Description
The utility model belongs to measurement, technical field of measurement and test, relates to the analytical instrument that a kind of utilization is tested the concentration of tested gas the absorption intensity of infrared light, and particularly a kind of heteronuclear gas analyzer is with testing storehouse (G01J3/00).
Heteronuclear gas was analyzed in the past, adopted the analytical approach of atomic absorption spectrum usually.At first through grating beam splitting, make it to become monochromatic light by the light of light emitted.Adjust the angle of grating, just can obtain the monochromatic light consistent with each other with the spectral wavelength of tested gas, in case when having tested gas stream to cross test zone, will absorb a part of above-mentioned monochromatic light, and its absorption intensity is relevant with the concentration of the tested gas of the test zone of flowing through, according to this principle, just can measure the concentration change of relevant gas.Certainly in the time of will testing another kind of gas, just must to change the angle of grating, so that obtain and the spectral wavelength monochromatic light consistent with each other of this tested gas.Although this instrument has higher analysis precision and analyzes stability preferably, but this instrument is very expensive, it requires to have the machinery of a cover degree of precision to cooperate, drop on the wavelength band of infrared light because of the spectral wavelength of heteronuclear gas, and infrared light is sightless, the adjustment of infrared wavelength only sees that mechanical scale realizes, monochromatic spectral line scope is very narrow again, sensitive volume is arranged again in this narrower scope, so need again and again to adjust, only at the monochromatic light that adjusts very accurately on the basis, could guarantee analysis result accurately.Therefore this instrument is analyzed multicomponent gas at short notice very big difficulty, more impossiblely carries out many proximate analysiss simultaneously.
Certainly, heteronuclear gas is analyzed the method that also can adopt microphony to detect, but the employed instrument of microphony detection method need be changed different microsound probes when measuring different gas, so this instrument also can't carry out many proximate analysiss simultaneously at all, and its microsound probe is made difficulty, serviceable life is short, interchangeability is poor, debugging is complicated, a little less than the antijamming capability, therefore it is very strict to environmental requirement, just can not use in the place that vibratility is bigger, in a single day slight sound of movement is arranged on the cabinet, microsound probe just can be made mistakes.
The purpose of this utility model is to provide a kind of heteronuclear gas analyzer with the test storehouse, uses the heteronuclear gas analyzer in this test storehouse, and production cost is obviously reduced, and greatly improve serviceable life, but also has realized the purpose of many proximate analysiss simultaneously.
Task of the present utility model realizes that by following manner a kind of heteronuclear gas analyzer is with testing the storehouse, and its key is to have additional the calibrating gas storehouse between tested gas storehouse and light source.
Its design concept is: infrared spectrum is to be absorbed by heteronuclear gas, and a kind of specific gas only absorbs the spectrum of own institute corresponding wavelength certainly, in desirable concentration range,, make the infrared spectrum of a certain wavelength accomplish that absorptivity is possible near 100% in a certain period.For example, in a certain gas storehouse, fill the into CO of high concentration
2Gas if there is enough length in this gas storehouse, is adjusted to infrared light a desirable intensity, again just this gas storehouse can be CO
2The spectrum of pairing each absorbing wavelength of gas almost all absorbs, and this gas storehouse has just become CO
2The dedicated barrier storehouse of pairing each absorption spectrum of gas.As seen fill the into heteronuclear gas of other any one high concentration in this gas storehouse, just can become the dedicated barrier storehouse of pairing each absorption spectrum of this heteronuclear gas in this gas storehouse, we are referred to as the calibrating gas storehouse with this gas storehouse.If the infrared light of same intensity passes through CO respectively
2Calibrating gas storehouse and N
2Pass through identical tested gas storehouse after the calibrating gas storehouse more respectively, in case tested gas storehouse contains CO
2Gas just can obtain the infrared signal of two varying strengths in the back in tested gas storehouse, again because of nitrogen does not absorb infrared light, so just can try to achieve contained CO in the tested gas storehouse according to the infrared signal of above-mentioned two varying strengths
2The concentration of gas.
In like manner, utilize the different calibrating gas storehouses just can be (for example: CO to other heteronuclear gas
2, CO, SO
2, SO ... with gas in the various alkane) measure.
In order to satisfy the needs that carry out many proximate analysiss simultaneously, calibrating gas storehouse and tested gas storehouse preferably are provided with in pairs, and each calibrating gas storehouse and each tested gas storehouse are set in parallel in respectively on the frame of storehouse, be respectively equipped with air intake opening and gas outlet on each tested gas storehouse, each tested gas storehouse connects through wireway.
In order further to improve measuring accuracy, eliminate error at measurment, can set up a calibrating gas storehouse in addition again, corresponding to this calibrating gas storehouse a blank storehouse is set simultaneously.
Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail.
Fig. 1 is the utility model general structure synoptic diagram;
Fig. 2 is the another kind of structural representation of the utility model.
With reference to Fig. 1, infrared lamp 2 is fixed on the reflector 1, between tested gas storehouse 4 and infrared lamp 2, have additional calibrating gas storehouse 3, calibrating gas storehouse 3 is provided with in pairs with tested gas storehouse 4, as can be seen from Figure 1, calibrating gas storehouse 3 is provided with four altogether, and tested gas storehouse 4 also is provided with four, and each calibrating gas storehouse 3 and each tested gas storehouse 4 are set in parallel in respectively on the storehouse frame 5, be respectively arranged with valve 6 on each calibrating gas storehouse 3, then be respectively equipped with air intake opening 7 and gas outlet 8 on each tested gas storehouse 4, each tested gas storehouse connects through wireway 9, the rearward end in each tested gas storehouse 4 also is respectively arranged with photoelectric tube 10, changes electric signal into so that will penetrate the infrared light in calibrating gas storehouse 3 and tested gas storehouse 4.
