The device fills market gaps, changes the situation that the present pure water has no nutritive value and alkalescence, and provides novel alkalescent mineralized pure water, which is suitable for people of all ages and benefit to human health.
Description
Technical field
The utility model relates to a kind of device for making of pure water, especially a kind of device for making of the weakly alkaline mineralising pure water as tap water.
Background technology
On the domestic market, produce at present as the almost homogeneous reverse osmosis (RO) membrane process that all adopts of bottled and drummed pure water of tap water.This technology cost is extremely low, based on very high purity.But also exist two major defects that can not be ignored: one is owing to based on very high purity, and some mineral substance that needed by human is taken in and trace element are almost all removed clean, do not have any nutritive value except quenching one's thirst; Its two in this pure water, H
+Concentration is greater than OH
-Concentration is so be slightly acidic (pH value: 5.0-7.0).As everyone knows, it is obviously unhelpful to HUMAN HEALTH that long-term drinking has no the sour water of nutritive value.Especially minor, the more unsuitable long-term drinking of pregnant woman and the elderly.In fact with this kind pure water as tap water, be human a kind of helpless selections under the water surrounding severe contamination.
Summary of the invention
In order to overcome, have the slightly acidic of the made pure water of reverse osmosis (RO) membrane process now and contain any mineral substance hardly, two defectives of trace element, the utility model provides a kind of device for making of weakly alkaline mineralising pure water, its water outlet is weakly alkaline, and has kept necessary little amount of mineral and the trace element of human body.
The technical scheme that its technical problem that solves the utility model adopts is: changing the RO film on the basis of existing reverse osmosis (RO) membrane process is nanofiltration membrane, with the mineral substance and the trace element that keep considerable part in the water of source and increased little electrolysis process, specifically by pre-treatment, weakly alkaline mineralising pure water producer, three parts of sterilization filling are formed.The technical process of preprocessing part is: source water enters quartz sand filtration, charcoal absorption successively after topping-up pump is pressurized to 0.3 MPa, as source water is that soft water is that river lake water can directly enter the smart filter of 1-2 micron, as be that hard water is that underground water then should exchange through ion exchange resin, adjust its specific conductivity and about 300, enter smart filter again.Obviously the pre-treatment of this pre-treatment and existing reverse osmosis (RO) membrane process is identical, owing to be that known technology is not generally given unnecessary details.Weakly alkaline mineralising pure water producer is the key device in the utility model water preparation process flow process.This device is made up of nanofiltration membrane and electrolyzer.Dense water out in nanofiltration membrane is equipped with operating pressure table and relief valve successively, regulates operating pressure that this relief valve makes nanofiltration membrane about 0.15 MPa, in the pure water outlet of nanofiltration membrane liquid crystal specific conductivity display instrument is housed.Source water enters nanofiltration membrane after pre-treatment, under the effect of above-mentioned operating pressure, finish inverse osmosis, it goes out electrical conductivity of water and obtains dynamic monitoring and can be controlled between the 40-50, and electrolyzer is one has three to connect the microscler cylindrical container that the mouths of pipe are made with insulating material.The middle part mouth of pipe is a water-in below at two ends positive electrode and this electrolyzer of negative potential being installed respectively, top is anodal water outlet near the mouth of pipe of positive electrode, the mouth of pipe near negative potential is the negative pole water outlet, two water outlets all are equipped with flowrate control valve, the pure water that is entered electrolyzer by nanofiltration membrane all is small molecules or small-micelle water, loses electronics at positive electrode and has formed positive ion (H
+) excessive regional area, this regional water potential is discharged through anodal water outlet on the occasion of being slightly acidic.Water forms negative ion (OH at the negative potential electron gain simultaneously
-) excessive zone, this regional water potential is that negative value is weakly alkaline.Flow out through the negative pole water outlet.Its pH value can be carried out dynamic monitoring by the liquid crystal pH value display instrument that is installed on this.Obviously can be by to the volts DS of different numerical value, the selection of electric current and the increase and decrease effective contact area of electrode and obtain the ideal electrolysis effectiveness, may command pH value is between 7-8.Regulating flowrate control valve in addition also can finely tune the pH value of water outlet.Because the mineral substance that is kept in the pure water of nanofiltration membrane preparation and the positive ion (Ca of trace element
++Zn
++Deng), in electrolyzer, do directed moving to negative potential, so by the effusive pure water of negative pole water outlet, its concentration is strengthened relatively, mineralization degree is improved.Through ultraviolet ray or ozone sterilization, can put on market.The principle of work of nanofiltration membrane, galvanic provide and sterilization, can are known technology so be omitted.
The beneficial effects of the utility model are, have filled up the market vacancy, and will change all pure water must not have any nutritive value and the weakly acidic market status.A kind of all-ages novel weakly alkaline mineralising pure water useful and harmless to HUMAN HEALTH is provided.
