Embodiment
With reference to Fig. 1, the fluoridation chamber 4 that is made into one, its top connects visor 12, epicoele connects the inner cooling jacket 8 of suit in its inner chamber, suit sighting tube cooling water jecket 11 in the inner cooling jacket 8, sighting tube cooling water jecket 11 is connected and installed inhalent siphon 10 and sighting tube 9. is connected and installed temperature tube 7 on the midfeather chamber of fluoridation chamber 4, connect as one with the sulphur vaporizing chamber 3 of cavity of resorption, be connected and installed fluorine gas inlet tube 5 on the ectosome of fluoridation chamber 4 from top to bottom, sulfur melting tank 1 and vaporizing chamber inlet valve 2, the fluoridation chamber 4 that is assembled into one is by connection line 17 analyser 6 that is linked in sequence, washing tower 13, moisture eliminator 14, compressor 15, gas-holder 16 general assembly one and constituting.When using the technology of the present invention, according to working specification, join fluorine gas in the fluoridation chamber 4 of the technology of the present invention by fluorine gas inlet tube 5, add the sulphur fused solution by sulfur melting tank 1 and vaporizing chamber inlet valve 2 again, it is reacted in fluoridation chamber 4, and instrument 6 is analyzed by analysis, after washing tower 13, moisture eliminator 14 are handled, the compressed machine 15 of high-purity sulfur hexafluoride of normal operation preparation is pressed into gas-holder 16, export trade or standby.
The technology that adopts the fluorine gas and the vapor reaction method of sulphur to produce sulfur hexafluoride is heated to sulphur more than the boiling point (444.6 ℃), sulphur is become enter reactor behind the steam and fluorine reacts.In a single day sulphur contacts with fluorine is spontaneous combustion, and its flame temperature can reach more than 1650 ℃.The characteristics of this method are to reduce the generation of the subfluoride of sulphur.
When adopting sulphur and fluorine direct reaction, in order to suppress the generation of subfluoride, it is excessive slightly to make every effort to fluorine gas during reaction.In addition, reactor should be able in time be derived a large amount of reaction heat of emitting owing to rapid reaction, and sulphur and fluorine ratio is in accordance with regulations reacted.
