Abstract
The utility model discloses earthenware slab film, comprise porous support layer and separating layer; Described porous support layer is tabular, is provided with the access opening of several axis in porous support layer; Described porous support layer surface is provided with one deck separating layer.The utility model forms the filtering micropore in suitable aperture at access opening, and the aperture of effective controlled filter micropore, improves the filtering accuracy to waste water, waste gas, and the writing board shape of earthenware slab film rinses conveniently, avoids waste to adapt to higher environmental requirement.
Description
Technical field
The utility model relates to ceramic membrane technology field, particularly earthenware slab film.
Background technology
Membrane science technical field Application and Development comparatively early be organic film, this film is easily prepared, easy shaping, functional, low price, has become most widely used microfiltration membranes type.But along with the development of membrane separation technique and application thereof, more and more higher requirement is proposed to the service condition of film, needs to develop extreme condition film solid-liquid separation system.
Inoranic membrane isolation technics is a kind of emerging efficient, accurate isolation technics, is that material science is intersected with mass transfer isolation technique and combined, high with separative efficiency, equipment is simple, the advantage such as easy to operate and energy-conservation, by every field extensive use.Inoranic membrane develops rapidly in recent decades, become the support technology of the industrial process technological progresses such as the energy, resource, environmental protection, metallurgy, light industry, chemical industry, petrochemical industry, biochemical industry, have broad application prospects, become the focus of countries in the world research in recent years, development and application, the development of membrane technology is more called as " the third time industrial revolution ".
Inorganic membrane technology application is by new high-tech industry new for formation one, and the international market annual growth of inorganic membrane product is 30%, accounts for 12% of whole membrane technology market, and still in rapid growth.China is using membrane technology one of 2 kinds of technology as chemical industry emphatically development, and taking off and the enhancing of people's environmental protection consciousness along with China's economy, will become the new period of China's inorganic membrane technology develop rapidly at the beginning of 21 century.
Ceramic membrane (ceramic membrane) is the one in inoranic membrane, belong to the solid film material in membrane separation technique, main using inorganic ceramic materials such as the aluminium oxide of different size, zirconia, titanium oxide and silica as supporter, form through surface coating, high-temperature firing.Ceramic membrane is mainly tubulose on the market, and it is low that it exists film loading density, and unit volume effective filtration area is little, and separative efficiency is low, rinses poor stability and causes the shortcomings such as waste.
Summary of the invention
The purpose of this utility model is the deficiency effectively overcoming above-mentioned technology, provides earthenware slab film, and the aperture of effective controlled filter micropore, improves the filtering accuracy to waste water, waste gas, avoids waste to adapt to higher environmental requirement.
The technical solution of the utility model is achieved in that and comprises porous support layer and separating layer; Described porous support layer is tabular, is provided with several access openings in porous support layer, the cross section of access opening at porous support layer up and down between two planes; Described porous support layer surface is provided with one deck separating layer.
The cross section of upper described access opening is circular or polygon.
The material of above-mentioned separating layer is alundum (Al2O3).
The aperture of above-mentioned access opening is 0.8 μm ~ 1 μm.
The beneficial effects of the utility model are: can the aperture of controlled filter micropore, improve filtering accuracy to waste water, waste gas, and the material adopted meets environmental requirement, the plate-like structure of earthenware slab film can high pressure washing, stability is high, cost-saving, be applicable to extensive use, compared with organic hollow film, it is high that earthenware slab film has film body intensity, drug resistance, heat resistance is strong, difficult pollution, the caducous advantage of pollutant.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
