Description

Technical Field

[0001] This utility model relates to the field of desalination membrane technology, specifically to a high-efficiency seawater desalination membrane module. Background Technology

[0002] Seawater desalination membrane modules are the core components of seawater desalination systems. They typically employ membrane separation technologies such as reverse osmosis or nanofiltration. These modules consist of multiple layers of semi-permeable membranes made of special materials. These membranes have selective permeability and can effectively remove salt, minerals, microorganisms, and other impurities from seawater to produce freshwater. Seawater is pushed through the membrane module by a high-pressure pump, the freshwater permeates through the membrane and is collected, while the concentrated brine is discharged. This highly efficient seawater desalination technology is widely used in coastal and water-scarce areas, providing important support for solving the problem of water shortage.

[0003] During seawater desalination, impurities such as suspended solids, colloids, and organic matter are trapped on the membrane surface and form a fouling layer. These pollutants can clog the membrane pores and prevent water molecules from passing through, thus causing a decrease in membrane flux. The membrane fouling problem is even more serious when pretreatment is insufficient.

[0004] In existing seawater desalination technologies, chemical cleaning is a common method to address membrane fouling. This method mainly uses acidic solutions to remove pollutants while using alkaline solutions to remove organic dirt and biofilm, thereby cleaning the membrane surface. Although chemical cleaning performs well in removing pollutants, its frequent use may damage the membrane material, leading to a shortened membrane lifespan. Therefore, to address the above issues, a high-efficiency seawater desalination membrane module is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figures 1-6 This utility model provides a technical solution:

[0029] A high-efficiency seawater desalination membrane module includes a desalination module 2. A bucket-shaped tube 1 is fixedly connected to the front end of the desalination module 2. A cleaning component 3 is installed inside the bucket-shaped tube 1. A solenoid valve 4 is fixedly connected to the rear end of the desalination module 2. A water collection pipe 5 is fixedly connected to the lower end of the desalination module 2. The cleaning component 3 includes an extension tube 31. A seawater through hole 32 and a seawater channel 33 are opened inside the extension tube 31. An internal frame 34 is fixedly connected to the internal frame 31. An extension rod 36 is rotatably connected to the internal frame 34 through a bearing 35. A turbine blade 37 is fixedly connected to the front end of the extension rod 36. A spiral blade 38 is fixedly connected to the outer side of the extension rod 36. The spiral blade 38 is clearance-fitted with the inner side of the seawater channel 33. The outer side of the extension tube 31 is fixedly connected to the inner side of the desalination module 2.

[0030] As a further implementation of this solution, the desalination module assembly 2 includes a conical shell 21, an inner cylinder 22 fixedly connected to the inner side of the conical shell 21, a freshwater outlet 23 opened on the inner side of the inner cylinder 22, a connecting pipe 24 fixedly connected to the outer side of the conical shell 21, a conical groove 25 formed by the inner side of the conical shell 21 and the outer side of the inner cylinder 22, and a desalination membrane body 26 embedded in the conical groove 25. The front end and rear end of the desalination membrane body 26 are tightly attached to the inner side of the conical shell 21. Through the above arrangement, efficient filtration and desalination can be achieved. At the same time, the tight fit between the desalination membrane body 26 and the inner side of the conical shell 21 can effectively prevent seawater leakage and ensure the stability of the filtration effect.

[0031] As a further implementation of this scheme, the diameter of the cone shell 21 gradually expands from front to back, and the connecting pipe 24 is set at the rear end of the cone shell 21. Through the above arrangement, it is convenient to collect the filtered seawater into the connecting pipe 24, thereby improving the overall operating efficiency of the device.

[0032] As a further implementation of this scheme, the conical groove 25 is connected to the inside of the inner cylinder 22 through the freshwater outlet 23. The inner side of the connecting pipe 24 is a hollow structure. The conical groove 25 is connected to the inside of the connecting pipe 24. The lower end connecting pipe 24 is fixed to the water collection pipe 5. The inside of the lower end connecting pipe 24 is connected to the inside of the water collection pipe 5. Through the above settings, the desalinated seawater can be stably collected and discharged, improving the operational stability and reliability of the device.

[0033] As a further implementation of this scheme, the cone shell 21 has fixing holes at both the front and rear ends. The two fixing holes of the cone shell 21 are fixedly connected to the extension tube 31. The front and rear ends of the extension tube 31 extend out of the cone shell 21. The front end of the extension tube 31 is fixedly connected to the funnel-shaped tube 1, and the rear end of the extension tube 31 is fixedly connected to the solenoid valve 4. The inside of the funnel-shaped tube 1 is connected to the seawater channel 33. Through the above settings, a channel is provided for the preliminary filtration of seawater, which improves the filtration efficiency and overall performance of the device, and at the same time facilitates the removal of impurities.

[0034] As a further implementation of this scheme, the seawater channel 33 is connected to the interior of the inner cylinder 22 through the seawater through hole 32, and the seawater through hole 32 is attached to the desalination membrane body 26. Through the above settings, the quality of the desalinated seawater is ensured, and the desalination efficiency and water quality assurance capability of the device are improved.

[0035] Workflow: During seawater desalination, the funnel-shaped pipe 1 is connected to the existing water pipe by bolts, and the funnel-shaped pipe 1 and the water pipe are sealed by a sealing ring. The seawater flowing out of the water pipe enters the extension pipe 31 through the funnel-shaped pipe 1. Since the diameter of the funnel-shaped pipe 1 gradually narrows from front to back, the seawater enters the extension pipe 31 at a faster speed. After the seawater enters the seawater channel 33, large particles of impurities are filtered and retained in the seawater channel 33 through the seawater through-hole 32. The filtered seawater comes into contact with the desalination membrane body 26 after passing through the seawater through-hole 32. The seawater is desalinated by the filtration of the seawater by the desalination membrane body 26. The desalinated seawater flows out through the freshwater outlet 23 and enters the conical groove 25. Due to the shape design of the conical shell 21, the seawater will concentrate at the rear end of the conical shell 21 and flow into other conical shells 21 through the connecting pipe 24 until it reaches the connecting pipe 24 at the bottom of the flow channel. It then flows into the water collection pipe 5 for centralized collection.

[0036] When cleaning pollutants, most of the pollutants remain inside the seawater channel 33 and seawater through-hole 32. Following the same principle, under the rapid impact of seawater, the turbine blade 37 rotates, driving the extension rod 36 and the spiral blade 38 to rotate simultaneously. The extension rod 36 is rotatably connected to the internal frame 34 via a bearing 35. The bearing 35 has sealing properties, preventing impurities from affecting its rotation. When the spiral blade 38 rotates, it scrapes away impurities from the inner wall of the extension tube 31 and continuously transports the impurities to the rear end of the extension tube 31, reducing the impact of impurities on the filtration of the seawater through-hole 32. When the desalination efficiency of the device is low, the solenoid valve 4 is opened, using the impact of seawater to remove impurities from inside the extension tube 31. After cleaning, the solenoid valve 4 is closed. If further cleaning is desired, acidic and alkaline solutions are sequentially supplied into the funnel-shaped tube 1 to remove pollutants from inside the seawater through-hole 32.

[0037] Based on the above principles, the device does not require frequent filling of the desalination components with acidic and alkaline solutions for internal cleaning. Instead, it uses the pressure of the seawater as a driving force to rotate the cleaning components, thereby scraping out and moving contaminants inside the device and removing impurities. This improves the efficiency of seawater desalination and reduces the harm caused by commonly used solution cleaning methods.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
