The concrete job step of phase separator of the present invention is as follows:
(1) ready-packaged joint 18 is communicated with on the metal hose with vacuumizing with gas sample bottle top ready-packaged joint 1; Gas sample bottle bottom ready-packaged joint 3 is communicated with sampling-separator(-ter) 5 top ready-packaged joints 4; First T-valve 6 is placed 6b, sampling-separator(-ter) 5 and separator(-ter) 8 are connected; Second T-valve 16 is placed the centre position, second T-valve is closed; The 3rd T-valve 10 is placed the centre position, the 3rd T-valve is closed.Adopt vacuum pump to vacuumize by the sampling unit that vacuumizes 19 pairs of gas sample bottles 2 of metal hose, sampling-separator(-ter) 5 and separator(-ter) 8 and be connected to form.After vacuumizing end, gas sample bottle bottom ready-packaged joint 3 is disconnected with sampling-separator(-ter) top ready-packaged joint 4.
(2) first T-valve 6 is placed 6a, make sampling-separator(-ter) 5 enter pipe 7 and be connected with water sample; To sample again-separator(-ter) top second T-valve 16 places 16b, and sampling-separator(-ter) 5 is communicated with water sample effuser 17.Carry out water sampling, water sample enters pipe 7 through water sample and enters sampling-separator(-ter) 5, flows out from water sample effuser 17, measures by 15 pairs of TWS of thermometer.
(3) treat that water samplings meet the requirements in the sampling-separator(-ter) 5 after, second T-valve 16 is placed the centre position, second T-valve 16 is closed; First T-valve 6 is placed 6b, sampling-separator(-ter) 5 is communicated with separator(-ter) 8, owing to be negative pressure of vacuum in the separator(-ter) 8, the water samples in the sampling-separator(-ter) 5 flow in separator(-ter) 8 lower cavity at this moment, and contained gas is emanated in sampling-separator(-ter) 5 through vacuum in the water sample;
(4) second T-valve 16 is placed 16a, sampling-separator(-ter) 5 is communicated with bubbling pipeline branch line; Open bubbled gas input pipe 13, the nitrogen of certain pressure is blown into sampling-separator(-ter) 5 through gas meter 12, second T-valve 16 from sampling-separator(-ter) top.Because being blown into of nitrogen causes sampling-separator(-ter) 5 internal pressures to be higher than separator(-ter) 8 internal pressures, the residue water sample all is blown in the separator(-ter) 8 under the driving of pressure reduction in the sampling-separator(-ter) 5;
(5) second T-valve 16 is placed the centre position, second T-valve 16 is closed; Separator(-ter) bottom the 3rd T-valve 10 is placed 10b, and nitrogen enters in separator(-ter) 8 lower cavity through bubbled gas input pipe 13, the 3rd T-valve 10, bubbling element 9, and water sample is carried out bubbling.Regulate the bubbling flow by gas meter 12,, reach certain value until force value and (after 0.2～0.3MPa), the 3rd T-valve 10 is placed the centre position, close the bubbling pipeline, and write down this pressure value P by tensimeter 14 measuring system pressure.And first T-valve 6 placed the centre position, first T-valve 6 is closed.To sample-separator(-ter) 5 leaves standstill certain hour (0.5～3 minute) so that its internal gas mixes.
Because the gas chromatograph analysis needs sample to have certain malleation, system's resulting pressure must reach certain value (0.2～0.3MPa).
(6) gas sample bottle bottom ready-packaged joint 3 is connected with sampling-separator(-ter) top ready-packaged joint 4, because in the gas sample bottle 2 is negative pressure of vacuum, gases in the sampling-separator(-ter) 5 enter gas sample bottle 2 after sampling-separator(-ter) 5 and gas sampling jar 2 pressure reach balance, disconnect being connected of ready-packaged joint 3 and ready-packaged joint 4, remove gas sample bottle 2, carry out gas chromatographic analysis.
(7) separator(-ter) bottom the 3rd T-valve 10 is placed 10a, the water sample in the separator(-ter) 8 is through 11 dischargings of water sample delivery pipe.
Adopt gas chromatograph to analyze to collecting gaseous sample to be measured.This gaseous sample to be measured is by nitrogen and contained gas composition in the isolated water sample of phase separator.By external standard method or correction normalization method, can know contained gas concentration in the interior water sample of gaseous sample to be measured.
Usually adopt following formula to calculate under the status of criterion contained gas concentration in the water sample:
In the formula, C
gBe contained gas concentration in the water sample under the status of criterion, cm
3Gas/g water;
C is that gas chromatographicanalyzer records contained gas concentration percent by volume in the interior water sample of gaseous sample to be measured;
V is air phase volume (volume of sampling-separator(-ter) 5, cm
3);
The quality of water in the sampling-separator(-ter) 5 when M finishes for sampling, g;
P is after water sample is carried out the bubbling end, the resulting pressure in sampling-separator(-ter) 5 and the separator(-ter) 8, MPa;
P
0＝0.1013MPa；
N is V, M, P and P
0Conversion constant.
From above-mentioned formula (1) as can be seen, because the change of phase separator structure of the present invention and principle of work, make sampling-separator(-ter) 5 have the function of gathering water sample and segregation, V in formula and M, be respectively the volume of sampling-separator(-ter) 5 and the quality of gathering water sample, therefore, formula (1) can be exchanged into following formula:
In the formula, C
gBe contained gas concentration in the water sample under the status of criterion, cm
3Gas/g water;
C is that gas chromatographicanalyzer records contained gas concentration percent by volume in the interior water sample of gaseous sample to be measured;
V is air phase volume (volume of sampling-separator(-ter) 5, cm
3);
The quality of water in the sampling-separator(-ter) 5 when M finishes for sampling, g;
Watery density when ρ finishes for sampling in the sampling-separator(-ter) 5, g/cm
3, ρ=1g/cm generally
3
P is after water sample is carried out the bubbling end, the resulting pressure in sampling-separator(-ter) 5 and the separator(-ter) 8, MPa;
P
0＝0.1013MPa；
C in the formula (2)
gWatery density when only finishing with sampling in the sampling-separator(-ter) 5 is relevant, irrelevant with the volume of gas sample bottle 2, sampling-separator(-ter) 5 and separator(-ter) 8, therefore do not need the volume of sampling-separator(-ter) 5, separator(-ter) 8 and gas sampling jar 2 is accurately demarcated, avoid the error that volumetric calibration brought, thereby reduced the difficulty of processing of sampling container.
Adopt phase separator of the present invention that dissolved gases in the water sample is separated, segregation vacuum tightness is 5～10kPa, and the efficient of once emanating can be stablized and remains on 〉=99% (efficient of once emanating demonstration test data see Table 1), and only be 0.5 hour its sample time.
The present invention is particularly useful for the manual sampling of dissolved gas in the PWR nuclear power plant one circuit system cooling medium.
