Property, it is national mainly to originate from Germany, the U.S. and Israel etc. for existing high-precision filter filter core in the world, these filter cores mainly with
The metal wire knitted strainer such as S2507,904L stainless steel or Monel M400 alloys or multilayer metal sintering composite web, stainless steel
Based on welding wedge shape net.But among actual use process, ballast water treatment plant filter is in serious pollution waters at present
During operation, still regular generation frequently backwashes, and even generation filter is completely plugged sometimes, the situation for shutdown of alarming,
The cost of business operation of ship is added, reduces efficiency of navigation.
The content of the invention
Its purpose of the invention, which is that, provides a kind of nanoscale TiO for full-automatic back washing filter2Automatically cleaning is filtered
Core, solves frequent backwash and filtering that current ballast water treatment plant filter occurs when serious pollution waters is run
Device clogging.
Adopt the technical scheme that to achieve the above object, a kind of nanoscale for full-automatic back washing filter
TiO2Automatically cleaning filter core, including multiple filter cores are circumferentially distributed the filter core layer being fixed in filter, it is characterised in that the filter
Core includes inner protective layer, filter layer, enhancement layer, external protection, and the filter layer and reinforcement are placed on inner protective layer and outer protection
Between layer；The establishment filter structure that the filter layer forms for super duplex steel 2507 (UNS S32750,1.4410) sintering；
The inner protective layer, external protection are super duplex steel 2507 (UNS S32750,1.4410) load nanoscale TiO2Material
Sinter the establishment filter structure formed；The enhancement layer is TiO2The netted plank frame that material is made.
Beneficial effect
The present invention has the following advantages compared with prior art.
The present invention utilizes nano-TiO2Photocatalytic and Superhydrophilic, by nano-TiO2It is supported on filter element,
The microorganism in ballast water and organic pollution can be removed, reduces and carries water treatment facilities filter in serious pollution waters fortune
Row dismounting, cleans the frequency of filter core, increases the service life of filter core, can be widely used for full-automatic back washing filter.

Embodiment
Below in conjunction with the accompanying drawings, the present invention is further illustrated.
The present apparatus is circumferentially distributed the filter core layer 2 being fixed in filter 1 including multiple filter cores 3, as Figure 1-Figure 8,
The filter core 3 includes inner protective layer 4, filter layer 6, enhancement layer 5, external protection 7, and the filter layer 6 and enhancement layer 5 are placed in interior guarantor
Between sheath 4 and external protection 7；The filter layer 6 forms for super duplex steel 2507 (UNS S32750,1.4410) sintering
Establishment filter structure；The inner protective layer 4, external protection 7 are that super duplex steel 2507 (UNS S32750,1.4410) is negative
Carry nanoscale TiO2The establishment filter structure that material sintering forms；The enhancement layer 5 is TiO2Material is made netted board-like
Structure.
The filter core layer 2 is individual layer or Multi-layers distributing.
The filter core is cylinder integral filtering element, is process by different structure form strainer, as shown in Figure 1, the filter core by
Four layers of sintering strainer composition, are respectively from inside to outside：Inner protective layer 4, filter layer 6, enhancement layer 5, external protection 7.Wherein, filter
The establishment strainer that layer 6 forms for super duplex steel 2507 (UNS S32750,1.4410) material sintering, inside and outside two layers of protective layer material
Matter is all super duplex steel 2507 (UNS S32750,1.4410) load nanoscale TiO2The establishment strainer that material sintering forms,
Enhancement layer is TiO2The netted plank frame being made.Whole filter core is worked as with the formal distribution of cylinder monoblock type in filter
In.Intermediate filter layer shown in Fig. 3 is coated on filter core enhancement layer shown in Fig. 4, and the filtering accuracy of whole filter core is ensured by it.
Coarse filtration is also acted as while skeletal support is played the role of for filter core enhancement layer shown in Fig. 4 and photocatalytic oxidation degradation is organic
The self-cleaning effect of thing, the filter core protective layer shown in Fig. 5, which divides inside and outside two layers, to be coated on outside filter layer and enhancement layer, is risen and is improved entirely
Coarse filtration is also acted as while the effect of filer element strength and protection filter layer and photocatalytic oxidation degradation organic matter is self-cleaning
Effect.
As shown in figure 8, the full-automatic back washing filter, cylinder integral filtering element as shown in Figure 2 is provided with shell,
The arrangement of its filter element can be designed as the laminates shown in individual layer arrangement or Fig. 7 shown in Fig. 6 as needed
Put.
The filter element of the present invention is cylinder integral filtering element, is process by different structure form strainer, the filter core
It is made of four layers of sintering strainer, is respectively from inside to outside：Protective layer, filter layer（Molecular size key-course）, enhancement layer, protection

The establishment strainer formed, inside and outside two layers of protective layer material are all that super duplex steel 2507 (UNS S32750,1.4410) load is received
Meter level TiO2The establishment strainer that material sintering forms, enhancement layer TiO2The netted plank frame being made.The filter core applies
The mechanism of titanium dioxide material light-catalyzed reaction:
TiO2 + hγ → e- + h+
h+ + H2O →·OH+ H+
e- + O2 →·O2 -
·O2 - + H+ →HO2·
2HO2·→O2+H2O2
H2O2+·O2 -→·OH +OH-
In filter process, the TiO in filter core material2Constantly carry out photocatalytic degradation and remove the organic matter of cartridge surface, reach
To self-cleaning effect, filter core is also played one's part to the full in serious pollution waters, be optimal the performance of filter
Change.
