Embodiment
The principle of first preferred embodiment of the present invention as shown in Figure 2, it is a first-stage reverse osmosis direct-drinking water device.KDF activated charcoal filter 1 wherein is made up of KDF strainer and charcoal filter, is composed in series integrative-structure between the two mutually.The KDF strainer is by (the KDF Fluid Treatment of U.S. KDF fluid handling company, Inc.) Fa Ming a kind of copper zinc alloy strainer, it is designed in the pure water treating processes, can be whole or in part chlorine, lead, arsenic, cadmium, chromium VI, chromium III, selenium, mercury, bacterium, lime carbonate, magnesium and the material that contains the arsenic element be disposed (referring to the network address http://www.kdfft.com of KDF company).Activated charcoal filter then can be disposed the chlorine in the water and Multiple Pesticides, insecticide, weedicide.Activated charcoal filter mainly is to reach filter effect by the minute aperture adsorption, so often need (some months) to change.
As can be seen from Figure 2, the present invention has also adopted a reverse-osmosis treated device as its core on the basis of KDF activated charcoal filter 1.Reverse osmosis technology claims Reverse Osmosis Technology again, and it is considered to one of greatest technological breakthrough of twentieth century.After the World War II, the best approach that huge fund is sought processing drinking water is thrown by United States Government, through multidisciplinary interaction, inspired by bionics, find this most reliable most economical again method of reverse osmosis technology (referring to network address http://www.ext.nodak.edu) at last.Reverse osmosis technology is to utilize reverse osmosis cross-stream film, separates and get rid of wide spectrum impurity by the operating pressure of water.When this reverse osmosis cross-stream film is flowed through at the water source of input under the effect of particular job hydraulic pressure, will form the cross-stream phenomenon.In cross-stream, the water of input is separated into two strands of current: the first is assembled the pure current that form after penetrating into reverse osmosis cross-stream film by water molecules, and it is concentrated through the center pure water pipe and obtains; It two is to concentrate current, and its reverse osmosis cross-stream film of flowing through under the promotion of work water pressure is also taken away automatically outward by reverse osmosis cross-stream film and refused to ooze wide spectrum impurity in the film appearance, so condensed water herein is actually the undrinkable water that contains wide spectrum impurity.The advantage of cross-stream design is to clean reverse osmosis cross-stream film appearance automatically, and its energy consumption is low, efficient is high, and can carry out accurate fluid separation at ion, molecule, nano level and ultra micro molecular level.Because the infiltration aperture of reverse osmosis cross-stream film has only 5 dusts to 20 dusts, therefore, the molecular energy that dewaters penetrates into reverse osmosis cross-stream film and is gathered into beyond the pure current, nearly all metal ion, salt soluble in water, institute's organic/inorganic substance and most molecular wt surpass 100 organic substance (MW), comprising three methine halides, various agricultural chemicals, insecticide, weedicide, various bacterium and virus, i.e. various impurity more than 99.8% all can be refused to ooze beyond reverse osmosis cross-stream film and cleaned automatically.
As can be seen from Figure 2, the direct-drinking water device in the embodiment of the invention one is mainly by placed in-line KDF charcoal filter 1, reverse-osmosis treated device 2 and charcoal filter 5 are formed successively.
During work, city tap-water flows into through water meter 10, available family expenses charcoal filter 11 and valve 12, after water source input tube 23 flows into a end input of selfclosing gate valves 9, outputs to 21 pressurizations of tap water force (forcing) pump by the b end again, sends into KDF charcoal filter 1; Flow through successively then reverse-osmosis treated device 2, charcoal filter 5 carries out filtration treatment, can obtain required pure water; Described pure water is held output through c, the d of selfclosing gate valve 9, is transported to direct-drinking water tap 7 or direct-drinking water pressure water storage tank 8 through pressure switch 6, and described direct-drinking water pressure water storage tank can be 3.2 gallons of pressure water storage tanks.
Wherein, selfclosing gate valve 9 is mechanical four-way valves; 6 hydraulic pressure that are used to detect pure water of pressure switch, when hydraulic pressure rises to preset value (for example 40PSI), pressure switch can be cut off the power supply of tap water force (forcing) pump and pure water force (forcing) pump, and makes selfclosing gate valve 9 be in off state, and this moment, whole device can suspend the production pure water.When hydraulic pressure reduces (for example being opened because of the direct-drinking water tap) to preset value, pressure switch 6 can reclose the power supply of tap water force (forcing) pump, and make connect between a, the b of selfclosing gate valve 9 and c, d between connect, this moment, whole device began to produce pure water again.
As can be seen from Figure 2, the condensed water that reverse-osmosis treated device 2 produced can directly be recovered to retrieving arrangements such as family expenses water butt 15, washing machine 14 through condensed water output tube 24, allows the user can utilize these condensed water to wash clothes or towards toilet etc.In addition, also can condensed water be sent into and reclaim in the pressurized tank 18 by backwater pressure pump 17, this reclaims pressurized tank and also is connected with the household tap water system, and and keep apart by a check valve 13 between the input water source of whole direct-drinking water device, when family lavatory or washing machine etc. needed water, the condensed water in the recovery pressurized tank 18 just can confuse city tap-water and be spent.
The principle of second preferred embodiment of the present invention as shown in Figure 3, it is a two steps ro direct-drinking water device.Wherein, charcoal filter 5 is connected between the input terminus of the output terminal of tap water force (forcing) pump 21 and first step reverse-osmosis treated device 2, pure water output terminal at first step reverse-osmosis treated device 2 also is connected to a pure water force (forcing) pump 3,1 of KDF charcoal filter is connected between the input terminus of the output terminal of pure water force (forcing) pump 3 and second stage reverse-osmosis treated device 4, and the pure water output terminal of second stage reverse-osmosis treated device 4 then connects the c end of selfclosing gate valve 9.The condensed water output terminal of first, second grade reverse-osmosis treated device then is connected to corresponding condensed water retrieving arrangement through condensed water output tube 24 respectively.
Adopt the reason of two steps ro, be because some amount of water containing chlorine very big cities such as (for example) Shanghai from the beginning, add that gac is easy to lose efficacy, as fail in time to change, then chlorine will enter reverse osmosis cross-stream film and destroy the micropore of reverse osmosis cross-stream film, therefore cause a certain amount of toxic substance or dopants penetration to advance reverse osmosis cross-stream film, thereby polluted pure water.Like this, just might endanger user's health and lives.For guaranteeing the reliability of direct-drinking water device, after our pure water process water purification force (forcing) pump 3 pressurizations, send into second stage reverse-osmosis treated device 4 again with 2 outputs of first step reverse-osmosis treated device, make pure water through two steps ro, thereby can guarantee its extra best best.
Among the present invention, KDF charcoal filter 1 shown in Fig. 3, first, second grade reverse-osmosis treated device 2,4 all can be contained in the portable plastic casing, form a portable direct-drinking water device, its gross weight has only about three kilograms, volume is also very little, is convenient to travel on official business carry.Each independently portable direct-drinking water device can produce 80 gallons of pure water every day.Because its volume is little in light weight, therefore it can be placed in any place easily, also it can be hung over the somewhere.On casing, be provided with four rapid-acting couplings, water source input tube, two condensed water output tubes and pure water output tube can be connected respectively to corresponding apparatus.
