Ceramic flat sheet membrane module and membrane stack

Abstract

The invention provides a ceramic flat sheet membrane module and a membrane stack in order to solve the problems that an existing ceramic flat sheet membrane module is large in size, complex in assembly structure and small in water yield, and the backwashing effect cannot be guaranteed. The module comprises a module main body, two rubber sealing pieces and a diaphragm; a cavity, a left sealing cavity and a right sealing cavity are formed in the module main body; the two sealing pieces are installed on the two side walls, corresponding to the two ends of the cavity in the length direction, of the module body in an embedded mode respectively. The multiple membranes are vertically arranged in the cavity in parallel in the length direction of the cavity. The two ends of each diaphragm in the length direction are water outlet ends; the water outlet ends are inserted into the corresponding sealing pieces and are attached to the sealing pieces in a sealed mode. According to the invention, materials are reduced, the cost is reduced, the assembly process is reduced, the assembly process is optimized, the assembly difficulty is reduced, the production efficiency is improved, the membrane function is fully exerted, and the operation is stable.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a ceramic flat membrane module and a membrane stack. Background technique [0002] Research on inorganic ceramic membranes began in the 1940s, and breakthroughs were made in the late 1980s. The research on inorganic ceramic membranes and separation technology in my country started relatively late, but developed rapidly. Because the inorganic ceramic membrane has a series of advantages such as high efficiency, high temperature resistance, reliable operation and good chemical stability, the prospect is very broad. [0003] The manufacturing method of ceramic flat membrane membrane group (commonly known as "membrane group") in the industry is as follows: [0004] Step 1, Membrane element processing: After the ceramic diaphragm is sintered at high temperature, select a qualified diaphragm and cut it in parallel at both ends according to the specified size, and put the two e...
