Problems solved by technology

Its advantage is that it has an excellent effect on water purification, but its disadvantage is that nano-ceramics (activated carbon blocks with high specific surface area sintered by mesophase technology) have high requirements for production technology, and for tap water with high hardness, the pH may exceed 8.5 after water production
Another example is the patent No. ZL201120509347.0, which is a non-diaphragm electrolytic water cup for producing water rich in negative hydrogen ions. The titanium-based inert anode member and the inner wall of the bottom plate of the cup are used to set a gap with a δ range of 5mm ≥ δ > 0. , the water production mechanism is to utilize the difference between the mass transfer reaction lagging behind the electrochemical reaction when water is electrolyzed under a small current. The advantage of this electrolysis water production cup is that it avoids that the pH may exceed 8.5 after water production, and the disadvantage is the purification of water. The effect is not as good as the previous one
The common problem of the above two electrolytic water cups is that the power consumption of water production is relatively high

Embodiment 1

[0022] The purified water cup of present embodiment sees figure 1 , including an inner pot 1 with a water filling port and a pouring port on the top and a power supply 4, the inner pot 1 is made of stainless steel and directly serves as a cathode electrode, and the power source 4 uses a 24V asymmetrical alternating pulse electrolysis power supply.

[0023] An anode 2 is arranged at the inner bottom of the liner 1 , and a porous hydrophobic plate 5 is arranged on the anode 2 . The anode is an inert electrode that is sprayed with platinum group oxide on a titanium plate, and the anode 2 and the liner 1 (that is, the cathode) are respectively connected to the positive and negative electrodes of the power supply 4 .

[0024] Near the anode electrode 2 in the liner 1, there are secondary filter layers with conductivity from low to high in the direction of water flow, which are activated carbon fiber filter membrane 3-1 and ultrafiltration membrane 3-2 respectively. The secondary f...

Embodiment 2

[0031] The purified water cup of this embodiment is basically the same as the first embodiment, the difference is: 1) the inner tank 1 is not directly used as the cathode electrode, but the cathode electrode surrounding the inner wall of the inner tank 1 is separately set in the inner tank 1; 2) in the inner tank 1 The joint surface of activated carbon fiber filter membrane 3-1 and ultrafiltration membrane 3-2 is coated with bamboo charcoal with a thickness of 2 mm that has been treated with nano-activation and uniform mesopore modification as the third filter layer. The fineness of bamboo charcoal is about 60-80 mesh .

Abstract

The invention relates to a purification cup and belongs to the technical field of electrochemistry and membrane filtration water treatment. The cup comprises an inner container and a power source, wherein the inner container is provided with a negative electrode and a positive electrode, and the positive electrode is arranged at the bottom in the inner container. The positive electrode and the negative electrode are connected with an anode and a cathode of the power source respectively. The portion close to the positive electrode in the inner container is provided with at least two levels of filtering layers with the filter precision from low to high in the water flow direction. The filtering layers have conductivity and are located between the negative electrode and the positive electrode. According to the water cup, electrochemistry water treatment and filtration are integrated to form an organic whole in which electrochemistry treatment and filtration are inseparable and cooperative, and therefore deep purification of source water is achieved.

Description

technical field [0001] The invention relates to a device for purifying domestic drinking water, which belongs to the technical field of water treatment. Background technique [0002] It is generally considered that boiling tap water for drinking is the easiest way to ensure drinking water safety. In fact, boiling tap water does not mean it is safe to drink, because boiling water cannot "kill" heavy metals, arsenic, cyanide, nitrite, organic pollutants (such as pesticides, insecticides, synthetic detergents and other harmful substances), Residual chlorine in tap water will react with humic acid and fulvic acid in source water to produce toxic carcinogens such as trihalomethanes and haloacetic acids, and the heating process will accelerate their formation. [0003] At present, the electrolytic water cups of the patented technology are all without a diaphragm structure, such as a reduced water electrolytic water cup without a diaphragm in the patent No. ZL201020582802. The ef...
