Description
Technical field
The utility model relates to water treatment field, in particular, relates to a kind of termination parts, hollow fiber film assembly and membrane filter unit.
Background technology
Membrane separation technique has been widely used in the fields such as the isolated by filtration of water purification process or liquid, different according to the version of membrane filtration system, can be divided into housing adding pressure type membranous system and submerged membrane system.
Wherein submerged membrane system can process containing the liquid to be filtered compared with the pollutant such as high suspended matter, mud.Membrane module in submerged membrane system is general also with the liquid collecting cavity collected for filtered fluid and the aeration structure removing film silk surface contaminant for disturbance film silk.In existing immersion membrane filtration system, in the middle part of membrane module, normally discharged the pollutant on film silk surface to surrounding by side surface direction.But the liquid collecting end of water produced for membrane module or is with the end of liquid collecting end and aeration structure simultaneously, lacking effective blowdown means.
Membrane module in submerged membrane system often adopts liquid collecting end and aeration structure to be placed on the mode at membrane module two ends respectively, lower end built-in aeration structure or the reserved hole that aeration bubbles can be made to pass, upper end arranges the chamber structure that filtered fluid is collected, the aeration bubbles that utilizes lower end to overflow during work drives hollow-fibre membrane disturbance, amasss attachedly be deposited to the object that hollow-fibre membrane surface reaches cleaning and filtering membrane module with decreasing pollution thing.Part pollutant in aeration process in liquid to be filtered is hampered after rising to membrane module upper end root and discharges towards periphery, period there will be pollutant in membrane module upper end root alluvial problem, cause secondary pollution, and extend with submerged membrane System production time and pollute aggravation.
Although the membrane module structure that Chinese Patent Application No. CN200810052589.4 discloses alleviates above-mentioned membrane module upper end root alluvial pollution problem, specially drain outlet, end is set with upper end, and liquid collecting end and aeration structure are placed on membrane module lower end simultaneously.But membrane module lower end built-in aeration structure, again there is product water chamber, bottom is made to be overall cecum form design, when aeration stops, again depositing during pollutant natural subsidence in liquid to be filtered to membrane module lower end root and cause dirt, and aeration structure may be caused to block.
No matter take which kind of frame mode, the end of membrane module has at least one end to be overall cecum form design, described overall cecum form design refers to the passage (drain outlet) that membrane module end does not make pollutant and discharges, in overall that end of cecum form design normally liquid collecting end, or be with the end of liquid collecting end and aeration structure simultaneously.The always design in overall cecum of liquid collecting end end, causes liquid collecting end end film silk root easily to deposit pollution.If design is end simultaneously with liquid collecting end and aeration structure in overall cecum, not only this cecum side form silk root easily deposits pollutions, and aeration structure also may cause aeration to lose efficacy because blocking.So the structure of current membrane module becomes the alluvial of membrane module cecum side form silk root to pollute, and aeration structure also may be made to block and lost efficacy.
As occurred, hollow-fibre membrane is damaged in use procedure for hollow fiber film assembly, can cause and filter cutoff performance decline, therefore repair maintenance is needed, and the repairing of hollow-fibre membrane is divided into two kinds of modes by membrane module structure form difference, the first is when membrane module filtered fluid collection chamber is the removable assembly structure adopting bolt or screw, this chamber can be opened repair from hole end surface in hollow-fibre membrane, but this kind of design can cause membrane module end profiles size to increase, thus make membrane module that the increase of occupation of land demand is installed, and increase cost of investment; The second is that this membrane module designs is compact when membrane module filtered fluid collection chamber is non-disconnectable monolithic construction, can improve membrane module appearance and size large, take up an area large problem; But membrane module is repaired and can only be carried out at doughnut film outer surface, be positioned at the hollow film fiber film contact difficulty of membrane module root center, when thus the hollow film fiber film of membrane module root center occurs damaged, can not Efficient software patching be carried out.
