Embodiment 1

[0028] refer to Figure 1-6 As shown, a petal-shaped internal support framework for tubular filter membranes includes: a central column 1 and a support arm 2 surrounding the outside of the central column 1, and there are a plurality of support arms 2 along the axis of the central column 1 Extending in the direction, a medium channel 3 is formed between two adjacent support arms 2 . The number of support arms 2 is generally more than 3, and the number of support arms 2 in this embodiment is 6. The more the number of arms 2 is, the better the effect of making the tubular filter membrane 10 arranged outside it is, which can effectively prevent the filter membrane 10 from being damaged, but too many arms 2 will also cause the media channel 3 The reduction of the area results in a decrease in the filtering / separation effect, therefore, an appropriate number of arms 2 should be selected.

[0029] The cross-sectional shape of the central column 1 in the present invention is any sha...

Embodiment 2

[0034] refer to Figure 7 As shown, the difference from Embodiment 1 is that the end of each arm 2 is provided with more than two first bifurcated arms 4, and the end of the first bifurcated arm 4 has a bifurcated end portion 5. The cross section of the fork end 5 is any shape such as arc, semicircle, triangle, polygon, or irregular curve.

[0035] In order to better support the filter membrane 10, the bifurcated end 5 is provided with an arc-shaped support surface (not shown in the figure). Because it has a larger contact surface, the support effect is good, and the filter membrane 10 is effectively prevented from being damaged.

[0036] The petal-shaped inner support framework for the tubular filter membrane 10 of the present invention is a petal-shaped structural profile formed by one-time processing. Its structure is simple, and various metal materials (including but not limited to: stainless steel, titanium, Aluminum, etc.) or non-metallic materials (including but not li...

Abstract

The invention relates to a petal-shaped inner supporting framework applied to a tubular filtering membrane and application thereof. The supporting framework comprises a middle column and a plurality of supporting arms which are arranged around the outer side of the middle column, wherein the supporting arms extend in the axial direction of the middle column, and medium channels are formed every two adjacent supporting arms. The petal-shaped inner supporting framework has the beneficial effects that the structure can be once formed through equipment, and many times of processing is avoided; when the petal-shaped inner supporting framework is arranged in the tubular filtering membrane, the cross sections of the medium channels are expanded and optimized; thus, a filtering efficiency of the filtering membrane is improved, higher filtering membrane filtering flux is obtained, and a better filtering / separating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of membrane filtration / membrane separation, in particular to a petal-shaped inner support framework for tubular filter membranes and its application. Background technique [0002] With the development of industrialization, a large amount of domestic and industrial waste water is discharged into water bodies, which makes the water sources that human beings rely on increasingly polluted. On the other hand, the fresh water sources available on the earth are becoming more and more scarce. There are more and more cities, and governments of all countries hope to improve the utilization rate of existing water resources through advanced treatment and reuse of industrial and domestic wastewater. Membrane separation technology has been gradually popularized and applied because of its advantages of high separation efficiency, simple equipment, convenient operation, no phase change and energy saving. The common filter ...
