Title:
RAW-WATER PARTIAL FLOW GUIDE MEMBRANE ELEMENT AND FILTER ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/246741
Kind Code:
A1
Abstract:
Disclosed are a raw-water partial flow guide membrane element and a filter element, which relate to the field of water purification. The membrane element is used for cross flow filtration and comprises at least one membrane bag and raw-water flow guide nets arranged on inner side surfaces of membranes, wherein each membrane bag is provided with two opposite membranes, a raw-water flow channel is formed on an inner side surface of the membrane and is in communication with a raw-water inlet and a concentrated-water outlet of the membrane bag, and the concentrated-water outlet is located at the position of a first short side; a pure-water flow channel is formed on an outer side surface of the membrane; and the raw-water flow guide net is approximately equal to a second short side in a widthwise direction, the raw-water flow guide net is locally arranged in a lengthwise direction, and the raw-water flow guide net covers a raw-water inlet area. The water flow speed at a raw-water-side concentrated water end is automatically increased, such that blockage is avoided, and the anti-pollution capacity is strong. The longer membrane bag can be arranged in the same space, such that the water purification capacity is also significantly improved.
