Description
Technical field
This utility model relates to water purification field, particularly relates to a kind of water saving water purifier with rearmounted composite filter element.
Background technology
Along with improving constantly of people's lives quality, big flux and make fresh and alive diseases caused by retention of fluid with becoming water purification industry main flow.
Environmental security and health problem cause the highest attention of the common people.Owing to the flaw of pollution of waterhead and water system makes people give birth to
Apply flexibly and water exists the impurity and solvent being no good for health, cause safe drinking water to become the main of current people's most attention
One of problem.The use of water purifier provides the solution route of safe drinking water problem for people.
There are the following problems for current water purifier:
Waste water ratio is higher, does not economizes on water.According to the Penetration Signature of reverse osmosis membrane, make in order to avoid film surface salt excessive concentration
Become concentration polarization, it is necessary to the strict response rate controlling reverse osmosis membrane, the response rate of general single reverse-osmosis membrane element to control
Less than 15%, the water of such 85% is discharged with the form of dense water.The waste water ratio of general household reverse osmosis film is 3:1, even as high as
5:1, i.e. produces 1 glass of pure water, 3 glasss to 5 glasss waste water of output, and along with the development of use fouling membrane, the permeant flux of film by
Gradually reducing, waste water ratio gradually rises.If if these " waste water " are not used, will result in the biggest water resource waste.Therefore,
The response rate improving reverse osmosis water purification machine is that the difficulties of solution is presently required.The generation of reverse osmosis water purification machine waste water can not keep away
Exempt from, it is achieved non-wastewater discharge is the most impossible, can only take measures to reduce wastewater flow rate.
(2) pressure water storage barrel secondary pollution problem.Owing to reverse osmosis membrane filtration precision is high, thus per membrane area aquifer yield
Ratio is relatively low, and the reverse osmosis membrane application initial stage is relatively costly, needs to join in the process structure of the most traditional classical reverse osmosis water purification machine
Standby pressure water storage barrel is with the use of when meeting application little aquifer yield reverse osmosis membrane assembly (50～150GPD reverse osmosis membrane assembly)
Requirement to the water outlet water yield.Pressure water storage barrel is made up of plastic cement or metal shell and food stage rubber liner, divides up and down in bucket
Two parts, above dress water, below inflation.During water purification machine controlling the water circulation, the water made is stored in rubber liner, when reaching certain pressure
Rear stopping controlling the water circulation；When using water, water is extruded from inner bag by pressure pot, and after the pressure in bucket is less than to a certain degree, height presses off
Pass is opened, and water purification machine is again started up controlling the water circulation.Just because of the pure water made is stored by pressure pot, the volume of the bucket of general configuration
Often it is greater than the amount of being intended for single use, causes the made pure water meeting time of staying long, secondly also have the quality of rubber liner itself
Problem and aging, is thus difficult to avoid that the rubber liner in pressure pot is in use likely to occur microbial growth, Asia
The secondary pollution problems such as nitrate exceeds standard, rubber smell.
And presently commercially available reverse osmosis water purification machine without tub, most reverse osmosis membranes only with Dan Zhi great flux,
Cancelling pressure water storage barrel, after long-time shutdown, the water outlet TDS problem (TDS is more than or equal to 50) such as exceed standard occurs first, Ge Biechang
Also the problems such as bacteria breed is serious can be there is in water that business's rearmounted charcoal filter element is left over for a long time or the water of releasing overnight.
Utility model content
It is big to there is waste water ratio for water purification machine of the prior art or water purifier in this utility model, does not economizes on water, and TDS exceeds standard
Problem, it is provided that a kind of solution shuts down water saving water purifier higher for pure water TDS for a long time.
