[0054] Compared with the prior art, the beneficial effects of the present invention are that the stability of the electrolysis process and the quality of the product are ensured by real-time monitoring and controlling the key parameters in the electrolysis process, the key features in the electrolytic cell are monitored in real time, and the electrolysis parameters are automatically adjusted according to the preset judgment conditions and thresholds, so as to realize the automation and intelligent control of the electrolysis process, and the efficiency of the electrolysis process can be improved by accurately controlling the flow rate and stirring rate of the electrolyte and optimizing the electrolysis current, thereby shortening the production cycle and increasing the output of sodium hypochlorite, and through real-time monitoring and feedback control, the equipment can respond to changes in the electrolysis process in a timely manner, ensure the continuity and stability of the electrolysis process, and reduce production interruptions caused by operating errors or equipment failures, and through accurate control of the parameters in the electrolysis process, the quality of the generated sodium hypochlorite product can be guaranteed to be stable, so as to realize the automation, intelligence and high efficiency of the electrolytic sodium hypochlorite production, and improve the production efficiency and product quality.

[0055] By real-time monitoring of the generation of anode bubbles, the electrolysis conditions can be adjusted in time, such as increasing stirring to promote the reaction of chlorine and hydroxide ions, thereby increasing the production of sodium hypochlorite and reducing the overflow of chlorine. The setting of the pre-reaction time allows the system to perform more accurate analysis and adjustments after the electrolysis conditions tend to stabilize, ensuring that the electrolysis process is carried out under optimal conditions. By real-time monitoring of the sodium hypochlorite concentration in the anode area, it can be ensured that the concentration of sodium hypochlorite generated meets the quality standards. By monitoring the distribution of anode bubbles, timely measures can be taken to reduce the overflow of chlorine, which not only increases the production of sodium hypochlorite, but also reduces environmental pollution. Continuous Monitoring the generation of cathode bubbles helps to evaluate the stability of the electrolysis process and promptly detect and deal with abnormal situations in the production process. By real-time monitoring of the sodium chloride concentration in the middle area of ​​the electrolytic cell, the continuous input of sodium chloride can be compensated to maintain the continuity and stability of the electrolysis process. The integration of intelligent equipment realizes the automated control of the electrolysis process, reduces human intervention, and reduces the risk of operational errors. By continuously producing sodium hypochlorite and supplying electrolyte at a certain rate, production efficiency is improved, production cycle is shortened, and the production efficiency and quality of sodium hypochlorite are improved. The production process is also automated, intelligent, and environmentally friendly.

[0056] By analyzing the anode bubble generation in real time and automatically issuing an adjustment signal based on the analysis results, real-time monitoring and rapid response to the electrolysis process are achieved. By comparing the real-time anode sodium chloride concentration and the real-time cathode sodium chloride concentration, the deviation of the sodium chloride concentration in the electrolytic cell can be discovered and corrected in time to maintain the stability of the electrolysis process. The actual production target is determined based on the real-time sodium hypochlorite concentration to ensure product quality and reduce the generation of unqualified products. According to the received adjustment signal, the flow opening of the flow control valve or the stirring rate of the stirring component is accurately adjusted to optimize the electrolysis conditions. By real-time monitoring of the adjustment results of the adjustment module, the initial control current is corrected to achieve continuous optimization of the electrolysis parameters. Through automated adjustment and optimization, manual intervention is reduced and production efficiency is improved. Real-time monitoring and adjustment ensure the concentration and quality of sodium hypochlorite and improve the market competitiveness of the product. It can automatically adjust according to different production conditions to enhance the adaptability and flexibility of the equipment.

[0057] By quickly identifying the distribution quantity and change rate of anode bubbles and responding to changes in the electrolysis process in a timely manner, the electrolysis process can be optimized through monitoring and adjustment, chlorine overflow can be reduced, and the output of sodium hypochlorite can be increased. By controlling the quantity and change rate of anode bubbles, the concentration and quality of sodium hypochlorite can be ensured to meet production quality requirements. By adjusting the stirring rate, chlorine overflow can be reduced, which not only increases the output of sodium hypochlorite but also reduces environmental pollution. It can automatically send adjustment signals without human intervention, thereby improving the automation level of the production line. It can dynamically adjust according to real-time data to adapt to different production conditions, realize the automation, intelligence and efficiency of the electrolytic sodium hypochlorite production process, and improve production efficiency and product quality.

[0058] By accurately monitoring the key parameters in the electrolysis process and making timely adjustments based on these parameters, and by monitoring the real-time middle sodium chloride concentration and cathode bubble generation, the sodium chloride concentration in the electrolytic cell can be balanced to ensure the output and quality of sodium hypochlorite. Abnormal conditions in the production process can be discovered in time and corresponding adjustment measures can be taken. By issuing process adjustment signals, the flow opening can be dynamically adjusted to optimize the electrolysis process and improve production efficiency. Decisions can be made automatically based on monitoring data, reducing manual intervention and improving the level of automation. Changes in the electrolysis process can be responded to in real time, and adjustments can be made quickly to reduce the time of production interruptions. By controlling bubble distribution and sodium chloride concentration, safety risks that may be caused by unstable electrolysis process are reduced. Based on analysis of real-time data, the production process can be continuously optimized to improve the scientificity and accuracy of production. Through multiple judgments and adjustments, the continuity and stability of the electrolysis process can be ensured, reducing production fluctuations.

[0059] The stirring rate and flow opening are dynamically adjusted according to the real-time data in the electrolysis process to adapt to the changes in the electrolytic cell. According to different adjustment signal types, the adjustment range of the stirring rate and flow opening can be accurately controlled to ensure accurate control of the electrolysis process. By timely adjusting the stirring rate and flow opening, the stability of the electrolysis process can be effectively maintained and production fluctuations can be reduced. By adjusting the stirring rate and flow opening, the system can optimize the electrolysis efficiency and increase the output of sodium hypochlorite. By increasing the stirring rate, the overflow of chlorine is reduced, the utilization rate of raw materials is improved, and environmental pollution is reduced.

[0060] By monitoring the adjustment results of the adjustment module in real time, the adjustment effect can be evaluated more accurately, thereby improving the accuracy of the overall adjustment. It can be determined whether the initial control current needs to be corrected based on the adjustment change degree and the final adjustment result, thereby ensuring the stability of the electrolysis process. The initial control current can be accurately corrected according to the instructions of the correction judgment unit to optimize the electrolysis process. The automated operation of the correction module reduces manual intervention and improves the automation level of the production line. It can dynamically adjust the control current based on real-time monitoring data and quickly respond to changes in the electrolysis process. By accurately controlling the current, the production efficiency of sodium hypochlorite can be improved. By maintaining the stability of the electrolysis process, the quality of the sodium hypochlorite product is improved, and the intelligent, precise and efficient production process of the electrolytic sodium hypochlorite is realized, thereby improving production efficiency and product quality.

[0071] See also Figure 1 As shown, the present invention provides an intelligent device based on electrolytic reaction integrated sodium hypochlorite, comprising:

[0072] An electrolyte supply tank 1, which is used to supply electrolyte to the electrolytic cell 6 according to a preset initial flow opening;

[0076] A stirring assembly, comprising a plurality of stirring rods 5, arranged in the electrolytic tank 6, for evenly distributing the electrolyte in the electrolytic tank 6;

[0077] The central control assembly (not shown) is connected to the flow control valve 2, the power supply 3, the electrolytic cell monitoring component and the stirring component respectively; when the electrolytic reaction passes through the pre-reaction time, the central control assembly obtains the preliminary real-time monitoring data corresponding to the preliminary judgment key feature, performs a preliminary judgment based on the preliminary real-time monitoring data to determine whether to start the process judgment mode, or determines the type of preliminary adjustment signal, obtains the preliminary adjustment result based on the preliminary adjustment signal, and determines whether to perform a correction on the initial control current based on the preliminary adjustment result; obtains the process real-time monitoring data of the process judgment key feature according to the process judgment mode, performs a process judgment based on the process real-time monitoring data to determine whether an abnormality occurs in the actual electrolytic process, issues a verification signal based on the occurrence of the abnormality, obtains the verification result based on the verification signal, and determines whether to start the final judgment mode, or determines the type of process adjustment signal, obtains the process adjustment result based on the process adjustment signal, and determines whether to perform a secondary correction on the initial control current based on the process adjustment result; obtains the final real-time monitoring data of the final judgment key feature according to the final judgment mode, and performs a final judgment based on the final real-time monitoring data to determine whether the actual production target is qualified, or issues an alarm signal.

[0078] In this embodiment, the stirring assembly includes a plurality of stirring rods 5 to achieve uniform distribution of the electrolyte in the electrolytic cell 6. The number of the stirring rods 5 is determined according to the actual electrolysis specifications. If the electrolytic cell size corresponding to the actual electrolysis specifications is larger and the electrolyte mass is higher, multiple stirring rods 5 should be provided. Only two stirring rods 5 are drawn in the figure. In this embodiment, the actual number of stirring rods 5 is not specifically limited and will not be repeated here.

[0079] In the specific implementation process, salt is added to the electrolyte supply tank 1, and water is added to dissolve it to prepare an electrolyte of target concentration. The power supply 3 is turned on to supply direct current to the electrolytic cell 6. The electrolyte is transported to the electrolytic cell 6 through the supply pipeline and flows between the anode and the cathode. At the anode, the chloride ions lose electrons and are oxidized to generate chlorine gas. The chlorine gas further reacts with hydroxide ions in the electrolyte to generate sodium hypochlorite and sodium chloride. At the cathode, water molecules accept electrons for reduction reaction to generate hydrogen gas and hydroxide ions.

[0080] Specifically, the embodiment of the present invention monitors and controls the key parameters in the electrolysis process in real time to ensure the stability of the electrolysis process and the quality of the product.

Through real-time monitoring and feedback control, the equipment can respond to changes in the electrolysis process in a timely manner, ensure the continuity and stability of the electrolysis process, and reduce production interruptions caused by operating errors or equipment failures. By accurately controlling the parameters in the electrolysis process, the quality of the generated sodium hypochlorite product can be guaranteed to be stable, thereby realizing the automation, intelligence and efficiency of the electrolytic sodium hypochlorite production, and improving the production efficiency and product quality.

[0081] Specifically, in this embodiment, the electrolytic cell monitoring assembly includes: a number of image monitors and a number of concentration monitors;

[0082] A first image monitor 41, which is used to monitor the anode liquid level of the electrolytic cell 6 in real time to obtain the anode bubble generation situation;

[0083] A second image monitor 42, which is used to monitor the cathode liquid level of the electrolytic cell 6 in real time to obtain the cathode bubble generation situation;

[0084] A first concentration monitor 43, which is used to monitor the sodium chloride concentration in the anode area of ​​the electrolytic cell 6 in real time to obtain a real-time anode sodium chloride concentration;

[0085] A second concentration monitor 44, which is used to monitor the sodium hypochlorite concentration in the anode area of ​​the electrolytic cell 6 in real time to obtain the real-time sodium hypochlorite concentration;

[0086] A third concentration monitor 45, which is used to monitor the sodium chloride concentration in the cathode region of the electrolytic cell 6 in real time to obtain a real-time cathode sodium chloride concentration;

[0087] a fourth concentration monitor 46, which is used to monitor the sodium chloride concentration in the middle area of ​​the electrolytic cell 6 in real time to obtain a real-time sodium chloride concentration in the middle area;

[0088] Among them, the key features for preliminary judgment include: bubble distribution on the anode liquid surface; the key features for process judgment include: bubble distribution on the cathode liquid surface, sodium chloride concentration in the anode area, sodium chloride concentration in the cathode area and sodium chloride concentration in the middle area; the key features for final judgment include: sodium hypochlorite concentration in the anode area.

[0089] In the specific implementation process, the first image monitor 41 is a camera or a photoelectric sensor installed above the anode of the electrolytic cell, which is used to capture the image information of the anode liquid surface; the second image monitor 42 is a camera or a photoelectric sensor installed above the cathode of the electrolytic cell, which is used to capture the image information of the cathode liquid surface; the first concentration monitor 43 monitors the sodium chloride concentration in the anode area of ​​the electrolytic cell in real time to obtain the change of the sodium chloride concentration in the anode area, thereby controlling the electrolyte concentration and ensuring the electrolysis efficiency. In the specific implementation process, an online ion selective electrode sensor or a spectrometer can be used to measure the sodium chloride concentration; the second concentration monitor 44 monitors the sodium hypochlorite concentration in the anode area of ​​the electrolytic cell in real time to obtain the generation of sodium hypochlorite and ensure the product quality. In the specific implementation process, an online ultraviolet visible spectrophotometer or a chloride ion selective photometer can be used. The third concentration monitor 45 monitors the sodium chloride concentration in the cathode area of ​​the electrolytic cell in real time to obtain the change of the sodium chloride concentration in the cathode area, thereby controlling the electrolyte concentration. In the specific implementation process, an online ion selective electrode sensor or a spectrometer can be used; the fourth concentration monitor 46 monitors the sodium chloride concentration in the middle area of ​​the electrolytic cell in real time to obtain the change of the sodium chloride concentration in the middle area of ​​the electrolytic cell to ensure the uniformity of the electrolysis process. An online ion selective electrode sensor or a spectrometer can be used. Each monitor is used to ensure the stability of the electrolysis process and the quality of the product. Through real-time monitoring and feedback, the central control assembly can adjust the electrolysis parameters in time according to the monitoring data to optimize the electrolysis process. In this embodiment, the actual equipment type of each monitor is not specifically limited and will not be repeated here.

[0090] During the electrolysis process, not all chlorine generated at the anode reacts with hydroxide ions to generate sodium hypochlorite, and part of the chlorine may overflow the liquid surface, especially when the electrolysis conditions are unstable or there is not enough stirring. Therefore, in order to increase the output of sodium hypochlorite and reduce the overflow of chlorine, in this embodiment, a first image monitor 41 is provided at the anode liquid surface of the electrolytic cell 6 to obtain the anode bubble generation situation, that is, the overflow of chlorine. By analyzing the overflow of chlorine, it is determined whether the electrolysis conditions are stable or whether measures (such as increasing stirring) need to be taken to promote the reaction of chlorine and hydroxide ions. In addition, in this embodiment, a pre-reaction time is provided, which is determined according to historical electrolysis data to measure whether the electrolysis conditions have stabilized after the pre-reaction time. At this time, the overflow of chlorine is analyzed to determine whether measures (such as increasing stirring) need to be taken to promote the reaction of chlorine and hydroxide ions;

[0091] During the electrolysis process, the hydrogen generated at the cathode is insoluble in the electrolyte and will overflow the liquid surface. Therefore, a second image monitor 42 is provided at the cathode liquid surface of the electrolytic cell 6 to obtain the cathode bubble generation situation, that is, the hydrogen overflow situation. By analyzing the hydrogen overflow situation, it is measured whether the production process of sodium hypochlorite generated at the anode is abnormal;

[0092] In this embodiment, the integration process of the intelligent device integrating sodium hypochlorite is to continuously produce sodium hypochlorite. In the specific implementation process, in order to continuously produce sodium hypochlorite, the electrolyte in the electrolyte supply tank 1 is continuously introduced into the electrolytic cell at a certain rate. However, for the continuous production process, it is necessary to ensure that the sodium chloride concentration in the electrolytic cell 6 is maintained at a certain level, and it is necessary to continuously monitor the sodium chloride concentration in the electrolytic cell 6 to compensate for the continuous input of sodium chloride to achieve the continuity of the electrolysis process; therefore, a fourth concentration monitor 46 is provided in the middle area of ​​the electrolytic cell 6 to monitor the sodium chloride concentration in real time, thereby providing an overall concentration level. Since the middle area is a mixed area of ​​feed and discharge, it can reflect the average state of the electrolyte in the electrolytic cell 6. In this embodiment, the middle area does not specifically refer to the junction of the cathode electrolytic chamber and the anode electrolytic chamber, but refers to the middle area of ​​the electrolytic cell. This area may be between the cathode and the anode, but is not necessarily located exactly at their junction;

[0093] In the specific implementation process, the actual production target generated, that is, sodium hypochlorite needs to be collected and stored, so the concentration needs to be monitored before collection to determine whether the actual production target concentration is qualified. Since sodium hypochlorite is obtained by the reaction of chlorine and hydroxide ions in the anode area, the second concentration monitor 44 is set in the anode area of ​​the electrolytic cell to obtain the real-time sodium hypochlorite concentration.

[0094] Specifically, the embodiment of the present invention can timely adjust the electrolysis conditions by real-time monitoring of the generation of anode bubbles, such as increasing stirring to promote the reaction of chlorine and hydroxide ions, thereby increasing the yield of sodium hypochlorite and reducing the overflow of chlorine. The setting of the pre-reaction time allows the system to perform more accurate analysis and adjustment after the electrolysis conditions tend to be stable, ensuring that the electrolysis process is carried out under optimal conditions. By real-time monitoring of the sodium hypochlorite concentration in the anode area, it can be ensured that the concentration of the generated sodium hypochlorite meets the quality standard. By monitoring the distribution of anode bubbles, measures can be taken in time to reduce the overflow of chlorine, which not only increases the yield of sodium hypochlorite, but also reduces the cycle. Environmental pollution, continuous monitoring of cathode bubble generation is helpful to evaluate the stability of the electrolysis process, timely discover and deal with abnormal situations in the production process, and through real-time monitoring of the sodium chloride concentration in the middle area of ​​the electrolytic cell, the continuous input of sodium chloride can be compensated to maintain the continuity and stability of the electrolysis process. The integration of intelligent equipment realizes the automatic control of the electrolysis process, reduces manual intervention, and reduces the risk of operating errors. By continuously producing sodium hypochlorite and supplying electrolyte at a certain rate, the production efficiency is improved, the production cycle is shortened, the production efficiency and quality of sodium hypochlorite are improved, and the production process is automated, intelligent and environmentally friendly.

[0095] See also Figure 2 As shown, it is a structural schematic diagram of the central control assembly in the intelligent device based on the electrolytic reaction integrated sodium hypochlorite; wherein, the central control assembly includes: a preliminary judgment module, a process judgment module, a final judgment module, an adjustment module and a correction module;

[0096] The preliminary judgment module is used to analyze the anode bubble generation situation to obtain an actual anode bubble data set, and determine to start the process judgment mode according to the actual anode bubble data set, or to issue a type of preliminary adjustment signal, or to issue a type of preliminary adjustment signal;

[0097] The process judgment module is used to determine whether to issue the verification signal according to the real-time middle sodium chloride concentration and the cathode bubble generation situation, obtain the real-time anode sodium chloride concentration and the real-time cathode sodium chloride concentration according to the verification signal, compare the real-time anode sodium chloride concentration and the real-time cathode sodium chloride concentration, and determine to start the final judgment mode according to the comparison result, or issue a type one process adjustment signal, or issue a type two process adjustment signal;

[0098] The final judgment module is used to determine whether the actual production target is qualified according to the real-time sodium hypochlorite concentration, or to issue an alarm signal;

[0099] The adjustment module is connected to the preliminary judgment module and the process judgment module respectively, and is used to receive and send out various adjustment signals, and adjust the flow opening of the flow control valve or the stirring rate of the stirring component accordingly according to the various adjustment signals;

[0100] The correction module is used to monitor the adjustment result of the adjustment module in real time, and perform several corrections on the initial control current according to the adjustment result.

[0101] Specifically, the embodiment of the present invention realizes real-time monitoring and rapid response of the electrolysis process by analyzing the generation of anode bubbles in real time and automatically issuing an adjustment signal according to the analysis result. By comparing the real-time anode sodium chloride concentration and the real-time cathode sodium chloride concentration, the deviation of the sodium chloride concentration in the electrolytic cell can be discovered and corrected in time to maintain the stability of the electrolysis process. The actual production target is determined to be qualified according to the real-time sodium hypochlorite concentration, thereby ensuring the product quality and reducing the generation of unqualified products. According to the received adjustment signal, the flow opening of the flow control valve or the stirring rate of the stirring component is accurately adjusted to optimize the electrolysis conditions. By real-time monitoring of the adjustment result of the adjustment module, the initial control current is corrected to achieve continuous optimization of the electrolysis parameters. Through automated adjustment and optimization, manual intervention is reduced and production efficiency is improved. Real-time monitoring and adjustment ensure the concentration and quality of sodium hypochlorite, improve the market competitiveness of the product, and can be automatically adjusted according to different production conditions, thereby enhancing the adaptability and flexibility of the equipment.

[0102] See also Figure 5 As shown, it is a flow chart of the preliminary judgment process; wherein, the preliminary judgment module includes: a first judgment unit and a first comparison unit;

[0103] The first determination unit is used to analyze the anode bubble generation situation to obtain the actual anode bubble distribution quantity, and determine to start the stability determination mode according to the actual anode bubble distribution quantity and a preset anode bubble distribution quantity threshold, or to send the first type of preliminary adjustment signal;

[0104] The first comparison unit, based on the stability judgment mode, obtains the actual anode bubble change rate within a fixed time period, and determines to start the process judgment mode according to the actual anode bubble change rate combined with a preset anode bubble rate threshold, or sends the second type of preliminary adjustment signal;

[0105] Wherein, if the actual anode bubble distribution number is greater than or equal to the anode bubble distribution number threshold, the first determination unit determines to send the type of preliminary adjustment signal, and if the actual anode bubble distribution number is less than the anode bubble distribution number threshold, the first determination unit determines to start the stability judgment mode;

[0106] If the actual anode bubble change rate is less than the anode bubble rate threshold, the first comparison unit determines to start the process judgment mode; if the actual anode bubble change rate is greater than or equal to the anode bubble rate threshold, the first comparison unit determines to send the second type of preliminary adjustment signal;

[0107] The actual anode bubble data set includes: the actual anode bubble distribution quantity and the actual anode bubble change rate.

[0108] In this embodiment, the distribution number of anode bubbles directly reflects the generation of chlorine during the electrolysis process, which is an important indicator of electrolysis efficiency. If the number of bubbles is too large, it means that too much chlorine overflows during the electrolysis process, affecting the yield and quality of sodium hypochlorite. Therefore, the aforementioned type of preliminary adjustment signal is issued for timely adjustment. The preset anode bubble distribution number threshold is a benchmark for judging whether the electrolysis process is within a normal range. If the actual anode bubble distribution number exceeds this threshold, a type of preliminary adjustment signal is issued to change the stirring rate (increase the stirring rate) to reduce the overflow of chlorine and restore the electrolysis yield. After the stable judgment mode is turned on, it is determined that the number of bubbles has been qualified, and the changes in the anode bubbles are continuously monitored to ensure that The bubble generation rate, that is, whether the electrolysis reaction is stable, and the anode bubble rate threshold are used as a benchmark to determine whether the bubble changes are within an acceptable range. If the change rate exceeds this threshold, it indicates that the electrolysis process has experienced large fluctuations, that is, the electrolysis process is unstable, indicating that although the number of bubbles is qualified, the stirring rate still needs to be adjusted due to the unqualified bubble generation rate, and a second type of preliminary adjustment signal (reducing the stirring rate) is issued; in the specific implementation process, the specific setting of the anode bubble distribution number threshold and the anode bubble rate threshold are affected by the production quality requirements and historical production data of sodium hypochlorite. Through the monitoring and adjustment mechanism, the intelligent equipment can ensure the continuity and stability of the electrolysis process and improve the production efficiency and quality of sodium hypochlorite.

[0109] Specifically, the embodiment of the present invention responds to changes in the electrolysis process in a timely manner by quickly identifying the distribution number and change rate of anode bubbles, and can optimize the electrolysis process through monitoring and adjustment, reduce chlorine overflow, and increase the output of sodium hypochlorite. By controlling the number and change rate of anode bubbles, the concentration and quality of sodium hypochlorite can be ensured to meet production quality requirements. By adjusting the stirring rate, chlorine overflow is reduced, which not only increases the output of sodium hypochlorite but also reduces environmental pollution. The adjustment signal can be automatically sent without manual intervention, thereby improving the automation level of the production line, and can be dynamically adjusted according to real-time data to adapt to different production conditions, thereby realizing the automation, intelligence and efficiency of the electrolytic sodium hypochlorite production process, and improving production efficiency and product quality.

[0110] See also Figure 3 As shown, it is a structural schematic diagram of a process judgment module in an intelligent device based on electrolytic reaction integrated sodium hypochlorite, wherein the process judgment module includes: a process analysis unit and a second comparison unit;

[0111] The process analysis unit is used to determine the number of items that meet a single determination condition in the real-time central sodium chloride concentration and the cathode bubble generation situation, and determine whether to issue the verification signal or issue the first type of process adjustment signal according to the number of items;

[0112] The second comparison unit calculates the absolute value of the sodium chloride concentration difference between the real-time anode sodium chloride concentration and the real-time cathode sodium chloride concentration based on the verification signal, and determines to start the final judgment mode according to the absolute value of the sodium chloride concentration difference, or sends the second type process adjustment signal.

[0113] See also Figure 6 As shown, it is a workflow diagram of the process analysis unit; wherein, the process analysis unit includes: a first process determination subunit, an acquisition subunit and a second process determination subunit;

[0114] The first process determination subunit determines that the real-time middle sodium chloride concentration meets the single determination condition when the real-time middle sodium chloride concentration is less than or equal to a preset middle sodium chloride concentration standard threshold value;

[0115] The acquisition subunit is used to determine the actual cathode bubble distribution quantity according to the cathode bubble generation situation, and determine that the cathode bubble generation situation meets the single determination condition based on the actual cathode bubble distribution quantity being less than or equal to a preset cathode bubble distribution quantity threshold;

[0116] The second process determination subunit determines to send the verification signal when the number of items is equal to 0, and determines to send the first type of process adjustment signal when the number of items is greater than 0;

[0117] Among them, when the real-time central sodium chloride concentration is greater than the preset central sodium chloride concentration standard threshold, it is determined that the real-time central sodium chloride concentration does not meet the single judgment condition; based on the actual cathode bubble distribution number being greater than the preset cathode bubble distribution number threshold, it is determined that the cathode bubble generation situation does not meet the single judgment condition.

[0118] In the specific implementation process, the real-time middle sodium chloride concentration and the cathode bubble generation are two key indicators of the stability of the electrolysis process. By evaluating whether these two indicators meet the preset single judgment condition, it can be comprehensively judged whether the electrolysis process is within the normal range. If the real-time middle sodium chloride concentration is lower than the middle sodium chloride concentration standard threshold, that is, it meets the single judgment condition, it means that the concentration of the sodium chloride solution in the electrolytic cell 6 cannot support the continuous production of sodium hypochlorite. If the actual cathode bubble distribution number is lower than the cathode bubble distribution number threshold, that is, it meets the single judgment condition, it means that the production process of sodium hypochlorite produced by the anode is abnormal. If any one or both of these two indicators meet the single judgment condition, it is necessary to respond in time and send a process adjustment signal to adjust the electrolysis process to ensure product quality and production efficiency. If neither of these two indicators meets the single judgment condition, it is necessary to further verify the sodium chloride concentration in the electrolytic cell 6, that is, send a verification signal to determine whether it can support the continuous production of sodium hypochlorite. If any one of the real-time middle sodium chloride concentration and the cathode bubble generation does not meet the single judgment condition (that is, there is a process adjustment signal that is not within the normal range), the electrolytic cell 6 is further verified. The verification signal is sent to determine whether it can support the continuous production of sodium hypochlorite. , the number of items is greater than 0), the electrolysis process is judged to be abnormal, and a first-class process adjustment signal is issued to change the flow opening; if the real-time middle sodium chloride concentration and the cathode bubble generation do not meet the single judgment condition (that is, both are within the normal range, the number of items is equal to 0), a verification signal is issued, and monitoring is continued for further judgment; based on the verification signal, the absolute value of the sodium chloride concentration difference between the anode area and the cathode area is obtained, and the absolute value of the sodium chloride concentration difference reflects whether the sodium chloride concentrations in the anode and cathode areas of the electrolytic cell are in a balanced state. If the difference is too large, it indicates that there is a large difference in electrolyte concentration between the two areas, and the real-time middle sodium chloride concentration obtained in the middle area has no reference value, that is, it cannot be used as a key indicator for judging the stability of the electrolysis process, and the second-class process adjustment signal is issued. If the difference is within the allowable range, it indicates that there is no large difference in electrolyte concentration between the two areas, and the real-time middle sodium chloride concentration obtained in the middle area can accurately reflect the sodium chloride concentration in the electrolytic cell 6; through multiple judgments in the process, the intelligent device can ensure the continuity and stability of the electrolysis process, optimize the production process, and improve the production efficiency and quality of sodium hypochlorite.

[0119] Specifically, the embodiment of the present invention accurately monitors the key parameters in the electrolysis process and makes timely adjustments based on these parameters. By monitoring the real-time middle sodium chloride concentration and the generation of cathode bubbles, the sodium chloride concentration in the electrolytic cell can be balanced to ensure the output and quality of sodium hypochlorite. Abnormal conditions in the production process can be discovered in time and corresponding adjustment measures can be taken. By issuing a process adjustment signal, the flow opening can be dynamically adjusted to optimize the electrolysis process and improve production efficiency. Decisions can be made automatically based on monitoring data, reducing manual intervention and improving the level of automation. Changes in the electrolysis process can be responded to in real time, and adjustments can be made quickly to reduce the time of production interruptions. By controlling the bubble distribution and sodium chloride concentration, the safety risks that may be caused by the instability of the electrolysis process are reduced. Based on the analysis of real-time data, the production process can be continuously optimized to improve the scientificity and accuracy of production. Through multiple determinations and adjustments, the continuity and stability of the electrolysis process can be ensured, and production fluctuations can be reduced.

[0120] Specifically, in this embodiment, the adjustment module includes: a first receiving unit and a second receiving unit;

[0121] The first receiving unit is used to receive the preliminary adjustment signal and adjust the preset initial stirring rate accordingly according to the preliminary adjustment signal to adjust it to the actual stirring rate;

[0122] The second receiving unit is used to receive a process adjustment signal and adjust the initial flow opening to an actual flow opening according to the process adjustment signal;

[0123] Wherein, based on different types of preliminary adjustment signals, different adjustment modes for the initial stirring rate are determined; based on different types of process adjustment signals, different adjustment degrees for the initial flow opening are determined.

[0124] In the specific implementation process, after the first receiving unit detects the preliminary adjustment signal, it will determine whether to increase or decrease the initial stirring rate according to the type of the preliminary adjustment signal (a type I preliminary adjustment signal or a type II preliminary adjustment signal); the specific determination process is: when the actual anode bubble distribution number is greater than or equal to the anode bubble distribution number threshold, a type I preliminary adjustment signal is issued, and the first receiving unit will increase the initial stirring rate to reduce the overflow of chlorine; when the actual anode bubble change rate is greater than or equal to the anode bubble rate threshold, a type II preliminary adjustment signal is issued, and the first receiving unit will reduce the initial stirring rate to avoid the electrolysis process being too intense;

[0125] After the second receiving unit detects the process adjustment signal, it will decide the degree of adjustment to increase the initial flow opening according to the type of process adjustment signal (Type I process adjustment signal or Type II process adjustment signal). The adjustment module receives the process adjustment signal and analyzes its type. Type I process adjustment signal indicates that there is a more serious abnormality in the electrolysis process and a larger adjustment range is required; while Type II process adjustment signal indicates that there is a slight abnormality in the electrolysis process and fine-tuning is required. According to the signal type, the second receiving unit formulates a corresponding adjustment strategy. For Type I process adjustment signal, the initial flow opening needs to be greatly increased to quickly correct the abnormality in the electrolysis process; for Type II process adjustment signal, the initial flow opening needs to be fine-tuned to maintain the stability of the electrolysis process.

[0126] Specifically, the embodiment of the present invention dynamically adjusts the stirring rate and the flow opening according to the real-time data in the electrolysis process to adapt to the changes in the electrolytic cell. According to different adjustment signal types, the adjustment range of the stirring rate and the flow opening can be accurately controlled to ensure the accurate control of the electrolysis process. By timely adjusting the stirring rate and the flow opening, the stability of the electrolysis process can be effectively maintained and the production fluctuation can be reduced. By adjusting the stirring rate and the flow opening, the system can optimize the electrolysis efficiency and increase the output of sodium hypochlorite. By increasing the stirring rate, the overflow of chlorine is reduced, the utilization rate of raw materials is improved, and environmental pollution is reduced.

[0127] See also Figure 4 As shown, it is a structural schematic diagram of a correction module in an intelligent device based on electrolytic reaction integrated sodium hypochlorite, wherein the correction module includes: a monitoring unit, a correction judgment unit and a correction control unit;

[0128] The monitoring unit is used to monitor the adjustment result of the adjustment module in real time, and integrate the adjustment change degree within the monitoring period and the final adjustment result corresponding to the end node of the monitoring period;

[0129] The correction judgment unit is used to determine whether to make a corresponding correction to the initial control current according to the adjustment change degree and the final adjustment result;

[0130] The correction control unit is used to perform correction according to the judgment result of the correction judgment unit to obtain the actual control current.

[0131] The correction judgment unit includes: a change determination subunit, a result determination subunit and a correction determination subunit;

[0132] The result determination unit is used to make a judgment on the adjustment operation according to the final adjustment result to determine whether the adjustment operation is qualified at one time;

[0133] The change determination subunit determines whether the adjustment operation is qualified for a second time based on the adjustment operation being qualified for a first time and according to the adjustment change degree combined with a preset standard change degree;

[0134] The correction determination subunit determines to start the correction of the initial control current when the first determination result is a first failure, and determines to start the correction of the initial control current when the second determination result is a second failure.

[0135] In the specific implementation process, the degree of adjustment change within the monitoring time refers to the amplitude and frequency of adjustments made by the adjustment module to the flow opening of the flow control valve 2 or the stirring rate of the stirring component within a certain time range, reflecting the dynamic adjustment of the electrolysis process, including the amplitude of the adjustment (i.e., the increase or decrease in the flow opening or the stirring rate) and the frequency of the adjustment (i.e., how many times the adjustment was made within the monitoring time). The final adjustment result corresponding to the end node of the monitoring time refers to the result of the last adjustment made by the adjustment module to the flow opening of the flow control valve or the stirring rate of the stirring component at the end of the monitoring time. This result reflects the final state of the electrolysis process after adjustment within the monitoring time.

[0136] The process of determining whether to make corresponding corrections to the initial control current according to the adjustment change degree and the final adjustment result is as follows: the correction judgment unit will judge whether the initial control current needs to be corrected according to the adjustment change degree and the final adjustment result; if the adjustment change degree and the final adjustment result show that the electrolysis process is still unstable or abnormal, the correction judgment unit will determine that the initial control current needs to be corrected; if the adjustment change degree and the final adjustment result show that the electrolysis process has stabilized, the initial control current is maintained unchanged; if the adjustment change degree and the final adjustment result show that the electrolysis process is still unstable or abnormal, the initial control current is corrected to correct the abnormality in the electrolysis process;

[0137] The result determination unit makes a judgment on the adjustment operation according to the final adjustment result. If the final adjustment result shows that the electrolysis process has stabilized, the result determination unit determines that the adjustment operation is qualified once. If the final adjustment result shows that the electrolysis process is still unstable or abnormal, the result determination unit may determine that the adjustment operation is unqualified once. The change determination subunit determines whether the adjustment operation is qualified twice based on the qualified adjustment operation and the adjustment change degree combined with the preset standard change degree. If the adjustment change degree matches the preset standard change degree, the change determination subunit may determine that the adjustment operation is qualified twice. If the adjustment change degree does not match the preset standard change degree, the change determination subunit may determine that the adjustment operation is unqualified twice.

[0138] For example: the process of correcting the initial control current according to the preliminary adjustment result includes: assuming that the initial control current is set to 10A, which is used to control the reaction rate in the electrolytic cell, the monitoring unit starts to monitor the adjustment result of the initial stirring rate by the adjustment module in real time, including recording the degree of change of the adjustment of the initial stirring rate by the first receiving unit within the monitoring time (for example, 10 minutes) (for example, it was adjusted 5 times, and the amplitude of each adjustment was within ±10%). At the end of the monitoring time, the monitoring unit also records the final adjustment result (the anode bubble generation situation is still abnormal or qualified). The result determination subunit determines whether the adjustment operation is qualified once according to the final adjustment result. If the final adjustment result shows that the electrolysis process is still unstable (the anode bubble generation situation is still abnormal), it is judged to be unqualified. Since the first judgment result is unqualified, the correction determination subunit determines that it is necessary to start a correction of the initial control current. The specific method of correction is to adjust the initial control current according to a certain proportion (for example, reduce it by 10%), or calculate a new control current according to a certain algorithm (such as PID control algorithm). The correction control unit corrects the initial control current according to the judgment result of the correction determination subunit to obtain a new actual control current. If the adjustment operation is qualified once, the change determination subunit further determines the adjustment operation, and determines whether the adjustment operation is qualified twice according to the adjustment change degree combined with the preset standard change degree; the change determination subunit determines whether the adjustment operation is qualified twice according to the adjustment change degree (for example, 7 adjustments are made, and the amplitude of each adjustment is within ±5%) and the preset standard change degree (for example, the expected number of adjustments does not exceed 5 times, and the amplitude of each adjustment does not exceed ±3%). If the adjustment change degree does not match the preset standard change degree (for example, the number of adjustments is too many or the adjustment amplitude is too large), the change determination subunit determines that the adjustment operation is unqualified twice. The correction determination subunit determines that it is necessary to start a correction of the initial control current based on the secondary judgment result that the secondary judgment result is unqualified. If the adjustment change degree matches the preset standard change degree, the change determination subunit determines that the adjustment operation is qualified twice, that is, the preliminary adjustment result is qualified and no correction is required.

[0139] Specifically, the embodiment of the present invention can more accurately evaluate the adjustment effect by real-time monitoring of the adjustment result of the adjustment module, thereby improving the accuracy of the overall adjustment, and can judge whether the initial control current needs to be corrected according to the adjustment change degree and the final adjustment result, thereby ensuring the stability of the electrolysis process, and can accurately correct the initial control current according to the instruction of the correction judgment unit to optimize the electrolysis process. The automated operation of the correction module reduces manual intervention and improves the automation level of the production line. The control current can be dynamically adjusted according to real-time monitoring data, and the changes in the electrolysis process can be quickly responded to. The production efficiency of sodium hypochlorite can be improved by accurately controlling the current. By maintaining the stability of the electrolysis process, the quality of the sodium hypochlorite product is improved, and the intelligent, precise and efficient electrolytic sodium hypochlorite production process is realized, thereby improving the production efficiency and product quality.

[0140] Specifically, in this embodiment, the final judgment module determines that the actual production target is qualified according to the real-time sodium hypochlorite concentration, or sends an alarm signal. The process includes: if the real-time sodium hypochlorite concentration is within a preset qualified range, the final judgment module will determine that the actual production target is qualified.

[0141] If the real-time sodium hypochlorite concentration is not within the preset qualified range, the final judgment module will issue an alarm signal.

[0142] The calculation compensation parameters and the calculation adjustment parameters described in the present invention have two functions: one is to balance the left and right dimensions of the formula, and the other is to adjust the numerical results. No specific assignment is performed in this embodiment. In addition, the calculation formulas in this embodiment are used to intuitively reflect the adjustment relationship between the numerical values, such as positive correlation and negative correlation. Unless otherwise specified, the parameter values ​​that are not specifically limited to numerical values ​​are all positive.
