Description
Technical field
The utility model relates to a kind of novel membrane reactor, thinking particularly integrated according to flow process and process intensification is developed, the outside circulation gas lift type membrane reactor of integrated cross flow film aerating system, axial aeration reinforcing film separating system, be used for relating to the reaction that contains gas-liquid biphase heterogeneous reaction and biological fermentation such as solid of gas-liquid, gas-liquid and separate, belong to chemical industry and biochemical industry equipment.
Background technology
Airlift reactor is the contact reacts device that is used for gas-liquid two-phase or gas-liquid-solid three-phase process.Generally be made up of two different pieces, only feed gas a part, vent portion is called and rises the gas parts, and another part is injecting gas not, is called to fall the liquid parts.Airlift reactor gas enters in the external phase with the form of bubble, and this external phase can be liquid or contains solid suspension.Because ventilation has produced the different fluid density difference with the two-part different gas holdups of stuffiness, this just makes the reactor inner fluid produce and circulates.Along with fluidic circulates, most of gas rises to the liquid phase surface and overflows, and the small part bubble is involved in downtake by liquid, again circulation downwards.Circulation can make all, and each obtains well blend mutually, and solid is suspended in liquid effectively, and it is good to distribute in whole reactor, obtains gas-liquid or the solid mass transfer effect of gas-liquid preferably, and airlift reactor belongs to strength stirring-type reactor.
The kind of airlift reactor is a lot, can be divided into internal circulation gas-lift type reactor and outer circulation airlift reactor two big classes by the flow circuit situation usually, but its variation is also more.The internal circulation gas-lift type reactor is generally a simple bubble tower, a built-in division plate is divided into riser and downtake two portions with tower, and other also has the airlift reactor of multistage center pipe, multicenter pipe airlift reactor, Multi-Tube Airlift Loop Reactor etc.The riser of outer circulation airlift reactor separates fully with downtake, and by connecting respectively by two place's horizontal components at the bottom of the cat head tower, enter the interior gas injection of reactor to air-lift tube, because the injection kinetic energy of gas and riser inner fluid density reduce, force the riser fluid upwards, downtake is done well-regulated circulating downwards.Thereby form good mixing and condition.The internal circulation gas-lift type reactor has gas-liquid mass transfer preferably, and the riser gas holdup is much higher than the gas holdup of downtake.Compare with interior circulation airlift reactor, outer circulation airlift reactor flow rule, resistance is little, has the dead angle hardly, simultaneously, apparent liquid velocity is bigger, turbulent flow and gas-liquid mass transfer also increase, and heat transfer property also is better than the internal circulation gas-lift type reactor, and higher cycle rate is arranged, in addition, the also more easily degassing of outer circulation airlift reactor.
Compare with other reactors, that airlift reactor has is simple in structure, shearing force is low, air feed efficient height, effectively the interface contact area is big, fluid effect is splendid, each all has the clear and definite residence time and caloic transfer rate advantages of higher mutually.
Yet the mixing time of existing airlift reactor is generally greater than the mixing time of bubble tower, and is not ideal enough especially for the highly viscous liquid effect, mainly is that the same mixture contact is relatively poor; By contrast, the aeration-agitation reactor relies on mechanical agitation to help to disperse gas, can adapt to the high viscosity liquid operation.In recent years, can effectively address this problem by mechanical stirring being introduced the gas lift reactor, but churned mechanically introducing will be lost the intrinsic advantage of a lot of air lift types again, as churned mechanically introducing improved airlift reactor energy consumption, increased the internal motion parts, many biochemical reaction systems can't be carried out; Waste of energy is inhomogeneous etc.
Have many high consumption solid/liquid/gas reactions in chemical industry and biological fermentation field, though in traditional reactor by supercharging with improve aeration rate and can partly address this problem, but supercharging causes other gas solubilities to increase, as sour gas CO during the fermentation
2The increase of meltage will cause the acute variation of system environment.The simple raising aeration rate that relies on then can cause the increase of flow stream velocity in the airlift reactor and the raising of running cost.
In addition, exist different step of reaction in many chemical reactions or biological fermentation process, each stage is different with the requirement of air flow to mixing.But existing airlift reactor mixes and ventilation is a coupled problem, and the constant then troubled water of the condition of ventilation is constant, and the constant then aeration status of same troubled water is also inevitable constant.Therefore, can't in a covering device, realize reinforcement to each stage of reaction process.
Simultaneously, continuously ferment and successive reaction will greatly reduce facility investment expense and running cost, but to relating to the reaction of liquid-solid two-phase, existing airlift reactor can't be realized liquid-solid separation, therefore also can't implementation procedure carry out continuously.Existing membrane bioreactor mostly is is with the slurry reactor and the film separating system that stir integrated, can realize successive reaction.Proposed a kind of ceramic membrane Reaction Separation system among the ZL 01 1 08189.9, this system contains biochemical reactor and the film pipe separator that is linked to be the recycle system, and system operates under negative pressure, can solve membrane pollution problem effectively by recoil aeration and gas lift aeration.Yet this system only is a kind of gas lift aerating system, the structure of its reactor is not an airlift reactor, its gas lift circulation is only at pipeline, and mixing efficiency in reactor body and mass-transfer efficiency are all lower, and can't satisfy the continuous film aeration and separate continuously and to the requirement of controlling respectively of mixing efficiency and mass-transfer efficiency.
In sum, develop a kind of novel gas lift type membrane reactor chemical industry and fermentation industry are all had major and immediate significance.
