Description
Technical field
The utility model relates to Gas Thickness Detecting Technology field, particularly a kind of gas concentration detection apparatus.
Background technology
It is colourless, odorless under vikane normal temperature and pressure, diffusion permeability is extremely strong, features such as there is broad spectrum disinfestation, dosage is economized, low, the desinsection speed of residual quantity fast, the loose gas time is short, low temperature is easy to use, germination percentage is not affected and toxicity is lower, therefore be widely used in warehouse, freighter, container and buildings, reservoir dam, termite control and gardens to survive the winter the control of insect, the tree moth dryness insect that lives, such as, in customs inspection quarantine field, vikane as fumigant, for the control to harmful organism, crops and secondary product stifling etc.
Sulfuryl fluoride gas has certain toxic action to human body, and therefore, we strictly will monitor sulfuryl fluoride gas concentration that is residual, trace, to ensure personal safety.Meanwhile, vikane is also a kind of potent greenhouse gases, the serious greenhouse effect that can cause environment, and people need to monitor the vikane of trace, prevent the pollution of the environment.
Infrared Detection Method utilizes sulfuryl fluoride gas to carry out measurement of concetration in the light absorption of mid infrared region (6.82 ~ 9 μm), when a branch of constant infrared light of 6.82 ~ 9 μm passes through the medium containing sulfuryl fluoride gas, the energy of light can be absorbed by sulfuryl fluoride gas, luminous flux is attenuated, measure the luminous energy attenuated, the concentration of sulfuryl fluoride gas can be obtained.The application of this method is comparatively general, but because region of ultra-red also exists the absorption spectra of other gases when measuring, such as moisture, carbon dioxide etc., cause the accuracy of detection of vikane and lower limit to be interfered.
Utility model content
The purpose of this utility model is, provides a kind of structure simple, easy to use for the deficiencies in the prior art, can detect the gas concentration detection apparatus of high-temperature gas concentration exactly.
To achieve these goals, the technical scheme that the utility model adopts is as follows: a kind of gas concentration detection apparatus, comprising: sampler, sucting, inclined hole, airscoop shroud, high-pressure pump, heating part, condenser, permeable membrane, flowmeter, infrared detector, data analysis unit, information display unit, alarm; Sampler is connected with sucting, inclined hole is offered at the inwall of sucting, be installed into gas hood at the outer wall of sucting inclined hole is covered, airscoop shroud communicates with high-pressure pump, sucting is connected with one end of heating part, the other end of heating part is connected with condenser, one end of condenser is connected with permeable membrane, permeable membrane is connected with flowmeter, one end of flowmeter is connected with infrared detector, infrared detector is connected with data analysis unit, and information display unit is connected with data analysis unit all respectively with alarm.
The rectangular in cross-section of described airscoop shroud.
Described heating part is provided with heating plate.
The beneficial effects of the utility model are, this gas concentration detection apparatus effectively can remove the moisture in gas, improve accuracy of detection, and structure is simple, is easy to carry.
Accompanying drawing explanation
Fig. 1 is this gas concentration detection apparatus structural representation.
Above-mentioned number in the figure is described as follows:
1---sampler; 2---sucting; 3---inclined hole; 4---airscoop shroud; 5---high-pressure pump; 6---heating part; 7---condenser; 8---permeable membrane; 9---flowmeter; 10---infrared detector; 11---data analysis unit; 12---information display unit; 13---alarm.
Embodiment
The technical solution of the utility model is described further by specific embodiment below in conjunction with accompanying drawing.
A kind of gas concentration detection apparatus, comprising: sampler 1, sucting 2, inclined hole 3, airscoop shroud 4, high-pressure pump 5, heating part 6, condenser 7, permeable membrane 8, flowmeter 9, infrared detector 10, data analysis unit 11, information display unit 12, alarm 13, sampler 1 is connected with sucting 2, inclined hole 3 is offered at the inwall of sucting 2, be installed into gas hood 4 at the outer wall of sucting 2 inclined hole 3 is covered, airscoop shroud 4 communicates with high-pressure pump 5, sucting 2 is connected with one end of heating part 6, the other end of heating part 6 is connected with condenser 7, one end of condenser 7 is connected with permeable membrane 8, permeable membrane 8 is connected with flowmeter 9, one end of flowmeter 9 is connected with infrared detector 10, infrared detector 10 is connected with data analysis unit 11, information display unit 12 is connected with data analysis unit 11 all respectively with alarm 13.
Concrete operations principle is as follows: collect gas to be measured by sampler 1, gases at high pressure are passed into sucting 2 by inclined hole 3, sucting 2 is made to form inside high pressure, because inner and outer air pressure is different, outside gas is just inhaled in sucting 2, and gases at high pressure can carry out preliminary cooling to high-temperature gas.Gas is heated by heating part 6 afterwards, closed circuit is formed again by efficient condenser 7 and permeable membrane 8, remove the moisture in gas to be measured, after hydrone is discharged, gas to be measured is discharged by permeable membrane 8 and enters flowmeter 9, gas to be measured is able to current stabilization in flowmeter 9, infrared detector 10 is entered with stable flow velocity, the concentration obtaining detecting is by data analysis unit 11, gas concentration by analysis judges whether to exceed standard as requested, if exceed standard, alarm 13 sounds, and information display unit 12 carries out data collection process, is finally shown.
