The electrolytic device 200 is a device that electrolyzes an electrolytic solution. The electrolytic bath 90 is a bath that electrolyzes the electrolytic solution. The electrolytic solution is, for example, an aqueous NaCl (sodium chloride) solution. The electrolytic cell 90 generates Cl ₂ (chlorine), NaOH (sodium hydroxide), and H ₂ (hydrogen) by, for example, electrolyzing an aqueous solution of NaCl (sodium chloride). The electrolytic bath 90 may include a plurality of electrolytic cells 91 (electrolytic cells 91-1 to 91-N, where N is an integer of 2 or more). N is 50, for example.

The liquid 70 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. Alkali metals are elements belonging to group 1 of the periodic table of the elements. When the liquid 70 is an aqueous solution of an alkali metal chloride, the liquid 70 is, for example, an aqueous NaCl (sodium chloride) solution. When the liquid 70 is an aqueous solution of an alkali metal hydroxide, the liquid 70 is, for example, a KOH (potassium hydroxide) aqueous solution or a NaOH (sodium hydroxide) aqueous solution.

A liquid 72 is introduced into each of the electrolytic cells 91-1 to 91-N. After passing through the introduction pipe 93, the liquid 72 may be introduced into each of the electrolytic cells 91-1 to 91-N. The liquid 72 is an aqueous solution of alkali metal hydroxide. The liquid 72 is, for example, NaOH (sodium hydroxide) aqueous solution. When liquid 70 is an aqueous solution of an alkali metal hydroxide, liquid 72 is an aqueous solution of the same alkali metal hydroxide (eg, KOH).

In this example, the lead-out tube 94 and the lead-out tube 95 are connected to the electrolytic cells 91-1 to 91-N, respectively. A liquid 76 and a gas 78 (described later) are drawn out from each of the electrolytic cells 91-1 to 91-N. The liquid 76 and the gas 78 (described later) may be led out of the electrolytic device 200 after passing through the outlet tube 95 . Liquid 76 is an aqueous solution of an alkali metal hydroxide. When liquid 72 is NaOH (sodium hydroxide) aqueous solution, liquid 76 is NaOH (sodium hydroxide) aqueous solution. Gas 78 (described below) may be H ₂ (hydrogen).

The liquid 74 and the gas 77 (described later) may be led out of the electrolytic device 200 after passing through the outlet tube 94 . The liquid 74 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. If the liquid 70 is an aqueous NaCl (sodium chloride) solution, the liquid 74 is an aqueous NaCl (sodium chloride) solution. When the liquid 70 is a KOH (potassium hydroxide) aqueous solution, the liquid 74 is a KOH (potassium hydroxide) aqueous solution. If the liquid 70 is an aqueous NaCl (sodium chloride) solution, the gas 77 (described below) is Cl ₂ (chlorine). If the liquid 74 is a KOH (potassium hydroxide) aqueous solution, the gas 77 (described later) is O ₂ (oxygen).

In this example, one electrolytic cell 91 has an anode compartment 79 , an anode 80 , a cathode compartment 98 , a cathode 82 and an ion exchange membrane 84 . Anode chamber 79 and cathode chamber 98 are provided inside electrolytic cell 91 . The anode chamber 79 and cathode chamber 98 are separated by an ion exchange membrane 84 . An anode 80 is arranged in the anode chamber 79 . A cathode 82 is arranged in the cathode chamber 98 .

An introduction pipe 92 and a discharge pipe 94 are connected to the anode chamber 79 . An introduction pipe 93 and an extraction pipe 95 are connected to the cathode chamber 98 . A liquid 70 is introduced into the anode chamber 79 . A liquid 72 is introduced into the cathode chamber 98 .

The ion-exchange membrane 84 is a membrane-like substance that blocks the passage of ions having the same sign as the ions arranged on the ion-exchange membrane 84 and allows only the ions having the opposite sign to pass through. In this example, the ion exchange membrane 84 is a membrane that allows passage of Na ⁺ (sodium ions) and blocks passage of Cl ⁻ (chloride ions).

Anode 80 and cathode 82 may be maintained at predetermined positive and negative potentials, respectively. Liquid 70 introduced into anode chamber 79 and liquid 72 introduced into cathode chamber 98 are electrolyzed by the potential difference between anode 80 and cathode 82 . At the anode 80 the following chemical reactions take place.
[Chemical Formula 1]
2Cl ⁻ →Cl ₂ +2e ⁻

When the liquid 70 is an NaCl (sodium chloride) aqueous solution, NaCl (sodium chloride) is ionized into Na ⁺ (sodium ions) and Cl ⁻ (chloride ions). At the anode 80, Cl ₂ (chlorine) gas is generated by the chemical reaction shown in Chemical Formula 1. Gas 77 (the Cl ₂ (chlorine) gas) and liquid 74 may be drawn from the anode chamber 79 . Na ⁺ (sodium ions) move from the anode chamber 79 to the cathode chamber 98 after passing through the ion exchange membrane 84 due to the attractive force from the cathode 82 .

The liquid 73 may stay in the anode chamber 79 . The liquid 73 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. In this example, the liquid 73 is an aqueous NaCl (sodium chloride) solution. The Na ⁺ (sodium ion) and Cl ⁻ (chloride ion) concentrations of liquid 73 may be less than the Na ⁺ (sodium ion) and Cl ⁻ (chloride ion) concentrations of liquid 70 .

At the cathode 82 the following chemical reactions take place.
[Chemical Formula 2]
2H ₂ O+2e ⁻ →H ₂ +2OH ⁻

When the liquid 72 is a NaOH (sodium hydroxide) aqueous solution, NaOH (sodium hydroxide) is ionized into Na ⁺ (sodium ions) and OH ^- (hydroxide ions). At the cathode 82, H ₂ (hydrogen) gas and OH ⁻ (hydroxide ions) are produced by the chemical reaction represented by Chemical Formula 2. A gas 78 (such H ₂ (hydrogen) gas) and a liquid 76 may be drawn from the cathode chamber 98 .

The liquid 75 may stay in the cathode chamber 98 . The liquid 75 is an aqueous solution of alkali metal hydroxide. In this example, the liquid 75 is an aqueous NaOH (sodium hydroxide) solution. In this example, the cathode chamber 98 contains a liquid 75 in which OH ⁻ (hydroxide ions) produced by the chemical reaction represented by Chemical Formula 2 and Na ⁺ (sodium ions) transferred from the anode chamber 79 are dissolved. staying.

FIG. 3 is an enlarged view of the vicinity of the ion exchange membrane 84 in the electrolytic cell 91 shown in FIG. Anion groups 86 are immobilized on the ion exchange membrane 84 of this example. Since anions are repelled by the anion groups 86 , they are less likely to pass through the ion exchange membrane 84 . In this example, the anion is Cl ⁻ (chloride ion). The cations 71 are not repelled by the anionic groups 86 and thus can pass through the ion exchange membrane 84 . If the liquid 70 (see FIG. 2) is an aqueous NaCl (sodium chloride) solution, the cations 71 are Na ⁺ (sodium ions).

FIG. 4 is a diagram showing an example of a block diagram of the analysis system 100 according to one embodiment of the present invention. Analysis system 100 includes terminal 10 and server 20 . The terminal 10 has an element acquisition unit 12 . The server 20 has a receiver 22 and a state analyzer 24 . The state analysis unit 24 is, for example, a CPU (Central Processing Unit). The server 20 may be installed with an analysis program for executing an analysis method described later, or may be installed with an analysis program for causing the server 20 to function as the analysis system 100 .

The analysis system 100 may include an information terminal 30. The information terminal 30 may have a display section 32 . The information terminal 30 may be a stationary computer terminal or a tablet computer. When the information terminal 30 is a tablet computer, the display section 32 may be a monitor of the tablet computer.

The information terminal 30 and the terminal 10 may communicate by wire 99, or by short-range wireless communication such as WiFi (registered trademark) and Bluetooth (registered trademark). The wire 99 is, for example, a USB cable or the like. In this example, the information terminal 30 has a first transmitter 14 .

The electrolytic cell 90 and the server 20 may be arranged at different positions. Different locations may refer to different geographic locations. The server 20 is installed, for example, in city A in Japan. When the server 20 is installed in a Japanese city A, the electrolyzer 90 may be installed in a Japanese city B different from the city A, or may be installed in a foreign country other than Japan. The position where the server 20 is arranged is assumed to be position Sa. The position where the electrolytic bath 90 is arranged is defined as position Sb.

The electrolytic cell 90, the terminal 10 and the information terminal 30 may be arranged at the same position. The same location may refer to the same geographical location. Terminal 10 and information terminal 30 may be located at position Sb. When electrolytic cell 90 is installed in a predetermined factory, electrolytic cell 90, terminal 10 and information terminal 30 may be used by the same user in the predetermined factory.

The element acquisition unit 12 acquires the amount of elements contained in the object 110 in the electrolytic bath 90 (see FIG. 1). The terminal 10 is, for example, a portable fluorescent X-ray analysis terminal. If the terminal 10 is a portable X-ray fluorescence analysis terminal, the terminal 10 irradiates an object 110 with X-rays 112 . The X-rays 112 irradiated to the object 110 cause inner-shell electrons in elements contained in the object 110 to be emitted out of the shell. When the electrons emitted out of the shell fall into the inner shell, the object 110 emits X-rays 114 with energy peculiar to the element. If the terminal 10 is a portable X-ray fluorescence analysis terminal, the element acquisition unit 12 acquires the amount of the element by measuring the intensity of the emitted X-rays 114 . The intensity of the X-rays 114 may refer to the number of counts of the X-rays 114 obtained by the element obtaining unit 12 per unit time. The stronger the intensity of the X-rays 114, the greater the amount of the element acquired by the element acquiring unit 12. FIG.

The object 110 may be the ion exchange membrane 84 (see FIG. 2), the anode 80 (see FIG. 2), or the cathode 82 (see FIG. 2). Object 110 may be ion exchange membrane 84 as installed in electrolytic cell 90 , anode 80 , or cathode 82 . When the terminal 10 is a portable X-ray fluorescence analysis terminal, the element acquiring unit 12 can acquire the amount of elements contained in the target object 110 as it is installed in the electrolytic cell 90 .

The element acquisition unit 12 may further acquire the types of elements contained in the target object 110 . When the object 110 is irradiated with the X-rays 112, the energy of the X-rays 114 emitted from the object 110 depends on the type of element. Therefore, when the terminal 10 is a portable X-ray fluorescence analysis terminal, the element acquisition unit 12 can acquire the type of element by measuring the energy of the emitted X-rays 114 .

A liquid 70 (see FIG. 1) obtained by subjecting salt water in which raw salt is dissolved to a predetermined treatment is introduced into the electrolytic cell 90 (see FIG. 1). Predetermined treatments include, for example, precipitation of SS (suspended solids) contained in salt water by a clarifier, removal of the SS by a ceramic filter, Ca (calcium), Sr (strontium) contained in salt water by a resin tower, ), removal of at least one of Ba (barium) and Mg (magnesium), and the like. The raw salt may contain I (iodine).

Since the electrolytic cell 90 electrolyzes the liquid 70, the elements introduced in the predetermined treatment of the salt water may accumulate in the ion exchange membrane 84 (see FIG. 2) as the electrolytic cell 90 operates. When the element is accumulated in the ion exchange membrane 84, the ion exchange performance of the ion exchange membrane 84 may be deteriorated.

Anode 80 and cathode 82 are in contact with liquid 73 and liquid 75, respectively. Liquid 73 and liquid 75 are electrolytic solutions. The surfaces of the anode 80 and the cathode 82 may be coated with Ru (ruthenium) or the like in order to prevent the voltage of the electrolytic cell 90 from increasing. If the coating applied to the surface of anode 80 and cathode 82 deteriorates, the voltage between anode 80, ion exchange membrane 84 and cathode 82 tends to rise.

A user of the analysis system 100 can measure the amount of the element contained in at least one of the ion exchange membrane 84, the anode 80 and the cathode 82 by bringing the terminal 10 close to at least one of the ion exchange membrane 84, the anode 80 and the cathode 82. and type. Thereby, the user of the analysis system 100 can obtain the amount of the element without removing at least one of the ion exchange membrane 84 , the anode 80 and the cathode 82 from the electrolytic cell 90 . A user of the analysis system 100 may acquire the amount and type of elements contained in at least one of the ion exchange membrane 84 , the anode 80 and the cathode 82 installed in the electrolytic cell 90 .

FIG. 5 is a diagram showing an example of the acquisition result of the amount and type of elements acquired by the element acquisition unit 12. FIG. In this example, the amount of an element is represented by the intensity of the X-ray 114 (see FIG. 4), and the type of element is represented by the energy at which the X-ray 114 shows a peak. In this example, the x-rays 114 are spectrally distributed. The element acquisition unit 12 may acquire a spectral distribution of the X-rays 114 .

The first transmission unit 14 (see FIG. 4) transmits the amount of the element acquired by the element acquisition unit 12. The first transmission unit 14 may transmit the amount and type of the element acquired by the element acquisition unit 12 . The first transmitter 14 may wirelessly transmit the amount and type of the element. As used herein, wireless refers to communication that does not rely on wires. Wireless may refer to all communications via the Internet, and is not limited to short-range wireless communications such as Wi-Fi (registered trademark) and Bluetooth (registered trademark). The first transmitter 14 may wirelessly transmit the spectral distribution of the X-rays 114 shown in FIG.

The receiving unit 22 (see FIG. 4) receives the amount of the element acquired by the element acquiring unit 12. In this example, the receiver 22 receives the amount of the element transmitted by the first transmitter 14 . The receiving unit 22 may receive the amount and type of element transmitted by the first transmitting unit 14 . The receiving unit 22 may wirelessly receive the amount and type of the element. The receiver 22 may wirelessly receive the spectral distribution of the X-rays 114 transmitted by the first transmitter 14 .

The state analysis unit 24 analyzes the state of the object 110 based on the amount of elements received by the reception unit 22 . When the object 110 is the ion exchange membrane 84 , the state of the object 110 may be the ion exchange performance state of the ion exchange membrane 84 . When the ion exchange performance of the ion exchange membrane 84 deteriorates, the current efficiency of the electrolytic cell 90 may decrease.

The analysis system 100 of this example differs from the analysis system 100 shown in FIG. 10 in that it includes multiple terminals 10 and multiple information terminals 30 .

In this example, the plurality of electrolytic cells 90 are arranged at different positions. In this example, electrolytic bath 90-1 is placed at position Sb1, electrolytic bath 90-2 is placed at position Sb2, and electrolytic bath 90-m is placed at position Sbm. Here, m is an integer of 2 or more.

The positions Sb1 to Sbm may be different geographical positions. The position Sb1 is, for example, a predetermined city in the United States, the position Sb2 is, for example, a predetermined city in Europe, and the position Sbm is, for example, a predetermined city in Australia.

The state analysis unit 24 may analyze the state of one ion exchange membrane 84 based on the amount of the element received by the reception unit 22 and the first relationship R1 stored in the storage unit 25. This allows the user of the analysis system 100 to recognize the state of one ion-exchange membrane 84 compared with the state of other ion-exchange membranes 84 . In this example, since the receiving units 22 receive the amounts of the elements transmitted by the respective first transmitting units 14 in the plurality of information terminals 30, the receiving units 22 are arranged far apart from each other. The quantity of elements of the object 110 in the electrolytic cell 90 can be received, and the state analysis unit 24 can analyze the state of one ion exchange membrane 84 . Therefore, the user of the analysis system 100 can recognize the analysis result Ra without sending samples of the object 110 for analyzing the state from each of the plurality of positions Sb to the position Sa. Calculation of the analysis result Ra by the state analysis unit 24 becomes easier than when samples of the target object 110 are sent from each of the plurality of positions Sb to the position Sa.

Each of the multiple element acquisition units 12 may further acquire identification information for identifying the target object 110 in one electrolytic bath 90 of the multiple electrolytic baths 90 and the target object 110 in the other electrolytic bath 90 . Let this identification information be identification information Id.

The type of the ion-exchange membrane 84 may be a physical quantity that may vary depending on the individual ion-exchange membrane 84, such as the density of the anion groups 86 (see FIG. 3) in the ion-exchange membrane 84, the thickness of the ion-exchange membrane 84, and the like. . The type of ion exchange membrane 84 may be a so-called lot number for each individual. The type of ion exchange membrane 84 may be the type of anionic groups 86 (see FIG. 3).

If the object 110 is the anode 80 and the cathode 82 , the identification information Id may be the number of the frame that holds the anode 80 and the cathode 82 . The frame holds one anode 80 and one cathode 82 in pairs. One ion exchange membrane 84 may be placed between the anode 80 in one frame and the cathode 82 in the other frame. The anode 80 in the one frame, the cathode 82 in the other frame, and the ion exchange membrane 84 may be included in one electrolytic cell 91 (see FIG. 2).

The storage unit 25 may store operating conditions Cd, types and amounts of elements, identification information Id, and position information for each of the plurality of electrolytic cells 90 .

Let the predetermined first state of the object 110 be the first state S1. The first state S1 may be a state in which the target object 110 has reached the end of its life. When the object 110 is the ion exchange membrane 84 (see FIG. 2), the first state S1 may be a state in which it is difficult for the ion exchange membrane 84 to repel anions.

Let the predetermined second state of the object 110 be the second state S2. The second state S2 may be a state in which the target object 110 has reached the end of its life.

FIG. 12 shows analysis results Ra for a plurality of anodes 80. As shown in FIG. In FIG. 12, time refers to the elapsed time from when the anode 80 is started to be used until the state of the anode 80 is analyzed. The elapsed time may be the number of years elapsed. In FIG. 12, the remaining amount refers to the remaining amount of coating material coating the anode 80 . The coating material may be Ru (ruthenium). In FIG. 12, the current analysis result Ra is indicated by a black circle. The analysis result Ra indicated by the white circle may be the past analysis result Ra rather than the current one.

The analysis result Ra shown in FIG. 12 may be displayed on the display unit 32 (see FIG. 10). As a result, the user of one electrolytic cell 90 (see FIG. 11) can compare the state of the anode 80 in one electrolytic cell 90 with the analysis result Ra of the state of the anode 80 in another electrolytic cell 90 (see FIG. 11). can recognize the analysis result Ra.

In some cases, the operation of the electrolytic device 200 is temporarily stopped in order to identify the cause of performance deterioration of the target object 110 . It is preferable that the time for stopping the operation of the electrolytic device 200 be as short as possible. When the terminal 10 is a portable X-ray fluorescence analysis terminal, the user of the electrolysis device 200 can easily identify the cause of performance deterioration of the object 110 without removing the object 110 from the electrolysis device 200, and the object It becomes easier to take measures to recover the performance of 110. Therefore, the time for stopping the operation of the electrolytic device 200 tends to be shortened. A user of the electrolysis device 200 can restore the performance of the object 110 without replacing the object 110 , thus making the loss of the object 110 less likely.

The element acquisition unit 12 (see FIG. 11) may acquire the amount of the element based on the analysis result Ra transmitted by the second transmission unit 27 (see FIG. 11). The element acquisition unit 12 may acquire the amount of the element based on the analysis result Ra transmitted by the second transmission unit 27 and received by the information terminal 30 . Thereby, the element acquiring unit 12 can acquire the amount of the element reflecting the analysis result Ra. The fact that the element acquisition unit 12 acquires the amount of the element reflecting the analysis result Ra means that, for example, the analysis result Ra of one ion exchange membrane 84 is the specific element at one position of the one ion exchange membrane 84 is accumulated, the element acquisition unit 12 acquires the specific element at another position of the ion exchange membrane 84 .

When the state analysis unit 24 analyzes that the state of the object 110 in the electrolytic cell 90 is at least one of the first state S1 to the third state S3, the element acquisition unit 12 performs one electrolysis. The amounts of elements contained in other objects 110 in bath 90 may be obtained. The element acquiring unit 12 (see FIG. 11) may acquire the amount of elements contained in another target object 110 (see FIG. 4) in one electrolytic bath 90 (see FIG. 11).

For example, the second transmitter 27 (see FIG. 11) sets the state of the ion exchange membrane 84 (see FIG. 2) arranged in one electrolytic cell 91-1 (see FIG. 1) in the electrolytic tank 90-1 to the first state. When the analysis result Ra indicating the state S1 is transmitted to the information terminal 30-1, the element acquisition unit 12-1 (see FIG. 11) is placed in the other electrolytic cell 91-2 in the electrolytic bath 90-1. The amount of elements contained in the ion exchange membrane 84 may be obtained. When the ion-exchange membrane 84 arranged in one electrolytic cell 91-1 is in the first state S1, the ion-exchange membrane 84 arranged in the other electrolytic cell 91-2 is higher than when the ion-exchange membrane 84 is not in the first state S1. There is a high probability that the ion exchange membrane 84 is in the first state S1. Therefore, the user of the analysis system 100 can easily recognize the state of the ion exchange membrane 84 arranged in the other electrolytic cell 91-2.

Similarly, the second transmitter 27 (see FIG. 11) is, for example, an anode 80 (see FIG. 2) arranged in one electrolytic cell 91-2 (see FIG. 1) in an electrolytic bath 90-2 (see FIG. 11). is the second state S2 to the information terminal 30-2, the element acquisition unit 12-2 is placed in the other electrolytic cell 91-3 in the electrolytic bath 90-2. The amount of elements contained in the anode 80 may be obtained.

Similarly, the second transmitter 27 (see FIG. 11) is an ion-exchange membrane 84 (see FIG. 2) arranged in one electrolytic cell 91-3 (see FIG. 1) in the electrolytic bath 90-m (see FIG. 11), for example. ) is the third state S3 to the information terminal 30-m, the element acquisition unit 12-m (see FIG. 11) detects other electrolytic cell The amount of element contained in the ion exchange membrane 84 located at 91-1 may be obtained.

In the analysis system 100 of this example, the server 20 further has a state prediction section 26 . The analysis system 100 of this example differs from the analysis system 100 shown in FIG. 11 in this respect. The state prediction unit 26 is, for example, a CPU (Central Processing Unit). The state analysis unit 24 and the state prediction unit 26 may be one CPU.

The element acquisition unit 12 may acquire changes over time in the amounts of elements contained in the object 110 . Elements contained in the liquid 70 (see FIG. 2) or the like may accumulate in the object 110 as the operating time of the electrolytic cell 90 elapses. Thus, the amount of elements contained in object 110 may change over time.

The first transmission unit 14 may transmit changes over time in the amounts of elements acquired by the element acquisition unit 12 . The receiving unit 22 may receive the temporal change in the amount of the element transmitted by the first transmitting unit 14 .

The state predicting unit 26 predicts the target based on the temporal change in the amount of the element received by the receiving unit 22 and the first relationship R1 (see FIG. 6) or the second relationship R21 (see FIG. 7). It may be predicted when the object 110 will be in the first state S1. As described above, the first state S1 may be a state in which the target object 110 has reached the end of its life. When the object 110 is the ion exchange membrane 84 (see FIG. 2), the first state S1 may be a state in which it is difficult for the ion exchange membrane 84 to repel anions.

The state predicting unit 26 predicts that the object 110 in the one electrolytic cell 90 is in the first state based on the temporal change in the amount of the element in the one electrolytic cell 90 and the second relationship R21 in the one electrolytic cell 90. It may be possible to predict when the state will be in S1, or predict when the object 110 in the other electrolytic bath 90 will be in the first state S1.

The state prediction unit 26 predicts when the object 110 will be in the second state S2 based on the temporal change in the amount of the element received by the reception unit 22 and the second relationship R22 (see FIG. 9). good. As described above, the second state S2 may be a state in which the target object 110 has reached the end of its life. When the object 110 is the anode 80 (see FIG. 2) or the cathode 82 (see FIG. 2), the second state S2 is that the amount of coating material coating the surface of the anode 80 or the cathode 82 is a predetermined amount. less than the stated amount.

Voltage CV is also represented by Equation 3 below.

In Formula 3, i may be Ru (ruthenium) and j may be Fe (iron). In Equation 3, α3 and β3 represent the degree of influence of element i (Ru (ruthenium) in this example) on voltage CV. In Equation 3, ε represents the degree of influence of element j (Fe (iron) in this example) on voltage CV. In Equation 3, γ is a constant.

The state predictor 26 may calculate the consumption rate of the coating material coating the surface of the anode 80 or the cathode 82 . The consumption rate may be the amount of change of In _i in Equation 3 per unit time. The state prediction unit 26 may predict when the anode 80 (see FIG. 2) will be in the second state S2 based on the consumption rate of the coating material.

The second relationship R22 may be defined for each piece of identification information Id. The state prediction unit 26 predicts that the object 110 in the one electrolytic bath 90 is in the second state based on the temporal change in the amount of the element in the one electrolytic bath 90 and the second relationship R22 in the one electrolytic bath 90. The timing of S2 may be predicted, and the timing of the object 110 in the other electrolytic bath 90 being in the second state S2 may be predicted.

The state prediction unit 26 predicts when the object 110 will be in the third state S3 based on the temporal change in the amount of the element received by the reception unit 22 and the third relationship R3 (see FIG. 8). good. In the third state S3, when the object 110 is the ion-exchange membrane 84, the ion-exchange membrane 84 has reached the end of its service life and the Cl ⁻ (chloride ions) of the liquid 75 (aqueous solution of alkali metal hydroxide) ) the density may be a predetermined threshold density.

The third relationship R3 may be defined for each piece of identification information Id. The state prediction unit 26 predicts that the object 110 in the one electrolytic cell 90 is in the third state based on the temporal change in the amount of the element in the one electrolytic cell 90 and the third relationship R3 in the one electrolytic cell 90. The timing of S3 may be predicted, and the timing of the object 110 in the other electrolytic bath 90 being in the third state S3 may be predicted.

A countermeasure for recovering the current efficiency CE of the electrolytic cell 90 is defined as a first countermeasure Cm1. For example, when the current efficiency CE is less than a predetermined value, the first countermeasure Cm1 is a countermeasure based on the cause of the current efficiency CE being less than the predetermined value. This is a countermeasure for recovering the current efficiency CE to a predetermined value or more by eliminating the problem.

For example, when an aqueous NaCl (sodium chloride) solution is introduced into the anode chamber 79 and the concentration of NaCl (sodium chloride) in the aqueous solution is not within a predetermined range, the voltage CV exceeds a predetermined value. If this is the cause, the second countermeasure Cm2 is a countermeasure for returning the NaCl (sodium chloride) concentration to a predetermined range.

A countermeasure for recovering the Cl ⁻ (chloride ion) concentration of the liquid 75 is a third countermeasure Cm3. When the Cl ⁻ (chloride ion) concentration of the liquid 75 exceeds a predetermined concentration, the third measure Cm3 is to determine the cause of the Cl ⁻ (chloride ion) concentration exceeding the predetermined concentration. It is a countermeasure based on the above, and is a countermeasure for recovering the Cl ⁻ (chloride ion) concentration of the liquid 75 to a predetermined value or less by eliminating the cause. Restoring the Cl ⁻ (chloride ion) concentration to a predetermined value or less may refer to reducing the Cl ⁻ (chloride ion) concentration to a predetermined value or less.
