Abstract
The utility model relates to an infrared pollution gas sampling device, which comprises a front filter lens, a gas chamber, a gas inlet, a gas outlet, a back filter lens and a sealing ring. The filter lens is hermetically connected with the gas chamber through the sealing ring, the gas inlet is welded on the gas chamber and is close to the end of the front filter lens, the back filter lens is hermetically connected with the gas chamber through the sealing ring, and the gas outlet is welded on the gas chamber and is close to the end of the back filter lens. The form of sealed sampling is adopted and minimization of sampling amount is realized. Convenience and accuracy in sampling are adequately considered. Meanwhile, the filter lenses are respectively arranged at the in-end and the out-end of an infrared light source, so that interference of an interference light source to a measuring spectrum is effectively isolated, and the accuracy of information reflected by the spectrum is guaranteed in a sampling output link.
Description
Technical field
The utility model relates to a kind of dusty gas sampler, particularly to dusty gas SF
6Infrared dusty gas sampler.
Background technology
Along with China's rapid economy development; The air pollution emission problem highlights; Atmospheric pollution presents the compositeness pollution that multiple pollutant acts on simultaneously, and pollution range expansion, and particularly tangible regional pollution characteristic appears in big city crowd area; Health, the ecosystem and climate change are constituted a serious threat and influence, become the great bottleneck factor of restriction China sustainable economic development.
Usually use two types of devices and supporting being used for of dusty gas analyser that the atmospheric pollution situation is carried out overall monitor at present both at home and abroad.One type is and the supporting suitable sampler of open light path face source emission gas analyzer; Promptly do not collect dusty gas; But the dusty gas zone is provided with the light source R-T unit, and the passage that directly utilizes dusty gas zone to form is analyzed the spectrum that wherein dusty gas composition forms; Confirm the composition of dusty gas, to sampling existence randomness, instability and the inaccuracy of dusty gas.Another kind ofly be and the matching used sealed type sampling device of gas composition analyser; Thereby but exist sampling amount big, can not effectively isolate disturbance and cause defectives such as spectrum reflection data are inaccurate; Simultaneously, for polluting the face source emission, as petrochemical complex plant area, bulky refuse handle, this type of uncontrollable discharge source and the monitoring in loss source such as large-scale plant and petroleum gas storage and transport station; The ineffective activity that sampling amount causes operation to be suitable for greatly can not satisfy the needs that real procedure is operated.
Summary of the invention
The infrared dusty gas sampler of the utility model; Take the form of sealing sampling and realized minimizing of sampling amount; Convenience, the accuracy of operation sampling have been taken into full account; With ejecting end filter glass is set respectively through inject end at infrared light supply simultaneously, effective isolation jamming light source interference that measure spectrum is produced, guaranteed that from the sampling output element spectrum reflects the accuracy of information.
This infrared dusty gas sampler; Comprise preceding filter glass, air chamber, inlet end, outlet side, back filter glass, O-ring seal; Wherein, said before filter glass be tightly connected through O-ring seal and air chamber, inlet end is welded on the air chamber and near preceding filter glass one end; Said back filter glass is tightly connected through O-ring seal and air chamber, and the outlet side is welded on the air chamber and near back filter glass one end.Said air chamber is preferably the casting air chamber one time, and preferred stainless steel is processed.For reducing the diffuse reflection of IR in the air chamber, it is pitted skin that air chamber is preferably inwall simultaneously.For the I of air chamber that minimizes that realizes sampling amount realizes that volume is 50ml.Whole infrared dusty gas sampler has good leakproofness, and the sampling dusty gas can be accomplished the function of sampling, spectrum output through inlet end normal pressure pattern air inlet chamber of making a bet in pattern of pressure or when opening the outlet side.
This infrared dusty gas sampler has the following advantages:
1, this device has been realized the sealing assembling through before and after air chamber, being provided with respectively between preceding filter glass, back filter glass, air chamber one-shot forming and each ingredient; Guaranteed that fully the inner IR of air chamber forms the influence that spectrum does not receive the external interference light source, guaranteed the accuracy of spectrum reflection information from the sampling output element.
2, this device volume is little, has solved the big technical barrier that waits of sampling amount in the prior art, has realized the convenience of operation, is particularly suitable for laboratory operation and uses.
Description of drawings
The infrared dusty gas sampler of Fig. 1 structural drawing.
Among the figure:
1. preceding filter glass 2. air chambers 3. inlet ends 4. outlet sides 5. back filter glass 6. O-ring seals
Embodiment
Shown in Figure 1; This infrared dusty gas sampler, filter glass 1, air chamber 2, inlet end 3, outlet side 4, back filter glass 5, O-ring seal 6 before comprising, wherein; Filter glass 1 is tightly connected through O-ring seal 6 and air chamber 2 before said; Inlet end 3 is welded on the air chamber 2 and near preceding filter glass 1 one ends, and said back filter glass 5 is tightly connected through O-ring seal 6 and air chamber 2, and outlet side 4 is welded on the air chamber 2 and near back filter glass 5 one ends.Whole infrared dusty gas sampler has good leakproofness, and the sampling dusty gas can be through inlet end 3 normal pressure pattern air inlet chamber 2 of making a bet in pattern of pressure or when opening outlet side 4.Outside infrared light supply sends infrared light; Filtration through preceding filter glass 1; Got rid of disturbance and got into air chamber, comparatively pure infrared light is injected air chamber 2, obtains the peculiar spectrum of corresponding dusty gas through the reflected refraction of dusty gas molecule; Via back filter glass 5 spectral information is delivered to the gas composition analyser that matches with it again, thereby this spectrum analysis is drawn the component information of dusty gas.Back filter glass 5 has also played and has stoped disturbance to get into the effect of air chamber 2 simultaneously.Through filter glass 1 before air chamber 2 front and back are provided with respectively, back filter glass 5, guaranteed that fully air chamber 2 inner IRs form the influence that spectrum does not receive the external interference light source, and the function that comparatively accurately completion is sampled on this basis, spectrum is exported.
Said air chamber 2 is preferably the casting air chamber one time, and preferred stainless steel is processed, and the stable performance that keeps this equipment on the one hand can reduce the possibility that reflects with dusty gas on the other hand as far as possible, particularly to dusty gas SF
6Practicality, stability stronger.For reducing the diffuse reflection of IR in the air chamber 2, it is pitted skin that air chamber 2 is preferably inwall simultaneously.Be to realize minimizing of sampling amount, the I of air chamber 2 realizes that volume is 50ml.
Through above structural design, this infrared dusty gas sampler has solved in the prior art that sampling amount is big, operation inconvenience, be subject to jamming light source influence, poor stability shortcoming.
