Description
Technical field
The present invention relates to field of water treatment equipment, specifically, it is related to a kind of modularization external pressure type hollow fiber membrane component
And preparation method thereof.
Background technology
Membrane separation technique is the new technology interdisciplinary for flourishing in the world in the sixties in last century, with
Extensive use of the membrane separation technique in fields such as chemical industry, environmental protection, pharmacy, market for all kinds membrane module demand increasingly
It is vigorous.
Hollow-fibre membrane with its compared with specific surface area high, treating capacity is big, intensity is high the advantages of be widely used in water
The liquid separation fields such as treatment.Hollow fiber film assembly principal mode has：Curtain hollow fiber film assembly, pillar hollow-fibre membrane
Component.Column type hollow fiber membrane modular with its loading density it is big, operating pressure is low, aquifer yield is high the features such as in water process, material
It is used widely in the fields such as separation.Column type hollow fiber membrane modular is divided into inner pressed hollow fiber film assembly and external-compression type again
Two kinds of hollow fiber membrane module, because external pressure column type hollow fiber membrane modular runner is wider, resistance to water-flow is smaller, while can use
Aeration means, slow down film silk pollution process and reinforcing face mass transfer, have obtained wider application.
In the actual mechanical process of the reinforcing gentle scouring of face mass transfer, component internal even fluid distribution is directly affected
The formation of face cake layer and concentration polarization phenomenon, is the key index of assembly property so as to have influence on the performance of whole branch component
One of.In actual use, to film silk, either gas is cleaned or backwashed in putamina, is inevitably difficult to cleaning and is close to
The film silk at component two ends, so as to produce cleaning " dead band ".
At present, run by the way of " dead end " filtering more than the operator scheme of external pressure column type hollow fiber membrane modular, i.e., it is outer
Fed using bottom more than pressure column type hollow fiber membrane modular, charging is guided to by Mo Si areas by the solarization air cap of gas-liquid distributor
Domain.
In recent years, Chinese patent " A of CN 104815558 " discloses a kind of hollow fiber film assembly, it is characterised in that in
Hollow fiber film silk lower end is encapsulated in head cluster, and head cluster together vertically may be used with many hollow fiber film thread lower ends in component internal
Move freely, during aeration, gas is entered by gap between head cluster, the gap between head cluster and package shell, and head cluster exists
It is axially moved along component internal under the buoyancy of air water, increase film silk jitter amplitude, but deficiency is movable boundling
Head increases technology difficulty in the production installation process of component, and it is right that head cluster and head cluster and the gap between putamina are difficult to
Gas-liquid plays equally distributed effect；Chinese patent " CN202199270U " discloses a kind of outer with turbulence promoter structure
Pressure type hollow fiber membrane module, it is characterised in that at least one turbulence promoter of putamina inside, and turbulence promoter is interspersed sets
Put between many hollow fiber film threads, reduce concentration polarization phenomenon in filter process, effectively control fouling membrane, but deficiency
Place is that the addition of multiple turbulence promoters reduces the packed density of film silk；Chinese patent " CN102658032A " is disclosed
A kind of external pressure type hollow fiber membrane component, it is characterised in that the center collector pipe outside in film silk region is evenly distributed with and a plurality of is in
Radial rectangle effluent trough, every rectangle exhalant canal by being opened in center collector pipe inner space, annular collecting vat with
Radially cut each rectangle exhalant canal to be connected, the contact and pollution that are designed with beneficial to fluid with film silk of a plurality of runner
The timely exclusion of thing, but the addition of a plurality of tank greatly reduces the membrane area of single branch component.
Therefore, exploitation one kind is conducive to producing equally distributed wall shear stress in film silk wall, be easy to adjusting film silk with
Solarization air cap arrangement makes even fluid distribution, and quick release changes clothes the modularization external-compression type membrane module of assembling, for having widened
The industrial applicability of machine hollow fiber film assembly is significant.
