Abstract
Description
Technical Field
[0001] This utility model relates to the field of aeration diffuser technology, specifically an integrated wastewater treatment energy-saving aeration diffuser. Background Technology
[0002] Aeration diffusers are key components in wastewater treatment processes, enabling water oxygenation and improving biochemical treatment efficiency. They are widely used in integrated wastewater treatment equipment, and their aeration uniformity, operational stability, and energy consumption directly impact the overall treatment effect and operating costs. Current industry research on the structural design and energy-saving optimization of aeration diffusers focuses primarily on gas delivery, bubble diffusion, and pipeline control, aiming to reduce equipment energy consumption, extend service life, and ensure the stability of aeration diffusion.
[0003] Traditional aeration diffusers mostly use a fixed installation structure for the diffuser plates, which is cumbersome to install and remove. After long-term use, impurities easily accumulate on the surface and micropores of the diffuser plates, making them difficult to clean and replace, thus affecting the aeration and diffusion effect. At the same time, existing aeration devices mostly rely on a fixed-opening air supply structure, which cannot adjust the air supply in real time according to changes in pipeline pressure, easily leading to unstable air supply or high energy consumption. Furthermore, some aeration structures with backflushing functions require additional air storage devices, which not only increases equipment costs and installation space, but also makes it difficult for the backflushing airflow to fully cover the micropore area of the diffuser plate, easily causing local blockage and a decrease in diffusion efficiency.

The check valve 5 can prevent gas backflow.
[0029] Please see Figure 1 The protective shell 6 is located at the top of the gas transmission pipe 2. A disc-shaped diffuser plate 7 is provided on the upper surface of the protective shell 6.

[0030] The positioning frame 8 can compress the disc diffuser plate 7. The positioning frame 8 is fixed to the surface of the protective shell 6 by the threaded rod 9, which can be used to install the disc diffuser plate 7. The positioning frame 8 can be disassembled by removing the threaded rod 9, which can then be used to disassemble the disc diffuser plate 7, making it convenient to clean and replace the disc diffuser plate 7.
[0031] Please see Figure 1 Connecting pipe 10 is located above aeration pipe 1. Please refer to [link / reference]. Figure 2 An air pump 11 is installed at the outlet end of the connecting pipe 10, and an air inlet pipe 12 is provided at the outlet end of the air pump 11. Please refer to [link / reference]. Figure 3 The air outlet of the air inlet pipe 12 is equipped with a back-blowing frame 13. The back-blowing frame 13 is a ring-shaped design and is located inside the protective shell 6. The upper surface of the back-blowing frame 13 is evenly distributed with first back-blowing nozzles 14, the upper surface edge of the back-blowing frame 13 is evenly distributed with second back-blowing nozzles 15, and the inner wall of the back-blowing frame 13 is evenly distributed with third back-blowing nozzles 16. Both the second back-blowing nozzles 15 and the third back-blowing nozzles 16 are inclined designs.
[0032] Starting the air pump 11 draws the gas from the aeration pipe 1 into the air inlet pipe 12, eliminating the need for an external air storage tank and saving costs. At the same time, the backflush frame 13 injects the gas into the backflush nozzles. Through the first backflush nozzle 14, the second backflush nozzle 15, and the third backflush nozzle 16, the gas can be sprayed out evenly, covering all the micropores of the disc diffuser plate 7. This blows out impurities from the micropores of the disc diffuser plate 7, preventing the disc diffuser plate 7 from becoming clogged and improving the diffusion effect of the disc diffuser plate 7.
[0033] Please see Figure 2 The inlet end of the gas pipeline 2 is equipped with a first flange 17. Please refer to [link / reference]. Figure 6 A second flange 18 is installed on the upper surface of the aeration pipe 1 at a position corresponding to the first flange 17. The first flange 17 and the second flange 18 are used to connect the air supply pipe 2 to the aeration pipe 1.
[0034] Please see Figure 3 The air inlet end of the connecting pipe 10 is equipped with a third flange 19. Please refer to [link / reference].

The surface of the air inlet pipe 12 is equipped with a pressure reducing valve 22, and the inner wall of the pressure reducing valve 22 is also equipped with a pressure sensor 3. The pressure reducing valve 22 can control the backflush pressure according to the pressure detected by the pressure sensor 3.

The sealing ring 23 can seal the space between the first flange 17 and the second flange 18, and between the third flange 19 and the fourth flange 20.
[0037] Please see Figure 4 A sealing ring 24 is installed at the bottom of the disc diffuser plate 7, and a sealing groove 25 is provided on the upper surface of the protective shell 6. The sealing ring 24 is inserted into the sealing groove 25 to seal the connection between the disc diffuser plate 7 and the protective shell 6.
[0038] In operation, this solution works as follows: First, the positioning frame 8 compresses the disc diffuser plate 7. The threaded rod 9 secures the positioning frame 8 to the surface of the protective shell 6, allowing for the installation of the disc diffuser plate 7. Removing the threaded rod 9 allows for the disassembly of the positioning frame 8, thus facilitating the removal of the disc diffuser plate 7 for cleaning and replacement. Then, the pressure sensor 3 monitors the pressure within the gas channel in real time. Based on the pressure signal from the pressure sensor 3, the opening of the flow regulating valve 4 is automatically adjusted to ensure gas stability. For efficient supply and energy-saving operation, the check valve 5 prevents backflow of gas. Finally, the air pump 11 draws the gas from the aeration pipe 1 into the air inlet pipe 12, eliminating the need for an external air storage tank and saving costs. At the same time, the backflush frame 13 injects gas into the backflush nozzles. The first backflush nozzle 14, the second backflush nozzle 15, and the third backflush nozzle 16 can evenly spray the gas, covering all the micropores of the disc diffuser plate 7. This blows out impurities from the micropores of the disc diffuser plate 7, preventing blockage and improving the diffusion effect of the disc diffuser plate 7.
