Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Fig. 1 shows a cross-sectional view of a spiral wound membrane element according to an embodiment of the invention. As shown in fig. 1, the roll membrane element comprises a filter membrane 110, a first separation net 120 and a second separation net 130.
The first separation net 120 is disposed in the folded filter membrane 110 to form the membrane 100. Several membranes 100 are stacked in the same opening pattern of the filter membrane 110. The filter membrane 110 is folded in half, and the side opposite to the folding position 111 is the opening side of the filter membrane 110.
In one embodiment, the filter membrane 110 itself is "V" shaped, and the first screen 120 is disposed within the "V" shaped filter membrane 110.
In a particular embodiment, membrane sheets can also be taken as a feature, i.e. the roll membrane element comprises a membrane sheet 100 and a second spacer net 130. The membrane sheet 100 comprises a filter membrane 110 and a first spacer mesh 120.
A second spacer mesh 130 is disposed between adjacent membrane sheets 100; the second separation net 130 is hermetically bonded to one end of the outer side surface of the membrane 100 along the bending position 111 of the filter membrane 110 as a starting point, and extends to the other end of the bending position 111 of the filter membrane 110, so that a gap between the bending positions 111 of two filter membranes 110 on adjacent membranes 100 serves as an outlet of the second separation net 130. That is, the other side edges of the outer side surface of the membrane 100 except the bending position 111 are bonded and sealed with the second separation net 130 to form an envelope-shaped structure, and the side edge of the non-bonded bending position 111 is used as the outlet of the second separation net 130, so that the upper edge and the lower edge of the membrane 100 on the non-bonded side of the membrane 100 and the second separation net 130 are both the bending position 111, the solution can only enter the second separation net 130 through the filter membrane 110, and the solution in the second separation net 130 flows out through the outlet on the non-bonded side, thereby effectively preventing the raw water solution from directly entering the second separation net 130 to be mixed with the filtered produced water solution, increasing the filtering accuracy, increasing the filtering flow and improving the filtering efficiency.
In one embodiment, as shown in FIG. 2, the membranes 100 are stacked in a stepwise manner, starting from the fold location 111 of the filter membrane 110. That is, the first diaphragm 100 and the second diaphragm 100 are stacked with a certain displacement difference, and so on.
Further, the starting end of the second screen 130 is positioned between the folding positions 111 of the two filter membranes 110, so that the second screen 130 and the membrane sheets 100 are sequentially stacked in a stepwise fashion. In this way, the second separation net 130 and the membrane sheet 100 are stacked in a step form, so that the overall membrane uniformity is ensured when the roll-type membrane element is rolled up, and the water filtration efficiency is improved.
In one embodiment, referring to fig. 1, the flow of the water channels in first spacer mesh 120 is greater than the flow of the water channels in second spacer mesh 130, i.e., the flow channels in first spacer mesh 120 are greater than the flow channels in second spacer mesh 130. Further, the first screen 120 is a screen for raw water circulation, and the second screen 130 is a screen for produced water circulation.
Because the raw water solution contains more particles, the thickness and the size of the flow channel arrangement of the first separation net 120 for guiding the raw water solution are larger than those of the second separation net 130 for guiding the filtered produced water solution, so that the solution is not blocked, and the filtering efficiency is accelerated.
In one embodiment, the folded filter membrane 110 has the same dimensions as the first and second spacers 120 and 130, so that the stacked membrane sheets 100 and the second spacers 130 have better dimensional symmetry and post-membrane uniformity is ensured during rolling.
In a specific embodiment, the roll-type membrane element comprises at least eighteen membrane sheets 100, which increases the accuracy of the filtration.
In a specific embodiment, each of the first and second separation nets 120 and 130 includes a plurality of first and second support bars vertically disposed, the first support bars are laid on the second support bars, and the thickness of the second support bars is greater than that of the first support bars, so that two adjacent second support bars form a flow channel. The first supporting strip is used as a connecting line for fixing the second supporting strip. Therefore, the solution flows in the flow channel formed by the second supporting strips in the first separation net 120 and the second separation net 130, the flow rate of the filtered water is increased, and the filtering efficiency is improved.
In a second aspect, the present invention provides a rolled membrane cartridge, which includes the rolled membrane element and the central column (the cartridge is rolled in the manner of the prior art, not shown in the figure) in the above-mentioned embodiment.
The central column is a hollow cylinder, a plurality of through holes are arranged on the central column, the roll-type membrane element is wound on the central column, and the outlet of the second separation net 130 is matched with the through holes. The end of the roll-type membrane element is provided with a water inlet which is communicated with the first separation net 120.
Therefore, the raw water solution enters the first separation net 120 in the membrane through the water inlet, then penetrates through the filter membrane 110, enters the second separation net 130, flows into the through hole of the central column along the opening of the second separation net 130 and is discharged, the accuracy of water filtration is improved through the arrangement of the roll-type membrane element, and the efficiency of water filtration is improved.
In a third aspect, the embodiment of the present invention provides a roll-type membrane column, which includes a membrane shell and a roll-type membrane filter element disposed in the membrane shell. The membrane shell effectively protects the roll-type membrane filter element, and the roll-type membrane filter element is utilized to improve the water filtering accuracy and the water filtering efficiency.
