Abstract
The invention provides a distributed hydrogen eliminating device. The distributed hydrogen eliminating device comprises a fixed part and a catalysis hydrogen eliminating unit, wherein the catalysis hydrogen eliminating unit is detachably connected with the fixed part. Compared with the prior art, the distributed hydrogen eliminating device provided by the invention has the beneficial effects of being applicable to a narrow space and convenient and flexible in application.
Description
Technical field
The present invention relates to a kind of dehydrogenation unit, particularly relate to the dehydrogenation unit in a kind of nuclear power field.
Background technology
When nuclear power station design basis and beyond design basis accident, can produce a large amount of hydrogen in containment, hydrogen reaches one
Determine concentration, exceed LEL, may result in blast accident, threaten the safety of containment.Therefore, existing nuclear power station sets mostly
Put passive hydrogen recombiner, closed the hydrogen under the high temperature in space, high pressure, high humidity environment for containment and eliminate.
But, this usual volume of passive hydrogen recombiner is bigger, it is difficult to arranges in a conned space, thus causes this
A little spaces become the accumulation of dead angle area generation density of hydrogen, cause high concentration hydrogen detonation.It addition, this passive hydrogen recombiner
Use inconvenience, underaction, be difficult to remove need not and use when, thus occupy many spaces, to operator logical
Out-of-date, or bring inconvenience during maintenance.
Therefore, the dehydrogenation unit that one can be applicable to narrow space and flexible and convenient to use how is provided to become
Problem demanding prompt solution.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of distributed dehydrogenation unit, described distributed dehydrogenation unit bag
Include fixed part and catalytic hydrogen-eliminating unit, detachably connected between described catalytic hydrogen-eliminating unit and described fixed part.
Preferentially, described catalytic hydrogen-eliminating unit is board-like catalytic hydrogen-eliminating unit.
Preferentially, described catalytic hydrogen-eliminating unit is boxlike catalytic hydrogen-eliminating unit.
Preferentially, described catalytic hydrogen-eliminating unit is plugged in described fixed part.
Preferentially, described catalytic hydrogen-eliminating unit card is together in described fixed part.
Preferentially, described catalytic hydrogen-eliminating unit is parallel hangs on described fixed part.
Preferentially, at the shutter being provided above liquidproof spray of described catalytic hydrogen-eliminating unit.
Preferentially, during described distributed dehydrogenation unit is arranged at the narrow space needing to eliminate hydrogen.
Preferentially, the quantity of described distributed dehydrogenation unit is multiple, and combination is distributed across plant compartment in containment.
Preferentially, described fixed part is frame or body of wall.
Compared with prior art, the present invention has and is applicable to narrow space, the beneficial effect of easy to use and flexible.

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 present invention is preferable to carry out proposing a kind of distributed dehydrogenation unit, described distributed disappears
Hydrogen production device includes fixed part 3 and catalytic hydrogen-eliminating unit 1, detachably connected between catalytic hydrogen-eliminating unit 1 and fixed part 3.Due to
The volume of catalytic hydrogen-eliminating unit 1 is little, for small-sized dehydrogenation unit, therefore can be arranged on to plug and play narrow and small sky as required
Within between, except the hydrogen in this region.Meanwhile, it is detachably connected between catalytic hydrogen-eliminating unit 1 and fixed part 3, therefore, not
Catalytic hydrogen-eliminating unit 1 can be removed from fixed part 3 when of needs, will not take up space.This distributed dehydrogenation unit goes
Except external shell, broken the design concept of original dehydrogenation unit, can in little space randomly, differentiation arrange, make
Obtain dehydrogenation unit not in being confined to concrete equipment.
Preferentially, catalytic hydrogen-eliminating unit 1 is board-like catalytic hydrogen-eliminating unit.
Preferentially, catalytic hydrogen-eliminating unit 1 is boxlike catalytic hydrogen-eliminating unit.
Preferentially, catalytic hydrogen-eliminating unit 1 is plugged in fixed part 3.
Preferentially, catalytic hydrogen-eliminating unit 1 is sticked in fixed part 3.
Preferentially, catalytic hydrogen-eliminating unit 1 is parallel hangs on fixed part 3.
Preferentially, at the shutter 2 being provided above liquidproof spray of catalytic hydrogen-eliminating unit 1.Prevent liquid and catalysis
The catalyst in hydrogen unit 1 that disappears contacts thus causes this catalyst effect to reduce.
Preferentially, during described distributed dehydrogenation unit is arranged at the narrow space needing to eliminate hydrogen.In narrow space,
Owing to traditional dehydrogenation unit cannot be placed because volume is excessive, therefore, easily there is hydrogen, carbon monoxide in this space content
Accumulate Deng combustable gas concentration, cause high concentration hydrogen detonation.This distributed dehydrogenation unit is particularly suited for this narrow space.
Can be directly used for hydrogen in nuclear power station and be prone to the gas flow dead of accumulation.
Preferentially, the quantity of described distributed dehydrogenation unit is multiple, and combination is distributed across plant compartment in containment.
According to different installation regions space size, with selectivity, multiple distributed dehydrogenation units can be installed.For example, it is possible to by multiple distributions
Formula dehydrogenation unit is set to be arranged in parallel across a certain distance mutually.
Preferentially, fixed part 3 is frame or body of wall.This fixed part 3 can select neatly, as long as catalysis can be made to disappear
Hydrogen unit 1 is fixed.
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
