Description

Technical Field

[0001] This utility model relates to the field of pipeline layout technology for electrostatic desalination equipment, and specifically to an electrostatic desalination pipeline module that prevents water flow deviation. Background Technology

[0002] Electrodialysis (EDI) desalination equipment scientifically integrates electrodialysis and ion exchange technologies. Through the selective permeation of cation and anion membranes and the exchange of ions in water by ion exchange resins, ions migrate directionally under an electric field, achieving deep purification and desalination. Furthermore, the hydrogen and hydroxide ions generated by water electrolysis continuously regenerate the resin. Therefore, the EDI water treatment process can continuously produce high-quality ultrapure water without the need for acid or alkali chemical regeneration. It boasts advanced technology, compact structure, and simple operation, and can be widely used in the power, electronics, pharmaceutical, chemical, food, and laboratory fields, representing a green revolution in water treatment technology.

[0003] Currently, this equipment on the market places the inlet side A and the outlet side B on the same side, which causes severe flow deviation in the electro-deionization module. Due to the flow deviation, when the system is shut down, the water inside the equipment is automatically emptied through the online instrument flow channel, causing water loss from the module and potentially leading to module burnout. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an electro-desalination pipeline module for preventing water flow deviation, comprising:

[0005] Large-scale electro-deionization module;

[0006] The electro-desalination module includes at least two sub-modules arranged in parallel, and also includes an inlet pipe for water inlet and an outlet pipe for water outlet. The inlet pipe is located below the sub-module, and the outlet pipe is located above the sub-module. The inlet pipe is connected to the bottom of each sub-module through a first branch pipe, and the outlet pipe is connected to the top of each sub-module through a second branch pipe. The inlet pipe and outlet pipe are arranged horizontally, the first branch pipe is arranged perpendicular to the inlet pipe, and the second branch pipe is arranged perpendicular to the outlet pipe. The inlet side of the inlet pipe and the outlet side of the outlet pipe are distributed on both sides of the electro-desalination module and are symmetrically arranged about the center of the electro-desalination module.

[0007] A further embodiment of this utility model is that each of the electro-desalination modules is provided with six sub-modules connected in parallel.

[0008] A further embodiment of this utility model is that the electro-desalination module has multiple layers, and the multiple electro-desalination modules are connected in parallel and arranged vertically.

[0009] A further embodiment of this utility model is that the inlet pipes of each layer of the electro-desalination module are connected by a first branch pipe, and the outlet pipes of each layer of the electro-desalination module are connected by a second branch pipe, with the second branch pipe connecting upwards from the bottommost branch pipe.

[0010] A further embodiment of this utility model is that the first diversion pipe and the second diversion pipe are both arranged perpendicular to the inlet pipe.

[0011] A further embodiment of this utility model is that the connection point at the bottom of the inlet pipe and the first branch pipe is the inlet confluence point, and the top bend of the second branch pipe is the outlet confluence point.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention addresses the combination of multiple electrostatic desalination submodules by employing a "parallel arrangement" similar to building water supply and drainage systems. The inlet and outlet ends are distributed on opposite sides. Within the same floor's large electrostatic desalination module, water entering through the inlet pipe flows into the submodule via the first branch pipe, and then exits through the outlet pipe via the second branch pipe, flowing out from the direction furthest from the inlet end. This ensures that the water volume flowing out of different submodules remains the same throughout the flow path, minimizing local damage to each submodule and reducing the risk of submodule burnout. Furthermore, it prevents internal moisture from being automatically drained by online instruments during system shutdown, significantly protecting equipment safety.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Example 1

[0023] like Figure 1 This embodiment provides an electro-desalination pipeline module to prevent water flow deviation, including: electro-desalination large module 1.

[0024] In this embodiment, the electro-desalination module 1 includes at least two sub-modules 10 connected in parallel. In this embodiment, each electro-desalination module 1 has six sub-modules 10 connected in parallel. Of course, the number is not specifically limited. As a large-scale electro-desalination device, there are usually multiple sub-modules 10, which is relatively large. The existing method of setting the inlet and outlet water on the same side can easily lead to flow deviation, thereby increasing the risk of equipment burnout.

[0025] In this embodiment, the electro-deionization module 1 further includes an inlet pipe 11 for water intake and an outlet pipe 12 for water discharge. The inlet pipe 11 is located below the sub-module 10, and the outlet pipe 12 is located above the sub-module 10. The inlet pipe 11 is connected to the lower part of each sub-module 10 via a first branch pipe 13, and the outlet pipe 12 is connected to the upper part of each sub-module 10 via a second branch pipe 14. The inlet pipe 11 and the outlet pipe 12 are arranged horizontally, the first branch pipe 13 is arranged perpendicularly to the inlet pipe 11, and the second branch pipe 14 is arranged perpendicularly to the outlet pipe 12. The water inlet side of the inlet pipe 11 and the water outlet side of the outlet pipe 12 are distributed on both sides of the electro-deionization module 1, symmetrically arranged about the center of the electro-deionization module 1. In this way, a "parallel arrangement" similar to building water supply and drainage is adopted. The design places the inlet and outlet ends on opposite sides. In the large electro-deionization module 1 on the same floor, the water entering through the inlet pipe 11 flows through the first branch pipe 13 into the sub-module 10, and then through the second branch pipe 14 into the outlet pipe 12, flowing out from the direction away from the inlet end. This ensures that the water volume flowing out of different sub-modules 10 remains the same throughout the flow path, resulting in similar local damage to each sub-module 10 and minimizing flow deviation. This reduces the risk of sub-module 10 burnout and prevents the internal moisture from being automatically drained by online instruments when the system is shut down, greatly protecting the equipment safety. When two sub-modules 10 are used simultaneously, they can prevent deviation. When six sub-modules 10 are used, the deviation prevention effect is significant, providing substantial protection.

[0026] Example 2

[0027] like Figure 2 In this embodiment, the electro-desalination module 1 has multiple layers, and the multiple layers of the electro-desalination module 1 are connected in parallel and arranged vertically.

[0028] In this embodiment, the inlet pipes 11 of each layer of the electro-desalination module 1 are connected by a first branch pipe 15, and the outlet pipes 12 of each layer of the electro-desalination module 1 are connected by a second branch pipe 16. The second branch pipe 16 connects upwards from the bottommost branch pipe. Furthermore, both the first branch pipe 15 and the second branch pipe 16 are perpendicular to the inlet pipe 11. The connection point at the top of the inlet pipe 11 and the first branch pipe 15 is the inlet confluence point 17, and the bottom end of the second branch pipe 16 is bent to form the outlet confluence point. The confluence point 18 ensures that the inlet and outlet water of the multi-layer electro-deionization module 1 are located on different sides, with the water flow from the bottom layer to the top layer. This allows water to flow through each sub-module 10 of the multi-layer electro-deionization module 1, ensuring that the water pipeline path is the same. The elevation at the outflow confluence point 18 is higher than the highest point of the equipment outlet. Even when the system is shut down, the flow channels of the normally open online instruments equipped with the system will not cause water loss from the sub-module 10, ensuring that all parts of the sub-module 10 are fully moistened and reducing the risk of burn-out.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
