Abstract
The utility model discloses a water purifier. The water purifier is characterized by comprising a microfiltration filter element, an ultra-filtration filter element and a nanofiltration filter element, wherein the water inlet of the microfiltration filter element is connected with a raw water port, and the water outlet of the microfiltration filter element is connected with the water inlet of the ultra-filtration filter element, the water outlet of the ultra-filtration filter element is connected with the water inlet of the nanofiltration filter element, and the water outlet of the nanofiltration filter element is connected with a drinking water port of the water purifier. The water purifier provided by the utility model has the advantages that the diameters of the filtration holes are gradually increased, so that the impurities are filtered in a step-by-step.
Description
Technical field
The utility model relates to a kind of water purifier.
Background technology
Along with water pollutes constantly aggravation, drinking healthy water is more and more difficult, so water purifier is favored as people's healthy water articles for use, causes the brand in water purifier market more and more.The report that pollutes around water now is a lot, and disclosed domestic tap water quality situation up to standard take " running water truth " as the front cover special topic as before finance and economics medium " new century weekly " impurity: only 50% running water is qualified.Running water just always is the focus that public opinion is paid close attention to, and along with the running water new standard of carrying out in the original plan will be postponed till 2015, running water is related to people's normal life.Really, along with developing rapidly of modernization industry, the pollution of waterhead degree is aggravation rapidly also, adds the interference of running water various factors in course of conveying, and drinking water of today is more and more troubling.Household water filter can better address these problems.
Water purifier also claims water purifier, and water purifier mainly contains household water filter and the large class of outdoor water purifier two.Yet there is the lower situation of water purification ability usually in existing water purifier.
The utility model content
The purpose of this utility model is to provide a kind of water purifier, to solve the above-mentioned problems in the prior art.
The technical scheme that the utility model provides is as follows:
A kind of water purifier, it is characterized in that: comprise a microstraining core, a ultra-filtration element and a nanofiltration filter core, wherein, the water inlet of described microstraining core be connected the mouth of a river and connect, the delivery port of microstraining core is connected water inlet and is connected with ultra-filtration element, the delivery port of ultra-filtration element is connected water inlet and is connected with the nanofiltration filter core, the delivery port of nanofiltration filter core is connected with water purifier and is drunk the mouth of a river and connect.。
In preferred embodiment of the present utility model, this water purifier also comprises a framework, and described microstraining core, ultra-filtration element and nanofiltration filter core are fixedly installed in framework.
Micro-filtration can be held back the particle between 0.1～1 micron, microfiltration membranes allows larger molecular organics and soluble solid (inorganic salts) etc. to pass through, but can stop the seeing through of colloid of suspension, bacterium, part virus and large scale, the operation pressure reduction (effectively motive force) of microfiltration membranes both sides is generally 0.7bar.
Microfiltration process operation minute dead-end filtration and cross-flow filtration dual mode.When dead-end filtration, solvent and see through film less than the solute particles of fenestra under the promotion of pressure is trapped greater than the solute particles of fenestra, usually is deposited on face.Along with the increase of time, the particle of piling up on face is more and more, and permeability of the membrane will descend, and at this moment must stop and cleans the film surface or change film.Cross-flow filtration is that feed liquid is parallel to face and flows under pressure promotes, and the retentate on face is taken away, and keeps a lower level thereby film is polluted.
Ultrafiltration is a kind of pressurization membrane separation technique, namely under certain pressure, makes little molecule solute and solvent pass the special film of certain pore size, and large molecule solute can not be seen through, and stays one side of film, thereby makes macromolecular substances obtain the purifying of part.The ultrafiltration principle is also a kind of film separation process principle, ultrafiltration utilizes a kind of pressure active membrane, colloid, particle and the relatively high material of molecular weight in the lower trap water of extraneous motive force (pressure) effect, and water and little particles of solute are through the separation process of film.When processed water by means of the work of ambient pressure in order to certain flow velocity during by the film surface, hydrone and molecular weight see through film less than 300-500 solute, and greater than the particulate of fenestra, large molecule etc. because sieving actoion is trapped, thereby water is purified.That is to say,, the most of colloid that contains in water can be removed by after milipore filter when water, can remove a large amount of organic matter etc. simultaneously.
Nanofiltration is a kind of membrane separation technique of separating from reverse osmosis technology, be the ultralow pressure reverse osmosis technology continuity and the development branch.Its molecular cut off is in the scope of 80-1000, and the aperture is several nanometers, therefore claims nanofiltration.It is generally acknowledged, NF membrane exists nano level pore, and rejection is about 1nm greater than 95% smallest molecule.Now; nanofiltration is separated from reverse osmosis technology; become the independently isolation technics between ultrafiltration and reverse osmosis technology; oneself becomes an important branch in membrane separation technique through being widely used in the numerous areas such as desalinization, ultra-pure water manufacturing, food industry, environmental protection.
Seen from the above description, the utility model provides a kind of water purifier, it comprises a microstraining core, a ultra-filtration element and a nanofiltration filter core, water from water purifier through out-of-date, at first microstraining core removes the colloid of suspension, bacterium, part virus and large scale in water, ultra-filtration element is removed most of colloid in water and a large amount of organic matters more afterwards, at last, then remove micromolecular impurity by NF membrane, water is purified to greatest extent.Pore size filter of the present utility model makes impurity be filtered step by step from large to small.

The specific embodiment
Specific embodiment of the utility model, with reference to Fig. 1, a kind of water purifier, comprise a microstraining core 2, a ultra-filtration element 3 and a nanofiltration filter core 4, wherein, the water inlet 21 of described microstraining core 2 be connected the mouth of a river 1 and connect, the water inlet 31 that the delivery port 22 of microstraining core 2 is connected with ultra-filtration element connects, water inlet that the delivery port 32 of ultra-filtration element 3 is connected with the nanofiltration filter core 41 connects, and the delivery port of nanofiltration filter core 4 is connected outlet 5 and is connected with water purifier.In addition, this water purifier also comprises a framework 6, and microstraining core 2, ultra-filtration element 3 and nanofiltration filter core 4 all are fixed in this framework 6.
Above-mentioned is only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
