Description
Technical field
The present invention relates to water treatment field, especially the electrodialysis water purifier.
Background technology
Existing electric osmose formula water purifier is to be based upon on the basis of ion-exchange membrane, perhaps ion exchange resin is clipped between the two membranes and uses as film.Cationic membrane only allows positive ion by stopping negatively charged ion; Anionic membrane only allows negative ion to pass through and the characteristics design that do not allow positive ion to pass through, She Ji electric osmose formula fresh-water generator is simple in structure like this, but the cationic membrane that only allows positively charged ion to pass through easily makes high-valence cationic roll up the shelly dirt on semi-permeable membranes, make the physical disturbance of pair of films, equipment claimed is often changed the ion semi-permeable membranes.The life cycle of film is short.Owing to used ionic membrane or ion exchange resin, the recovery of film also to need to be unfavorable for environment protection with acid, alkali.So even generally lack the situation of fresh water in the world today, ionic membrane electric osmose formula fresh-water generator is since invention in mid-term in last century, because its inherent defect is not used widely in producing or living.
Another water treatment technology of relatively extensively implementing at present of quoting is " a pressure reverse osmosis method ", and its advantage is the purification efficiency height, the purity height of the water that purifies.The utilization ratio that distinct disadvantage is a water is low, and 1 ton of pure water of every production needs the unpurified water of 3-5 ton.Next is that the pressure reverse osmosis membrane easily stops up, and every work for some time just needs to clean or change.The 3rd is the equipment price height, can not extensively promote.The 4th is directly to utilize the higher water of hardness to desalinate, and need utilize ion exchange resin to do rough purification.
Summary of the invention
Purpose of the present invention is for providing a kind of simple in structure, easy to use, high-voltage electrodialysis water purifier that cleaning water is high, free from environmental pollution.
The technical scheme that realizes the foregoing invention purpose is as follows:
High-voltage electrodialysis water purifier, has one or more water purification unit, among each water purification unit, have just vertical, negative two pole plates, two vertical porous fence are housed in the middle of two-plate, two porous fence are divided into cathode chamber with the water purification unit, three spaces of water purifying chamber and anode chamber, lower end in water purifying chamber has water-in, the upper end has the water purification water outlet, has anodal water outlet in the cathode chamber upper end, has the negative pole water outlet in the anode chamber upper end, fence is made by filter cloth or through-hole foam plastic plate or porous ceramic plate, just, the strut member that has the support fence of insulating material composition in anode chamber and the water purifying chamber, just, negative electricity interpolar voltage is 100-2000V, just, applied electric field intensity in anode chamber and the water purifying chamber is 5-100V/cm.
By the water purifier that a plurality of water purification unit is formed, the electrical connection between the water purification unit is adopted and is connected in parallel or series connection earlier, then each series connection group is connected in parallel again.
All inlet tube and outlet tubes adopt metallic conduit after leaving the water purification unit, and with lead these metallic conduits are coupled together, and form the electric field isolation screen.
Do not need dismounting equipment when the present invention in use needs to clean, need only exchange positive and negative electrode, so that the incrustation scale that condenses on the electrode comes off from electrode.The incrustation scale that comes off can be gone out with current.Like this, the nothing of equipment dismounting life cycle further prolongs, and working cost further reduces.
The present invention compares with the pressure reverse osmosis type water purifier of current trend, and following advantage is arranged:
1. the utilization ratio height of former water, the water purification rate of recovery of pressure anti-penetration water purifier has only 50-70%, and utilization ratio of the present invention is generally between 70-95%.
2. weight of equipment is light, and per hour producing 1 ton of pressure anti-penetration water purifier weight of purifying waste water is 1 ton, and the weight of the present invention of equal treatment capacity has only 45kg.
3. it is low to consume energy, and is example to handle underground water for quoting water, whenever obtains 1 ton of water purification, and the pressure reverse osmosis type is clean
Hydrophone needs 8 kilowatt-hours of electricity consumptions, and power consumption of the present invention is less than 1 kilowatt-hour.
The present invention compares with present ionic membrane electrodialysis, and following advantage is arranged:
1, because the electric field degree that is adopted is high more than 5 times, so efficient is high more than 5 times.
2, structure is simpler, and failure rate descends.
3, adopt the bigger porous material in aperture at interval, be difficult for the knot slope and stop up, do not need to purify under the Scale inhibitors condition water of any hardness.
4, working cost is low: purifying hardness is that the underground water of 400-1000mg/l (in lime carbonate) is hardness when being 200mg/l, and expense per ton is no more than 1 yuan; When the water that replaces the ion exchange resin ebullated bed to purify specific conductivity 100 μ S to specific conductivity was water below the 10 μ S, expense per ton was no more than 0.1 yuan.
In view of above-mentioned, the invention provides a kind of highly purified purifying waste water, to water energy sterilization and elimination peculiar smell, the charged particulate in the removal water and the technology of the salt and the reduction water hardness, method is simple, scale is changeable, work under the sewage condition of higher pollution concentration again, and working cost is cheap, such water treatment technology, multiple use is arranged, can extensively promote the use of.
