Description

A kind of difluoroethane reactor with stirring
Technical field
The utility model relates to a kind of difluoroethane reactor with stirring, and it is applicable to the field of acetylene and hydrogen fluoride addition reaction production preparation C2H4F2 C2H4F2 cooling agent.
Background technology
Utilizing acetylene and hydrogen fluoride that addition reaction production C2H4F2 C2H4F2 product takes place under the effect of catalyzer is the C2H4F2 C2H4F2 synthetic route that generally adopts at present.Because the singularity such as inflammable, explosive of acetylene and the severe corrosive of hydrogen fluoride and catalyzer, difluoroethane reactor is the traditional technology that domestic colleague mostly adopts gas-liquid phase bubbling.Because mass transfer and heat transfer are undesirable, for guaranteeing acetylene enough reaction times and lower temperature of reaction are arranged, reactor volume is huge; Simultaneously, owing to do not stir, form local superheating easily, the acetylene autohemagglutination generates a large amount of oligopolymer, not only reduce activity of such catalysts, shorten the reaction one way cycle, and because oligopolymer can stop up the discharge outlet of spent catalyst, thereby in order to reduce the viscosity of discharge, guarantee the smooth discharging of spent catalyst, the hydrogen fluoride that have to keep higher concentration discharges with spent catalyst, causes wastage of material, contaminate environment.
Summary of the invention
The utility model provides a kind of difluoroethane reactor with stirring, and it not only can improve throughput and cut down the consumption of raw materials, but also helps the safety dumping of catalyzer.
The utility model has adopted following technical scheme to be: a kind of difluoroethane reactor with stirring, it comprises reaction vessel, be provided with opening for feed I in the upper end of reaction vessel, opening for feed II and product delivery port, lower end at reaction vessel is provided with waste outlet, outside surface at reaction vessel is with cooling jacket and heating jacket, in reaction vessel, be provided with two groups of spiral coil cooling tubes, the lower end of spiral coil cooling tube is provided with entrance of cooling water I, the upper end of spiral coil cooling tube is provided with cooling water outlet I, be provided with entrance of cooling water II in the bottom of cooling jacket, hot water inlet I and hot water outlet I, at the top of cooling jacket cooling water outlet II, the center that it is characterized in that described reaction vessel inner chamber is provided with whipping appts, whipping appts comprises drive unit and stir shaft, drive unit and stir shaft are drive state, be provided with stirring rake on stir shaft, drive unit drives stir shaft and rotates, and stir shaft drives stirring rake and rotates.
Dead-tight magnetic driving equipment that Porcelain Jar was formed inside and outside described drive unit was served as reasons.Described stirring rake is magnetic force driving, and its blade is pusher blade.Stirring rake (16) is one or more layers stirring rake.
The utlity model has following beneficial effect: the utility model increases whipping appts in chuck or inner coil pipe difluoroethane reactor, not only can prevent to form local superheating, mass transfer, heat transfer are evenly, avoid the acetylene autohemagglutination to generate a large amount of oligopolymer, prolong activity of such catalysts, improve the reaction one way cycle; And can avoid oligomerization of acetylene thing deposition to stop up the discharge outlet of spent catalyst; Also can improve simultaneously the flowability of discharge, guarantee the smooth discharging of spent catalyst, thereby the hydrogen fluoride that reduces higher concentration discharges with spent catalyst, economizes in raw materials, and reduces environmental pollution.The stirring rake of whipping appts of the present utility model is magnetic force driving, and paddle is pusher blade, so blade has self-suction function, can participate in reaction for the acetylene gas of reaction again like this.The utility model adopts the structure formation that stirs with dead-tight magnetic force driving, magnetic driving equipment is a transmission mechanism of being made up of inside and outside Porcelain Jar, stir shaft is not contacted with air, do not have conventional stir shaft and the sealing between the reactor body yet, thereby leaking of high-risk materials such as acetylene and hydrogen fluoride just can not occur avoiding yet.
