Brief description of the drawings
Fig. 1 is structural representation of the present invention
Detailed description of the invention
For making that architectural feature of the present invention and effect of reaching are had and further understand and be familiar with, useCoordinate detailed explanation with preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of drinking water terminal sterilizing filter, comprises body 1 and is arranged on this pipeThe water inlet 2 at body two ends and delivery port 3, be provided with in body 1 along water inlet 2 and superpose successively to delivery port 3Stenlizing layer 4, water purification layer 5 and removal of heavy metal ions layer 6.
In the present invention, in order to remove chlorine, suspension, the sand grain in filter water inlet 2 place's waterWith impurity and further ensure the cleaning of filter delivery port 3 places water outlet to be positioned at stenlizing layer in body 14, the upstream side of water purification layer 5 and removal of heavy metal ions layer 6 and downstream are equipped with and ensure causing of water cleaningClose layer 7.
Compacted zone 7 objects are to prevent high polyiodine resin, granular activated carbon, cationic ion-exchange resin and heavyMetal nano ball flows out to delivery port is outside.
In the present invention, compacted zone 7 is nonwoven filter disc, the utilization heat being made up of polypropylene or polyester etc.Amount and pressure make the powder such as pottery or plastics sintering filter disc, film filter disc that directly bonding forms, are wound with fibreThe filter disc of dimension, to make plastic foamed generation be relatively the filter disc in the aperture of miaow, the screen cloth filter disc that is made up of nylon etc.The combination of one or more in structure.
The meticulous words in compacted zone 7 apertures are easily stopped up, and the excessive words particle in aperture will flow out, thereforeAperture is 0.1 μ m～0.3mm preferably. The porosity of compacted zone is good in 50%～78% scope.
The main cause that the blocked up words of compacted zone 7 thickness can cause flow to decline, therefore should be below 5mmGood, preferably below 3mm and more than 0.1mm.
Stenlizing layer 4 is made up of high polyiodine resin, and stenlizing layer 4 comprises microorganism to filter, to kill, to removeAnd bacterium, virus microgranular body be object.
The high polyiodine resin of stenlizing layer 4 is that a kind of diameter is the black particle of 0.35～1.2mm spherical shape,It is the sterilised medium of a class contact, penetrability. Its sterilization mechanism can be sketched and be: when bacterium protein is at waterIn moment of directly contact with high polyiodine resin, immediately by attack, generation modification, solidify, bacterial enzyme isUnite destroyed, and cause the microbial deaths such as germ.
High polyiodine resin is the sterilised medium of contact, and in 0.5 second, moment is killed all kinds of harm in waterThe germ of human health, virus and the germ making a variation because of ecological deterioration, virus, harmful bacteria gemma,The harmful microorganisms such as algae spore, the irritated acarid of Susceptible population, red worm, can prevent from drawing by drinking waterVarious diseases and the death such as dysentery sent out, sterilizing rate is more than 99.99%, therefore connecing of high polyiodine resin and waterThe tactile time must be greater than 0.5 second, above as good taking 1 second.
Water can produce free-iodine after too high polyiodine resin sterilization affects the mouthfeel of water, and high polyiodine resinAmount of iodine is higher, and the iodine in high polyiodine resin is just more unstable, and the free-iodine concentration discharging in water is also higher,The mouthfeel of water is just all the more bad; Wherein amount of iodine is relevant to the service life of high polyiodine resin again, and amount of iodine moreHeight, the service life of high polyiodine resin is just longer. Because the high polyiodine resin in stenlizing layer must long service lifeAnd the mouthfeel impact on water is little, thus to select amount of iodine high, and the low poly-iodine of height of free-iodine burst size in waterResin. The amount of iodine of high polyiodine resin generally in 35%～55% scope, the containing of sterilization floor height polyiodine resinIodine amount is preferably in 37%～42% scope.
Water is after too high polyiodine resin, and the free-iodine burst size in water is generally in the scope of 0.3ppm～50ppmIn, free-iodine is too greatly the main cause that causes the mouthfeel of water to decline, therefore should be below 2ppm, with 1ppmBe below good, 0.5ppm is better below.
The high polyiodine resin of amount of iodine in 42%～55% scope also cannot reach under current prior artFree-iodine is controlled at below 0.5ppm.
The degree of drying of high polyiodine resin has a certain impact for the germicidal efficiency of high polyiodine resin. Gao JuIodine resin below 40 DEG C after natural air drying, can cause high polyiodine resin to break and germicidal efficiency has under a littleFall, but do not affect use. High polyiodine resin water content is preserved and is used sterilization in 2%～10% scopeEfficiency the best.
High polyiodine resin is more responsive to temperature, and iodine is a kind of volatile chemical substance, therefore should height is poly-Iodine resin is controlled at below 50 DEG C in assembling and the temperature that uses, taking 0 DEG C above 25 DEG C following as good. TemperatureToo high meeting causes high polyiodine resin to decline service life, and impact is used. The reserve temperature of this water purifier is also with 0DEG C above 25 DEG C be good below, preserves in the cool as well.
High polyiodine resin also has requirement to the pressure of water, and the pressure of high polyiodine resin in water too conference causesIts spherical particle breaks, and affects its germicidal efficiency, therefore should be 1MPa, its withstand voltage condition do not break below,Hydraulic pressure is preferably below 0.5MPa.
Water purification layer 5 is made up of granular activated carbon and NACF.
The free-iodine that high polyiodine resin discharges in water affects the mouthfeel of water, must will be wherein by water purification layer 5And absorption, and it also wants to affect the mouthfeel of water and other the organic and nothing being detrimental to health by AdsorptionOrganic pollutants, comprises the remaining ammonia NH of chemical combination2CL、NHCL2And NCL2With free residual chlorine, hypochlorite fromSon, hypochlorous acid, chlorine, haloform etc., therefore the selection of active carbon just seems particularly important.
Can be enumerated as powdered active carbon, granular active carbon, fibrous activated carbon, piece as active carbonShaped activated carbon, extrusion molding active carbon, sintering activity charcoal etc.
Can enumerate phyteral (timber, cellulose, charcoal, palm shell charcoal as the material of active carbonDeng), ature of coal (peat, brown coal, bituminous coal, anthracite, coal tar wet goods), malthenes (petroleum residual oil, sulphurAcid sludge, oil carbon etc.), spent pulping liquor, synthetic resin etc. carry out charing, and have carried out gas as requiredThe material of activation (calcium chloride, magnesium chloride, zinc chloride, phosphoric acid, caustic soda, KOH etc.) etc. DoFor fibrous activated carbon, can enumerate to be pitch with polypropylene fine (PAN), cellulose, phenol, coalFor the parent of raw material carries out charing, and carry out material of gas activation effect etc.
Form as active carbon can be used powdered active carbon, utilize this powdered active carbon granulation to makeGranular active carbon, granular active carbon, fibrous activated carbon, utilize adhesive to make powder or graininessThe pressed active carbon that active carbon is curing etc.
In active carbon because the contacting of granular active carbon (GAC) and fibrous activated carbon (ACF) and waterArea is large, adsorptivity, water flowing are good, thereby more applicable. Granular active carbon is compared powdered active carbonHave and carry advantages such as changing convenient, difficult obstruction. The pore structure of granular active carbon had both had aperture > 50nmMacropore, also have the mesopore of 2.0～50nm and the micropore of < 2.0nm, pore-size distribution is polydispersity, andWherein exist a lot of mesopores and do not play adsorbing macropore. Granular active carbon is large for the hole adsorbingPart is or not surface, and be adsorbed molecule and need to just can reach micropore through the diffusion of macropore and mesopore and be adsorbed,Adsorption rate is slower. Therefore granular active carbon can adsorb the adsorbate of macromolecule, and to little molecular weightAdsorbate absorption property is poor. And fibrous activated carbon has the structural of excellence compared with granular active carbonEnergy and absorption property, its micro content is large, and the volume of micropore accounts for the more than 90% of total pore volume, micro-pore diameterLittle (about 2nm left and right); Pore-size distribution is narrow, shows a monodisperse distribution; Large (the about 1000m of specific area2/g～3000m2/ g), its micropore is directly opened on fiber surface, thereby adsorption capacity is large, and adsorption efficiency is high, adsorption rateHurry up, be 10～100 times of granular active carbon, and the adsorbate of low concentration is had to good adsorptivity,And that this characteristic is granular active carbon is not available, the free-iodine that high polyiodine resin discharges in water is commonBe the low concentration that is less than 1ppm, therefore fibrous activated carbon has good effect for absorption free-iodine.The cost of fibrous activated carbon is higher compared with granular active carbon, from the viewpoint of usability and cost whileMix use granular active carbon and fibrous activated carbon more applicable. Preferably have as granular active carbonGranularity is that 1～6.3mm, iodine absorption number are that 800～1000mg/g, benzene adsorption rate are 30～50%, methylene blue is de-Look power is the character of 70～80ml/g. Preferably having specific area as fibrous activated carbon is 1000～3000m2/ g, iodine absorption number are that 1000～2000mg/g, benzene adsorption rate are 30～60%, Methylene blue adsorption is250～430ml/g, acid-base value are 5.6～7.0, ignition temperature is to be greater than the character of 500 DEG C.
Removal of heavy metal ions layer 6 is made up of heavy metal nanosphere and cationic ion-exchange resin.
The sun that should select absorption to deliquescent metal and reduce hardness excellence as cationic ion-exchange resin fromSub-exchange resin, wherein sodium type storng-acid cation exchange resin is comparatively applicable. When need to be by the water of high rigidityWhile carrying out soft water, can increase cationic ion-exchange resin in described water purifier material mixture ratio.
Removal of heavy metal ions layer 6 also can not arrange. Especially this water purifier is as ultrafiltration, micro-filtration, anti-Other can not arrange infiltration, ultraviolet lamp sterilization etc. heavily while crossing the terminal sterilizing filter of filter core and filter typeMetal ion is removed layer 6.
In one embodiment of the invention, the terminal sterilization that water purifier can be used as other crosses filter core and filter methodFilter solve other other cross the secondary pollution problem that filter core and the insurmountable bacterium of filter method exceed standard.
Cross filter core and filter method as other, can make with the following method: energy stone filter core, accurate potteryPorcelain filter core, the cotton filter core of PP, reverse osmosis (RO) membrane cartridge, inner pressed ultrafiltration membrane filter element, external pressure type ultra-filtration membrane filterCore, active carbon filter core, the softening filter core of function, ion exchange resin filter core, nanometer KDF filter core and ultraviolet raySterilization etc.; These cross filter core and filter method can freely be changed according to user's demand.
In one embodiment of the invention, the flow of water purifier is 5L/min, current mobile pressure in water purifierBe preferably 0.3Mpa, preferred mounting means is that water purifier is upright, and down, current are by flowing for water inletAs power.
In one embodiment of the invention, the proportioning of material for water treatment is: high polyiodine resin: 30%～40%, and particleActive carbon: 15%～60%, NACF: 15%～40%, heavy metal nanosphere particle: 5%～20%, sun fromSub-exchange resin: 5%～20%. The wherein proportioning ratio of high polyiodine resin, granular activated carbon and NACFPress: 1: 0.5～1.5: 0.5～1 specific proportioning. In this proportioning ratio, as too high in high polyiodine resin ratio,In water after high polyiodine resin filters, free iodine concentration is too high, and granular activated carbon and NACF cannot be inhaledAttached removal, the free-iodine concentration in water is still higher, still affects the mouthfeel of water; As granular activated carbon ratioToo high, because of its adsorption rate slower, poor to the adsorbate adsorption efficiency of little molecular weight, to low concentration in waterFree-iodine adsorption effect is poor, therefore also can there is the problem that free-iodine residual concentration is high; As active carbon fibre dimensional ratioToo high, although all can finely there is not the problem that free-iodine residual concentration is high in the mouthfeel of purifying water effect and water yet,But it has increased production cost greatly, affects practicality.
The advantage of this filter is that stenlizing layer 4 is made up of high polyiodine resin, can be in 0.5 second moment killGerm and the virus of all kinds of harm humans health in water of going out, high polyiodine resin self bacterium that can not grow,Do not produce secondary pollution, the in the situation that of identical sterilization effect, more traditional water purifier structure will simply obtainMany, the water purification layer 5 being formed by granular activated carbon and NACF by the free-iodine in water and absorption, andAnd it also can remove Organic Pollutants In Water and chlorine residue, improve the mouthfeel of water, by heavy metal nanosphere andThe removal of heavy metal ions layer 6 of cationic ion-exchange resin composition can be removed the heavy metal being dissolved in water effectivelyIon and reduction hardness of water, be difficult for stopping up, long service life, and can join with other type filter methodClose use.
