Description

Technical Field

[0001] The utility model belongs to the technical field of reversely washable ultrafiltration membranes, and particularly relates to a reversely washable ultrafiltration membrane module. Background Art

[0002] The reversely washable ultrafiltration membrane is a water purification treatment technology that uses a hollow fiber membrane with micropores on the tube wall as a filtration medium and pressure as a driving force. Ultrafiltration allows the water to be treated to pass through the hollow fiber membrane at a certain flow rate by the action of external pressure. The micropores of the hollow fiber membrane only allow water molecules and molecules or particles smaller than 0.1 micrometer to pass through, while large-sized substance molecules or particles such as bacteria, colloids, particulate matters, and organic macromolecules larger than the micropores are intercepted, thereby purifying the water.

[0003] In the use process of the existing reversely washable ultrafiltration membrane module, it needs to be connected to other water inlet pipes. The connection between pipes usually adopts the way of pipe docking. Leakage is likely to occur at the docking part between pipes. When leakage occurs, adding a sealing gasket is usually used to relieve the leakage. However, most of the sizes of the sealing gaskets are fixed, which easily leads to gaps still existing at the pipe connection, affecting the filtration effect of the device. Therefore, we need to upgrade and transform on the basis of the existing technology. Content of the Utility Model
