Description
Technical field
The utility model relates to a kind of gas chromatographs, and more particularly, to it is a kind of can automatic ignition gas-chromatography
Instrument.
Background technique
For the needs for adapting to Economic Sustainable Development Strategy, the increase for the energy that China is put into environmental protection, theory
Reinforcement, the proposition of appearance and the urban planning of all kinds of environmental regulations.The monitoring of VOCs and control increasingly by
Extensive concern.Influence of the pollution sources to surrounding enviroment and how to ensure the reliable for operation for the treatment of facility, it is desirable to provide a large amount of
Accurate and reliable and continuous timely environmental monitoring foundation.
With the development of technology, before artificial sample, sample presentation, the monitoring method of lab analysis are substituted, should
Kind method not only takes a lot of work, is time-consuming, but also accuracy is low, analysis time is long, data available is few, and present continuous monitoring is not achieved and wants
It asks.In order to preferably reflect variation status and rule of the air pollution on room and time, diffusion tendency to pollutant and
Supposition and judgement are made in influence, and the advantage of on-line monitoring equipment is very important.
The stability of O&M efficiency and the field device operation at the scene of how improving needs prominent for on-line monitoring class equipment
Two broken main points.
Using the monitoring class equipment of GC-FID principle as common type in VOCs on-line monitoring equipment, there is analyst coverage
Extensively, high sensitivity, the advantages that qualitative and quantitative analysis can be done.
The principle of this analysis method based on GC-FID, equipment, just can be into only in the case where detector is combustion state
Row DATA REASONING and analysis work.Therefore how the burning work inside detection trigger device just becomes abnormal important.
Previous monitoring device, the triggering of firing action are mostly to form closed circuit by artificially clicking " ignition switch ",
Two igniting needle-dischargings above control detector form the high-voltage pulse of kilovolt, carry out electric sparking.There are two for this mode
A disadvantage, first disadvantage are in equipment running process, if because (abnormal power-down, gas source are insufficient, sample air humidity degree for extraneous factor
The reasons such as big) or internal cause (airway blockage, gas source are more abnormal etc. than setting) cause to stop working, can not voluntarily carry out firing action
Triggering, it is necessary to which operation maintenance personnel carries out on-site maintenance, increases burden for O&M efficiency and cost.Second disadvantage is high pressure
Pulse firing can generate hundreds of voltage in the moment of igniting, be affected to the circuit inside equipment, meeting that What is more
The case where burning out board appearance forms risk to the stable operation of equipment.
So research is a safe and has automatic ignition, easy to operate, economic and practical gas chromatograph in volatility
Monitoring organic compounds research field has great importance.
Summary of the invention
In order to solve the above-mentioned technical problem, the application is proposed.Embodiments herein provides one kind can automatic ignition
Gas chromatograph.
The technical solution of the utility model is: it is a kind of can automatic ignition gas chromatograph, the gas chromatograph includes:

Heart control unit, igniting execution unit, wherein pressure control unit is connect with hydrogen source gas, air gas source, carrier gas gas source, master control
Board is connect with pressure control unit, flame-out monitoring unit and centralized control unit respectively, and centralized control unit and igniting execute
Unit connection.
Preferably, wherein the igniting execution unit is heating wire or cartridge element.
Preferably, wherein the flame-out monitoring unit is thermoelectricity occasionally temperature sensor.
Preferably, wherein the igniter further include: manual firing's button.
The utility model having the beneficial effect that through two kinds of ingenious collocation of sparking mode compared with prior art, is retaining
Increase automatic firing function on the basis of traditional manual ignition.It is more complete in logic compared with other current chromatographs,
Functionally more comprehensively.When chromatographic working environment is that longtime running requires non-stop run, the method can be at nobody
When equipment caused by the reasons such as abnormal power-down, gas source shakiness because stopping working under the premise of O&M, guarantee that surrounding running environment restores normal
When, equipment can resume operation state automatically, reduce the frequency artificially safeguarded；And maintenance difficulties reduce, the igniting of this method
System is modularization, and wherein control unit, monitoring unit and execution unit can independent dismounting and changes.
Detailed description of the invention
Fig. 1 be can automatic ignition gas chromatograph structural schematic diagram.
Fig. 2 be can automatic ignition gas chromatograph automatic ignition flow chart.
Specific embodiment
Keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, below in conjunction with the utility model
Attached drawing in embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to Fig. 1, in the utility model embodiment, gas chromatograph include: hydrogen flame detector 1, hydrogen source gas 2,
Air gas source 3, carrier gas gas source 4, pressure control unit 5, flame-out monitoring unit 6, master control board card 7, centralized control unit 8, igniting
Execution unit 9, wherein pressure control unit 5 is connect with hydrogen source gas 2, air gas source 3, carrier gas gas source 4, and master control board card 7 is distinguished
It is connect with pressure control unit 5, flame-out monitoring unit 6 and centralized control unit 8, centralized control unit 8 and igniting execution unit 9
Connection.
Using the present embodiment, cooperated by the connection of misfire detection unit, master control board card, execution unit of lighting a fire, Ke Yi
Under the premise of unmanned O&M equipment because when the reasons such as abnormal power-down, gas source shakiness caused by stop working when, guarantee that surrounding running environment is extensive
When multiple normal, equipment can resume operation state automatically, reduce the frequency artificially safeguarded.
The hydrogen flame detector 1 is a kind of mass flow rate sensitive detector, is most popular one kind in gas chromatograph,
Have the characteristics that structure is simple, has excellent performance, is reliable and stable, is easy to operate.
The hydrogen source gas 2 provides the primary combustion gas of detector burning.
The air gas source 3 provides the main combustion-supporting gas of detector burning, and it is successful to collectively constitute igniting with hydrogen source gas
Preparatory condition.
Sample to be tested is successfully brought into detector and detected by the carrier gas gas source 4.
The pressure control unit 5, this element are pressure controller group, and control hydrogen, air, nitrogen output are specified respectively
Flow.
