Description

Sodium hypochlorite generator capable of monitoring the life and replacement cycle of the electrolytic electrode {Sodium hypochlorite generator capable of monitoring the life and replacement cycle of the electrolytic electrode}

The present invention relates to a sodium hypochlorite generator capable of monitoring the life and replacement cycle of an electrolytic electrode. More specifically, by controlling the concentration of diluted brine to provide stable salinity and maintaining a constant temperature through a temperature control device, sodium hypochlorite at a constant concentration is produced with stable current efficiency regardless of seasonal changes and It relates to a sodium hypochlorite generator capable of monitoring the lifespan and replacement cycle of an electrolytic electrode that predicts the lifespan and gives a notification of replacement.

In general, a device that generates sodium hypochloride (NaOCl) is a device that electrolyzes salt water or seawater to generate sodium hypochlorite, and sodium hypochlorite generated by such a device is sterilized in a water purification plant, sewage treatment plant or swimming pool Not only can it be used for treatment, but it is also used in various fields such as bleaching agent, oxidizing agent, sterilization disinfectant, deodorant, stabilizer of celluloid, organic synthesis, separation and purification of oil and oil industry.

Sodium hypochlorite can be generated by electrolysis of diluted brine. At this time, the diluted brine is dissociated into sodium ion (Na+) and chloride ion (Cl-), and the chloride ion is oxidized at the anode to become chlorine. (Equation ① below), sodium ions are reduced at the cathode to produce sodium (Equation ② below), and the generated sodium reacts with water to form sodium hydroxide (NaOH, caustic soda) and hydrogen (Equation ③ below), Chlorine generated at the anode reacts with the sodium hydroxide to produce sodium hypochlorite (NaOCl) (Equation ④ below).

Cl- → ½Cl2 + e- -------------------- ① Formula

Na+ + e- → Na ------------ ② Formula

Na + H2O → NaOH + ½H2 ------------ ③ Equation

2NaOH + Cl2 → NaOCl + H2 + NaCl + H2O ------------ ④ Equation

The lifespan of electrolytic electrodes of devices that generate sodium hypochlorite using electrolysis are different for each manufacturer, and since there is no exact standard for replacement, consumers have no choice but to follow the manufacturer's claims. Maintenance data based on more objective data is necessary to provide to consumers.

Electrolytic electrode life is generally affected by oxidative corrosion of the anode, and the applied current amount and oxidation reaction have a proportional relationship. Current density is the amount of current applied per surface area of the electrode, and the higher the current density, the lower the lifetime. . Therefore, a graph of lifetime per current density can be obtained through an accelerated test of the electrolytic electrode, and the formula is expressed as “life = constant 1 x (current density) ^{constant 2} ”.

The performance and lifespan of the electrolytic electrode used in electrolysis is determined by the thickness and composition ratio of the noble metal oxide film coated on the surface. It is not known whether it is used, and since the occurrence of abnormalities in performance and lifespan is very slow due to the nature of the electrode, there is room for controversy with the manufacturer in analyzing the cause.

Therefore, there is a need for a new means to provide consumers with accurate information about products and improve convenience by applying a system that predicts the life of electrodes and informs replacement time.

First, with reference to FIG. 1, components of a sodium hypochlorite generator capable of monitoring the lifespan and replacement cycle of an electrolytic electrode according to a preferred embodiment of the present invention will be described in detail.

The water softener 100 may produce soft water by lowering the content of calcium ions and magnesium ions in the inflow water. Hardness 1 is when 1 mg of calcium oxide (CaO) is included in 100 ml of water, and soft water refers to water with a hardness of 10 degrees or less.

Soft water has relatively few dissolved salts, so it can minimize the occurrence of deposits or scale in generating sodium hypochlorite.

The soft water generated in the water softener 100 is discharged to the soft water outlet generated in the water softener, and the soft water outlet is branched into the salt water storage tank inlet pipe and the soft water storage tank inlet pipe, respectively, and the soft water discharged through the soft water outlet is discharged to the brine storage tank and the soft water storage tank. is introduced

The soft water storage tank 200 may store soft water produced through the water softener, and the soft water stored in the soft water storage tank may be discharged to the diluted brine storage tank.

The brine storage tank 300 can produce saturated brine, and includes a soft water inlet, a salt inlet, a storage tank, and a saturated brine outlet.

Since the soft water inlet is connected to the salt water storage tank inlet pipe of the water softener, the softened water softened in the water softener can be introduced.

The salt inlet may introduce salt that can be dissolved in soft water.

In the storage tank, soft water introduced through the soft water inlet and salt introduced through the salt inlet are dissolved for a predetermined time to become saturated brine having a saturation concentration of 26 to 30%, and the resulting saturated brine can be stored.

The saturated brine outlet may discharge the saturated brine stored in the storage tank of the brine storage tank to the diluted brine storage tank.

The saturated brine inlet 420 can flow in the saturated brine stored in the brine storage tank and has a saturated brine inflow blocking valve, so that the saturated brine inlet is opened to allow the saturated brine to flow in through the saturated brine inlet, The inflow of saturated brine through the saturated brine inlet can be blocked by closing the saturated brine inflow blocking valve.

The water level sensor can measure the level of the diluted brine storage tank, and can control the concentration of the diluted brine inside the diluted brine storage tank by interlocking with the soft water inflow shutoff valve at the soft water inlet and the saturated brine inflow shutoff valve at the saturated brine inlet.

The circulation pump circulates the diluted brine inside the diluted brine storage tank so that the diluted brine inside the diluted brine storage tank can have a uniform temperature and uniform concentration.

When the temperature of the diluted brine sensed by the temperature sensor of the heat exchanger is below the set temperature, the temperature of the diluted brine is heated using the heating unit, and when the temperature of the diluted brine sensed by the temperature sensor is higher than the set temperature, the temperature of the diluted brine is cooled using the cooling unit. The temperature of the diluted brine stored inside the diluted brine storage tank can be kept constant at the set temperature.

Hereinafter, an operating method of a sodium hypochlorite generator capable of monitoring the lifespan and replacement cycle of an electrolytic electrode according to a preferred embodiment of the present invention will be described in detail.

First, looking at the principle for predicting the lifespan and replacement cycle of the electrolytic electrode according to the present invention, the lifespan of the electrolytic electrode is generally affected by oxidation corrosion of the anode, and the amount of applied current and the oxidation reaction have a proportional relationship. . The current density is the amount of current applied per surface area of the electrode, and the higher the current density, the lower the lifetime. It can be expressed as a least squares fit. Therefore, a graph of current density extinction life can be obtained through an accelerated test of the electrolytic electrode.

Since the lifetime prediction of the electrolytic electrode is evaluated by the change in voltage, the temperature and salinity of the electrolyte flowing into the electrolytic cell must be constantly controlled. Since water temperature and salinity are factors that change the electrical conductivity and affect voltage change, they must be constantly controlled to predict a higher lifespan of the electrode. Since it is equipped with a device and a water level sensor, the concentration and temperature of the diluted brine can be kept constant.

The same electrode was evaluated for acceleration in 3% saline. The set current densities were 5,000A/m2, 15,000A/m2, and 30,000A/m2, respectively, and the point where the voltage rose by 4V or more compared to the initial voltage value was set as the end point, and the results are shown in Table 1 below.

Current density (A/m2) 5,000 15,000 30,000 Initial voltage value (V) 5.73 10.34 17.75 End voltage value (V) 9.73 14.34 21.75 Acceleration period (minutes) 36,186 6,564 2,066

Based on the results of Table 1, the relationship between current density and time is represented by the least squares method as a log-log value, and as a result, the graph shown in FIG. 6 can be obtained. Prediction by current density using the formula obtained in FIG. 6 The lifetime is shown in Table 2 below.

Current density (A/m2) 600 700 800 900 1000 Expected life (hours) 18,175 14,207 11,477 9,508 8,035

A test was conducted to find out the change in voltage according to temperature, salinity, and current density. , 2.5%, 3.0%, a total of 5 sections, 800A/m2 and 1000A/m2, which are most commonly used in the field, were selected for the current density.

In addition, the array of electrodes is largely divided into a monopolar form in which the anode and cathode face directly and a bipolar form in which current can skip by connecting a neutral plate between the anode and cathode. The major difference between the two is that the monopolar If a current of 20A and a voltage of 5V are applied, the second stage of the bipolar can show the same performance with a current of 10A and a voltage of 10V. In this embodiment, voltage changes were observed with respect to the temperature, salinity, and current density for monopolar, bipolar 2-stage, and bipolar 4-stage.

The above test results are shown in FIG. 7, and based on the results of FIG. 7, the following operating factors could be derived.

1. It was found that the difference in voltage value by salinity becomes larger when the water temperature is lowered below 10 ℃, and considering that the temperature increase △t value in the electrolytic cell is about 20 ℃, the internal temperature of the electrolytic cell is 35 ℃ or higher, chlorate generation increases And since the electrolytic efficiency decreases, the temperature of the influent of the electrolyzer should be controlled in the range of 10 to 15 ° C.

2. For salinity, the voltage difference by temperature was found to be the smallest in the range of 2.5% to 3.0%, and 2.6% to 3.4%, which is the range generally controlled in the field, would be suitable.

3. Regarding the voltage relationship between monopolar and bipolar, when the number of bipolar stages increases by two, the voltage increases by 2.1~2.2 times. Therefore, it is possible to calculate the voltage setting value for predicting the life of the electrode according to the shape of the electrolytic cell.

Based on the above two examples, set values for predicting electrode life as shown in Table 3 were selected.

current density 800A/m2 1000A/m2 Electrolyzer shape monopolar bipolar 2 stage Bipolar 4 stage monopolar bipolar 2 stage Bipolar 4 stage diluted brine temperature 10~15℃ diluted saline concentration 2.6 to 3.4% alarm life expectancy 11,477 hours 8,035 hours electrode replacement
voltage value 5.5V 12.1V 26.6V 5.8V 12.8V 28.1V

The expected life and electrode replacement voltage value for electrode life prediction are stored in the database of the integrated management server module, and inflow water is allowed to flow into the water softener.

Inflow water may flow into the water softener 100, and the inflow water may be tap water supplied from the outside or fresh water including ground water. there is.

The soft water generated in the water softener 100 is discharged through the soft water outlet 110 formed in the water softener 100, and the brine storage tank inlet pipe and the soft water storage tank inlet pipe branched from the soft water outlet 110 respectively in the salt water storage tank ( 300) and the soft water storage tank 200.

The soft water introduced into the brine storage tank 300 together with the salt flowing into the salt inlet 320 of the brine storage tank 300 is saturated and dissolved in the soft water after a predetermined time to generate saturated brine.

The diluted brine storage tank 400 is provided with a water level sensor 430 interlocked with the soft water inflow blocking valve and the saturated brine inflow blocking valve, so that the concentration of diluted brine stored in the diluted brine storage tank 400 can be controlled.

More specifically, assuming that diluted brine is prepared by mixing 70% of soft water and 30% of saturated brine, the soft water inlet shut-off valve is opened to allow soft water to flow into the diluted brine reservoir, and the water level in the diluted brine reservoir rises to 70%. When it is, the soft water inflow shutoff valve is closed to block the inflow of soft water through the soft water inlet, and the saturated brine inflow shutoff valve is opened to allow the saturated brine stored in the brine storage tank to flow into the diluted brine storage tank. When it reaches 100%, the saturated brine inflow shut-off valve is closed to block the inflow of saturated brine.

That is, in conjunction with the water level sensor 430, the soft water inflow blocking valve and the saturated brine inflow blocking valve are sequentially opened and blocked to control the concentration of diluted brine.

In addition, the diluted brine storage tank 400 is provided with a heat exchanger 450 including a cooling unit, a heating unit, and a temperature sensor. When the temperature of the diluted brine sensed by the sensor is higher than the set temperature, the temperature of the diluted brine stored in the diluted brine storage tank can be maintained at the set temperature by cooling the temperature of the diluted brine using the cooling unit.

Diluted brine controlled at a constant water temperature and salinity can flow into the electrolytic cell 500, and the diluted brine introduced into the electrolytic cell dissociates into sodium ion (Na+) and chloride ion (Cl-), and the chloride ion is anode It is oxidized to become chlorine, and sodium ion is reduced to sodium at the cathode.

The produced sodium reacts with water to form sodium hydroxide and hydrogen, and then the chlorine generated at the anode reacts with the sodium hydroxide to produce sodium hypochlorite.

While the electrolysis reaction occurs in the electrolytic cell 500, in order to predict and evaluate the life of the electrolytic electrode, the DC power supply device can supply DC current to the electrolytic electrode and output a voltage according to the DC current. Information is transmitted to the integrated management server module.

When the output voltage is input to the integrated management server 700, the voltage output value of the electrolytic electrode is input to the life expectancy calculator only when the output voltage is maintained for a predetermined time, and the instantaneous voltage change maintained for an extremely short time is judged as noise. so that it is not input to the predicted life calculation unit.

The life expectancy calculation unit compares and calculates the data stored in the database unit with the input voltage output value to predict the lifespan of the electrolytic electrode.

The administrator can set by inputting the operating current density and electrolytic cell type in the integrated management server, and the predicted life calculation unit compares and calculates the accumulated operating time and the expected lifespan setting value of the electrolytic electrode. If the accumulated operating time is greater than the expected life of the electrolytic electrode An accumulation time alarm signal may occur, and when an accumulation time alarm signal occurs, the predicted life calculation unit compares the electrolysis electrode voltage value of the electrolytic cell with the electrode replacement setting voltage value, and if the electrolytic cell voltage value is lower than the electrode replacement setting voltage value, It operates normally, and if the electrolytic cell voltage value is higher than the electrode replacement set voltage value, a voltage abnormality alarm is generated.

If the cumulative operation time is less than the expected life set value by comparing the cumulative operation time and the expected life set value of the electrolytic electrode in the life expectancy calculation unit, the electrolytic cell voltage value and the electrode replacement set voltage value are compared and calculated by the predicted life calculation unit When the voltage value is lower than the electrode replacement set voltage value, normal operation is performed, and when the electrolytic cell voltage value is higher than the electrode replacement set voltage value, an electrode replacement signal is generated so that the electrode can be replaced.

In addition, when a voltage abnormality alarm occurs, the predicted life calculation unit compares the salinity and water temperature of the diluted brine storage tank with the set salinity and water temperature, and when the salinity and water temperature are out of the set value range, the heat exchanger, the soft water inflow shut-off valve, and saturation The salt water inflow shutoff valve is operated to control the salinity and water temperature so that they fall within the set value range, and when the salinity and water temperature meet the set value range, an electrode replacement signal is finally generated so that the electrode can be replaced.
