The invention provides a double membrane mutual flushing type double water outlet reverse osmosis water purifier which comprises a reverse osmosis water processing system. The reverse osmosis water processing system sequentially comprises a water inlet, a preprocessing component, a reverse osmosis membrane, a purified water outlet, an ultrafiltration water outlet and a concentrated water outlet. A waste water combination valve is arranged at the end of the concentrated water outlet. The double membrane mutual flushing type double water outlet reverse osmosis water purifier is characterized in that the rear end of the reverse osmosis membrane is divided into a first pipeline and a second pipeline, the first pipeline is connected to the purified water outlet, and the second pipeline is connected with an ultrafiltration membrane; the rear end of the ultrafiltration membrane is divided into a third pipeline and a fourth pipeline, the third pipeline is connected with the ultrafiltration water outlet, and the fourth pipeline is connected with the concentrated water outlet. When ultrafiltration water and purified water are used in the water purifier respectively, the reverse osmosis membrane and the ultrafiltration membrane can be alternately mutually flushed, the service life of the two membranes are obviously prolonged, the performance cost ratio is high, and cost of users for using the double water outlet reverse osmosis water purifier is greatly reduced.
Description
Technical field
The present invention relates to water-purifying machine, particularly a kind of pair of two water outlet reverse osmosis water purifiers of the mutual wash type of film, belong to the improvement technology that has two water outlet reverse osmosis water purifiers now.
Background technology
The current raising along with people's living standard, cleanliness factor to tap water requires also to improve constantly, and water pollutes constantly aggravation, water-purifying machine progressively enters ordinary citizen's family, wherein reverse osmosis water purifier is as the highest product of a kind of filtering precision, because of its water purification effective, moderate cost, the parent who is subject to users looks at, and reverse osmosis water purifier has become the first-selection of safty of drinking water.But family is except daily drinking-water, washing and culinary art water have also occupied very large proportion, as all adopted reverse-osmosis pure water, use cost will be very high (because of reverse osmosis membrane, the RO membrane lifetime can significantly shorten, and it changes price very expensive), simultaneously, because the water production rate of RO film is usually less, also be difficult to meet the washing requirement, adopt and exist the tap water polluted more inadvisable if continue.Therefore, the ultrafiltration water that the use flux is larger, the relative tap water of water quality is safer, as washing and culinary art water, is very wise selection.People have designed two discharging type reverse osmosis water purifiers for this reason.
The two discharging type reverse osmosis water purifiers that exist in the market are broadly divided into two types.
A kind of be directly by reverse osmosis membrane the water after preposition pretreatment system simple filtration directly draw as two water outlets, this water is because of failing thoroughly to remove the objectionable impuritiess such as bacterium in water, iron rust, colloid, water quality is also dangerous.Shown in Fig. 1 is exactly the reverse osmosis water purifier of a kind of pair of discharging type like this, as shown in Figure 1, during its work, tap water directly enters successively the first preprocessing filter element 1, the second preprocessing filter element 3 and the 3rd preprocessing filter element 4 and is processed, after processing, the moisture of output becomes two-way: a road directly flows to two depotition cocks, for washing and culinary art, this part water is because failing thoroughly to remove the objectionable impuritiess such as bacterium in water, iron rust, colloid, and water quality is also dangerous; , after topping-up pump 2 superchargings, then further filter through reverse osmosis membrane 5 on another road, after filtration, is further divided into two-way, and a road just becomes pure water and flows to two depotition cocks after filtration through rearmounted filter core, for directly drinking; Another road is condensed water and discharges through waste water combination valve 7.
Another kind of similar to the above-mentioned type, difference is ultra-filtration membrane to be set in the pretreatment system preposition at reverse osmosis membrane improve water purification degree after pre-treatment, and then wherein a part of water directly flows to pair depotition cocks, for washing and cooking.It is exactly the reverse osmosis water purifier of a kind of pair of discharging type like this that Fig. 2 illustrates, as shown in Figure 2, during its work, tap water directly enters successively the first preprocessing filter element 1, the second preprocessing filter element 3 and ultra-filtration membrane 41 and is processed, after processing, the moisture of output becomes two-way: a road directly flows to two depotition cocks, for washing and culinary art; , after topping-up pump 2 superchargings, then further filter through reverse osmosis membrane 5 on another road, after filtration, is further divided into two-way, and a road just becomes pure water and flows to two depotition cocks after filtration through rearmounted filter core, for directly drinking; Another road is condensed water and discharges through waste water combination valve 7.In this water-purifying machine; described ultra-filtration membrane 41 is in the washing culinary art and directly drink two kinds with all participating in filtration under water state; and there is no automatic flushing device; the life-span of ultra-filtration membrane 41 will significantly shorten, and, after its obstruction, reverse osmosis membrane system is also by influenced; water production rate reduces; system operation time will significantly increase and not machine halt trouble even occur, and then shorten the work-ing life of reverse osmosis membrane system as a series of components and parts such as film, pump, valve, high-voltage switch gears, greatly increase user's use cost.
Summary of the invention
The purpose of this invention is to provide a kind of life-span that can significantly extend reverse osmosis membrane and ultra-filtration membrane, the two water outlet reverse osmosis water purifiers of the high mutual wash type of two films of cost performance, used the cost of two water outlet reverse osmosis water purifiers to reduce the user.
The technical scheme that realizes the object of the invention is, a kind of pair of two water outlet reverse osmosis water purifiers of the mutual wash type of film, comprise reverse osmosis water treatment system, described reverse osmosis water treatment system comprises water inlet successively, pretreatment component, reverse osmosis membrane, pure water and ultrafiltration water out and condensed water outlet, be provided with the waste water combination valve at described condensed water exit end, it is characterized in that, the rear end of described reverse osmosis membrane is divided into the first pipeline and the second pipeline, described the first pipeline is connected to the pure water outlet, the second pipeline is connected with ultra-filtration membrane, the rear end of described ultra-filtration membrane is divided into the 3rd pipeline and the 4th pipeline, described the 3rd pipeline is connected with the ultrafiltration water out, the 4th pipeline is connected with the condensed water outlet.
Above-mentioned pretreatment component comprises the first preprocessing filter element, the second preprocessing filter element and the 3rd preprocessing filter element be cascaded, and between described the first preprocessing filter element and the second preprocessing filter element, is provided with topping-up pump.
Also be provided with check valve, high-voltage switch gear and rearmounted filter core on the first pipeline of above-mentioned reverse osmosis membrane rear end.
Above-mentioned waste water combination valve is arranged on described the 4th pipeline, between described waste water combination valve and condensed water outlet, also is connected with magnetic valve.
