Description
Technical field
It the utility model is related to the sampler on chemical industry decompression distillation system fluid pipeline.
Background technology
Vacuum distillation is one of common chemical separation technology, is needed in vacuum distillation process constantly from overhead condensation liquid
The composition change of middle sampling monitoring cut, to judge distillation process and effect, since vacuum distillation is pumped vacuum systems,
More difficulty is sampled on overhead condensation liquid pipeline, if sampled at extraction storage tank, cannot meet the purpose monitored in real time, pin
Detection requirement to real time sample is, it is necessary to design a kind of sampler on vacuum pipe.
The content of the invention
The purpose of this utility model is aiming at disadvantages mentioned above, there is provided fluid sampling device in a kind of vacuum pipe, with up to
To the purpose of real time sample monitoring overhead fraction composition change.
What the technical solution of the utility model was realized in：Fluid sampling device in vacuum pipe, including feed pipe, take
Sample pipe, inlet valve, outlet valve, feed pipe, sample working area, vacuum transverse tube, it is characterized in that：It is horizontal that feed pipe connects corresponding vacuum
One end of pipeline, probe tube are connected with the vacuum horizontal pipe other end, are sample working area among vacuum horizontal pipe, sample working area
Both ends are inlet valve and outlet valve respectively, and inlet valve is connected with feed pipe with probe tube respectively with outlet valve, and the sample is temporary
Deposit and a blow-down pipe is provided with area, blow-down pipe is connected with the middle part of sample working area by blow valve.
Further say：The vacuum horizontal pipe is decompression distillation system fluid pipeline.
Further say：The sampler is stainless steel.
Further say：Feed pipe, probe tube, blow-down pipe and the vacuum horizontal pipe connection mode is welding, flange
The modes such as connection, threaded connection.
The beneficial effects of the utility model are：Fluid sampling device in such vacuum pipe, cleverly makes sampler
Keep apart with destilling tower, when use first opens inlet valve, closes blow valve and outlet valve, will be vacuumized in sampler, just
Liquid is entered in sample working area, be then shut off inlet valve, operation afterwards is just unrelated with destilling tower, opens blow valve,
Into gas, outlet valve is finally opened, liquid is flowed out from probe tube, has thus achieveed the purpose that sampling, has operation letter
The advantages of single.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein：1 is feed pipe, and 2 be inlet valve, and 3 be blow-down pipe, and 4 be blow valve, and 5 be probe tube, and 6 be outlet valve, and 7 are
Sample working area.
Embodiment
With reference to embodiment and attached drawing, the invention will be further described.
As shown in Figure 1, fluid sampling device in vacuum pipe, including feed pipe 1, inlet valve 2, blow-down pipe 3, blow valve 4,
Probe tube 5, outlet valve 6, sample working area 7.
Feed pipe connects one end of corresponding vacuum horizontal pipe, and probe tube is connected with the vacuum horizontal pipe other end, and vacuum is horizontal
Sample working area among pipeline, sample working area both ends are inlet valve and outlet valve respectively, inlet valve and outlet valve respectively and
Feed pipe is connected with probe tube, and a blow-down pipe, blow-down pipe and sample working area middle part are provided with the sample working area
Connected by blow valve.
In this way, during sampling, inlet valve is first opened, closing blow valve and outlet valve, system will first vacuumize in sampler,
Liquid enters in sample working area, is then shut off inlet valve, opens the blow valve of fluid sampling device, enters in sample working area
Air, finally opens outlet valve, and so under gas pressure, liquid is flowed out from probe tube, and sampling terminates, and closes blow valve and goes out
Expect valve, realize the purpose of this utility model.
Further speaking, the vacuum horizontal pipe is decompression distillation system fluid pipeline, can thus be made in destilling tower
Liquid flow rapidly into pipeline.
Further speaking, fluid sampling device is stainless steel in the vacuum pipe, has and is not easy the excellent of corrosion
Point.
Further speaking, the feed pipe, probe tube, blow-down pipe and vacuum horizontal pipe connection mode are welding, flange
The modes such as connection, threaded connection, have present apparatus connection fastening, steady advantage.
Architectural feature the foregoing is merely specific embodiment of the utility model, but the utility model is not limited to this,
Any those skilled in the art in the field of the utility model, all cover in the utility model by the change or modification made
In the scope of the claims.
