Abstract

The invention discloses a spiral rolling type reverse osmosis membrane element, a filter element and a reverse osmosis water purifier. The spiral rolling type reverse osmosis membrane element comprises a multi-blade reverse osmosis membrane set, a central tube set, a first end cover and a second end cover, wherein the central tube set comprises a pure water pipe and a plurality of wastewater pipes which are arranged at intervals; the wastewater pipes are distributed around the pure water pipe; each reverse osmosis membrane set is provided with a first part located in the central tube set and a second part located on the exterior of the central tube set; each wastewater pipe and the pure water pipe are separated by the first part of one reverse osmosis membrane set; multiple layers of membrane elements surrounding the periphery of the central tube set are formed by the second parts of the reverse osmosis membrane sets; the first end cover and the second end cover are respectively sleeved at the two ends of the central tube set and the multi-blade reverse osmosis membrane set; a pure water outlet and a wastewater outlet are arranged on the first end cover or the second end cover corresponding to the central tube set. According to the technical scheme provided by the invention, the recycling rate of raw water can be increased and high water-saving effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis water purification, in particular to a spiral-wound reverse osmosis membrane element, a filter element and a reverse osmosis water purifier. Background technique [0002] Spiral-wound reverse osmosis membrane elements, also known as spiral-wound reverse osmosis membrane elements, are commonly used elements in water treatment technology. Reverse osmosis selection membrane and diversion net. The central tube is connected with the two ends of the housing through connectors. When in use, the raw water enters the shell from one end of the shell, and under the action of pressure, part of it passes through the reverse osmosis membrane to form water with a lower concentration. After entering the central tube, it flows out from one or both ends of the central tube. This part of water can be called It is used as produced water or pure water; the other part flows out from the other end of the shell...
