Technical Field

[0001] This invention relates to the field of swimming pool water treatment technology, and more specifically to a swimming pool water circulation treatment system. Background Technology

[0002] Hypochlorous acid is a commonly used disinfection method for swimming pool water. However, the actual use of swimming pools requires a system that can continuously circulate the pool water and continuously add hypochlorous acid for disinfection. For example, patent document CN205556329U discloses a swimming pool water disinfection device that uses an electrolytic reactor to electrolyze the pool water and continuously produce hypochlorous acid. However, during the electrolysis of the pool water, the concentration of hydroxide ions will continue to increase, causing the pH value of the pool water to rise and affecting the treatment effect of the pool water. Summary of the Invention

[0003] This invention provides a swimming pool water circulation treatment system to solve the problem that the pH value of the swimming pool water continuously increases during the electrolysis of swimming pool water in existing swimming pool water circulation treatment systems, thus affecting the swimming pool water treatment effect.

[0004] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0005] A swimming pool water circulation treatment system is connected to a swimming pool and a wastewater pool. The swimming pool water discharged from the pool contains sodium chloride. The swimming pool water circulation treatment system includes an inlet, an outlet, a wastewater discharge outlet, an ultraviolet disinfection module, a diaphragm electrolysis module, and a drainage and exhaust system. The drainage and exhaust system includes an electrolytic wastewater discharge pipeline and a first exhaust pipeline.

[0006] The membrane electrolysis module is divided into an anode area and a cathode area by a membrane. The membrane is permeable to water and can block hydroxide ions.

[0007] Pool water flows into the pool water circulation and treatment system from the inlet, passes sequentially through the ultraviolet disinfection module and the anode area of ​​the diaphragm electrolysis module, and flows back to the pool from the outlet.

[0008] The bottom of the cathode area is connected to the electrolytic wastewater discharge pipeline, which is connected to the wastewater pool. The top of the cathode area is connected to the first exhaust pipeline, which is connected to the swimming pool.

[0009] By combining ultraviolet light and hypochlorous acid to disinfect pool water, and further using a diaphragm to isolate hydroxide ions, the pH value of the pool water is inhibited from rising, thus improving the efficiency of pool water treatment.

[0010] As a preferred embodiment, the pool water circulation treatment system is also equipped with a probe flow tank and a flow meter. The probe flow tank is equipped with various sensors to obtain parameters such as temperature and composition of the pool water flowing through the probe flow tank, and the flow meter is used to obtain the flow rate of the water flowing through the flow meter.

[0011] As a preferred embodiment, the ultraviolet disinfection module includes a lower support, a tube, an upper support, and an ultraviolet lamp kit. There are three tubes arranged longitudinally in parallel. The upper ends of the three tubes are connected to the upper support, and the lower ends of the three tubes are connected to the lower support. Pool water is introduced into the ultraviolet disinfection module from the upper support, flows through the three tubes in sequence, and is then led out of the ultraviolet disinfection module through the lower support.

[0012] An irradiation hole is provided on the side of the upper support away from the tube, which is used to install a UV lamp kit to disinfect the pool water inside the tube by UV irradiation.

[0013] By using multiple tubes arranged in parallel, the size of the ultraviolet disinfection module is reduced.

[0014] In a further improved embodiment, a first upper pipe cap, a second upper pipe cap, and a third upper pipe cap are formed on the side of the upper support near the pipe. The first upper pipe cap, the second upper pipe cap, and the third upper pipe cap are each connected to a pipe. The first upper pipe cap and the second upper pipe cap are not directly connected, and the first upper pipe cap and the third upper pipe cap are also not directly connected. The second upper pipe cap and the third upper pipe cap are directly connected. The side of the upper support is provided with an ultraviolet disinfection pool water inlet for introducing pool water. The ultraviolet disinfection pool water inlet is connected to the first upper pipe cap.

[0015] The lower support has a first lower cap, a second lower cap, and a third lower cap on the side near the pipe. The first lower cap and the first upper cap are respectively connected to the two ends of the same pipe. The second lower cap and the second upper cap are respectively connected to the two ends of the same pipe. The third lower cap and the third upper cap are respectively connected to the two ends of the same pipe. The first lower cap and the second lower cap are directly connected. The third lower cap and the second lower cap are not directly connected. The third lower cap and the first lower cap are also not directly connected. The side of the lower support is provided with an ultraviolet disinfection pool water outlet for leading out the treated pool water. The ultraviolet disinfection pool water outlet is connected to the third lower cap.

[0016] In another further improved embodiment, an exhaust port is formed on the side of the upper support away from the tube, and the exhaust port is connected to the first exhaust pipe.

[0017] By connecting three tubes in series, the ultraviolet disinfection module has a compact structure and minimal impact on the pressure and flow rate of the pipeline system.

[0018] In another further improved embodiment, the drainage and venting system also includes a drain pipe, and a drain hole is formed on the lower support. The drain pipe connects the drain hole and the wastewater pool. A drain valve is installed on the drain pipe so that the pool water in each pipe can be drained through the drain pipe, which is convenient for maintenance.

[0019] In a preferred embodiment, the diaphragm electrolysis module includes a hollow outer cylinder, a cylindrical diaphragm disposed inside the outer cylinder, a region inside the diaphragm serving as the anode region and provided with an anode electrolysis plate, and a region between the diaphragm and the outer cylinder serving as the cathode region and provided with a cathode electrolysis plate.

[0020] The bottom of the outer cylinder is provided with an electrolytic water inlet pipe that communicates with the anode area, and the top of the outer cylinder is provided with an electrolytic water outlet pipe that communicates with the anode area. The electrolytic water outlet pipe is connected to the swimming pool, and the first exhaust pipe is connected to the electrolytic water outlet pipe.

[0021] The electrolysis inlet pipe is connected to the ultraviolet disinfection pool water outlet, which introduces the pool water into the anode area of ​​the diaphragm electrolysis module;

[0022] The top of the outer cylinder is provided with an electrolytic waste gas outlet that communicates with the cathode area, and the electrolytic waste gas outlet is connected to the first exhaust pipe;

[0023] The bottom of the outer cylinder is equipped with a wastewater discharge pipe that is connected to the cathode area, and the wastewater discharge pipe is connected to the electrolytic wastewater discharge pipeline;

[0024] By separately drawing out electrolysis waste gas and electrolysis wastewater, the pH value of the pool water is kept stable while the pressure inside the diaphragm electrolysis module is kept stable.

[0025] In a further improved embodiment, the electrolytic wastewater discharge pipeline is provided with two parallel lines, one of which is equipped with a drain solenoid valve and the other with a safety valve;

[0026] An inlet-outlet solenoid valve is connected to the electrolytic waste gas outlet. The outlet of the electrolytic waste gas is connected to the inlet of the inlet-outlet solenoid valve. One outlet of the inlet-outlet solenoid valve is connected to the atmosphere, and the other outlet is connected to the first exhaust pipe. This makes the discharge process of electrolytic wastewater smoother and ensures the discharge of electrolytic wastewater in emergency situations.

[0027] In another further improved embodiment, the outer cylinder is equipped with a liquid level sensor for monitoring the liquid level in the cathode area and a pressure sensor for monitoring the internal pressure of the outer cylinder, ensuring the discharge of electrolytic wastewater in emergency situations.

[0028] In another further improved embodiment, a wastewater overflow port is also provided on the outer cylinder, the height of which is lower than that of the electrolytic waste gas discharge port; the drainage and exhaust system also includes a wastewater overflow pipe, which connects the wastewater overflow port and the wastewater pool, and a check valve is installed on the wastewater overflow pipe to prevent electrolytic wastewater from entering the waste gas discharge port and to prevent wastewater from flowing back into the wastewater pool.

[0029] The beneficial effects of this invention are as follows:

[0030] The swimming pool water circulation treatment system provided by this invention combines ultraviolet light and hypochlorous acid to disinfect the swimming pool water, and uses a diaphragm to isolate hydroxide ions and inhibit the increase of pH value in the swimming pool water, thus having a high swimming pool water treatment efficiency.

Detailed Implementation

[0043] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0044] like Figure 1-10 As shown, this embodiment of the invention provides a swimming pool water circulation and treatment system, which is assembled into a box shape by a panel 1 and an outer frame 2. The swimming pool water circulation and treatment system is equipped with a touch screen 3 for user interaction, an inlet 4 for introducing pool water to be treated, an outlet 5 for discharging disinfectant, an electrical connector 6 for providing power and transmitting electrical signals to the swimming pool water circulation and treatment system, and a wastewater outlet 7 for discharging wastewater. The inlet 4 is connected to a swimming pool 15 outside the swimming pool water circulation and treatment system. The pool water in the swimming pool 15 is introduced into the inlet 4 by a water pump 17. Sodium chloride is added to the water in the swimming pool 15, that is, the swimming pool water introduced into the swimming pool water circulation and treatment system contains sodium chloride. The outlet 5 is also connected to the swimming pool 15, and the disinfectant is drawn out into the swimming pool 15 to disinfect the pool water. The wastewater outlet 7 is connected to a wastewater pool 16 outside the swimming pool water circulation and treatment system, and the wastewater generated during the treatment process is discharged into the wastewater pool 16.

[0045] To achieve the pool water treatment function of the pool water circulation system, the system includes an electrical control box 9, an ultraviolet disinfection module 11, a diaphragm electrolysis module 13, and a drainage and exhaust system 14. The drainage and exhaust system 14 includes an electrolytic wastewater discharge pipe 1401 and a first exhaust pipe 1402. Pool water in the pool 15 flows into the ultraviolet disinfection module 11 from the inlet 4 for ultraviolet disinfection, and then enters the diaphragm electrolysis module 13. The diaphragm electrolysis module 13 generates hydrogen, chlorine, and alkaline wastewater containing hydroxide ions by electrolyzing sodium chloride. Chlorine dissolves in water to generate... Hypochlorous acid, generated by electrolysis, flows out of outlet 5 to pool 15. Wastewater generated by diaphragm electrolysis module 13 is collected through electrolysis wastewater discharge pipe 1401 and discharged through wastewater outlet 7 to wastewater pool 16. Gas generated during the electrolysis process of diaphragm electrolysis module 13 is collected through first exhaust pipe 1402 and led out of outlet 5 to pool 15. The electrical control box 9 is electrically connected to electrical connector 6, ultraviolet disinfection module 11, drainage and exhaust system 14 and diaphragm electrolysis module 13. The electrical control box 9 stores a control program for controlling the operation of the pool water circulation treatment system.

[0046] To facilitate the specific installation layout of the electrical control box 9, the ultraviolet disinfection module 11, and the diaphragm electrolysis module 13 within the swimming pool water circulation treatment system, an installation frame 12 is provided within the swimming pool water circulation treatment system. The installation frame 12 is constructed by welding and assembling profiles into a frame structure and is fixedly installed inside the swimming pool water circulation treatment system, providing support for the installation of the electrical control box 9, the ultraviolet disinfection module 11, and the diaphragm electrolysis module 13.

[0047] To obtain parameters of the pool water before treatment and to obtain the flow rate of the pool water introduced into the pool water circulation treatment system in real time, in one embodiment of the present invention, the pool water circulation treatment system is further provided with a probe flow tank 8 and a flow meter 10, which are electrically connected to the electrical control box 9 respectively. The pool water introduced into the pool water circulation treatment system from the inlet 4 passes through the probe flow tank 8 and the flow meter 10 before entering the ultraviolet disinfection module 11. The probe flow tank 8 is equipped with various sensors such as temperature sensors and solution concentration sensors to obtain parameters such as temperature and composition of the pool water flowing through the probe flow tank 8. The flow meter 10 is used to obtain the flow rate of the water flowing through the flow meter 10.

[0048] As a major improvement of the present invention, the ultraviolet disinfection module 11 includes a lower support 1101, a tube 1102, an upper support 1103, and an ultraviolet lamp kit 1104. There are three tubes 1102, which are arranged longitudinally in parallel. The upper ends of the three tubes 1102 are connected to the upper support 1103, and the lower ends of the three tubes 1102 are connected to the lower support 1101. Pool water is introduced into the ultraviolet disinfection module 11 from the upper support 1103, flows through the three tubes 1102 in sequence, and is then led out of the ultraviolet disinfection module 11 through the lower support 1101. That is, the three tubes 1102 are connected in series through the upper support 1103 and the lower support 1101.

[0049] Specifically, on the side of the upper support 1103 near the tube 1102, a first upper tube cap 11031, a second upper tube cap 11032, and a third upper tube cap 11033 are formed. Each of these caps connects to a tube 1102. The first upper tube cap 11031 and the second upper tube cap 11032 are not directly connected, nor are the first upper tube cap 11031 and the third upper tube cap 11033. The second upper tube cap 11032 and the third upper tube cap 11033 are directly connected. The upper support 1103 is connected to the side of the upper support 1103, which is provided with an ultraviolet disinfection pool water inlet 11034 for introducing pool water. The ultraviolet disinfection pool water inlet 11034 is connected to the first upper cap 11031. The upper support 1103 is provided with three irradiation holes 11035 on the side away from the tube 1102, which are respectively located at the first upper cap 11031, the second upper cap 11032 and the third upper cap 11033. These holes are used to install the ultraviolet lamp kit 1104 to disinfect the pool water in the tube 1102 by ultraviolet irradiation.

[0050] The lower support 1101 has a first lower cap 11011, a second lower cap 11012, and a third lower cap 11013 formed on the side near the tube 1102. The first lower cap 11011 and the first upper cap 11031 are respectively connected to the two ends of the same tube 1102. The second lower cap 11012 and the second upper cap 11032 are respectively connected to the two ends of the same tube 1102. The third lower cap 11013 and the third upper cap 11033 are respectively connected to the same tube. The two ends of 1102 are directly connected: the first lower cap 11011 and the second lower cap 11012 are directly connected, while the third lower cap 11013 and the second lower cap 11012 are not directly connected, and the third lower cap 11013 and the first lower cap 11011 are also not directly connected. The side of the lower support 1101 is provided with an ultraviolet disinfection pool water outlet 11015 for leading out the treated pool water. The ultraviolet disinfection pool water outlet 11015 is connected to the third lower cap 11013.

[0051] This achieves the series connection of the three tubes 1102, and the flow sequence of pool water within the UV disinfection module 11 is as follows: "UV disinfection pool water inlet 11034 - first upper cap 11031 - tube 1102 - first lower cap 11011 - second lower cap 11012 - tube 1102 - second upper cap 11032 - third upper cap 11033 - tube 1102 - third lower cap 11013 - UV disinfection pool water outlet 11015". This series design ensures a reasonable flow rate of pool water within the UV disinfection module 11 and guarantees sufficient irradiation time for the UV lamp assembly 1104. It also avoids excessively drastic changes in the cross-sectional area of ​​the flow channel within the UV disinfection module 11, which could lead to high local pressure, thus ensuring the service life of the UV disinfection module 11.

[0052] Furthermore, considering that the pool water flows in the ultraviolet disinfection module 11, the air in the pool water is prone to accumulate at the top of the tube 1102. This would cause most of the ultraviolet lamp kit 1104 to be exposed to the air, making it difficult to dissipate heat and posing a safety hazard. Therefore, in an improved embodiment of the present invention, the upper support 1103 forms two vent holes 11036 on the side away from the tube 1102. One vent hole is connected to the first upper tube cap 11031, and the other vent hole 11036 is connected to the second upper tube cap 11032 (in fact, the vent hole 11036 is also connected to the third upper tube cap 11034). The vent hole 11036 is connected to the first exhaust pipe 1402, thereby drawing out the air accumulated at the top of the tube 1102.

[0053] Considering that the pool water in each pipe 1102 needs to be drained during maintenance of the ultraviolet disinfection module 11, in an improved embodiment of the present invention, the drainage and venting system 14 further includes a drain pipe 1403. Two drain holes 11014 are formed on the lower support 1101, one of which is connected to the first lower pipe cap 11011, and the other is connected to the second lower pipe cap 11012 (and also to the third lower pipe cap 11013). The drain pipe 1403 connects the drain holes 11014 and the wastewater tank 16, and a drain valve 14031 is installed on the drain pipe 1403. When maintenance is required, the pool water in each pipe 1102 can be drained by opening the drain valve 14031.

[0054] Similarly, as a major improvement of the present invention, the diaphragm electrolysis module 13 mainly includes a hollow outer cylinder 1301, with a cylindrical diaphragm 1310 disposed inside the outer cylinder 1301. An anode electrolysis plate 1311 is disposed within the diaphragm 1310, forming an anode region 13011. A cathode electrolysis plate 1309 is disposed between the diaphragm 1310 and the outer cylinder 1301, forming a cathode region 13012. The diaphragm 1310 is permeable to water and allows sodium and hydrogen ions to pass through, but blocks hydroxide ions from passing through (diaphragms that achieve this function are existing technology, and their specific structure is not a necessary technical feature of the present invention). An electrolysis water inlet pipe 1303 communicating with the anode region 13011 is disposed at the bottom of the outer cylinder 1301, and an electrolysis water inlet pipe 1303 communicating with the anode region 13011 is disposed at the top of the outer cylinder 1301. The electrolytic water outlet pipe 1302 is connected to the zone 13011 and is connected to the swimming pool 15. The aforementioned first exhaust pipe 1402 is connected to the electrolytic water outlet pipe 1302. The electrolytic water inlet pipe 1303 is connected to the ultraviolet disinfection pool water outlet 11015, which introduces the pool water into the anode zone 13011 in the diaphragm electrolysis module 13. The top of the outer cylinder 1301 is provided with an electrolytic waste gas outlet 1304, which is connected to the cathode zone 13012 and is used to discharge electrolytic gas. The electrolytic waste gas outlet 1304 is connected to the first exhaust pipe 1402. The bottom of the outer cylinder 1301 is provided with a wastewater discharge pipe 1308, which is connected to the cathode zone 13012 and is used to discharge electrolytic wastewater. The wastewater discharge pipe 1308 is connected to the electrolytic wastewater discharge pipe 1401.

[0055] When the diaphragm electrolysis module 13 is working, pool water enters the anode region 13011 from the electrolysis inlet pipe 1303 and passes through the diaphragm 1310 into the cathode region 13012. Chlorine gas is generated in the anode region 13011, and the chlorine gas further dissolves in the pool water to generate hypochlorous acid, thereby forming a disinfectant that flows out from the electrolysis outlet pipe 1302. Hydrogen gas is generated in the cathode region 13012. Hydrogen gas is insoluble in water and floats to the surface and is discharged from the electrolysis waste gas outlet 1304. The hydroxide ions generated in the cathode region 13012 cannot pass through the diaphragm 1310, making the water in the cathode region 13012 alkaline. The alkaline wastewater in the cathode region 13012 is discharged from the wastewater outlet pipe 1308.

[0056] To ensure the continuous and stable operation of the diaphragm electrolysis module 13, in an improved embodiment of the present invention, two parallel discharge pipes 1401 for electrolytic wastewater are provided, one equipped with a drain solenoid valve 14011 and the other with a safety valve 14012; a solenoid valve 1307 with one inlet and two outlets is connected to the electrolytic waste gas outlet 1304, the outlet 1304 being connected to the inlet of the solenoid valve 1307, one outlet of the solenoid valve 1307 being connected to the atmosphere, and the other outlet being connected to the first exhaust pipe 1402; the diaphragm electrolysis module 13 thus has the function of discharge... In normal operation, the water function is as follows: the inlet-outlet solenoid valve 1307 is connected to the first exhaust pipe 1402, and the drain solenoid valve 14011 is closed. When drainage is required, the drain solenoid valve 14011 is opened, and the inlet-outlet solenoid valve 1307 is switched to be connected to the atmosphere, which ensures that the alkaline wastewater in the cathode area 13012 is smoothly discharged through the wastewater pipe 1308. In the event of a system failure, when the internal pressure in the outer cylinder 1301 increases due to the continuous generation of hydrogen gas by electrolysis, the safety valve 14012 is opened to allow the alkaline wastewater in the cathode area 13012 to be discharged through the wastewater pipe 1308.

[0057] Considering the possibility of excessive hydrogen accumulation in the cathode region 13012 during the operation of the diaphragm electrolysis module 13, in an improved embodiment of the present invention, the outer cylinder 1301 is further equipped with a liquid level sensor 1305 for monitoring the liquid level in the cathode region 13012 and a pressure sensor 1306 for monitoring the internal pressure of the outer cylinder 1301; when the pressure sensor 1306 detects an increase in the pressure inside the outer cylinder 1301 and the liquid level sensor 1305 detects a decrease in the liquid level in the cathode region 13012, the system determines that excessive hydrogen has accumulated in the cathode region 13012, and the one-in-two-out solenoid valve 1307 switches to communicate with the atmosphere to discharge hydrogen.

[0058] Considering that the liquid level in the cathode area 13012 may be too high during the operation of the diaphragm electrolysis module 13, causing wastewater to overflow from the electrolysis exhaust outlet 1304, in an improved embodiment of the present invention, a wastewater overflow outlet 1312 is also provided on the outer cylinder 1301, and the height of the wastewater overflow outlet 1312 is lower than that of the electrolysis exhaust outlet 1304; the drainage and exhaust system 14 also includes a wastewater overflow pipe 1404, which connects the wastewater overflow outlet 1312 and the wastewater pool 16, and a check valve 14041 is installed on the wastewater overflow pipe 1404 to prevent the wastewater in the wastewater pool 16 from flowing back.

[0059] The swimming pool water circulation treatment system provided by this invention features a compact ultraviolet disinfection module that has minimal impact on pipeline system pressure and flow rate. The diaphragm electrolysis module isolates OH- ions, generating a slightly acidic HOC I disinfectant that inhibits pH rise and maintains pH stability within the standard range for swimming pool water. This invention combines ultraviolet light and hypochlorous acid for disinfection of swimming pool water, and utilizes a diaphragm to isolate hydroxide ions and inhibit pH rise, resulting in high swimming pool water treatment efficiency.

[0060] The embodiments described above merely illustrate implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
