Drinking pure closed cycle supply system

Technical field

A kind of drinking pure closed cycle supply system is the utility model is related to, belongs to purifying water process technical field.

Background technology

As the fast development of China's economy is with growing, the various pollutants that all trades and professions are discharged, and automobile are wide Exhaust emissions caused by general popularization, increasingly severe pollution effect is caused to air, food, water needed for human life, In order to which the people that survive can only move heaven and earth to tackle harm caused by various pollutions.In face of the air seriously polluted, state Family has caused great attention, in order to administer and improve harm caused by air pollution, takes a series of behave and pays Huge cost is gone out, has obtained progressively improving.For food by agricultural chemicals, chemical fertilizer, chemical agent, heavy metal, antibiotic and The harm of various hormone medicines and transgenosis, country similarly pays much attention to, and is going into overdrive to strengthen management, and implement A series of Supervision Measures, it is among constantly improving.But the drinking water safety problem in actual life needed for people, mesh Preceding country does not cause higher attention degree also, lacks specification, supervision and control, and the quality of drinking water exists many dangerous Sexual factor, more social concerns and negative effect are triggered, therefore, for water safety, people have to take various sides Formula, such as：Install household water filter, residence district automatically taking water machine water intaking, using bottled water or using the modes such as bottled water come Ensure we daily water consumption safety, but these modes but also there are problems that various.

(1) household water filter is installed

The species of household water filter has mainly divided into micro-filtration water purifier, ultra-filtration water purifier and anti-penetration water purifier at present, Wherein, micro-filtration water purifier uses the water purifier of micro-filter technology, and filtering accuracy is typically in 1-0.1 microns, the filter of common various PP cottons Core, activated carbon cartridge, ceramic element etc. belong to micro-filtration category, and it mainly carries out simple thick mistake by way of absorption Filter, the large granular impurity such as silt, iron rust in filter water, chlorine residue can also be removed, but bacterium that can not be gone in water removal etc. is harmful Material.Ultra-filtration water purifier uses the water purifier of hyperfiltration technique, and filtering accuracy can only filter out the iron in water in 0.1-0.01 microns The harmful substances such as rust, silt, suspension, colloid, bacterium, larger molecular organicses, and the removal effect to small molecule organic pollution Fruit unobvious, the requirement of advanced treating is not reached.Anti-penetration water purifier is that domestic. applications are at most also most commonly seen, and it is constructed Mainly it is made up of three vertically-mounted filter sticks and a horizontally loaded type reverse osmosis unit, first is white PP cottons filter stick (mistake 10 microns of precision is filtered, effect is：Sticky matter, floccule, particle and the impurity gone in water removal)；Second is dark brown filter stick (effect is：Decolouring, taste removal, absorption microorganism)；3rd is that (1 micron of filtering accuracy, effect are white PP cottons filter stick：More The particle and impurity further gone in water removal).Core component in water purifier is that (operating pressure is 3~5bar to reverse osmosis unit Belong to low-pressure membrane), the aperture of film is 0. 01-0.001 microns (only import reverse osmosis unit can be only achieved the precision), the aperture To the clearances such as the harmful components such as arsenic, lead, mercury, chromium, barium, plasma and halogenated hydrocarbons, agricultural chemicals, radioactive particle up to 70% with On；And the clearance of domestic reverse osmosis unit can only achieve more than 50%.Water purifier still has certain in initial install and use Remove the removal of impurity and catharsis, but need to regularly replace filter stick and maintained, use cost is higher, and use During the impurity that is filtered and microorganism remain among system, the accumulation of impurity and microorganism causes the big of bacterium Amount is grown, and causes whole system to form bacteria breed station, does not have any manually or automatically operating function but in water purifier system Three filter sticks are carried out with automation cleaning, excludes impurity and microorganism caused by filtering；Also without any function to system Carry out processing method and the measure of high-temp sterilizing, the defects of these are serious, is present, will necessarily cause various filter sticks and Hidden trouble be present in the amount reproduction of the inside and outside bacterium of reverse osmosis unit, quality of pure water.

Bottled water is all the water prepared by a little more compact simplified first-stage reverse osmosis devices mostly, using high pressure counter-infiltration Device, the water quality of institute's output will be far above household water filter and residence district automatically taking water machine production water quality.But these are small-sized Simple first-stage reverse osmosis device market confusion, lacks supervision and control, there is more disadvantage there is presently no unified standard End：1. the materials such as part, instrument and meter, valve and pipeline used in water generator do not reach foodstuff sanitation-stage requirement, pure Water purification is vulnerable to pollution；2. the storage of pure water is all the static storage in container or bucket, easy breed bacteria；3. pure water Storage container and bucket are all plastic containers mostly, mostly made of regenerated plastics, are easily caused harmful substance and are released to pure water In；4. the filtration system and reverse osmosis unit in water generator do not have any mode and measure to carry out high-temp sterilizing, easily Cause a large amount of breed bacterias of system；It is used in turn 5. purified water bucket is all circulation, every time whether by strict before filling Cleaning, disinfect, people can not understand and confirm, this is also larger hidden danger be present to water quality；6. bottled water Quality additionally depend on filling environment, it is filling after storage time length, and the length of user's usage time, to pure water Quality can produce more uncertain factor.

Meanwhile there is no any label to indicate production unit, date of manufacture, the date of production, quality guarantee period on most buckets Limit, quality standard, production licence, hygiene permits etc. identify, because these more small-sized simple first-stage reverse osmosis devices are general Store-through is technical matters is backward, working condition is poor, no health security measure so that the quality of bottled water cannot be guaranteed at all. Allow people is more inapprehensible to be, also there is fakement phenomena in water, and some retailers are driven by interests, production it is so-called pure Water, in order to not have incrustation scale after allowing people to view to be boiled water with kettle, production process is using the calcium and magnesium in softening resin adsorption water Ion, so as to reach the purpose of the boiled rear non-scaling of water, to prove that the quality of its water is good；In order to allow people to feel bottled water It is in good taste, employ in process of production activated carbon decolourized, taste removal, so as to allow people to feel the in good taste of water, this The so-called device for producing pure water of kind, water is simply squeezed into plastic holding device pass through in activated carbon container i.e. using a water pump Calcium ions and magnesium ions suction-operated and decolouring, the effect of taste removal are completed, such production technology, any waste water is not produced, simply pays The point electricity charge and the cost of labour, can not be to the harmful substance in water body (such as：Arsenic, fluorine, lead, barium, aluminium, mercury, chromium plasma with And halogenated hydrocarbons, agricultural chemicals, heavy metal, antibiotic, radioactive particle etc.) produce any removal effect.

(4) bottled water

Bottled water is typically all what is produced by relatively large enterprise, and usual people contribute to outdoor and travelling drink mostly With, due to being related to the factors such as cost, it is rare to cook, make tea using bottled water as family etc. with water, though and bottled water So there is certain quality assurance, but still can be by the long water produced hidden danger of quality of storage condition and shelf life.

By to above-mentioned four kinds analyzing as can be seen that the water that various modes are obtained all can various degrees with water Insecurity and uncertain hidden danger of quality, if having ignored the quality of water, harm of its hidden danger to people is difficult to expect. The etiologic origin of the mankind is all closely bound up with water mostly, because water is there is too many insecurity factor, once drink or Person has drunk the water dealt with improperly for a long time, will trigger various infectiousness, epidemic disease, or even has more fearful disease Become.Therefore, people must pay much attention to source and the quality of water.
