| titleOfInvention | Spiral wound type reverse osmosis membrane and method for cleaning same, and water purifier using spiral wound type reverse osmosis membrane |
| abstract | The invention provides a spiral wound type reverse osmosis membrane which comprises a center water collection pipe, water feeding flow guide cloth, water production flow guide cloth and a plurality of membrane components, wherein the membrane components comprise a pair of separation membranes; the water production flow guide cloth is positioned between the separation membranes to form a water production runner; three sides of each membrane component are sealed, and the fourth side of each membrane component can be opened to enable permeated water to leave; the water feeding flow guide cloth is arranged on one membrane of the membrane components to form a water feeding runner; the plurality of membrane components are wound around the center water collection pipe; the center water collection pipe comprises a penetration hole for collecting the permeated water from the membrane components; raw water enters the water feeding runner from one end of the water feeding runner; part of the raw water is filtered by the separation membranes to produce pure water; the pure water enters the center water collection pipe along the water production flow guide cloth; the residual non-filtered concentrated water flows out of the other end of the water feeding runner along the water feeding flow guide cloth. The spiral wound type reverse osmosis membrane also comprises an axial water feeding pipe provided with a plurality of small holes; the closer the small holes are to a condensed water outlet, the larger the diameters of the small holes are. |
