Description
Technical field
The present invention relates to a kind of resource filtering single-purpose filtering element, be specifically related to the single-purpose filtering element of filter solid contaminants and liquid impurities.
Background technology
Microfiltration membranes account for U.S., day, the European whole film market share more than 50%, be widely used in the separation of fluid with refining, waste water filtering process also reclaims useful component, zero discharge of industrial waste water, useless (dirt) water handling reclamation (membrane bioreactor, MBR) of activated sludge embrane method etc.Be mainly used in drinking water treatment abroad, domestic, be mainly used in the wastewater treatment of industrial circle, reuse.In addition, the pre-treatment as counter-infiltration is also extensively admitted, the bi-membrane method technology of such as micro-filtration/counter-infiltration combination, and Treatment of Industrial Water at home is particularly applied in electric power, chemical industry, automobile and other industries more.The application of current microfiltration membranes relates generally to microorganism separation in microelectronic water treatment, food and medicine field, clarification, purifying, concentrated, the electrophoretic painting of machinery manufacturing industry, printing and dyeing chemical industry, environmental protection etc.
Micro-filtration filter is as follows according to several kinds that textural classification is common:
One, melt-blown filter commonly use melt-blown filter by polypropylene superfine fiber hot melt tangle make.Fiber is randomly formed three-dimensional micropore structure in space, and micropore size, along filtrate flow to distribution gradient, integrates surface, deep layer, secondary filter, can retain the solid impurity of different-grain diameter.Two, Wire-wound filter core to be wrapped on stephanoporate framework refining by the textile fabric yarn precise with good strainability.Its thread material has polypropylene fiber, acrylic fiber, degreasing cotton fiber etc.By controlling the winding elasticity of yarn and rare density during winding, the filter core of different accuracy can be made, effectively can remove the suspension, granule foreign etc. of various liquid, have higher filter effect to various liquid.Three, collapsible micropore filter element is commonly used collapsible micropore filter element and is adopted polypropylene (Polypropylene) non-woven fabrics, nylon (Nylon), polytetrafluoroethylene (PTFE) (PTFE), with the secondary filter device that polyether sulfone (PES) miillpore filter etc. is made into for filter medium, there is volume little, filter area is large, precision advantages of higher.This type of filter core is filter configuration the most superior at present.Filtering accuracy scope can from 0.1 μm to 60 μm.For asking the minimum leachable of filter core, end cover of filter element sealing and overall structure connect, and generally all adopt hot melt adhesion.Filter core joint is three kinds of international patterns: 222 joints, 226 joints, flat mouth.Product all passes through strict complete test before dispatching from the factory, to guarantee the stable performance of product.Four, active carbon filter core active carbon filter core product has two large classes:
Compression-type active carbon filter core;
Bulk type active carbon filter core.
1, compression-type active carbon filter core adopts the coal mass active carbon of gel powder with high adsorptive and cocoanut active charcoal as filtering material, in addition the adhesive sintering compression molding of food-grade.Be wrapped in the non-woven fabrics that one deck has protective effect inside and outside extruded activated carbon filter core respectively, guarantee that charcoal core itself not easily drops powdered carbon and entering in the filtrate of downstream.Soft nitrile rubber sealing gasket is equipped with at active carbon charcoal core two ends, makes charcoal core load chimney filter and has good sealing.
2, required activated carbon granule loads in special plastic casing by bulk type active carbon filter core; with welding equipment, end cap is welded on the both ends of the surface of housing; the two ends of housing are placed with the non-woven fabrics filter disc of protective effect respectively, guarantee that charcoal core can not drop powdered carbon and entering in the filtrate of downstream in use.Five, resin filter element resin is a kind of porous, insolubility ion exchange material.In water softening device, resin filter element is built with millions upon millions of fine baton rounds (pearl), and all beads all contain the negative electrical charge cation exchange groups of many absorption cations.When resin is in primordial condition, these charge-exchange groups are occupied by positively charged ion (such as sodium ion).When calcium and magnesium ion are through resin storage tank, they can contact with resin beads, thus the sodium ion in cation exchange groups.The preferential Binding protein of resin is compared with the cation of forceful electric power lotus, and the charge ratio sodium ion of calcium and magnesium ion is strong.Then replacement sodium cation passes downwardly through resin, and " bed, outflow water softening device, such water softening device has just sent " soft " water.Finally, all resins exchange positions are all occupied by calcium and magnesium, then can not carry out work.Six, titanium rod filter core titanium rod filter core has corrosion-resistant, and high temperature resistant, intensity is large, and filtering accuracy is good, and easily regeneration waits excellent properties; Titanium rod filter core is formed through shaping, high temperature sintering by titanium valve, therefore surface particles difficult drop-off; Serviceability temperature can reach 500 ~ 600 DEG C in atmosphere; Be applicable to the filtration of various Korrosionsmedium, such as: the filtration of the chloride solution such as hydrochloric acid, sulfuric acid, hydroxide, seawater, chloroazotic acid and iron, copper, sodium.It also has excellent mechanical performance, can carry out cutting, the machined such as welding, and compressive resistance is large, and interior pressure breakdown strength is up to more than 2MPa, even if work at high temperature under high pressure, aperture also can not deform.And renovation process is simple, reusable after regeneration.The principle of seven, RO reverse osmosis filter core reverse osmosis (Reverse Osmosis) is the one end in feed water, applies the pressure larger than naturally osmotic pressure, makes hydrone by the high side's reverse osmosis of concentration to the low side of concentration.Aperture due to reverse osmosis membrane is far smaller than microorganism and bacterium, therefore various virus, bacterium, metal ion, solid dissolvable thing, Organic Pollutants, chlorion etc. cannot pass through reverse osmosis membrane, thus reach the object of water demineralization filtration.Eight, stainless steel filter core stainless steel filter core similar titanium rod filter core: there is good strainability.Its corrosion resistance, heat resistance, resistance to pressure, wearability are good; And stainless steel filter core is suitable for low temperature, hot environment; Can also reuse after cleaning, avoid regular replacing.
Above-mentioned filter membrane can be classified two classes substantially, and a class is the purification dechlorination filter core of solid impurity, and another kind of is liquid impurities process filter core.Shortcoming in the process of process, can only process a kind of impurity, can not settle at one go compound material to be clean, process field is narrower.As Chinese patent 201220676812.4 discloses a kind of miillpore filter folding type filter element, by filtering medium layer, inner support cylinder and outer support cylinder are formed, filtering medium layer is folded into fin back wall around on the excircle of inner support cylinder, described filtering medium layer is by a miillpore filter layer and two protective layers are superimposed forms, two described protective layers are separately positioned on the both sides of described miillpore filter layer, inner support cylinder and the upper end of outer support cylinder be fixedly installed a upper end cover, the lower end of inner support cylinder and outer support cylinder is fixedly installed a bottom end cover, its advantage is: arrange miillpore filter in folding type filter element, and set up protection filter membrane in its both sides, increase the pollutant holding capability of filter core, its shortcoming is that the filter effect for solid-liquid phase composite impurity is not obvious.And for example: Chinese patent 201020255541.6 discloses a kind of filter core, comprise a pp chimney filter, the inwall of the one pp chimney filter is provided with the two pp chimney filter identical with a pp chimney filter length, activated carbon filtration body is filled with between one PP chimney filter and the 2nd pp chimney filter, the top of the one pp chimney filter and the 2nd pp chimney filter and bottom are respectively equipped with the first end cap and the second end cap, its advantage is: first can filter large material by PP pipe, secondly can some heavy metals of adsorption filtration and organic matter by middle activated carbon filtration body, improve filter effect, its shortcoming is: the filter effect for short grained impurity and solid-liquid phase composite impurity thereof is not obvious.
Although commercially available binodal filter core has merged both shortcomings, carried out solid-liquid integrated treatment, it has been connected simply, can only doing the comparatively thick product required obviously, reaching high-quality removal of impurity requirement to requiring higher product to have no idea.As: Chinese patent 200920163237.6 discloses a kind of double-joint filter element device, comprises upper cover, adsorption section and lower cover, is filled with adsorption layer in adsorption section, and the adsorption section filter house through with it is connected, and is provided with filter course in filter house; Adsorption section tentatively remove objectionable after filter through filtering layer again, filtration effect increases, shortcoming is: adsorption section is simply connected up and down with filter house, and adsorb or filter operation all only independent the carrying out of filter house and adsorption section, the product high to removal of impurities quality requirement is inapplicable.
