Description
Technical field
The utility model relates to a kind of membrane dispersion type micro-channel reactor, and the membrane module that is used for this membrane dispersion type micro-channel reactor.
Background technology
The particle of little, micro-nano structure such as metal and metal oxide nanoparticles, inorganic compound, organic compound and drug particles live in modern times every field; Like electronics, information, engineering, the energy, chemical industry, machinery and medical treatment etc.; All have a wide range of applications one of emerging especially point of economic increase.The method of little, the micro-nano structure material of preparation of various physics and chemistry and technology is developed and constantly development.Yet in technologies such as the traditional chemical reaction and the precipitation method; Need to utilize stir, ultrasonic and means such as injection and grinding mix and mass transfer; But these means are relatively poor on mass-transfer efficiency and effect; Can't prepare the emulsion droplet and the particle of size homogeneous, and particle diameter control difficulty is high, batch poor repeatability.
Micro passage reaction based on micro-processing technology; Can realize the accurate control of right micro liquid; The a series of unit operations of mixing, chemical reaction or the like is all carried out in accurate volume, can improve the homogeneity of micro emulsion and the particle of generation, but the microreactor that is based on micro-processing technology exist processing cost high with amplify difficult shortcoming; Can only be used for laboratory research at present, also can't be applied on a large scale in the actual generation.
Utilizing perforated membrane is a kind of novel reactor that grew up in recent years as the dispersive film reactor of decentralized medium; The fluid that promptly makes a side through microporous barrier is distributed in the liquid of film opposite side with equal forms of once high sizes finer droplet under the effect of pressure; Because fine drop has more bigger serface; Mass transfer is more abundant sooner with heat transfer when contacting with another, has improved the efficient and the homogeneity of chemical reaction, extraction and unit operations such as emulsification and granulate preparation greatly.Strengthen the microcosmic mass transport process, some relevant researchs have been arranged both at home and abroad.Chinese patent CN1605359 discloses a kind of dispersive film extractor, and this extractor utilizes film pipe or the flat sheet membrane of aperture for the 0.01-60 micron, and decentralized photo liquid is dispersed into small drop, increases mass transfer area, improves the effect of extraction.Chinese patent CN1318429 discloses the method that a kind of film dispersion method prepares ultra-fine grain; Also adopt the reactor of the type; The preparation barium sulfate particle; Sulfuric acid-butanol solution is crossed microporous barrier be dispersed into droplet, go out barium sulfate particle with the barium chloride solution prepared in reaction again, this patent only utilizes microporous barrier that the initial particle of drop is limited; But the mixed characteristic after the fluid contact (like the thickness of flow velocity, fluid layer etc.) is not controlled, therefore the particle diameter (average particulate diameter is 1 micron) bigger than normal of preparation.
Chinese patent CN101433815 discloses a kind of membrane dispersion type micro-channel reactor; Manage forming sleeves by in an outer tube and one, between inner and outer pipes, form the microchannel of annular, outer tube is provided with continuous phase import and outlet; Interior Guan Yiduan is provided with the import of decentralized photo; The other end is the film tubular construction that porous is arranged that tube wall is uniformly distributed with, and this device has increased the sectional area and the flow velocity that has increased continuous phase of microchannel effectively, has improved the treating capacity of single reactor and has guaranteed that stronger microcosmic mixes; This reactor is more suitable in the fast reaction of liquid liquid or liquid gas; But the inlet of this device continuous phase is positioned at a side, can cause the annular inside microchannels difference of flow velocity everywhere, causes the difference to porous membrane tube surface shear power; Finally have influence on the homogeneity of dispersant liquid drop, adopt this reactor to be difficult to obtain uniform emulsion droplet or particle.
The membrane emulsifier of CN201006421 and CN101683592 and the exploitation of Japanese SPG technology Co., Ltd passes through the SPG fenestra through emulsion under the effect of high pressure, form the emulsion droplet of uniform particle diameter.CN101683592 discloses a kind of many film pipe component film assemblies side by side, and the micropore of the decentralized photo filmed passing tube of film tube outside is distributed to the inside of pipe, in pipe under the shearing force effect of continuous phase liquid to the film pipe; Realization is with the separation of film; In continuous phase, form tiny one by one drop or emulsion droplet, the use of membrane module realizes industrial high-throughout requirement, but because various business-like film bores are thicker; And the preparation internal diameter receives cost and technology limitation less than the film pipe of 2mm; The film bore that uses at present more than 4mm, therefore uses the flow transmission equipment of identical power to carry continuous phase usually, and continuous phase is lower at the flow velocity in the film pipe; The shearing force that produces is less; Reduced the efficient of mass transfer, the emulsion droplet of preparation is big (usually more than micron) also, can't satisfy the littler nano-emulsion of preparation and nano particle and the requirement for preparing the high concentration product.To realize in this technology that continuous phase has higher shearing force at the film pipe internal surface, then need significantly improve the power of equipment,, increase equipment cost and energy consumption in the production as using more powerful pump.
Therefore, be necessary to develop a kind of raising emulsifying power, be easy to amplify the film emulsifier unit of energy-conservation suitable suitability for industrialized production.
