Abstract
The utility model provides a kind of chemical formula igniter, the chemical formula igniter includes the receiving portion being made up of woven wire, in the upper and lower part of described accommodation section, seal is set respectively, wrapped up in the outside of described accommodation section for preventing the membrane material of vapor and air permeable, placed inside described accommodation section and meet the inflammable chemical substance of vapor and be filled with inert gas.Compared with prior art, the utility model has and igniting can be spontaneously carried out according to the change of external environment condition disappears hydrogen, the beneficial effect inputted without extra power, has a power failure in appearance or during stand-by power supply failure, remains able to effectively alleviate Hydrogen risk.
Description
Technical field
The utility model is related to a kind of chemical formula igniter, more particularly to nuclear power field chemical formula igniter.
Background technology
Hydrogen igniter used in current nuclear power station is generally energy dynamic formula igniter, that is, needs extra power to input, by persistently adding
Heat causes heater element surface to produce high temperature, hydrogen is lighted when temperature is sufficiently high, so as to eliminate hydrogen.When occurring having a power failure or standby
When using power-fail, the igniter will be unable to work.If now occurring accident in nuclear power plant containment shell, then can dynamic formula igniting
Device cannot eliminate hydrogen in time.
Therefore, how to provide a kind of without extra power input, can be according to the temperature change spontaneous ignition of actual environment
The igniter of hydrogen of disappear becomes urgent problem to be solved.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of chemical formula igniter, the chemical formula igniting dress
The receiving portion including being made up of woven wire is put, seal is set respectively in the upper and lower part of described accommodation section, is held described
Receive the outside in portion and wrap up for preventing the membrane material of vapor and air permeable, place that to meet vapor easy inside described accommodation section
Fire chemical substance and be filled with inert gas.
Preferably, the seal is stainless steel plate.
Preferably, the chance vapor inflammable chemical substance be calcium carbide or and potassium borohydride or and sodium borohydride.
Preferably, the inert gas be nitrogen or and helium or and argon gas.
Preferably, described accommodation section is cylindric.
Preferably, when ambient temperature reaches predetermined value, the membrane material is opened, and the chemical substance meets vapor
Burning, hydrogen is lighted.
Preferably, the chemical formula igniter is applied to nuclear power field.
Preferably, the chemical substance completely cuts off in home with vapor.
Compared with prior art, the utility model has and can spontaneously carry out igniting according to the change of external environment condition and disappear
Hydrogen, the beneficial effect inputted without extra power, when appearance has a power failure or stand-by power supply fails, remains able to effectively alleviation
Hydrogen risk
Brief description of the drawings
Fig. 1 is the schematic diagram for the chemical formula igniter for meeting the utility model preferred embodiment.
1- chemical formula igniters；
2- woven wires；
3- prevents the membrane material of vapor and air permeable；
4- meets the inflammable chemical substance of vapor.
Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model.
As shown in figure 1, the utility model preferred embodiment provides a kind of chemical formula igniter 1, the chemical formula point
Fiery device 1 includes the receiving portion being made up of woven wire 2.Preferably, described accommodation section is cylindric, cube etc., can be with

Placed inside described accommodation section and meet the inflammable chemical substance 4 of vapor and be filled with inert gas.Chemical substance is not
It can be spilt from woven wire.Preferably, the chance vapor inflammable chemical substance be calcium carbide or and potassium borohydride or and boron
Sodium hydride.Preferably, the inert gas be nitrogen or and helium or and argon gas.
The operation principle of chemical formula igniter 1 of the present utility model is, in nuclear power plant containment shell after generation accident, release
Go out hydrogen and vapor, temperature is raised, when temperature exceedes predetermined value, membrane material 3 is opened, and chemical substance 4 is met in woven wire 2
Vapor burns, and hydrogen is lighted, so as to alleviate Hydrogen risk.Discharge, or formed after chemical substance burning or with gaseous product
Solid product is resided in woven wire 2.
Preferably, the chemical formula igniter 1 is particularly suitable for use in nuclear power field.
Preferably, the chemical substance completely cuts off completely in home with vapor.
By the chemical formula igniter 1 of the utility model preferred embodiment, without extra power input.Ignition performance with
Environmental condition is relevant with therein chemistries.To meet water or vapor burningization easily occurs for used chemical substance 4
Learn material, and use adequate measure, than such as above-mentioned membrane material 3 so that the chemical substance 4 in home with vapor every
Absolutely, prevent from burning in home.After accident occurs in nuclear power station, temperature rise, vapor is produced, chemical formula igniting dress
Put 1 to light automatically, so that the hydrogen that ignites, alleviates Hydrogen risk.
The embodiment of each in this specification is described by the way of progressive, and what each embodiment was stressed is and other
Between the difference of embodiment, 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, related part is referring to method part illustration
.
Those skilled in the art can realize described function to each specific application using distinct methods, but
It is this realize it is not considered that beyond scope of the present utility model.
Obviously, those skilled in the art can be new without departing from this practicality to the various changes of utility model progress and modification
The spirit and scope of type.So, if these modifications and variations of the present utility model belong to the utility model claim and its
Within the scope of equivalent technologies, then the utility model is also intended to including these changes and modification.
