Accompanying drawing explanation

Fig. 1 is the block diagram of the producing device of low sodium healthy water of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

See Fig. 1, the producing device of a kind of low sodium healthy water, including pretreatment unit 1, electric adsorption device 2, nanofiltration or Reverse osmosis unit 3 and after-treatment device 4.Pretreatment unit 1 receives the water source from municipal tap water, through pre- After processing means 1 pretreatment, processed by electric adsorption device 2, nanofiltration or reverse osmosis unit 3 respectively, mixed water Processed by after-treatment device 4 and discharge as direct drinking water.

Pretreatment unit 1 is for tentatively filtering tap water, filters including PP cotton in this utility model preferably Core 11, Active carbon fiber filter core 12 and ultrafiltration apparatus 13, above three defecator can set gradually.For a non-huge sum of money Belong to for polluted source, after pretreatment unit 1, eliminated the bigger inorganic matter of granule in water and organic Pollutant component.The water outlet of pretreatment unit 1 can be provided with Organic substance sensor (OMS) 14, the water after pretreatment is complete Organic pollution level can be monitored, additionally, the outlet of pretreatment unit 1 can arrange the first water outlet by OMS14 Pipeline 15, is used as domestic water to be discharged by the water of pretreatment, this first outlet pipeline 15 can arrange the first electromagnetic valve 16, thus control the discharge of domestic water and the size of output.

Water after pretreatment unit 1 processes then respectively enters electric adsorption device 2, nanofiltration or reverse osmosis unit 3. The water inlet of electric adsorption device 2 is connected with the outlet of pretreatment unit 1, and the outlet of electric adsorption device 2 then connects There is the first regulation pipeline 21 and the second outlet pipeline 22.Electro-adsorption technology is i.e. by applying applied voltage formation electrostatic field, Force ion to move at the electrode with opposite charges, make in water dissolved salts and other charge species on the surface of electrode Enrichment concentrates and realizes water purification/desalination.It is provided with the first regulation valve 23, consequently facilitating adjust on first regulation pipeline 21 Flow on joint the first regulation pipeline 21；Second electromagnetic valve 24 can be set on second outlet pipeline 22, thus control second The draining of outlet pipeline 22 and the size of displacement.

The water inlet of nanofiltration or reverse osmosis unit 3 is connected with the outlet of pretreatment unit 1, nanofiltration or reverse osmosis unit 3 Outlet on then connect have the second regulation pipeline 31 and the 3rd outlet pipeline 32, this second regulation pipeline 31 on be provided with Second regulation valve 33, consequently facilitating the flow on regulation the second regulation pipeline 31.Can be arranged on 3rd outlet pipeline 32 Three electromagnetic valves 34 (non-return valve), its water discharged can be used for washing dish etc., and the washing dish that mineral is many is the cleanest.Nanofiltration or The setting of the concentration ratio of reverse osmosis unit 3, in water to be made, hardness is more than applicable hardness.Nanofiltration or reverse osmosis unit 3 Water inlet and the outlet of pretreatment unit 1 between booster pump 35 can also be set, with constant pressure of supply water, stable supply The water yield.

The first above-mentioned regulation pipeline 21 and the second regulation pipeline 31 are commonly connected to be connected to the water inlet of after-treatment device 4 Water inlet pipe 41 on mouth, water inlet pipe 41 is provided with water quality sensor 42, and the signal detected is fed back to the first regulation Valve 23 and the second regulation valve 33.In this utility model preferred embodiment, water quality sensor 42 includes total dissolved solidss (TDS, Total dissolved solids, be the mineral being generally understood that) sensor and sodium ion sensor.

After-treatment device 4 can carry out sterilization processing etc. to water, and output meets the straight drinking pure water drinking demand.

The manufacture method of low sodium healthy water of the present utility model comprises the steps:

1) pretreatment: after coming in municipal tap water, first passes through 5 μm pp cotton filter cores 11, the rust mud in trap water The suspended materials such as sand, then through Active carbon fiber filter core 12, play adsorption, reduce water the Organic substance in water Colourity, abnormal smells from the patient and various disinfection byproduct (DBP), then into ultrafiltration apparatus 13, reduce the turbidity of water further, plays clean Change effect, and monitored the content of Organic substance in water in real time by OMS14, to have determined Active carbon fiber filter core 12 the most Saturated through absorption, when adsorbing saturated, prompting is changed.

2) purify: pretreated water respectively enters electric adsorption device 2, nanofiltration or reverse osmosis unit 3, at the present embodiment In, nanofiltration or reverse osmosis unit 3 are as a example by nanofiltration.After a pretreated water part passes through nanofiltration, the mineral in water Concentrated, and due to south, the road effect of nanofiltration, in condensed water, sodium ion ratio is reduced；And the most pretreated another Part is by after electro-adsorption, and various mineral concentration, under the effect of electric field, synchronize to reduce, it is achieved low sodium requirement, permissible According to water quality demand, synchronize to be reduced to by the voltage-regulation of electric adsorption device 2 realizes sodium ion and other mineral Suitably value.Then the concentrate minerals after nanofiltration converges with the product water of electro-adsorption, the ratio of sodium suitable according to hardness, low Allocate, i.e. carry out the regulation of TDS and Na ion concentration: regulation process is first to regulate TDS (sign hardness of water), The result detected by TDS sensor controls the first regulation valve 23 and the second regulation valve 24, thus scalable is by the One regulation pipeline 21 and the second outlet pipeline 22 enter into the discharge ratio in water inlet pipe 41, thus by TDS to TDS The direction regulation of preset value (such as 300mg/L) so that in water, hardness is suitable；After TDS regulation, then with similar side Formula carries out Na ion concentration regulation, is adjusted to by Na ion concentration less than Na ion concentration preset value (20mg/L) so that in water Na ion concentration is relatively low；If the water outlet of the first outlet pipeline 21 meets demand, then the second regulation valve 33 can be closed completely Close, if the water outlet of the second outlet pipeline 31 meets demand, then the first regulation valve 23 can be completely closed.Through TDS Produce after regulating with Na ion concentration that hardness is suitable, the healthy drinking water of low sodium.

3) post processing: the water after purification enters post-processing stages, it is ensured that bactericidal effect, fully meets straight drink demand.

In above-mentioned preferred embodiment, by arranging water quality sensor 42 on the water inlet pipe 41 of after-treatment device 4, And regulate the water inlet ratio of two pipelines to regulate TDS and Na ion concentration automatically by two regulation valves.Alternative , it is also possible to water quality sensor 42 is arranged on the outlet of after-treatment device 4 or manually from after-treatment device 4 Water inlet or outlet sampling carry out detection etc.；In addition it is also possible to electric adsorption device 2 and sodium filter/reverse osmosis unit 3 Self regulation exports different TDS and the water of Na ion concentration, or also regulation valve can be arranged on respective water inlet pipe Lu Shang, or the structure of other existing water volume adjustables is set.
