The operation of the present utility model is as follows:

Salt water tank replenishment:

When it is ensured that there is saturated salt solution in the salt solution tank, and the liquid level is higher than the low level of the salt solution tank "LL", the brine pump is automatically started when the liquid level of the brine tank is lower than the high level and low level of the brine tank "HL", and the brine tank is opened The water inlet solenoid valve, the brine tank starts to replenish water. When the liquid level of the brine tank reaches the high level of "HH", the brine pump stops automatically, and the water inlet solenoid valve of the brine tank is closed, and the brine tank stops water replenishment. So cycle.

Forward electrolysis:

(1) Flushing: When the liquid level in the softening water tank and the brine tank are both higher than the low level of "LL" and the liquid level of the acidizing water tank is lower than the high level of "HL", the softening water pump starts to flush the water inlet solenoid valve, the first acidified water outlet solenoid valve, the acidified water flushing and discharging solenoid valve, the first alkaline water outlet solenoid valve, and the alkaline water flushing and discharging solenoid valve are opened, and the electrolytic cell is flushed for 30s;

(2) Electrolysis: After flushing, the solenoid valve for flushing water is closed, the power of the electrolytic tank is turned on, the metering pump is turned on, and the acidified water pipeline starts to detect the pH value and ORP oxidation-reduction potential. When the pH value of the water quality is between 2.0 and 3.0, the ORP After the oxidation-reduction potential > 1100mV, the acidified water flushing discharge solenoid valve and the alkaline water flushing discharge solenoid valve are closed, the acidizing water tank inlet solenoid valve and the alkaline water tank inlet solenoid valve are opened, and positive electrolysis is performed at this time.

Reverse electrolysis:

(1) Flushing: Open the flushing water inlet solenoid valve, the second acidified water outlet solenoid valve, the acidified water flushing and discharging solenoid valve, the second alkaline water outlet solenoid valve, and the alkaline water flushing and discharging solenoid valve, and flush the electrolytic cell for 30s;

(2) Electrolysis: After flushing, turn off the solenoid valve for flushing water, turn on the power of the electrolytic tank, turn on the metering pump, and start to detect the pH value and ORP oxidation-reduction potential of the acidified water pipeline. When the pH of the water quality is between 2.0 and 3.0, ORP oxidation After the reduction potential > 1100mV, the acidified water flushing and discharging solenoid valve and the alkaline water flushing and discharging solenoid valve are closed, the acidizing water tank water inlet solenoid valve and the alkaline water tank water inlet solenoid valve are opened, and positive electrolysis is performed at this time.

Automatic standby:

(1) When the acidification water tank is at the "HH" high level in the water production state, the equipment will automatically enter the standby state.

(2) When the acidification water tank is above the high level and low level of "HL" when it is just started, the equipment will automatically enter the standby state.

Equipment water supply:

The delivery pump is controlled by the "LL" low liquid level of the corresponding water tank, and the delivery pump's own pressure control. When the liquid level of the corresponding water tank is higher than the low level of "LL", the delivery pump starts to supply water; if there is no water at the back end, the pipeline pressure rises and reaches the set value of the pressure difference switch of the delivery pump, and the delivery pump stops automatically; When the back end uses water, the pipeline pressure decreases, and when it is lower than the set value of the differential pressure switch, the pump starts automatically.

Electrolysis reaction in electrolyzer:

By selecting electrodes of different rare metal materials, we can obtain the hydrogen evolution potential and chlorine evolution potential we need, choose the appropriate type of ion exchange membrane, and realize the exchange of Na ⁺ , Cl ^- , H ⁺ through DC low voltage and high current to generate acidic oxidation Potential water and alkaline reduction potential water, the electrolysis reaction equation is as follows:

Anode: 2H ₂ O→4H ⁺ ＋O ₂ ↑＋4e- 2C ^l- →Cl ₂ ↑＋2e-

Cl ₂ (aq)+H ₂ O→HCl+HClO

Cathode: H ₂ O+2e-→1 ^/ 2H ₂ ↑+2OH-

Principle of action:

(1) Many studies at home and abroad have proved that the acidic oxidation potential water has a broad bactericidal spectrum, which can not only kill bacterial propagules and viruses, but also kill various pathogenic microorganisms such as spores. Relevant literature and laboratory sterilization test results show that the acidic oxidation potential water stock solution (without organic matter) can completely kill Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus (including MRSA), Neisseria gonorrhoeae and other bacterial propagules after being acted for 15-30 seconds 30 seconds of action can completely destroy hepatitis B surface antigen (HBsAg) and kill AIDS virus (HIV); 10 minutes of action can kill Candida;

(2) Sterilization mechanism of acidic oxidation potential water:

The low pH value (2.0-3.0) and high ORP value (above +1100mV) of acidic oxidation potential water exceed the living range of microorganisms, and change the potential of microbial cell membranes, resulting in enhanced cell membrane permeability, and the available chlorine in acidic oxidation potential water is very low. It is easy to enter the cytoplasm, hinder the metabolism of microbial enzymes, and the new metabolic activities of using cells are disturbed and terminated, resulting in cell death. The low pH value enhances this synergistic effect and greatly enhances the bactericidal effect.

According to above-mentioned embodiment, just can realize the utility model well.
