Description

Technical Field

[0001] This invention relates to the field of water tank cleaning, and more specifically, to a water supply tank cleaning system and cleaning method. Background Technology

[0002] With the rapid advancement of urbanization, water supply systems, as a crucial component of urban infrastructure, bear the vital mission of providing residents with safe and reliable water sources. However, water tanks, as a key node in the water supply system, are directly affected by the cleanliness of their internal environment, which in turn impacts the quality and safety of the water supply. Because water tanks are typically enclosed, they are susceptible to external environmental influences, leading to water pollution and bacterial growth. Therefore, regular cleaning and disinfection of water tanks is a critical step in ensuring water supply safety.

[0003] Traditional water tank cleaning methods typically have several problems:

[0004] 1. First, traditional cleaning methods are mostly manual, requiring people to enter the water tank to scrub and disinfect. This is not only cumbersome and inefficient, but also poses significant safety hazards, such as occupational health and safety risks like collisions, scratches, and suffocation.

[0005] 2. Traditional cleaning methods use a lot of fresh water to rinse, and in order to get it clean, they often need to be washed for a long time and many times, which will result in a great waste of water resources.

[0006] 3. The water from the water supply tank usually needs to undergo water quality testing. However, after the water supply tank is cleaned, most of the inner surface is cleaned. However, there are still stubborn dirt and impurities in some areas of the inner surface. The remaining dirt and impurities may still cause the water quality to fail to meet the standards. Therefore, it is necessary to repeatedly flush the large area, which wastes a lot of water resources.

[0007] To address the aforementioned issues, improve water tank cleaning efficiency, and conserve water resources, the development of an electrochemical water-saving cleaning system and method for water supply tanks is of paramount importance. The development of such a system and method has significant practical application value and broad market prospects. It not only helps improve the safety and stability of water supply systems and ensure the quality and safety of residential water use, but also promotes innovation and development in clean technologies, and facilitates the sustainable use and protection of water resources. Summary of the Invention

[0008] The main purpose of this application is to provide a water tank cleaning system and cleaning method, so as to at least improve the problem that the water tank cleaning method in the prior art causes a great waste of water resources.

[0009] To achieve the above objectives, this application adopts the following technical solution:

[0010] On the one hand, a water supply tank cleaning system is provided, including: a water tank, an electrochemical cleaning component, a circulating water component, and a flow control component. The system includes a water tank with a drain outlet; an electrochemical cleaning assembly with an anode and a cathode mounted on the inner wall of the water tank and connected to a transformer power supply; a circulating water assembly with a top guide component, a circulating water pump, a conductivity sensor, and an electrolyte replenishment device. The top guide component allows cleaning water to flow evenly down the inner wall of the water tank from the top. The circulating water pump is connected to the top guide component and detachably installed at the drain outlet. The circulating water pump circulates the cleaning water to the top guide component and controls the initial flow rate of the cleaning water. The electrolyte replenishment device replenishes electrolytes to the cleaning water at a preset concentration. The conductivity sensor monitors the electrolyte concentration in the cleaning water in real time. A flow control assembly with a flow velocity sensor and a perforated guide plate mounted on the inner wall of the water tank reduces the flow velocity of the cleaning water flowing along the inner wall of the water tank. The flow velocity sensor is installed at multiple preset positions inside the water tank to monitor the flow velocity of the cleaning water flowing along the inner wall of the water tank in real time.

[0011] By adopting the above technical solution, the cleaning system can effectively remove dirt and deposits in the water tank through electrochemical reaction. At the same time, the circulating water component and flow control component ensure the uniform distribution and flow rate control of the cleaning water, thereby saving water for tank cleaning, improving cleaning efficiency and cleaning effect.

[0012] Furthermore, the anode and cathode of the electrochemical cleaning assembly are made of conductive and corrosion-resistant materials.

[0013] By adopting the above technical solution, both the anode and cathode are made of corrosion-resistant and conductive materials, which ensures the high efficiency of the electrochemical reaction and the long-term stability of the system, and reduces the risk of electrode corrosion and damage.

[0014] Furthermore, there are multiple anodes and cathodes. Multiple anodes are arranged on the upper part of the inner wall of the water tank and are evenly spaced along the circumference of the inner wall of the water tank. Multiple cathodes are arranged on the lower part of the inner wall of the water tank and are evenly spaced along the circumference of the inner wall of the water tank. Multiple anodes are connected in parallel and connected to the positive terminal of the transformer power supply. Multiple cathodes are connected in parallel and connected to the negative terminal of the transformer power supply.

[0015] By adopting the above technical solution, the uniform distribution and parallel connection of multiple anodes and cathodes ensures the uniform distribution of current, improves cleaning efficiency and effect, and extends the service life of the electrodes.

[0016] Furthermore, the circulating water assembly also includes a filter device, which is located between the circulating water pump and the drain outlet, and is used to filter solid dirt from the water.

[0017] By adopting the above technical solution, the filtration device in the circulating water component can effectively remove solid dirt from the cleaning water, ensuring the cleanliness of the cleaning water, thereby improving the electrochemical cleaning effect and the overall operating efficiency of the system.

[0018] Furthermore, the perforated guide plate is multi-layered, with the multi-layered perforated guide plate evenly spaced along the height direction of the water tank, and each layer of perforated guide plate horizontally surrounding the circumference of the water tank.

[0019] By adopting the above technical solution, the multi-layer porous guide plates are evenly spaced along the height of the water tank, which can effectively reduce the flow velocity of the cleaning water along the inner wall of the water tank, ensure the uniform coverage of the cleaning water on the inner wall of the water tank, and improve the cleaning effect.

[0020] Furthermore, the porous guide plate includes a porous surface and a guide surface. The porous surface is used to slow down the cleaning water flowing down the inner wall of the water tank, and the guide surface is used to allow the slowed cleaning water to continue flowing down the inner wall of the water tank. Multiple guide holes are opened on the porous surface.

[0021] By adopting the above technical solution, the porous surface and guide surface design of the porous guide plate can slow down and guide the cleaning water to flow along the inner wall of the water tank, ensuring the uniform distribution of the cleaning water and further improving the cleaning effect.

[0022] Furthermore, there are multiple flow rate sensors, which are evenly arranged above each layer of porous guide plate.

[0023] By adopting the above technical solution, flow rate sensors are evenly distributed above each layer of porous guide plates, which can monitor the flow rate of cleaning water in real time and adjust the initial velocity through a circulating water pump to ensure that the flow rate is within the optimal range, thereby improving cleaning efficiency and effect.

[0024] On the other hand, a method for cleaning a water supply tank is provided, which is applied to the aforementioned water supply tank cleaning system, including:

[0025] The water tank is reserved for 1 / 4 to 1 / 3 of the total volume of cleaning water, and the initial electrolyte dosage is calculated according to the volume and preset concentration of the cleaning water.

[0026] Start the circulating water pump to make the cleaning water circulate to the top guide component, and make the cleaning water flow evenly down the inner wall of the water tank from the top of the water tank through the top guide component;

[0027] Electrolytes are replenished in the cleaning water according to the initial electrolyte dosage using an electrolyte replenishment device;

[0028] The conductivity sensor monitors the electrolyte concentration of the cleaning water in the tank and, when the preset concentration is reached, sets the transformer power supply to the preset voltage and turns on the transformer power supply to start the electrochemical cleaning component.

[0029] The initial flow rate is controlled by a circulating water pump, and the flow rate of the cleaning water flowing along the inner wall of the water tank is monitored in real time by a flow rate sensor. A perforated guide plate ensures that the cleaning water is within the preset flow rate range.

[0030] During the electrochemical cleaning process, the water on the inner wall of the tank is electrolyzed, generating microbubbles that peel off dirt from the inner wall of the tank.

[0031] The electrolyte concentration in the cleaning water is monitored in real time by a conductivity sensor, and the electrolyte is replenished to the preset concentration range in a timely manner by an electrolyte replenishment device.

[0032] After cleaning is complete, turn off the transformer power supply, disconnect the lower interface of the circulating water component from the drain port, let the cleaning water flow out, and then reinstall the lower interface of the circulating water component to the drain port.

[0033] Add an appropriate amount of clean water to the water tank and turn on the circulating water system for a period of time to flush the inside of the water tank and the circulating water system.

[0034] Remove the lower connector of the circulating water component and discharge the remaining sewage through the drain outlet.

[0035] This application, by adopting the above technical solution, has at least one of the following beneficial effects:

[0036] 1. This application utilizes an electrochemical cleaning component to effectively remove dirt and deposits from the water tank through an electrochemical reaction. At the same time, it ensures uniform distribution and flow rate control of the cleaning water through a circulating water component and a flow control component, thereby significantly improving cleaning efficiency and effectiveness while reducing water and energy consumption, achieving the goal of energy saving.

[0037] 2. The design of the top guide component, porous guide plate, and flow rate sensor ensures that the cleaning water flows evenly along the inner wall of the tank in a moderately turbulent state, providing a comprehensive and uniform cleaning effect. This design avoids cleaning dead zones, allowing every part of the inner wall of the tank to be thoroughly cleaned. The moderate turbulence effectively mixes the electrolyte solution, ensuring a uniform distribution of electrolyte concentration throughout the tank, thereby improving the efficiency of the electrochemical reaction. Furthermore, the increased mass transfer rate between the electrolyte and the electrode surface under turbulent conditions helps to quickly remove reaction products from the electrode surface, maintaining a high electrochemical reaction rate. The strong fluid movement generated by turbulence can physically peel off dirt and biofilm adhering to the inner wall of the tank, and combined with the electrochemical reaction, can more thoroughly remove dirt. The disturbance of the water flow under turbulence prevents the dirt and deposits peeled off during the cleaning process from re-adhering to the inner wall of the tank. Simultaneously, it avoids problems such as difficulty in bubble removal and mass transfer caused by excessively high flow rates.

[0038] 3. The anode and cathode are made of corrosion-resistant materials, extending the service life of the equipment and reducing maintenance costs caused by corrosion. The filtration device in the circulating water assembly effectively filters solid dirt from the water, preventing it from re-adhering to the inner wall of the water tank during the cleaning process, further improving the cleaning effect and the reliability of the system.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] like Figures 1 to 3As shown in the figure, this application discloses a water tank cleaning system, including: a water tank 1, an electrochemical cleaning component 2, a circulating water component 3, and a flow control component 4. The water tank includes a drain outlet 11; the electrochemical cleaning component includes an anode 21 and a cathode 22, which are disposed on the inner wall of the water tank 1 and connected to a transformer power supply 23; the circulating water component 3 includes a top guide component 31, a circulating water pump 34, a conductivity sensor 32, and an electrolyte replenishment device 33. The top guide component 31 is used to ensure that cleaning water flows evenly down the inner wall of the water tank from the top; the circulating water pump 34 is connected to the top guide component 31 and detachably installed at the drain outlet 11, and the circulating water pump 34 is used for... The cleaning water is circulated to the top guide component 31 and the initial flow rate of the cleaning water is controlled. The electrolyte replenishment device 33 is used to replenish electrolytes in the cleaning water at a preset concentration. The conductivity sensor 32 is used to monitor the electrolyte concentration in the cleaning water in real time. The flow control component 4 includes a flow velocity sensor 42 and a porous guide plate 41. The porous guide plate 41 is set on the inner wall of the water tank 1 to reduce the flow velocity of the cleaning water flowing along the inner wall of the water tank 1. The flow velocity sensor 42 is installed in multiple preset positions inside the water tank to monitor the flow velocity of the cleaning water flowing along the inner wall of the water tank 1 in real time.

[0047] In specific implementation, the anode 21 is made of titanium or ruthenium-plated titanium; the cathode 22 is made of graphite or stainless steel. Both the anode 21 and cathode 22 are made of materials with excellent corrosion resistance and conductivity, ensuring the efficient electrochemical reaction and the long-term stability of the system, and reducing the risk of electrode corrosion and damage. The electrolyte solutes supplemented by the electrolyte replenishment device 33 are sodium carbonate and sodium phosphate, which are prepared in a 10:1 ratio, with a total concentration ranging from 0.05M to 0.5M. Considering cost and the low level of water tank contamination, the initial total concentration of sodium carbonate and sodium phosphate is determined to be 0.05M, which means that 4.77g of sodium carbonate and 0.82g of sodium phosphate are added per liter of water. The electrochemical reaction is as follows:

[0048] Anode: 2H₂O(l) → O₂(g) + 4H₂O + (aq)+

[0049] Cathode: 4H₂O(l) + 4e - →2H2(g)+4OH - (

[0050] This cleaning system effectively removes dirt and deposits from water tank 1 using electrochemical reactions. Simultaneously, the circulating water component 3 and flow control component 4 ensure uniform distribution and flow rate control of the cleaning water, thereby saving water, improving cleaning efficiency, and enhancing cleaning effectiveness. The ozone and hydroxyl radicals generated during electrolysis have strong oxidizing properties, effectively decomposing organic matter and bacteria on the inner wall of water tank 1, thus providing a certain degree of disinfection. Furthermore, when the contamination level of water tank 1 is low, sodium phosphate can be replaced with sodium carbonate at an equimolar concentration for cost reasons. In other embodiments, it is feasible to use other electrolytes or electrode materials. For example, the electrolyte can be replaced with NaCl, a common and lower-cost substance. When NaCl is used as the electrolyte, chlorine gas is produced at the anode 21 instead of oxygen, providing both cleaning and disinfection effects. However, chlorine gas is toxic and has an irritating odor, potentially harming human health and the environment; therefore, ventilation and safety precautions are necessary during operation. Obviously, ventilation is also required during the electrochemical reaction process in this embodiment.

[0051] Meanwhile, considering that sodium carbonate and sodium phosphate have low solubility at low temperatures, which may lead to incomplete dissolution, the dissolution temperature can be appropriately increased. A heating device can be used to heat the water to around 20°C. Combined with appropriate turbulence and the heat generated during electrolysis, this can effectively improve solubility.

[0052] Furthermore, such as Figure 1 As shown, there are multiple anodes 21 and cathodes 22. Multiple anodes 21 are disposed on the upper part of the inner wall of the water tank 1 and evenly spaced along the circumference of the inner wall. Multiple cathodes 22 are disposed on the lower part of the inner wall of the water tank 1 and evenly spaced along the circumference of the inner wall. The multiple anodes 21 are connected in parallel to the positive terminal of the transformer power supply 23. The multiple cathodes 22 are connected in parallel to the negative terminal of the transformer power supply 23. The multiple anodes 21 and cathodes 22 are all thin sheets fixed to the inner wall of the water tank 1, with one anode every meter along the horizontal direction of the inner wall. The uniform distribution and parallel connection of the multiple anodes 21 and cathodes 22 ensure uniform current distribution, improve cleaning efficiency and effect, and extend the service life of the electrodes. Preferably, the voltage range of the transformer power supply 23 is 1.5V to 12V, specifically determined according to the size of the water tank 1 and the degree of contamination; in this embodiment, 3V is selected.

[0053] Furthermore, such as Figure 1 As shown, the circulating water assembly 3 also includes a filter device 35, which is located between the circulating water pump 34 and the drain outlet 11. The filter device 35 is used to filter solid dirt from the water. The filter device 35 in the circulating water assembly 3 can effectively remove solid dirt from the cleaning water, ensuring the cleanliness of the cleaning water, thereby improving the electrochemical cleaning effect and the overall operating efficiency of the system.

[0054] Furthermore, such as Figure 1 and Figure 3 As shown, the porous guide plate 41 is multi-layered, with each layer of porous guide plate 41 evenly spaced along the height direction of the water tank 1. Each layer of porous guide plate 41 is horizontally arranged around the circumference of the water tank 1. In this embodiment, the porous guide plate 41 is spaced 0.5m apart along the height direction of the water tank 1, which effectively reduces the flow velocity of the cleaning water along the inner wall of the water tank 1, ensuring uniform coverage of the cleaning water on the inner wall of the water tank 1 and improving the cleaning effect. Obviously, in other embodiments, the spacing between each layer of porous guide plate 41 can be adjusted according to the flow velocity. The porous guide plate 41 includes a porous surface 411 and a guide surface 412. The porous surface 411 is used to slow down the cleaning water flowing down the inner wall of the water tank 1, and the guide surface 412 is used to allow the slowed cleaning water to continue flowing down the inner wall of the water tank 1. Multiple guide holes are opened on the porous surface 411. The porous guide plate 41 is made of a corrosion-resistant material, such as stainless steel or plastic, with a hole diameter of 8 mm and a hole spacing of 2 cm. The porous surface 411 and the guide surface 412 on the porous guide plate 41 are designed to slow down and guide the cleaning water to flow along the inner wall of the water tank 1, ensuring the uniform distribution of the cleaning water and further improving the cleaning effect.

[0055] Furthermore, such as Figure 1 As shown, there are multiple flow rate sensors 42, which are evenly arranged above each layer of porous guide plate 41. With one flow rate sensor above each layer of porous guide plate 41, the flow rate sensor 42 can monitor the flow rate of the cleaning water in real time and adjust the initial velocity through the circulating water pump 34 to ensure the flow rate is within the optimal range, thereby improving cleaning efficiency and effectiveness.

[0056] like Figure 1 As shown, in this embodiment, the top guide component 31 is a PVC plate that is horizontally fixed to the upper pipe joint of the circulating water component 3. The four corners of the PVC plate are fixed to the top of the water tank 1. Clean water can flow from the multiple openings at the connection between the upper pipe and the PVC plate onto the plate, and then flow through the inclined surface of the plate edge to the inner wall surface of the water tank 1.

[0057] Through the design of the circulating water pump 34, the top guide component 31, the multi-layer porous guide plate 41, and the flow rate sensor 42, the cleaning water forms a continuous and moderately turbulent flow state along the inner wall of the water tank 1, with a flow rate range of 0.1 to 0.5 m / s. The continuity of the water flow ensures the continuity of electrolysis, and the moderately turbulent state has at least one of the following beneficial effects:

[0058] 1. Enhanced mass transfer and improved electrolyte uniformity: Moderate turbulence effectively mixes the electrolyte solution, ensuring a uniform electrolyte concentration throughout the tank, thereby improving the efficiency of the electrochemical reaction. 2. Promoted exchange of reactants and products: Under turbulent conditions, the mass transfer rate between the electrolyte and the electrode surface increases, facilitating the rapid removal of reaction products from the electrode surface and maintaining a high electrochemical reaction rate.

[0059] 2. Improve cleaning efficiency and enhance physical stripping effect. The strong fluid movement generated by turbulence can physically strip away dirt and biofilm adhering to the inner wall of water tank 1. Combined with electrochemical reaction, it can remove dirt more thoroughly. Reduce re-adhesion of deposits. Under turbulent conditions, the disturbance of water flow can prevent dirt and deposits stripped during the cleaning process from re-adhering to the inner wall of water tank 1.

[0060] 3. Turbulent current can evenly distribute the current density, avoiding electrode corrosion or excessive reaction caused by excessive local current, thereby extending the service life of the electrodes and improving the overall stability of the system.

[0061] 4. Preventing local overheating: In turbulent flow, heat transfer in the solution is accelerated, which helps maintain a uniform temperature of the electrolyte solution, prevents local overheating, and improves system safety and efficiency.

[0062] Meanwhile, to avoid reducing reaction efficiency, the flow rate cannot be too high, as excessive flow rate can lead to difficulties in bubble removal and limited mass transfer. Difficult bubble removal means that at high flow rates, bubbles (such as hydrogen and oxygen) generated on the electrode surface may be removed more quickly by the water flow, thus weakening the mechanical removal effect of the bubbles on the fouling. Limited mass transfer means that although moderate turbulence helps improve mass transfer, excessively high flow rates may result in an excessively thin mass transfer layer, affecting the transfer of reactants to the electrode surface and thus reducing the efficiency of the electrochemical reaction.

[0063] On the other hand, a water supply tank cleaning method is provided, which is applied to the above-mentioned water supply tank 1 cleaning system, including: reserving 1 / 4 to 1 / 3 of the total volume of cleaning water in the water tank 1, and calculating the initial electrolyte dosage according to the volume and preset concentration of the cleaning water; starting the circulating water pump 34 to make the cleaning water circulate to the top guide component 31, and making the cleaning water flow evenly down the inner wall of the water tank 1 from the top of the water tank 1 through the top guide component 31; adding electrolyte to the cleaning water according to the initial electrolyte dosage through the electrolyte replenishment device 33; the conductivity sensor 32 monitors the electrolyte concentration of the cleaning water in the water tank 1, and when the preset concentration is reached, sets the transformer power supply 23 to the preset voltage and turns on the transformer power supply 23 to power the electrochemical cleaning component 2. Start-up; the initial flow rate is controlled by the circulating water pump 34, and the flow rate of the cleaning water flowing along the inner wall of the water tank 1 is monitored in real time by the flow rate sensor 42. The porous guide plate 41 ensures that the cleaning water is within the preset flow rate range; the water on the inner wall of the water tank 1 is electrolyzed, generating microbubbles that peel off dirt from the inner wall of the water tank 1. During electrolysis, water molecules are decomposed into hydrogen and oxygen, and a large number of microbubbles are formed on the electrode surface. These microbubbles not only contain gas molecules, but also carry active substances generated by electrolysis (such as hydroxide ions, hydrogen peroxide, etc.). These active substances have a stronger ability to peel off dirt. On the one hand, the gases generated by electrolysis (mainly hydrogen and oxygen) form microbubbles on the electrode surface. These microbubbles will rise and... The microbubbles physically impact the dirt on the inner wall of the water tank. Their bursting effect and the flowing water break down the adhesion between the dirt and the tank wall, causing it to gradually loosen and peel off. Furthermore, hydroxide ions, being highly alkaline, can neutralize acidic substances or metal ions in the dirt, altering its chemical properties and making it easier to remove. Additionally, hydroxide ions possess oxidizing properties, capable of oxidizing or dissolving organic components in the dirt. Hydrogen peroxide, a strong oxidant, can react with various components in the dirt. Although the amount of hydrogen peroxide generated during electrolysis is relatively small, its strong oxidizing properties effectively decompose organic components in the dirt, such as oil. The electrolysis process transforms lipids, proteins, and other substances into soluble compounds, making them easier to remove. Changes in chemical properties (such as neutralization and oxidation) alter the chemical structure of the dirt, making it easier to peel off. Furthermore, the heat and energy changes generated during electrolysis may also aid in the removal of dirt. In summary, the active substances produced by electrolysis effectively remove dirt from the inner wall of the water tank through a combination of physical impact and chemical action. This cleaning method is not only environmentally friendly and efficient but also reduces damage to the water tank material and the risk of secondary pollution. The electrolyte concentration in the cleaning water is monitored in real time by a conductivity sensor 32, and the electrolyte replenishment device 33 replenishes the electrolyte to the preset concentration range in a timely manner.After cleaning, turn off the transformer power supply 23, disconnect the lower interface of the circulating water component 3 from the drain port 11, allowing the cleaning water to flow out, and then reconnect the lower interface of the circulating water component 3 to the drain port 11; add an appropriate amount of clean water to the water tank 1, and turn on the circulating water component 3 for a period of time to rinse the inside of the water tank 1 and the circulating water component 3; remove the lower connector of the circulating water component 3, and drain the remaining wastewater from the drain port 11. The cleaning method effectively utilizes electrochemical reactions through the electrochemical cleaning component to remove dirt and deposits from the water tank. Simultaneously, the circulating water component and flow control component ensure uniform distribution and flow rate control of the cleaning water, thereby significantly improving cleaning efficiency and effectiveness while reducing water and energy consumption, achieving the goal of energy and water conservation.

[0064] When applying this embodiment, the following precautions should be taken: real-time monitoring of electrolyte concentration to ensure it remains within the effective range to guarantee the efficiency of the electrochemical reaction; system cleanliness, including regular cleaning of the filter device 35 and the circulating water assembly 3 to prevent clogging and efficiency degradation; safe operation, ensuring good ventilation during system operation to avoid the accumulation of hydrogen and oxygen and ensure safety; regular inspection of connection points to ensure wires and connectors remain secure and prevent loosening or oxidation leading to poor contact; and waterproofing, with all electrical connection points waterproofed to prevent water ingress that could cause short circuits or electrolyte leakage.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
