Embodiment 1

[0031] Example 1, in some implementations, the cross-sectional shape of the hollow cavity 4 is circular; and / or,

[0032] There are three hollow cavities 4 , and the three hollow cavities 4 are spaced apart from each other along the circumferential direction of the supporting base layer 3 , and the solid support portion 5 is located between the three hollow cavities 4 . The hollow cavity of the present invention is preferably circular, and water can pass through it. The hollow cavity of the present invention is preferably three. The three hollow cavities are distributed along the axial direction of the supporting base at intervals, and can form three channels for water supply and circulation.

[0033] Specific embodiments of the present invention are as attached figure 1 As shown, the present invention provides an integrally formed three-channel membrane filament structure of a hollow fiber membrane module, including a separation layer 1 (nanofiltration material), an intermedi...

Embodiment 2

[0035] Example 2, in some implementations, in the cross section of the support base layer 3, the solid support part 5 includes two partition bars arranged in the hollow cavity 4, through the partition bars, the The hollow cavity 4 is divided into 4 sub-cavities (preferably, the size of the 4 sub-cavities is the same). Such as figure 2 As shown, in Embodiment 2 of the present invention, the hollow cavity is separated by two partition bars, thereby forming 4 sub-cavities, thereby forming 4 channels for water supply and circulation.

[0036] In some embodiments, in the cross-section of the supporting base layer 3, two partition bars are vertically intersected; the four sub-cavities are fan-shaped structures with a central angle of 90°. This is the preferred structural form of the four sub-cavities of the present invention, and the preferred arrangement form of the partition bar.

[0037] Specific embodiment of the present invention 2 is attached figure 2 As shown, the presen...

Embodiment 3

[0038]Example 3, in some implementations, in the cross section of the supporting base layer 3, the solid support part 5 includes three partition bars arranged in the hollow cavity 4, through the partition bars, the The hollow cavity 4 is divided into three sub-cavities (the three sub-cavities are preferably of the same size). like image 3 As mentioned above, in Embodiment 3 of the present invention, the hollow cavity is divided by three partition bars, thereby forming three sub-cavities, thereby forming three channels for water supply and circulation.

[0039] In some embodiments, in the cross-section of the supporting base layer 3, one end of each of the three spacers is connected to the center of the separation layer 1, and the other ends of each extend outward in the radial direction, and are connected to each other. The two partition bars are rotated by 120° in the circumferential direction; and / or,

[0040] In the cross-section of the support base layer 3, the three pa...

Abstract

The invention provides a hollow fiber membrane yarn structure, a composite filter element assembly and a water purifying device.The hollow fiber membrane yarn structure comprises a separation layer, a middle supporting layer and a supporting base layer, the separation layer is of a hollow cylindrical structure, the middle supporting layer is arranged in an inner cavity of the separation layer in a penetrating mode, and the supporting base layer is arranged on the inner periphery of the middle supporting layer in a penetrating mode; a solid supporting part is arranged in the center of the inner circumference of the supporting base layer, the inner circumference of the supporting base layer is further provided with at least two hollow cavities extending in the axis direction of the separation layer, the solid supporting part is located between the at least two hollow cavities, the separation layer can filter impurities, and the middle supporting layer and the supporting base layer can both allow fluid to penetrate through. The separation layer is reinforced and supported through the middle supporting layer, the compression strength of the membrane filaments is improved, the problem of filament breakage can be effectively solved, and the integrated design can reduce the production cost and facilitate assembly.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a hollow fiber membrane structure, a composite filter element assembly and a water purification device. Background technique [0002] At present, the hollow fiber membrane module directly casts the membrane filaments in the module, and the membrane filaments have no internal support. If the water pressure in the module is too high, the membrane filaments will easily break and be damaged. Therefore, in order to improve the compressive strength of the membrane filaments and reduce the broken filament rate, it is necessary to develop a structure that can support the membrane filaments inside to increase the strength of the membrane filaments and prolong the service life of the membrane filaments. [0003] Due to technical problems such as the hollow fiber membrane filaments in the traditional filter element assembly in the prior art are easily broken and damag...
