Technical Field

The utility model relates to a water purification unit, in particular to hydrogen-rich water purification unit.

Background

The household water purifier and the commercial water purifier sold in the market are full of scales and various in patterns, the core components of the household water purifier and the commercial water purifier are filter elements, and the core technology of the household water purifier and the commercial water purifier is membrane technology. The filter elements have different membranes and different water purification effects. The water purifier sold in the market at present mainly comprises three filter elements, namely an ultrafiltration membrane, a nanofiltration membrane and a reverse osmosis membrane.

The pore size of the ultrafiltration membrane is about 10nm, which is the largest of the three membranes. The ultrafiltration membrane can effectively intercept pollutants such as colloid, rust, suspended matters, silt, macromolecular organic matters and the like in water, but has no function on harmful substances such as bacteria, viruses, heavy metal ions and the like with the diameter less than 10 nm. The water from the ultrafiltration membrane water purifier can not be directly drunk, and must be boiled for drinking, so that the water can not reach the height of household high-quality direct drinking water.

The reverse osmosis membrane has a pore size of about 0.1nm, which is the smallest of the three membranes. The existing working mode treatment process of conventional pretreatment and RO reverse osmosis is complex, mature and stable, high-quality purified water can be stably obtained to meet the requirement of direct drinking of families, but the working mechanism of the RO reverse osmosis technology causes two main defects of the household water purification equipment, which prevents the household water purification equipment from developing to the high-end market in a large area, the first defect is that the water yield of the RO purified water is only three to four times due to the working mechanism of the reverse osmosis technology, namely, about 70 percent of wastewater is generated in each water purification treatment, and the disadvantages of the conventional pretreatment and RO reverse osmosis water purification equipment are very obvious under the condition of very rare water resources; the other disadvantage is based on the working mechanism of reverse osmosis, which can intercept and filter all the substances except water molecules, i.e. it can remove the pollutants in the water and filter out the mineral substances which are beneficial to the health of human body, and the long-term drinking of the water is not good for the health of human body.

Through the analytical research to domestic water purification unit commonly used in above two kinds of markets, it is difficult to discover that no matter the domestic water purifier in the existing market adopts the low-end machine of ultrafiltration filtration or the high-end water machine of using the RO technique, people can not satisfy the high-end demand that people are good for health and technological intelligence along with the continuous improvement of living standard, and drinking water equipment must satisfy convenient and practical, energy-concerving and environment-protective.

Therefore, a hydrogen-rich water purifying device is provided.

Because the water source is pretreated before entering the nanofiltration filter 7, most impurities in the water are removed, and the nanofiltration filter 7 only needs to be used for removing harmful substances such as viruses, bacteria, heavy metal ions and the like, the pressure required by the water pump is greatly reduced, the generation amount of wastewater is also greatly reduced, and therefore, electric energy and water resources are effectively saved; the aperture of the nanofiltration membrane is about 1nm, the aperture is between that of the ultrafiltration membrane and that of the reverse osmosis membrane, and the nanofiltration membrane is closer to the reverse osmosis membrane. The nanofiltration membrane can intercept all substances intercepted by the ultrafiltration membrane and can also intercept harmful substances such as viruses, bacteria, heavy metal ions and the like. Electrostatic interaction is formed between the nanofiltration membrane and electrolyte ions, the charge intensity of the electrolyte salt ions is different, so that the rejection rate of the membrane to the ions is different, and in a multi-element system containing ions with different valence states, due to the south-of-the-road effect, the selectivity of the membrane to different ions is different, and the proportion of different ions passing through the membrane is different. Nanofiltration is ion selective due to negatively charged groups on or in the nanofiltration membrane, which interact electrostatically to block the permeation of multivalent ions, but allow monovalent ions to pass through.
