Spiral wound membrane component and membrane processor adopting spiral wound membrane component

Abstract

The invention discloses a spiral wound membrane component and a membrane processor adopting the spiral wound membrane component. The spiral wound membrane component comprises a core tube, a membrane group and a sealing ring; a water producing flow channel is formed in the core tube; a first filling block which cannot block the water producing flow channel is arranged in the water producing flow channel, or the diameter of the cross section of the water producing flow channel is not greater than 5 mm; the membrane group is wound on the core tube; the sealing ring is arranged on the outside of the membrane group in a sleeving manner. According to the spiral wound membrane component disclosed by the invention, the first filling block is arranged in the water producing flow channel, or the diameter of the cross section of the water producing flow channel is not greater than 5 mm. Compared with the prior art, the volume of the water producing flow channel can be reduced remarkably, so that the water storage amount of the water producing flow channel can be effectively reduced; when a water purifier performs re-purification, the re-purification time can be reduced remarkably; the time required for a re-purification process before the water purifier is started to make water can be reduced remarkably.

Description

technical field [0001] The invention relates to a roll-type membrane module and a membrane processor using the roll-type membrane module. Background technique [0002] The membrane processor using the roll-type membrane module is a filter device that passes the filtrate through the roll-type membrane module under a certain pressure to remove various pollutants such as particles and bacteria in the water. It is also commonly called a filter element, such as reverse osmosis. filter element, nanofiltration filter element, ultrafiltration filter element. The coiled membrane module includes a core tube, a diaphragm group and a sealing ring; the core tube is provided with a water flow channel; the diaphragm group is wound on the core tube, and the sealing ring is set on the outside of the diaphragm group and connected to the membrane The inner wall of the processor casing is sealed and connected. When the coiled membrane module is running and after running, the product water cha...

Problems solved by technology

However, the cross-sectional diameter of the water production flow channel in the core tube of the existing spiral membrane module is about 10 mm, which takes up a relatively large space, that is, the water storage in the water production flow channel is relatively large, which causes the water purifier to start. The previous repurification process of the water takes longer and wastes more energy
