Such as: copper material is made, and separation net 4 can be one layer, or multilayer has preferably, two layers of separation net 4 can be selected
Body, the oil liquid in petroleum pipeline can be input in tank body 1 by the first connecting tube 2, and the oil liquid entered in tank body 1 will pass through
Gas-liquid separation is carried out after separation net 4 in tank body 1, the gas wherein separated in oil liquid can be examined by the first opening 11 by concentration
Device is surveyed to be detected, and liquid portion can then flow out tank body 1 by the second connecting tube 3, specifically, oil liquid passes through the first connection
Pipe 2 enters in tank body 1 touch separation net 4 after, oil gas flowing on the one hand can be made steady, eliminate turbulent flow phenomenon, another party
Face, additionally it is possible to which the separative efficiency for accelerating oil gas, when the band liquid gas in oil gas touches separation net 4, gas part can be worn
Net and mistake, and the liquid portion in oil gas can be converged on separation net 4 due to the blocking of separation net 4 and be formed drop, and then complete
At the centrifugation of gas-liquid, the accuracy of gas concentration detection of the present invention is improved.
The present invention also provides a kind of concentration detection methods, complete by the concentration detection apparatus in any of the above-described embodiment
At.
Fig. 6 is the flow chart for the concentration detection method that the present invention provides in fact, referring to FIG. 6, this method comprises:
S101: being connected to petroleum pipeline for the first connecting tube, enters the oil liquid in petroleum pipeline in the first cavity；
S102: after the intracorporal air discharge of the first chamber is clean, the detection port of concentration detector is inserted into first and is opened
The concentration of the gas separated from oil liquid is detected at mouthful.
A kind of concentration detection method is present embodiments provided, in the slave oil liquid in more accurate detection petroleum pipeline points
From gas concentration.
In the prior art, staff installs the oil liquid of the sample cock discharge of petroleum pipeline usually using sample bucket,
While obtaining oil liquid sample, concentration detector can be placed at the bung hole of sample bucket to detect by staff to be divided from oil liquid
From gas concentration, but due to outside air influence, will cause separated from oil liquid gas concentration detection inaccuracy
Problem.Compared with prior art, the present invention provides concentration detection method by implementing to concentration detection apparatus of the invention
And complete, since the first connecting tube of device can connect tank body and petroleum pipeline, after the oil liquid in petroleum pipeline enters tank body,
Gas in oil liquid will be separated from oil liquid, and tank body is discharged in second opening that passes through air in tank body gradually, so
Concentration detector is placed on to the second opening of tank body again afterwards, detects the intracorporal gas concentration separated from oil liquid of tank, by
In the not influence of outside air in tank body, and then it can guarantee the accuracy of the gas concentration separated from oil liquid detection.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
