Abstract

The invention provides a chemical ignition device. The chemical ignition device comprises an accommodating part prepared by a wire mesh, wherein sealing elements are arranged at the upper and lower parts of the accommodating part respectively; the outer side of the accommodating part is wrapped by a membrane material used for preventing water vapor and air to penetrate; chemical substances which are inflammable when encountering water vapor are placed inside the accommodating part and inert gases are introduced in the accommodating part. Compared with the prior art, the chemical ignition device has the beneficial effects that the device can spontaneously ignite to remove hydrogen according to change of the external environment, without external energy input; the hydrogen risk can be still effectively relieved in case of power failure or emergency power fail.

Description

A kind of chemical formula igniter
Technical field
The present invention relates to the chemical formula igniter of a kind of chemical formula igniter, more particularly, to nuclear power field.
Background technology
Hydrogen lighter used by nuclear power station mostly is energy dynamic formula lighter at present, that is, need extra power to input, by persistently adding Heat makes heater element surface produce high temperature, lights hydrogen when temperature is sufficiently high, thus eliminating hydrogen.When appearance has a power failure or standby When using power-fail, this lighter will be unable to work.If now had an accident in nuclear power plant containment shell, then can dynamic formula igniting Device cannot eliminate hydrogen in time.
Therefore, how to provide one kind without extra power input, can be according to the temperature change spontaneous ignition of actual environment The igniter of hydrogen of carrying out disappearing becomes problem demanding prompt solution.
Content of the invention
The present invention is directed to the deficiencies in the prior art, proposes a kind of chemical formula igniter, described chemical formula igniter bag Include the receiving portion being made up of metal gauze, be respectively provided with sealing member in the upper and lower of described accommodation section, in described accommodation section Outside wrap up membrane material for preventing vapor and air permeable, place inside described accommodation section and meet the easy burning of vapor Learn material and be filled with noble gases.
Preferably, described sealing member is corrosion resistant plate.
Preferably, described chance the inflammable chemical substance of vapor be carbide or and potassium borohydride or and sodium borohydride.
Preferably, described noble gases be nitrogen or and helium or and argon.
Preferably, described accommodation section is cylindric.
Preferably, when ambient temperature reaches predetermined value, described membrane material is opened, and described chemical substance meets vapor Burning, hydrogen is lighted.
Preferably, described chemical formula igniter is applied to nuclear power field.
Preferably, described chemical substance is being completely cut off with vapor in home.
Compared with prior art, the present invention has and can spontaneously carry out igniting according to the change of external environment condition and disappear hydrogen, no Need the beneficial effect of extra power input, when occurring having a power failure or stand-by power supply lost efficacy, remain able to effectively alleviate hydrogen Risk.
Brief description
Fig. 1 is the schematic diagram of the chemical formula igniter meeting the preferred embodiment of the present invention.
1- chemical formula igniter;
2- metal gauze;
3- prevents the membrane material of vapor and air permeable;
4- meets the inflammable chemical substance of vapor.
Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically real The present invention is further detailed explanation to apply mode.
As shown in figure 1, the preferred embodiment of the present invention provides a kind of chemical formula igniter 1, described chemical formula igniting dress Put 1 receiving portion including being made up of metal gauze 2.Preferably, described accommodation section is cylindric, cube etc., can basis It is actually needed design.The gas transmissive metal gauze such as vapor and air 2.
It is respectively provided with sealing member in the upper and lower of described accommodation section it is preferable that described sealing member is corrosion resistant plate.
Wrap up the membrane material 3 for preventing vapor and air permeable in the outside of described accommodation section.In normal temperature model In enclosing, this membrane material is unaffected, can be effectively prevented vapor and air permeable enters the inside of receiving portion.
Place inside described accommodation section and meet the inflammable chemical substance of vapor 4 and be filled with noble gases.Chemical substance is not Can spill from metal gauze.Preferably, described chance the inflammable chemical substance of vapor be carbide or and potassium borohydride or and boron Sodium hydride.Preferably, described noble gases be nitrogen or and helium or and argon.
The operation principle of the chemical formula igniter 1 of the present invention is, after having an accident in nuclear power plant containment shell, to discharge hydrogen Gas and vapor, temperature raises, and when temperature exceedes predetermined value, membrane material 3 is opened, and in metal gauze 2, chemical substance 4 is met water and steamed Gas burns, and hydrogen is lighted, thus alleviating Hydrogen risk.After chemical substance burning or with gaseous product release, or form solid Product resides in metal gauze 2.
Preferably, described chemical formula igniter 1 is particularly suited for nuclear power field.
Preferably, described chemical substance is being completely cut off completely with vapor in home.
By the chemical formula igniter 1 of the preferred embodiment of the present invention, without extra power input.Ignition performance and environment Condition is relevant with therein chemistries.Institute is chance water using chemical substance 4 or vapor easily occurs combustion chemistry thing Matter, and adopt adequate measure, such as above-mentioned membrane material 3 so that this chemical substance 4 is completely cut off with vapor in home, Prevent from burning in home.After in nuclear power station, accident occurs, temperature raises, and vapor produces, chemical formula igniter 1 Automatically light, thus the hydrogen that ignites, alleviate Hydrogen risk.
In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment stressed is and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.For system disclosed in embodiment For, due to corresponding to the method disclosed in Example, so description is fairly simple, referring to method part illustration in place of correlation ?.
Those skilled in the art can use different methods to each specific application realize described function, 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 the various changes and modification spirit without deviating from the present invention to invention And scope.So, if these modifications of the present invention and modification belong to the claims in the present invention and its equivalent technologies scope it Interior, then the present invention is also intended to including these changes and modification.
