Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a combined aeration device. Background Art

[0002] In the field of water treatment, aeration systems, as core equipment in activated sludge wastewater treatment processes, play a vital role in increasing the dissolved oxygen content in wastewater, promoting microbial activity, and accelerating the decomposition of organic pollutants. Traditional aeration systems mostly use rigid aerators, which have certain limitations in installation and maintenance. This is especially true when building new water plants or upgrading existing ones. The following technical issues arise:

[0003] First, when existing water plants need to be renovated and expanded without interrupting service, traditional rigid aerators are particularly difficult to meet. Because the normal operation of the water plant must be ensured during the renovation process, the removal and reinstallation of rigid aerators often results in long water outages, causing inconvenience to surrounding residents and businesses, and even potentially resulting in economic losses.

[0004] Secondly, traditional aeration systems also have shortcomings in gas distribution and regulation. Due to the lack of independent gas distribution and regulation mechanisms between aerators, it is often difficult to achieve precise air supply and gas volume regulation for each aeration membrane. This not only affects the aeration effect, but also may lead to energy waste and increased operating costs. Utility Model Content

[0005] In order to solve the technical problems of how to meet the non-stop water installation requirements when existing water plants need to be renovated and expanded without water interruption, and the deficiencies in gas distribution and regulation of traditional aeration systems, the utility model proposes a combined aeration device with a simple structure and easy operation. It combines and installs multiple flexible aeration membranes to meet the needs of non-stop water transformation and expansion of water plants, and realizes precise air supply and gas volume regulation for each aeration membrane. This not only meets the aeration effect, but also achieves efficient energy utilization and reduces operating costs.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows:

[0007] The utility model provides a combined aeration device, comprising: an aeration membrane support, a plurality of flexible aeration membranes connected to the aeration membrane support to form an aeration membrane bed, an aeration membrane air inlet provided on the flexible aeration membrane, the aeration membrane air inlet being connected to a first aeration branch pipe, the first aeration branch pipe being connected to one end of a first aeration branch pipe connector, the other end of the first aeration branch pipe connector being connected to a gas distributor.

[0008] The utility model proposes a combined aeration device with a simple structure and easy operation. It combines and installs multiple flexible aeration membranes, which can meet the needs of water plant non-stop transformation and expansion, and realize precise air supply and air volume regulation of each aeration membrane. This not only meets the aeration effect, but also realizes efficient use of energy and reduces operating costs.

[0009] As a preferred technical solution, the aeration membrane support includes: a plurality of fixing tubes, which are detachably connected by tube clamps to form a plurality of flexible aeration membrane fixing grooves, and the flexible aeration membranes are arranged in and connected to the flexible aeration membrane fixing grooves.

[0010] As a preferred technical solution, the aeration membrane bed is connected to the aerobic tank via a membrane bed fixing steel cable.

[0011] As a preferred technical solution, it includes: a second aeration branch pipe, one end of which is connected to the aeration main pipe, and the other end of which is connected to the gas distributor.

[0012] As a preferred technical solution, the other end of the first aeration branch pipe connector is connected to the gas distributor, and the other end of each of the first aeration branch pipe connectors is provided with a first aeration branch pipe connection port, and one end of the first aeration branch pipe connector is connected to the gas distributor through the first aeration branch pipe connection port.

[0017] As a preferred technical solution, the shape of the first aeration branch pipe connecting piece is an inverted "L" shape.

[0018] The utility model provides a combined aeration device, which has the following beneficial effects:

[0019] 1) It has a simple structure and is easy to operate. It can combine and install multiple flexible aeration membranes to meet the needs of water plants for non-stop water supply renovation and expansion, and achieve precise air supply and air volume regulation for each aeration membrane. This not only meets the aeration effect, but also achieves efficient energy utilization and reduces operating costs.

[0020] 2) The aeration membrane bracket and flexible aeration membrane adopt a modular design, which can be easily assembled and disassembled to meet the needs of water plant renovation and expansion without water outage. This design makes the installation and replacement of aeration membranes simpler and faster, reducing downtime and maintenance costs. The gas distributor is connected to the first aeration branch pipe through the first aeration branch pipe connector, ensuring uniform distribution and stable gas delivery. This connection method makes the gas supply more reliable and also facilitates precise gas volume adjustment for each aeration membrane.

[0021] 3) The flexible aeration membrane is provided with an aeration membrane air inlet. When the gas distributor delivers gas to the aeration membrane air inlet through the first aeration branch pipe connector and the first aeration branch pipe, the gas forms tiny bubbles within the aeration membrane and is released into the water body due to the vibration or diffusion of the aeration membrane. These tiny bubbles can greatly increase the gas-liquid contact area and improve the dissolution efficiency of oxygen. The precise design of the gas distributor and aeration membrane support can ensure that the gas is evenly distributed in the water body, avoiding local hypoxia or excessive aeration, and improving the stability of the entire treatment system.

The fixing tubes 18 serve as the main structure of the aeration membrane support 1 and provide stable support for the flexible aeration membrane 2; this ensures that the flexible aeration membrane 2 will not be displaced or deformed due to the impact force of water flow or bubbles during use, thereby ensuring the stability and durability of the aeration effect; the fixing tubes 18 are detachably connected together by the tube clamps 19 to form multiple flexible aeration membrane fixing grooves. These flexible aeration membrane fixing grooves can tightly fix the flexible aeration membrane 2 to prevent it from falling off or loosening during operation, further enhancing the stability and reliability of the combined aeration device; the detachable pipe clamp 19 connection method makes the installation process of the aeration membrane bracket 1 simpler and faster; the staff can easily assemble the fixing pipe 18 into the required shape and size according to needs, and then place the flexible aeration membrane 2 into the flexible aeration membrane fixing groove and fix it to complete the installation of the combined aeration device; when the flexible aeration membrane 2 is damaged or needs to be replaced, the staff can easily remove the pipe clamp 19 and the fixing pipe 18, take out the damaged flexible aeration membrane 2 and replace it with a new flexible aeration membrane 2; this design not only simplifies the maintenance process, but also reduces maintenance costs and time.

[0032] Preferably, if Figure 2 As shown, the aeration membrane bed 5 is connected to the aerobic tank 8 by a membrane bed fixing steel cable 7; the membrane bed fixing steel cable 7 firmly connects the aeration membrane bed 5 to the aerobic tank 8, providing stable support for the aeration membrane bed 5; this design ensures that the aeration membrane bed 5 will not be displaced or deformed due to the impact force of water flow or bubbles during the aeration process, thereby ensuring the stability and durability of the aeration effect; the stable support also helps to reduce the vibration and noise of the aeration membrane bed 5, and improve the operating efficiency of the entire aeration system; the aeration membrane bed 5 is connected to the aerobic tank 8 by the membrane bed fixing steel cable 7, making the installation process simpler and faster; the staff can easily place the aeration membrane bed 5 in a suitable position according to needs, and fix it with the membrane bed fixing steel cable 7; at the same time, this design also facilitates subsequent maintenance and replacement work; when the aeration membrane bed 5 needs to be repaired or replaced, the staff can easily disassemble the membrane bed fixing steel cable 7, take out the aeration membrane bed 5 and carry out corresponding treatment.

[0033] Preferably, if Figure 4As shown, it includes: a second aeration branch pipe 15, one end of which is connected to the aeration main pipe 14, and the other end of the second aeration branch pipe 15 is connected to the gas distributor 9; the second aeration branch pipe 15 is a key component in the aeration system, one end of which is connected to the aeration main pipe, and the other end is connected to the gas distributor 9; this connection method ensures that the gas can be smoothly transported from the aeration main pipe to the gas distributor 9, thereby providing sufficient gas source for the subsequent aeration process; through the transportation of the second aeration branch pipe 15, the gas distributor 9 can receive a stable airflow from the aeration main pipe; the gas distributor 9 then evenly distributes these airflows to each flexible aeration membrane 2, thereby ensuring uniform gas distribution in the entire aeration area and improving the aeration efficiency.

[0034] Preferably, if Figure 3-4 As shown, the other end of the first aeration branch pipe connector 10 is connected to the gas distributor 9, and the other end of each of the first aeration branch pipe connectors 10 is provided with a first aeration branch pipe connecting port (not shown), and one end of the first aeration branch pipe connector 10 is connected to the gas distributor 9 through the first aeration branch pipe connecting port (not shown); the other end of each first aeration branch pipe connector 10 is provided with a first aeration branch pipe connecting port (not shown), and is connected to the gas distributor 9 through the first aeration branch pipe connecting port (not shown); such a design ensures that the gas can be smoothly transported from the gas distributor 9 to each first aeration branch pipe 6, thereby providing a stable gas source for the subsequent aeration process; at the same time, such a connection method also facilitates maintenance and inspection of the aeration system. When the aeration branch pipe needs to be replaced or repaired, it is only necessary to remove the connector without making large-scale changes to the entire system.

[0035] Preferably, if Figure 3-4 As shown, each of the first aeration branch pipe connectors 10 is provided with a pressure gauge 12 and a valve 13; the pressure gauge 12 can monitor the gas pressure in the aeration branch pipe in real time to ensure that the pressure of the gas is stable during the transportation process; when the pressure is abnormal, the staff can promptly discover and take appropriate measures to adjust it, thereby avoiding system failure or damage; the design of the valve 13 allows the staff to easily control the opening and closing of the first aeration branch pipe 6, thereby achieving precise control of the aeration process; when it is necessary to adjust the aeration volume or stop aeration, it is only necessary to operate the corresponding valve 13.

[0036] Preferably, if Figure 4 As shown, one of the first aeration branch pipe connectors 10 is further provided with a safety valve 16 ; the safety valve 16 is an important safety device that can be opened to release excess gas when the system pressure is too high, thereby protecting the system from damage.

[0037] Preferably, if Figure 4As shown, one of the first aeration branch pipe connectors 10 is provided with an air vent 17 at the other end; the air vent 17 is designed mainly to conveniently discharge residual gas in the aeration branch pipe when the system is shut down or maintained; this helps to avoid gas accumulation inside the system and cause potential safety hazards.

[0038] Preferably, if Figure 1 As shown, the aeration membrane air inlet is combined with the first aeration branch pipe to form an air inlet pipe; the main function of the air inlet pipe 4 is to transport compressed air or other gas into the interior of the aeration membrane 2, and enter the interior of the aeration membrane 2 through the aeration membrane air inlet 3. The gas diffuses into the water phase to form tiny bubbles. The bubble area is small and the rising speed at the bottom of the water is slow. The contact time between the bubbles and the water is longer, so the oxygen transfer efficiency is better.

[0039] Preferably, if Figure 3 As shown, the first aeration branch pipe connector 10 is in the shape of an inverted "L"; the inverted "L" shape design allows the gas to flow along a more reasonable path when flowing through the first aeration branch pipe connector 10; this design helps to reduce the resistance and eddy current of the gas inside the first aeration branch pipe connector 10, thereby improving the flow efficiency and stability of the gas; at the same time, the inverted "L"-shaped connector can also ensure that the gas has been fully dispersed and evenly distributed before entering the aeration branch pipe, which is conducive to the smooth progress of the subsequent aeration process.
