Description

Rotary tangential flow tubular membrane filter

The utility model relates to a kind of membrane filtration machine, particularly be a kind of rotary tangential flow tubular membrane filter.

Membrane separation technique because efficient, energy-conservation, simple, cost is low, easy operating, has caused people's common concern.In chemical industry, light industry, medicine, food and environmental project, there are a large amount of highly difficult, high accuracy and the problem of efficiently separating, the membrane microfiltration in the membrane separation technique, film ultrafiltration are to solve one of effective ways of these difficult problems.But the extensive application of membrane separation technique in industrial production is subjected to the pollution effect of film.The pollution of film not only makes the permeation flux of film descend, and makes the film quality deterioration, causes shorten the service life of film.

The membrane filtration enhancements of taking so far has: the unstability that increase to flow (1), as make charging be dither, utilize channel cross-section clocklike to change, coiling curved channel on the face, outside the film pipe, adding spiral component etc.; (2) film or film structural component are rotatablely moved; (3) extra electric field power or ultrasonic field make particle away from face; (4) improve backwashing technology and recover membrane filtration flux etc.Though these enhancements have obvious effects, often complex structure, flow resistance are bigger, and the pressure loss is many, and energy consumption is higher.

In view of above reason, the purpose of this utility model is in order to provide a kind of cost low, handling ease, and the high rotary tangential flow of membrane flux is to the tubular membrane filter.

The utility model is achieved like this:

The utility model rotary tangential flow tubular membrane filter, comprise frame, be loaded on the body on the frame, be arranged at least one film pipe that is contained in vertically on the body of body, organism bottom has the bottom that contains the filtrate (liquid that communicates with the film pipe that is connected with body, the rotary tangential flow inlet duct that body upper has at least one side pipe wall and body wall tangentially to be connected, underpart has at least one rotary tangential flow outlet conduit, how much the depending on the needs of film pipe quantity.

Above-mentioned rotary tangential flow inlet duct is two, and symmetry is connected in outside the body.

Above-mentioned rotary tangential flow outlet conduit is two, and symmetry is connected in outside the body.

Above-mentioned rotary tangential flow outlet conduit one side pipe wall tangentially is connected with body wall.

Above-mentioned film Guan Weiyi root.

Above-mentioned film pipe is two.

Above-mentioned film Guan Weisan root.

Above-mentioned film Guan Weisi root, as required, the film pipe also can adopt more than five or five.

Above-mentioned body places film pipe connection loam cake, the film pipe connection lower cover composition that connector is connected with housing that pass through of housing upper and lower part by housing, and installation, dismounting, cleaning are conveniently.

The annular row air valve that is communicated with the body inner chamber is arranged at above-mentioned body top.

Referring to Fig. 1, in the utility model when work,, the suspension (liquid to be filtered) with certain pressure forms rotational shear and flows in the rotary tangential flow inlet duct is tangentially sent into the annular space of film pipe and body.The centrifugal intertia force that this moment rotation produces can overcome the drag force that sees through stream, makes it radially outward to move and away from face.The intensity of main flow rotation can make particle overcome the drag force of stream and go out pipeline from the rotary tangential flow of underpart and flow out outside the body, guarantees to see through stream again and passes film periosteum face smoothly and enter in the film pipe and flow out from organism bottom bottom filtrate (liquid.

Compare with existing membrane separation technique, the utlity model has following advantage:

1., simple in structure, handling ease, cost is low;

2., unit filtrate energy consumption is low, membrane flux Gao Jing.Sichuan Province university high speed hydraulics state key experiment test shows, in rotary tangential flow pressure is 0.01MPa～0.03MPa scope, the initial flux of rotary tangential flow single tube polypropylene PA film is 1.43～1.89 times of the initial flux of axial flow single tube polypropylene PA film, and rotary tangential flow single tube polypropylene PA film steady state flux is 1.58～2.51 times of axial flow single tube polypropylene PA film steady state flux;

3., applied widely, the film pipe of the utility model membrane filtration machine can select for use organic film pipe also can select inorganic film tube for use.According to the difference of selecting the film pipe for use, rotary tangential flow tubular membrane filter can be used in ultrafiltration such as sewage disposal and recovery, chemical industry, metallurgy, medicine, biotechnology, food and the micro-filtration.The application of micro-filtration in water treatment mainly is that degerming reaches the bulky grain that removes in anhydrating, as the reservoir water of muddiness being filtered the drinking water that can obtain clarifying.Microfiltration applications is in sterilised filtrations such as beverage and wine, vinegar, the end-filtration of ultra-pure water, air sterilization and filtering, pharmacy liquid particle-removing, virus and bacterium, the sterilised filtration of vein liquid etc.The utility model membrane filtration machine also can be used for the processing of metallurgical waste water and the recovery of rare metal and precious metal etc.; To single hose membrane filtration machine, for forming rotating flow, the flow velocity of main fluid is higher, and the flow of unit volume is bigger, can be directly used in the not very big scopes of capacity such as bioengineering and fine chemistry industry.To big range of capacity, can adopt multitube combination membrane filter.
