Description
Technical field
The present invention relates to a kind of external pressure hollow fiber membrane component.
Technical background
The features such as hollow fiber film assembly is large with its loading density, self-supporting, operating pressure is low, energy consumption is little obtain extensive use in fields such as water treatment, feed separation.Conventionally hollow fiber film assembly is that film silk is assembled to bunchy, is placed in tubular shell, and two ends are bonded in inner walls by resin cast, becomes one.
Hollow-fibre membrane in use, can form on surface dirty blocking up, and flux declines, and film silk is aging, and film properties declines, and needs to carry out membrane module replacing after a period of time.At present, hollow fiber film assembly mostly is the assembly of film silk and putamina one, during replacing, needs putamina to change together with film silk, and putamina can not re-use, and replacement cost is high, causes larger waste.Sometimes, due to the difference of membrane module size, the connecting line of membrane module also needs together to change, and causes larger waste.And film cortina shell integral component, is in use subject to the restriction of kit form, can only in parallelly use, the use of can not connecting, increases energy consumption in some occasion, is unfavorable for practical application.
Therefore need a kind of hollow fiber film assembly of exploitation badly, can change film core, the use of can connecting, saves replacement cost, in use can save energy, and reduces operating cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of external pressure hollow fiber membrane component of replaceable film core, in a putamina, can a plurality of film core series connection use, make more easy of integrationization of film device, and improve the filter efficiency of film, reduce membrane module replacement cost.
For addressing the above problem, technical scheme of the present invention is: the replaceable type hollow fiber film assembly of a kind of external pressure, comprise shell, film silk, see through liquid pipe, assembly end-blocking, it is characterized in that shell and film silk are bonding by epoxy resin or polyurethane casting, be respectively water inlet end and water side; Water inlet end place film silk is closed pore, is distributed with inlet opening on it, for stoste, enters; Place, water side film silk is perforate, is distributed with dense water out on it, for concentrate, discharges; Permeate comes together in the cavity between water side and assembly end-blocking by the perforate of water outlet terminal membrane silk, then discharges by connecting the liquid pipe that sees through seeing through on liquid pipe and assembly end-blocking of membrane module central authorities, forms filtered solution.
Described membrane module is characterised in that seeing through liquid pipe is positioned at membrane module center, from water inlet end to water side, runs through assembly, communicates, and from water inlet end, lean out certain length through liquid pipe with seeing through liquid air chamber.
Described membrane module is characterised in that water outlet is distolateral an assembly end-blocking, on assembly end-blocking, there is concentrated solution outlet and see through liquid pipe, concentrated solution outlet is connected with dense water out on water side, see through liquid pipe range and go out end-blocking, communicate with cavity between assembly end-blocking and assembly water side casting resin, water side hollow-fibre membrane perforate communicates with cavity.
Described membrane module is characterised in that there is O-ring seal in assembly water inlet end outside, plays the sealing function between assembly and putamina, prevents that stoste from directly not discharging by membrane module.
Below in conjunction with embodiment and accompanying drawing thereof, be described in further detail the present invention.

Specific embodiment
Technical scheme of the present invention is: the replaceable type hollow fiber film assembly of a kind of external pressure, comprise shell and film silk, and it is characterized in that shell 4 and film silk 5 are bonding by epoxy resin or polyurethane casting, be respectively water inlet end 2 and water side 6; Water inlet end 2 place's film silks are closed pore, are distributed with inlet opening 10 on it, for stoste, enter; Water side 6 place's film silks are perforate, are distributed with dense water out on it, for concentrate, discharge; Permeate comes together in the cavity 8 between water side 6 and assembly end-blocking 9 by water side 6 film silk perforates, then discharges by connecting the liquid pipe 1 ' that sees through seeing through on liquid pipe 1 and assembly end-blocking 9 of membrane module central authorities, forms filtered solution.
In order to make feed liquid enter membrane module distributed uniform, on water inlet end 2, leave water inlet 10, water inlet 10 diameters are 5-20mm, in water inlet end regular distribution, as shown in Figure 2, water inlet number, at 4-100, is determined according to membrane module diameter dimension.In membrane module water side 6, leave discharge outlet 7, discharge outlet 7 diameters are 8-25mm, regularly arranged, and staggered with water inlet, and number is few compared with water inlet, 2-50.
In order to collect and to discharge through liquid, at membrane module, be provided with through liquid pipe 1, see through liquid pipe 1 and be positioned at membrane module central authorities, connect water inlet end 2 and water side 6, concordant with water side, grow water inlet end 3-6cm, see through liquid pipe 1 diameter 10-40mm.
In order to make to separate through liquid and concentrate, in water side, 6 places are bonded with assembly end-blocking 9, between water side 6 and end-blocking 9, have cavity 8, and on water side 6, hollow-fibre membrane perforate communicates with cavity 8, and the liquid pipe 1 ' that sees through seeing through on liquid pipe 1 and end-blocking 9 also communicating with cavity 8.On end-blocking, also have in addition concentrate pipe 7 to be connected with the delivery port 7 on water side 6, by concentrate with through liquid, separate.Cavity 8 is of a size of 1-3cm.
In order not make the stoste membrane module of all flowing through, in membrane module water inlet end outside, sealing ring 3 is housed, sealing ring 3 is combined closely with putamina 12, prevents that stoste is by the gap leakage of membrane module and putamina.
The operation principle of membrane module of the present invention is that, when film mask work, feed liquid enters from the inlet 13 of putamina 12, water inlet 10 on assembly water inlet end 2 enters membrane module, by the delivery port 7 on membrane module water side 6, flow out, then enter next membrane module, finally from the liquid outlet 14 of putamina, flow out; Seeing through the hollow-fibre membrane perforate of liquid on membrane module water side 6 comes together in cavity 8, through seeing through liquid pipe 1,1 ', flow out again, between assembly and assembly, by connector 11, be connected, and then discharge by the liquid collecting pipe 15,15 ' that sees through of putamina termination, obtain filtered solution.
Membrane module structure of the present invention is applicable to 2 inches of above external pressure hollow fiber membrane components, is specially adapted to heavy caliber membrane module, as 4 inches, 8 inches membrane modules, can be used for the film device of scale, serialization production.In addition, the present invention is applicable to microfiltration membranes, milipore filter, NF membrane, reverse osmosis membrane.The 4 inches of membrane modules of take are example, and experiment shows, membrane module of the present invention can be realized nanofiltration process, has improved filter efficiency, guarantee membrane filtration characteristic.
