Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a novel pollutant membrane catalytic decomposition water treatment device. Background Technology

[0002] In the wave of rapid global industrialization, emerging industries are constantly springing up, resulting in a continuous influx of new pollutants with complex structures and unique properties into natural water bodies. These new pollutants encompass emerging organic pollutants, nanomaterials, and microplastics, whose chemical structures differ significantly from traditional pollutants, often proving ineffective with conventional biological and physical treatment methods. For example, the traditional activated sludge process relies on microorganisms to decompose and metabolize pollutants; however, the resistance to degradation of new pollutants makes it difficult for microorganisms to effectively transform them, resulting in far from satisfactory treatment outcomes. Traditional filtration technologies, limited by filter pore size and materials, are almost entirely unable to effectively retain new pollutants such as microplastics and nanoparticles with extremely small particle sizes and unique surface properties.

[0003] Furthermore, common chemical treatment methods require the use of large quantities of chemicals to remove new pollutants, leading to a sharp increase in treatment costs and the potential for secondary pollution from the introduced chemicals, further deteriorating the aquatic ecosystem. Even more problematic is the extreme inconvenience of replacing and maintaining the catalytic membrane, a core component of traditional water treatment systems. Once the catalytic membrane deteriorates or is damaged, significant manpower and resources are often required for disassembly and replacement. In some systems, due to design flaws, catalytic membrane replacement is simply not feasible, severely impacting the continuous and stable operation of the system. Therefore, developing a new, efficient, low-cost, environmentally friendly, and easy-to-maintain pollutant water treatment technology is urgently needed. Utility Model Content

[0010] In a preferred embodiment of this utility model, the lifting assembly includes a bracket, a threaded rod, and a guide rod. Lifting cavities are symmetrically arranged on both sides of the reaction tank. The threaded rod is rotatably installed between the two sides of the inner wall of the lifting cavity, and the guide rod is fixedly installed between them.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a novel pollutant membrane catalytic decomposition water treatment device, comprising a reaction tank 110, with an inlet pipe 111 and an outlet pipe 112 installed on both sides of the reaction tank 110, and valves installed on both the inlet pipe 111 and the outlet pipe 112. An aeration component and a mixing component are installed at the bottom of the reaction tank 110, and two parallel support frames 130 are slidably installed on the inner wall of the reaction tank 110. A catalytic membrane 131 is inserted into the inner wall of the support frame 130. Support rods 132 are fixedly installed at the four corners of the top of the support frame 130 that is relatively close to the bottom of the reaction tank 110. The top of the support rods 132 is fixedly inserted through the upper support frame 130 and a support plate 133 is fixedly installed. A lifting component is installed on the support plate 133. A partition plate 113 is fixedly installed at the bottom of the inner wall of the reaction tank 110, and a sealing groove matching the partition plate 113 is provided at the bottom of the support frame 130.

[0022] In some specific implementations, the aeration assembly includes an aeration pipe 140, which is fixedly connected to the inner wall of the reaction tank 110. The aeration pipe 140 is serpentine in shape, with one end penetrating the reaction tank 110 and equipped with an air inlet. Multiple air outlets are provided on the aeration pipe 140, with a waterproof and breathable membrane installed on the inner wall of each outlet. A gap is provided between the aeration pipe 140 and the bottom of the inner wall of the reaction tank 110. The serpentine shape of the aeration pipe 140, fixedly connected to the inner wall of the reaction tank 110, increases the contact area between the aeration pipe 140 and the water, allowing air to be more evenly distributed within the reaction tank 110. This increases the dissolved oxygen content in the water, providing more sufficient oxidant for the membrane catalytic reaction and helping to improve the decomposition efficiency of new pollutants. The aeration pipe 140's penetration through the reaction tank 110 and its air inlet facilitate connection to an external air source, simplifying operation and maintenance. The multiple air outlets allow gas to be rapidly dispersed into the water in the form of tiny bubbles, increasing the gas-liquid contact area, enhancing the mass transfer process, and further promoting the decomposition of new pollutants. The waterproof and breathable membrane installed on the inner wall of the air outlets effectively prevents water backflow into the aeration pipes 140, avoiding blockages that could affect aeration performance, ensuring stable operation of the aeration components, and reducing the probability of equipment failure.

[0023] In some specific implementations, the mixing assembly includes a first rotating shaft 150, stirring rods 151, and a second rotating shaft 152. The first rotating shaft 150 is symmetrically and rotatably mounted between the two sides of the inner wall of the reaction tank 110. Multiple stirring rods 151 are fixedly mounted on the first rotating shaft 150. One end of the first rotating shaft 150 passes through the reaction tank 110 and is fixedly mounted with a first bevel gear. A first side plate 153 is symmetrically and fixedly mounted on one side of the reaction tank 110. A second rotating shaft 152 is rotatably mounted between the two first side plates 153. A second bevel gear is symmetrically and fixedly mounted on the second rotating shaft 152. The first bevel gear and the second bevel gear are meshed together. A first motor 154 is mounted on one end of the second rotating shaft 152. The first rotating shaft 150 is positioned above the aeration pipe 140. The stirring rods 151 stir the water in the reaction tank 110, effectively breaking the laminar flow state of the water and ensuring full contact between the water to be treated, dissolved oxygen, and the catalytic membrane 131, significantly improving the reaction efficiency. For example, when treating water containing a variety of new pollutants, stirring can ensure that all kinds of pollutants have the opportunity to come into contact with the catalyst on the surface of the catalytic membrane 131, promoting the decomposition reaction.

[0024] In some specific implementations, the aeration pipe 140 is fixedly inserted through the partition 113, and the first rotating shaft 150 slides through the partition 113. The partition 113 has circular holes matching the aeration pipe 140 and the first rotating shaft 150, and sealing rings are fixedly installed on both sides of the circular holes. The supporting frame 130 has a sliding groove matching the catalytic membrane 131 on its inner wall, and supporting strips are symmetrically fixedly installed on the inner wall of the supporting frame 130. A guide plate 134 is fixedly installed between the two supporting frames 130, and the catalytic membrane 131 is slidably installed between the two supporting strips. The guide plate 134 and the partition 113 are on the same plane. The cooperation between the partition and the guide plate 134 can make the water flow in a U-shape, increasing the flow distance and improving the treatment effect.

[0025] Please see Figure 5 and Figure 7 The lifting assembly includes a bracket 160, a threaded rod 161, and a guide rod 162. Lifting chambers are symmetrically arranged on both sides of the reaction tank 110. The threaded rod 161 is rotatably installed on the inner wall of the lifting chamber and the guide rod 162 is fixedly installed on the inner wall of the lifting chamber. The bracket 160 is threaded on the threaded rod 161 and slidably installed on the guide rod 162. The bracket 160 is L-shaped. The top of the bracket 160 passes through the reaction tank 110 and is fixedly connected to the adjacent support plate 133. A drive assembly is installed on the top of the threaded rod 161. The threaded rod 161 and the guide rod 162 are symmetrically arranged, and the threaded rods 161 on both sides are also symmetrically arranged.

[0026] In some specific implementations, the drive assembly includes a U-shaped frame 170, a third rotating shaft 171, and a fourth rotating shaft 172. A fifth rotating shaft is fixedly mounted on the top of the threaded rod 161. The top of the fifth rotating shaft passes through the top of the lifting chamber and is fixedly mounted on a third bevel gear. The U-shaped frame 170 is fixedly mounted on the top of the reaction tank 110. The third rotating shaft 171 is symmetrically rotated and mounted on one side of the U-shaped frame 170. A fourth bevel gear is fixedly mounted on one end of the third rotating shaft 171, and the third and fourth bevel gears are meshed together. The other end of the third rotating shaft 171 passes through the U-shaped frame 170 and is fixedly mounted on a fifth bevel gear. The fourth rotating shaft 172 is rotatably mounted between the two sides of the inner wall of the U-shaped frame 170. A sixth bevel gear is symmetrically fixedly mounted on the fourth rotating shaft 172, and the sixth and fifth bevel gears are meshed together. A second motor 173 is fixedly mounted on one end of the fourth rotating shaft 172. This achieves precise control of the rotation of the threaded rod 161, thereby enabling precise adjustment of the lifting height of the catalyst membrane 131. The U-shaped frame 170 provides a stable support structure for each shaft and bevel gear, ensuring the stability of the transmission process, reducing component wear, and extending the service life of the device.

[0027] Working principle: Open the valve on the inlet pipe 111, and the water to be treated will be pumped into the reaction tank 110 through the inlet pipe 111. The valves on the inlet pipe 111 and the outlet pipe 112 can control the flow of water, which facilitates the operation, management and maintenance of the device.

[0028] Aeration stage: Air or a specific reactive gas enters through the air inlet at one end of the aeration pipe 140. The aeration pipe 140 is serpentine in shape and fixed to the inner wall of the reaction tank 110. Its surface has multiple air outlets. A waterproof and breathable membrane on the inner wall of the air outlets prevents backflow. There is a gap between the aeration pipe 140 and the bottom of the inner wall of the reaction tank 110. Air is discharged from the air outlets, forming microbubbles at the bottom of the reaction tank 110, increasing the dissolved oxygen content in the water and providing the necessary conditions for subsequent membrane catalytic reactions. Simultaneously, the rising bubbles drive water flow, promoting mixing.

[0029] Mixing stage: The first motor 154 is started, driving the second rotating shaft 152 to rotate. The second bevel gear on the second rotating shaft 152 meshes with the first bevel gear at one end of the first rotating shaft 150, causing the first rotating shaft 150 to rotate. The stirring rod 151 on the first rotating shaft 150 rotates accordingly, stirring the water in the reaction tank 110, further promoting water mixing, and ensuring that the water to be treated comes into full contact with dissolved oxygen and the catalytic membrane 131, thereby improving reaction efficiency. The first rotating shaft 150 is located above the aeration pipe 140, and the two work together to optimize the water flow.

[0030] Membrane catalytic reaction stage: Under the action of aeration and stirring, the water to be treated comes into full contact with the catalytic membrane 131. The catalytic membrane 131 is inserted into the inner wall of the support frame 130. The inner wall of the support frame 130 has grooves and support strips. The catalytic membrane 131 is sealed and slidably installed between the support strips to ensure effective contact between the water flow and the catalytic membrane 131. New pollutants in the water undergo decomposition reactions under the action of the catalytic membrane 131, transforming into harmless or less harmful substances. The guide plate 134 between the two support frames 130 is on the same plane as the partition plate 113, which can guide the water flow direction and make the water flow more evenly through the catalytic membrane 131.

[0031] Catalytic membrane lifting and maintenance: If maintenance or replacement of the catalytic membrane 131 is required, the second motor 173 is started. The second motor 173 drives the fourth rotating shaft 172 to rotate. The sixth bevel gear on the fourth rotating shaft 172 meshes with the fifth bevel gear on the third rotating shaft 171, causing the third rotating shaft 171 to rotate. The fourth bevel gear on the third rotating shaft 171 meshes with the third bevel gear at the top of the threaded rod 161, causing the threaded rod 161 to rotate. The bracket 160 is threaded onto the threaded rod 161 and slidably mounted on the guide rod 162. As the threaded rod 161 rotates, the bracket 160 rises or falls within the lifting chamber, thereby causing the support plate 133, the support rod 132, the support frame 130, and the catalytic membrane 131 to rise or fall, facilitating operation of the catalytic membrane 131.

[0032] Water discharge stage: The treated water is discharged from the reaction tank 110 through the water outlet pipe 112. The treated water can flow out by opening the valve on the water outlet pipe 112, thus completing the entire water treatment process.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
