In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, recycling sulfur hexafluoride first passes through tertiary effluent eluting column, three-level lye eluting column, de-watering apparatus
Using the adsorption tower that specific adsorbent is housed after processing, i.e., hydrolyzable in recycling sulfur hexafluoride gas or alkaline hydrolysis impurity are decomposed
For SO2, HF etc., SO2, HF etc. be dissolved in water, in lye, since solubility is low in water, lye for sulfur hexafluoride, to reach
Except the purpose of the impurity such as a large amount of fluorination sulfonyls, fluorination thionyl, thionyl tetrafluoro.Again by being equipped with after washing, alkali cleaning
The adsorption tower of specific adsorbent, the water contained in removal sulfur hexafluoride gas respectively, minor amount of water, HF and absorption fluorination sulfonyl,
It is fluorinated thionyl, thionyl tetrafluoro etc., so that thoroughly recycling purification sulfur hexafluoride gas, then passes through compressor for sulfur hexafluoride
It is filled into container.
Following reaction: bifluoride sulphur, sulfur tetrafluoride, difluoro in alkaline cleaning procedure occurs in water elution, lye lessivation
Change the objectionable impurities such as two sulphur, thionyl fiuoride, thionyl tetrafluoro, fluorine, hydrogen fluoride, can be eluted and be removed by potassium hydroxide aqueous solution
It goes, reaction equation is as follows:
2SF2 + H2O = SOF2 + 2HF + S
SF4 + H2O = SOF2 + 2HF
2S2F2 + H2O = SOF2 + 2HF + 3S
SOF4 + H2O = SO2F2 + 2HF
SOF2 + H2O = SO2 + 2HF
2F2 + 2H2O = O2 + 4HF
SO2 + 2KOH = K2SO3 + H2O
HF + KOH = KF + H2O
The moisture and micro objectionable impurities in sulfur hexafluoride are recycled, such as ten fluorine one aoxidize two sulphur, sulfonyl difluoro, fluorination
Hydrogen etc. can effectively be adsorbed by solid absorbents such as silica gel, aluminium glue, F-03, so passing through the processes such as washing, alkali cleaning, dry absorption
Above-mentioned impurity can be removed, qualified sulfur hexafluoride is obtained.
In conclusion passing through the processes such as washing, alkali cleaning, dry absorption by means of the above-mentioned technical proposal of the utility model
The objectionable impurities such as fluorination sulfonyl, fluorination thionyl, the thionyl tetrafluoro in sulfur hexafluoride can be removed, the lithium of qualification is obtained
Sulphur.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
