Specific embodiment
Embodiment 1 as shown in figure 1, the present embodiment is a kind of multi-functional formaldehyde examination system, 2 between the detection of an encapsulation
The concentration of formaldehyde that the interior detection of utilization formaldehyde survey meter 1 is filled in the air in 2 between detection is detected, in detection, will be treated
The sample of survey is put into 2 between detection, and so, the formaldehyde in testing sample will volatilize, and 2 between the detection full of sealing, and utilizes
Agitating device or alternate manner, allow the air to be measured between detection to be sufficiently mixed, and this is the institute as the density ratio air of formaldehyde is big
So that, after sample release formaldehyde, formaldehyde gradually can decline toward air lower floor, if the air formaldehyde above or below directly testing
During content, can there is larger error.In the present embodiment, the mouth equipped with pumping where equipment is by bottom, that is, air-breathing
Mouth 8, is extracted into bottom content of formaldehyde higher air using trachea 5 top of equipment with air pump 6, is discharged to from air vent 7
2 top between detection, air-flow are sufficiently mixed where top content of formaldehyde is less, pass through the probe of methylene oxide detecting instrument 1,
At this moment the formaldehyde contained by air surveyed is only accurately.Before detection, the air of equipment is taken away in advance in addition, reduces interference.Institute
It is also that detection is accurately crucial that formaldehyde examination probe degree of accuracy is high.In the present embodiment, formaldehyde survey meter 1 adopts highly sensitive light
Electric transducer.
In the present embodiment, in order to ensure that sample lays suitable, the 2 interior also placement sample stage 3 between detection, on sample stage 3
The light-source system 4 for producing UV light, electric filament lamp or other visible rays is installed by side, and light-source system 4 irradiates described sample stage 3, light source
System power supply 15 is arranged on outside between detection, is connected with light-source system 4 with power lead.It is so many in 3 top devices of sample
The light-source system 4 of light group is planted, different light can be set sample is irradiated, to test UV light, electric filament lamp, it is seen that light
Deng different absorbabilities of the light source to sample formaldehyde.
In the present embodiment, also including sample jar 9, sample jar 9 passes through gas outlet and the row respectively with air pump 6 of trachea 5
QI KOU 7 is communicated, and the trachea 5 between sample jar 9 and air pump 6 is additionally provided with valve 11.Flow instrument is additionally provided with trachea 5
10.Sample jar 9 in the present embodiment is connected on pumping guard system, can be with test sample to the absorption energy containing formaldehyde gases that flows
Power.As shown in figure 1, flow instrument 10 is provided in the Liang Ge branches on trachea 5 with sample jar 9, in the gas in 6 downstream of air pump
On the supervisor of pipe 5, air outlet slit 14 is additionally provided with, air outlet slit valve 13 is installed on air outlet slit 14, in addition, going out in air
Mouth 14 also has second valve 12 with flow instrument 10.Second valve 12 is closed before test sample first, while open air going out
Mouth valve 13, extracts the air between detection out with pumping .6 from air outlet slit 14.After the completion of open the second valve 12 and simultaneously close off
Air outlet slit valve 13, then carry out follow-up detection
Key in the present embodiment is formaldehyde survey meter, light is combined and extract system,
Formaldehyde measurement scope：0～300PPM
Gas flow scope：1～1000ml/min
Light power scope：0～1000w
Compared with conventional art, the present embodiment has the advantage that：
1. accuracy of detection is high
Due to the density ratio air of formaldehyde it is big, so after sample release formaldehyde, formaldehyde gradually can decline toward air lower floor,
If directly test above or below formaldehyde content of air when, can there is larger error.We lean on the ground of bottom in equipment
Mouth of the side equipped with pumping, is extracted into bottom content of formaldehyde higher air the top of equipment with air pump, and air-flow is through top first
It is sufficiently mixed where aldehyde is less, passes through the probe of methylene oxide detecting instrument, the formaldehyde contained by air at this moment surveyed is only
Accurately.Before detection, the air of equipment is taken away in advance in addition, reduces interference.Formaldehyde examination probe degree of accuracy used is high to be also
Detection is accurately crucial.
2. detection efficiency is high
With respect to general Analysis Methods for Formaldehyde, the dozens of minutes time of even several hours that needs having can just complete inspection
Survey, and this utility model is completed by only needing a few minutes, greatly reduce the testing time, improve detection efficiency.
3. have a safety feature
Conventional formaldehyde examination needs extra chemical drugss, some possible or poisonous and hazardous chemicals, not only wave
Take resource, pollute environment, also the body of personnel can be worked the mischief.This utility model is not required to reuse any chemical drugss, and
And equipment good airproof performance, some poisonous and hazardous chemical gas will not be revealed or there are other safety problems to produce.
4. multi-functional
Light in equipment can arrange uv light, it is seen that light, and three kinds of different light of electric filament lamp, every kind of light have three
Different shelves, can need to be optionally combined light according to difference.The flow of pumping can also control different according to actual needs
Flow, speed.Can be so that sample be put into sample jar, by adjusting air-flow through sample jar, the absorption of test sample PARA FORMALDEHYDE PRILLS(91,95).
