Embodiment 1

[0029] Such as figure 1 As shown, it is a partially developed cross-sectional schematic diagram and a schematic diagram of water flow of a roll-type membrane module provided by the present invention. The coiled membrane assembly includes a core pipe 2 and a water purification membrane group. The water purification membrane group is wound on the core pipe 2 . The water purification membrane set includes a raw water diversion net 6 , two plate-shaped filter membranes 7 and a produced water diversion net 8 . Both sides of the permeated water diversion net 8 are adjacent to one side of the two plate-shaped filter membranes 7 , and the other sides of the two plate-shaped filter membranes 7 are adjacent to the raw water diversion net 6 . The water flow channel in the raw water diversion net 6 is the raw water flow channel, and the water flow channel in the produced water diversion net 8 is the produced water flow channel.

Abstract

The invention relates to the field of water purifying equipment and provides a spiral-wound membrane component and a filter element employing the same. The spiral-wound membrane component comprises a core tube and a water purification membrane group, wherein the water purification membrane group is wound around the core tube; the width of the edge, adjacent to the core tube side, of the water purification membrane group is larger than that of the edge, far away from the core tube side. Compared with the prior art, the spiral-wound membrane component and the filter element employing the same have the following benefits: when the thickness of a raw water guide net is set, the sectional area of a raw water channel in the spiral-wound membrane component is smaller or obviously smaller than that of the raw water channel of a traditional spiral-wound membrane component; when the raw water flow rates, the filtering areas and the water pressures on the raw water side are the same, the flow rate of raw water in the spiral-wound membrane component is much smaller, so that the flow rate of discharged concentrated water is also much smaller, and accordingly, the water-saving effect can be remarkably improved.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a roll-type membrane module and a filter element with the roll-type membrane module. Background technique [0002] The roll-type membrane assembly used in a large number of domestic and similar reverse osmosis water purifiers on the market includes a central water production pipe and a water purification diaphragm group; the water purification diaphragm group is wound on the central water production pipe; the water purification The membrane set includes a raw water diversion net, two plate-shaped filter membranes and a produced water diversion net; the raw water diversion net is located in the raw water flow channel formed between the inner surfaces of the two plate-shaped filter membranes; The water production diversion net is located in the water production flow channel formed between the outer surfaces of the two plate-shaped filter membranes, the water production f...
