Description
Technical field
The present invention relates to the mixing arrangement in chemical industry, specifically a kind of combined type stratiform fluid partition mixing arrangement and application thereof.
Background technology
Mixing is two or more materials to be disperseed mutually and the unit operations that reaches certain uniformity coefficient, is the step that first all chemical reactions will complete, and can be divided into micromixing and mix two classes with microcosmic.Micromixing refers to the mixing of large scale, describes the process of circulation, dispersion and the mixing of material in whole reactor; Conventionally adopt the equipment such as agitator and electromagnetic shaker to complete, as the various agitators of anchor formula, frame, combined type etc. in ultrasonic oscillator, magnetic stirring apparatus and main equipment.Microcosmic mixes and refers to that the turbulent flow of small scale becomes micelle by fluid breakup, finally by molecular diffusion, makes system reach the uniform process of molecular scale.Molecular diffusion is to realize the crucial governing factor that microcosmic mixes.
In the industrial process such as fine chemistry industry, polymerization process, biochemical industry, pharmaceutical engineering, usually relate to some complexity, chemical reaction or physical process fast, it is very important that strengthening molecular diffusion realizes that good microcosmic mixes.According to Fick's law, be directly proportional the diffusion time of material to diffusion length, and therefore reducing diffusion length can shorten diffusion time significantly, thereby reaches the object of rapid mixing.
The mixed reactor of this strengthening material diffusion is not strange, and popular micro-reactor apparatus is exactly based on this at present.K.Jahnisch, V.Hessel. wait the multiple mixing arrangement form of microreactor of introducing in < < Chemistry in Microstructured Reactors > >, the micro-mixer that utilizes shunt method to mix as Bessoth F G etc., the Z-shaped micro-control continuous mixing device of Mengeaud V etc., the micro-fluidic blender of " Christmas tree " shape of dertiger S K W etc., the Chaotic Micro Mixer of the report such as stroock A D etc.; But the mixed form of these materials is to mix with droplet-like mostly, to install more complicatedly, machining accuracy is higher.
US4.239.732 introduces a kind of mixing head, can be used for mixing and the dispersion of two or more sets materials.This equipment is that injecting type mixes, and can be used for high-viscosity material.
US4.735.359 introduces a kind of apparatus for combining liquids, and this mixing of materials form is that stratiform is mixed, and utilizes centrifugal device that material is to thin layer state and sends, and thickness of thin layer is about 0.1 millimeter, the shortlyest at 0.1 millisecond, can complete abundant mixing.This device is fixed, and the combined amount of unit interval is certain, therefore in application, has certain limitation; Machining is more complicated simultaneously, and plant maintenance requires high.
Lamelliform mixes simpler, applied range.As far back as 1963, the scientist Yu B.Kletenik of the former Soviet Union published an article on < < Soviet Union physical chemistry magazine > >, describes a kind of multilayer shape mixing arrangement in detail.This device has very large reference to research afterwards.
CN101234324 has introduced a kind of stratiform blender equally, this blender by upper and lower chamber, be embedded in a whole housing or each other close-connected shell part assembly overlap joint form, thereby this device obviously exists processing difficulties, adjustable degree is little, and outlet is difficult for and the shortcoming such as other devices are connected.
Have at present the integrated device of being of document announcement, machining accuracy is high, and condition of work is harsh, and maintenance cost is higher, is not easy to maintenance, if occur, stops up, and is difficult to process, so generally can only be for not producing the reaction of the aqueous material of obstruction.
