Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The synoptic diagram of immersion hollow fiber film assembly of the present utility model as shown in Figure 1, many hollow-fibre membrane silks 5 are fixed by two sealing plys that are cast in barrel 3-1, the 3-2, in order to improve the work-ing life of film silk, sealing ply is made up of epoxy sealing layer 1-1,1-2 and urethane sealant layer 2-1,2-2.Because urethane sealant layer is softer, helps the protective membrane silk.Barrel 3-1 is connected with blind nut 4-1, and barrel 3-2 is connected with blind nut 4-2, and the hollow space of every hollow-fibre membrane silk is opened on the sealing ply both ends of the surface.Blind nut 4-2 is provided with inlet mouth 10, and blind nut 4-1 is provided with water outlet 11.Aeration air inlet post 7 is installed at the inlet mouth place, and described aeration air inlet post 7 one ends are communicated with aerating apparatus 6, and the other end and inlet pipe 8 are pegged graft.Many hollow-fibre membrane silks are divided at least two film tow, can parallel or intersection between each film tow.Form the aeration passage between each film tow, like this, bubble rises along the aeration passage during aeration, and stepless action is in black box film silk, and aeration more evenly, rationally.
Gas is evenly distributed up and down when making aeration, and realize that both-end produces water, improve water production rate, the synoptic diagram of the aerating apparatus in the utility model such as Fig. 2, shown in Figure 3, described aerating apparatus comprises the aeration body 15 of open column shape body structure, be provided with mutual disconnected collection chamber 13 and collecting chamber 16 in the described aeration body, the aeration body outside is connected with a plurality of closed air chambers that are communicated with collection chamber 14, and each closed air chamber is provided with a plurality of solarization air caps.Closed air chamber is evenly distributed between a plurality of film tow.Be provided with a plurality of posticums in the collecting chamber 16, be provided with a plurality of prosopyles 19 in aeration body lower end, the end face of prosopyle and membrane module cast sealing ply forms same plane.The aeration body is provided with the water channel 17 that is communicated with prosopyle and posticum.The bottom of collection chamber 13 is tightly connected by sealing-ring with the aeration air inlet post 7 that has gas passage 18.For transport, installation and easy to maintenance, and realize that both-end produces water, is provided with supporting tube 9 between two sealing plys.Supporting tube one end opening is on the end face of water outlet end sealing ply 1-1, and the other end is communicated with the collecting chamber 16 of aerating apparatus.Aeration air inlet post 7 is one to extend out the formula structure, innerly adopts sealing-ring and the 8 sealing grafting of outside tracheae.
Gas enters collection chamber 13 by the gas passage 18 in outside tracheae 8, the aeration air inlet post 7, thereby enters closed air chamber 14 by pore 12, enters between the film tow by solarization air cap and forms aeration.Because solarization air cap quantity is many, be evenly distributed, thereby the gas that enters in the membrane module is evenly distributed up and down, form the air-flow of continous-stable, aeration is even up and down to make the film silk, and it is good to remove pollution effects, guarantees that the assembly continous-stable uses.And lower stress unanimity on the film silk has prolonged film silk work-ing life.
When producing water, filtered water sees through the film tow, enters between sealing ply 1-1 and the blind nut 4-1 from film silk one end, and flows out from producing the mouth of a river.Simultaneously, the filtered water of the film silk the other end enters between sealing ply 1-2 and the blind nut 4-2, enter the prosopyle 19 of aeration body bottom under pressure, enter collecting chamber 16 by the water channel on the aeration body 17, posticum, flow out from the membrane module the other end by supporting tube 9 then, realize that both-end produces the single-ended water outlet of water.Supporting tube had both played the effect of support, had again to collect the effect of producing water, and the film core volume is dwindled, and increased the arranging density of assembly unit surface, reduced the membrane cisterna floor space, reduced construction costs.
The utility model is by the improvement to membrane module structure and aeration mode, can increase water production rate, and effectively increasing working time of system, mitigation system is safeguarded the work-ing life that the pressure that brings improves membrane module, finally reaches the effect that obtains bigger income with lower running cost.
Although relate to a kind of immersion hollow fiber film assembly and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
