Summary of the invention
In order to overcome existing water purifier complex structure, pipeline is longer, leak source is too many, ratio of desalinization is higher, pH value descends excessive, the deficiency that has concentrated water discharge, water purifier shell (filter cylinder) can not bear high pressure, oscillating pressure, the deficiency of leaking easily, the invention provides a kind of water purifier, each main purification is integrated in the water purifier filter cylinder (filter flask), and this water purifier pH value in the process of purifying treatment municipal tap water descends little, the certain proportion desalination is arranged, do not emit dense water outward, this water purifier filter cylinder can bear high pressure, oscillating pressure, antileaking.
The technical solution adopted for the present invention to solve the technical problems is: this water purifier comprises water purifier filter cylinder, ultra-filtration membrane, desalination membrane etc., and ultra-filtration membrane and desalination membrane place in the water purifier filter cylinder jointly, and the product water of ultra-filtration membrane (seeing through liquid) enters desalination membrane.Desalination membrane mainly adopts reverse osmosis membrane or nanofiltration membrane, and reverse osmosis membrane and nanofiltration membrane are commonly used with coiled reverse osmosis membrane and rolling nanofiltration membrane mainly in daily.The desalination membrane water inlet can be loaded dechlorination device or dechlorination material to the requirement of chlorine residue before ultra-filtration membrane, the dechlorination material can adopt gac or copper zinc alloy (KDF).
This water purifier filter cylinder comprises cylindrical shell, end socket, sealing-ring, block etc., there is annular recesses inside, barrel port place, end socket places in the barrel port place, gap between cylindrical shell and the end socket is sealed by sealing-ring, block places the annular recesses of inside, barrel port place to block end socket, end socket is limited in the cylindrical shell not because of hydraulic pressure moves outward, has so just formed an encloses container, various main purification are contained in the encloses container.The annular recesses of inside, barrel port place is to be made by cylindrical shell self material, the cylinder material at barrel port place is by distortion can make annular recesses as the ring expansion spinning process, its respective external forms annular convex ring, the annular recesses at barrel port place and annular convex ring are generated mutually by the same part material of cylindrical shell, promptly form annular recesses simultaneously at the corresponding outside annular convex ring that forms of cylindrical shell in inner barrel, cylindrical shell can adopt metal pipe material, and metal pipe material is that height is also commonly used with the stainless steel tube class often in daily life.The block that is stuck in the annular recesses of inside, barrel port place makes end socket firmly be limited in the barrel port, the water purifier filter cylinder can bear very high hydraulic pressure like this, unless block is cut off or squeeze crack by end socket because of hydraulic pressure, the water purifier filter cylinder of this structure can bear very high pressure can be up to the hydraulic pressure of 10Mpa.Above-mentioned end socket, sealing-ring, block structure all can be adopted in the cylindrical shell two ends, or an end adopts the said structure the other end to adopt other structure such as end socket and cylindrical shell to make an integral body.End socket can be made into various structures according to purification process, as end socket is made be with one section cylindrical shell then end socket and filter cylinder cylindrical shell form many spaces, each space is according to technology filling purification or scavenging material.
The municipal tap water is trapped through taking off most suspended substances after the chlorine residue ultrafiltration membrane treatment, bacteriophage, colloid, all kinds of macromole.The product water of ultra-filtration membrane (seeing through liquid) can reach the requirement of direct-drinking water, and its water quality has alleviated the burden of desalination membrane greatly considerably beyond the water inlet requirement of desalination membrane.
The dense water of desalination membrane is received on the water tap water purifier performance generation considerable change.People use water tap in life all be to be interrupted to use.Desalination membrane can not discharge dense water simultaneously when producing water, to become that full dose filters no longer be cross flow filter to desalination membrane like this, desalination membrane can not form the frictional belt under full dose filtration state, and any film producer all forbids desalination membrane is adopted the full dose filter type in conventional desalination membrane uses.Desalination membrane can not form the frictional belt in full dose is filtered can make the ratio of desalinization of desalination membrane reduce greatly: the ratio of desalinization of reverse osmosis membrane can drop to 40% by 98%, the ratio of desalinization of nanofiltration membrane can drop to 20% even lower by 80%, pH value descends little, often drops to 7.1 by 7.3.Can wash so that the unlikely fouling of desalination membrane is blocked desalination membrane when washing dish for using it for anything else when opening dense faucet water.The municipal tap water through after the ultra-filtration membrane pre-treatment again after desalination membrane is handled such water be unusual safety and Health.
It is very universal that ultra-filtration membrane, desalination membrane have all made standard series, particularly hollow fiber ultrafiltration membrane and coiled reverse osmosis membrane and the application of rolling nanofiltration membrane now.Because ultra-filtration membrane, desalination membrane are integrated with the water purifier filter cylinder, thus this water purifier can do compactly, simple.
