Description
Technical field
The utility model is related to liquid filtration art, refer in particular to it is a kind of be used to eating, industrial liquid filtering, processing work
Taper filter core, cartridge structure and the liquid precise filter of caused waste water, sewage and waste liquid during industry is produced or lived.
Background technology
Contained harmful substance mainly includes particulate matter and organic matter in industry at present and sanitary sewage, wherein particulate matter except compared with
Outside big solid and bioflocculation particulate matter, sick bacterium, virus, microorganism etc. can also be classified as particle species, their diameter one
As in micron level or more.
Equally, the particulate separation of the edible drink such as wine, beverage, chemical industry emulsion and coating is also extremely to be closed in industrial production
The problem of note.
Traditional particulate separation filter core uses the in-depth filtration materials such as non-woven fabrics, activated carbon, sintering ceramics.Due to by material
Often there is pore size inequality in the property limitation of material sandwich construction itself, in-depth filtration material, it is difficult to obtain accurately filtering
Precision；Need in the presence of external force during filtering, particulate matter is intercepted by material layers barrier, filtration resistance is big, filtering
Efficiency is low, and energy consumption is big, and filter element replacing is frequent；Further, since the porous of material labyrinth-like, has stronger water absorbing capacity, material
Material is usually under dampness, easily the harmful substance such as breed bacteria, parasite.Therefore, the secondary pollution pole of such material
To be serious.
How to extend the service life of filter core, improve filtering accuracy and efficiency, maximumlly reduce the secondary pollution of filter core,
And then filter plant and use cost are reduced, ensure the health and safety of user, be the problem that we concentrate on studies.
Nucleopore membranes are a kind of hole density height, the high-precision individual layer precision mistake that aperture is homogeneous, pass is controllable, hole body is evenly distributed
Filter material material, hole density is up to 104~1012/cm2, pore size can control arbitrarily at 10 nanometers~50 microns.If with particulate matter
Particle diameter define harmful substance size in liquid, the particle diameter of bacterium typically 7~8 microns, the particle diameter of virus typically 0.3~
0.4 micron, substantially belong to minimum grain size class.Therefore effectively set nucleopore film filtering material pore size, just can by bacterium, virus and
The filtering completely of other particulate matters is clean.If the high-absorption materials such as binding activity charcoal, biology enzyme to organic matter, heavy metal ion,
The high absorption capacity of peculiar smell, just can effectively solve the edible drink such as wine, beverage, and the particulate separation of chemical industry emulsion and coating is asked
Topic；Equally, the preposition processing for Drinking Water, sewage and industrial wastewater is up to good effect.
Although nucleopore membranes have the advantages of many other in-depth filtration materials can not substitute in liquid precise filtering,
It is that its less mechanical strength and poor pollutant carrying capacity will restrict it and in some high intensity application fields effectively use.Such as
Fruit carries out nucleopore membranes with the nonwoven cloth material with preferable mechanical strength and pollutant carrying capacity effectively compound, it will makes it in liquid
And field of air filtration plays an important role.
In the case of dead-end filtration, under the promotion of pressure differential, liquid and the particle less than filtering membrane aperture pass through micropore,
Particle more than filtering membrane aperture is trapped within filter membrane surface, is deposited on film surface, in this case, if only using nucleopore
Membrane filtration layer is filtered, and micropore is easily trapped thing and blocks and influence the life-span of filter membrane, therefore a kind of, it is necessary to pollutant carrying capacity
Strong filtering material first obstructs to larger particles, then carries out refined filtration with nucleopore membranes filter layer, so as to reach preferable filtering
Effect.
