Description

Microporous filter
The utility model relates to a kind of millipore filter that industries such as electronics, medicine, electric power, fine chemistry industry prepare industries such as high purity water, recovered steam condensed water and food, beverage, oil, bioengineering that is used for.
The common millipore filter of China adopts backward static filtering mode mostly, this filter type very easily forms filter cake in cartridge surface, increase filtration resistance (in fact the filtration resistance of filter cake is the several times of filter element filtering resistance), reduce filtration flux, the regeneration period is very short.
The existing filter of China mostly adopts the filter material of fibrous matter as filter core, utilizes the suction-operated of fiber and the barrier effect of decussating fibers to stop seeing through of solia particle, requires the fiber filtering layer that certain thickness (being not less than 8mm) need be arranged.Though fiber can stop solia particle to see through, the particulate that enters the fiber filtering layer also is difficult for the backwash blowback and comes out, and brings difficulty for the regeneration of filter core.Make filter material as the employing cotton fiber simultaneously, not acid and alkali-resistance, organic corrosion, very easily breed bacteria; Adopt macromolecular material (as polyethylene, polypropylene, polypropylene fine etc.) to make filter material, same backwash pulse cleaning difficulty and heatproof not can only used below 60 ℃, can not utilize modal steam disinfection method.Will to accomplish to filter the following particulate of 0.5 μ m be very difficult to fibrous filter in addition, and the life-span of fabric filter element is also short, needs often to change.Fabric filter element withstand voltage general all below 0.45mpa can not adopt that high pressure is powerful to be filtered.In addition, also useful ceramic post sintering is as filter core, but crisp because of its property, flux is less, and range of application is restricted.
In view of above reason, the purpose of this utility model is in order to provide a kind of rate of filtration height, the millipore filter that the regeneration period is long.Another purpose of the present utility model is in order to provide a kind of not only rate of filtration height, regeneration period long, and high temperature resistant, high strength, long millipore filter of life-span.
Tank body is arranged in the utility model, it is characterized in that the intake chamber that contains import, circulation port, sewage draining exit is arranged in the tank body, the liquid outtake chamber that contains outlet, several or dozens of filter core, cavity is arranged in the filter core, the micropore (referring to Fig. 1, Fig. 8) that communicates with cavity is arranged on the element wall, adopt the dynamic filtration mode, can make the filtration flux of filter core stable for a long time, prolong the regeneration period.
Above-mentioned filter core adopts the metal alloy powders sintering to form, and can add various auxiliary agents (as pore creating material etc.) in Ni alloy powder or powder of stainless steel, and sintering forms behind isostatic compaction.
Have a support plate on the above-mentioned tank body at least, filter core is loaded on (referring to Fig. 1, Fig. 8) on the support plate.
The end that above-mentioned filter core places intake chamber and is arranged in intake chamber is that closed is and cavity on it communicates with liquid outtake chamber (referring to Fig. 1).
Support plate on the above-mentioned tank body is two, epicoele that contains import and the cavity of resorption that communicates with epicoele are arranged in the intake chamber, liquid outtake chamber is positioned between two support plates, filter core places liquid outtake chamber and two ends to be connected on the support plate, cavity on the filter core communicates with upper and lower cavity in the intake chamber respectively, and being positioned at import department in intake chamber has flow distribution plate (referring to Fig. 8).
The import department of above-mentioned intake chamber has and the tangent entrance sleeve that is connected of tank body (referring to Fig. 4), can form eddy current in intake chamber, improves the rate of filtration.
Be positioned at tank body import department in the above-mentioned tank body deflector (referring to Fig. 4) is arranged.
During the work of the utility model millipore filter (referring to Fig. 1), filter stoste and tangentially enter intake chamber through pipeline from the import on the tank body by the water pump pressurization, and through the deflector water conservancy diversion.Filtering stoste is the mixture (colloid, bacterium, larger molecular organics etc. all can be thought solid) of liquid-solid two-phase, under certain pressure effect, force the filter core that by metal alloy powders sintering form of this liquid-solid two-phase mixture by the band micropore, solia particle is retained on the filter core, clear liquid then enters the filter core inner chamber by the crooked micropore on the element wall and enters liquid outtake chamber, is discharged by outlet again.The partial concentration stoste that the feed liquor of top tangential direction and bottom circulation port are discharged makes the interior stoste of filter that a kind of vortex flow be arranged, and takes away the part solia particle on the element wall, thereby reaches the purpose that higher speed filters.
As the utility model employing structure as shown in Figure 8, filter stoste when then working and after flow distribution plate distributes, enter intake chamber's epicoele from the import on the tank body through pipeline by the water pump pressurization, by adjusting the flow of circulation port, make stoste flow through the cavity of filter core with higher flow velocity, clear liquid then enters in the liquid outtake chamber by the crooked micropore on the element wall and is discharged by outlet, and the stoste that concentrates is discharged by circulation port, returns former liquid pool, take away the solia particle on the chimney filter wall simultaneously, and reach the purpose of high-rate fitration.
Compare with existing filter, the utlity model has following advantage:
1, owing to adopted the dynamic filtration mode, the solia particle concentration of cartridge surface is not high, is difficult at surface deposition, and the filtration flux of filter core is stable for a long time, and the regeneration period of filter prolongs at double;
2, filter disc adopts the alloy powder sintering to form, and has improved the temperature and pressure scope of application greatly, and maximum operating temperature can reach hundreds of degree, and maximum working pressure is 1.5Mpa; Adopting Ni alloy powder or powder of stainless steel is the burn into intensity height of substrate forming thereby energy acid and alkali resistance, so the filter core long service life; Withstand voltage because of it up to 1.5Mpa, can adopt the powerful filtration of high pressure.
3, because the filter core that has adopted the alloy powder sintering to form, cartridge surface is bright and clean, tube wall is thin (about about 2mm), acid-alkali-corrosive-resisting, easy to loading and unloading, so regeneration is easily, reliably, except that renovation process such as common backwash, blowback, airblasting, but also mechanical cleaning, in 16~20%NaOH or 15%HNO3 solution, boil method such as calcination regeneration in high temperature gas flow, regeneration thoroughly can recover the flux more than 95%;
4, can adopt multiple sterilizing methods, available high-temperature vapour sterilization, routine disinfection solution such as also available 1~2% formaldehyde;
5, filter core adopts the alloy powder sintering to form, and the alloy powder epigranular, specification is many, waits static pressure, sintering process very ripe, so the micropore size of filter core is even, distribution concentration filter precision is far above general fabric filter element.Simultaneously,, can make the micropore of various diameters easily, satisfy the different requirements of filtering by selecting different granularities and different prescriptions;
6, applied widely: be applicable to remove degerm, the purification filtering and the clarification filtration of particulate, microorganism, micron order and sub-micron grade particle, be widely used in industries such as industries such as electronics, medicine, electric power, fine chemistry industry prepare high purity water, reclaim steam condensed water and food, beverage, oil, bioengineering.
