Problems solved by technology

[0004] 1) The pollution of the water environment is deteriorating day by day, the treatment process of the existing waterworks is outdated, and the quality of the factory water has been difficult to meet the standard (especially in the case of sudden drinking water sanitation incidents);
[0005] 2) Secondary pollution caused by the water delivery pipe network system;
[0006] 3) Residual chlorine in water interacts with residual organic matter, which may generate new harmful substances that are not in source water (such as strong carcinogen chloroform, etc.)
The advantage of this electrolytic water cup is that it avoids that the pH may exceed 8.5 after water production, but the disadvantage is that the water purification effect is not as good as the former one.
The common problem of the above two electrolytic water cups is that the power consumption of water production is relatively high

Embodiment 1

[0052] Refer to the electrolysis water cup of this embodiment figure 1 , Including a tank 1 with a water filling port and a water pouring port on the top and an electrolysis power supply 4. The inner bottom of the tank 1 is provided with a pair of cathode electrodes 2 and anode electrodes 3. The cathode electrodes 2 and anode electrodes 3 are respectively connected to the positive and negative electrodes of the electrolysis power supply 4 pole. In this embodiment, the electrolytic power supply 4 is a high-level, narrow-pulse-width regulated 30 volt DC pulse power supply, and an alternating pulse power supply can also be used (but the forward voltage is greater than the reverse voltage).

[0053] In this embodiment, a water-permeable membrane 5 is provided between the cathode electrode 2 and the anode electrode 3. The water-permeable membrane 5 is close to the anode electrode 2 and covers the entire surface of the anode electrode 3, that is, the water-permeable membrane 5 covers th...

Embodiment 2

[0073] The electrolyzed water cup of this embodiment is basically the same as that of the first embodiment. The difference from the first embodiment is that the distance δ between the water-permeable membrane 5 and the cathode electrode 2 in this embodiment is 0 mm, that is, the water-permeable membrane 5 is in close contact with the cathode at the same time. Electrode 2 and anode electrode 3. The water-permeable membrane 5 still uses a PVDF ultrafiltration membrane with an average hydrophobic pore size of 0.03 microns and a thickness of 0.1 mm.

[0074] Perform water electrolysis experiments on the electrolyzed water cups of this embodiment and embodiment 1. The source water is city-supplied tap water, ORP=+320mv, pH=7.1, TDS=148mg / L, other experimental conditions are the same as those of embodiment 1, two experiments The results are shown in Table 2:

Embodiment 3

[0082] The electrolyzed water cup of this embodiment is basically the same as the first embodiment, such as figure 2 As shown, the different changes from the first embodiment are: 1) A first through hole 8 is opened on the cathode electrode 2 with a diameter of 1 mm; 2) A water-permeable membrane 5 covers part of the surface of the anode electrode 3 (anode electrode The entire surface facing the cathode electrode 2); 3) The distance δ between the water-permeable membrane 5 and the cathode electrode 2 is 2 mm.

[0083] The electrolysis water cup of this embodiment is subjected to a water electrolysis experiment. In this embodiment, 24 first through holes with a diameter of 1mm are uniformly distributed on the cathode electrode, and the electrolysis time is 20 minutes. Other experimental conditions and detection methods are the same as those of the first embodiment. The experimental results are as follows in Table 3:

Abstract

The invention relates to a water electrolysis cup, and belongs to the technical field of electrolysis equipment. The water electrolysis cup comprises an electrolysis power supply, and an inner tank provided with a negative electrode and a positive electrode; the positive electrode and the negative electrode are connected with the cathode and the anode of the electrolysis power supply respectively; an pervious diaphragm is arranged between the negative electrode and the positive electrode; the positive electrode is coated with the pervious diaphragm; and the distance (delta) between the pervious diaphragm and the negative electrode is equal to or larger than 0 and is equal to or less than 10mm. The water electrolysis cup can be used for preparing water which is rich in active hydrogen, is low in oxidation reduction potential, and is suitable for drinking.

Description

Technical field [0001] The invention relates to an electrolysis water cup, belonging to the technical field of water electrolysis equipment. Background technique [0002] Water is the source of life. With the progress of society and the intensification of environmental pollution, people are asking for higher and higher quality of daily water (including domestic water, medical water, beauty water, food production and other industrial water, etc.), especially domestic water. Diversified needs. [0003] The daily water used by the people provided by the municipality, even if the water quality safety indicators of the water plant are basically up to the standard, the "faucet water" sent to the people's water terminal has become a (special) slightly polluted water for the following reasons: [0004] 1) The pollution of the water environment is deteriorating, the existing water treatment process of the water plant is outdated, and the quality of the factory water has been difficult to me...
