Embodiment
The oxygen supply mechanism of self-aid high-concentration oxygen respirator is to utilize catalyst with coming out in conjunction with oxygen evolution in the peroxide aqueous solution, and its structure is divided into oxygen supply, storage oxygen bag, three minor structures of nose cup cover, and each minor structure device and the function that operation took place below are described.
1, oxygen supply: be the device (as shown in Figure 1) that oxygen takes place, its structure is to include peroxide aqueous solution soft plastic bag 2 and take up 7 two main bodys of deoxygenation soft plastic bag in oxygen supply 1, and check valve 4 and 3 two devices of plastics fold suction nozzle are arranged on oxygen supply shell 1.Taken up hydrogen peroxide 9 in the peroxide aqueous solution soft plastic bag 2, seen through peroxide aqueous solution suction pipe 5 and be connected to check valve 4 and plastics fold suction nozzle 3, sent pipe 6 arrival through peroxide aqueous solution and take up deoxygenation soft plastic bag 7.And take up porous catalyst 8 of deoxygenation soft plastic bag 7 intermediate package, and the oxygen 10 that reaction is produced is sent flexible pipe 12 through oxygen and is delivered in the storage oxygen bag 13, and deoxygenation residual solution 11 then is deposited in and takes up in the deoxygenation soft plastic bag 7.
The mode of operation of oxygen supply is: user presses down the back with plastics fold suction nozzle 3 and discharges, plastics fold suction nozzle 3 is because of the resilience that makes progress of its elasticity, simultaneously hydrogen peroxide 9 is taken out through peroxide aqueous solution suction pipe 5 and guided into, and check valve 4 restriction hydrogen peroxide 9 are back to peroxide aqueous solution soft plastic bag 2, but send pipe 6 arrival through peroxide aqueous solution and take up deoxygenation soft plastic bag 7, can contact porous catalyst (plating palladic zeolite) 8 and deoxygenation takes place this moment.The oxygen 10 that is produced is emersion upwards, sends flexible pipe 12 in storage oxygen bag 14 through oxygen; The deoxygenation residual solution 11 of hydrogen peroxide 9 through producing behind the deoxygenation then is deposited in and takes up among the deoxygenation soft plastic bag 7.Because the volume of compression molding material fold suction nozzle 3 one is fixing, thereby user presses down at every turn, and the amount of oxygen that the result obtains is also fixing.Repeatedly press down through user,, dwindle gradually, and deoxygenation residual solution 11 also makes more than becoming gradually and takes up deoxygenation soft plastic bag 7 volumes and become big gradually from peroxide aqueous solution soft plastic bag 2 volumes along with the extraction of peroxide aqueous solution 9.But both add cumulative volume and still reside within the oxygen supply shell 1 anxiety that nothing leaks.
2, storage oxygen bag: be the device that accumulates and filter oxygen.(as shown in Figure 1), its structure is to send into flexible pipe 14 and store up the storage oxygen bag 13 that oxygen bag oxygen is sent flexible pipe 18 with storage oxygen bag oxygen.Be divided under it liquid storage district 25 and on oxygen reservoir 17, therebetween and comprise that absorbent polymer fills bag 15 and 16 two parts of waterproof and breathable cloth.The design philosophy of storage oxygen bag is: through the oxygen of oxygen supply institute output, can contain the droplet of deoxygenation residual solution 11.For avoiding stimulating the respiratory tract of user, make oxygen do preliminary vapor-liquid separation through the liquid storage district 24 of storage oxygen bag 13 belows, and fill bag 15 desorptions by absorbent polymer deoxygenation residual solution 11 droplets that oxygen was mingled with are further removed, can send afterwards that flexible pipe 18 imports breathing masks or nasal tube is breathed use for sufferer via storage oxygen bag oxygen.The mode of operation of storage oxygen bag is: the oxygen that user is produced after plastics fold suction nozzle 3 is pressed down is sent into storage oxygen bag oxygen from oxygen supply and is sent into flexible pipe 14, at first enter the liquid storage district 24 of below, the deoxygenation residual solution 11 that it was mingled with is deposited in liquid storage district 24 and upwards fills bag 15 through absorbent polymer at this oxygen, the deoxygenation residual solution 11 that further will be mingled with removes.Thereafter oxygen is further determined deoxygenation residual solution 11 is removed, and is entered oxygen reservoir 17 more upwards through waterproof and breathable cloth 16, and the oxygen of this moment has had good quality, person's utilization to be used.User need be enclosed within the nape band 23 of storage oxygen bag 13 tops and makes the liquid storage district 24 of storage oxygen bag 13 fall in the below on the neck in use, so just can make 13 normal operations of storage oxygen bag.
3, nose cup cover: be to make things convenient for user to draw the device of oxygen.(as shown in Figure 1), its structure is that the mode person of being to use of its use is placed in the hindbrain Wood-scoop with a braces 22 with the combination of manifold 19, nose cup 20, cushion 21, a braces 22, and the breathing that sees through nose cup 20 natures gets final product.The function mode of nose cup cover is as follows: when oxygen reservoir 17 has been full of oxygen, be subjected to the influence of external atmospheric pressure, naturally can send flexible pipe 18 through storage oxygen bag oxygen and be pushed to nose cup 20 inside, air-breathing if user does not have at this moment, excess of oxygen can be thrown among the atmosphere through manifold 19.Oxygen deficiency if user is air-breathing in the oxygen reservoir 17, air also can feed nose cup 20 along manifold 19, can not allow user that the sensation of inspiratory dyspnea is arranged.When user was exhaled, carbon dioxide enriched expiration was discharged downwards through Non-return air valve 25 at the front end of nose cup 20, can not allow user that the sensation of expiratory dyspnea is arranged.
The making of aforementioned plating palladium zeolite catalyst is to have the noble metal of catalyst on the zeolite surface chemical plating.Below narrate production process:
1. at first select for use zeolite should minimumly meet following specification: 1) specific surface area 200m
2/ g, 2) particle diameter 3mm.
2. zeolite being cleaned the removal powder cuts.
3. immerse the pretreating reagent aqueous solution.
4. immerse catalyst noble metal aqueous solution, taking-up drains.
5. immersion becomes element state with Reducing agent reduction noble metal, and taking-up drains.
Inserting the anaerobic baking box dries with 120 ℃.
