Abstract
The utility model discloses a compound type efficient microporous membrane ceramic filter which comprises a filter body, wherein the filter body is an entirety formed by a filter working layer (1) and an overflow supporting layer (2) via high-temperature firing; the filter working layer has a micro membrane shaped pore structure of 10-15 microns; and the overflow supporting layer has a microporous structure of 50-100 microns. The compound type efficient microporous membrane ceramic filter is suitable for inorganic sewage purification treatment equipment which is faintly acid, high in concentration and complicated in component, and has the advantages of good filter and purification effects, high filter efficiency, long cycle of operation, difficulty in blocking, easiness in cleaning and long service life.
Description
Technical field
The utility model relates to ceramic filter, especially relates to composite efficient microporous barrier ceramic filter.
Background technology
In existing environmental protection equipments such as water treatment, mostly adopt at present traditional inoranic membrane ceramic filter and traditional microporous ceramic filter, but in use there is following deficiency respectively in they: the one, and traditional inoranic membrane ceramic filter cost is too high, use regeneration backwash frequency height, service life is short, the operation and maintenance cost height; The 2nd, traditional microporous ceramic filter finely ground particles when filtering operation easily be penetrated into millipore filter inner form stop up, that the backwash difficulty is big, filter lost efficacy is fast.
The utility model content
The purpose of this utility model mainly is the above-mentioned deficiency that has overcome traditional inorganic membrane filtration device and millipore filter in the prior art, provide in a kind of inorganic wastewater purification apparatus that is applicable to faintly acid, high concentration, complicated component and used, not only filtration, purification is effective, the filter efficiency height, the cycle of operation is long, and be difficult for stopping up easy cleaning, the composite efficient microporous barrier ceramic filter of long service life.
The technical scheme that the technical problems to be solved in the utility model is taked is: composite efficient microporous barrier ceramic filter comprises filter body, described filter body is by filtering working lining and the overcurrent supporting layer is formed and the integral body that forms through high-temperature firing, described filtration working lining has 10-15 μ m mocromembrane shape aperture structure, and described overcurrent supporting layer has 50-100 μ m micropore shape structure.
For preventing that cracking and overcurrent uniformity from not appearring when the sintering in filter body, the overcurrent supporting layer is provided with medial launder, and described medial launder is square, also can be rectangle, circle etc.
The utility model mainly is accomplished by following technique measures, and described filtration working lining is mainly by SILICA FUME and AL
2O
3And the compound of a spot of pore former, lubricant and activating agent preparation is formed; Described overcurrent supporting layer mainly is made up of the compound of silica and pore former, binder making on a small quantity, two kinds of compounds successively add in the mould, divide two-layer composite laminate moulding, make the integral body of filter body again through high-temperature firing, filtering working lining is 10-15 μ m mocromembrane shape aperture structure (the mocromembrane hole is network structure), and the overcurrent supporting layer is a 50-100 μ m micropore shape structure (micropore is network structure).The membranaceous filter medium of micropore of this kind asymmetry network-like structure, by manyly vary in size, be evenly distributed, be interconnected, bridge arch shape opening road forms.When fluid passes through these opening roads, produce various physical effects during application, make suspended material, larger molecular organics matter, colloid shape material be held back the outer surface that is adsorbed on medium naturally, reach the purpose of mechanical grading filtration.The finely ground particles that the filter of this kind structure, filtration working lining can be held back 1-3 μ m is difficult for being penetrated into filter interior formation obstruction.Flux is big during the work of overcurrent supporting layer, resistance is little, be difficult for obstruction, backwash effect is good.
Described composite efficient microporous barrier ceramic filter is the MFAB type, and wherein MF represents inorganic matter, and A represents to filter working lining, and B represents the overcurrent supporting layer, and AB represents to filter two kinds of mix layered combinations of working lining and overcurrent supporting layer integral body of becoming of high-temperature firing again.
With the filtering ponds that MFAB composite efficient microporous barrier ceramic filter is dressed up as media pack, the filtering and purifying of filter and various filtered version, its key property function is as follows:
1, fine corrosion resistance, thermal shock resistance is good, mechanical strength height, not aging distortion, long service life.
2, do not pollute leachable, SS≤30mg/L in good filtration effect, precision height, the water outlet water.
3, be difficult for stopping up, the cycle of operation is long, and regeneration backwash effect good (about 1-3 years once) is that other conventional filtration devices are more than 100 times.
4, because its cycle of operation in service life is long, need not add any medicament, power manpower consumption spy is little, operation and maintenance cost is saved more than 70 than other filters.
The present invention has the excellent specific property function, can guarantee that this system and device for a long time, efficiently, safely, normally hangs down the expense operation.Can be widely used in the environmental wastewater processing of industries such as chemical industry, metallurgy, medicine, electric power, be the one preferred technique device of current energy-saving and emission-reduction.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
In the drawings, 1, filter working lining 2, overcurrent supporting layer 3, medial launder.
The specific embodiment
In Fig. 1 and Fig. 2, described composite efficient microporous barrier ceramic filter comprises filter body, filter body described in the present embodiment is square bulk, be of a size of 250 * 250 * 60mm, also can be the rectangle bulk, described filter body is by filtering working lining 1 and overcurrent supporting layer 2 is formed and the integral body that forms through 800-1200 ℃ of high-temperature firing, described filtration working lining has 10-15 μ m mocromembrane shape aperture structure, mocromembrane shape hole is net distribution, filtration work layer thickness is 3mm, overcurrent supporting layer thickness is 57mm, and described overcurrent supporting layer has 50-100 μ m micropore shape structure, and micropore is net distribution.The overcurrent supporting layer is provided with medial launder 3, and described medial launder is the square groove of 170 * 170 * 10mm, also can be rectangle, circular trough etc.Described filtration working lining is mainly by SILICA FUME and AL
2O
3And the compound of a spot of pore former, lubricant and activating agent preparation is made; Described overcurrent supporting layer is mainly made by the compound of silica and pore former, binder making on a small quantity, the various raw material mixing and ball milling that to prepare the overcurrent supporting layer are earlier made the overcurrent sludge mixed material and are put into mould, filtration sludge mixed material with the various raw material mixing and ball milling of preparation filtration working lining is seated on the overcurrent sludge mixed material again, divide two-layer composite laminate adhesion-molded, make the different base substrate of two-layer porosity, again this base substrate is formed composite efficient microporous barrier ceramic filter through the high-temperature firing cooling.
