Description
Technical field
The present invention is the another core component in analytical instrument, instrument, applies to national defence, oil, chemical industry, gas, coke oven
Coal gas, drilling well, mining, environmental protection, quality inspection, colliery, refinery, nuclear energy, space flight, medical, biogas, smelt, oxygen processed, semiconductor,
Quality analysis, the process analysis fields such as printing and dyeing, welding.
Technical background
The currently detector in many analysis industry instruments, instrument, using non-explosion-proof casing, does not add spark arrester,
Check-valves, without explosion prevention function, in the case that detector is in work, high pressure cartridge produces arc light, if in inflammable-explosive
In fried gas or scene, is very easy to light fuel gas.Current many detector sensitivity for analysis all in ppm levels, analyze gas
The body component excessively limit, far from the analysis for meeting gaseous impurity.This detector overcomes this difficulty, and test limit is as little as
0.1ppb poles, meet industry, national defence, the technical demand of scientific research.
The content of the invention
The present invention realizes the flexible design of multi-scheme multi-method, used；It is researching and developing, being real for explosion-proof and non-explosion-proof industry
Test, produce, quality inspection, instrument, the explosion-proof helium discharge detector in instrument.This detector is the another core in analytical instrument, instrument
Heart technology, it is widely used in the sensor of chromatographic field.National explosion-proof criteria and international explosion-proof criteria is fully achieved in one kind, can be
Various explosion-proof occasion work.Detector housing has the function of flame proof.Detector entrance has check-valves, and purpose is exactly detector chamber
When the air pressure of body uprises the pressure more than gas access suddenly, check-valves blocks air-flow by the way that material is thus formed can only immediately
The function that air inlet will not flow backwards is realized explosion-proof.Analyze gas or purge gas helium enters detector quartz chamber body and powered high pressure
Under cartridge collective effect, ionized region is produced, the collision of ion and ion produces a branch of corona shwoot arc light and forms ion, photon,
Ion, photon produce energy, the motion process of ion and ion high-speed impact under the physical phenomenon high speed motion of high potential
Middle generation electric current sends electric wave, and the collector through collecting region, which is collected, produces current signal or voltage signal.
Helium has inflow detector, just there is a reason of outflow, helium and the tested gas with impurity ionized region by from
Spark arrester is flowed into after change, after ionized shock and loses energy, and by flow sensor, the flow passed through to air-flow carries out real-time
Monitoring, under can so ensureing whether gas flow is maintained at identical conditions during analysis, this time analysis result reaches more
Add accurate impression, more science.Small volume of the cavity of detector itself, purge gass all the way are devised in scheme, accelerate quartz
The dead angle purging of cavity, purpose are exactly that pressure-fired is formed in detector cavity and produces more ions, are thus had just
Pressure purging function, also cavity form more stable electron ion.
This detector is under conditions of closed, and in 400 DEG C of high temperature, under 10Mpa air pressure, leakage is less than 0.001mL
Daily, 100 working days are without deformation；This detector canonical reference：《Chemical industry on-line gas chromatography》HG/T4095-2009、

Technical principle
Its principle of this detector is exactly to be insulated in the case of completely closed, while in height in high resistance detector body, by（1）
Purge gass helium passes through（2）Check-valves is through entering either（17）Analysis gas is directly entered quartz cavity arrival（30）After region of discharge.When
（24）High pressure cartridge with（11）Intensify cartridge all carry high-tension electricity in the case of, discharge electrode（Cartridge or pole pipe）Voltage be greater than
400 volts of high pressures, intensify pole tension and can not be equal to 0 volt, while on the premise of the concentration Reinheitszahl of helium is greater than certain value, now
Region of discharge two-stage can just produce（30）Ionized region.Under being acted at high-tension the two poles of the earth, the corona for producing a branch of high-energy forms arc
Light, aura produce photon, electronics, ion simultaneously.Move and produce in high-tension electric field high speed（20）Ionized region is tightly attached to
In quartz chamber body.
When helium is intensified by a large amount of helium atoms of ionized region, the helium atom being intensified and electron collision generation helium ion are steady
Fixed DC pulse turns into metastable state.It is positive and negative that the helium that collector spout sprays or the gas with impurity are intensified generation again
Electric charge, it is ionized in ionized region and produces high-speed motion, hits generation energy, produced by during this releases energy
Curtage turns into signal.
When analyzed drive of the gaseous impurity through helium, into the ionization of detector ionized region, it is intensified, pure helium
Caused helium atom has high-energy, if impurity molecule or atom with separation bring into ionized region occur inelastic collision or
Accelerate collision so that the energy dropoff of helium atom or enhancing, now add an appropriate voltage on extremely in intensifying for region of discharge, be ionized
Atom formed charge order entrance（31）Collecting region quilt（14）Nozzle collector passes out.By（28）Collector, record
Instrument or miscellaneous equipment are recorded to form electric wave signal.Foreign atom, the molecule being ionized, it can obtain with standard specimen concentration into just
Than or the electric current, the voltage signal that are inversely proportional.The complete electric wave signal of a width is obtained after processing of circuit, this just becomes tested miscellaneous
The Wave crest and wave trough spectrogram of matter content value.
Electric wave signal caused by the content of this detector analysing impurity is directly proportional to standard sample gas or inverse ratio, detector
The sensitivity of linear wider detection is higher, and test limit is lower.High voltage power supply, intensify power supply in the case where condition is certain,
The purity of helium is to determine that detector appraises and decides quantitative basis, is to provide the Main Basiss of 1 boundary's point of analysing impurity content.
The sensitivity of detector and high voltage power supply, intensify supply voltage, jet size, cavity volume, insulaion resistance, cartridge
Or pole pipe material spaced position, helium purity are relevant, voltage more High Linear is wider, and frequency is faster, and sensitivity is higher.
Embodiment.
