What the present embodiment was provided avoids the course of work of the infrared sulfur measuring instrument of air chamber pollution similar with embodiment three, different
Where be, under test gas from combustion tube 2 out after, sequentially pass through the first order except water filtration is removed in water filter 31 and the second level
After the dual eliminating water of device 32, then filter through first order dust removal filter 41, then pass through flowmeter 51 and flow controller 52,
Then filter again through second level dust removal filter 42, finally enter back into infrared pond 6 and tested.
What the present embodiment was provided avoids the infrared sulfur measuring instrument that air chamber pollutes by the way that gas drier 3 to be set to include
The first order is except water filter 31 and the second level are except water filter 32 is in interior two-stage drying device, and the first order removes water filter 31
With the second level except water filter 32 is perchloric acid magnesium types efficient water-removing filter, its drying effect can be effectively ensured, additionally, the
Two grades, except water filter 32 is by the way of lower end air inlet, upper end outlet, can be prevented effectively from small of drier magnesium perchlorate
Grain etc. is mixed under test gas, additionally, second level dust removal filter 42 is set up in the gas circuit lower end of flow controller 52, can be effective
Strengthen its dust removal and filtration effect, it is to avoid damage of the molecule to the grade of aspiration pump 7, reduce the deposition of other materials in infrared pond 6,
Further, the accuracy of its measurement result is effectively increased, its service life is substantially prolongs；Meanwhile, removed by setting up the second level
Dirt filter 42, has further elongated the distance of aspiration pump and flow controller, increases its buffering capacity, eliminates infrared sulfur measuring instrument
The liquefaction phenomenon of the minor amount of water in pipe-line system, and then avoid the metallic element in pipeline from getting rusty, additionally due to buffering capacity
Increase, gas flow regulation device is more stable, and then, the accuracy of its measurement result is improve to a certain extent.
Finally, the preferred embodiment of the present invention is these are only, protection scope of the present invention is not intended to limit.It is all this
Within the spirit and principle of invention, any modification, equivalent substitution and improvements made etc. should be included in the protection model of the present invention
Within enclosing.
