Description

Technical Field

[0001] This invention relates to the field of water supply technology, and in particular to a self-stabilizing circulating water supply system that utilizes ozone disinfection. Background Technology

[0002] In domestic drinking water supply, secondary water supply pump sets require pressure tanks as pressure stabilizing devices. These pressure tanks have a rubber diaphragm inside, with gas pre-filled in the space between the diaphragm and the tank wall. The pre-filled gas pressure matches the pump's operating pressure. If leakage occurs, an air compressor replenishes the gas and pressure, achieving a stabilizing effect. However, this technology has limitations: firstly, there is a risk of gas leakage, requiring an air compressor to handle pressure leaks; secondly, the rubber diaphragm of the pressure tank is prone to aging and oxidation, which can lead to damage to system equipment and secondary water pollution. These problems result in insufficient stability and safety of the water supply system. Summary of the Invention

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figure 1 This invention describes a self-regulating pressure circulating water supply system utilizing ozone disinfection according to an embodiment of the present invention. The self-regulating pressure circulating water supply system of the present invention is specifically applicable to domestic drinking water, especially piped direct drinking water supply systems.

[0020] This invention proposes a self-regulating pressure circulating water supply system utilizing ozone disinfection. The self-regulating pressure circulating water supply system includes a water supply pipeline 11, an ozone supply unit, a pressure stabilizing unit, and a return water pipeline 6. The water supply pipeline 11 connects to multiple water-using terminals and is equipped with a water supply pump 3. The ozone supply unit is located in the water supply pipeline 11 and before the water supply pump 3 to facilitate the addition of ozone into the water supply pipeline 11. The ozone is suitable for reacting in the water to generate gas. The pressure stabilizing unit is connected to the water supply pipeline 11 and is located between the water supply pump 3 and the water-using terminals. The pressure stabilizing unit is suitable for collecting and storing the gas in the water. The return water pipeline 6 connects to the multiple water-using terminals to facilitate the return of water to the water supply terminals.

[0021] According to the self-regulating circulating water supply system of the present invention, the water supply pipeline 11, the return water pipeline 6, and the water supply and water consumption ends are configured as a circulating water supply system. The water supply pipeline 11 supplies water from the water supply end to the water consumption end through the water supply pump 3. After water consumption, the water flows back to the water supply end through the return pipeline 6. During the water supply process, the ozone supply unit adds ozone to the water supplied by the water supply pipeline 11. The ozone reacts with substances in the water in an oxidation-reduction reaction to produce oxygen and other products. This not only disinfects the water but also replenishes the water supply with gas. The gas in the water automatically collects and stores in the pressure stabilizing unit without the need for auxiliary equipment. When the water pressure in the system changes, the gas in the pressure stabilizing unit expands or is compressed under the water pressure, thereby maintaining the pressure balance of the system and achieving a pressure stabilizing effect. Specifically, when the system pressure rises, water flows into the pressure stabilizing unit to compress the stored gas. Part of the water's kinetic energy is converted into gas potential energy, making the pressure rise more gradual and preventing the water supply pump 3 from stopping due to sudden excessive pressure. When the system pressure drops, the stored gas expands, pushing the water in the pressure stabilizing unit back into the water supply pipeline 11, making the pressure drop more gradual and preventing the water supply pump 3 from immediately starting due to sudden low pressure. Therefore, the pressure stabilizing unit can smooth pressure changes, preventing the water supply pump 3 from frequently starting and stopping due to small, transient pressure changes, thus achieving a pressure stabilizing effect. Simultaneously, the amount of gas stored in the pressure stabilizing unit can automatically select and match according to different system pressure requirements, improving the adaptability of the system's pressure stabilization effect.

[0022] The self-regulating circulating water supply system of the present invention achieves automatic replenishment and pressure regulation of the stabilizing gas within the water supply system by setting up an ozone supply unit and a pressure stabilizing unit. It requires no maintenance, eliminating the need for a diaphragm in the pressure stabilizing tank to store gas. Furthermore, it eliminates the need for additional measures to address gas leaks, preventing problems such as pressure leakage, diaphragm aging, and ozone-induced diaphragm oxidation, further avoiding system structural damage and secondary water pollution. This invention can improve the safety and stability of the water supply system.

[0023] According to some embodiments of the present invention, the ozone supply unit includes a water jet injector 22, a water jet injector pump 21, and a first control valve 23. The water jet injector 22 is adapted to introduce ozone and mix it with water in a jet stream; the water jet injector pump 21 is adapted to supply water to the water jet injector 22; the first control valve 23 is disposed between the water jet injector pump 21 and the water jet injector 22 to control the water supply flow rate and pressure. In this embodiment, by setting the water jet injector pump 21 and the water jet injector 22, the negative pressure formed by the high-speed water flow can be used to draw in ozone and mix it violently with the water flow, so that the ozone is evenly dispersed in the water in a short time to form an ozone aqueous solution. The mixing efficiency is high, which can ensure that the ozone is in full contact with the water and improve the utilization rate of ozone. The water jet injector 22 can generate a powerful jet, and the mixed ozone aqueous solution is sprayed out in the form of a high-speed jet, which can quickly diffuse into the entire water body of the water supply system. By adjusting the opening of the first control valve 23, the flow rate and pressure of the water entering the water jet injector 22 can be precisely controlled, thereby adjusting the amount of ozone added and the mixing effect, maintaining the stability of the inlet water flow rate and pressure of the water jet injector 22, and thus ensuring the overall stable and reliable performance of the ozone supply unit. The water jet injector 22 is connected to the ozone generator.

[0024] According to some embodiments of the present invention, the self-regulating pressure circulating water supply system further includes an ozone dosing pipeline 12; a check valve 13 is provided on the water supply pipeline 11, and the ozone dosing pipeline 12 and the check valve 13 are connected in parallel; an ozone supply unit is provided on the ozone dosing pipeline 12. In this embodiment, since the water pressure of the water ejector 22 is higher than the normal water pressure of the water supply system, by bypassing the ozone dosing pipeline 12, the pressure of the water ejector 22 can be regulated without affecting the normal water supply of the water supply pipeline 11, thus meeting the operating requirements of the water ejector 22. By providing the check valve 13, the water flow direction can be limited, improving the safety and stability of the system operation. Furthermore, the water supply pump 3 and the pressure stabilizing unit are provided on the water supply pipeline 11 after the ozone supply unit.

[0025] According to some embodiments of the present invention, the pressure stabilizing unit includes a pressure stabilizing tank 41 and a pressure detection device. The pressure stabilizing tank 41 is connected to the water supply pipeline 11 and is disposed on the upper side of the water supply pipeline 11 to facilitate automatic collection and storage of gas in the water. The pressure detection device is suitable for detecting the medium pressure inside the pressure stabilizing tank 41. In this embodiment, gas collection and storage are achieved by setting up the pressure stabilizing tank 41. The pressure stabilizing tank 41 is connected to the upper side of the water supply pipeline 11, allowing for automatic gas collection based on gas density. During water supply, the gas generated by the ozone reaction is automatically collected and stored in the pressure stabilizing tank 41. When the system water pressure changes, the stored gas undergoes compression and expansion under the water pressure, achieving a pressure stabilizing effect. By setting up the pressure detection device, the internal pressure of the pressure stabilizing tank 41 can be detected in real time to monitor the pressure fluctuations of the water supply system and control the start and stop of the water supply pump 3 accordingly. This embodiment uses the pressure stabilizing tank 41 and the pressure detection device as structural components for gas collection, storage, and pressure detection, ensuring the safe and stable operation of the water supply system. The structure is simple and easy to install and maintain.

[0026] In some embodiments, such as Figure 1 As shown, the pressure detection element is constructed as a pressure gauge 42 and is installed on the top of the pressure stabilizing tank 41 to detect the air pressure inside the pressure stabilizing tank 41.

[0027] According to some embodiments of the present invention, the pressure stabilizing unit further includes a second control valve 43, which is disposed between the pressure stabilizing tank 41 and the water supply pipeline 11. In this embodiment, by adjusting the opening degree of the second control valve 43, the amount of gas entering and exiting the pressure stabilizing tank 41 can be controlled, and the flow rate of water entering and exiting the pressure stabilizing tank 41 can be controlled when the system pressure changes, thereby controlling the buffer time when the system pressure changes, avoiding frequent start and stop of the water supply pump 3, achieving a pressure stabilizing effect, and further improving the safety and reliability of the system. In some embodiments, the pressure stabilizing tank 41 is connected to the water supply pipeline 11 through a pressure stabilizing pipeline, and the second control valve 43 is disposed in the pressure stabilizing pipeline.

[0028] According to some embodiments of the present invention, a pressure-stabilizing cavity is formed inside the pressure-stabilizing tank 41. The pressure-stabilizing cavity is constructed as a single continuous cavity defined by the inner wall of the pressure-stabilizing tank 41; the pressure-stabilizing cavity is suitable for containing gas and water. In this embodiment, the pressure-stabilizing tank 41 forms a single continuous cavity as a pressure-stabilizing cavity for containing gas and water, that is, no pressure-controlling structural components such as diaphragms are provided inside the pressure-stabilizing tank 41. This simplifies the structure, extends the service life of the pressure-stabilizing tank 41, effectively avoids problems such as damage, aging, and oxidation of diaphragms and other structures, avoids pollution of water, and can achieve a reliable pressure-stabilizing effect for a long time.

[0029] According to some embodiments of the present invention, the pressure stabilizing tank 41 is cylindrical, with a diameter D and a height H, satisfying 100mm ≤ D ≤ 400mm and 100mm ≤ H ≤ 800mm. The pressure stabilizing capacity of the pressure stabilizing tank 41 depends on the volume (i.e., capacity) of the compressible gas inside; the larger the volume, the more water is absorbed and released, and the better the buffering effect. This embodiment provides a capacity range for the pressure stabilizing tank 41 that can achieve effective pressure stabilization. In practice, the capacity of the pressure stabilizing tank 41 can be determined by flexibly selecting the height and diameter to match the pressure stabilization requirements of the system while adapting to installation space limitations.

[0030] According to some embodiments of the present invention, the flow rate of the water jet injector 22 is Q, and satisfies 0.1t / h ≤ Q ≤ 1t / h. In this embodiment, the flow rate of the water jet injector 22 is controlled within the above range, allowing ozone addition to be implemented according to the system's pressure stabilization requirements, ensuring a sufficient supply of pressure-stabilizing gas, and guaranteeing the disinfection effect of the water. Simultaneously, in conjunction with the first control valve 23, the water jet injector 22 can flexibly adjust its operating state, controlling the flow rate within the above range, adapting to various operating conditions without frequent equipment replacement or setting adjustments.

[0031] According to some embodiments of the present invention, the distance between the water supply pump 3 and the water-using end located at the most unfavorable point is L, and L ≤ 800m. In this embodiment, the most unfavorable water-using end refers to the water-using end farthest from the water supply pump 3. Based on water quality testing requirements, after testing, when the distance between the water supply pump 3 and the water-using end located at the most unfavorable point is no greater than 800m, the required ozone content can be detected in the water supplied at the water-using end located at the most unfavorable point. This embodiment limits the distance between the water supply pump 3 and the most unfavorable water-using end, ensuring the safe and stable operation of the water supply system and meeting water supply requirements. Figure 1 As shown, the water-using end generally refers to the water tap 5.

[0032] According to some embodiments of the present invention, the self-regulating pressure circulating water supply system further includes an exhaust unit, which is disposed at a high point in the water supply pipeline 11 to facilitate the discharge of gas from the water. In this embodiment, by providing an exhaust unit, gas can be released from the water supply system to discharge gas from the water, preventing gas from accumulating in the water supply pipeline 11 and affecting the normal operation of the system. Specifically, the exhaust unit is constructed as an exhaust valve 7, disposed at a high point in the water supply pipeline 11, so as to utilize the low gas density to achieve gas discharge.

[0033] In addition, the water supply pipeline 11 and the return water pipeline 6 are combined to form a circulating pipeline. Both the water supply pipeline 11 and the return water pipeline 6 are equipped with a third control valve 14 to control the flow rate and pressure of the system water supply and return water.

[0034] This invention can effectively improve the stability and safety of water supply, optimize the structure of the water supply system, simplify operation, and has high applicability. It can be applied to domestic drinking water systems, especially piped direct drinking water systems.
