Referring to fig. 1 to 3, a hypochlorous acid generator according to an embodiment of the present invention includes a water supply pipe 100 and an electrolytic bath 200 for supplying electrolyte to the water supply pipe 100.

The water supply pipe 100 has a water inlet end and a water outlet end, the water inlet end is connected with a water supply device 110, and a proportional valve 120, a pressure limiting valve 130, an electromagnetic valve 140 and a mixing pipe 150 are sequentially arranged between the water inlet end and the water outlet end along the water flowing direction; the feeding end of the electrolytic cell 200 is connected to a feeding device 210 for feeding the material thereto, and the discharging end is connected to the mixing pipe 150 to mix the material in the mixing pipe 150 to form hypochlorous water. The electrolyte in the electrolytic cell 200 is mainly hydrochloric acid and sodium chloride.

In some embodiments of the present invention, the feeding device 210 is a feeding pump, one end of the feeding pump is connected to the raw material tank 220, and the other end is connected to the feeding end of the electrolytic cell 200. Specifically, the outlet flow of the feed pump is 4.5ml/min; the raw material tank 220 is filled with prepared electrolyte, and the electrolyte is supplied to the electrolytic cell 200 by a supply pump during the water production process.

It is conceivable that a concentration detection device or the like is provided in the electrolytic cell 200 to control the start and stop of the feed pump by detecting the concentration of the electrolyte in the electrolytic cell 200. When the concentration in the electrolytic bath 200 is lower than the lowest value of the set range value of the concentration detection device, starting the feeding pump to feed into the electrolytic bath 200; when the concentration of the electrolyte in the electrolytic bath 200 reaches the maximum value of the set range value of the concentration detection means, the supply of the electrolyte is stopped.

In some embodiments of the present invention, the feeding pump is a peristaltic pump, and the peristaltic pump has the advantages of no pollution, high precision, low shearing force, good sealing performance, simple maintenance, bidirectional equal flow conveying capacity, etc.; the peristaltic pump has good self-priming capability, can idle, can prevent backflow, and cannot damage any part of the pump under the condition of no liquid idle running; can generate 98% vacuum degree; there are no valves, mechanical seals, and packing seals, and there are no such factors that create leaks and maintenance; the solid, liquid or gas-liquid mixed phase fluid can be easily conveyed, and the diameter of the solid contained in the fluid is allowed to reach 40% of the inner diameter of the tubular element; can convey various materials with grinding, corrosion and oxygen sensitive characteristics, various foods and the like; only the hose is a part needing to be replaced, and the replacement operation is extremely simple; the conveyed product does not come into contact with any parts other than the hose. The raw material in the application is corrosive, so a peristaltic pump is preferred, but the raw material can be replaced according to actual requirements.

Referring to fig. 1, in some embodiments of the present invention, a washing pump 230 for washing the electrolytic bath 200 is connected in parallel to the feeding device 210. Specifically, the purge pump 230 is also a peristaltic pump, but the unit flow rate of the purge pump 230 can be up to 100ml/min at most, which is greater than the flow rate of the feed pump. After the hypochlorous acid generator is operated for a set time (e.g., 5 hours or 6 hours, which may be set according to actual conditions), the supply pump is stopped for one minute, and then the cleaning pump 230 is started for one minute to clean the electrolytic cell 200 with a large amount of electrolyte.

The purpose of the design of the cleaning pump 230 is that since part of the residual liquid in the electrolytic cell 200 remains during each electrolysis, the residual liquid accumulation after long-time operation can cause the change of the electrolyte concentration in the electrolytic cell 200, which not only affects the electrolysis efficiency, but also can affect the service life of the electrolytic cell due to the easy temperature rise of the electrolytic cell, and the problems can be better solved by adding the cleaning pump 230. During the operation of the washing pump 230, a large amount of residual liquid in the electrolytic cell 200 enters the water supply pipe, thereby ensuring the electrolysis efficiency of the electrolytic cell 200 and facilitating the control of the operation temperature of the electrolytic cell 200.

In some embodiments of the present invention, the set flow rate of the proportional valve 120 is 2L/min for limiting the water supply rate of the water supply pipe 100; the pressure limiting valve 130 is set to range from 0.2MPa to 0.4MPa for limiting the pressure within the water supply pipe 100.

It should be noted that the flow rate of the metering valve 120 should be set to be equivalent to the electrolysis efficiency of the electrolytic cell 200, and the feed rate of the peristaltic pump should be also equivalent to the electrolysis efficiency of the electrolytic cell 200, so as to ensure the stability of the disinfection effect of the produced water.

In some embodiments of the present invention, referring to fig. 1, a check valve 160 is further disposed between the mixing tube 150 and the solenoid valve 140. The check valve 160 is provided to prevent the electrolyte from flowing back into the water supply pipe 100 in case of a sudden power failure or a malfunction of the mixing pipe 150. The solenoid valve 140 functions to control the on/off of the liquid in the water supply pipe 100.

In some embodiments of the present invention, the mixing pipe 150 includes a contracting section 151 and an expanding section 152, the contracting section 151 gradually decreases in the water flow direction, and the expanding section 152 gradually increases in the water flow direction; the discharge end of the cell 200 is connected to the expansion section 152. Specifically, referring to fig. 2, the length of the contracting section 151 in the axial direction is smaller than that of the expanding section 152 in the axial direction, a connecting hole 153 is formed at one end of the expanding section 152 close to the contracting section 151, and the discharge end of the electrolytic cell 200 is communicated with the connecting hole 153. By providing the mixing tube 150 with a converging section 151 and a diverging section 152, the device is simple, while the head loss is small because its diverging section 152 gradually slows the fluid, reducing turbulence.

Referring to fig. 3, in some embodiments of the present invention, a degassing structure 170 is further disposed on the water supply pipe 100, the degassing structure 170 is disposed at an end of the mixing pipe 150 away from the solenoid valve 140, that is, in the water flow direction, the degassing structure 170 is disposed behind the mixing pipe 150. The degassing structure 170 extends in a radial direction of the water supply pipe 100, and is vertically disposed; the degassing structure 170 is hollow inside and has a gas permeable membrane 171 at the end. The degassing structure 170 is penetrated through the center thereof to be in line communication with the water supply pipe 100, and has an air permeable film 171 attached to an end thereof, and the air permeable film 171 allows gas to pass therethrough but does not allow liquid to pass therethrough, so that gas in the line of the water supply pipe 100 can be effectively removed, thereby reducing damage to the line of the water supply pipe 100.

In some embodiments of the present invention, referring to fig. 1, a flow meter 180 is further disposed on the water supply pipe 100 for monitoring the flow rate of the water supplied through the water supply pipe 100.
