The combustible gas pressure vessel further comprises an implosion backfire controller which has at least one one-way valve, wherein the one-way valve is arranged on the side walls or the two ends of the vessel body of the combustible gas pressure vessel; and the direction of the one-way valve is set so that when the implosion and backfire of the combustible gas pressure vessel occur, the surrounding air is allowed to pass through the one-way valve and enter inside the vessel body of the combustible gas pressure vessel, but the combustible gas inside the vessel body of the combustible gas pressure vessel is not allowed to pass through the one-way valve for escape.
Description
Technical field
Generally, the present invention relates to a kind of combustible gas pressure container.More particularly, the present invention relates to a kind of combustible gas pressure container with explosion-shrinkage fire control system device.
Background technique
In design, manufacturing and the using process of pressurized container, the Security of pressurized container is an aspect of can not ignore.Specifically for combustible gas pressure container, its Security is a primary aspect especially.
Day by day frequently various along with human being's production and life activity, increasing to the demand of the energy.Yet thing followed phenomenon but is the exhaustion day by day of the fossil energy sources of for example coal, oil, rock gas etc.And the negative effect that the production of fossil energy sources and use cause environment also more and more causes to be paid close attention to and anxiety widely.The good news is, accelerate exploitation and use the non-fossil energy sources of cleaning to become current knowledgeable people's common recognition already." hydrogen fuel " energy is because its preparation and store relatively easily and stable, and the use field is extensive relatively, thereby the degree of depth of its industrial applications and range are led over clean energy resourcies such as wind energy, solar energy in some sense.
At present cause a big factors of restriction to be to promoting the use of of hydrogen fuel energy sources: the safety issue of hydrogen fuel energy sources is solved as yet at all.The general existing way of hydrogen fuel energy sources is the hydrogen that is contained in the pressurized container, or is contained in hydrogen and oxygen mixed gas (hereinafter referred to as hydrogen and oxygen mixture) in the pressurized container.The use of hydrogen fuel energy sources generally is that hydrogen or the hydrogen and oxygen mixture that will be contained in the pressurized container burn by catheter directed firing unit, and then the heat energy that burning obtains directly utilized, perhaps the heat energy that again burning is obtained carry out corresponding conversion and the energy that obtains other types such as mechanical energy to be used for various uses.
Similar with the burning that is contained in other combustible fuel gas in the pressurized container, the burning of hydrogen fuel energy sources also is subjected to the puzzlement of tempering problem.Here said " tempering " is meant when the underpressure of the combustible fuel gas in the pressurized container that is contained in combustible fuel gas or the underpressure in the conduit between this pressurized container and the firing unit, flame on the firing unit causes the blast of danger even pressurized container along reverse importing conduit or even pressurized container.The tempering of hydrogen fuel energy sources is more more dangerous than the tempering of other combustible fuel gas, this be because since the inflammable and explosive characteristic of hydrogen with and the severity of blast, the tempering of hydrogen fuel energy sources generally all can lead to the heavy losses of heavy explosion and various resource (even comprise people life).
In view of the foregoing, in the prior art, the combustion gas utilized device uses long as far as possible gas conduct pipe (for example, at least 30 meters) usually, thereby interrupts tempering by the method for bending gas conduct pipe when finding tempering.
In the hydrogen fuel energy sources utilized device, the also additional anti-locking apparatus of tempering that uses a kind of " back-fire preventer " by name, this back-fire preventer is generally positioned near hydrogen fuel energy sources pressure vessel outlet place, is connected with conduit.Thereby in case tempering takes place, back fire flame was suppressed by this back-fire preventer before will entering pressurized container and extinguishes, thereby protection pressurized container and equipment make it to avoid blast.
Yet the above-mentioned long as far as possible gas conduct pipe and the use of back-fire preventer can not guarantee absolutely effective.In case its inefficacy, will lead to the blast and the loss, thereby and this be unacceptable also be unallowed.
In addition, the inventor has also found the characteristic a kind of rarely known by the people of hydrogen fuel energy sources pressurized container: " quick-fried contracting " characteristic.
The performance of " quick-fried the contracting " of hydrogen fuel energy sources pressurized container is: when the burner generation tempering supplied with by hydrogen fuel energy sources (especially hydrogen and oxygen mixture) pressurized container, moment can be taken place and sharply be descended in the pressure in this hydrogen fuel energy sources pressurized container.
Because tempering causes the pressure moment in the hydrogen fuel energy sources pressurized container sharply to descend, the speed that certainly will cause its back fire flame to be inhaled in the pressurized container is more faster than the speed that the back fire flame of general fuel is inhaled into, even thereby having adopted above-mentioned two kinds of preventive measure, hydrogen fuel energy sources (especially hydrogen and oxygen mixture) pressurized container also almost is difficult to blast after tempering takes place with avoiding.
Characteristic is present in the pressurized container of hydrogen fuel energy sources highlightedly though the inventor finds above-mentioned " quick-fried contracting ", yet can not infer therefrom for other inflammable gas energy and never have this phenomenon.
Summary of the invention
Because the puzzlement in the above-mentioned prior art field, the inventor reduces to contract because of tempering the is quick-fried possibility of blasting of the pressurized container of combustible fuel gas (especially hydrogen fuel energy sources) minimum even gets rid of as its target of trying hard to reach or even mission.
For realizing above-mentioned target, the inventor provides a kind of combustible gas pressure container at this, the tank body that described combustible gas pressure container has, this tank body is provided with air inlet pipeline that links to each other with the source of the gas of upstream and the supply air line that links to each other with the burner in downstream, wherein: described combustible gas pressure container also has explosion-shrinkage fire control system device, described explosion-shrinkage fire control system device is at least one one-way valve, described one-way valve is installed on the side or the two ends of the tank body of described combustible gas pressure container, the direction of described one-way valve is arranged to: described one-way valve allows surrounding atmosphere to enter the inside of the tank body of described combustible gas pressure container when described combustible gas pressure container generation explosion-shrinkage fire, but the inflammable gas of tank interior of forbidding described combustible gas pressure container from described one-way valve by overflowing.
Because when described combustible gas pressure container generation explosion-shrinkage is fiery, described one-way valve allows surrounding atmosphere to enter the inside of the tank body of described combustible gas pressure container by described one-way valve, therefore, the tank interior of described combustible gas pressure container is because " quick-fried the contracting " that tempering caused---that is the rapid decline of instantaneous pressure is inhibited in time, thereby back fire flame can not be inhaled into described combustible gas pressure container owing to instantaneous negative pressure occurring, thereby described combustible gas pressure container is avoided the danger of exploding.
The inventor also can comprise following optional feature at the flameproof apparatus that is used for combustible gas pressure container that this provides.
