Description

Technical Field

[0001] This utility model relates to the field of swimming pool water purification technology, specifically to a diaphragm electrolysis swimming pool water treatment machine. Background Technology

[0002] Hypochlorous acid is a commonly used disinfection method for swimming pool water. However, the actual use of swimming pools requires equipment that can continuously circulate the 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 swimming pool water and continuously produce hypochlorous acid. However, during the electrolysis of swimming pool water, the concentration of hydroxide ions will continue to increase, causing the pH value of the swimming pool water to rise and affecting the treatment effect of the swimming pool water. Utility Model Content

[0003] This utility model provides a diaphragm electrolysis pool water treatment machine to solve the problem that existing pool water disinfection equipment causes the pH value of the pool water to rise, affecting the treatment effect of the pool water.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A diaphragm electrolysis pool water treatment machine is connected to a pool and a wastewater tank. The water discharged from the pool contains sodium chloride. The diaphragm electrolysis pool water treatment machine includes a hollow outer cylinder, and a cylindrical diaphragm is installed inside the outer cylinder. The area inside the diaphragm forms the anode area, and the area between the diaphragm and the outer cylinder forms the cathode area. The diaphragm is permeable to water and can block the permeation of hydroxide ions.

[0006] The bottom of the outer cylinder is equipped with an electrolysis water inlet pipe head that is connected to the anode area. Pool water drawn from the pool enters the diaphragm electrolysis pool water treatment machine through the electrolysis water inlet pipe head. The top of the outer cylinder is equipped with an electrolysis water outlet pipe head that is connected to the anode area. The pool water treated by the diaphragm electrolysis pool water treatment machine flows back to the pool through the electrolysis water outlet pipe head.

[0007] The top of the outer cylinder is provided with an electrolytic waste gas outlet that is connected to the cathode area. The electrolytic waste gas outlet is connected to an exhaust pipe that is connected to the electrolytic water outlet.

[0008] The bottom of the outer cylinder is equipped with an electrolytic wastewater discharge pipeline that is connected to the cathode area and leads to the wastewater pool.

[0009] In a preferred embodiment, the anode region is provided with an anode electrolytic plate as the anode, and the cathode region is provided with a cathode electrolytic plate as the cathode;

[0010] By using a diaphragm to isolate hydroxide ions, the pH value of the pool water is prevented from rising and kept stable within the standard range for pool water, thus ensuring a good purification effect for the pool water.

[0011] In a preferred embodiment, the wastewater discharge pipe head is a three-way pipe head, which is connected to two parallel electrolytic wastewater discharge pipes. One pipe is equipped with a drain solenoid valve, and the other pipe is equipped with a safety valve, so that the diaphragm electrolytic pool water treatment machine can cope with emergency situations where the pressure inside the outer cylinder increases, and assist in the discharge of wastewater through the safety valve.

[0012] Furthermore, the electrolytic waste gas outlet is connected to a solenoid valve with one inlet and two outlets. The electrolytic waste gas outlet is connected to the inlet of the solenoid valve with one inlet and two outlets. One outlet of the solenoid valve with one inlet and two outlets is connected to the atmosphere, and the other outlet is connected to the exhaust pipe, so that the discharge process of electrolytic wastewater is smoother.

[0013] In a preferred embodiment, the outer cylinder is further provided 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, so that the diaphragm electrolysis pool water treatment machine can detect the increase in pressure inside the outer cylinder in a timely manner and discharge hydrogen gas in a timely manner.

[0014] In a preferred embodiment, the outer cylinder is further provided with a wastewater overflow port, the height of which is lower than that of the electrolytic waste gas discharge port; the wastewater overflow port is connected to a wastewater overflow pipe, which is connected to a wastewater pool to prevent wastewater from flowing into the electrolytic waste gas discharge port.

[0015] In a preferred embodiment, a check valve is installed on the wastewater overflow pipeline to prevent wastewater from flowing back into the wastewater pool.

[0016] The beneficial effects of this utility model are as follows:

[0017] The diaphragm electrolysis pool water treatment machine provided by this utility model utilizes the electrolysis of sodium chloride to generate a slightly acidic hypochlorous acid disinfectant.

[0023] 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.

[0024] like Figure 1-3 As shown, this utility model provides a diaphragm electrolysis pool water treatment machine 1, which is mainly used for the circulation treatment of pool water. The pool water in pool 2 is connected to the diaphragm electrolysis pool water treatment machine 1 through the pool outlet pipe 21 and is pumped by the water pump 4. The pool water treated by the diaphragm electrolysis pool water treatment machine 1 flows back to pool 2 through the pool return pipe 22. The gas generated by the electrolysis process of the diaphragm electrolysis pool water treatment machine 1 is guided to the pool return pipe through the exhaust pipe 23 and transported to pool 2 together with the treated pool water. The diaphragm electrolysis pool water treatment machine 1 generates chlorine and hydrogen by electrolyzing sodium chloride in the pool water (sodium chloride can be directly added to pool 2, or an additional salt addition device can be set before the diaphragm electrolysis pool water treatment machine 1). The hydrogen is discharged through the exhaust pipe 23. The chlorine reacts with the pool water to form hypochlorous acid, which can be used for disinfection of pool water.

[0025] Specifically, the diaphragm electrolysis pool water treatment machine 1 includes a hollow outer cylinder 11. A cylindrical diaphragm 12 is disposed inside the outer cylinder 11. The area within the diaphragm 12 forms an anode region 1101 and is provided with an anode electrolysis plate 11011. The area between the diaphragm 12 and the outer cylinder 11 forms a cathode region 1102 and is provided with a cathode electrolysis plate 11021 (the plate-shaped cathode and anode have a larger contact surface with the water, resulting in better electrolysis). The diaphragm 12 is permeable 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 this invention). An electrolysis inlet communicating with the anode region 1101 is provided at the bottom of the outer cylinder 11. The outer cylinder 11 has an electrolytic water outlet 14 connected to the anode area 1101 at the top of the water inlet 13 and the electrolytic water outlet 14 connected to the swimming pool 2. The electrolytic water inlet 13 is connected to the swimming pool water outlet 21 to introduce swimming pool water into the anode area 1101 of the diaphragm electrolytic swimming pool water treatment machine 1. The outer cylinder 11 has an electrolytic waste gas outlet 15 connected to the cathode area 1102 for discharging electrolytic gases at the top of the outer cylinder 11 and the electrolytic waste gas outlet 15 is connected to the exhaust pipe 23. The outer cylinder 11 has a wastewater discharge pipe 16 connected to the cathode area 1102 for discharging electrolytic wastewater at the bottom of the outer cylinder 11 and the wastewater discharge pipe 16 is connected to the electrolytic wastewater discharge pipe 31 and the electrolytic wastewater discharge pipe 31 is connected to the wastewater pool 3.

[0026] When the diaphragm electrolysis pool water treatment machine 1 is working, the pool water enters the anode zone 1101 from the electrolysis inlet pipe 13 and passes through the diaphragm 12 into the cathode zone 1102. Chlorine gas is generated in the anode zone 1101, 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 14. Hydrogen gas is generated in the cathode zone 1102. Hydrogen gas is insoluble in water and floats to the surface and is discharged from the electrolysis waste gas outlet 15. The hydroxide ions generated in the cathode zone 1102 cannot pass through the diaphragm 12, making the water in the cathode zone 1102 alkaline. The alkaline wastewater in the cathode zone 1102 is discharged from the wastewater outlet pipe 16.

[0027] To ensure the continuous and stable operation of the diaphragm electrolysis pool water treatment machine 1, in an improved embodiment of this utility model, the electrolytic wastewater discharge pipeline 31 is provided with two parallel lines (the wastewater discharge pipe head 16 is a three-way pipe head). One line is equipped with a drain solenoid valve 312, and the other line is equipped with a safety valve 311. That is, under normal conditions, the electrolytic wastewater is discharged by controlling the drain solenoid valve 312. In an emergency where the pressure inside the outer cylinder 11 increases, the safety valve 311 can assist in drainage.

[0028] As a further improvement, an inlet-outlet solenoid valve 5 is connected to the electrolytic waste gas outlet 15. The inlet of the electrolytic waste gas outlet 15 is connected to the inlet of the inlet-outlet solenoid valve 5. One outlet of the inlet-outlet solenoid valve 5 is connected to the atmosphere, and the other outlet is connected to the exhaust pipe 23. Under normal operation, the inlet-outlet solenoid valve 5 is connected to the exhaust pipe 23, and the drain solenoid valve 312 is closed. When drainage is required, the drain solenoid valve 312 is opened, and the inlet-outlet solenoid valve 5 is switched to be connected to the atmosphere, which can ensure that the alkaline wastewater in the cathode area 1102 is smoothly discharged from the wastewater pipe head 16.

[0029] Considering the possibility of excessive hydrogen accumulation in the cathode area 1102 during the operation of the diaphragm electrolysis pool water treatment machine 1, in an improved embodiment of this utility model, the outer cylinder 11 is further equipped with a liquid level sensor 17 for monitoring the liquid level in the cathode area 1102 and a pressure sensor 18 for monitoring the internal pressure of the outer cylinder 11; when the pressure sensor 18 detects an increase in the pressure inside the outer cylinder 11 and the liquid level sensor 17 detects a decrease in the liquid level in the cathode area 1102, the system determines that excessive hydrogen has accumulated in the cathode area 1102, and the one-in-two-out solenoid valve 5 switches to be connected to the atmosphere to discharge hydrogen.

[0030] Considering that the liquid level in the cathode area 1102 may be too high during the operation of the diaphragm electrolysis pool water treatment machine 1, causing wastewater to overflow from the electrolysis exhaust gas outlet 15, in an improved embodiment of this utility model, a wastewater overflow port 19 is also provided on the outer cylinder 11. The height of the wastewater overflow port 19 is lower than that of the electrolysis exhaust gas outlet 15. The wastewater overflow port 19 is connected to a wastewater overflow pipe 32, which is connected to the wastewater pool 3. A check valve 321 is installed on the wastewater overflow pipe 32 to prevent the wastewater in the wastewater pool 3 from flowing back.

[0031] The diaphragm electrolysis pool water treatment machine provided by this utility model utilizes the electrolysis of sodium chloride to generate a slightly acidic hypochlorous acid disinfectant. At the same time, it uses a diaphragm to isolate hydroxide ions, preventing the pH value of the pool water from rising and keeping the pH stable within the standard range for pool water, thus ensuring a good purification effect for the pool water.

[0032] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
