(right end of Fig. 1 fiber film wire 3 and left end), and film wire produces water end (W.E.) and offers The film wire that connection produces water flow passage produces water opening, the closing of film wire free end.Film wire produces water end (W.E.) and passes through sealant 2, protrudes into and produces water chamber 12. The part of the surface that fiber film wire 3 is located at sealant 2 is enclosed with protective film, and is fixed in sealant 2 by sealant.Film wire is certainly It is swingable by holding.

Shell 1 includes that opposite shell raw water end 101 and shell produce the (right part and a left side of Fig. 1 shell 1 of water end (W.E.) portion 102 End), shell raw water end 101 offers the raw water inlet 13 of connection water purifying chamber 11, and shell produces water end (W.E.) portion 102 and offers connection Produce the production water out 14 of water chamber 12.

Referring to FIG. 3, being additionally provided with the first hollow tube 41 in water purifying chamber 11, the first hollow tube 41 includes that the first opposite pipe is close Sealing end and the first pipe open end (right end of the first hollow tube of Fig. 3 41 and left end).First seal of tube end is fixedly connected with shell raw water End 101, the inside of the first hollow tube 41 form the first raw water transverse flow channels 111, and it is lateral that raw water inlet 13 is connected to the first raw water Runner 111.It is spaced preset width value between first pipe open end and sealant 2, is formed between the first pipe open end and sealant 2 First raw water longitudinal direction runner 121.The second raw water transverse flow channels 112 are formed between the outer tube wall and shell 1 of first hollow tube 41.The Plurality of fibers film wire 3 is distributed in one raw water transverse flow channels 111 and the second raw water transverse flow channels 112.

Concentrated water outlet 15,15 connection water purifying chamber 11 of concentrated water outlet are also provided on shell 1.Specifically, concentrated water outlet 15 connects The logical one end of second raw water transverse flow channels 112 far from the first raw water longitudinal direction runner 121.

As shown in Fig. 3 filled arrows, raw water flows into the first raw water transverse flow channels 111 from raw water inlet 13, then flows into first Raw water longitudinal direction runner 121 flows into the second raw water transverse flow channels 112 again later, finally from 15 outflow of concentrated water outlet.As Fig. 3 is hollow Shown in arrow, a part of raw water penetrates the membranous wall of fiber film wire 3, into water flow passage is produced, produces water opening inflow by film wire and produces water Room 12 is flowed out finally by water out 14 is produced.

The cross-sectional area of first raw water transverse flow channels 111 is less than the cross-sectional area of water purifying chamber 11, then the first hollow tube 41 makes The flow channel cross-section product for obtaining raw water reduces, and one timing of pressure, water flow is accelerated, and film wire free end can freely be put under flow action It is dynamic, mutual collision friction, and then it is easy to fall off the pollutant for being attached to 3 surface of fiber film wire.Raw water is by the first raw water transverse direction Runner 111 changes direction and enters the first raw water longitudinal direction runner 121, can effectively to sealant 2 and be fixed on sealant 2 Fiber film wire 3 be rinsed.

The inner tubal wall of the first hollow tube 41 of several perforations and the first limbers of outer tube wall are offered on first hollow tube 41 410, then each first limbers 410 is connected to the first raw water transverse flow channels 111 and the second raw water transverse flow channels 112.Specifically, X First limbers 410 is distributed to form the first limbers group, X≤1 along the axis direction of the first hollow tube 41.On first hollow tube 41 Equipped with Y the first limbers groups, axis equidistantly distributed of Y the first limbers groups around the first hollow tube 41, Y≤1.It is any The distance between the film wire free end of fiber film wire 3 and sealant 2 are greater than between any first limbers 410 and sealant 2 Distance.

Water flow in first limbers 410 can destroy second laminar condition, increase turbulent water, be unfavorable for miscellaneous in water The deposition of matter prevents the pollution of hollow-fibre membrane.

Fig. 1 to Fig. 2 is please referred to, in the present embodiment, for ease of description, by being set in the first raw water transverse flow channels 111 Fiber film wire 3 is defined as central film wire 31, and the fiber film wire 3 not being set in the first raw water transverse flow channels 111 is defined as outer paraderm Silk 32.

All center film wires 31 are divided for several central film wire groups, and the film wire of the central film wire 31 in each center film wire group is free End forms several central membrane tow by sealant or beaming device boundling.

It is respectively corresponded in each central membrane tow equipped with an elastic supporting bar 5, one end fixed connection and sealing of elastic supporting bar 5 Layer 2, the other end and corresponding film wire free end boundling.

Raw water in the first raw water transverse flow channels 111 caused by turbulent flow it is larger, film wire phase may occur for central film wire 31 Phenomena such as mutually tangling, bending causes the reduction of hollow fiber film assembly separative efficiency.The film wire free end of central film wire 31 is carried out Simultaneously elastic supporting bar 5 is arranged in boundling, can effectively avoid the generation for phenomena such as central film wire 31 intertwine with each other and bends, and it is each in Relative displacement occurs between the film wire beam of centre, makes mutual collision friction between central film wire 31, and then make to be attached to central film wire 31 The pollutant on surface is easy to fall off.

It is understood that all periphery film wires 32 can also be similar with central film wire 31, after being divided into several peripheral film wire groups, The film wire free end of each periphery film wire group inner peripheral film wire 32 passes through sealant or beaming device boundling.Since peripheral film wire 32 is sent out The raw probability for intertwineing with each other or bending is lower, and peripheral film wire 32 can also be without boundling.

In the present embodiment, shell 1 includes hollow cylinder 103, and the inside of hollow cylinder 103 is water-purifying cavity.It is hollow The both ends of cylindrical body 103 are respectively fixedly connected with shell raw water end 101 and shell produces water end (W.E.) portion 102.101 He of shell raw water end Shell production water end (W.E.) portion 102 is symmetrical, is hemisphere.It is understood that shell raw water end 101 and shell produce water end (W.E.) portion 102 can also be vault construction.

To improve separative efficiency, raw water inlet 13 produces the axis of water out 14 and the first hollow tube 41 and hollow circuit cylinder The axis of body 103 is on same straight line.

The utility model embodiment passes through the setting of the first hollow tube 41, so that the flow channel cross-section product of raw water reduces, pressure One timing of power, the flow velocity of raw water are accelerated.Film wire free end can freely swing under flow action, mutual collision friction, raw water Enter the first raw water longitudinal direction runner 121 from the first raw water transverse flow channels 111, can effectively to sealant 2 and be fixed on close Fiber film wire 3 on sealing 2 is rinsed.Water flow in first limbers 410 can be destroyed in the second raw water transverse flow channels 112 The laminar condition of raw water increases turbulent water, is unfavorable for the deposition of impurities in water, therefore the utility model can effectively prevent The pollution of fiber film wire increases the service life of hollow fiber film assembly.
