Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an aerator cleaning system. Background Technology

[0002] Currently, municipal wastewater treatment commonly employs the activated sludge process, which relies on aerobic microorganisms in activated sludge to remove organic matter from wastewater. These aerobic microorganisms require oxygen to function properly, and the oxygenation efficiency in the aeration tank is positively correlated with the microbial growth. Insufficient oxygen supply leads to a decline in activated sludge performance and a decrease in wastewater treatment effectiveness. Microporous aerators are widely used due to their high oxygen transfer efficiency, but prolonged use can cause scaling and clogging, resulting in increased pressure resistance, decreased aeration efficiency, increased energy consumption, and even damage to the aerators.

[0003] In existing technologies, to solve the problem of aerator clogging, regular cleaning with cleaning solutions is required. For example, formic acid is used for cleaning, as it effectively dissolves most of the scale buildup in the aeration pores. Furthermore, formic acid, as a cleaning solution, not only does not affect the growth process of activated sludge but can also serve as a nutrient source for it. However, most existing technologies employ semi-automatic or manual mobile dosing devices, using diaphragm pumps to deliver the chemicals. This results in low automation, and if the pressure is too high during operation, the chemicals may leak out through bypasses, causing environmental pollution and posing safety hazards to personnel.

[0027] The following is combined Figure 1 This invention describes the aerator cleaning system provided by this utility model.

[0028] See Figure 1 As shown in the figure, the aerator cleaning system provided in this embodiment of the present invention includes: a liquid storage device 100, a liquid delivery pipe 200 and a liquid delivery pump 300.

[0029] The storage device 100 is used to store the cleaning solution; the infusion tube 200 includes an infusion main tube 210 and multiple infusion branch tubes 220. The inlet end of the infusion main tube 210 is connected to the storage device 100, the inlet end of the infusion branch tubes 220 is connected to the infusion main tube 210, and the outlet ends of the multiple infusion branch tubes 220 are configured to be connected to multiple aerators 700 one by one; the infusion pump 300 is located in the infusion main tube 210.

[0030] The aerator cleaning system provided by this utility model, by setting up a liquid storage device 100, an infusion pipe 200 and an infusion pump 300, can use the infusion pump 300 to pump out the cleaning solution stored in the infusion device, and enter each infusion branch pipe 220 through the main infusion pipe 210. Since each infusion branch pipe 220 is configured to be connected to an aerator 700 in a one-to-one correspondence, it can automatically clean multiple aerators 700 at the same time, or control the opening and closing of each infusion branch pipe 220 to clean each aerator 700 independently. It has a high degree of automation and does not require manual intervention, which solves the defects of low automation and complicated operation when using semi-automatic or manual methods for adding medicine in the prior art.

[0031] Specifically, the aerator cleaning system provided by this utility model includes a liquid storage device 100, a delivery pipe 200, and a delivery pump 300. The liquid storage device 100 stores the cleaning solution. The delivery pipe 200 includes a main delivery pipe 210 and multiple delivery branch pipes 220 that are connected to each of the multiple aerators 700. The main delivery pipe 210 serves as the primary delivery channel, responsible for centrally delivering the cleaning solution, guiding it from the liquid storage device 100 to the multiple delivery branch pipes 220 distributed throughout the system. The delivery branch pipes 220 are respectively connected to their corresponding aerators 700 to introduce the cleaning solution into the aerators 700 for cleaning treatment. The number of delivery branch pipes 220 corresponds one-to-one with the number of aerators 700, thereby achieving cleaning treatment for multiple aerators 700. The infusion pump 300 is used to extract the cleaning solution from the storage device 100 and deliver it to each infusion branch pipe 220 through the infusion main pipe 210, and finally send the solution into each aerator 700 for cleaning.

[0032] The cleaning solution can be an acidic cleaning solution, an alkaline cleaning solution, or an enzyme-based cleaning agent. The specific cleaning solution selected depends on the nature of the dirt and the material of the aerator 700, and there are no special limitations. Formic acid is used as an example in this embodiment. The infusion tubing 200 is preferably made of a material with strong corrosion resistance, such as rigid polyvinyl chloride (UPVC), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polyethylene (PE), or fluoroplastics, and there are no special limitations. The infusion pump 300 is preferably a type capable of constant pressure infusion to form a stable liquid flow within the infusion tubing 200, avoiding the impact of fluctuations and ensuring the efficiency and safety of the system. For example, the infusion pump 300 can be a diaphragm pump, a plunger pump, etc., and there are no special limitations.

[0033] See Figure 1 As shown, according to some embodiments of the present invention, the infusion branch tube 220 is provided with a first control valve 221.

[0034] By installing a first control valve 221 on the infusion branch 220, the opening and closing of the corresponding infusion branch 220 can be controlled by the first control valve 221, so as to achieve precise control and distribution of infusion flow.

[0035] Specifically, when some aerators 700 need to be cleaned, the corresponding infusion branch pipe 220 can be opened using the first control valve 221, while the infusion branch pipes 220 corresponding to the remaining aerators 700 that do not require cleaning can be closed. Alternatively, the corresponding first control valves 221 can be opened sequentially to clean each aerator 700 in turn. After the current aerator 700 is cleaned, the next first control valve 221 is automatically opened, opening the next infusion branch pipe 220 to clean the next aerator 700, until all aerators 700 are cleaned.

[0036] The first control valve 221 is a priority electric ball valve, which provides precise on / off control and reliable flow regulation. The electric ball valve, controlled by an electric actuator, enables precise control of the on / off state of the infusion branch 220. Compared to manual valves, electric ball valves offer higher automation and remote control capabilities, allowing for more flexible and convenient operation. Of course, the first control valve 221 can also be an electric regulating valve or other similar valve; there are no specific limitations on this.

[0037] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a pressure relief pipe 400 and a pressure relief valve 410. The pressure relief valve 410 is located on the pressure relief pipe 400. The first end of the pressure relief pipe 400 is connected to the infusion main pipe 210, and the connection position between the pressure relief pipe 400 and the infusion main pipe 210 is located downstream of the infusion pump 300.

[0038] By setting up a pressure relief pipe 400 and a pressure relief valve 410, when the pressure in the infusion main pipe 210 exceeds a set value, the pressure relief valve 410 will open to discharge the cleaning solution to a set location, thereby ensuring the safety and stability of the system. When the pressure in the infusion main pipe 210 is too high, the pressure relief valve 410 can automatically open to release the excess pressure and prevent the solution from leaking.

[0039] Specifically, the pressure relief valve 410 can be selected from back pressure valves, spring-loaded pressure relief valves, diaphragm pressure relief valves, electric pressure relief valves, pneumatic pressure relief valves, and regulating pressure relief valves, etc., depending on the system's working pressure, flow requirements, and automation control needs, without any special restrictions.

[0040] See Figure 1 As shown, according to some embodiments of the present invention, the second end of the pressure relief pipe 400 is connected to the liquid storage device 100.

[0041] By connecting the second end of the pressure relief pipe 400 to the liquid storage device 100, when the pressure in the infusion main pipe 210 exceeds a set value, the pressure relief valve 410 can be opened to discharge the cleaning solution into the liquid storage device 100, allowing the solution to be directly recycled back into the storage device 100 for reuse. Simultaneously, the liquid storage device 100 can store excess solution for use in subsequent cleaning processes.

[0042] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a pressure detection device 211, which is located in the infusion main pipe 210.

[0043] By installing a pressure detection device 211 on the infusion main pipe 210, the pressure change in the infusion main pipe 210 can be monitored in real time. When the pressure exceeds the set value, the pressure detection device 211 can automatically control the pressure relief valve 410 or the pump to adjust, so as to ensure that the system pressure is always within the safe operating range.

[0044] Furthermore, when cleaning a single aerator 700, the pressure value detected by the pressure detection device 211 reflects the scaling condition of the aerator 700. For example, when the aerator 700 has a lot of scaling, the pressure value detected by the pressure detection device 211 is higher, and the amount of cleaning solution delivered can be increased. Conversely, when the aerator 700 has less scaling, the pressure value detected by the pressure detection device 211 is lower, and the amount of cleaning solution delivered can be reduced. During the cleaning process of the aerator 700, the pressure value will gradually decrease. When the pressure value decreases to the set value, a certain volume of cleaning solution is then applied under constant pressure to complete the cleaning of the aerator 700.

[0045] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a flow detection device 212, which is located in the infusion main pipe 210.

[0046] By installing a flow detection device 212 on the infusion tube 210, the flow rate of the medicine solution can be monitored in real time.

[0047] In practice, a PLC (Programmable Logic Controller) can collect data signals from the pressure detection device 211 and the flow detection device 212. Based on these data signals, the system controls the infusion pump 300 and the first control valve 221, automatically adjusting the output flow rate according to the pressure data signal to thoroughly clean the aerator 700. Operators only need to set the relevant parameters, and the system will operate automatically without manual intervention.

[0048] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a second control valve 213, which is located on the infusion main pipe 210 and upstream of the infusion pump 300.

[0049] By setting a second control valve 213 upstream of the infusion pump 300, the opening or closing of the liquid storage device 100 can be controlled. When the aerator 700 needs to be cleaned, the infusion main pipe 210 can be opened through the second control valve 213 so that the medicine in the liquid storage device 100 can flow out smoothly. After the cleaning operation is completed, the infusion main pipe 210 and the liquid outlet device can be closed through the second control valve 213 to prevent the medicine from flowing out.

[0050] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a third control valve 214, which is located downstream of the infusion pump 300.

[0051] By setting a third control valve 214 downstream of the infusion pump 300, the flow rate and pressure of the medicine output by the infusion pump 300 can be controlled by the third control valve 214 to ensure that the amount and pressure of the medicine flowing downstream meet the set requirements.

[0052] Similarly, the second control valve 213 and the third control valve 214 are preferably solenoid valves, which can be remotely controlled by the PLC to realize the automated operation of the system.

[0053] See Figure 1 As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a pulse elimination device 500, which is located in the infusion main pipe 210 and downstream of the infusion pump 300.

[0054] By installing a pulse elimination device 500 downstream of the infusion pump 300, the pressure of the medicine output by the infusion pump 300 can be stabilized, thereby ensuring that the liquid is in a stable pressure state and avoiding instability of liquid flow or pressure fluctuation caused by pulse fluctuation of the infusion pump 300.

[0055] Specifically, in this embodiment, the infusion pump 300 is a diaphragm pump, which generates pulsating pressure (i.e., pressure pulses) during operation. This pulsating pressure affects the flow stability of the liquid. The pulse elimination device 500 is equipped with an energy storage element (such as an air bladder or spring). When the infusion pump 300 generates a pressure pulse, the energy storage element can absorb and store excess energy. When the pressure is low, the energy storage element releases the energy to help maintain the continuous flow of the liquid and ensure stable liquid pressure.

[0056] See Figure 1As shown, according to some embodiments of the present invention, the aerator cleaning system further includes a filter device 600, which is located on the infusion main pipe 210 and upstream of the infusion pump 300.

[0057] By installing a filter device 600 upstream of the infusion pump 300, impurities and particulate matter in the drug solution can be effectively removed, preventing them from entering the infusion pump 300 and downstream pipelines, thereby protecting the infusion pump 300 and preventing impurities from clogging or damaging the equipment.

[0058] Specifically, the filtration device 600 in this embodiment adopts a Y-type filter, which is equipped with filter elements such as stainless steel mesh, and the filtration accuracy can be customized according to requirements. Its structure is simple, easy to disassemble and clean, effectively reducing maintenance workload, and because the flow loss during fluid passage is small, it does not significantly affect system efficiency.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
