Description
Technical field
The use of the new type and organosilicon production field, and in particular to a kind of liquid chlorosilanes sampling system.
Background technology
The primary product of direct method organosilicon chlorosilane production is methylchlorosilane, since the material of methylchlorosilane is special
Property, Yi Yushui, air etc. occur vigorous reaction and generate corrosive gas hydrogen chloride and gel hydrolysis object so that are being to production
There are certain danger when system sampling, the sampling mode taken at present for the chlorosilane of facile hydrolysis and sampling system there is also
Diversification.
A kind of sampling system for methylchlorosilane production is described in CN204649472U, is characterized mainly in that methyl
Chlorosilane life process pipeline be equipped at least two sampled points and corresponding back flow of sample point, each sampled point with it is corresponding
It is equipped with cycles samples pipeline between back flow of sample point, and is equipped with sampling slip on each sample circulation line, all sampling slips
Manifold is accessed by respective switching valve group, sampling manifold is connected to the injection port of analytical instrument, this Patent design is excessively multiple
Miscellaneous, operation is loaded down with trivial details, and cost is higher.
A kind of liquid chlorosilane on-line period device, including sampling bottle, pipeline, triple valve are described in CN201555740U
And shut-off valve.At least one input port and a delivery outlet, input port end are connected with input unit, and delivery outlet end is connected with defeated
Go out device.The sampler, it is simple in structure, it is easy to operate, it is mainly used for chlorosilane component, the sampling that impurity content is analyzed
Process.The shortcomings that this patent, which is sampling line, does not have nitrogen to purge and protect system, after switching sampling bottle, in sampling line inner wall
Surplus material easily instill sampling bottle contaminated samples；Though sampling line is transparent pipe, validity period is short, not corrosion-resistant.
A kind of chlorosilane liquid produced sampling equipment is described in CN203405345U, pipeline is arranged as nitrogen inlet duct road point
At nitrogen protection pipeline and nitrogen sparge tube road.Nitrogen protection pipeline leads to nitrogen protecting cover, and nitrogen sparge tube road leads to medium respectively
Cooling device and medium entrance pipeline, media outlet pipeline and blowoff line lead to medium cooling device and medium probe tube respectively
Road, medium sampling line lead to nitrogen protecting cover through double needle seat sampler, and gas exhaust piping leads to nitrogen through double needle seat sampler to be protected
Shield.The pipeline arrangement of the sampling equipment ensures to select in whole operation process for the physics and chemical characteristic of chlorosilane material
With under state status, reducing the corrosion and pollution that chlorosilane is contacted with air as far as possible, it is ensured that equipment can pacify steadily in the long term
It entirely uses.The shortcomings that this patent is that design is complicated, and pipeline is longer, and loss of material is big, and double needle seat sampling is difficult, after nitrogen purging
Tail gas do not absorb, direct external emission pollution environment.
Currently, the chlorosilane sampling mode that organic silicon monomer producer takes mostly is to open the chlorosilane being mounted on pipeline
Sampling valve first releases a certain amount of chlorosilane, cleans sampling line, then quickly sampling bottle is positioned under sampling nozzle,
It is discharged in sampling bottle.Although whole process is simple, in sampling process chlorosilane always with atmosphere, first, replacement piping
Chlorosilane be lost in waste cause equipment corrode and environmental pollution；Second is that material injection sampling bottle during just with air
Moisture reacts, and obtained sample cannot reflect the effect of system operation very well, therefore the analysis result of sample is also serious
It is affected.
