The present invention relates to a locating system of oxidation / reduction potential of electrolysis water and a constant output method of calibration and compensation of the locating system.

Typically, in testing alkaline reduced water produced by electrolyzed water, for example beverages, when the reduction potential is in the range of between -200 mv and -400 mv, the alkaline reduced water has a good anti-oxidation effect. oxidation effect). For industrial scrubbers, when the reduction potential is in the range between -800 mv and -1000 mv, the alkaline reduced water has a good non-oxidizing and waterproofing effect. On the other hand, when the oxidation potential is about + 750mv, the weak acid oxide water can be used in cosmetics, and when the oxidation potential is in the range of + 960mv to + 1200mv, the strong acid oxide water is sterilization. Available).

Electrolyzed water generators on the market can be used to manually test the oxidation / reduction potential of electrolyzed water by a testing instrument over a period of time. However, since the electrolyzed water generator cannot be used to automatically detect, display and compensate for the oxidation / reduction potential of electrolyzed water, the user may not immediately know whether the oxidation / reduction potential of the electrolyzed water used daily satisfies the criterion. In addition, impurities contained in the water or deposited calcium tend to block the sensor mounted on the testing apparatus, causing errors in the measurement results.

It is an object of the present invention that, when water is electrolyzed, the walls of the cathode tube absorb cations (such as calcium ions), causing calcium to precipitate on the walls of the cathode tube for a predetermined period, thereby causing electrolytic baths during the electrolytic reaction. Since the internal impedance is increased, and thus the current density is reduced, the oxidation / reduction potential of the electrolyzed water is gradually reduced to solve the problem of reaching the original potential.

Accordingly, it is an object of the present invention to provide a locating system of oxidation / reduction potential of electrolyzed water and a constant output method of calibration and compensation of this locating system in order to solve the above-mentioned problem.

According to the first object of the present invention, the water flow controller can control the flow rate of the input water (input water) to obtain a constant electrolysis time.

According to a second object of the invention, the PH value detector detects the PH value in water and the TDS test detects the total solid quantity in the water. The data is then sent to a CPU that compares the oxidation / reduction potential of the actual electrolyzed water with the oxidation / reduction potential indicated by the liquid crystal display to calibrate the upper and lower limits.

According to a third object of the invention, the ideal section of the oxidation / reduction potential is characterized by the oxidation / reduction potential indicated by the liquid crystal display to perform step control according to the relative electrolytic current of the ideal section to obtain a step selection of the oxidation / reduction potential. Is selected according to.

According to the fourth object of the present invention, the user can select an ideal section according to the oxidation / reduction potential displayed by the liquid crystal display, and the circuit control system is adapted to maintain a constant current to maintain the oxidation / reduction potential of the ideal section. The voltage can be adjusted according to the relative current of the ideal section.

According to the fifth object of the present invention, when the resistance in the electrolytic bath is increased to the upper limit and the regulated voltage is also increased to the upper limit, the liquid crystal display reminds the user to clean the electrolytic bath to reduce the resistance of the electrolytic bath. Critical oxidation / reduction potentials can be shown to reduce.

According to the present invention, there is provided a constant output method of calibration and compensation of a locating system of oxidation / reduction potential of electrolyzed water,

And adjusting the voltage of the electrolytic bath so as to accurately control the electrolytic current of the electrolytic bath so that the electrolytic current of the electrolytic bath is maintained at a constant value.

Hereinafter, with reference to the accompanying drawings will be described in more detail the other benefits and advantages of the present invention.

Experimental results show that when the electrolytic bath has a fixed structure (such as the material of the electrode, the type of diaphragm, the relative area and the distance between the anode and the cathode), the oxidation / reduction potential of the electrolyzed water The primary factors that affect are:

1. electrolysis time (flow rate of introduced water);

2. electrolytic current (current density); And

3. Type of electrolyte (rate and concentration of anion and cation)

It was found to include.

1 and 2, FIG. 1 is a coordinate of experimental data of oxidation / reduction potential of electrolyzed water versus electrolysis time, and FIG. 2 is experimental data of oxidation / reduction potential of electrolyzed water versus flow rate of injected water. Coordinate graph of. In this way, the flow rate of the introduced water is reduced when the electrolysis time is increased. As shown in Fig. 1, when the electrolysis time is increased, the oxidation potential of the oxidized water obtained by the anode is gradually increased. For example, the oxidation potential of the oxidized water is expressed as positive values and increases from + 200mv to + 1200mv. In addition, when the electrolysis time is increased, the reduction potential of the reduced water obtained by the negative electrode gradually decreases. For example, the reduction potential of the reduced water is represented by negative values and is reduced from -200mv to -800mv. Thus, when the oxidation potential of the oxidized water is increased, the oxidized water has a stronger oxidation capacity, and when the reduced potential of the reduced water is reduced, the reduced water has a stronger reducing capacity.

Referring to FIG. 3, FIG. 3 is a coordinate graph of experimental data of oxidation / reduction potential versus electrolytic current. In this way, when the electrolytic current (current density) is increased, the oxidation potential of the oxidation water obtained by the anode is gradually increased. For example, the oxidation potential of oxidized water is expressed as positive values and increased from + 200mv to + 1200mv. In addition, when the electrolytic current increases, the reduction potential of the reduced water obtained by the negative electrode gradually decreases. For example, the reduction potential of the reduced water is represented by negative values and is reduced from -200mv to -800mv. Therefore, when the oxidation potential of the oxidation water is increased, the oxidation water has a stronger oxidation capacity, and when the reduction potential of the reduced water is reduced, the reduced water has a stronger reduction capacity.

Referring to FIG. 4, FIG. 4 is a coordinate graph of experimental data of the ratio of the oxidation / reduction potential of electrolyzed water to the ratio of anions and cations (type of electrolyte). In this way, when the proportion of cations (such as calcium, magnesium, sodium, calories, etc.) contained in the electrolyte is increased, the reduction potential of the reduced water obtained by the negative electrode gradually decreases. Therefore, when the reduction potential of the reducing water is reduced, the reducing water has a stronger reducing capacity. Also, when the proportion of anions (such as oxalic acid, carbonic acid, phosphoric acid, etc.) contained in the electrolyte is increased, the oxidation potential of the oxidized water obtained by the anode is gradually increased. Therefore, when the oxidation potential of the oxidation water is increased, the oxidation water has a stronger oxidation capacity.

Referring to FIG. 5, FIG. 5 is a coordinate graph of experimental data of oxidation / reduction potential of electrolyzed water versus concentrations of anions and cations (type of electrolyte). In this way, when the concentration of anions and cations contained in the electrolyte is increased, the reduction potential of the reduced water obtained by the negative electrode is gradually reduced. Therefore, when the reduction potential of the reducing water is reduced, the reducing water has a stronger reducing capacity. In addition, when the concentration of anions and cations contained in the electrolyte is increased, the oxidation potential of the oxidized water obtained by the anode is gradually increased. Therefore, when the oxidation potential of the oxidation water is increased, the oxidation water has a stronger oxidation capacity.

Depending on the electrolysis time (flow rate of water introduced), the electrolytic current (current density) and the type of electrolyte (proportion and concentration of anions and cations), the associated experimental data can be used to produce the following coordinate parameters:

1. Electrolysis time (flow rate of introduced water) is 4 liters per minute;

2. Proportion of Anion and Cation:

   Negative rate 50%;

   50% of the amount; And

3. Concentration of Anions and Cations:

   The concentration of anions and cations is 150 ppm.

Referring to FIG. 6, FIG. 6 is a partially enlarged view of FIG. 3, which is a coordinate graph of experimental data of oxidation / reduction potential of electrolyzed water versus electrolytic current, and electrolysis time and type of electrolyte are constant. Depending on the magnitude of the electrolytic current and the relationship of the oxidation / reduction potential (ORP), the ideal section of the oxidation / reduction potential is determined as follows. For example, the oxidation potential of the oxidized water is in the range of + 960mv and + 1200mv, and the reduction potential of the reduced water is in the range of -200mv and -400mv.

Therefore, according to the electrolytic current of the ideal section, the step control is determined as follows. If the electrolytic current of the ideal section is 2A to 8A, the electrolytic current of the ideal section is divided into 5 steps or a plurality of steps between 2A to 8A, resulting in the following step selection of the oxidation / reduction potential of the electrolyzed water: :

ORP (display value)

= ORP (L) + [A (X) -A (L)] * [ORP (H) -ORP (L)] / [A (H) -A (L)], where

ORP (display value) is the actual display value of the liquid crystal display (LDC);

ORP (L) is the measured value of the first-stage oxidation / reduction potential;

ORP (H) is the measured value of the last-stage oxidation / reduction potential;

A (L) is the measured first-stage minimum current value;

A (H) is the last-step minimum current value measured; And

A (X) is the selected current value of the actual section.

For example, when ORP (H) =-400mv, the electrolytic current is 8A (ie A (H) = 8A), and when ORP (L) =-200mv, the electrolytic current is 2A (ie A (L) ) = 2A).

When the third step is selected, A (X) = 6A.

Therefore, ORP (display value)

= ORP (L) + [A (X) -A (L)] * [ORP (H) -ORP (L)] / [A (H) -A (L)]

= -200mv + (6A-2A) * [(-400mv)-(-200mv)] / [8A-2A]

= -200mv + 4A * (-200mv) / 6A

= -200mv + 4A * (-33.3mv / A)

= -200mv + (-133.2mv)

= -333.2mv.

Thus, the oxidation / reduction current is -333.2mv.

The above mentioned experimental data and formulas are then stored in the database of the central processing unit (CPU). By using a detection member (flow meter), a shunt resistance detection circuit, a TDS test (to measure the total solid amount), and a PH value test, the central processing unit can calculate and compare the results. Thereafter, the central processing unit can compare the oxidation / reduction potential value of the actual electrolytic water with the oxidation / reduction potential value displayed by the liquid crystal display, and can calibrate the upper and lower limits.

Referring to FIG. 7, FIG. 7 is a coordinate graph of experimental data of calibration of upper and lower limits of oxidation / reduction potential of actual electrolytic water.

The formula of the oxidation / reduction potential is as follows.

ORP (display value)

= ORP '(L) + [A' (X) -A '(L)] * [ORP' (H) -ORP '(L)] / [A' (H) -A '(L)],

here,

ORP (display value) is the actual display value of the liquid crystal display (LDC);

ORP '(L) is the measured value of the first-stage oxidation / reduction potential and is -220mv;

ORP '(H) is the measured value of the last-stage oxidation / reduction potential and is -480 mv;

A '(L) is the first-step minimum current value measured and is 2A;

A '(H) is the last-step minimum current value measured and is 8A; And

A '(X) is the selected (third step selected) current value of the actual section, which is 6A.

Therefore, ORP (display value)

= ORP '(L) + [A' (X) -A '(L)] * [ORP' (H) -ORP '(L)] / [A' (H) -A '(L)]

= -220mv + (6A-2A) * [(-480mv)-(-200mv)] / [8A-2A]

= -220mv + 4A * (-260mv) / 6A

= -220mv + 4A * (-43.3mv / A)

= -220mv + (-173.2mv)

= -393.2mv.

Thus, the oxidation / reduction potential is -393.2mv.

At this time, the liquid crystal display displays the relationship between the oxidation / reduction potential value of the electrolyzed water and the electrolytic current. Then, according to the displayed oxidation / reduction potential value, an ideal section of the electrolytic current or the relative oxidation / reduction potential value is selected. After the relative electrolytic current of the oxidation / reduction potential of the selected section is set, the detection circuit can detect a change in resistance in the electrolytic bath. Then, by the formula V (voltage) = I (current) * R (resistance), the electrolytic current can be kept constant by adjusting the working voltage for the resistance. Thus, when the resistance in the electrolytic bath is increased, since the operating current is increased, the electrolytic current can be kept constant to accurately control the electrolytic current of the electrolyzed water according to the selected section.

Referring to FIG. 8, the locating system of oxidation / reduction potential of electrolyzed water according to the present invention includes a first central processing unit (CPU1) 10, a second central processing unit (CPU2) 20, a detection member 30, and a main body.

The first central processing unit 10 also includes functions of calculation, comparison, and input and output of signals.

The formula of the oxidation / reduction potential is as follows:

ORP (display value)

= ORP (L) + [A (X) -A (L)] * [ORP (H) -ORP (L)] / [A (H) -A (L)], where:

The detecting member 30 includes a flow meter 31, a TDS test 32 (which measures the total solid amount), a PH value test 33, and a shunt resistor 34.

The flow meter 31 transmits signals to the database of the first central processing unit 10 to detect the flow rate of the introduced water in the electrolytic bath and also to control the flow rate manually or automatically, in order to control the flow rate and the electrolysis time of the introduced water. It is used to

The TDS test 32 detects the total amount of solids of anions and cations in the water prior to electrolysis and sends signals to the database of the first central processing unit 10 which also functions based on the oxidation / reduction potential in the water. Used.

The PH value test 33 is used to detect the PH value in the water prior to electrolysis and send signals to the database of the first central processing unit 10 which also functions based on the oxidation / reduction potential in the water.

The ORP test equipment can detect the oxidation / reduction potential of the electrolyzed water and send signals to the database of the first central processing unit 10 for calibration of the upper and lower limits.

Referring to FIG. 9, the main control circuit 40 includes an alkali and acid control circuit 41, a step control circuit 42, an electrolytic control circuit 43, a current detection and comparison circuit 44, a voltage compensation and comparison circuit. 45, a constant current control circuit 46 (with a gate driver), and a voltage modulation circuit 47.

The electrolytic bath is provided with a shunt resistor 34. The current detection and comparison circuit 44 and the voltage compensation and comparison circuit 45 can drive the gate driver of the voltage modulation circuit 47 and the constant current control circuit 46 to regulate the voltage, so that the output current is constant. Is maintained.

Referring to FIG. 10, a circuit of shunt register 34 is shown, where:

V is the working voltage of the actual electrolyte;

I is the total current through the electrolytic bath;

R is the actual resistance of the electrolytic bath (variable resistance, for example, resistance increases when calcium precipitates in the electrolytic bath); And

R ₁ and R ₂ are shunt resistors connected in series in the electrolytic bath.

In this way, I = I ₁ + I ₂ and V ₁ = I ₁ * R ₁ = V ₂ = I ₂ * R ₂ .

Therefore, when the actual resistance R is increased (the resistance in the electrolytic bath is increased), the total current I is reduced (since the electrolytic current is reduced), so that the current I of the shunt resistors R ₁ , R ₂ is reduced. ₁ , I ₂ ) is reduced. Since each shunt resistor R ₁ , R ₂ is fixed, when the total current I decreases, the operating voltage V also decreases. By the formula V ₁ = I ₁ * R ₁ = V ₂ = I ₂ * R ₂ , the change in the total current I can be detected by the change in V ₁ .

At this time, the current detection and comparison circuit 44, and the voltage compensation and comparison circuit 45 are gate drivers of the voltage modulation circuit 47 and the constant current control circuit 46 to adjust the operating voltage V of the actual electrolyte. Can be driven.

Since each shunt resistor R ₁ , R ₂ is fixed, the currents I ₁ , I ₂ can be kept constant, and the voltage V ₁ can also be kept constant. By the formula I = I ₁ + I ₂ , when the currents I ₁ and I ₂ remain constant, the total current I also remains constant. Thus, the output of the current I can be kept constant.

The voltage modulating circuit 47 of the main control circuit 40 is an interchangeable transform or frequency vibration modulating circuit. Since the voltage modulation circuit 47 of the main circuit control 40 is controlled by the second central processing unit 20 which increases or decreases the voltage to increase or decrease the current, the total current can be kept constant.
