Description
Technical field
The present invention relates to household reverse osmosis water purifier functions expanding, filter element cleaning function is improved and the technical scheme increased and economize on water, particularly a kind of can the water purification backwash type three saturating water purifier of quality reverse osmosis washed of medicine gas washing, belong to improvement and the innovation of technical filed of drinking water purifying treatment.
Background technology
Along with the progress of growth in the living standard, science and technology, the purity requirements of drinking water is also improved constantly by people, and water pollutes and constantly aggravates, and water purifier has stepped into the family of ordinary citizen. ultra-filtration water purifier can filter the pollutant such as microorganism in water, Organic substance, colloid, virus, safety, clean, reservation mineral, anti-penetration water purifier effluent quality close to pure water, Non-scale, safer, mouthfeel good, much cleaner, both water purifiers have all won the favor of users. but two kinds of water purifiers there is also water kind battle, a lot of users have shelved the plan buying water purifier because of kith and kin's suggestion disunity, also have impact on the development in water purification market to a certain extent. additionally family is except daily drinking-water culinary art water, tableware, food, fruit and vegerable washing water purification also occupies very big proportion, as all used reverse-osmosis pure water then to become at the corresponding levels high, it is mainly reflected in two aspects: current common anti-penetration water purifier many employings polypropylene spray welding filter element and active carbon filter core are as preprocessing filter element, both filter element filtering principles are that dirt is received in absorption, and easily saturated, saturated filter element can discharge pollutant on the contrary in filtered water, so needing frequently to change filter element, anti-penetration water purifier often filters one liter of pure water needs the reverse osmosis discharging three to four liters to retain dense water, because above two filter element is only capable of retaining the visible solid particulate pollutants such as silt, and the major parts such as virus and bacteria organic-matter chemical pollutant colloid can be transferred through, small part is adsorbed by filter element, so the dense water pollutant content retained by reverse osmosis membrane is uncontrollable, should not as tableware food fruit and vegerable slurry, additionally trap water mineral content is far above former water, scale is bigger, water quality is harder, should not as clothes washing and plantation water, it is discharged into floor drain more and causes waste.
The saturating water purifier of double; two quality reverse osmosis using ultrafilter membrane as preposition pretreatment to solve the problems referred to above producer have developed. Use ultrafilter membrane to have the advantage that the work principle of filter of ultrafilter membrane is that screening retains filtration as preposition pretreatment, do not receive dirty absorption, partial suspended pollutant can be discharged by just rinsing, energy limited prolongation ultrafilter membrane service life; Most of pollutant of former water can be filtered by ultrafilter membrane, retains water mineral and hydrone, and in the ultrafilter membrane filtered water that reverse osmosis membrane retains, only content of mineral substances, higher than former water, safety clean, is adapted for the desirable water quality of washing tableware food fruit and vegerable.
At present double; two water quality water purifiers mainly have two types on the market: a kind of is adopt absorption to receive dirty type polypropylene spray welding filter element to add the active carbon filter core cartridge combination saturating water purifier of double; two quality reverse osmosis as pretreatment, along with people's understanding to water purifier and the raising to water quality requirement, this series products has been gradually backed out market at present; Ultrafilter membrane is additionally adopted to add the activated carbon combination saturating water purifier of double; two quality reverse osmosis as pretreatment exactly.
The double; two several forms of water quality water purifier of common ultra filtering reverse osmosis film and the washing form of ultrafilter membrane and dense water service condition in the market.
Shown in Fig. 1 is adopt dead-end filtration, without the double; two water quality water purifier of ultrafilter membrane reverse osmosis of flushing pollution discharge function. The list that pretreatment uses props up external pressure ultrafiltration membrane filter element, and pipeline is series pipe, and tap water enters the first pretreatment ultrafiltration membrane filter element 2 through raw water tubes road 1, and filtered water is divided into two-way: a road flows directly into double; two depotition cock 13, for washing and culinary art; Another road flows to next stage filter element active carbon filter core 3, after the supercharging of intensified pump 6, filters further through reverse osmosis membrane 7, after filtration, is further divided into two-way, and a road is that pure water flows to double; two depotition cock 14, for directly drinking; Another road is dense water and discharges through waste water ratio 9, and dense water is wasted. In this water purifier, described ultrafilter membrane 2 is cooked in washing and is directly drunk two kinds and both participates in filtration with under water state, ultrafilter membrane is that dead-end filtration does not have auto-flushing dirt eliminating function, float, Organic substance, gel and the crystallizable mineral blocking that namely ultrafilter membrane 2 can be trapped in a short time. Reverse osmosis membrane system is also by impacted; aquifer yield reduces; system operation time is significantly increased even there is not machine halt trouble, and then reduces the service life of a series of components and parts such as counter-infiltration system such as film, pump, valve, high-voltage switch gear, is greatly increased the use cost of user.
Ultrafilter membrane shown in Fig. 2 adopts cross flow filter forward to rinse, namely the ultrafiltration blowoff line 12 of blowoff electromagnetic valve 4 it is connected and installed with in ultrafiltration putamina bottom, former water is entered the first pretreatment ultrafilter membrane 2 by pipeline 1, leach water purification and be divided into two pipelines, one tunnel flows to ultrafiltration clear water faucet 10 for ultrafiltration water purification through ultrafiltration water pipeline 9, one road flows to the second preprocessing filter element 3, entering reverse osmosis membrane 6 after the supercharging of intensified pump 5, reverse osmosis membrane 6 filtered water is divided into two pipelines: a road connects pure water tap 11 for pure water pipeline; One tunnel connects ultrafiltration blowoff line 12, and reverse osmosis concentrated water enters floor drain through ultrafiltration blowoff line 12. When rinsing ultrafilter membrane, blowoff electromagnetic valve 4 is opened, and relies on former water flow velocity to rinse the suspended contaminant in membrane tube, and emits, it is impossible to solve the problem that former water soaks gel, organic deposition attachment blocking membranous wall, crystallizable mineral blocking fenestra for a long time.
Market also has and publicizes the anti-penetration water purifier realizing water purification recoil pretreatment ultrafilter membrane by some device, realize the design of water purification recoil as shown in Figure 3 by water-retention air bag.Former water enters the first intrinsic pressure ultrafilter membrane 2 of pretreatment by inlet pipeline 1, leaches water purification stream respectively and flows to ultrafiltration clear water faucet 10, water-retention air bag the 4, second preprocessing filter element 6. Flowing into reverse osmosis membrane 8 after flowing into filtered water intensified pump 7 supercharging of the second preprocessing filter element 6, reverse osmosis membrane 8 filters pure water and flows to pure water tap 11 via pipeline 9. Reverse osmosis concentrated water. During former water square impact, the blowoff electromagnetic valve 5 of blowoff line 3 is opened, and relies on former water flow velocity flushing membrane inner suspension pollutant. All having certain transmembrane pressure during in view of ultrafiltration membrance filter water, namely influent side pressure is higher than producing water water purification side and water-retention air bag 4, so when the water purifier former water of shutdown is not disconnected and opens bypass, water-retention air bag 4 can not realize water purification recoil. Water-retention air bag 4 also becomes, because of the frequently change of former water pressure, the source of trouble that problem takes place frequently, and easy explosion as too high in hydraulic pressure, ultrafilter membrane damages to cause water hammer effect to cause.
In sum, above-mentioned use ultrafilter membrane suffers from the drawback that do not have ultrafilter membrane flushing pollution discharge function as the anti-penetration water purifier of pretreatment more, or have ultrafiltration flushing pollution discharge function but only have former water forward pre-washing function, it is only capable of discharging suspended contaminant in part water, the obstinate pollutant of blocking fenestra, film influent side membranous wall can not be removed; Cannot prevent because the long-time static immersing filter element of former water (often eats the time for two hours with family's breakfast, lunch and dinner every day, water purifier working time every day is calculate for six hours, water purifier filter element static immersing time every day is 18 hours) the deposition attachment that ultrafilter membrane and reverse osmosis membrane are formed of the Organic substance in water that causes, gel, mineral and Crystallization Plugging, lacking the special maintenance means used by convenient effective industrial purifier filter element, filter element can not effectively be extended service life; It is only capable of using ultrafiltration water purification and reverse-osmosis pure water, it is impossible to allow user while drinking reverse-osmosis pure water, also easily the reverse osmosis of safety clean can be retained ultrafiltration water purification Collection utilization washing tableware food fruit and vegerable, cause water resource waste.
