Description

Technical Field

[0001] The utility model belongs to the technical field of water purification equipment, in particular to a double-outlet pipe filter based on a W-shaped inorganic ceramic membrane. Background Art

[0002] The water purification and filtration equipment currently on the market all use a filter membrane assembly in combination with a rectangular water tank. The rectangular water tank serves as the outer shell, and the filter is large in size, which does not utilize the miniaturized water purification scenario. In addition, the filter membrane assembly of the current water purification and filtration equipment usually uses a flat inorganic ceramic membrane, which has a small membrane flux and a small water output. Therefore, most of the rectangular water tanks have a single-sided water outlet. In short, the water purification and filtration equipment currently on the market is not only large in size, but also has a small water output, and needs further optimization and development.

[0003] With the development of inorganic ceramic membranes, W-type inorganic ceramic membranes have been gradually developed and applied. Due to its unique corrugated membrane surface, the effective membrane area of ​​W-type inorganic ceramic membranes can reach twice the effective membrane area of ​​flat inorganic ceramic membranes, with greater membrane flux and greater water production. Patent CN219631029U discloses a pressure-bearing flat membrane water purification device, which also uses a W-type inorganic ceramic membrane, but it still uses a rectangular water tank as the outer shell. The volume of the water purification device is large, and it still has a single-side water outlet, and the water output is small. In order to further give play to the advantages of the W-type inorganic ceramic membrane, our company has developed a double-outlet pipe filter based on the W-type inorganic ceramic membrane, which not only has a large water output, but also a small volume, and has great practical value.
