Plate type and two surface filtration type micro-porous ceramic structure

Abstract

A plate-shaped millipore ceramic structure with dual filtering surfaces for cleaning water by high filtering throughput is prepared through making a reticular porous plate with the material able to be converted to gas at high temp putting it in the ceramic blank, and high-temp calcining to gasify said plate to form the reticular channels.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a plate-like microporous ceramic structure for filtering on both sides. Background technique [0002] Microporous ceramics used as filter materials in water treatment equipment have many advantages, such as low cost, easy cleaning after clogging, basically all flow after cleaning, no decrease in filtration accuracy, and stable water quality throughout the filtration process. Wait, so it's already widely used. [0003] Microporous ceramics used in water treatment equipment are generally made into plates, tubes or hemispheres. When filtering, the water enters from one side and flows out from the other side, and the pollutants are blocked on the surface of the incoming water, and deposit or accumulate on the surface to form a filter cake. As the filtration process proceeds, the thickness of the filter cake becomes thicker and the filtration resistance increase...

Problems solved by technology

[0005] For plate-shaped microporous ceramics, one method is to directly increase the plate area, such as increasing the diameter of circular plate-shaped microporous ceramics. On the one hand, the manufacturing yield of microporous ceramic plates with too large diameter is low, and installation and use are difficult. It is easy to be damaged. On the other hand, a large diameter means a large volume of the equipment, so the method of directly increasing the area of ​​the microporous ceramic plate will increase the manufacturing cost of the equipment quickly; another method is to connect the two via a connecting partition. A piece of microporous ceramics is stuck together, and the upper and lower sides of the outer circumference of the connecting partition are respectively sealed and connected with the circular microporous ceramics. Sealed connection, such as the microporous ceramic filter element of Chinese patent water purifier (patent application number is 200520000553.3) discloses such a kind of microporous ceramic filter element structure

The size of this structure is relatively compact, and the flow rate can be increased significantly under the premise of a small increase in volume. However, the structure of this ceramic component is relatively complicated, the reliability is reduced, and the production cost is high.
