Abstract
The invention discloses a drinking water softener and a softening method and softening equipment thereof. The drinking water softener is a sustained-release softener which is preferably soluble carbonate sustained-release agent and comprises the following components in part by weight: 1 to 3 parts of soluble carbonate, 2 to 5 parts of calcium carbonate and 2 to 7 parts of clay. A preparation method comprises the following steps of: mixing the soluble carbonate, the calcium carbonate, the clay and water and stirring uniformly; pouring the mixture into a mould; and drying and forming. In the method, the sustained-release agent is prepared from the soluble carbonate and put in a microporous membrane; when hard water flows through a sustained-release softening filter element, the soluble carbonate is slowly dissolved and released through the microporous membrane to further react with calcium ions in the water to produce insoluble calcium carbonate; and finally the insoluble calcium carbonate is filtered by an ultrafilter so as to reduce the calcium ion content of the hard water and fulfill the aim of partial softening. The drinking water softening method has the advantages of small investment, safety and convenient use and is particularly applicable to the softening of household drinking water.
Description
Technical field
The present invention relates to a kind of tap water softening technology.
Background technology
So-called hard water contains a large amount of calcium salts and magnesium salts ionic water exactly.When this water uses in family, can not make soap produce foam, also can on the clothing that is washed, precipitate one deck incrustation scale; When boiling water, can at the bottom of kettle and bottom the thermos flask, tie the hard white incrustation scale of one deck gradually.This is very tedious.
With water softening, avoid a variety of methods of depositing of incrustation scale, often the method for using has:
1) ion exchange method: adopt specific Zeo-karb, the calcium ions and magnesium ions in the water is cemented out with sodium ion.This method is present most common standard mode, as patent CN02142568X, and CN2084049, CN2183363, CN2509174 etc. are described.Its major advantage is: effect stability is accurate, technical maturity.Hardness can be reduced to 0.Adopt the softened water equipment of this mode generally also to be called " ion-exchanger ".But this method is because during household drinking water, invest greatlyyer, and exchange resin needs often to regenerate, and the water of output is soft excessively, and long-term drinking is unfavorable for health.
2) membrane separation process: nanofiltration membrane (NF) and reverse osmosis membrane (RO) all can be tackled the calcium ions and magnesium ions in the water, thereby fundamentally reduce water hardness.Such as patent CN1040745 etc. description.The characteristics of this method are: effect is obviously stablized, and the water after the processing is applied widely; But intake pressure is had higher requirements, and facility investment, running cost are all higher, and the water of output is soft excessively, and long-term drinking is unfavorable for health.
3) precipitator method: handle with lime, soda ash, make Ca in the water
2+, Mg
2+Generate precipitation and separates out, promptly get soft water after the filtration, manganese wherein, iron plasma also can be removed, such as patent CN1106364 etc. description.This method generally can't be applicable to the household drinking water system.
4) dosing method: Xiang Shuizhong adds special-purpose Scale inhibitors, can change calcium ions and magnesium ions and carbanion bonded characteristic, thereby make incrustation scale can not separate out, deposit.Owing to added chemical substance, so the application of water is very limited, can not be applied to generally speaking drink, aspects such as food-processing, industrial production.In civil area, also seldom use.Because the dosing method just stops the generation of incrustation scale from the principles of chemistry, do not reduce water hardness, thus generally be not included in the softening method, but be called scale inhibition.Example is seen CN87105392.
5) electromagnetic method: adopt to add that in water certain electric field or magnetic field change the ionic characteristic, thereby the physical property when changing sedimentary speed of lime carbonate (magnesiumcarbonate) and deposition stops the formation of hard scale.As patent CN1181746, CN2039307, CN2109391 describes.This kind method and dosing method are similar also to be the generation that stops incrustation scale, rather than reduces hardness, so generally also should be called antiscale or scale inhibition.
Summary of the invention
The objective of the invention is variety of issue, a kind of tenderizer that can partly soften tap water is provided at the prior art existence.
To achieve these goals, tap water tenderizer of the present invention is designed to a kind of slowly-releasing tenderizer.The slowly-releasing tenderizer is preferably soluble carbon hydrochlorate sustained release dosage.
Soluble carbon hydrochlorate sustained release dosage is made up of the component of following parts by weight:
The preparation method is: soluble carbon hydrochlorate, lime carbonate, clay and water are mixed and stir, pour in the mould drying and moulding into.
In above-mentioned tap water tenderizer, described slowly-releasing tenderizer also comprises one deck millipore filtration, and the slowly-releasing tenderizer is embedded in the millipore filtration.
The preparation material of described millipore filtration is preferably one or more the mixture in polyvinylidene difluoride (PVDF), polyethylene, polypropylene, the polypropylene cyanogen; The pore diameter range of millipore filtration is between 0.22 micron to 5 microns.
Described soluble carbon hydrochlorate is preferably yellow soda ash or salt of wormwood, especially yellow soda ash.
Another object of the present invention provides a kind of tap water softening method, comprises the steps:
(1) tap water the is flowed through softening filter core of slowly-releasing is handled, and contains the described tap water tenderizer of claim 5 in the softening filter core of slowly-releasing;
(2) filter.
In above-mentioned tap water part softening method,, filter and be preferably ultrafiltration in order to improve the drink water purifying effect.
Principle of the present invention is: when hard water flows through the softening filter core of slowly-releasing, slowly dissolving and discharge of the soluble carbon hydrochlorate in the soluble carbon hydrochlorate sustained release dosage particle through millipore filtration, further with water in the calcium ion reaction generate the lime carbonate insolubles.Be shown below:
Na
2CO
3+Ca
2+＝2Na
++CaCO

Precipitation of calcium carbonate is removed by filter by ultra-filtration equipment subsequently, thereby the calcium ion concn in the water is reduced, and reaches the purpose of part softening water.
Another object of the present invention provides a kind of tap water part remollescent equipment, it comprises softening filter core of slowly-releasing and ultra-filtration equipment composition, be provided with soluble carbon hydrochlorate sustained release dosage and millipore filtration in the softening filter core of slowly-releasing, soluble carbon hydrochlorate sustained release dosage is embedded in the millipore filtration.
Compared with prior art, the present invention has following beneficial effect:
The present invention makes sustained release dosage with the soluble carbon hydrochlorate, and place millipore filtration, when hard water flows through the softening filter core of slowly-releasing, soluble carbon hydrochlorate in the soluble carbon hydrochlorate sustained release dosage particle slowly dissolves and discharges through millipore filtration, further with water in calcium ion reaction generate the lime carbonate insolubles, filter through ultra-filtration equipment at last, thereby reduced the content of calcium ion in the hard water, reach part remollescent purpose.Tap water softening method of the present invention investment supports, safe, easy to use, be particularly useful for the softening of household drinking water.Through treated water of the present invention, thereby calcium hardness is partly removed the fouling tendency of having eliminated water.Simultaneously, the water after the processing has kept certain calcium magnesium density and has been weakly alkaline, helps HUMAN HEALTH.
