Description

Technical Field

[0001] The utility model relates to the field of ceramic membrane filters, in particular to a membrane pollution prevention device for an inorganic ceramic membrane ultrafiltration clarification system. Background Art

[0002] Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes made from inorganic ceramic materials through a special process. Ceramic membranes are divided into tubular ceramic membranes and flat ceramic membranes. Please note that "CT membrane" is not an alternative name for ceramic membrane; the term is a misnomer used by non-professionals to describe the English abbreviation for ceramic membrane. Tubular ceramic membranes have densely packed micropores on their walls. Under pressure, the feed liquid flows inside or outside the membrane tube, allowing small molecules (or liquids) to permeate the membrane while large molecules (or solids) are retained by the membrane, thereby achieving separation, concentration, purification, and environmental protection. Flat ceramic membranes have densely packed micropores on their surfaces. The permeability varies depending on the molecular diameter of the permeating substance within a certain pore size range. The pressure difference across the membrane acts as the driving force. The membrane acts as the filtration medium. Under a certain pressure, when the feed liquid flows across the membrane surface, only water, inorganic salts, and small molecules are allowed to pass through the membrane, while large molecules such as suspended solids, glue, and microorganisms are prevented from passing through. Ceramic membranes have many advantages, such as high separation efficiency, stable effect, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high temperature resistance, pollution resistance, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, easy operation and maintenance, and long service life. They have been successfully used in many fields such as food, beverages, plant (drug) deep processing, biomedicine, fermentation, fine chemicals, etc., and can be used for separation, clarification, purification, concentration, sterilization, desalination, etc. in the process.

[0003] However, the existing inorganic ceramic membrane filters still have the following problems during use:

[0004] When existing inorganic ceramic membrane filters perform filtration operations, separate substances will interact with the membrane surface or inside the membrane pores of the inorganic ceramic membrane to cause adsorption and accumulation. Many pollutants adhere to the membrane pore walls, causing the membrane pores to be blocked, reducing the volume of the membrane pores, and the permeability decreases due to the narrowing of the membrane pores. Therefore, it is very necessary to use a membrane pollution prevention device involving an inorganic ceramic membrane ultrafiltration clarification system in the existing ceramic membrane filter field.
