Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of improved Unitary suspend bed inorganic membrane reactor in order to solve existing the problems referred to above that exist, to simplify the making of membrane module, thereby make full use of the useful space of reactor, reduce equipment investment and operating cost.
The technical solution of the utility model is: Unitary suspend bed inorganic membrane reactor, form by reactor 6, seal cover 2, agitating device 1 and filtrate output tube 10, be provided with the membrane separation assemblies of forming by inorganic film tube 7 in the reactor 6, it is characterized in that the end sealing of inorganic film tube, the other end links to each other with agitating device 1, communicates and can rotate with agitating device, agitating device 1 is the hollow tube of lower ending opening, outside the logical still in agitating device 1 lower end, and double as filtrate output tube 10.
Preferred still contains 1～10 group membrane separation assemblies.The preferred film separation assembly is made up of 1～10 inorganic film tube.The hollow tube of preferred described shaft lower ending opening is an inorganic film tube.
Preferred TiAl alloy of above-mentioned inorganic film tube or stainless steel metal material membrane.
In sum, the utility model is arranged at the inoranic membrane separation assembly in the still of suspended-bed reactor, the reaction of suspended state material and the solid-liquid separating equipment of suspended material are integrated, can carry out material reaction and Separation of Solid and Liquid simultaneously in the reactor, i.e. one side continuous feed in reactor is reacted, by the sieving actoion of inoranic membrane, liquid phase material is separated discharge on one side.Wherein, the solid catalyst tunicle of suspension is trapped in the reactor and continuation participates in reaction, and liquid phase material then sees through inoranic membrane and enters in the film pipe also by high pressure or negative pressure outflow reactor.In the utility model, inorganic film tube is also used as paddle both as filter medium usefulness simultaneously.The film pipe does not stop to rotate in fluid as paddle makes the film tube-surface constantly be subjected to washing away of fluid, reduced the deposition of solid catalyst effectively on the film surface, make inoranic membrane can keep higher permeation flux, thereby make required membrane area reduce, increase the useful space of reactor, the feasibility of increase system.
Beneficial effect:
Owing to do not use bolt, gasket seal, nut etc. to fix the film pipe,, the problems such as maintenance, solid particle loss of membrane module have been reduced so there is not film seal of tube problem in the utility model; Security, the continuity of operation have been improved; Improved the useful space of reactor; Simplify the making of membrane module greatly, reduced equipment investment.In addition, high temperature resistant, the corrosion-resistant and plasticity of TiAl alloy or stainless steel and other metal materials film is strong etc., and advantage makes the utility model implement easily.As seen the utlity model has the saving equipment investment, can simplify technology, improve the membrane separating property plurality of advantages.
