An indispensable link in treatment process.
Hollow fiber ultrafiltration membrane is one kind of ultrafiltration membrane.It is the most mature and advanced a kind of technology in hyperfiltration technique.
It is covered with micropore on doughnut tube wall, the molecular weight that aperture can retain substance is bigger, and molecular cut off is up to thousands of to tens
Ten thousand.Raw water respectively constitutes external-compression type and inner pressed on the outside of doughnut or the pressurized flow of inner cavity.Hollow fiber ultrafiltration membrane is even
In continuous normal course of operation, it is necessary to which timing, the cleaning for periodically carrying out various methods, common cleaning method have back pressure backwash
Method, isobaric hydrodynamic cleaning method and chemical cleaning method, back pressure backwash method be with clean water, from ultrafiltrate side enter to front into
Row rinses.Power of the ultra-filtration process only with pressure as UF membrane, therefore separator is simple, process is short, easy to operate, easy
In control and maintenance.
Traditional hyperfiltration membrane assembly be easy to cause film wire dirt stifled when treating wastewater, and film wire dirt is stifled, and to will result in water yield fast
Speed decline, and because of its reasons in structure, backwash effect is bad, and permeant flux cannot restore very well, often will affect production and causes
Shortened equipment life.
Utility model content
Purpose of the utility model is to solve the above problems, provide a kind of polysulfone hollow fiber ultrafiltration membrane system.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of polysulfone hollow fiber ultrafiltration membrane system, including
Filter cylinder, filter cylinder top are fixedly installed upper end cover, and filter cylinder lower part is fixedly installed lower cover, is provided with ultrafiltration membrane filaments in filter cylinder,
Lower cover bottom center is provided with air inlet, and lower cover lower side is provided with inlet, is arranged at upper end cover top center
There is liquid outlet, the ultrafiltration membrane filaments use hollow fiber film yarn, and the hollow fiber film yarn is close to upper end cover
One end is fixed, and the other end freely swings in filter cylinder.
The hollow fiber film yarn is fixed in the bearing of upper end cover using gel.
The hollow fiber film yarn is using wedge structure, the length of wedge structure section film wire on the inside of bearing
For 20-40mm.
The length of the wedge structure section film wire is 30mm.
The film wire of the wedge structure section is made of PE and PVDF composite material, remaining hollow fiber film yarn uses
PVDF material is made.
The film wire thickness of wedge structure section is 1.2 times of remaining hollow fiber film yarn thickness.
The junction of upper end cover and lower cover and filter cylinder is provided with gasket, between upper end cover and lower cover and filter cylinder
It is fixed using clip.
The utility model has the beneficial effects that: the utility model needle water process, Sewage advanced treatment provide a kind of gradual change
Formula hollow fiber ultrafiltration membrane element can preferably improve water process, surpass in the system of Sewage advanced treatment using the membrane component
The operation for filtering device makes the safer and more effective stable operation of system, improves equipment service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of hollow fiber film yarn.
Fig. 3 is the structural schematic diagram of wedge structure section film wire.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model provides a kind of polysulfone hollow fiber ultrafiltration membrane system, including filter cylinder 1,1 top of filter cylinder is solid
Surely it is provided with upper end cover 2,1 lower part of filter cylinder is fixedly installed lower cover 3, and ultrafiltration membrane filaments 4,3 bottom of lower cover are provided in filter cylinder 1
Air inlet 5 is provided at center, 3 lower side of lower cover is provided with inlet 6, is provided with out liquid at 2 top center of upper end cover
Mouth 7, ultrafiltration membrane filaments 4 use hollow fiber film yarn, and hollow fiber film yarn is fixed in one end close to upper end cover 2, separately
One end can freely swing in membrane module filter cylinder 1.The swingable structure in the film wire one end can in backwash effective anti-pollution
Stifled, backwash intensity is big, can adapt to the biggish waste water of viscosity, in addition can be passed through air from air inlet in backwash, freely put
Dynamic structure makes air bump rinse operation pass through film wire beam, aggravates the disturbance and rubs mutually of film wire, can preferably remove pollutant.
Hollow fiber film yarn 4 is fixed using gel 8 in the bearing of upper end cover 2.Upper end cover 2 and lower cover 3 and filter
The junction of cylinder 1 is provided with gasket 9, and it is fixed that clip 10 is all made of between upper end cover 2 and lower cover 3 and filter cylinder 1.
As shown in Figures 2 and 3, hollow fiber film yarn 4 is using wedge structure 11, wedge shape knot on the inside of bearing
The length of structure section film wire is 30mm.In this section of wedge structure, water flow can only flow from inside to outside from film wire, and cannot be outside film wire
Inwardly flowing, therefore this section of film wire does not produce water.At runtime, pollutant is easiest to assemble in film wire bearing membrane module, in film
Use inside for the film wire of taper structure in the 30mm length of silk bearing, coarse inside outer smooth, water flow cannot be from film wire
Outside enters inside film wire, can reduce natural adhesive force and water flow adhesive force of the pollutant in this length section to film wire in this way,
It is not easy to pollute the removing that object is immobilising " dead zone ", when facilitating backwash to pollutant.
The film wire of wedge structure section is made of PE and PVDF composite material, remaining hollow fiber film yarn uses PVDF
Material is made.The film wire thickness of wedge structure section is 1.2 times of remaining hollow fiber film yarn thickness.Wherein PE material can
Increase the flexibility of film wire, it is herein the position for being easiest to fracture of wire that PVDF material, which guarantees that film wire keeps certain rigidity, therefore is increased
Wire broken rate can be reduced by adding thickness, and extend the film wire service life.
When operating normally, waste water enters in filter cylinder polysulfone hollow fiber ultrafiltration membrane system from the inlet on lower cover, in
The filtering of fibre ultrafiltration film wire produces water and is pooled in upper end cover and flowed out by liquid outlet.With the extension of runing time, outside film wire
Assemble more and more pollutants and need to carry out backwash when film wire inside and outside differential pressure is reached to a certain degree in portion.When backwash, backwash water
Enter from liquid outlet, to rinsing outside film wire inside hollow fiber film yarn, the pollutant of film wire external aggregation removed,
It is discharged with water flow from water inlet.It can also be passed through compressed air from air inlet when backwash, aggravate the disturbance and phase mutual friction of film wire,
Pollutant can preferably be removed.
The above is preferred embodiments of the present invention, it is noted that for those skilled in the art,
The present utility model is not limited to the above embodiments, under the premise of not departing from the utility model general idea, can also make
Several changes and improvements, these also should be considered as the protection scope of the utility model.
