Description

Technical Field

[0001] This invention relates to the field of water purification control technology, specifically to an online monitoring method and system for the status of a metal ion generator. Background Technology

[0002] With the improvement of living standards and the advancement of technology, people's pursuit of clean drinking water has also increased. A series of metal ion water generating devices, such as silver ion water generators and copper ion water generators, have emerged as a result. These devices contain metal plates that are electrolyzed; these plates are placed in water to undergo electrolysis, thereby generating ionized water containing metal ions.

[0003] Silver ion water and copper ion water have bactericidal and deodorizing properties, so they are widely used in the medical and industrial hygiene management fields both domestically and internationally.

[0004] The inventors have discovered that existing ion generating devices still have at least the following problems:

[0005] During the water purification process, the metal ion generator cannot adjust the electrolysis efficiency based on the water flow rate to meet the disinfection and sterilization requirements of the water. In addition, the electrolysis efficiency is adjusted only after abnormal silver ion concentration is detected. At this time, the water disinfection is incomplete or the silver ion concentration is too high, which may harm health.

[0006] Therefore, we provide an online monitoring method and system for the status of metal ion generators, which can effectively improve the response time of water disinfection and ensure the pass rate and stability of silver ion electrolytic disinfection process. Summary of the Invention

[0025] As a further aspect of the present invention: in step two, if the self-controlled electrolytic silver ion concentration value NCag is within the preset disinfection concentration range [NCmin, NCmax], a self-controlled qualified signal is generated;

[0026] If the self-controlled electrolytic silver ion concentration value NCag is not within the preset disinfection concentration range [NCmin, NCmax], an auxiliary control signal is generated.

[0027] As a further aspect of the present invention: the current auxiliary module includes a current source compensation unit and a current shunt unit.

On the one hand, the water flow is used to generate electricity to provide electrolysis current, ensuring energy efficiency. On the other hand, the electrolysis current is quickly judged and adjusted based on the water flow, ensuring that the silver ion concentration is stable and qualified during the disinfection and sterilization process. This solves the problem that in the existing disinfection and sterilization devices, the silver ion concentration is adjusted only when it is found to be too high or too low, effectively ensuring the response rate and ensuring the sterilization and disinfection of the water quality.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please see Figure 1 As shown, the present invention is an online monitoring method for the status of a metal ion generator, comprising:

[0060] Step 1: Obtain data on the outlet pipe, inlet pipe, and water treatment pipe body; then obtain the electrolysis voltage and water flow temperature; and calculate the self-controlled electrolysis silver ion concentration value.

[0061] The water outlet pipe data includes the water flow velocity and cross-sectional area of ​​the water outlet pipe.

[0062] The inlet pipe data includes the cross-sectional area of ​​the inlet pipe;

[0063] The water treatment pipe body data includes the volume value of the water treatment pipe body;

[0064] Specifically, the calculation method for the concentration of silver ions in self-controlled electrolysis includes the following steps:

[0065] A1: Obtain the outflow velocity value in the outlet pipe through the flow sensor and mark it as CSL. At the same time, obtain the structural data of the outlet pipe and the inlet pipe, including the cross-sectional area value of the outlet pipe CJs and the cross-sectional area value of the inlet pipe RJs.

[0066] pass The inlet flow velocity value RSL of the inlet pipe is calculated;

[0067] A2: Based on the inlet flow velocity value RSL, through... The power generation value P of the power generation device is calculated; where ρ is the density of water and τ is the power generation efficiency.

[0068] Obtain the electrolysis voltage value Uf, through The electrolysis current value If was calculated.

[0069] A3: Obtain the volume value of the water treatment pipe body and mark it as Vc, based on the outflow velocity value CSL and the cross-sectional area value of the outflow pipe CJs;

[0070] pass The ionization sterilization time value t was calculated.

[0071] A4: Then, the water flow temperature value LT inside the water treatment pipe is obtained through a temperature sensor;

[0072] Then, through The self-controlled electrolytic silver ion concentration value NCag of the electrolysis mechanism was calculated; where ω is the electrochemical equivalent of silver ions, F is the Faraday constant, Ea is the activation energy, and δ is the gas constant 8.314; it should be explained that Ea refers to the minimum energy required to overcome the intermolecular potential barrier in a chemical reaction, at which point the chemical reaction can proceed normally.

[0073] Step 2: Determine whether the concentration of self-controlled electrolyzed silver ions is within the preset disinfection concentration range [NCmin, NCmax], and generate an auxiliary control signal; where NCmin is the minimum disinfection concentration of silver ions and NCmax is the maximum disinfection concentration of silver ions.

[0074] Specifically:

[0075] If the self-controlled electrolytic silver ion concentration value NCag is within the preset disinfection concentration range [NCmin, NCmax], a self-controlled qualified signal is generated.

[0076] If the self-controlled electrolytic silver ion concentration value NCag is not within the preset disinfection concentration range [NCmin, NCmax], an auxiliary control signal is generated.

[0077] Step 3: Based on the auxiliary control signal, the electrolysis current value If is adjusted through the current auxiliary module so that the self-controlled electrolytic silver ion concentration value NCag is within the preset disinfection concentration range;

[0078] The current-assisted module includes a current source compensation unit and a current shunt unit. The current source compensation unit is used to increase the current in the electrolysis mechanism, and the current shunt unit is used to decrease the current in the electrolysis mechanism.

[0079] Specifically, the following steps are included:

[0080] A: If the self-controlled electrolytic silver ion concentration NCag is greater than the maximum disinfection concentration NCmax, it indicates that the self-controlled electrolytic silver ion concentration obtained by the current electrolysis current If may be harmful to human health. It needs to be reduced to bring the self-controlled electrolytic silver ion concentration NCag down to the maximum disinfection concentration NCmax. The current reduction value Ijd is calculated.

[0081] Based on the current reduction value Ijd, through Once the adjustable Rsg in the shunt unit is calculated, the shunt unit circuit is activated, and the resistance value in the shunt unit is adjusted to Rsg. It should be noted that the operating voltage of the shunt unit is the same as the electrolysis voltage in the electrolysis mechanism.

[0082] B: If the self-controlled electrolytic silver ion concentration NCag is less than the minimum silver ion disinfection concentration NCmin, it indicates that the self-controlled electrolytic silver ion concentration obtained by the current electrolysis current If is insufficient to achieve disinfection. It needs to be increased to raise the self-controlled electrolytic silver ion concentration NCag to the minimum silver ion disinfection concentration NCmin. The current rise value Isg is calculated;

[0083] At this time, the current source compensation unit compensates the electrolysis mechanism with current output. The compensation current is the current increase value Isg, which makes the current value of the electrolysis mechanism rise to the minimum disinfection concentration value of silver ions NCmin.

[0084] To ensure the stability of the current in the circuit of the current-assisted module, the operating voltage of the current compensation unit is the same as the electrolysis voltage.

[0085] The system uses sensors to quickly and in real-time acquire the water flow status of the outlet pipe, calculates and determines whether the current for electrolyzing silver ions under the current water flow condition can effectively disinfect and sterilize the water flowing through the water treatment pipe, while ensuring that the silver ion concentration is within a safe range. This allows for timely adjustment of the current of the electrolysis mechanism, keeping the electrolysis current within a safe and stable range. On the one hand, the system uses water flow to generate its own electricity to provide the electrolysis current, ensuring energy efficiency. On the other hand, it quickly judges and adjusts the electrolysis current based on the water flow rate, ensuring that the silver ion concentration remains stable and within acceptable limits during the disinfection and sterilization process.

[0086] This invention solves the problem that existing disinfection and sterilization devices adjust the silver ion concentration only when it is too high or too low, effectively ensuring the response rate while ensuring the sterilization and disinfection of the water.

[0087] Step 4: Obtain the non-zero time period of the outflow velocity value CSL within the monitoring time TIM. At the same time, during the operation, the real-time electrolytic silver ion concentration value NCT within the non-zero time period of the outflow velocity value CSL is obtained in real time through the silver ion sensor. The electrolytic silver ion concentration status performance value HG within the monitoring time TIM is calculated and obtained.

[0088] Specifically, it includes the following steps:

[0089] W41: Construct a plane coordinate system of monitoring time and real-time electrolytic silver ion concentration, where monitoring time is the horizontal axis and real-time electrolytic silver ion concentration is the vertical axis;

[0090] The monitoring time and the corresponding real-time electrolytic silver ion concentration value are incorporated into the plane coordinate system;

[0091] W42: The non-zero time intervals of the effluent flow velocity value CSL are sequentially marked as n, where n is 1, 2, 3...; the duration of each non-zero time interval of the effluent flow velocity value CSL is recorded as the non-zero flow velocity duration ZQ. n Meanwhile, the start and end times of each time period when the outflow velocity value CSL is non-zero are marked on the horizontal coordinate axis.

[0092] Obtain the non-zero duration ZQ of each flow rate segment. n The silver ion concentration change time corresponding to the real-time electrolytic silver ion concentration value NCT is denoted as AG. n Simultaneously, the non-zero time interval values ​​of the effluent flow velocity CSL are obtained and marked as m; through The water flow electrolysis response ratio DXB was calculated.

[0093] W43: Obtain non-zero flow rate duration ZQ n The duration of abnormal silver ion concentration (NCT) that corresponds to the real-time electrolytic silver ion concentration value (NCT) not falling within the preset disinfection concentration range [NCmin, NCmax] is YAG. n ;

[0094] Then through The single-cycle stability ratio (DWB) of water electrolysis was calculated. n ;

[0095] W44: Based on the water flow electrolysis response ratio DXB and the water flow electrolysis single-cycle stability ratio DWB n ,pass The state performance value of electrolytic silver ion concentration HG was calculated; where α is the preset response proportionality coefficient and β is the preset temperature proportionality coefficient. Both α and β are greater than zero, with α being 0.642 and β being 0.358.

[0096] Step 5: Compare the electrolytic silver ion concentration state performance value HG with the electrolytic silver ion concentration state performance threshold HGyz, and generate an early warning signal;

[0097] Specifically:

[0098] If the electrolytic silver ion concentration state performance value HG is greater than or equal to the electrolytic silver ion concentration state performance threshold HGyz, a stable signal is generated. At this time, it indicates that during the working process within the monitoring time TIM, the electrolytic silver ion concentration is in a safe, stable and effective state, the silver ion electrolysis concentration has good stability, can meet the requirements of disinfection and sterilization and will not cause toxic effects on the human body.

[0099] If the electrolytic silver ion concentration status value HG is less than the electrolytic silver ion concentration status value threshold HGyz, an early warning signal is generated. This indicates that the electrolytic silver ion reaction may not be timely during the water flow process. On the other hand, it indicates that the electrolytic silver ion concentration is unstable and abnormal. This may be due to consumables or other problems in the electrolysis mechanism, and maintenance is required.

[0100] By plotting the usage process of the device and the changes in silver ion concentration during the monitoring period, the system's response status and silver ion concentration changes during the monitoring period are analyzed and judged to determine whether they are qualified. This enables the device's stability to be judged and warnings to be issued during the monitoring period, thus ensuring the stability of the device's disinfection and sterilization process during silver ion electrolysis.

An online monitoring system for the status of a metal ion generator, characterized in that, The system is used to perform any one of the monitoring methods described in claims 1-9 above, including: Data acquisition module: used to acquire data from the outlet pipe, inlet pipe and water treatment pipe body, then acquire electrolysis voltage and water flow temperature, and calculate the self-controlled electrolysis silver ion concentration value; Data processing module: used to determine whether the concentration of self-controlled electrolytic silver ions is within the preset disinfection concentration range [NCmin, NCmax], and to generate auxiliary control signals; Current-assisted module: Based on the auxiliary control signal, the electrolysis current value If is adjusted through the current-assisted module so that the self-controlled electrolytic silver ion concentration value NCag is within the preset disinfection concentration range; Monitoring module: Used to acquire the non-zero time period of the effluent flow velocity value CSL within the monitoring time TIM. At the same time, during the operation, the real-time electrolytic silver ion concentration value NCT is acquired in real time during the non-zero time period of the effluent flow velocity value CSL through the silver ion sensor, and the electrolytic silver ion concentration status performance value HG within the monitoring time TIM is calculated and obtained. Early warning module: compares the electrolytic silver ion concentration state performance value HG with the electrolytic silver ion concentration state performance threshold HGyz, and generates an early warning signal.
