Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
The filtering accuracy of reverse osmosis membrane (RO film) water purification technology, almost can filtering water all impurity and salt in addition up to 0.0001 micron.But the negative effect of high precision RO film is it is very easily blocked up by dirt, for preventing that RO film from being blocked up by dirt, guarantee that RO film produces the patency of film in water process, the RO film of RO water purification machine must guarantee that when producing pure water enough former water rinses RO film surface, so can produce a large amount of waste water.The RO pleurodiaphragmatic in terspace water use efficiency recommendation that the Dow Chemical Company of famous American produces is 15%.At home, water purification machine producer is used more Korea S " Saehan film ", Japan's " eastern beautiful film " and domestic " Correspondent film " etc., and the former water use efficiency of recommendation is also in 25% left and right.
Fig. 1 shows water cleaning systems of the prior art, comprise: the inlet triplet for water 1 connecting by pipeline successively, fore filter group (being formed by the PPF candle filter 8 connecting successively, active carbon filter core strainer 10 and PPF candle filter 11), topping-up pump 13, reverse osmosis membrane filt 15, high-voltage switch gear 18, Postposition carbon filter 19, Postposition carbon filter outlet and water outlet 20, for example tap connects, and high-voltage switch gear 18 outlets are connected with a Pressured water tank 4 by pipeline simultaneously.
As shown in Figure 1, the Water flow-path processed of common water purification machine is that by the pipe core of film, the pure water end through reverse osmosis membrane filt flows out after reverse osmosis membrane filtration for water after pressurization, waste water end keeps uninterrupted discharge of wastewater, waste water proportional valve 16 by a constant rate is discharged waste water, after the discharge of accumulation for some time waste water ratio, add 17 discharges of Wastewater by Electric magnet valve, to guarantee to remove the accumulation of dirt on film.This Water flow-path processed, former water use efficiency is in 25% left and right.
As shown in Figure 2, " few waste water " pure water mechanism Water flow-path of Some Domestic producer is in the flow process of common water purification machine, to have increased a return of waste water device, part waste water is introduced to the entrance of reverse osmosis membrane filt 15, removed the waste water proportional valve 16 of constant rate, with magnetic valve 17, carry out discontinuous blowdown, make the cycling utilization of wastewater of discharge, reduced discharge of wastewater, it is 50% even higher that former water use efficiency is brought up to, but reverse osmosis membrane can not guarantee the output quality of pure water under more and more higher high-concentration waste water surrounding, simultaneously very large to the damage of reverse osmosis membrane, stifled the increasing the weight of of dirt of film, greatly shorten work-ing life.
Fig. 3 is the water cleaning systems that the utility model one embodiment shows, comprise: the inlet triplet for water 1 connecting by pipeline successively, fore filter group, topping-up pump 13, reverse osmosis membrane filt 15, Postposition carbon filter 19, Postposition carbon filter outlet is connected with water outlet 20 by high-voltage switch gear 18, and the outlet of reverse osmosis membrane filt is connected with a Pressured water tank 4 by pipeline simultaneously.Wherein, reverse osmosis membrane filt outlet is provided with discharge of wastewater pipeline, and this pipeline is provided with an impulse electromagnetic valve 14; Pressured water tank 4 by a pipeline and check valve 22 reflux micro-pure water to the front end of reverse osmosis membrane filt 15 for after water processed, immersion reverse osmosis membrane.
As shown in Figure 3, the Water flow-path processed the utility model proposes has been removed the waste water proportional valve of constant rate, by common Wastewater by Electric magnet valve use instead unlatching, making time at 0.1 second with interior impulse electromagnetic valve 14, use discontinuous pulse sewage discharge, by magnetic valve, open fast the closed instantaneous flushing reverse osmosis membrane of the current surface producing rapidly, remove fast the dirt precipitation accumulating on film, with few wash water amount, reach the object of effective cleaning reverse osmosis membrane, significantly reduced the generation of waste water.Compare with common water purification machine, adopt the blowdown of momentary impulse rapidly of the utility model system, the ratio of waste water and pure water can be by waste water 3: pure water 1 is significantly brought up to waste water 1: pure water more than 3 (can be accomplished waste water 1 according to water quality is different: pure water is more than 6), and former water use efficiency is from significantly bringing up to more than 75% less than 25%.
Wherein, the concrete flushing operation time is as follows: remove magnetic valve unlatching, making time, each time of rinsing (0.3 second-0.5 second was) to produce powerful rapidly current between 0.1 second to 1 second, the too short dirt precipitation that can not remove completely on film of single flush time, time is oversize can not produce powerful current, waste water and also developing result not good.Rinse interval time between 15 seconds to 45 seconds at every turn.The instrument that can be used as the ratio that regulates pure water and waste water this interval time, when the good area of water quality or the ultralow discharge of wastewater of customer requirement, can extend to reach interval time the object of water-saving.According to continuous operation output pure water, reach 10 tons of above tests, in former water TDS value 500, with interior area, can accomplish pure water 5: the phenomenon that water flow obviously reduces does not appear in the effect of waste water 1 and reverse osmosis membrane.In former water TDS value lower than 300 with interior area, can accomplish pure water 6: the effect of waste water 1, even higher.Like this, in the good southern area of Chinese water quality, can be higher heighten pure water output, turn down discharge of wastewater, in the situation that big area is used, save a large amount of valuable water sources.
As shown in Figure 3, the utility model has increased pure water reflux, at external placed type pressure pot 4 or directly drink the water outlet of the built-in filer element type pressure pot of machine and punish out a water pipe, by check valve 22, pure water is back to reverse osmosis membrane filt 15 front ends, after water processed, pure water is transported to and in reverse osmosis membrane filt, soaks reverse osmosis membrane.Simultaneously at high-voltage switch gear 18 front ends, increase a check valve 5, when preventing after water processed pure water backflow because high-voltage switch gear decompression causes topping-up pump frequent starting.The principle that increases this reflux is: at reverse osmosis membrane rapidly during momentary impulse blowdown, waste water ratio significantly declines, but the dense water of reverse osmosis membrane blowdown end accumulation is more, that TDS value rises is large (particularly high regional of former water TDS value or promote former water conservancy use 75% more obvious when above).At full water processed, stop producing water after for some time, it is higher that the static penetration theory of reverse osmosis membrane can make pure water bring out water TDS value, is unfavorable for the output of high quality pure water.By this pure water reflux, reverse osmosis membrane is after water processed finishes, and via clean pure water rinsing, immersion, the TDS value of waste water end significantly declines, and significantly reduces to the possibility of pure water end infiltration, has also protected reverse osmosis membrane simultaneously.Compare with " few waste water " water purification machine that other return of waste waters reach water-saving object to reverse osmosis membrane front end, not only do not shorten and extended on the contrary the work-ing life of reverse osmosis membrane, and the high-quality output of pure water is also more secure.
Fig. 4 shows second embodiment of the present utility model.In this embodiment, can increase in pure water water side a water flow sensing unit 7, at reverse osmosis membrane filt 15 water inlet front ends, increase a four-sided valve 6 simultaneously, with computer board, control water circuit system, entering water electromagnetic valve and blowoff electromagnetic valve all adopt impulse electromagnetic valve and the large flow reverse osmosis membrane of not power consumption simultaneously, both urban and rural area at tap water hydraulic higher than 0.2 MPa, can municipal power supply, without topping-up pump, realize water purification machine without micro-discharge of wastewater output pure water under electric condition, more accomplish energy-saving and emission-reduction, meet the requirement that China builds a conservation-minded society.
Above-described embodiment is only for illustrating embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
