Abstract

The invention provides a high-precision low-flux micro-porous ceramic pipe which is made of two materials with obviously different filtration precision; the water inlet surface of the micro-porous ceramic pipe is provided with a thin filter layer which is made of the material with high filtration precision and other parts thereof are made of materials with extremely low filtration precision. The high-precision large-flux micro-porous ceramic pipe of the invention is mainly used for filtrating drinking water and also for filtrating similar sanitary liquid. Compared with the prior art, the high-precision low-flux micro-porous ceramic pipe has the advantages of thin filtering layer and small water filtration resistance, improves the flux of the filtration water without reducing the filtration precision, thus leading the filter equipments to be designed to have small volume and low cost.

Description

Technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a high-precision large-flow microporous ceramic tube. Background technique [0002] The microporous ceramic used as the filter material in water treatment equipment has many advantages, such as low cost, easy cleaning after clogging, and the flow rate is basically restored after cleaning, the filtration accuracy does not decrease, and the water quality can be kept stable throughout the filtration process. Wait, so it has been widely used. [0003] Microporous ceramics used in water treatment equipment are generally made of plate, tube or hemispherical shape. During filtration, the water flow enters from one side and flows out from the other side. The contaminants are blocked on the side surface of the inlet water, and are deposited or accumulated on the surface to form a filter cake. As the filtration process progresses, the thickness of the filter cake becomes th...
