Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, real with concrete below in conjunction with the accompanying drawings
The present invention is further detailed explanation to execute mode.
As depicted in figs. 1 and 2, the preferred embodiments of the present invention provide a kind of passive dehydrogenation unit, described passive
Dehydrogenation unit includes housing 3, and the hydrogen module 2 that disappears；Wherein, hydrogen module 2 layered arrangement is disappeared described in inside described housing 3.Should
Device is used for eliminating combustible gas such as hydrogen and exceedes the rich air of hydrogen explosion lower limit (such as content more than 10%), and can prevent
Hydrogen fires.
Preferably, the hydrogen module 2 that disappears described in is made up of some hydrogen unit 1 that disappear being arranged in parallel at a distance of certain pitch space.Should
The hydrogen unit 1 component pattern that disappears can be not only used for the passive passive hydrogen that disappears, it may also be used for disappearing hydrogen by dynamic formula of active high throughput.
Preferably, hydrogen unit 1 is disappeared described in for lamellar.
Preferably, hydrogen unit 1 is disappeared described in for box-like.
Preferably, described in the disappear quantity of hydrogen module 2 be three layers, disappear hydrogen mould including the ground floor set gradually from the bottom up
Group, the second layer disappears hydrogen module and third layer disappears hydrogen module.Ground floor disappears hydrogen module for being entered by fuel gas higher for concentration
Row is preliminary to be eliminated, and disappears the combustable gas concentration in hydrogen module being lowered into the second layer, after the second layer disappears hydrogen module, flammable
Gas concentration reduces further, hence into third layer assembly module, reduces combustable gas concentration in this way and prevents blast
Occur.Certainly, the quantity of the hydrogen module that disappears can be other multilamellar, such as, include two-layer or four layers, can be according to actual
Need to arrange the concrete number of plies.
Preferably, the spacing that hydrogen unit is more than 20mm that disappears that described ground floor disappears in hydrogen module is arranged and subsidiary heat radiation
Fin structure.The ground floor hydrogen module that disappears contacts with high concentration fuel gas at first, eliminates the fuel gas such as hydrogen that concentration is higher
Time reaction heat maximum, temperature rise is the highest, uses big spacing to arrange the elimination unit of (more than 20mm) and subsidiary radiation fin structure,
For reaction heat quickly passes to eliminate the air between unit, reduction eliminates cell surface temperature, accelerates the right of air simultaneously
Stream heat exchange efficiency, improves the air mass flow that Natural Circulation is passed through, containing hydrogen and the carbon monoxide etc. that there is a need to elimination in this air
Combustible component.
Preferably, described in disappear hydrogen unit 1 built with the spherical or bar shaped beaded catalyst that active component is platinum or palladium,
Grain equivalent diameter is 1-6mm, and carrier is aluminium sesquioxide or molecular sieve.
Preferably, the hydrogen unit 1 that disappears described in is spaced on shelf 0～20mm parallel, that be vertically placed in described housing.Thus
Keeping top and the bottom clear air, air can be flowed by the backlash freedom between unit member.For the dehydrogenation unit of self-starting,
Mixed gas containing certain hydrogen concentration under the thermally-induced natural air stream of oxyhydrogen reaction attracts, natural flow from bottom to top.
Preferably, described housing 3 is the box-like cube of hollow, gas pass through from the bottom up described in disappear hydrogen module.
Preferably, described gas is fuel gas.
Meet the passive dehydrogenation unit of the preferred embodiment of the present invention, can be used for hydrogen content exceeding more than more than 10%
The air of hydrogen explosion lower limit, the safety that can be directly used for high concentration hydrogen eliminates, and releases high concentration hydrogen and reveals the combustion caused
Quick-fried accident.Under nuclear power station beyond design basis accident, the safety of the high concentration hydrogen in containment eliminates, and does not cause hydrogen quick-fried
Fried.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment, identical similar portion sees mutually.For system disclosed in embodiment
For, owing to corresponding to the method disclosed in Example, so describe is fairly simple, relevant part sees method part explanation
?.
Those skilled in the art can use different methods to realize described function to each specifically should being used for, but
It is this realization it is not considered that beyond the scope of this invention.
Obviously, those skilled in the art can carry out various change and the modification spirit without deviating from the present invention to invention
