Description

Technical Field

[0001] The utility model relates to a medical disinfection device, in particular to an acidic electrolyzed water generating device. Technical Background

[0002] An acidic electrolyzed water generator is a device that electrolyzes a low-concentration sodium chloride aqueous solution through a diaphragm electrolytic cell to generate an acidic aqueous solution with low-concentration available chlorine and high oxidation-reduction potential on the anode side. This technology was invented in Japan in 1987 and has been widely applied in the medical and food fields due to its good disinfection and sterilization effects. In 1995, this technology was introduced into China. Although it has a development history of nearly 30 years in China, the actual application situation is not satisfactory. The main reasons are as follows: When the electrolytic cell of the acidic electrolyzed water generator electrolyzes, the electrolyzed water is easily affected by the pressure, flow rate of the pump valve and pipeline, and the environmental temperature and humidity, resulting in unstable water supply flow rate or sodium chloride concentration, thus causing abnormal technical indicators of the produced acidic electrolyzed water and the disinfection and sterilization effect not meeting the requirements. Moreover, when the technical indicators are abnormal, it is very difficult for users to detect them in time, posing a great safety risk.

[0003] In addition, gases such as chlorine gas and reactive oxygen that are not dissolved in water will slowly escape in the storage device during the electrolysis process. The higher the environmental temperature, the greater the escape amount. Over time, it will corrode and damage the equipment itself and other electrical components in the room. These reasons have seriously affected its development and application.

[0004] Therefore, providing a stable flow rate and sodium chloride concentration for the electrolytic water condition of the electrolytic cell, realizing on-line detection of technical indicators, being able to detect in time when the indicators are abnormal, and solving them in a timely and effective manner, and simultaneously purifying and treating harmful gases such as chlorine gas and reactive oxygen that escape are problems that must be solved by the acidic electrolyzed water generator. Summary of the Invention

[0005] In order to effectively solve the problems of unstable technical indicators of the acidic electrolyzed water generated by the acidic electrolyzed water generator and the corrosion of electrical equipment by harmful gases such as chlorine gas and reactive oxygen that escape, the utility model provides an acidic electrolyzed water generating device, which uses an on-line detection device to monitor the technical indicators of the acidic electrolyzed water, and can remotely monitor the working state of the device through a touch display screen or the Internet of Things, and adjust relevant operating parameters of the device to ensure the stability of the technical indicators of the electrolyzed water; at the same time, it can also harmlessly treat harmful gases such as chlorine gas and reactive oxygen that escape to ensure the safety of the device itself and electrical equipment in the room.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: An acidic electrolyzed water generator, comprising a mixing tank, a preparation tank, a brine tank, a brine metering pump, an electrolysis metering pump, a constant temperature electric water heater, an electrolytic cell, an acid water tank, a disproportionation reactor, a constant pressure water supply pump, a water softener and a control system. The water softener and the brine tank are respectively communicated with the mixing tank, and the mixing tank is communicated with the preparation tank. The preparation tank is communicated with the electrolytic cell through the constant temperature electric water heater. It is characterized in that it further comprises an on-line circulation detection device and an Internet of Things device. The anode of the electrolytic cell is respectively communicated with the acid water tank and the disproportionation reactor through a three-way joint, and the cathode of the electrolytic cell is communicated with the disproportionation reactor. The acid water tank is respectively connected with the constant pressure water supply pump and the on-line detection circulation water pump. The lower part of the disproportionation reactor is connected with an external drainage pipeline through an airtight elbow.

[0007] The on-line detection device consists of a circulation water pump, an on-line pH detector, a pH meter controller, an on-line potential detector, a potential meter controller and an analog quantity module. The circulation water pump, the on-line pH detector and the on-line potential detector are successively installed in series in a circulation pipeline. One end of the circulation pipeline is communicated with the bottom of the acid water tank, and the other end is communicated with an interface on the upper part of the side of the acid water tank.

[0008] The on-line pH detector is connected with the pH meter controller, and its detection signal is transmitted to the analog quantity module and then interacts with the PLC controller; the on-line potential detector is connected with the potential meter controller, and its detection signal is transmitted to the analog quantity module and then interacts with the PLC controller.

[0009] The circulation water pump, the on-line pH detector and the on-line potential detector work according to the program set by the PLC controller. The detection frequency is set according to the user's requirements, or a detection instruction is sent or the detection frequency is modified through a remote terminal. When starting the detection, the circulation water pump starts first, and the analog quantity module collects the signals of the on-line pH detector and the on-line potential detector, and then transmits the detection signals to the PLC controller, which are synchronously updated on the Internet of Things computer terminal or the device touch display screen. When the index information is abnormal, an alarm is given, and the abnormal information is sent to the user administrator and the after-sales service center.

[0010] The Internet of Things device consists of a switch, an Internet of Things control box and a computer terminal. The PLC controller interacts with the switch, and the switch is connected with the Internet of Things control box to realize the networking of the Internet of Things and meet the requirement of remotely managing the device through the computer terminal.

[0011] The touch display screen is associated with the switch. The data that needs to be observed by the device is displayed on the touch display screen, and the operation keys set on the touch display screen are used to control and adjust the operation state of the device.

[0012] The liquid inlet end of the brine metering pump extends into the brine tank, and the other end is connected to the mixing tank. Its function is to supply a set amount of saturated sodium chloride solution to the mixing tank. There is a corresponding relationship between its set working time (i.e., the dosage of sodium chloride solution) and the measured available chlorine concentration. After the two are associated through the PLC controller, the available chlorine concentration is displayed on the Internet of Things computer terminal and the device touch display screen. At the same time, the working time of the brine metering pump can be adjusted through the Internet of Things computer terminal or the touch display screen to obtain the required available chlorine concentration.

[0013] The water inlet end of the electrolysis metering pump is connected to the preparation tank, and the water outlet end is connected to the constant temperature water heater, which is used to transport electrolysis water to the electrolytic cell. Using a metering pump for water supply can ensure the stability of the water supply pressure and flow rate, so as to ensure the stability of the electrolysis parameters. The rotation speed of the electrolysis metering pump can be adjusted through the Internet of Things computer terminal or the touch display screen to obtain the required electrolysis water flow rate.

[0014] There are three interfaces at the top of the disproportionation reactor. One is the alkaline water discharge interface, and the alkaline water discharged from the cathode of the electrolytic cell is discharged into the disproportionation reactor through this interface via a pipeline. The second is the acidic water discharge interface. When the electrolytic cell is restarted after standby electrolysis, the acidic oxidation potential water at the initial section of the anode is discharged into the disproportionation reactor through this interface. The third is the waste gas interface, and harmful gases such as chlorine gas and reactive oxygen escaping from the acid water tank are introduced into the disproportionation reactor through this interface. Both the acid water discharge pipe and the waste gas discharge pipe extend below the alkaline water liquid level, so that chlorine gas and reactive oxygen can fully react with the sodium hydroxide solution and water to eliminate harmful gases without adding any chemical reagents.

[0015] There is a gas-tight elbow at the lower part of the disproportionation reactor. The head of the gas-tight elbow faces downward and is immersed below the liquid level, which is used to cut off the communication between the chamber of the disproportionation reactor and the outside world and play a sealing role to prevent the escape of harmful gases that have not fully undergone disproportionation reaction in the disproportionation reactor. The end of the gas-tight elbow is connected to the external drainage pipeline.

[0016] The control system of the present utility model adopts a PLC controller, and the working process is automated.

[0017] The beneficial effects of the present utility model are as follows: By online detecting relevant technical indicators of acidic oxidation potential water and online monitoring the operation status and technical indicators of the equipment through the Internet of Things device, when the indicators are abnormal, the relevant operation parameters of the equipment can be adjusted through the Internet of Things computer terminal or the device touch display screen, effectively ensuring the stability of the technical indicators of acidic oxidation potential water and ensuring the disinfection and sterilization effect. At the same time, harmful gases such as chlorine gas and reactive oxygen escaping from the acid water tank are synchronously introduced into the disproportionation reactor for purification treatment, completely solving the problem of equipment corrosion caused by the escaped waste gas.

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0024] From Figure 1 , Figure 3As can be seen, the utility model includes a mixing tank 1, a preparation tank 5, a brine tank 25, a brine metering pump 26, an electrolysis metering pump 6, a constant temperature electric water heater 7, an electrolytic cell 9, an acid water tank 12, a disproportionation reactor 20, a constant pressure water supply pump 17, a water softener 22, an on-line circulation detection device, an Internet of Things device and a control system. The water softener 22 and the brine tank 25 are respectively communicated with the mixing tank 1, the mixing tank 1 is communicated with the preparation tank 5, the preparation tank 5 is communicated with the electrolytic cell 9 through the constant temperature electric water heater 7, the anodic (+) water outlet end of the electrolytic cell 9 is respectively communicated with the acid water tank 12 and the disproportionation reactor 20 through a three-way joint, the cathodic (-) water outlet end of the electrolytic cell 9 is communicated with the disproportionation reactor 20, the acid water tank 12 is respectively connected with the constant pressure water supply pump 17 and the on-line detection circulation water pump 18, the exhaust pipe on the side is communicated with the disproportionation reactor 20, and the lower part of the disproportionation reactor 20 is connected with an external waste water pipe through a gas-tight elbow 19.

[0025] From Figure 1 it can be seen that there are three interfaces on the upper part of the mixing tank 1, which are respectively connected with the water softener 22, the brine tank 25 and the preparation tank 5. A mixing tank high liquid level sensor 29, a mixing tank low liquid level sensor 28 and a mixing tank submersible pump 27 are installed in the tank. When the liquid level in the tank drops to the position of the mixing tank low liquid level sensor 28, the water softening solenoid valve 23 opens to fill the mixing tank 1 with softened water. When the water level reaches the position of the mixing tank high liquid level sensor 29, the water softening solenoid valve 23 closes to stop adding water. When starting to add softened water, the brine metering pump 26 is started synchronously, and after adding a set amount of saturated sodium chloride solution into the mixing tank 1, it stops working.

[0026] The water softener 22 is connected with the mixing tank 1 through a water softening solenoid valve 23.

[0027] The brine tank 25 is connected with the mixing tank 1 through a brine metering pump 26. The brine metering pump 26 provides a set amount of saturated sodium chloride solution for the mixing tank 1. There is a brine tank low liquid level sensor 24 in the tank. When the oversaturated sodium chloride solution in the tank drops to the low liquid level, the device alarms to prompt the user to supplement a set amount of oversaturated sodium chloride solution. There is a corresponding relationship between the working time of the brine metering pump 26 (i.e., the dosage of sodium chloride solution) and the measured effective chlorine concentration. After the two are associated through the PLC controller 30, the corresponding effective chlorine concentration value is displayed on the Internet of Things computer terminal 37 and the touch display screen 34.

[0028] The preparation tank 5 is a tank for preparing electrolysis water. After the soft water and sodium chloride solution are fully mixed in the mixing tank 1, they are pumped into the preparation tank 5 by the mixing tank submersible pump 27. The electrolysis water in the preparation tank 5 has two characteristics. One is that the sodium chloride solution is evenly mixed and the concentration is stable. The other is that the pressure in the tank is at atmospheric pressure and is not affected by the pressure changes of the tap water pipeline and each pump valve. When the electrolysis water is pumped into the electrolytic cell 9 by the electrolysis metering pump 6, the pressure, flow rate, and uniformity of sodium chloride of the mixed solution are always in a stable state to ensure the stability of electrolysis parameters. The water inlet end of the preparation tank 5 is connected to the mixing tank 1 through the mixing tank submersible pump 27, and the water outlet end is connected to the constant temperature water heater 7 through the electrolysis metering pump 6. There are three liquid level sensors installed in the tank, namely the low liquid level sensor 2 of the preparation tank, the middle liquid level sensor 3 of the preparation tank, and the high liquid level sensor 4 of the preparation tank. The high liquid level sensor 4 of the preparation tank is used to control the water filling height in the tank. When the solution pumped from the mixing tank 1 into the preparation tank 5 reaches the position of the high liquid level sensor 4 of the preparation tank, the mixing tank submersible pump 27 stops adding liquid. The middle liquid level sensor 3 of the preparation tank is used to control the working state of the mixing tank submersible pump 27. When the liquid in the preparation tank 5 drops to the position of the middle liquid level sensor 3 of the preparation tank, the mixing tank submersible pump 27 starts to add liquid to the preparation tank 5. When it is added to the position of the high liquid level sensor 4 of the preparation tank, the mixing tank submersible pump 27 stops adding liquid to meet the demand for electrolysis water. The low liquid level sensor 2 of the preparation tank is used to control the working state of the electrolysis metering pump 6. When the water supply stops or the pump valve fails and cannot supply water, after the liquid in the tank drops to the position of the low liquid level sensor 2 of the preparation tank, the electrolysis metering pump 6 stops working, the electrolysis work process stops, and the equipment returns to the initial standby state.

[0029] The water inlet end of the electrolysis metering pump 6 is connected to the preparation tank 5, and the water outlet end is connected to the constant temperature water heater 7. It is used to transport electrolysis water to the electrolytic cell 9. Using a metering pump for water supply can ensure the stability of water supply pressure and flow rate to ensure the stability of electrolysis parameters.

[0030] The water outlet end of the constant temperature water heater 7 is connected to the water inlet end of the electrolytic cell 9, and the set heating temperature is 30°C. Its working state is controlled by the on / off key on the screen or remotely. It is used to increase the basic water temperature during electrolysis in winter, keep the temperature of the electrolyzed water in a stable range, thus preventing the influence on the technical indicators of the electrolyzed water when the temperature is too low in winter, and improving the use comfort at the same time.

[0031] The electrolytic cell 9 is a diaphragm electrolysis device with 1 water inlet end and 2 water outlet ends. The water inlet end is connected to the water outlet end of the constant temperature water heater 7. One side of the water outlet end is the anode (+), which is connected to the acid water tank 12 through the main flow solenoid valve 10 and to the disproportionation reactor 20 through the branch solenoid valve 8 respectively through a tee joint. The other side is the cathode (-), which is connected to the disproportionation reactor 20.

[0032] After standby, each time the electrolysis workflow is restarted, the branch solenoid valve 8 at the end of the disproportionation reactor 20 opens, and the main solenoid valve 10 at the end of the acid water tank 12 closes. The acidic electrolyzed oxidizing water with unstable initial production and technical indicators is first discharged into the disproportionation reactor 20. After a set time, the main solenoid valve 10 at the end of the acid water tank 12 opens, and the branch solenoid valve 8 at the end of the disproportionation reactor 20 closes. Then the acidic electrolyzed oxidizing water is discharged into the acid water tank 12 for standby. At the other end is the cathode, and the discharged water is alkaline reduced potential water (NaOH solution), which is discharged into the disproportionation reactor 20 through a pipeline.

[0033] There are two interfaces at the top of the acid water tank 12, which are respectively connected to the intake solenoid valve 11 and the anode (+) discharge pipeline of the electrolytic cell 9. There is an exhaust pipe interface at the upper part of the side, which is connected to the disproportionation reactor 20 and extends 1 cm below the alkaline water liquid level 21. When adding acid water into the tank, chlorine gas, reactive oxygen, air, etc. in the acid water tank 12 can only escape into the disproportionation reactor 20 through this pipeline. There are two interfaces at the bottom, one interface is connected to the constant pressure water supply pump 17, and the other interface is connected to the on-line detection circulating water pump 18. An acid water tank high liquid level sensor 13 and an acid water tank low liquid level sensor 14 are installed in the acid water tank 12. The acid water tank low liquid level sensor 14 is installed in the middle and lower part of the tank. When the acid water liquid level in the tank drops to this position, the system commands to start the electrolysis working program to produce acidic electrolyzed oxidizing water and add it into the acid water tank 12. When the acid water liquid level in the tank rises to the position of the acid water tank high liquid level sensor 13, the electrolysis working program stops working and goes into standby. The acid water tank intake valve 11 is a normally closed solenoid valve, which is the intake channel of the acid water tank 12. When the user opens the faucet to use water and the pressure of the constant pressure water supply pipeline drops to the set pressure value, the acid water tank intake valve 11 opens for intake. When the pressure of the constant pressure water supply pipeline rises to the set pressure value, the acid water tank intake valve 11 closes to prevent harmful gases such as chlorine gas and reactive oxygen in the tank from escaping. When the volume of the acid water tank 12 is insufficient, an external acid water tank can be added for expansion.

[0034] From Figure 1 、 Figure 3 As can be seen, the on-line detection device is used to on-line detect the pH value and oxidation-reduction potential value of the acidic electrolyzed oxidizing water, and it is composed of a circulating water pump 18, an on-line pH detector 16, a pH meter controller 31, an on-line potential detector 15, a potentiometer controller 32, and an analog module 33. The circulating water pump 18, the on-line pH detector 16, and the on-line potential detector 15 are all installed in series on the circulating pipeline. One end of the pipeline is connected to the bottom of the acid water tank 12, and the other end is connected to the interface at the upper part of the side of the acid water tank 12, forming a circulation loop with the acid water tank 12.

[0035] From Figure 3As can be seen from [reference], the on-line pH detector 16 is used to detect the pH value of acidic electrolyzed water, and is connected to the pH meter controller 31. Its detection signal is transmitted to the analog module 33 and then interactively accessed with the PLC controller 30.

[0036] The on-line potential detector 15 is used to detect the potential value of acidic electrolyzed water, and is connected to the potentiometer controller 32. Its detection signal is transmitted to the analog module 33 and then interactively accessed with the PLC controller 30.

[0037] The circulating water pump 18, on-line pH detector 16, and on-line potential detector 15 work according to the set program. The detection frequency is set according to user requirements, and detection instructions can also be sent or the detection frequency can be modified at any time through the remote computer terminal 37. When starting the detection, the circulating water pump 18 starts first. The analog module 33 collects the signals of the on-line pH detector 16 and on-line potential detector 15, and then transmits the detection signals to the PLC controller 30, which are synchronously updated on the Internet of Things computer terminal 37 or the device touch display screen 34. When the index information is abnormal, an alarm is given and the abnormal information is sent to the user administrator and the after-sales service center.

[0038] From Figure 1 As can be seen from [reference], the disproportionation reactor 20 is used to eliminate harmful gases such as chlorine and reactive oxygen. There are three interfaces at the top, which are respectively connected to the pipeline branches at the cathode (-) end of the electrolytic cell 9, the anode (+) end of the electrolytic cell 9, and the exhaust pipe interface at the upper part of the acid water tank 12. The pipeline branch at the anode (+) end of the electrolytic cell 9 and the exhaust pipe of the acid water tank 12 both extend below the alkaline water liquid level 21, so that chlorine and reactive oxygen can fully react with the sodium hydroxide solution and water.

[0039] There is an airtight elbow 19 at the lower part of the disproportionation reactor 20. The head of the airtight elbow 19 faces downward and is immersed below the alkaline water liquid level 21, which is used to cut off the connection between the cavity of the disproportionation reactor 20 and the outside world, playing a sealing role to prevent the escape of harmful gases that have not fully undergone disproportionation reaction in the disproportionation reactor 20. The end of the airtight elbow 19 is connected to the external drainage pipeline.

[0040] The inlet of the constant-pressure water supply pump 17 is connected to the acid water tank 12, and the outlet is connected to the external pipeline. Its function is to maintain a certain water supply pressure in the whole pipeline to meet the water use requirements of each water use point.

[0041] The inlet of the water softener 22 is connected to the tap water pipeline, and the outlet is connected to the mixing tank 1 through the water softening solenoid valve 22. It is used to remove metal ions in the tap water so that the total hardness of the water quality for electrolysis meets the requirement of <25 mg / L.

[0042] From Figure 3As can be seen, the Internet of Things devices mainly include a switch 35, an Internet of Things control box 36, a computer terminal 37, etc. The pH meter controller 31 collects electrical signals from the on-line pH value detector 16, and the potentiometer controller 32 collects electrical signals from the on-line potential detector 15 and transmits them to the analog module 33. The PLC controller 30 realizes Internet of Things networking through interactive access with the analog module 33 and the switch 35. The switch 35 is associated with the Internet of Things control box 36 to remotely control the device through the computer terminal 37.

[0043] As can be seen Figure 3 from, by associating the Internet of Things control box 36 through the computer terminal 37, or associating the switch 35 through the touch display screen 34, the PLC controller 30 finally realizes the control of operating parameters such as the working time of the salt solution metering pump 26, the rotation speed of the electrolysis metering pump 6, the on / off state of the circulating water pump 18 and the constant temperature electric water heater, etc., so as to remotely monitor the operating state of the device, adjust the operating parameters, and ensure the stability of the technical indicators of the acidic electrolyzed water.

[0044] The touch display screen 34 is associated with the switch 35 for information mutual access.

[0045] Its working process is as follows:

[0046] Preparation work before starting up: Manually configure supersaturated sodium chloride solution according to the set dosage standard, add it to the salt solution tank 25, and supply water and power to the device.

[0047] As can be seen Figure 1 、 Figure 2 from, after starting up, the touch display screen 34 lights up and the device enters the automatic working state. When it is necessary to increase the basic electrolysis water temperature in winter, press the temperature control key on the touch display screen 34.

[0048] First, the PLC controller 30 judges whether there is a waterless signal from the low liquid level sensor 14 of the acid water tank. If not (no signal), it means there is water in the acid water tank 12 and it stands by. If there is (there is a waterless signal), or after the standby state, after the low liquid level sensor 14 of the acid water tank sends out a waterless signal, the PLC controller 30 then judges whether there is a waterless signal from the liquid level sensor 3 in the preparation tank. If not, the electrolysis tank metering pump 6 and the constant temperature electric water heater 7 are started successively, and the electrolysis tank 9 starts to work to produce acidic electrolyzed water.

[0049] After standby, each time the electrolysis working process is restarted, the main solenoid valve 10 is closed and the branch solenoid valve 8 is opened to discharge the initially produced acidic electrolyzed water with unstable technical indicators into the disproportionation reactor 20. After a set time, the main solenoid valve 10 is opened and the branch solenoid valve 8 is closed to inject the acidic electrolyzed water into the acid water tank 12 for standby.

[0050] When the acidic electrolyzed water in the acid water tank 12 is filled up to the position of the high liquid level sensor 13 of the acid water tank and the no-water signal disappears, the constant temperature electric water heater 7, the electrolytic cell metering pump 6, and the electrolytic cell 9 stop working in sequence and enter the standby state.

[0051] During the operation of the electrolytic cell 9, if the no-water signal appears at the low liquid level sensor 2 of the reserve tank, it may indicate that the water supply pipeline has a water cut or a pump valve failure. At this time, the constant temperature electric water heater 7, the electrolytic cell metering pump 6, and the electrolytic cell 9 stop working in sequence and enter the standby state.

[0052] If the no-water signal appears at the liquid level sensor 3 in the reserve tank, it is necessary to determine whether there is a no-water signal at the low liquid level sensor 28 of the mixing tank. If so, it means that the mixing tank 1 needs to be filled with water. At this time, the soft water solenoid valve 23 is opened to fill the soft water. At the same time, the brine metering pump 26 is started to fill the mixing tank 1 with a set amount of saturated sodium chloride solution and then stops working. When the filled soft water reaches the position of the high liquid level sensor 29 of the mixing tank and the no-water signal disappears, the soft water solenoid valve 23 is closed to stop adding water. Subsequently, the mixing tank submersible pump 27 is started to fill the electrolysis water into the reserve tank 5. When the filled water reaches the position of the high liquid level sensor 4 of the reserve tank and the no-water signal disappears, the mixing tank submersible pump 27 stops working.

[0053] If there is no no-water signal at the low liquid level sensor 28 of the mixing tank, the mixing tank submersible pump 27 is directly started to fill the electrolysis water into the reserve tank 5.

[0054] If the height of the saturated sodium chloride solution in the brine tank 25 drops to the position of the low liquid level sensor 24 of the brine tank, the device alarms to prompt the user to add supersaturated sodium chloride solution.
