Background technology
Reactor is the nucleus equipment in chemical process, influential effect of the reactor to mass transfer between each reaction mass
It is huge, it is the key factor for influenceing product quality and production efficiency.When being chemically reacted in liquid phase, it is commonly present parallel or connects
String competitive reaction, the intermediate product or end-product of reaction can further react with the component of certain in raw material, make reaction raw materials
Between initial mixing effect greatly influence the speed of reaction, selectivity and yield, and the design of influence production process simultaneously,
Energy consumption and production cost.So designing efficient Liquid-liquid mixing equipment, the initial quick mixing between liquid-liquid is realized, for improving
Reaction rate, reduce side reaction, reduce energy consumption and production costs it is significant.
The mechanism of Liquid-liquid mixing mainly has Laminar flow mixing and turbulent closure scheme.In industrial production, in order to promote differential responses thing
And being sufficiently mixed between catalyst, often utilizing the equipment of turbulent closure scheme principle, use mainly has stirred autoclave, jet to spray
Blender, impinging streams mixer, static mixer etc..Wherein, the most frequently used reactor is the batch tank with agitating device
Reactor, but the shortcoming of this reactor is that internal back-mixing is uneven, and stirring efficiency is not high, is not suitable for continuous operation.
Industrial to be often related to liquid-liquid heterogeneous phase chemical reaction, whether the effect of reaction depends between heterogeneous liquid
Enough effectively dispersions and mixing.Carried out as catalyst especially with the acid of the inorganic liquids such as the concentrated sulfuric acid, phosphoric acid or ionic liquid
Alkylation reaction of arene, catalyst plays decisive with yield and selectivity that whether reaction mass can well mix to reacting
Effect.In order to strengthen the mass-and heat-transfer effect of heterogeneous storeroom, impact flow reactor and its expanding unit arise at the historic moment.So
And, most impact flow reactors are that propeller arrangement is set in guide shell, the fluid of different directions is accelerated to collision, but
Because the motor shaft of propeller is cantilever design, cause unstable and easy damaged in plant running, shorten the use longevity of reactor
Life；Another settling mode is to make liquid to being clashed into injection using circulating pump and one or more groups of nozzles, although enhance mixing
Effect and performance stability, but existing design can not realize mixing by different proportion between differential responses raw material, i.e., can not adjust
The mol ratio reacted between control reaction raw materials.Alkylated reaction sour for inorganic liquid or ionic liquid-catalyzed is, it is necessary to connect
There is the mol ratio between larger different material in tactile area, and needs larger catalyst concn, so could preferably improve anti-
The selectivity answered, reduces the generation of side reaction, and existing design is all difficult to solve this problem.
The content of the invention
The purpose of this utility model is to provide for a kind of percussion flow mixing reactor for solving the above problems, structure design
Rationally, using reliability, can be fully contacted heterogeneous liquid liquid material, improve reaction efficiency, and can adjust reaction mass
Proportioning, effectively improves the yield and selectivity of reaction, reduces the generation of side reaction.
The technical solution of the utility model is：
A kind of percussion flow mixing reactor, including reactor, it is characterised in that：The reactor is in spheroid shape, and instead
The major axis two ends of plane and plane-parallel where the major axis of kettle, the reactor are answered to insert Venturi tube, two literary mounds respectively
In pipe extend to reactor center and the inner is respectively fixed with nozzle, two spouts of nozzle are relative, two Venturi tubes it is outer
End is connected to feed pump using feeding line, and branch pipe, the branch tube end are respectively equipped with two side walls of Venturi tube
Reactor outside is drawn, the outside of the reactor is provided with the chuck for being passed through refrigerant or heating agent, and the top of the chuck is provided with folder
Set outlet, the bottom of the chuck is provided with JI, and the bottom of the reactor is provided with reaction solution outlet.
The beneficial effects of the utility model are：
1st, reactor introduces reaction masses by two Venturi tubes, then is sprayed to hitting material high-speed by nozzle
Hit, increased liquid-liquid contact area, catalyst and other components are added in reaction system by the way that branch pipe is controllable, also simultaneously
Participate in the injection of liquid liquid to clash, secondary collision occur with the inwall of reactor again after liquid at high speed head-on collision, dispersion effect is collided in enhancing,
Reaction efficiency, reaction yield and reaction selectivity are significantly improved, the generation of side reaction is reduced.
2nd, chuck is used for the cooling and heating of reaction mass, and effective controlling reaction temperature is in zone of reasonableness, it is ensured that product matter
Amount.
