Abstract

The invention discloses an inorganic ceramic membrane module. The inorganic ceramic membrane module comprises a filter cartridge, an upper end cover positioned at the upper end of the filter cartridgeand a lower end cover positioned at the lower end of the filter cartridge, and a liquid inlet is formed in the side surface of the lower end of the filter cartridge; a liquid outlet is formed in theside surface of the upper end of the filter cartridge; a water production port is formed in the upper end cover; a drain outlet is formed in the lower end cover; and the filter cartridge is a cylinder, an inorganic ceramic membrane element is arranged in the filter cartridge, the inorganic ceramic membrane element comprises a flat sheet membrane group positioned in the middle and an arc-shaped membrane positioned on the side surface of the flat sheet membrane group, and the length extending directions of the flat sheet membrane group and the arc-shaped membrane are the same as the extending direction of the filter cartridge. According to the inorganic ceramic membrane module, the plate type ceramic membrane can be applied to an ultrafiltration system, the advantages of the ceramic membraneare fully utilized, and the existing hollow fiber membrane module is replaced with low cost and large area, so that the aims of improving the stability of the system, reducing the operation cost andprolonging the operation life of equipment are fulfilled.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a combined inorganic flat ceramic ultrafiltration membrane module that can replace organic fiber membranes. Background technique [0002] At present, the membrane elements of ultrafiltration devices commonly used in the market use organic hollow fiber membranes. Due to the limitations of materials, they are limited in terms of pH range, temperature and service life when processing materials. Strict pretreatment is required and cleaning is difficult, greatly affected by temperature, high energy consumption in operation, and membrane filaments are easily broken. These ubiquitous problems restrict the development of the organic membrane product market. [0003] Inorganic ceramic membrane is a new type of high-efficiency porous membrane. It uses inorganic materials such as alumina, zirconia, titanium oxide and silicon oxide to make a porous structure support, and then prepare...
