The sampling device comprises a sampling can arranged on the lower end of the storage can; the upper end of the sampling can is connected with the lower end of the storage can through a connecting pipeline; a control valve is arranged on the connecting pipeline; the top of the sampling can is provided with an air inlet pipeline connected with nitrogen; an air inlet control valve is arranged on the air inlet pipeline; the bottom of the sampling can is provided with a circulating pipeline; the upper end of the circulating pipeline is connected with the storage can; a sampling port is arranged on the circulating pipeline; a sampling control valve is arranged in the sampling port; and a circulating control valve is arranged on the circulating pipeline. The sampling device has the advantages that the structure is skillful; the use is convenient; the sampling result can completely meet the requirements; no polyether polyatomic alcohol is wasted; and the sampling device is suitable for the sampling of the polyatomic alcohol and the sampling of various liquid matters in the storage can.
Description
Technical field
The present invention relates to a kind of sampler, the sampler of polyether glycol in specifically a kind of hold-up tank.
Background technology
Usually polyether glycol leaves in the hold-up tank, for the polyether glycol in the hold-up tank is carried out sample analysis, at present the method that adopts is directly in the hold-up tank bottom sampling pipe to be set and to control by valve, open valve when needing sampling, polyether glycol in the hold-up tank will flow out from pipeline, finish sampling, the shortcoming of this sampling method is: because there is longer part the front portion of sampling pipe, for guaranteeing that sampling accurately, there is not impurity in the polyether glycol of guaranteeing to take a sample, obtained sample could be representative after must emitting the polyether glycol of some, the more polyether glycol that flows out before the sampling has influence on quality and just can only become waste product or substandard products owing to contacting with air like this, causes waste; If reduce the polyether glycol discharge capacity for saving, can cause the sampling result out of true again, there is not representativeness.Therefore, existing this sampling mode can not meet the demands.
Summary of the invention
In order to overcome the problem that existing polyether glycol sampling mode exists, the sampler that the purpose of this invention is to provide polyether glycol in a kind of hold-up tank, this apparatus structure is ingenious, easy to use, not only sampling result can meet the requirements fully, and can not cause the waste of polyether glycol, the present invention is not only applicable to the polyether glycol sampling, and is applicable to the sampling of fluent meterial in the various hold-up tanks.
The objective of the invention is to be achieved through the following technical solutions:
The sampler of polyether glycol in a kind of hold-up tank, it is characterized in that: this device comprises the sampling jar that is arranged on the hold-up tank lower end, the upper end of sampling jar is connected with the lower end of hold-up tank by connecting tube, is provided with operation valve on connecting tube; Be provided with the admission line that connects nitrogen at the sampling jar top, on admission line, be provided with air intake control valve; Be provided with circulating line in the sampling jar bottom; The circulating line upper end is connected with hold-up tank; On circulating line, be provided with sample tap, be provided with the sampling operation valve at the sample tap place; On circulating line, establish circulation control valve.
Among the present invention, the circulating line upper end is connected with the middle part of hold-up tank.
The present invention relies on nitrogen gas pressure, the polyether glycol that adopts the circulating line structure to emit before sampling flow back into again to be deposited in the jar, avoided causing the waste of polyether glycol, and owing to can not cause waste, can circulate several times more, free from foreign meter in the polyether glycol of guaranteeing to take a sample, guarantee the accurate of sampling result, the best is effective.Compared with prior art, structure of the present invention is ingenious, easy to use, and not only sampling result is accurate, and can not cause the waste of polyether glycol.
The present invention is not only applicable to the polyether glycol sampling, and is applicable to the sampling of fluent meterial in the various hold-up tanks.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The sampler of polyether glycol is seen Fig. 1 in a kind of hold-up tank of the present invention, and this device comprises the sampling jar 2 that is arranged on hold-up tank 1 lower end, and the upper end of sampling jar 2 is connected by the lower end of connecting tube with hold-up tank 1, is provided with operation valve 3 on connecting tube; Be provided with the admission line B that connects nitrogen at sampling jar 2 tops, on admission line B, be provided with air intake control valve 6; Be provided with circulating line 7 in sampling jar 2 bottoms; Circulating line 7 upper ends are connected with the middle part of hold-up tank 1; On circulating line 7, be provided with sample tap A, be provided with sampling operation valve 4 at sample tap A place; On circulating line 7, establish circulation control valve 5.
During sampling, at first open operation valve 3 and circulation control valve 5, close sampling operation valve 4 and air intake control valve 6, the polyether glycol in the hold-up tank 1 is flow in the sampling jar 2 from the lower end; Open air intake control valve 6 then, feed nitrogen, the polyether glycol in the sampling jar 2 is flow back in the hold-up tank 1 again by circulating line 7, finish the cleaning first time sampling pipe by nitrogen pressure by admission line B; So repeat for several times, till the polyether glycol that obtains from sample tap A meets the demands fully.Close circulation control valve 5 and operation valve 3, open sampling operation valve 4, take a sample.
Structure of the present invention is ingenious, easy to use, and not only sampling result is accurate, and can not cause the waste of polyether glycol.
The present invention is not only applicable to the polyether glycol sampling, and is applicable to the sampling of fluent meterial in the various hold-up tanks.
