Description
Technical field
The present invention relates to technical field of water purification, more particularly to a kind of big flux ultrafiltration soft water integral water purifier.
Background technology
As the improvement of people's living standards, the water quality safety of drinking water is increasingly paid close attention to.The water in current portions area
Matter situation is harder, the impurity in existing filtering apparatus for drinking water energy filter water such as suspension, sediment, iron rust etc., but right
It can not be filtered absorption of in most calcium ions and magnesium ions, cause the calcium ions and magnesium ions concentration in water higher, influence the heat transfer of household electrical appliance
Or refrigerating efficiency, increase energy consumption, cause the waste of resource；Increase various copper tube equipment to block, corrode, reduce making for copper tube
With the life-span, copper tube cannot be used again when serious；In addition water hardness height also result in soap and cleaning agent detersive efficiency lower,
The black dull problems such as stiff of the in disorder clothes matt, come out of pachylosis, hair after bathing.
Therefore in order to ensure drinking water safety and health, quality of the life is lifted, the use of water softener is gradually popularized.It is existing soft
Water technology main flow has three kinds：First, removing calcium ions and magnesium ions using hyperfiltration, this loom is also referred to as water purification machine, can not only removed
Calcium ions and magnesium ions, while other ions are also removed, production water is pure；Second, with magnetization method, calcium ions and magnesium ions crystallization condition is destroyed, reaches anti-
The only purpose of fouling；Third, use ion-exchange, soften resin with specific sodium form, with sodium ion by the calcium ions and magnesium ions in water
Cement out.Tenderizing machine in the market typically carries out water demineralization using ion exchange principle.
Existing water softening device major part function is single, only considers the removal effect to the calcium ions and magnesium ions in water quality, and to water
In suspended material, particulate, colloidal substance, bacterium and virus etc. without intercepting filter effect.It is public such as patent CN105384215A
A kind of water softening device has been opened, the production water of water softening device, regenerative process are controlled by the detected value of water hardness meter, ensure the softening of water quality
Effect, but filter layer is not provided with, it is still poor without filter effect, producing water water quality effect to the impurity in water quality, germ etc..
Patent CN103159349A discloses a kind of water softening device, although being provided with primary filter in ion exchange resin front end
Filter core, using PP cotton filter cores or active carbon filter core, but the filtration grade of PP cotton filter cores is thicker, can only filter precipitation
Thing, suspension, there is no filter effect to colloid, larger molecular organicses, germ etc.；Active carbon filter core is even more susceptible to plugging ask be present
Topic, the salt solution of resin regeneration can flow through active carbon filter core in addition, more cause filter core adsorption saturation problem so that the longevity of filtration core
Order short, it is necessary to frequently change.Patent CN104326598A discloses a kind of family expenses water softening device, there is provided micro-filtration filter screen, resin container,
The three-level filter systems such as milipore filter end-filtration, filtration grade is more, complicated, causes tube structure big, space-consuming, and super
Filter is arranged on behind resin container, and pollutant is trapped in resin container on the contrary, it is impossible to effectively protects resin container, existing defects.
To sum up, for the research of water softening device, following defect in the prior art be present：Feature is single, only considers softening work(
Can, there is no interception result to other impurities, germ in water；Filter element filtering level is more, complicated, causes volume big, filtration core
There is no self-cleaning function pollution soon, flux decline is fast, short life.
