Accompanying drawing explanation
Fig. 1 is shown as nitrogen, the carbon dioxide comparative result to explosion velocity experiment value.
Detailed description of the invention
Embodiment 1:
The feature fired according to imflammable gas, the hydrogeneous therapeutic gas that the following three class proportioning compound modes preparations of employing can be used safely:
1, according to the limit that fires of hydrogen:
Hydrogen and the mixed limit that fires of air are 4%～75%(hydrogen volume concentration), the fire limit mixed with pure oxygen is 4%～95%, and when hydrogen volume concentration is firing beyond ultimate value, even if running into burning things which may cause a fire disaster, also will not explode.
Therefore,The proportioning compound mode of hydrogeneous therapeutic gas can be: hydrogen and the mixed volume concentration range of air are at 0-4% or 75-100%；Hydrogen and the mixed volume concentration range of pure oxygen are at 0-4% or 95-100%.
2, fire-retardant gas is mixed:
Research finds, the branched chain explosion of the combustible gas mixture such as hydrogen is reacted and has certain flame-proof explosion-proof effect by the gas such as nitrogen, carbon dioxide.Fire retardant mechanism mainly includes physical effect and chemical effect.Physics is fire-retardant is by dilute hydrogen gas mixture, reduces its concentration so that chemical reaction carries out very slow, and the energy released in the unit interval is not enough to support the propagation of forward position shock wave.Chemical flame retardant refers to that the fire-retardant gas added, under the high-temperature and high-pressure conditions that oxyhydrogen combustion blast produces, with intermediate product or the secondary response of product of oxyhydrogen reaction, by occupying active group, plays the effect of suppression chain explosion reaction development.Nitrogen is by physics fire retarding effect to the fire retardation of the hydrogen and oxygen gas mixture blast overwhelming majority, and their own is not involved in the chemical reaction of hydrogen detonation.The most both having there is physics fire retarding effect in carbon dioxide, there is again chemical flame retardant effect.It is therefore possible to use fire-retardant gas replaces oxygen or reduces oxygen concentration, thus reach the purpose of safe handling.Concrete mixed gases matching mode needs to be determined by experiment.
The flame-proof explosion-proof of hydrogen and oxygen gas mixture is tested by gas with various:
Experimental system is made up of parts such as shock tube, effect synchronous ignition device, gas mixer and measurement systems.Shock tube one end is sealed, and the other end is filled in row equipped with spark ignition and detonated.Tube wall is distributed the pressure change procedure after the igniting of pressure transducer record mixed gas.The hydrogen-oxygen mixed proportion of hydrogen and oxygen gas mixture is mol ratio 2:1, and the N selecting volume fraction to be 0,10%, 20%, 30%, 40%, 50%, 60%, 70% and 80%2Or CO2For fire-retardant gas, mixed gas initial pressure is 0.1Mpa, and initial temperature is room temperature.
Experimental result is as shown in Figure 1: there is a flex point near nitrogen content 60%, when nitrogen gas concn is more than 60%, rate of pressure decay is substantially accelerated, and nitrogen gas concn within 60% time, decline of pressure is relatively slower, points out us to use the nitrogen of more than 60% to mix with oxyhydrogen ternary and can effectively prevent hydrogen explosion.And near carbon dioxide content 50%, there is a flex point, point out us to use the carbon dioxide of more than 50% to mix with oxyhydrogen ternary and can effectively prevent hydrogen explosion.Hydrogen-oxygen mixed proportion is to be the ratio that explosive reaction the most easily occurs during mol ratio 2: 1, if using nitrogen-hydrogen or carbon dioxide-hydrogen two end number mixing, then nitrogen content necessarily will not explode more than 50% with carbon dioxide more than 60%.Therefore,The proportioning compound mode of hydrogeneous therapeutic gas can be: hydrogen and the mixed volume concentration range of nitrogen are at 0-40%；Volume concentration range after hydrogen and carbon dioxide mix is at 0-50%.
3, mixed inert gas:
Research shows, the branched chain explosion of the combustible gas mixture such as hydrogen is reacted and has certain flame-proof explosion-proof effect equally by the noble gas such as helium, argon, and fire retardant mechanism is mainly physics fire retarding effect.Owing to noble gas is difficult to carry out chemical reaction, only there is physics fire retarding effect, so the effect of flame-proof explosion-proof is equal to nitrogen.Therefore,The proportioning compound mode of hydrogeneous therapeutic gas can be: hydrogen and helium or the mixed volume concentration range of argon are at 0-40%.
The proportioning compound mode of hydrogeneous therapeutic gas provided above is the safest proportioning combination optimized.
Mixed gas can store under the conditions of 0.1-100Mpa.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
