Description
Technical field
The present invention relates to a kind of synthesizer of Chemicals synthesizer, especially electric conductive polymer-polyaniline.
Background technology
At present, by electric conductive polymer is carried out a large amount of research, think that polyaniline is the electric conductive polymer of tool using value.Yet, in the commercial process of polyaniline, can run into many complicated technology difficult problems, mainly show the synthesizer seriously corroded, emulsifying power is low, generated time is long, reaction heat is big in the polymerization process, temperature rising excessive velocities, and titration time is long, combined coefficient is low etc., so the research and development of polyaniline also concentrate on the laboratory polymerization stage at present mostly.
What existing polyaniline synthesizer adopted usually is the batch reactor structure, reactor adopts materials such as stainless steel, cast copper or enamel to make, under the situation of sour environment, polyelectrolyte concentration and the high oxidation agent of complexity, reactor is seriously corroded not only, work-ing life is short, also has a strong impact on the purity of product.The stirring mechanism of tradition reactor adopts the mode of single-point stationary shaft, the mixing part of stirring mechanism bottom is easy to generate rocks, therefore its stirring velocity maximum is no more than 180 rev/mins, and the emulsifying process of polyaniline requires preferably 200～800 rev/mins of the stirring velocitys of reactor, therefore the emulsifying power of traditional reactor is low, can not satisfy the emulsifying process requirement of polyaniline.Though traditional reactor has adopted external cooling jacket to carry out heat exchange, because the ratio of its heat interchanging area and reactor reaction volume is usually less than 1, so its heat exchanger effectiveness is low, can not satisfy processing requirement.In addition, traditional reactor adopts the mode that directly drips liquid to its inner chamber, and rate of addition is slow, and emulsification times is long, particularly jumbo reactor, and this dropping mode has a strong impact on reaction process, makes the synthetic quality product not high or unqualified.Notification number is CN1432033, the day for announcing is on July 23rd, 2003, name is called in the Chinese invention patent of " method and apparatus of preparation polyaniline ", provide tubular reactor and oxygenant gatherer that a kind of heat transfer area and reaction volume ratio are 10～20/m, but this device can't amplify on a large scale, do not solve simultaneously the etching problem of equipment yet, therefore be difficult to be applied in synthetic production of industrialization of polyaniline yet.
Summary of the invention
The purpose of this invention is to provide a kind of synthesizer that is used for the polyaniline suitability for industrialized production, to solve existing polyaniline synthesizer seriously corroded, emulsifying power is low, and polymerization temperature is difficult for the technical problem of stable control.
For solving the problems of the technologies described above, a kind of synthesizer that is used for the polyaniline suitability for industrialized production of the present invention is made up of batch reactor and titration jar, batch reactor comprises loam cake, reaction tube and stirring mechanism, the mixing part of stirring mechanism is positioned at reaction tube, reaction tube is provided with cooling jacket outward, reactor and titration jar all adopt macromolecule resin material to make, be provided with spiral coil cooling tube in the reaction tube, at least two bearings of the part that the transmission rod of stirring mechanism stretches out loam cake by vertical distribution up and down are on support.
Because reactor and titration jar all adopt macromolecule resin material to make, so good corrosion resistance, in the work-ing life of having improved equipment, also avoided the influence that material purity is caused because of equipment corrosion simultaneously.In reaction tube, be provided with spiral coil cooling tube, remedied and depended merely on the deficiency that cooling jacket carries out heat exchange, improved the heat exchange area of whole device, heat conduction efficiency is greatly improved, make the polymerization temperature of polyaniline keep stable, and can be controlled in the optimum range of processing requirement polymerization temperature is stable.The transmission rod of stirring mechanism stretches out the part of loam cake and passes through at least two bearings on support, promptly adopt 2 axle fixed modes, make the stable drive of transmission rod, the mixing part that effectively prevents stirring mechanism shakes, thereby can improve stirring velocity, to shorten the reaction times, improve emulsifying power, improve the speed of mass transfer and heat transfer, the key condition that makes microemulsion form environment is met, and makes synthetic being achieved of industrialization of polyaniline.
As preference, the ratio of the surface-area of above-mentioned spiral coil cooling tube and reaction tube internal reaction volume is preferably 5～30/ meters, and the best is 8～15/ meters, makes the heat exchanger effectiveness of whole device reach best, it is stable that the polymerization temperature of polyaniline keeps, and the stable scope that is controlled at-27～75 ℃.
As another preference, the opening for feed of loam cake links to each other with the titration jar with the material pipe by atomizing nozzle, and the upper end of titration jar is provided with pressure lock and feed-pipe, and a side of titration jar is provided with liquidometer, is serially connected with volume pump on the material pipe.Carry out pumping by volume pump, and be the vaporific raw material that drips by atomizing nozzle in reaction tube, it is reinforced to finish spraying at regular time and quantity, thereby improves product quality, shortens titration time and churning time.Whole device can be equipped with a plurality of titration jars, and it is reinforced respectively multiple titration raw material to be finished spraying, avoids the phase mutual interference of stock yard, guarantees material purity.
