Description

Technical Field

[0001] This utility model relates to the field of membrane separation technology, and in particular to a multi-channel feeding device for water-oil phase solutions. Background Technology

[0002] Composite separation membranes are thin film structures composed of multiple layers of different materials, achieving selective separation through the synergistic effect of different components. Composite separation membranes are typically composed of a support layer (providing mechanical strength) and a functional layer (achieving selective separation), and some structures also include an interface layer to enhance bonding.

[0003] In the fabrication of composite separation membranes, the water-oil phase solution is typically delivered to the membrane surface through a single feed pipe, resulting in uneven distribution of the solution in the transverse direction of the membrane. This uneven contact can lead to the following problems:

[0004] 1. Local concentration polarization: The monomer concentration varies significantly in different regions of the membrane in the transverse direction, resulting in differences in the thickness or degree of crosslinking of the polyamide separation layer, which ultimately leads to uneven transverse performance of the membrane.

[0005] 2. Performance fluctuations: Unstable separation efficiency and product recovery rate affect industrial applications.

[0006] In the prior art, although the separation performance can be improved by optimizing the film-forming formula (such as increasing the monomer concentration) or adjusting the operating parameters (such as the machine speed), the structural defect of uneven feed distribution has not been fundamentally solved. Therefore, how to fundamentally improve the transverse stability of the membrane is the technical problem that needs to be solved in this case. Utility Model Content

[0007] To address the above problems, this invention provides a multi-channel feeding device for water-oil phase solutions that features a compact structure, improves solution distribution uniformity, and enhances membrane lateral stability.

[0008] The technical solution of this utility model is:

[0009] A multi-channel feeder for water-oil phase solutions includes:

[0010] The feed tank has a diaphragm discharge port at the top and several evenly distributed inlet holes at the bottom; and

[0011] A plurality of multi-angle nozzles are provided, evenly distributed and detachably fixedly mounted on the liquid inlet hole; the multi-angle nozzles include:

[0012] The liquid inlet is detachably and sealed at the bottom of the liquid tank, and has a flow channel inside.

[0013] The liquid outlet is located inside the liquid tank and its bottom is detachably and sealed to the liquid inlet. The top of the liquid outlet has an arc-shaped structure and is provided with several evenly distributed liquid inlet holes. The liquid inlet holes are connected to the flow channel. The cross-section of the liquid inlet holes increases sequentially from the inside to the outside.

[0014] Specifically, the liquid outlet section has a circular cross-section.

[0015] Specifically, the cross-section of the liquid outlet section has an elliptical structure.

[0016] Specifically, the cross-section of the liquid outlet section has a fan-shaped structure.

[0017] Specifically, the multi-angle nozzle is located below the solution surface.

[0018] Specifically, a flow regulating valve with a detachable, sealed, and fixed connection is provided below the liquid inlet section.

[0019] Specifically, each of the multiple liquid inlet sections is detachably and sealed to the top of the buffer tank;

[0020] The buffer tank is equipped with a liquid inlet at the bottom.

[0021] Specifically, the bottom of the buffer box has an arc-shaped structure.

[0022] Specifically, the liquid tank has a liquid outlet located on its lower side;

[0023] The outlet is connected to a circulating pump via a pipe;

[0024] The circulating pump returns the liquid to the buffer tank through a filter.

[0025] Specifically, a total flow regulating valve is provided between the filter and the buffer tank.

[0026] This invention includes a feed tank and a multi-angle nozzle. The multi-angle nozzle includes a detachably sealed inlet section at the bottom of the feed tank and an outlet section detachably sealed and fixed within the feed tank. The top of the outlet section has an arc-shaped structure and is provided with several evenly distributed inlet holes. The evenly distributed inlet holes at the bottom of the feed tank, combined with the multi-angle nozzle, form a multi-channel diversion structure, which can achieve regional synchronous injection of oil-water phase solution within a unit time, effectively avoiding local high concentrations or phase separation lag. The arc-shaped top surface of the outlet section and the gradually expanding cross-section of the inlet holes allow the fluid to form laminar diffusion at the outlet, improving the radial uniformity of the solution distribution within the reaction vessel.

[0037] like Figure 1 As shown, the multi-channel feeder for the water-oil phase solution includes:

[0038] The feed tank 100 has a diaphragm discharge port at the top and several evenly distributed inlet holes at the bottom; and

[0039] A number of multi-angle nozzles 200 are provided and are detachably and fixedly mounted on the liquid inlet hole;

[0040] The multi-angle nozzle 200 includes:

[0041] The liquid inlet 210 is detachably and sealed to the bottom of the liquid tank 100, and has a flow channel inside;

[0042] The liquid outlet 220 is disposed in the liquid tank 100, and its bottom is detachably and sealed to the liquid inlet 210 by threads; the top of the liquid outlet 220 has an arc-shaped structure and is provided with a number of evenly distributed liquid inlet holes; the liquid inlet holes are connected to the flow channel; the cross-section of the liquid inlet holes increases sequentially from the inside to the outside.

[0043] The uniformly distributed inlet holes at the bottom of the feed tank 100, combined with multi-angle (arc-shaped) nozzles, form a multi-channel diversion structure, enabling synchronous injection of oil-water phase solutions into different areas within a unit of time, effectively avoiding localized excessive concentrations or delayed phase separation. The arc-shaped top surface and gradually expanding cross-section of the inlet holes at the outlet allow for laminar diffusion of the fluid at the outlet, improving the radial uniformity of the solution distribution within the reaction vessel.

[0044] like Figure 2 As shown, the liquid outlet section 220 has a circular cross-section.

[0045] like Figure 3 As shown, the liquid outlet section 220 has an elliptical cross-section.

[0046] like Figure 4 As shown, the liquid outlet section 220 has a fan-shaped cross-section.

[0047] Figure 2 It has a circular structure. Figure 3 It has an elliptical structure. Figure 4 The structure is fan-shaped, and to facilitate detachable installation with the liquid inlet 210, its bottom is designed with adaptability, such as... Figure 2 The circular bottom portion was cut off, and a connection portion for threaded connection with the liquid inlet 210 was added. Figure 3 The elliptical structure was also partially removed to add a connecting part.

[0048] like Figure 1 As shown, the multi-angle nozzle 200 is located below the solution surface, the horizontal line in the feed tank 100 is the liquid surface, and a pair of circles on the liquid surface are feed rollers. The film material is pressed down to the bottom of the liquid surface through the pair of feed rollers, and fully contacts and reacts with the liquid.

[0049] A flow regulating valve with a detachable and sealed fixed connection is provided below the liquid inlet section 210 to improve flow controllability.

[0050] The plurality of liquid inlet sections 210 are detachably and sealedly fixedly connected to the top of the buffer tank 300;

[0051] The bottom of the buffer tank 300 is equipped with a liquid inlet.

[0052] The buffer tank 300 serves as an intermediate container to temporarily store the solution input from the inlet section 210. Its volumetric buffering mechanism compensates for pressure fluctuations caused by differences in flow rates across multiple channels, ensuring stable downstream feed pressure. The bottom inlet's design facilitates gravity-assisted drainage, reducing pumping energy consumption.

[0053] The bottom of the buffer box 300 has an arc-shaped structure.

[0054] The curved bottom transforms the vertical impact force generated by the falling material into a tangential component force through the curved surface structure, reducing local stress concentration and preventing deformation or cracking of the bottom of the buffer box 300 due to long-term impact.

[0055] A liquid outlet is provided on the lower side of the liquid tank 100;

[0056] The outlet is connected to the circulating pump via a pipe;

[0057] The circulating pump returns the liquid to the buffer tank 300 through a filter.

[0058] A total flow regulating valve is installed between the filter and the buffer tank 300.

[0059] like Figure 6 As shown, a detachable and fixed anti-surge plate 400 is provided below the liquid surface in the liquid tank 100. The anti-surge plate 400 is provided with a number of evenly distributed downward-extending arc-shaped recesses 410, and the arc-shaped recesses 410 are provided with a number of liquid passage holes.

[0060] The curved concave portion 410 of the arc-shaped surface guides the flow, reducing the energy of lateral fluctuations in the liquid surface. Combined with the liquid passage holes, it achieves the release of the flow velocity gradient, effectively reducing the amplitude of the liquid surface, reducing turbulent disturbances, and improving the uniformity of the membrane reaction and the stability of separation.
