Definitions
- the invention relates to a filtration device for filtering liquids.
- a filtration device for filtering liquids.
- Bacteria and viruses can be removed by appropriate chemical treatment of the water.
- such devices are relatively maintenance-intensive since the chemicals have to be refilled.
- the water is contaminated with chemicals.
- Filters are used, for example, to separate oil-water emulsions during machining, for clarifying beer, for gas purification, for gas separation or for separating liquid-solid mixtures.
- the object of the present invention is to provide a compact and easy-to-use filtration device with a good filter effect, with which substances, in particular bacteria and / or viruses, can be removed from a liquid.
- a filtration device comprising a pressure-resistant housing with a liquid inlet opening and a filtrate outlet opening, into which a collecting duct opens, to which at least one filter element designed as a flat membrane is connected in a pressure-tight manner.
- the liquid to be filtered is passed through the liquid inlet opening to which a feed line can be connected. fed to the container.
- the liquid in the container is under pressure and is pressed through the flat membrane due to the pressure, there being a pressure difference between the outside of the flat membrane and its interior.
- the housing is suitable for absorbing the pressures that occur during filtering and is therefore pressure stable.
- Various shapes are conceivable for the housing, for example a cuboid shape or a cylindrical shape.
- the flat membrane can be designed as a porous functional layer, from the interior of which the filtrate is removed and which can be flowed against on almost all sides by the liquid to be filtered.
- the flat membrane can comprise a fine-pored filtering functional layer which is held on a coarser-pored carrier layer, a so-called substrate.
- the functional and carrier layers are preferably inorganic layers and are therefore wear-resistant, temperature-stable and largely chemically inert.
- a flat membrane that can be flowed on almost all sides, from the interior of which the filtrate can be removed, has a favorable ratio of membrane area to volume of the membrane. This results in good efficiency.
- the filtrate is fed from the inside of the flat membrane to the collecting channel and can be removed or extracted via the outlet opening.
- the filter element can be connected directly or indirectly to the collecting duct via additional constructions, the connection of the filter element to the collecting duct always being pressure-tight, so that no unfiltered liquid gets into the collecting duct.
- a line with a valve for example a water tap, can be connected to the outlet opening.
- the functional layer can be selected so that its pores are smaller than the substances to be filtered out.
- Liquid to be filtered in the sense of the invention is understood to mean a dispersant with gaseous, liquid or solid substances contained therein, in particular solutions, hydrosols, bladder systems, emulsions and suspensions.
- a plurality of filter elements are connected to the collecting duct one behind the other and at a distance from one another.
- the filter area can be increased with a small footprint. Because of the spaced arrangement, liquid can be pressed into the membrane on all sides, in particular from the two large sides. This is particularly advantageous if the inside of the flat membrane is designed as a carrier layer which has a functional layer on all sides on the outer surface. The filtrate can therefore be pressed into the membrane over almost the entire free outer surface and removed from the inside of the flat membrane.
- a sedimentation space is provided below the filter element.
- sediments can be deposited below the filter element, which are at least spaced from the housing base by the diameter of the collecting channel. The blockage of the filter surfaces is prevented or slowed down.
- the sedimentation space has a closable outlet opening. Deposited sediments can be removed.
- the filter elements and the housing can be cleaned or rinsed.
- the housing can be made of plastic, ceramic or stainless steel.
- the advantage of the plastic housing is its low weight and good corrosion resistance, that of the stainless steel housing in its pressure stability.
- the filter elements can be removed and cleaned particularly easily if the housing has a cleaning opening. It is understood that because of the pressurization of the liquid to be filtered, the cleaning opening is pressure-tight can be closed, for example by a screw-on cover. Alternatively, the housing can also be constructed in several parts, so that the housing can be disassembled for cleaning.
- a pump can be assigned to the liquid inlet opening or to the housing.
- a pressure of 1 to 7 bar may be sufficient for certain applications.
- An additional pressurization of the liquid to be filtered may be necessary, in particular in the case of functional layers with a small pore size, in order to ensure the functioning of the filtration device.
- a filtration device with a plurality of filter elements designed as flat membranes which are spaced apart from one another. and the interiors of which are pressure-tightly connected to a collecting duct, essentially the entire outer surface of each filter element being designed as a filter surface.
- a filtration device can, for example, be immersed in a basin containing a liquid to be filtered, the hydrostatic pressure pressing the liquid into the membranes.
- the immersed filter elements are completely surrounded by the liquid except for a few places, for example the connection point with the collecting channel.
- the outer surface of each filter element is therefore available as a filter surface.
- the spaced apart arrangement also allows the filter elements to be cleaned by flowing air or ozone along the filter surfaces. The filter cake that accumulates can be removed particularly easily by this measure.

- Each filter element half can have a carrier layer and a functional layer or only one functional layer.
- the carrier layer and functional layer can be obtained from green layers, layers which contain ceramic particles but are not yet sintered being called green layers.
- the layers are green layers, the carrier layers of the filter element halves carrying a functional layer can be laminated together before sintering. After sintering, a filter element is obtained which has fine-pored filter surfaces on the outside and a coarser-pored structure on the inside, through which the filtrate can be removed.
- the filter halves consist exclusively of a functional layer, they can also be laminated as green layers. However, the filter element halves or the entire filter element can also be produced by extrusion.
- the ceramic materials used in the green layers are preferably of metal (mixed) oxides and carbides, nitrides, borides, silicides and carbonitrides of metals and derived non-metals.
- metal (mixed) oxides and carbides nitrides, borides, silicides and carbonitrides of metals and derived non-metals.
- this are A1 2 0 3 , partially and fully stabilized Zr0 2 , mullite, cordierite, perovskite, ⁇ pinelle, for example BaTi0 3 , PZT, PLZT, and SiC, Si 3 N, B 4 C, BN, MoSi 2 , TiB 2 , TiN, TiC. And Ti (C, N). It goes without saying that this list is not exhaustive. Of course, mixtures of oxides or non-oxides and mixtures of oxides and non-oxides can also be used.
- the filtrate discharge channels can be implemented particularly simply if, at least in one filter element half, channels are formed on the surface facing the other filter element half.
- the channels are preferably formed by milling the green support layer '. Channels can only be provided in one or both support layers. If the backing layers are laminated, the channels can be staggered or opposed. If they face each other, channels with a large cross-section are formed in the filter element.
- any filter element geometries can be realized if the filter element halves are each made by casting a green layer with subsequent sintering.
- the filter elements can be circular, square or rectangular, for example.
- miniaturized filter arrangements can be realized in which a filter area of 0.1 m 2 is realized by five filter elements.
- very large-area filter elements for example for seawater desalination, can be produced by film casting.
- the filtration elements can be up to 0.5 m wide and cut to any length. This means that filter modules with a filter area of, for example, 45 m 2 can be produced from several filter elements.
- the filter element is sealed, plugged in or glued into the collecting duct.
- the collecting duct in one piece with the filter element or elements in order to achieve a good seal, in particular a pressure-resistant seal between the collecting duct and the filter elements.
- an O-ring is provided for sealing. This measure enables an effective and simple . Seal.
- the filter elements have pores in a functional layer with a pore size of 300 nm.
- the pore size used depends on the area of application of the filtration device.
