CN203440075U discloses a kind of device of preparing sulfur hexafluoride gas, comprises molten sulphur device and reactor, and molten sulphur device communicates by Molten sulphur outlet conduit with reactor.
In current sulfur hexafluoride industrial production, a reactor only has a reaction compartment, has following shortcoming:
1) reactor quantity is many, and it is more loaded down with trivial details that the sulphur of reactor such as adds at the operation;
2) system leak source is corresponding more, fluorine gas low conversion rate, and in thick gas, foreign matter content is also many;
3) in reasons such as electrolyzer maintenance, cause under the temporary transient dead status of reactor, need heating to maintain sulphur in molten state, product energy consumption is high.
Summary of the invention
First technical problem that the present invention will solve is to provide a kind of multiple-chamber reactor of preparing sulfur hexafluoride.
Second technical problem that the present invention will solve is to provide a kind of using method of this multiple-chamber reactor.
The multiple-chamber reactor of preparing sulfur hexafluoride of the present invention, be included as charging zone and reaction zone, its reaction zone is divided at least two reaction chambers by dividing plate, and each reaction chamber is a unit that fluorine gas reacts with liquid-state sulfur, between dividing plate and multiple-chamber reactor bottom, leaves passage.
The detailed technical scheme of the present invention is: a kind of multiple-chamber reactor of preparing sulfur hexafluoride, be included as charging zone and reaction zone, reaction zone is divided into upper and lower two portions, bottom is liquid-phase chamber, top is divided at least two reaction chambers by dividing plate, between dividing plate and multiple-chamber reactor bottom, leave passage, each reaction chamber is established fluorine gas import and sulfur hexafluoride outlet, charging zone communicates with each reaction chamber with the passage between multiple-chamber reactor bottom by dividing plate, multiple-chamber reactor top is provided with temperature regulating device, and multiple-chamber reactor bottom is provided with sulphur well heater.Its material is soft steel, stainless steel, nickel or Monel metal etc.
The sulphur well heater of described multiple-chamber reactor bottom setting can be electric heater, for sulphur heating, sulphur is heated to fusing point more than 120 ℃, becomes molten state; Multiple-chamber reactor top is provided with cooling water jecket, the heat of fluorine gas and the generation of sulfur reaction process is shifted, and be provided with reaction chamber temperature point for measuring temperature on reactor top.
According to producing or maintenance needs, can close or open wherein arbitrary or several reaction chamber.
The use procedure that the present invention prepares the multiple-chamber reactor of sulfur hexafluoride is:
Solid sulphur joins charging zone C by sulphur charging opening 11, and by sulphur well heater 19, by solid sulphur heat fused, temperature is controlled at 120～180 ℃, and optimum temps is at 125～140 ℃, and the liquid-state sulfur of melting is distributed in the B of liquid-phase chamber region; Fluorine gas is parallel to liquid phase sulphur metal line 20 by fluorine gas import 12 and enters in reaction chamber a-quadrant, by temperature-measuring casing 13 thermometrics, sulphur and fluorine gas carry out chemical reaction, in cooling water jecket 18, pass into water coolant simultaneously, multiple-chamber reactor is carried out to temperature control, and the sulfur hexafluoride of generation enters into hypomere operation from sulfur hexafluoride outlet 14.In reaction process, according to the height of liquid level, sulphur is added in charging zone in good time.
The present invention is that during sulfur hexafluoride is produced, a conventional reactor only has a reaction compartment, an and corresponding liquid Space of reaction compartment, change a reactor into and have a plurality of reaction compartments, and the corresponding liquid Space of a plurality of reaction compartments, solved in sulfur hexafluoride industrial production and prepared the problems such as sulfur hexafluoride reactor quantity is many, reduced the energy consumption of sulfur hexafluoride.
The present invention joins together to form a whole liquid-phase chamber by Molten sulphur by the liquid phase part of reaction zone, has reduced work fussy degree, and technique is easy to control.Simultaneously, because a plurality of reaction chambers are connected, make the volume of liquid-phase chamber relatively large, when system pressure fluctuation is larger, the fluctuation range of sulphur liquid level greatly reduces than the fluctuation range of the conventional single reaction compartment of single reactor, reduce Molten sulphur and overflowed in SF6 outlet conduit, caused the probability of sulphur frozen plug pipeline, reduced the phenomenon that reactor outlet that single chamber reactor causes stops up.
When the single chamber reactor of prior art is temporarily stopped using, in order to keep sulfur melting state, need to heat sulphur and maintain the above temperature of fusing point, will to sulphur, heat in advance the electric energy that need consumption is a large amount of while again enabling reactor.And the liquid phase of multiple-chamber reactor communicates, even if one of them even a plurality of reaction chamber is stopped using, because the heat release of fluorine, reaction of Salmon-Saxl is larger, in reaction chamber in normal use, the reaction heat of fluorine, reaction of Salmon-Saxl will make sulphur temperature in molten state, or by regulating the flow velocity of temperature lowering water just can make sulphur keep molten state, without sulphur heater is heated.Like this, multiple-chamber reactor can make sulphur always in molten state, heats the energy consumption of sulphur while having avoided reactor again to drive after parking because maintenance or other reason cause, and has greatly reduced production cost; Can improve simultaneously fluorine gas transformation efficiency, reduced the foreign matter content in thick gas.
