Description

[Technical Field]

[0001] The present invention relates to a control circuit, and more specifically to a control circuit and control method for a dual electrolytic water parallel connection production apparatus based on O3 and H2O2. [Background technology]

[0002] In the market, electrolyzed purified water produced by double electrolysis is widely used in industries such as semiconductors, pharmaceuticals, laboratories, and power generation. For example, in semiconductor manufacturing, ultrapure water is an important raw material for wafer cleaning and chemical production, as even trace amounts of impurities can affect chip performance. In the pharmaceutical field, high-purity water is essential for the production of injectable drugs and biopharmaceuticals, and in laboratories, ultrapure water is used for precise experiments and analyses. Furthermore, with increasing environmental protection requirements and industrial upgrades, the application prospects for double electrolysis technology in the water treatment field are broad, and market demand is steadily increasing, especially in high-end manufacturing and scientific research fields where water quality requirements are extremely high. In the future, with technological advancements and cost optimization, the technology for producing electrolyzed purified water by double electrolysis is expected to achieve large-scale applications in many more fields.

[0003] However, during the electrolysis process, ion movement and chemical reactions occur, and if the water quality is relatively complex, for example, if the water contains iron rust, hardness exceeding a certain value, or organic matter, the drinking water after electrolysis may have an unpleasant taste, an unpleasant odor, precipitates, and may even cause the water ionizer to shut down. These natural defects of water ionizers make them less acceptable to a wider range of consumers and hinder their widespread adoption worldwide.

[0004] Chinese patent publication number CN105923858A discloses an electrolytic water apparatus comprising an RO membrane and an electrolytic cell, the technical points of which are as follows: the RO membrane is positioned in front of the electrolytic cell having a double water supply structure, the purified water end of the RO membrane is connected to the main water supply end of the electrolytic cell via the electrolytic cell water supply assembly, and the concentrated water end of the RO membrane is connected to the front water supply assembly of the RO membrane, the auxiliary water supply end of the electrolytic cell, and the water supply end of the washing assembly of the washing assembly of the electrolytic cell via the return water assembly, the drain assembly, and the washing assembly, respectively. When producing alkaline electrolyzed water, raw water is purified by the front purification assembly of the RO membrane and the RO membrane, producing pure water and concentrated water. The pure water enters the first water inlet of the electrolytic cell via the electrolytic cell water supply assembly, and the concentrated water enters the second water inlet of the electrolytic cell via the drain assembly. A DC voltage is applied to the electrode plates of the electrolytic cell, where the electrode plate on the first water inlet side of the electrolytic cell is the cathode and the electrode plate on the second water inlet side is the anode. The following electrolysis reaction occurs inside the electrolytic cell. Anode side: 2H2O-4e=O2↑+4H (acidic, oxygen-rich water) Cathode side: 4H2O + 4e = 2H2↑ + 4OH- (alkaline, hydrogen-rich water) Under the action of a DC electric field, some of the mineral ions in the concentrated water (positive ions such as calcium, magnesium, iron, sodium, and zinc) move to the cathode side through the cation membrane, thereby increasing the mineral ions in the pure water on the cathode side to some extent. Other impurities in the concentrated water, such as bacteria, anions, and residual chlorine, are blocked by the high-density cation membrane. However, mineral ions such as calcium and iron in the concentrated water are separated by the RO membrane. These mineral ions easily adhere to the electrodes under electrode reactions, leading to the formation of scale. If a certain amount of scale accumulates, it will affect the electrolysis efficiency.

In this embodiment, the pressure switch module includes a pressure sensor for monitoring the pressure in the pipeline, and a coupler is electrically connected to the pressure sensor to the main control circuit so that it outputs a current cutoff signal to the main control circuit when the pressure increases to a set threshold. The pressure switch module uses a pressure sensor to acquire the pressure in the pipeline, but the pipeline may be bent and blocked, and if the pressure is too high, the electrolytic device can be automatically turned off.

[0027] For example, in this embodiment, the resistance value of R0 is set to 10Ω, and the scale degree threshold T is set to 20%, f min is set to 0.1Hz, f max is set to 10Hz, and the value of k is set to 0.1. When there is little scale, the resistance R X is measured to have a value of 11Ω. The scale degree S=((11-10) / 10)*100%=10%, in this case, S<T, and the polarity reversal frequency is f=f min =0.1Hz. When there is much scale, the resistance value of the resistor R X is measured to be 15Ω, and when the scale degree S=((15-10) / 10)*100%=50%, S=50%>20%, and the polarity reversal frequency f=0.1+0.1×(50-20)=3.1Hz is measured.
