Abstract
A kind of full automatic ultra-filtration membrane water cleaning systems, the thickness of this ultra-filtration membrane is 0.5-10 microns, the aperture only is 100-800 dusts, can filter out general commercially available filter can not remove carcinogenic, mutagenesis, teratogenesis shape chemical substance.This system has automatic recoil mechanism, has solved the accumulation of objectionable impurities on fenestra, has guaranteed the use repeatedly of film, water production rate and high standard water quality.Purification system of the present invention is applicable to general family, office, enterprises and institutions.
Description
The invention belongs to water-treatment technology field.
The commercially available cold and hot water drinking-water system that supplies office to use generally is made up of the water source of purifying waste water, refrigerator, electric heater.Be divided into two types aspect the water source of purifying waste water again, a kind of is to use fabric filter, and another kind is the place, water source that is connected on tap water with gac, ultraviolet sterilization apparatus, hollow fiber membrane ultrafiltration device etc., and the water process of purification is freezing or heating is promptly drinkable.The advantage of said apparatus is that the effect of removing pigment, suspended substance and free chlorine is arranged; Shortcoming is that gac etc. is limited to organic adsorptive power, adsorbs must change immediately after saturated.In addition, long-term the contacting with bacterium of gac will produce deleterious nitrite and breed bacteria.Commercially available hollow fiber membrane ultrafiltration device can make carcinogenic low-molecular-weight organic matter of people such as trichloromethane for excessive in the tap water, and tetracol phenixin, nonpolar organic matter etc. do not have separating effect fully.
The purpose of this invention is to provide a kind of office that supplies, the small-sized water purifying plant that enterprises and institutions use improves the water quality of direct drinking water, and makes the automatically unmanned control of entire equipment.
Water cleaning systems of the present invention has an improvement mechanism.Promptly adopt present various ultrafiltration membrance filter devices, in the micropore of its ultra-filtration membrane, with special macromolecular material refabrication one deck ultrathin membrane, sell on this ultrathin membrane can be removed commercially available water purifier can not elimination low-molecular-weight organic matter such as the effect of ethylene dichloride, phenols, aldehydes, ethers, petroleum alkane, nitrite and metal-salt, heavy metallic salt and radioactive substance, also can remove impurity such as bacterium, suspended substance.This ultrathin membrane is very thin, purify waste water by the time resistance seldom, the permeable amount of unit surface is very big.
The manufacturing of this novel ultrafiltration membrane filter is to adopt the film forming method of power shape can be indicated in accompanying drawing 1.Film forming material (1) with ultrathin membrane is dissolved in the solvent (2) earlier, simultaneously thinner (3), softening agent (4), solidifying agent (5) and pore former (6) is mixed in (2) again.Then, water pump (7) is coupled together above-mentioned mixing liquid bath (8) and commercially available hyperfiltration membrane assembly (9).Open water pump, mixed solution (8) is pressed into the micropore internal condensation, crosslinked and fixing of the film of hyperfiltration membrane assembly (9).Mould material (1) becomes the solid deposited thing by liquid state, forms the littler novel ultrafiltration membrane in aperture.
Assembly requirement to commercially available ultra-filtration membrane is:
Film thickness 8-200 micron
Membrane pore size 0.01-1 micron
Mould material is water-insoluble
The film shape is not limit
The film forming mixture formula of power shape is:
| Mould material | Furfuryl alcohol resin furane resin example furfuryl resin acetone-furfural resin chaff ketone resin | The 1-200 mg/litre |
| Thinner | Alcohols, ketone | 1－99％ |
| Softening agent | The O-phthalic acids, phosphoric acid lipid | 0.5-500 mg/litre |
| Solidifying agent | Benzene sulfonyl chloride, sulfuric acid acetate | 0.9-5% |
| Solvent | Water | 1-99% |
| Pore former | Neutral soluble inorganic salt can dissolve tensio-active agent | The 20-1500 mg/litre |
The schema of water cleaning systems of the present invention sees accompanying drawing 2.Its component part is: power forms membrane module (10), three three-way solenoid valves (11), (12), (13), two-way electromagnetic valve (15) by rly. water level gauge (14) control, the time relay or micro-chip (16), water box (17), cold and hot water drain valve (18), (19).When water box (17) is anhydrous, power supply is connected automatically, two-way electromagnetic valve (15) is promptly opened, tap water enters membrane module (10) by three-way solenoid valve (11), and the water that is cleaned enters three-way solenoid valve (12), (13), valve (13) is by the time relay or micro-chip (16) control, valve block is got to dotted line position, water is entered waste pipe (22) in preceding 2-5 minute, with original unclean retentate in the removal system.After reaching the specified time, the valve block of valve (13) recovers original solid line position, makes the water that is cleaned inject water box (17) by pure water inlet (23).But drink cold water purification open cold condenser (20) and tap (18), drink hot water purification heater (21) and tap (19).Rly. water level gauge (14) cuts off two-way electromagnetic valve (15) automatically after water reservoir is filled water purification, closes the water source.In addition, the time relay (16) can be adjusted to every several hours-24 hours, makes two three-way solenoid valves (11), and (12) oppositely once are dotted line position, all make simultaneously valve (13) cooperate waste discharge once at every turn, again water purification is injected water box by pure water inlet (23) then.So repeatedly, unattended.Because the self-timing recoil has solved the obstruction of membrane module (10) and the accumulation of objectionable impurities, has guaranteed life-span, water production rate and the water quality standard of membrane module (10).
