[0025] The following Figure 1 and Figure 2 , through specific embodiments and their application scenarios, will elaborate in detail on an enhanced efficiency and anti-blocking wastewater aeration treatment device provided by the embodiments of the present invention.

[0026] In the embodiments of the present invention, as Figure 1 and Figure 2As shown, "An enhanced efficiency anti-blocking wastewater aeration treatment device 10 includes a housing body 100 and an aeration mechanism 200. The housing body 100 has a treatment chamber 110, a feed inlet 120 and a discharge outlet 130 that communicate with the treatment chamber 110; the aeration mechanism 200 is arranged around the inner wall of the treatment chamber 110 and is located in the middle and lower part of the treatment chamber 110. The aeration mechanism 200 includes a plurality of elastic aerators 210, and the plurality of elastic aerators 210 are arranged at intervals along the circumferential direction of the treatment chamber 110. Each elastic aerator 210 is provided with a plurality of air inlets 211." Explain in detail the function of each technical feature in the above technical solution in the technical solution.

[0027] The housing body 100 is the main structure of the entire wastewater aeration treatment device, providing a closed space for the treatment process and ensuring the safety and effectiveness of wastewater treatment.

[0028] The housing body 100 has a treatment chamber 110, a feed inlet 120 and a discharge outlet 130 that communicate with the treatment chamber 110 to allow wastewater to enter the treatment chamber 110 and be discharged after treatment is completed.

[0029] The treatment chamber 110 is the main place for wastewater aeration treatment. It houses the wastewater to be treated and the aeration mechanism 200, providing the necessary space for the aeration process.

[0030] The feed inlet 120 is used to introduce the wastewater to be treated into the treatment chamber 110, and the discharge outlet 130 is used to discharge the treated wastewater from the device.

[0031] The aeration mechanism 200 is responsible for introducing carbon dioxide into the washing liquid to form carbonic acid. The calcium ions in the fly ash react with the carbonic acid to form calcium carbonate precipitation, fixing the calcium ions, reducing the hardness and viscosity of the solution, and facilitating subsequent disposal.

[0032] The aeration mechanism 200 is arranged around the inner wall of the treatment chamber 110, and this layout helps to improve the uniformity and efficiency of aeration.

[0033] Setting the aeration mechanism 200 in the middle and lower part of the treatment chamber 110 can reduce the chance of sediment directly falling on the aerator, thereby reducing the risk of blockage. It helps to keep the aerator clean and extend its service life.

[0034] The elastic aerator 210 can adjust its shape according to the change of the wastewater liquid level, thereby maintaining an effective aeration effect. These aerators are arranged at intervals along the circumferential direction of the treatment chamber 110, ensuring the uniform distribution of gas throughout the treatment chamber 110.

[0035] The elastic aerators 210 are arranged at circumferential intervals along the inner wall of the treatment chamber 110, which helps to achieve uniform distribution of gas in the wastewater and improve the aeration efficiency. And by arranging at circumferential intervals, the aerators can cover a larger area and enhance the gas-liquid contact.

[0036] Each elastic aerator 210 is provided with a plurality of air inlets 211. The plurality of air inlets 211 can increase the channels for gas to enter the liquid and improve the gas-liquid mixing effect. The design of the air inlets 211 enables the gas to enter the liquid from different directions, enhancing the uniformity and efficiency of mixing.

[0037] In this application, the aeration mechanism 200 is arranged in a ring shape on the inner wall of the treatment chamber 110 and is located in the middle and lower part of the treatment chamber 110. The elastic aerators 210 are not installed at the bottom of the treatment chamber 110, but are arranged at the middle and lower part of its inner wall. This reduces the risk of sediment freely falling and settling on the surface of the elastic aerators 210, thereby reducing the risk of blockage of the air inlets 211 caused by sediment deposition. At the same time, the plurality of elastic aerators 210 are arranged at circumferential intervals along the inner wall of the treatment chamber 110, ensuring uniform distribution of gas throughout the treatment chamber 110, thereby improving the uniformity of gas-liquid mixing within the entire volume range. And the plurality of air inlets 211 on each elastic aerator 210 further increase the contact points between the gas and the liquid, enabling the gas to enter the liquid from different directions and enhancing the gas-liquid mixing effect.

[0038] Refer to Figure 1 , according to an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 provided by the present invention, the aeration mechanism 200 further includes a gas pipeline 220, and the gas pipeline 220 is respectively communicated with the elastic aerators 210 through branch pipes 230.

[0039] It can be understood that the gas pipeline 220, as the main gas transmission trunk line of the entire aeration mechanism 200, can centrally introduce the gas generated by the external gas source into the treatment chamber 110 to ensure stable gas supply.

[0040] By connecting the gas pipeline 220 with each elastic aerator 210 through the branch pipes 230, uniform distribution of gas within the treatment chamber 110 is achieved. The design of the branch pipes 230 can be reasonably arranged according to the positions and quantities of the elastic aerators 210 to ensure that each elastic aerator 210 can obtain relatively stable and appropriate gas supply. This uniform distribution method helps to improve the uniformity of gas-liquid mixing, enabling the pollutants in the wastewater to come into contact with the gas more fully, thereby improving the treatment effect.

[0041] Refer to Figure 1 and Figure 2, according to an enhanced anti-clogging wastewater aeration treatment device 10 provided by the present invention, the elastic aerator 210 is arranged in a flat-bottom convex hemisphere structure. When gas flows through the elastic aerator 210 in the liquid, the elastic aerator 210 can bounce to prevent sediment from adhering to the surface of the elastic aerator 210.

[0042] It can be understood that the flat-bottom convex hemisphere structure enables the gas to be released uniformly and in multiple directions from its convex surface during the aeration process of the elastic aerator 210. Compared with traditional flat or simple curved surface aerators, this structure increases the contact area and contact angle between the gas and the wastewater, enabling the gas to be more quickly and evenly dispersed into the wastewater, thereby improving the transfer efficiency of carbon dioxide and the generation rate of carbonic acid, allowing the calcium ions in the wastewater to react more fully to form calcium carbonate, and further enhancing the efficiency of wastewater treatment.

[0043] The surface of the flat-bottom convex hemisphere structure is relatively smooth without excessive edges and depressions, which makes it difficult for impurities (such as suspended solids, flocs, etc.) in the wastewater to adhere and accumulate on its surface.

[0044] Refer to Figure 1 and Figure 2 , according to an enhanced anti-clogging wastewater aeration treatment device 10 provided by the present invention, a plurality of air inlets 211 are arranged on the convex surface of the elastic aerator 210.

[0045] It can be understood that arranging a plurality of air inlets 211 on the convex surface of the elastic aerator 210 enables the gas to enter the interior of the treatment chamber 110 from different directions by the aerator. Compared with the design where the air inlets 211 are concentrated at a certain specific position (such as a single position at the bottom or side), this multi-directional air inlet method can make the gas more evenly distributed inside the treatment chamber 110. When the gas enters from each air inlet 211, a relatively uniform airflow field will be formed inside the treatment chamber 110, effectively improving the uniformity of gas-liquid mixing, ensuring that all areas in the wastewater can fully contact the gas, and enhancing the overall treatment efficiency.

[0046] Refer to Figure 1 and Figure 2 , according to an enhanced anti-clogging wastewater aeration treatment device 10 provided by the present invention, the air inlet 211 is arranged in a fan shape.

[0047] It can be understood that the fan-shaped air inlet 211 can make the gas more evenly dispersed when entering the wastewater because the fan-shaped structure helps the gas to be released simultaneously in multiple directions, thereby generating small bubbles in more directions and improving the dispersibility of the gas.

[0048] The design of the fan-shaped air inlet 211 increases the contact area between the gas and the liquid, making it easier for the bubbles to diffuse in the liquid and improving the dissolution efficiency of carbon dioxide or other gases in the wastewater.

[0049] Since the sector-shaped air inlet 211 can provide gas flow in multiple directions, this helps to achieve uniform aeration of the wastewater in the treatment chamber 110, reduce dead zones in aeration, and improve the overall treatment effect.

[0050] Refer to Figure 1 , according to an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 provided by the present invention, the enhanced efficiency and anti-blocking wastewater aeration treatment device 10 further includes a stirring mechanism 300, and the stirring mechanism 300 is used to promote the mixing and contact of gas and liquid, and stir the sediment inside the treatment chamber 110.

[0051] It can be understood that the stirring mechanism 300 can effectively stir the sediment inside the treatment chamber 110, prevent it from accumulating at the bottom to form a thick layer, and reduce the decrease in aeration efficiency caused by sediment accumulation.

[0052] Meanwhile, through stirring, the sediment is dispersed and kept in a suspended state, and it is not easy to settle on the aeration unit, thus avoiding the blockage problem of the air inlet 211.

[0053] The stirring mechanism 300 makes the sediment mix more evenly with the wastewater, helps the gas to be better dispersed into the wastewater, and improves the aeration efficiency and carbon dioxide transfer rate.

[0054] Refer to Figure 1 , according to an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 provided by the present invention, the stirring mechanism 300 includes a stirrer 310, a stirring shaft 320 and a plurality of ultrasonic blades 330. The stirrer 310 is arranged at the top of the shell body 100, and the stirring shaft 320 extends along the axis direction of the treatment chamber 110. Among them, the upper end of the stirring shaft 320 penetrates through the shell body 100 and is connected to the stirrer 310, the lower end of the stirring shaft 320 extends to the bottom of the treatment chamber 110, and a plurality of ultrasonic blades 330 are connected to the lower end of the stirring shaft 320.

[0055] It can be understood that the arrangement of the stirrer 310 and the stirring shaft 320 realizes the mechanical stirring of the sediment at the bottom of the treatment chamber 110, preventing sediment accumulation and blockage.

[0056] The stirring shaft 320 extends along the axis direction of the treatment chamber 110, ensuring that the stirring effect can cover the entire bottom of the chamber and improving the uniformity of stirring.

[0057] The introduction of the ultrasonic blades 330 not only stirs the sediment through mechanical movement, but also further refines the bubbles by using the cavitation effect of ultrasonic waves, enhancing the stirring and mixing effects.

[0058] In some embodiments, an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 further includes a turbidity sensor disposed in the treatment chamber 110. The turbidity sensor is used to detect the turbidity of the liquid in the treatment chamber 110, and the turbidity sensor is communicatively connected to the stirring mechanism 300.

[0059] It can be understood that during the wastewater aeration treatment process, the turbidity of the wastewater will change with the treatment progress. By continuously and accurately measuring the turbidity of the wastewater with the turbidity sensor, intuitive data on the wastewater treatment effect can be obtained in a timely manner, providing a basis for subsequent control and adjustment.

[0060] The turbidity sensor is communicatively connected to the stirring mechanism 300, enabling real-time data transmission and feedback control. When the turbidity sensor detects a change in the turbidity of the wastewater, it will transmit a corresponding signal to the stirring mechanism 300. For example, if the turbidity is too high, it indicates that there are more suspended particles in the wastewater, and there may be a risk of blockage or poor treatment effect. At this time, the stirring mechanism 300 can adjust the stirring parameters according to the received signal, such as increasing the stirring speed or changing the stirring mode, to enhance the stirring and mixing effect of the wastewater, promote the dispersion of suspended particles, thereby improving the treatment effect and preventing blockage. Conversely, when the turbidity drops to a certain extent, the stirring mechanism 300 can appropriately reduce the stirring intensity to save energy.

[0061] Refer to Figure 1 , according to an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 provided by the present invention, an exhaust port 140 is provided at the top of the housing body 100. The exhaust port 140 is communicated with the treatment chamber 110, and the exhaust port 140 is used to relieve pressure on the treatment chamber 110.

[0062] It can be understood that during the wastewater treatment process, especially when a gas (such as carbon dioxide) is introduced into the liquid, certain gas accumulation will occur, resulting in an increase in the pressure inside the treatment chamber 110. The existence of the exhaust port 140 can release these excess gases in a timely manner, keeping the pressure inside the treatment chamber 110 within a safe and stable range, and avoiding equipment damage or unstable operation due to excessive pressure.

[0063] Refer to Figure 1 , according to an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 provided by the present invention, the feed port 120 and the discharge port 130 are arranged offset from each other on opposite sides of the housing body 100, and the feed port 120 is disposed near the upper end of the housing body 100, and the discharge port 130 is disposed near the lower end of the housing body 100.

[0064] It can be understood that the offset arrangement of the feed port 120 and the discharge port 130 can promote the circulation of the water flow in the treatment chamber 110, contribute to increasing the contact time between the wastewater and the aeration bubbles, and thus enhance the carbon dioxide transfer efficiency.

[0065] The feed inlet 120 is located at the upper end of the shell body 100, which can enable the wastewater to have a certain flow rate when entering the treatment chamber 110, helping to disperse the suspended solids; while the discharge outlet 130 is located at the lower end, which can utilize the gravity to further sediment the precipitate before flowing out.

[0066] In this way, by arranging the feed inlet 120 and the discharge outlet 130 staggeredly, the short-circuit flow phenomenon that the wastewater directly flows from the feed inlet 120 to the discharge outlet 130 can be reduced, ensuring that the wastewater has sufficient residence time in the treatment chamber 110 for full treatment.

[0067] Refer to Figure 1 , in a specific embodiment, the shell body 100 of an enhanced efficiency and anti-blocking wastewater aeration treatment device 10 is cylindrical, with a feed inlet 120 opened near the upper end and a discharge outlet 130 opened near the lower end. The gas pipeline 220 coils around once at a distance of 400 mm from the bottom inside the device, and an air outlet is provided every 500 mm. The air outlet is connected to the elastic aerator 210 through a branch pipe 230. The high-salt wastewater enters the treatment chamber 110 from the feed inlet 120, and carbon dioxide enters the interior of the treatment chamber 110 through the fan-shaped air inlet 211 on the elastic aerator 210, and the gas-liquid mixture is aerated. During the aeration process, the stirrer 310 keeps slowly and evenly stirring, promoting the mixing and reaction of the gas and the wastewater. The stirrer 310 is provided with ultrasonic blades 330, and the ultrasonic blades 330 are of a cavity structure. Ultrasonic waves are emitted from the cavity. The ultrasonic device runs intermittently, and the ultrasonic waves are triggered in real time by a turbidity sensor, and the ultrasonic waves continue to work for 1 - 2 minutes after the aeration device stops, preventing the precipitate from solidifying. During the stirring process, the ultrasonic waves on the blades disrupt the sedimentation of the reaction products, further avoiding the blockage of the air inlet 211 of the elastic aerator 210 by the precipitate and improving the aeration effect. An exhaust port 140 is provided at the top of the device, and the excess gas after reacting with the wastewater is discharged from the exhaust port 140 to avoid excessive air pressure inside the device. The aerated wastewater is discharged from the discharge outlet 130 for further disposal or utilization.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
