Description
Technical field
The utility model belongs to chemical industry equipment technology related fields, and in particular to a kind of safe sample acquisitions of organolithium solution
Device.
Background technique
Oxidation reaction can occur when encountering humid air for organolithium solution, and localized hyperthermia is caused even to be ignited solvent
Fire has biggish security risk, and samples taken is lost representativeness by air pollution, can not carry out accurately examining detection.
The present invention acquires representational sample using closed cycle, and guarantees the security performance of operating process.
Utility model content
The purpose of this utility model is that aiming at the shortcomings in the prior art, providing a kind of safe sample of organolithium solution and adopting
Acquisition means.
In order to realize the utility model, using following technical scheme: the safe sample acquisitions device of organolithium solution, including take
Sample pipe group, valve group, air compression pipeline purging device；The probe tube group includes main pipeline and branch sampling loop pipe, branch sampling
The side of main pipeline is arranged in loop pipe, and is connected to main pipeline；The valve group includes main line valve, bypass valve one, bypass valve
Two, sampling valve, main line valve are arranged on main pipeline, and bypass valve one, bypass valve two are separately positioned on branch sampling loop pipe,
Sampling valve is arranged between bypass valve one and bypass valve two；One end of the sampling valve is equipped with speed with sealing Bottle & Can connector；Institute
State one end of air compression pipeline purging device connection main pipeline.
Further, when the main line valve is opened, bypass valve one and bypass valve two remain turned-off simultaneously；Main line valve is closed
When, bypass valve one and bypass valve two are separately turned on.
Further, the purge gas of the air compression pipeline purging device probe tube group input is high pure nitrogen or argon gas.
The utility model has the advantages that (1) the utility model structure is simple, installation and debugging are convenient, and workable range is wider.
(2) the sample acquisitions device in the utility model can ensure the safety operated when acquiring organolithium solution, just
It is prompt, efficient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment: the safe sample acquisitions device of organolithium solution, including probe tube group, valve group, air compression pipeline purging device
