Description
Technical field
The utility model relates to a kind of device for purifying potable water, particularly relates to a kind of energy-saving environmental-protection reverse osmosis membrane water generator.
Background technology
Common reverse osmosis membrane drinking water purification process is one of technique the most general of water purifying plant employing in the market.Water inlet by this method, is removed the various hazardous and noxious substances wherein existed, is made water supply quality reach national guidelines for drinking water quality.
To through material there is optionally film be called semi-permeable membranes, generally can only can not be referred to as desirable semi-permeable membranes through the film of solute through solvent.When the dilute solution of same volume (such as fresh water) and strong solution (such as salt solution) are placed in the both sides of semi-permeable membranes respectively, solvent in dilute solution will spontaneously flow to strong solution side through semi-permeable membranes naturally, and this phenomenon is called infiltration.When infiltration reaches balance, the liquid level of strong solution side can exceed certain altitude than the liquid level of dilute solution, and namely form a pressure reduction, this pressure reduction is osmotic pressure.The size of osmotic pressure depends on the inherent nature of solution, namely with the kind of strong solution, concentration and temperature about and have nothing to do with the character of semi-permeable membranes.If apply one in strong solution side when being greater than the pressure of osmotic pressure, the flow direction of solvent is by contrary with original infiltration direction, and start to flow from strong solution to dilute solution side, this process is called reverse osmosis.Reverse osmosis is the reverse locomotory movement of one of infiltration, a kind of under pressure-driven, by means of the separation method that the solute in solution and solvent separate by the selective retention effect of semi-permeable membranes, it has been widely used in the purification of various liquid with concentrated, wherein the most general application example is that reverse osmosis technology principle is under the effect higher than solution osmotic pressure in water technology, these materials and water can not be separated according to other materials through semi-permeable membranes.
But there is serious deficiency at present in this method: use the water rate processed of reverse osmosis membrane too low in prior art.The rate of recovery of single reverse osmosis membrane is only about 15%, and namely the water inlet of 100 milliliters can only the tap water of output 15 milliliters.This shortcoming makes reverse osmosis membrane in scavenging process, cause the significant wastage of water resources, does not meet national environmental protection and reduces discharging requirement.Meanwhile, reverse osmosis membrane can not clean effectively, causes Pore Blocking, and its work-ing life is shortened.
Summary of the invention
The technical problems to be solved in the utility model is to provide a device, can improve the water rate processed of reverse osmosis membrane, can also realize the effective cleaning to reverse osmosis membrane simultaneously.
In order to solve this technical problem, the utility model provides a kind of reverse osmosis membrane water generator, include water pump processed, reverse osmosis membrane, circulation loop and drainage channel, the water-in at water source is connected to the water-in of described reverse osmosis membrane through described water pump processed, the dense water out of described reverse osmosis membrane is connected to described circulation loop and drainage channel respectively, and the influent side of described water pump processed is connected to by described circulation loop, described drainage channel is provided with a magnetic valve, and the pure water outlet of described reverse osmosis membrane is connected to a feed water inlet.
Optionally, described circulation loop is provided with variable valve.
Optionally, described circulation loop is provided with flow monitoring device.
Optionally, described flow monitoring device is connected with described magnetic valve by a total control mechanism.
The utility model is by the introducing of circulation loop, repeatedly can utilize dense water, and then effectively improve water rate processed, improve the pH value of water outlet, in addition, after concentrated stream amount acquires a certain degree, the discharge of dense water can be realized by the unlatching of magnetic valve, and then controlled by water pump processed, utilize the water inlet at water source to clean reverse osmosis membrane surface.So the utility model provides a device, the water rate processed of reverse osmosis membrane can be improved, the effective cleaning to reverse osmosis membrane can also be realized simultaneously.
