Description

Technical Field

[0001] This utility model relates to the technical field of aeration tank equipment for sewage treatment, and in particular to a cooling device for aeration pipes. Background Technology

[0002] An aeration pipe is a device used to inject air or oxygen into wastewater to increase the dissolved oxygen content in the wastewater, providing a sufficient oxygen environment for microorganisms, thereby accelerating the biodegradation process of organic pollutants.

[0003] Compressed air is delivered to the aeration pipes through pipelines and then released through the numerous micropores on the surface of the aeration pipes, forming a large number of tiny, uniform bubbles. These bubbles rise slowly in the water, making full contact with the surrounding water, significantly increasing the contact area between the gas and liquid phases, thereby improving the efficiency of oxygen transfer from the gas phase to the liquid phase and achieving efficient oxygenation. To enhance the activity of microorganisms, the compressed air needs to be cooled to prevent excessively high temperatures in the wastewater tank. Currently, compressed air cooling is mainly achieved through water-cooled shell-and-tube coolers. However, because the cooling water flows continuously inside the tubes, and there is a significant temperature difference between the water and the tube wall, especially in areas with hard water (high calcium and magnesium ion content), scale easily forms on the inner wall of the tubes. Over time, the scale gradually thickens, significantly reducing the effective pipe diameter and causing a decrease in cooling water flow, requiring regular cleaning. Cleaning requires manual disassembly, chemical cleaning, or high-pressure water jet unblocking; the entire process is time-consuming and labor-intensive, requiring system shutdown and increasing maintenance costs.

[0004] Therefore, those skilled in the art are dedicated to developing an aeration pipe cooling device that not only reduces the temperature of compressed air but also reduces scale buildup on the pipe walls. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an aeration pipe cooling device that not only reduces the temperature of compressed air, but also reduces scale buildup on the water pipe wall.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An aeration pipe cooling device, comprising: A cooling box having oppositely disposed openings, the ends of which are used for connection to aeration pipes; A water inlet pipe assembly is installed inside the cooling tank, and both ends of the water inlet pipe assembly are respectively connected to a water inlet manifold and a water return manifold; A water outlet pipe assembly is installed inside the cooling tank, and both ends of the water outlet pipe assembly are respectively connected to a water outlet manifold and a water return manifold; A first anti-scaling component is installed on the inlet pipe assembly and the outlet pipe assembly, and the first anti-scaling component is electrically connected to a control component. The second anti-scaling component is installed at the end of the water inlet pipe assembly and is electrically connected to the control assembly.

[0007] The beneficial effects of adopting the above scheme are: efficient cooling of the aeration pipe is achieved through the cooling tank, inlet pipe assembly, and outlet pipe assembly, and the first and second anti-scaling components work together to effectively prevent scale formation in the cooling water and extend the service life of the equipment.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the first anti-scaling component includes an ultrasonic generator, which is sleeved in the middle of the inlet pipe and the outlet pipe, and is electrically connected to the control component.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: the high-frequency vibration generated by the ultrasonic waves propagating on the pipe wall can prevent the cooling water from forming scale on the pipe wall, or the generated high-frequency vibration can effectively break up and peel off the scale that has already formed.

[0017] Furthermore, the second anti-scaling component includes an anti-scaling tube and an electronic magnetic water device. The anti-scaling tube communicates with the water inlet manifold, and the electronic magnetic water device is installed on the anti-scaling tube and electrically connected to the control component.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it uses electromagnetic fields to change the physical state of calcium and magnesium ions in water, making them less likely to combine into hard scale, thus further enhancing the scale prevention effect.

[0019] Furthermore, the inlet end of the anti-scaling pipe is connected to an electrically controlled three-way valve, which is connected to the outlet pipe assembly; The cooling box is equipped with a temperature sensor for detecting the temperature of the cooling air.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1 , Figure 2 As shown, an aeration pipe cooling device includes: Cooling box 1 has an opening 2 that is arranged opposite to it. The end of the opening 2 is used to connect with the aeration pipe. The connection between the end of the opening 2 and the aeration pipe is usually provided with a sealing ring to ensure the airtightness of the cooling device and prevent compressed air leakage. The water inlet pipe assembly 3 is installed inside the cooling box 1, and the two ends of the water inlet pipe assembly 3 are respectively connected to the water inlet manifold 4 and the water return manifold 5. Cooling water flows into the water inlet manifold 4, then flows through the water inlet pipe assembly 3 and gathers into the water return manifold 5. The water outlet pipe assembly 6 is installed inside the cooling box 1, and the two ends of the water outlet pipe assembly 6 are respectively connected to the water outlet manifold 7 and the water return manifold 5. The cooling medium flows into the water outlet pipe assembly 6 from the water return manifold 5 and is finally discharged from the water outlet manifold 7, forming a complete cooling cycle. The first anti-scaling component 8 is installed on the inlet pipe assembly 3 and the outlet pipe assembly 6, and is electrically connected to a control component (not shown in the figure). The first anti-scaling component 8 is used to prevent or remove scale formed by the cooling medium on the inner wall of the pipe. The second anti-scaling component 9 is installed at the end of the inlet pipe assembly 3 and is electrically connected to the control assembly. The first anti-scaling component 8 and the second anti-scaling component 9 work together to form multiple anti-scaling protections.

[0031] like Figure 1 , Figure 2 As shown, in some embodiments, the water inlet pipe assembly 3 includes a water inlet pipe 10, which can be made of copper or stainless steel. The water inlet pipe 10 is installed in the cooling box 1 and its two ends are respectively connected to the water inlet manifold 4 and the water return manifold 5. Cooling water is first introduced into the water inlet manifold 4, and then the cooling water is introduced into multiple parallel water inlet pipes 10.

[0032] The water outlet pipe assembly 6 includes a water outlet pipe 11, which is installed inside the cooling box 1 and its two ends are connected to the water outlet manifold 7 and the water return manifold 5, respectively. The cooling water discharged from the water inlet pipe 10 first enters the water return manifold 5, then flows into multiple parallel water outlet pipes 11, and finally enters the water outlet manifold 7 before being discharged. Both the inlet pipe 10 and the outlet pipe 11 are equipped with heat exchange fins 12. During the cooling process, the compressed air first contacts the outlet pipe 11 and the heat exchange fins 12 on the outlet pipe 11 for the first heat exchange, which lowers the temperature of the compressed air. Then, the compressed air contacts the inlet pipe 10 and the heat exchange fins 12 on the inlet pipe 10 for the second heat exchange. By using multiple heat exchanges, the heat exchange efficiency of the compressed air is improved. At the same time, the air first exchanges heat with the high-temperature return water and then with the low-temperature inlet water, which reduces the temperature difference and avoids excessive thermal stress in the inlet pipe 10 and the outlet pipe 11 due to the large temperature difference, thus extending the service life of the equipment.

[0033] Inspection pipes 17 are installed on both the outlet water collection chamber 7 and the return water collection chamber 5. The end of the inspection pipe 17 is connected to a plug. The inspection pipe 17 can be a high-strength transparent pipe, which facilitates regular inspection of the condition inside the chamber or opening the plug for unblocking and cleaning, as well as introducing chemical reagents into the inlet pipe assembly 3 and the outlet pipe assembly 6 for soaking and descaling, effectively shortening maintenance time.

[0034] like Figure 1 , Figure 2As shown, in another embodiment, the first anti-scaling component 8 includes an ultrasonic generator 13, which is sleeved in the middle of the inlet pipe 10 and the outlet pipe 11. The ultrasonic generator 13 is electrically connected to the control component. It uses the high-frequency vibration generated by the ultrasonic waves propagating in the inlet pipe 10 and the outlet pipe 11 to reduce the deposition of metal particles. The periodic high-frequency vibration effectively breaks up and peels off the scale particles that have been formed.

[0035] In this embodiment, the second anti-scaling component 9 includes an anti-scaling tube 14 and an electronic magnetic water device 15. The anti-scaling tube 14 is connected to the inlet manifold 4, and the electronic magnetic water device 15 is installed on the anti-scaling tube 14 and electrically connected to the control component. The electronic magnetic water device 15 uses an electromagnetic field of a specific frequency to change the physical state of calcium and magnesium ions in the cooling water, making them less likely to combine into hard scale, thereby inhibiting scale formation at the source. A filter 18 is also connected to the end of the anti-scaling tube 14. The filter 18 can be a Y-type filter, and the Y-type filter has a built-in compressed air backflushing device. Pressure sensors are installed at both the inlet and outlet ends of the filter 18. When the pressure difference between the two ends of the filter 18 exceeds a set value, it can promptly send a signal to the control component, prompting the filter 18 to automatically clean or replace the filter element, avoiding water flow obstruction due to blockage.

[0036] like Figure 1 , Figure 2 As shown, in some embodiments, the input end of the anti-scaling pipe 14 is connected to an electrically controlled three-way valve 16, which is connected to the outlet water pipe assembly 6. A temperature sensor for detecting the cooling air temperature is installed inside the cooling tank 1. The control assembly can automatically adjust the opening of the electrically controlled three-way valve 16 according to the actual temperature of the air at the outlet of the aeration pipe detected by the temperature sensor, thereby adjusting the mixing ratio of high-temperature return water and low-temperature inlet water, realizing intelligent and precise control of cooling intensity, avoiding energy waste and ensuring cooling effect.

[0037] In other embodiments, a water quality monitoring system is installed between the inlet manifold 4 and the return manifold 5, specifically including a water quality sensor and a data acquisition module. The water quality sensor is used to monitor parameters such as hardness, pH value, and conductivity of the cooling water in real time, and the data acquisition module transmits these data to the control component. Based on the water quality data, the control component automatically adjusts the operating parameters of the electronic magnetic water heater 15 to ensure the anti-scaling effect. When the water hardness exceeds the set value, the system automatically increases the magnetic field strength of the electronic magnetic water heater 15 to prevent scale formation; when the water hardness is lower than the set value, the system automatically reduces the magnetic field strength to reduce energy consumption.
