A kind of low-pressure energy-saving water-saving reverse osmosis mineralized direct-drinking healthy water deviceTechnical field
The present invention relates to a kind of low-pressure energy-saving water-saving reverse osmosis mineralized direct-drinking healthy water device, be that a kind of process multiple-stage treatments such as municipal tap water or surface water, underground water employing high-pressure pump and ultralow pressure RO film are purified removed objectionable impurities specifically, then through too much little mineralising equipment, output direct-drinking healthy wetting system, equipment has the characteristics of energy-saving and water-saving in this process.
Technical background
Though domestic existing reverse-osmosis treated device can filter the objectionable impurities in the water, must consume a large amount of former water, and power consumption is high.Prior art is subjected to the restriction of its device structure, can not carry out reuse to these water, like this, though solved the problem that purifies water, the cost of paying is to waste a large amount of former water, consumes a large amount of electric energy, and lack mineralising equipment and the measure of science sterilization and disinfection, can not directly drink.
This just needs to invent a kind of water water quality that can guarantee to produce, and the reverse osmosis of energy-saving and water-saving adds the direct-drinking healthy wetting system that mineralising adds sterilization and disinfection equipment again, and a kind of low-pressure energy-saving water-saving reverse osmosis mineralized direct-drinking healthy water device of the present invention just arises at the historic moment in such cases.
Summary of the invention
The purpose of this invention is to provide a kind of water water quality that can guarantee to produce, again the reverse osmosis mineralising equipment of energy-saving and water-saving.
For reaching above purpose, the present invention adopts following technical scheme:
The former water of handling through pretreatment unit pressurizes through high-pressure pump, enters the ultralow pressure reverse osmosis membrane, is spendable pure water by reverse osmosis membrane is that part of; After the mineralising device processes, pure water becomes straight drink mineral water.Most waste water is back on the pretreatment unit by check valve in this process, and small portion waste water is byvariable valve 2 dischargings, to keep the cleaning of reverse osmosis face.Because waste water is under the cooperation of check valve and variable valve, major part is back to pretreatment unit and utilizes again, therefore, has saved a large amount of water.Simultaneously, because adopted the ultralow pressure reverse osmosis membrane, also greatly reduce energy consumption.
A kind of low-pressure energy-saving water-saving reverse osmosis mineralized direct-drinking healthy water device of the present invention; what high-pressure pump adopted is the constant voltage high-pressure pump; because the hydraulic pressure of constant voltage high-pressure pump output is constant; like this; water also is constant to the applied pressure of reverse osmosis membrane in the reverse-osmosis filtering device; thereby protected the long-term normal work of expensive reverse-osmosis filtering device, avoided the detrimentally affect to reverse osmosis membrane fluctuated of hydraulic pressure.
Here, the pre-filtering treatment facility is made of quartz sand filtration device, activated charcoal filter, softening filter, the accurate filter that is connected together of contacting in regular turn, check valve is connected between activated charcoal filter, the softening filter, both can promote the clean level of current through reverse-osmosis filtering device, promote osmosis filtration efficient, simultaneously, can make hydraulic pressure more constant.Adopt ultralow press mold, required pressure only is the nearly 1/3 of the required pressure of high-pressure membrane, thus the energy consumption of greatly reducing.
Compared with the prior art the present invention has the big characteristics of wasting water less, lower consumption, and makes 1 liter of pure water and need only discharge 0.51-0.65 and rise waste water, and wastewater discharge only is 1/5 of a traditional way; With the amount pump, high-pressure membrane needs 15-25Mpa, and low-pressure membrane only needs 6-10Mpa, is nearly 1/3 of traditional way.And to produce water be mineral water, can directly drink.Say that thus water purifying plant of the present invention is real energy-saving and water-saving direct-drinking healthy wetting system.
Description of drawings
Accompanying drawing is the structural representation of one embodiment of the present of invention
Specific embodiment
As shown in the figure, a kind of low-pressure energy-saving water-saving reverse osmosis mineralized direct-drinking healthy water device of the present invention is to realize like this, the pre-filtering treatment facility that comprises former water, the high-pressure pump 6 that is connected with the pre-filtering treatment facility, the reverse-osmosis filtering device 7 that is connected with high-pressure pump 6, reverse-osmosis filtering device 7 links to each other withmulti-micro mineralization device 8,ozonizer 9, gasliquid mixer 10, produces water at last for straight drink mineral water, is stored in the mineral substance water pot 11.Whereinozonizer 9 also can adopt various sterilization devices such as UV-lamp.The pre-filtering treatment facility comprises quartzsand filtration device 1, activatedcharcoal filter 3,softening filter 4, accurate filter 5.The quartz sand filtration device also claims more medium filter, silt in the energy filtering water, suspended substance, heavy metal etc., activated charcoal filter is removed peculiar smell, heterochromatic, and softening filter reduces water hardness, impurity in the further filtering water of accurate filter is with the cleaning of the water of the reverse osmosis membrane of guaranteeing to flow through.Reverseosmosis unit 7 adopts the ultralow pressure reverse osmosis membrane, and energy-conservation power savings is obvious.Multi-micro mineralization device 8 can adopt the controllable type multi-micro mineralization device, also can adopt compound multi-micro mineralization device.
