technology of China shorten the distance with international most advanced level.
