Description
Technical field
The present invention relates to nanofiltration water dispenser, particularly a kind of nanofiltration water dispenser and its back-flushing method for being changed without filter core.
Background technology
Drinking water present situation
Water is healthy closely bound up with the mankind, and current pollution of waterhead and water supply secondary pollution seriously threaten the health of people.
Mainly spring, the well water of rural potable water, typically no purification and sterilization are just directly drunk or boiled are drunk.According to
Hygiene department investigates, and has 1.9 hundred million people's drinking water harmful substance contents exceeded.In addition, agricultural chemicals, the continuous increasing of fertilizer amount at present
Plus, drinking water source is heavily contaminated, water pollutant content severe overweight, will cause the danger such as disease popularity, outburst infectious disease
Evil.
Mainly running water, the drummed pure water of urban drinking water（Mineral water）Deng.
The subject matter of drinking public water supply：
1st, with the development of urban industry, urban water resource is subject to industrial pollution, though running water is processed, difficulty reaches comprehensively to be defended
Raw, safety indices.Input channel Long-Time Service lacks necessary maintenance, cleaning and ensures, many pipelines occur seepage, knot
The microbial growths such as dirt, corrosion phenomena, various viruses, bacterium, some aqueducts have algae infestation, have a strong impact on water quality unexpectedly
Amount, causes the secondary pollution in conveying.
2nd, corrosion, the accumulation of pollutants of modern city building roof water tank on the middle and senior level, though cleaned sterilization, still unavoidably secondary dirt
Dye.
3rd, waterworks is principal disinfectant agent mostly using chlorine, and Organic substance in water is acted on chlorine, can generated various to human body
Harmful Chlorination Disinfection By-products, in addition, the residue of chlorine becomes new harmful material with the easy chemical combination of residue of water.
4th, algae is present in water, has a strong impact on Water purification effect；Various odors can be produced, water quality in pipe network is affected；Algae with
Chlorine effect generates various harmful side products, increases the Mutagenicity of water；Some algae（Such as blue-green algae）Algae toxins such as liver can be produced
Toxin, neurotoxin, to health very big threat is constituted.
5th, China's running water safe and sanitary standard is significantly lower than developed countries.Turbidity and colourity and organic concentration are inclined in water
Height, it is limited to the removal effect of some special organic pollutions.
Drink drummed pure water（Mineral water）Subject matter：
1st, the drinking-water secondary pollution problem that underproof " evil mind bucket " causes, " evil mind bucket " is containing various harmful elements and poisonous
Chemical substance, can injure human nerve, cause dizzy.
Barreled, bottled pure water qualification rate are poor, it was reported that the national barreled of Ministry of Public Health's sampling observation, bottled pure water qualification rate are
80% or so, subject matter is that sanitary index, electrical conductivity, strontium, metasilicic acid are unqualified, and the total plate count in sanitary index is exceeded to ask
Topic is projected the most.
When the pure water of barreled is drunk by water dispenser, the problem being secondarily contaminated is serious.
" the evil mind water " of mineral water is pretended to be using running water simple filtration, is flooded market and is difficult to tell truth from falsehood.
Drinking-water mistaken ideas：
It is a kind of water way that many people think that comparison is safe to drink plain boiled water, but there is also many problems：
Boiling water can kill the bacterium of non-refractory, virus in water, but corpse is also in water, and " heat is become into after human body
Source body ", this is come from clinic more common " pyrexia of unknown origin " reason.In addition, boiling water can not remove Mercury in Water Body, arsenic, lead, cadmium, chromium
And the harmful substance such as other organic pollutions.
Plain boiled water loses oxygen too much through boiling, and people both know about for watering flowers and can not breed fish.In the same manner people Jing often drinks
The plain boiled water of anoxic, can be such that human body cell deforms because of anoxic, and this is the major reason for causing canceration.
Drink plain boiled water another problem：It is the chlorine residue in running water, the chlorine residue in water between 90-100 DEG C generates trichlorine
Methane（CHCl3）Concentration highest, and chloroform（CHCl3）Confirm there is carcinogenesis by world medical circle.
So it is very serious to drink injury of the plain boiled water to human body for a long time, because present water pollution is seriously and decades
Front water is completely different.
Water dispenser present situation, although species is a lot, mainly there is following three big series：
Ultrafiltration water dispenser is the relatively early water purification product for occurring, and its filtering accuracy is relatively low, and which results in it cannot filter a huge sum of money
The pollutant of the forms such as category, residues of pesticides, the water after purification is not safe enough.
Reverse osmosis drinking machine, its filtering accuracy is too high, causes mineral matter and trace element in water all to lost, such
Water is too pure, health disappearance.And RO machines（Counter-infiltration）Water wasting expense electricity, is not the good product of energy-saving and emission-reduction.
Nanofiltration water dispenser, it overcomes the drawbacks of ultrafiltration and counter-infiltration, really brings safe and healthy drinking to user
Water.It can not only filter out heavy metal, residues of pesticides that ultrafilter cannot be filtered etc., also overcome the too pure defect of RO machines water,
Degree of leaving is removed, mineral matter and trace element are remained, the water Jing after collecting and filtering apparatus are filtered was not only safe but also healthy.
Existing market nanofiltration water dispenser typically all uses rolling NF membrane, be by film shell, water inlet flow channel separation net,
Nanofiltration diaphragm, water purification collect what runner separation net was closely entwined in central collection tube.One section from rolled film of running water
Into the concentrated water being throttled directly is discharged from the other end of rolled film, and the water purification after filtration flow to center and receives along rolled film
In collector, then it is pooled on outlet pipe.The characteristics of due to its configuration aspects, there is separation net the both sides of nanofiltration diaphragm, the isolation
Net is, in order to support two adjacent nanofiltration diaphragms, and to form certain pipelined channel, but on the one hand the structure increased
The discharge distance of water purification after filter, so as to need larger pressure reduction to promote filter process, on the other hand, it is easy to retain concentrated water
The residuals of side, are mainly manifested in that backwash effect is bad, so as to need many prime safeguard measures, just can guarantee that nanofiltration
Diaphragm effectively works for a long time.Following problem can so be brought：
