Art effect.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is illustrated.
Referring to FIG. 1, a kind of semi continuous automatic sampling system, comprising: circulation three way ball valve 4, blowback main road needle-valve 3,
Quantitative pot 1, outlet three-way ball valve 7, nitrogen purging device and sampler, connection relationship therein are as follows: the circulation three way ball
One end of valve 4 is connected with liquor inlet pipeline, the another both ends of the circulation three way ball valve 4 respectively with the quantitative pot 1 and take
Sampling device connection；The other end of the quantitative pot 1 and the outlet three-way ball valve 7 connection；Another the two of the outlet three-way ball valve 7
Pipeline of answering back respectively with the nitrogen purging device and feed liquid is held to connect；One end of the blowback main road needle-valve 3 and feed liquid into
Mouth pipeline connection, as shown, the pipeline that blowback main road needle-valve 3 is connected with liquor inlet is also connected to circulation three way ball valve 4, institute
The other end and the quantitative pot 1 for stating blowback main road needle-valve 3 connect；1 volume of quantitative pot can be determined according to actual needs
Set up meter.
In addition, the sampler includes sampling needle-valve 5 and sampling bottle 2, the both ends of the sampling needle-valve 5 are separately connected institute
State circulation three way ball valve 4 and sampling bottle 2.
In addition, the nitrogen purging device includes nitrogen pipeline check valve 8 and nitrogen needle-valve 9, the nitrogen pipeline is unidirectional
The both ends of valve 8 are separately connected the outlet three-way ball valve 7 and the nitrogen needle-valve 9, the other end connection of the nitrogen needle-valve 9
Nitrogen inlet (abbreviation N2 entrance) pipeline.Extra feed liquid can be blown into using nitrogen purging by system and realize zero-emission target.In addition,
It further include quantitative pot liquidometer 6, the quantitative pot liquidometer 6 connects the quantitative pot 1.As shown, quantitative pot liquidometer 6
Two connecting tubes are connected to up and down at two of quantitative pot 1, and the effect of quantitative pot liquidometer 6 is for showing in quantitative pot 1
Amount of fluid.
The pipe diameter determing of the application is different size caliber, and the sampling circulation line caliber of circulation three way ball valve 4 is 1/8 ",
Blowback major loop caliber be 1/2 ", nitrogen inlet line pipe diameter be 1/4 ", feed liquid answer back pipeline caliber be 1/4 ", sampling caliber be
1/8 ", when system sample introduction, uses small-bore circulation line to reach continuous sampling purpose to extend sample injection time；Using big when sampling
Bore blowback main line and small-bore sampling line are to realize the purpose of fast sampling；When sampling, sampling and blowback are opened simultaneously
Pipeline makes sample distribute sampling amount automatically according to pipe diameter size, therefore even if sampling medium has the non-uniform phenomenons such as layering also
The true representations of sample are not influenced.
Process flow is said below:
Feed liquid introduces sampling system liquor inlet by medium pipeline, then passes through circulation three way ball valve 4 and is delivered to quantitatively
Tank 1, by being sent after quantitative pot 1 to outlet three-way ball valve 7, by the feed liquid for being delivered to media outlet after outlet three-way ball valve 7
It answers back pipeline.Blowback nitrogen enters sampling system by nitrogen inlet, and medium is by nitrogen blowback by anti-in subsequent quantitative pot 1
It blows main road needle-valve 3 and sends medium pipeline back to, can also be sent by circulation three way ball valve 4 and sampling needle-valve 5 in simultaneous quantitative tank 1 to taking
In sample bottle 2.
There are also the technological principles of the application:
Since sampling circulation line caliber is 1/8 ", quantitative tank volume can be set according to sampling interval time (being assumed to be 1h)
(pressing 1.5m/s flow relocity calculation, about 7.6L).Since practical sampling does not need so many sample, need to carry out when sampling
It shunts, passes through nitrogen blowback when sampling.Blowback major loop caliber is 1/2 ", and sampling caliber is 1/8 ", can be calculated according to caliber
Distribution ratio of liquid flow is VInstead: VSample=21.5:1, therefore final sampling amount is about that (sampling valve is needle-valve to 338ml, and sampling amount can also basis
Actual needs adjustment sampling valve position).
The application method of the application sampling system:
(1) continuous sample introduction: switching circulation three way ball valve 4 (circulating valve position) and outlet 7 (circulating valve of three-way ball valve before sampling
Position), since caliber needs long period (1 volume of quantitative pot is set according to sampling interval time) full of quantitative pot 1 compared with small sample,
Circulation three way ball valve 4 (complete to close valve position) and outlet three-way ball valve 7 (complete to close valve position) are closed after sample is full of quantitative pot 1.
(2) blowback sample: successively open nitrogen needle-valve 9, blowback main road needle-valve 3, circulation three way ball valve 4 (sampling valve position) and
It exports three-way ball valve 7 (back-flushing valve position), after emptying to quantitative pot 1, closes above-mentioned valve, complete sampling, remove sampling bottle 2.
The utility model improves existing sampling system, and therefore, compared with prior art, the utility model has certainly
The advantages of dynamic continuous sampling, true representations, good reliability and long service life.In addition, working as the qualitative of certain chemical products
When can have larger fluctuation, the continuous sampling that can use this system obtains more true representational sample；Can also will be
Automatic sampling can be achieved after carrying out automatic improving in related accessory in system.
Disclosed above is only several specific embodiments of the utility model, but the utility model is not limited to this, is appointed
What what those skilled in the art can think variation, should all fall within the protection scope of the present utility model.
