Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a woven degassing membrane component. Background Technology

[0002] The degassed membrane uses a hollow fiber membrane structure, with water flowing along the outer side of the membrane fibers while a vacuum is maintained inside. The membrane fibers are arranged in parallel, and a fabric is woven with fine ropes perpendicular to the fiber direction. Figure 1 As shown in the diagram, in this structure, water flowing along the membrane fibers easily forms laminar flow, making it difficult for pollutants adhering to the membrane surface to be washed away. This gradually contaminates the membrane fiber surface, affecting the degassing membrane treatment effect. Simultaneously, the membrane fibers are thin and have limited pressure resistance, unable to withstand high water flow impact pressure, posing a risk of fiber breakage. Furthermore, when the membrane fibers break, the membrane structure loses its degassing function.

[0003] In view of this, this application provides a woven degassing membrane module to solve the problem that the current degassing membrane module adopts a woven fabric process, in which water flows along the membrane fibers and easily forms laminar flow, thus affecting the treatment effect. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art and to provide a woven degassing membrane component.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a woven degassing membrane assembly includes a shell, an inlet at the end of the shell and an outlet connected to the inlet, a plurality of membrane structures between the inlet and the outlet, a water distribution pipe and a water collection pipe and a partition between the plurality of membrane structures, and the membrane structure is formed by a plurality of membrane filaments woven together.

[0006] Furthermore, the membrane structure is braided.

[0007] Furthermore, a vacuum port for evacuating the membrane mechanism is provided on the side of the housing near the water inlet.

[0008] Furthermore, the housing is provided with a nitrogen port near the outlet for purging the membrane mechanism with nitrogen.

[0009] Furthermore, the water distribution pipe and the water collection pipe are located in the middle of the shell and are arranged horizontally.

[0010] Furthermore, the partition is located in the middle of the housing and is arranged vertically.

[0011] Furthermore, the membrane structures are arranged horizontally and in parallel with each other.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This application provides a plurality of membrane structures between the inlet and outlet at the end of the shell. The plurality of membrane structures are provided with a water distribution pipe, a water collection pipe, and a partition between the water distribution pipe and the water collection pipe. The membrane structure is made of a plurality of membrane filaments woven together, so that the membrane filaments are interwoven and cross-shaped. Turbulence is generated during the water flow, which reduces concentration polarization, reduces membrane fouling, extends the service life of the membrane, and improves the treatment effect.

[0014] 2. The membrane structure of this application is braided into a twisted shape, which increases the strength of the membrane fibers, enabling it to withstand higher water pressure, allowing for greater flow rates, and improving the membrane's processing capacity. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] Reference Figures 2-3 As shown in the preferred embodiment of this utility model, a woven degassing membrane assembly includes a housing 1. The housing 1 has an inlet 2 and an outlet 3 connected to the inlet 2 at one end. A plurality of membrane structures 4 are arranged between the inlet 2 and the outlet 3. A water distribution pipe 5, a water collection pipe 6, and a partition 7 are arranged between the plurality of membrane structures 4. The membrane structure 4 is woven from a plurality of membrane filaments, so that the membrane filaments are interwoven, and turbulence is generated during water flow, which reduces concentration polarization, reduces membrane fouling, extends the service life of the membrane, and improves the treatment effect.

[0021] As a preferred embodiment of this utility model, it may also have the following additional technical features: the membrane structure 4 is braided, specifically, three thin membrane filaments are placed side by side, then the left one is crossed with the middle one, and then the right one is crossed with the middle one, and so on, to weave a thick membrane filament. The crisscrossing of the membrane filaments generates turbulence during water flow, reducing concentration polarization, reducing membrane fouling, and extending the membrane's service life. The overall strength of the braided membrane filaments is increased, enabling it to withstand higher water pressure, allowing for higher flow velocities, and improving the membrane structure's throughput.

[0022] In this embodiment, the housing 1 has a vacuum port 8 for evacuating the membrane mechanism near the water inlet 2; and a nitrogen port 9 for purging the membrane mechanism with nitrogen gas near the water outlet 3. Thus, when the liquid comes into contact with the membrane fibers, the interior of the membrane fibers is evacuated or purged with nitrogen gas, allowing gas in the liquid to permeate through the membrane, reach the interior of the membrane fibers, and be discharged from the vacuum port, achieving liquid degassing.

[0023] In this embodiment, the water distribution pipe 5 and the water collection pipe 6 are located in the middle of the housing 1 and are arranged horizontally, while the partition 7 is located in the middle of the housing 1 and is arranged vertically. This allows the liquid to enter the membrane mechanism from the inlet, flow from the center outwards through the central water distribution pipe, pass over the outer edge of the partition, and then converge into the water collection pipe before flowing out from the outlet.

[0024] In this embodiment, several membrane units 4 are arranged horizontally and parallel to each other. This allows the liquid to fully contact the membrane units, effectively performing degassing.

[0025] The working principle of this utility model is as follows: The woven membrane fibers are encapsulated in the housing 1, with the two ends of the housing 1 being the inlet 2 and the outlet 3; the liquid enters the membrane mechanism 4 through the inlet 2, flows from the center to the surrounding area through the central water distribution pipe 5, flows over the outer edge of the partition 7, and then converges into the water collection pipe 6, flowing out from the outlet 3; when the liquid comes into contact with the membrane fibers, the inside of the membrane fibers is purged by vacuuming or vacuuming with nitrogen, allowing the gas in the liquid to pass through the membrane and reach the inside of the membrane fibers, and is discharged from the component through the vacuum port, thus achieving the purpose of liquid degassing.

[0026] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
