The inlet end of described nitrogen pipeline 5 is provided with the valve 6 for controlling nitrogen flow.
The process in early stage, the sampling method that detect industrial germanium tetrachloride are:
1. the pre-service of nitrogen pipeline and process bottle
For getting rid of air in nitrogen pipeline 5 and process bottle 3 and pollutant, avoid it to enter the sample cell 2 pairs of testing results when sampling and produce interference, before sampling, first need carry out the pre-service of nitrogen flushing and rinse to nitrogen pipeline 5 and process bottle 3, disposal route is as follows:
The purging of 1.1 nitrogen pipelines and process bottle
Before cleaning, need purge nitrogen pipeline 5.(namely two-port valve is opened to the direction of nitrogen pipeline 5 two-port valve on germanium tetrachloride bottle for material 1, sample cell 2, receiving bottle 4 to be all arranged on short-circuit condition, nitrogen pipeline 5 is directly communicated with, nitrogen is not by germanium tetrachloride bottle for material 1, sample cell 2 and receiving bottle 4), open nitrogen and control nitrogen flow by valve 6,10min is purged to nitrogen pipeline 5.
1.2 germanium tetrachloride bottle for material fill nitrogen pressurization
After blowing pipeline terminates, close nitrogen, receiving bottle 4 pressure release 30s, then the two-port valve on germanium tetrachloride bottle for material 1 drain pipe is arranged on short-circuit condition, two-port valve in draft tube is arranged on channel status, and (namely two-port valve is opened to the direction of germanium tetrachloride bottle for material 1, nitrogen pipeline 3 can not be directly communicated with, nitrogen enters germanium tetrachloride bottle for material 1), open nitrogen and nitrogen 10 ~ 15s is mended to germanium tetrachloride bottle for material 1, the nitrogen pressure in germanium tetrachloride bottle for material 1 is made to be 1 ~ 2Bar, the excessive binder excessive velocities easily causing the later stage of pressure, more germanium tetrachloride material can be wasted on the one hand, process bottle 3 can be made to be impacted when shifting germanium tetrachloride material to process bottle 3 on the other hand and break, jeopardize personal safety.
Germanium tetrachloride material is pressed onto process bottle by 1.3
Germanium tetrachloride bottle for material 1 is mended after nitrogen terminates, nitrogen is closed by valve 6, two-port valve in germanium tetrachloride bottle for material 1 draft tube is switched to short-circuit condition, two-port valve on germanium tetrachloride bottle for material 1 drain pipe is slowly opened, makes the germanium tetrachloride material in germanium tetrachloride bottle for material 1 under the effect of pressure reduction, enter process bottle 3.
The rinse of 1.4 process bottles
When the press-in of germanium tetrachloride material processes 20% place of bottle 3 volume, carry out the cleaning processing bottle 3.Two-port valve on germanium tetrachloride bottle for material draft tube and drain pipe is all set to short-circuit condition, slow Open valve 6, after germanium tetrachloride material residual in nitrogen pipeline 5 being all pressed into process bottle 3, closing nitrogen, process bottle 3 is rocked gently and carries out rinse.
After rinse completes, two-port valve on receiving bottle 4 feed tube and escape pipe is all switched to channel status, opens nitrogen, process bottle 3 is tilted, make the discharging opening of the germanium tetrachloride material submerged impinging jet bottle 3 in process bottle 3, the germanium tetrachloride material rinse liquid of cleaning treatment bottle 3 is all pressed in receiving bottle 4, closes nitrogen, after receiving bottle 4 pressure release 30s, again the two-port valve on receiving bottle 4 feed tube and escape pipe is switched to short-circuit condition, open nitrogen, nitrogen pipeline 5 is purged, then closes nitrogen.
2. process the early stage of germanium tetrachloride, sample
For ensureing the accuracy of germanium tetrachloride material sample detection result, need carry out nitrogen flushing process in early stage to the detection sample of germanium tetrachloride material, the operation steps of process is:
Germanium tetrachloride material is pressed onto process bottle by 2.1
Two-port valve on germanium tetrachloride bottle for material 1 drain pipe is slowly opened, makes the germanium tetrachloride material in germanium tetrachloride bottle for material 1 under the effect of pressure reduction, enter process bottle 3.
2.2 pairs of germanium tetrachloride materials carry out nitrogen flushing process
After 50 ~ 80% of germanium tetrachloride sample press-in process bottle 3 volume, the two-port valve on germanium tetrachloride bottle for material 1 draft tube and drain pipe is arranged on short-circuit condition.Open nitrogen, according to the flow velocity of germanium tetrachloride material in nitrogen pipeline 5, control valve 6, germanium tetrachloride material in pipe is all pressed in process bottle 3, and by control valve 6, make the germanium tetrachloride material in process bottle 3 remain micro-and seethe state, duration of ventilation is 30 ~ 60min, realizes the nitrogen flushing to germanium tetrachloride material in process bottle 3.
The rinse of 2.3 sample cells
In order to avoid the impurity in sample cell 2 or detection residue are to the interference of testing result, need before sampling to carry out rinse to sample cell 2.First by germanium tetrachloride bottle for material 1, two-port valve on receiving bottle 4 is all arranged on short-circuit condition, then the two-port valve on sample cell 2 feed pipe and discharge nozzle is arranged on channel status, open nitrogen, process bottle 3 is tilted, the germanium tetrachloride material in process bottle 3 is made to flood discharging opening, germanium tetrachloride material in process bottle 3 is compressed into sample cell 2, after sample cell 2 discharge nozzle has germanium tetrachloride material to flow out, close nitrogen, two-port valve on receiving bottle 4 feed tube and escape pipe is switched to channel status, open nitrogen again, nitrogen is closed after germanium tetrachloride rinse liquid in sample cell 2 is all pressed into receiving bottle 4, on receiving bottle 4 two two-port valve is switched to short-circuit condition again.
2.4 sample cell samplings
Again open nitrogen, process bottle 3 is tilted, the germanium tetrachloride material in process bottle 3 is made to flood gas outlet, germanium tetrachloride material in process bottle 3 is compressed into sample cell 2, after the discharge nozzle of sample cell 2 has germanium tetrachloride material to flow out, the two-port valve on sample cell 2 feed pipe and discharge nozzle is all switched to short-circuit condition, remaining germanium tetrachloride material in bottle 3 and nitrogen pipeline 5 will be processed with nitrogen and be pressed in receiving bottle 4, close nitrogen, switch to short-circuit condition to after receiving bottle 4 pressure release 30s.Finally regulate all valves on germanium tetrachloride bottle for material 1, sample cell 2, receiving bottle 4 to be in short-circuit condition, open nitrogen, 15min is purged to nitrogen pipeline 5 and clears up.
Testing result is as follows:
According to GB/T 6040 infrared spectrum analysis general rule, use Fourier infrared spectrograph to carry out infrared detection to the germanium tetrachloride material in sample cell 2, detect spectrogram as shown in Figure 2,3.
Wherein Fig. 2 is the infrared spectrum not carrying out germanium tetrachloride sampling process in early stage, as can see from Figure 2: wave number 2985cm
-1to 2710cm
-1peak connect into one saturated through peak, wave number 3322cm
-1, 3301cm
-1slightly highlight through peak, cause and cannot judge wave number 2985cm
-1and 2710cm
-1, 3322cm
-1, 3301cm
-1the transmitance through peak.
Fig. 3 uses device of the present utility model to carry out the infrared spectrum after process in early stage to thick germanium tetrachloride sample, wave number 2985cm
-1, 2710cm
-1what connect is saturated obvious through peak through separating in two of peak, 3322cm
-1, 3301cm
-1wave number high-visible through peak, reading that therefore can be correct, through peak value, obtains sample and detects data accurately.
Therefore, after adopting the detection sample of method to industrial germanium tetrachloride material passing into nitrogen to carry out process in early stage, effectively can eliminate the foreign gases such as chlorine free in sample and hydrochloric acid to the interference measured, make the detection data that obtain more accurately and reliably, thus have laid a good foundation for the quality testing analysis of industrial germanium tetrachloride.
