Technical field
The present invention relates to the safety management technology field of dangerization gas, more particularly to a kind of analysis side of dangerization gas potential safety hazard
Method.
Background technology
Existing dangerization gas sensing system, all only can just be circulated a notice of when dangerization gas concentration exceedes alarm concentration value,
But many potential safety hazards can be parsed out in low concentration, by taking combustion gas as an example, most gas pipeline is old or small
Rhegma brings faint combustion gas to leak, and its concentration is usually less than 10%LEL, or even gas combustion incomplete concentration during than cooking
Also lower, such as Fig. 2 is the sample record of certain kitchen gas concentration one day, from figure 2 it can be seen that most of sampling
The gas concentration that record display is measured is between 200ppm~600ppm, sometimes because gas combustion not exclusively increases to
Between 600ppm~1200ppm, because almost gas concentration is just circulated a notice of more than warning value 5000ppm, so, it is such low
Concentration combustion gas survival phenomenon will not for known to user, such low concentration be likely to be safe from harm (for example gas cylinder is placed on
Confined space, gas combustion is not exclusively accumulated), it is also possible to it is to have harm (such as gas pipeline, which has, slightly to corrode, can be by
Step expansion is corroded scope).If reducing alarm concentration value for these possible hidden danger, cause usually to alert, phase can be caused
The distrust that pass personnel alert for this.Therefore, should be when there is dangerization gas to there is leakage to be inclined to, early warning ahead of time is simultaneously handled, reduction
May occur the risk of disaster.
The content of the invention
The purpose of the present invention is that the defect for overcoming prior art to exist can predict the hidden danger of high risk there is provided a kind of
And notify related personnel to go to processing, to lift the precision of potential safety hazard detecting, and reduce the cost of potential safety hazard preventing and treating
