In conventional technology, ion exchange is used to convert sodium hypochlorite solution into hypochlorous acid solution, and sodium ions in the sodium hypochlorite solution are replaced by hydrogen ions through displacement.

[0003] In the existing technology for generating hypochlorous acid solution from sodium hypochlorite solution, the sodium hypochlorite solution is directly introduced into the H-type strong acid cation exchange resin layer for reaction. The sodium hypochlorite solution has a fixed travel distance, and the travel distance cannot be adjusted according to the amount of input solution. In addition, the sodium ion content of the resin after displacement is high, and if the solution is not replaced, it may affect subsequent displacement. During the solution replacement process, the resin surface may not be in a horizontal state due to solution exchange, which affects the displacement travel distance. SUMMARY

[0010] Further, the replacement mechanism includes a replacement generator, the replacement generator is connected with the workbench, the replacement generator includes a preparation tank and an H type strong acid cation exchange resin layer, the preparation tank is placed on the workbench, the H type strong acid cation exchange resin layer is placed below the inside of the preparation tank, the preparation tank is connected with the liquid replacement mechanism, the replacement mechanism further includes an injection pipe, a liquid sampling pipe and an injection port, the injection pipe and the liquid sampling pipe are placed on the workbench, one end of the injection pipe is in communication with the injection port, the end of the injection pipe away from the injection port is in communication with the initial solution storage tank, the injection pipe is connected with the replacement generator, the injection pipe is connected with the preparation tank, the injection port is connected with the replacement generator, the injection port is placed in the preparation tank, the longitudinal section of the injection port is trapezoidal, the bottom surface and the side surface of the injection port are provided with a plurality of liquid holes, the liquid sampling pipe is connected with the replacement generator, the liquid sampling pipe is connected with the preparation tank, one end of the liquid sampling pipe is placed above the H type strong acid cation exchange resin layer in the preparation tank, the other end of the liquid sampling pipe is in communication with the hypochlorous acid water storage tank, the injection pipe is connected with the pipeline adjusting mechanism, and the injection pipe is connected with the liquid replacement mechanism.

[0011] In the displacement mechanism, the mechanism is used for replacing sodium ions in sodium hypochlorite solution into hydrogen ions to become hypochlorous acid solution, and the sodium hypochlorite solution flows out from the injection pipe to the injection port to the H-shaped strong acid cation exchange resin layer from the initial solution storage tank, the injection port is provided with liquid holes at the bottom and the side, so that the solution not only flows out from the bottom, but also flows out from the side, which can speed up the displacement speed and improve the displacement efficiency. After the sodium hypochlorite solution passes through the H-shaped strong acid cation exchange resin layer and becomes hypochlorous acid solution, the hypochlorous acid solution is sucked away by the liquid sampling pipe above the H-shaped strong acid cation exchange resin layer and flows into the hypochlorous acid water storage tank.

[0012] Further, the pipeline adjusting mechanism includes a flow detection device, the flow detection device and the injection pipe are connected, the flow detection device includes an electrode plate and an electrified wire, the electrode plate is provided with two, the two electrode plates are placed in the injection pipe, the two electrode plates are placed in parallel, the two electrode plate connecting lines are perpendicular to the solution flow direction, the two electrode plates are connected with the electrified wire, the pipeline adjusting mechanism further includes a pipeline length adjusting device, the pipeline length adjusting device and the workbench are connected, the pipeline length adjusting device and the injection pipe are connected, the pipeline length adjusting device includes a fixed rod and a push hydraulic cylinder, the fixed rod and the workbench are connected, the push hydraulic cylinder fixed end and the workbench are tightly connected, the push hydraulic cylinder output end and the injection pipe are tightly connected, the fixed rod is provided with two groups, the first fixed rod and the injection pipe are tightly connected, the first fixed rod is placed on the side of the injection pipe close to the initial solution storage tank, the second fixed rod and the injection pipe are movably connected, the fixed rod includes a ring and a rod body, the rod body and the ring are tightly connected, the rod body and the workbench are tightly connected, the first ring and the injection pipe are tightly connected, and the second ring and the injection pipe are slidably connected.

[0013] In the pipeline adjusting mechanism, the mechanism is used to adjust the position of the injection port in the H-shaped strong acidic cation exchange resin layer, to adjust the displacement stroke according to the amount of sodium hypochlorite solution input, to reduce the useless stroke, to improve the efficiency, to detect the solution flow through the flow detection device, to make the electrode plate conductive, to generate electromotive force when the sodium hypochlorite solution passes through, to convert into current, to determine the amount of solution according to the existing time, and to be unable to form an effective current loop when there is no solution flowing through. If the current loop exists for a long time, the amount of input sodium hypochlorite solution is large. At this time, the hydraulic cylinder is pushed to shorten to be parallel to the injection pipe and the bottom surface of the workbench, and is placed below the H-shaped strong acidic cation exchange resin layer. After the sodium hypochlorite solution is injected, the displacement stroke is long during the process of reaching the top of the H-shaped strong acidic cation exchange resin layer, and the displacement can be more sufficient. If the existing time is short, the amount of input sodium hypochlorite solution is small. At this time, the hydraulic cylinder is lifted to make the injection pipe be lifted between the two fixed rods, and the fixed rod close to the initial solution storage tank and the injection pipe are tightly connected. Therefore, when being lifted, the injection pipe and the injection port in the H-shaped strong acidic cation exchange resin layer move upward, the injected sodium hypochlorite solution is in the upper position of the H-shaped strong acidic cation exchange resin layer, and the displacement stroke is short. Through such a design, the displacement stroke can be changed according to the amount of input sodium hypochlorite solution, the displacement efficiency is improved, and the useless displacement is reduced.

[0014] Further, the liquid changing mechanism includes a solution detection device, the solution detection device is placed on the workbench, the solution detection device is connected with the preparation tank, the solution detection device includes a monochromatic light source and a photoresistor, the photoresistor is not less than three, the photoresistor is tightly connected with the inner wall of the preparation tank, the photoresistor is placed at the lowermost part of the preparation tank, the monochromatic light source is tightly connected with the workbench, the light beam of the monochromatic light source is obliquely incident on the preparation tank, the part close to the monochromatic light source of the preparation tank is made of transparent material, and the photoresistor is placed on one side of the light emitted by the monochromatic light source.

[0015] In the solution detection device, the device is used to detect the concentration of the resin displaced from the H-shaped strong acidic cation exchange resin layer. The monochromatic light source is obliquely incident into the resin layer. The refractive index of air, the surface of the preparation tank and the resin layer gradually increases. Therefore, after being incident, the incident angle is greater than the refraction angle. When the device starts to start, the solution detection device starts synchronously. When the displacement has not been replaced, after the light is incident, it is refracted to a photoresistor. In the process of displacement, hydrogen ions are replaced by sodium ions, and the refractive index decreases. Therefore, the light will be shifted, the refraction angle will be increased, and the light will be shone on other photoresistors. The resistance value corresponding to the photoresistor is reduced. The concentration of hydrogen ions and sodium ions in the resin solution is detected according to different photoresistors, so as to change the liquid changing speed.

[0016] Further, the liquid changing mechanism further comprises a liquid changing device, the liquid changing device is fixedly connected with the workbench, the liquid changing device comprises an input pipe, an output pipe, a proportional valve, an input tank and an output tank, the proportional valve, the input tank and the output tank are arranged on the workbench, one end of the input pipe is communicated with the tank body below the preparation tank, the other end of the input pipe is communicated with the proportional valve, the proportional valve is connected with the input tank through a pipeline, one end of the output pipe is communicated with the tank body below the preparation tank, the other end of the output pipe is communicated with the input tank, the liquid changing mechanism further comprises a porous plate, the porous plate is fixedly connected with the inner wall of the preparation tank, the porous plate is arranged between the H-shaped strong acid cation exchange resin layer and the upper layer of air, and the injection pipe penetrates through the porous plate.

[0017] In the liquid changing device, the proportional valve is controlled according to the solution detection device, and the injection speed of the H-shaped strong acid cation exchange resin solution is adjusted. Since the molecular weight of sodium ions is greater than that of hydrogen ions, the solution containing sodium ions will move downward in the H-shaped strong acid cation exchange resin layer. The liquid changing device is arranged in the lower half of the H-shaped strong acid cation exchange resin layer, so that after being opened, more solution containing sodium ions can be directly flushed out from the output pipe to the output tank, and the H-shaped strong acid cation exchange resin solution flows into the preparation tank from the input tank through the input pipe. At this time, the content of the H-shaped strong acid cation exchange resin solution in the preparation tank is always more, but there is still a strong acid cation exchange resin Na type solution. Due to the characteristics of the ion selectivity of the acid cation exchange resin that the sodium ion is greater than the hydrogen ion, the hydrogen ion increased after the sodium hypochlorite solution passes through the strong acid cation exchange resin H type is in contact with the strong acid cation exchange resin Na type to cause a not intense ion exchange reaction, so that part of the hydrogen ion is replaced by the sodium ion, so that the pH value of the final solution can be maintained at about 5-6, which can inhibit the generation of chlorine. The porous plate is arranged above the H-shaped strong acid cation exchange resin layer, which can stabilize the resin solution during liquid changing, maintain the level of the resin surface and keep the displacement stroke fixed.

[0018] Compared with the prior art, the present invention has the following beneficial effects: after startup, the present invention provides a displacement mechanism, and after the sodium hypochlorite solution is introduced, the sodium hypochlorite solution is converted into a hypochlorous acid solution through the H-type strongly acidic cation exchange resin; by providing a pipeline adjustment mechanism, the amount of the input sodium hypochlorite solution is detected by the electrode plate; according to the input amount, the hydraulic cylinder is driven to adjust the position of the input pipe in the displacement mechanism; if the amount of the input sodium hypochlorite solution is large, the hydraulic cylinder is pushed to shorten the injection pipe to be parallel to the bottom surface of the workbench and placed below the H-type strongly acidic cation exchange resin layer; in the process of the sodium hypochlorite solution reaching the top of the H-type strongly acidic cation exchange resin layer, its displacement stroke is long, and the displacement can be more fully performed; if the amount of the input sodium hypochlorite solution is small, the hydraulic cylinder is pushed to lift the injection pipe between the two fixed rods, and the injection pipe and the injection port placed in the H-type strongly acidic cation exchange resin layer move upward. The injected sodium hypochlorite solution is located in the upper layer of the H-type strongly acidic cation exchange resin layer, and its displacement stroke is short. The displacement stroke is adjusted according to the amount of solution input to improve the displacement efficiency and reduce useless displacement. By setting a liquid replacement mechanism, the concentration change of the resin solution is detected according to the refraction of light, thereby controlling the proportional valve and adjusting the injection speed of the H-type strongly acidic cation exchange resin solution. Since the molecular weight of sodium ions is greater than that of hydrogen ions, the solution containing sodium ions will move downward in the H-type strongly acidic cation exchange resin layer. Therefore, the liquid replacement device is placed at the lower position of the preparation tank, which can directly replace most of the sodium-containing resin solution. The remaining sodium-containing resin will be replaced again, so that part of the hydrogen ions are replaced by sodium ions, thereby inhibiting the generation of chlorine gas. The porous plate is covered above the H-type strongly acidic cation exchange resin layer, which can stabilize the resin solution, keep the resin surface level, and keep the displacement stroke fixed during liquid replacement.

[0028] In this generating device, the device is used to generate a hypochlorous acid solution from a sodium hypochlorite solution, and replace the sodium ions in the sodium hypochlorite solution using an H-type strongly acidic cation exchange resin.

The liquid replacement mechanism 4 is used to discharge the sodium-containing resin solution in the resin solution that has completed the hydrogen and sodium replacement, and then input a new H-type strongly acidic cation exchange resin solution, so that the resin solution is mostly hydrogen-containing resin solution, facilitating more efficient replacement. At the same time, by setting the mechanism, the upper surface of the resin solution is kept stable and horizontal during the liquid replacement process, and the stroke is fixed, thereby reducing the surging of the resin solution caused by the liquid replacement, resulting in an uneven upper surface and affecting the replacement stroke.

[0029] The main mechanism 1 includes a workbench 11, an initial solution storage tank 12 and a hypochlorous acid water storage tank 13. The initial solution storage tank 12 is placed on the workbench 11, and the hypochlorous acid water storage tank 13 is placed on the workbench 11. The workbench 11 is connected to the replacement mechanism 2, the workbench 11 is connected to the pipeline adjustment mechanism 3, the workbench 11 is connected to the liquid replacement mechanism 4, the initial solution storage tank 12 is connected to the replacement mechanism 2, and the hypochlorous acid water storage tank 13 is connected to the replacement mechanism 2.

[0031] The replacement mechanism 2 includes a replacement generator 21, which is connected to the workbench 11. The replacement generator 21 includes a preparation tank 211 and an H-type strongly acidic cation exchange resin layer. The preparation tank 211 is placed on the workbench 11, and the H-type strongly acidic cation exchange resin layer is placed below the inside of the preparation tank 211.

The injection pipe 22 is connected to the replacement generator 21, and the injection pipe 22 is connected to the preparation tank 211. The injection port 24 is connected to the replacement generator 21, and the injection port 24 is placed in the preparation tank 211. The longitudinal section of the injection port 24 is trapezoidal, and the bottom and side surfaces of the injection port 24 are provided with a plurality of liquid permeable holes. The liquid collection pipe 23 is connected to the replacement generator 21, and the liquid collection pipe 23 is connected to the preparation tank 211. One end of the liquid collection pipe 23 is placed above the H-type strong acid cation exchange resin layer in the preparation tank 211, and the other end of the liquid collection pipe 23 is connected to the hypochlorous acid water storage tank 13. The injection pipe 22 is connected to the pipeline adjustment mechanism 3, and the injection pipe 22 is connected to the liquid replacement mechanism 4.

[0032] In the replacement mechanism 2, this mechanism is used to replace the sodium ions in the sodium hypochlorite solution with hydrogen ions, thereby converting it into a hypochlorous acid solution. The sodium hypochlorite solution flows from the initial solution storage tank 12 through the injection pipe 22 to the injection port 24 and out into the H-type strong acid cation exchange resin layer. The injection port 24 is provided with liquid permeable holes at the bottom and sides, so that the solution can flow out not only from the bottom but also from the sides, which can speed up the replacement and improve the replacement efficiency. After the sodium hypochlorite solution passes through the H-type strong acid cation exchange resin layer and becomes a hypochlorous acid solution, the hypochlorous acid solution is sucked away by the liquid sampling pipe 23 above the H-type strong acid cation exchange resin layer and flows into the hypochlorous acid water storage tank 13.

[0033] The pipeline adjusting mechanism 3 comprises a flow detection device 31 connected with the injection pipe 22, the flow detection device 31 comprises two electrode plates 311 and a power supply wire, the two electrode plates 311 are arranged in the injection pipe 22, the two electrode plates 311 are arranged in parallel, the two electrode plates 311 are perpendicular to the solution flow direction, the two electrode plates 311 are connected with the power supply wire, the pipeline adjusting mechanism 3 further comprises a pipeline length adjusting device 32 connected with the workbench 11, the pipeline length adjusting device 32 is connected with the injection pipe 22, the pipeline length adjusting device 32 comprises a fixed rod 321 and a push hydraulic cylinder 322, the fixed rod 321 is connected with the workbench 11, the push hydraulic cylinder 322 is fixedly connected with the workbench 11 at the output end, the fixed rod 321 is provided with two groups, the first fixed rod 321 is fixedly connected with the injection pipe 22, the first fixed rod 321 is arranged on the side of the injection pipe 22 close to the initial solution storage tank 12, the second fixed rod 321 is movably connected with the injection pipe 22, the fixed rod 321 comprises a ring 3211 and a rod body 3212, the rod body 3212 is fixedly connected with the ring 3211, the rod body 3212 is fixedly connected with the workbench 11, the first ring 3211 is fixedly connected with the injection pipe 22, and the second ring 3211 is slidably connected with the injection pipe 22.

[0034] In the pipeline adjusting mechanism 3, the mechanism is used for adjusting the position of the injection port 24 in the H-shaped strong acid cation exchange resin layer, adjusting the displacement stroke according to the input amount of the sodium hypochlorite solution, reducing the useless stroke, improving the efficiency, detecting the solution flow through the flow detection device 31, conducting the electrode plate 311, generating electromotive force when the sodium hypochlorite solution passes, converting into current, determining the amount of solution according to the existing time, when there is no solution flowing, an effective current loop cannot be formed, if the current loop exists for a long time, the input amount of the sodium hypochlorite solution is large, at this time, the push hydraulic cylinder 322 is shortened to be parallel to the bottom surface of the workbench 11, and is arranged below the H-shaped strong acid cation exchange resin layer, after the sodium hypochlorite solution is injected, the displacement stroke is long during the process of reaching the top of the H-shaped strong acid cation exchange resin layer, and the displacement can be more sufficient; if the existing time is short, the input amount of the sodium hypochlorite solution is small, at this time, the push hydraulic cylinder 322 is lifted, so that the injection pipe 22 is lifted between the two fixed rods 321, and the fixed rod 321 close to the initial solution storage tank 12 is fixedly connected with the injection pipe 22, so that when the injection pipe 22 is lifted, the injection pipe 22 and the injection port 24 arranged in the H-shaped strong acid cation exchange resin layer move upward, the injected sodium hypochlorite solution is arranged in the upper position of the H-shaped strong acid cation exchange resin layer, and the displacement stroke is short. Through such design, the displacement stroke can be changed according to the input amount of the sodium hypochlorite solution, the displacement efficiency is improved, and the useless displacement is reduced.

[0035] The liquid changing mechanism 4 comprises a solution detection device 41, which is arranged on the workbench 11 and connected with the preparation tank 211. The solution detection device 41 comprises a monochromatic light source 411 and a plurality of photoresistors 412. The photoresistors 412 are connected with the inner wall of the preparation tank 211 and arranged at the lowermost position of the preparation tank 211. The monochromatic light source 411 is connected with the workbench 11 and the light beam thereof is obliquely directed to the preparation tank 211. The preparation tank 211 near the monochromatic light source 411 is made of transparent material. The photoresistors 412 are arranged at the side of the light beam of the monochromatic light source 411.

[0036] In the solution detection device 41, the device is used to detect the concentration of the H-type strong acidic cation exchange resin layer. The monochromatic light source 411 is obliquely directed into the resin layer. The refractive index of the air, the surface of the preparation tank 211 and the resin layer gradually increases. Therefore, after the light beam is directed into the resin layer, the incident angle is greater than the refractive angle. When the device is started, the solution detection device 41 is started synchronously. When the resin is not replaced, the light beam is refracted to one photoresistor 412 after being directed into the resin layer. During the replacement process, the hydrogen ions are replaced by sodium ions, and the refractive index decreases. Therefore, the light beam is deviated, the refractive angle increases, and the light beam is directed to other photoresistors 412. The resistance values of the photoresistors 412 corresponding to the hydrogen ions and the sodium ions in the resin solution are reduced. The concentration of the hydrogen ions and the sodium ions in the resin solution is detected according to the different photoresistors 412, so as to change the liquid changing speed.

[0037] The liquid changing mechanism 4 further comprises a liquid changing device 42, which is connected with the workbench 11. The liquid changing device 42 comprises an input pipe 421, an output pipe 422, a proportional valve 423, an input tank and an output tank. The proportional valve 423, the input tank and the output tank are arranged on the workbench 11. One end of the input pipe 421 is connected with the lower tank body of the preparation tank 211, and the other end of the input pipe 421 is connected with the proportional valve 423. The proportional valve 423 is connected with the input tank through a pipeline. One end of the output pipe 422 is connected with the lower tank body of the preparation tank 211, and the other end of the output pipe 422 is connected with the input tank. The liquid changing mechanism 4 further comprises a porous plate 43, which is connected with the inner wall of the preparation tank 211 and arranged between the H-type strong acidic cation exchange resin layer and the upper air. The injection pipe 22 penetrates through the porous plate 43.

[0038] In the liquid exchange device 42, the proportional valve 423 is controlled according to the solution detection device 41, and the injection speed of the H-type strong acid cation exchange resin solution is adjusted. Since the molecular weight of sodium ions is greater than that of hydrogen ions, in the H-type strong acid cation exchange resin layer, the solution containing sodium ions will move downward. The liquid exchange device 42 is placed in the lower half of the H-type strong acid cation exchange resin layer, so after being opened, it can directly flush out the solution containing more sodium ions from the output pipe 422 to the output tank. The H-type strong acid cation exchange resin solution flows from the input tank to the preparation tank 211 through the input pipe 421. At this time, the content of the H-type strong acid cation exchange resin solution in the preparation tank 211 is always more, but there is still a strong acid cation exchange resin Na-type solution. Due to the characteristics of the ion selectivity of the acid cation exchange resin being greater than that of sodium ions, the hydrogen ions in the sodium hypochlorite solution increase after passing through the strong acid cation exchange resin H-type, and the ion exchange reaction between the strong acid cation exchange resin Na-type and the hydrogen ions is not intense, resulting in partial replacement of sodium ions by hydrogen ions. This makes the pH value of the final solution maintain around 5-6, which can inhibit the generation of chlorine gas. The porous plate 43 is covered on the H-type strong acid cation exchange resin layer, which can stabilize the resin solution during liquid exchange, maintain the level of the resin surface, and keep the displacement stroke fixed.

[0039] The working principle of the present application is as follows: after the present application is started, the sodium hypochlorite solution is changed into sodium hypochlorite solution by the H-shaped strong acid cation exchange resin through the setting displacement mechanism 2 after the sodium hypochlorite solution is input, the amount of the input sodium hypochlorite solution is detected by the electrode plate 311 through the setting pipeline adjustment mechanism 3, the position of the input pipe 421 in the displacement mechanism 2 is adjusted according to the input amount by driving the push hydraulic cylinder 322, if the amount of the input sodium hypochlorite solution is large, the push hydraulic cylinder 322 is shortened to be parallel to the bottom surface of the workbench 11, and is placed below the H-shaped strong acid cation exchange resin layer, the displacement stroke is longer during the process that the sodium hypochlorite solution reaches the top of the H-shaped strong acid cation exchange resin layer, and the displacement can be more sufficient; if the amount of the input sodium hypochlorite solution is small, the push hydraulic cylinder 322 is lifted, so that the injection pipe 22 is lifted between the two fixed rods 321, the injection pipe 22 and the injection port 24 in the H-shaped strong acid cation exchange resin layer are moved upward, the displacement stroke is shorter for the injected sodium hypochlorite solution in the upper layer of the H-shaped strong acid cation exchange resin layer, the displacement stroke is adjusted according to the amount of the input solution, the displacement efficiency is improved, and useless displacement is reduced, the concentration change of the resin solution is detected according to the refraction of light, the injection speed of the H-shaped strong acid cation exchange resin solution is adjusted by controlling the proportional valve 423, etc., because the molecular weight of sodium ions is greater than that of hydrogen ions, therefore the solution containing sodium ions will move downward in the H-shaped strong acid cation exchange resin layer, the liquid exchange device 42 is placed at the lower position of the preparation tank 211, and most of the sodium-containing resin solution can be directly displaced, the remaining sodium-containing resin will be displaced again, so that part of the hydrogen ions are replaced by sodium ions, the generation of chlorine gas is inhibited, the porous plate 43 is covered above the H-shaped strong acid cation exchange resin layer, the resin solution can be stabilized during liquid exchange, the resin surface is kept horizontal, and the displacement stroke is kept fixed.
