[0002] In places such as homes, outdoor pools, and small water treatment rooms, small-scale water treatment equipment is commonly used for disinfection and sterilization of the water. This type of equipment often uses ozone as a disinfectant. During disinfection, ozone needs to be injected into the water to be treated. However, this method has the following problems:
[0003] 1. Ozone has low solubility in water, and its solubility varies with water temperature. This results in low mixing efficiency between ozone and water, leading to low utilization of ozone.
[0004] 2. When undissolved ozone is discharged directly into external water bodies (such as pools and ponds), it will disrupt the chemical balance of the water, causing the ozone concentration in the water to rise rapidly. This may form harmful byproducts such as bromate and increase the risk to human health.
[0005] For water treatment equipment that uses ozone for disinfection, how to improve the utilization rate of ozone and how to recover ozone to prevent ozone leakage are urgent problems to be solved. Summary of the Invention

[0044] Example
[0045] See Figures 1-3 In this embodiment, a water treatment device with an ozone circulation loop is proposed, including an inlet pipe 100, a water tank 200 and a water delivery pipe 300.
[0046] The water supply pipeline 300 is used to transport water from the inlet pipeline 100 to the water tank 200, wherein the inlet of the water tank 200 is connected to the outlet of the water supply pipeline 300. In the figure, arrow a indicates the inlet of the water tank 200, and arrow b indicates the outlet of the water tank 200.
[0047] like Figure 4 As shown, the water inlet pipe 100 includes an inlet 110, a first interface 120, and a second interface 130. Figure 5 As shown, a third interface 310 is provided on the water supply pipeline 300, where arrow c indicates the water inlet of the water supply pipeline 300 and arrow d indicates the water outlet of the water supply pipeline 300.
[0048] The inlet 110 is used to supply the water to be treated; the first port 120 is connected to the inlet of the water supply pipeline 300 through the gas-liquid mixer 400; the second port 130 is connected to the third port 310 through the vertically arranged recovery pipeline 500. Specifically, when the water treatment equipment is in operation, both the water tank 200 and the recovery pipeline 500 are in a vertical position.
[0049] The recovery pipeline 500 is used to transport undissolved ozone from the water supply pipeline 300 back to the water inlet pipeline 100 for recycling.
[0050] The gas-liquid mixer 400 is used to mix water and ozone. The gas-liquid mixer 400 is equipped with an ozone input pipe 600, which is used to deliver ozone to the gas-liquid mixer 400.
[0051] When the water treatment equipment is operating, the water to be treated flows into the inlet pipe through the inlet 110 and into the gas-liquid mixer 400 through the first interface 120; ozone enters the gas-liquid mixer 400 through the ozone input pipe 600; in the gas-liquid mixer 400, the ozone mixes with the water, and some of the ozone dissolves in the water; after exiting the gas-liquid mixer 400, the fluid (including ozone and water) enters the water supply pipe 300 through the inlet section of the water supply pipe 300. In the process described above, when the fluid flows through the third port 310 of the water supply pipeline 300, some ozone that is not dissolved in the water will flow into the second port 130 along the vertically set recovery pipeline 500 and return to the water inlet pipeline 100. As water is continuously input into the water inlet 110, the ozone that returns to the water inlet pipeline 100 through the recovery pipeline 500 can dissolve in the newly entering water inlet 110. This allows for efficient utilization of ozone and reduces the possibility of ozone leakage, thereby improving safety.
[0052] like Figures 1-3 As shown, an ozone recovery pipe 210 is installed on the top of the water tank 200. The ozone recovery pipe 210 is used to recover ozone from the inner cavity of the water tank 200. The inlet end of the ozone recovery pipe 210 is connected to the inner cavity of the water tank 200, and the outlet end is connected to the ozone input pipe 600. Figure 3 As shown, the top of the inner cavity of the water tank 200 always maintains an air chamber 220 for containing gas.
[0053] A branch pipe 610 is provided on the side of the ozone input pipe 600, wherein the exhaust end of the ozone recovery pipe 210 is connected to the ozone input pipe 600 through the branch pipe 610.
[0054] Before the water treatment equipment operates, a certain amount of pre-treated water (such as purified water) can be pre-filled into the water tank 200. The water tank 200 should be placed vertically, and the water level should be at least level with the top of the drain outlet of the water tank 200 (i.e., the water level needs to cover the drain outlet of the water tank 200) to prevent undissolved ozone in the water tank 200 from being discharged through the drain outlet. Furthermore, the water in the water tank 200 should never completely fill its inner cavity (including during operation) to ensure that the gas chamber 220 is always present, thereby containing any undissolved ozone in the water tank 200. Figure 3 In the middle, the dotted and dashed lines inside water tank 200 indicate the water level line inside water tank 200.
[0055] When the water treatment equipment is running, as the water flows through the water supply pipe 300, some undissolved ozone will be transported back to the inlet pipe 100 through the recovery pipe 500. However, some undissolved ozone may still flow into the water tank 200 with the water. After the water and undissolved ozone enter the water tank 200, the undissolved ozone will gradually accumulate in the gas chamber 220 at the top of the inner cavity of the water tank 200. Subsequently, this part of the ozone will flow back to the ozone input pipe 600 through the ozone recovery pipe 210, and then flow back to the gas-liquid mixer 400 along with the ozone that was previously input into the ozone input pipe 600. This achieves the recovery and utilization of undissolved ozone and further reduces the possibility of ozone leakage.
[0056] Therefore, it can be seen that the water treatment equipment proposed in this application has a dual-loop ozone circulation system:
[0057] First circulation loop: gas-liquid mixer 400 - water supply pipeline 300 - recovery pipeline 500 - water inlet pipeline 100 - gas-liquid mixer 400;
[0058] Second circulation loop: gas-liquid mixer 400 - water supply pipeline 300 - water tank 200 - ozone recovery pipe 210 - ozone input pipe 600 - gas-liquid mixer 400.
[0059] The aforementioned dual-loop system enables the recovery and utilization of undissolved ozone, and greatly reduces the possibility of ozone leakage.
[0060] In this embodiment, the gas-liquid mixer 400 includes a Venturi jet.
[0061] Reference Figure 6 and Figure 7 The Venturi jet ejector works as follows: When fluid enters the converging section 410 of the ejector, the cross-sectional area of the pipe gradually decreases, increasing the fluid velocity and causing a decrease in static pressure, thus forming a low-pressure zone at the throat 420 (the narrowest point). Subsequently, the fluid enters the diffuser section 430, where the cross-sectional area of the pipe gradually increases, slowing the fluid velocity and causing the pressure to rise but still remain lower than the fluid pressure at the inlet of the Venturi jet ejector. Therefore, the inlet pressure is typically higher, and the outlet pressure is lower; this pressure difference is crucial for driving the mixing and transport of the fluid (ozone and water in this application). For example, Figure 7 As shown, an air inlet pipe is provided on the right side of the gas-liquid mixer 400, which is connected to the ozone input pipe 600.
[0062] Furthermore, because the inlet pressure of a Venturi jet is typically higher than its outlet pressure during operation, it ensures that the water and ozone do not flow back (i.e., the water and ozone do not flow from the outlet to the inlet of the Venturi jet).
[0063] like Figure 8As shown, the recovery pipeline 500 includes a first connecting pipe 510, a second connecting pipe 520, and a one-way valve 530.
[0064] One end of the first connecting pipe 510 is connected to the second interface 130, and the other end is connected to the outlet of the one-way valve 530.
[0065] One end of the second connecting pipe 520 is connected to the third interface 310, and the other end is connected to the inlet of the one-way valve 530.
[0066] In this embodiment, the one-way valve 530 includes a double-rule check valve. The two ends of the one-way valve 530 can be detachably connected to the first connecting pipe 510 and the second connecting pipe 520 respectively via threaded connections or other means.
[0067] When the water treatment equipment is running, the water to be treated is delivered to the inlet 110 of the inlet pipe 100 by a water pump. Under the control of the water pump, the water pressure in the pipeline (inlet pipe 100 and water delivery pipe 300) is maintained at a first pressure (the first pressure is a range value and can be monitored by a water pressure sensor, etc.).
[0068] The pressure at which the one-way valve 530 is fully open is the second pressure. The first pressure is less than the second pressure.
[0069] Since the first pressure is less than the second pressure, the one-way valve 530 will not be fully opened, but only slightly open, thereby ensuring that ozone and a small amount of water flow back to the inlet pipe 100 through the one-way valve 530.
[0070] In this embodiment, a filter element 230 is provided in the drainage section of the water tank 200. The filter element 230 is used to filter and absorb ozone. The filter element 230 includes an activated carbon filter cartridge.
[0071] In actual operation, the dual circulation loop of ozone cannot ensure the complete recovery of ozone. However, the ozone discharged through the drain section of the water tank 200 can be absorbed by the filter element 230, thereby further reducing the possibility of ozone leakage.
[0072] Compared to the water inlet of water tank 200, the drain of water tank 200 is closer to the top of water tank 200. This design can improve the collection rate of undissolved ozone in water tank 200, so that more ozone can accumulate in gas chamber 220 and be collected during the discharge of water.
[0073] like Figures 1-3 As shown, a disinfection device 240 is installed on the water tank 200, which is used to disinfect and sterilize the water in the water tank 200. In addition to disinfecting the water with ozone, the disinfection device 240 on the water tank 200 can further improve the disinfection effect on the water.
[0074] The disinfection device 240 includes an ultraviolet lamp. One end of the ultraviolet lamp is fixed to the top of the water tank 200, and the other end extends to the bottom of the inner cavity of the water tank 200. Specifically, the base of the ultraviolet lamp is fixed to the top of the water tank 200 and located outside the inner cavity of the water tank 200; the lamp body is located inside the inner cavity of the water tank 200, and one end of the lamp body extends to the bottom of the inner cavity of the water tank 200. This allows the water at the bottom of the water tank 200 to also play a disinfection role, thereby enhancing the disinfection effect.
[0075] There are multiple ultraviolet lamps arranged in an array, with gaps between adjacent ultraviolet lamps.
