Description
Technical field
The utility model relates to reverse osmosis water purifier, is specifically related to a kind of reverse osmosis membrane shut-down system.
Background technology
The typical process flow that hyperfiltration is made pure water is: former water gets into the more medium filter filtration by supply-water pump, and (more medium filter is to utilize one or more filter mediums; Like quartz sand etc.; The water higher at the following turbidity of certain pressure passes through certain thickness granular or on-granulated material; Thereby effectively remove the filter plant that suspended impurity makes clarification of water); Filter back water gets into accurate filter and security personnel's filter, and (accurate filter and security personnel's filter are that the filter core with different filtering accuracies is installed in the corresponding filtering container, make water entering container under pressure see through filter core to reach the purpose of removing minute impurities in the water; The filtering accuracy of accurate filter is generally 5 microns; The filtering accuracy of security personnel's filter is generally below 3 microns), the former water of the low pressure after the filtration gets into the high-pressure pump pressurization, and the former water after boosting gets into the reverse osmosis membrane shut-down system.The reverse-osmosis membrane element that the former water of high pressure sees through the reverse osmosis membrane shut-down system in the processing next part of reverse osmosis membrane shut-down system forms that pure water is laggard goes into water tank and store.Remaining high-pressure thick shrink (also claiming dense water) is discharged after the stop valve step-down.
Reverse-osmosis membrane element is meant that two has the membrane component of film end cap.Reverse-osmosis membrane element is the core parts that hyperfiltration is made pure water; Its operation principle is former water effect membrane component surface after the high-pressure pump pressurization; Because penetration theory; Portion of water in the former water becomes demineralized water through membrane component is drawn, and the salinity in the former water goes out along with the former water of another part becomes concentrated water drainage, and this process has some small molecule salts and sees through membrane component.The salt rejection rate of reverse osmosis membrane=(1 – produces water salt content/water inlet salt content) * 100%; We call high desalination rate membrane component to the high relatively reverse-osmosis membrane element of salt rejection rate according to different salt rejection rates; Call low salt rejection rate membrane component to the low relatively reverse-osmosis membrane element of salt rejection rate; General use the reverse osmosis unit salt rejection rate height of high desalination rate membrane component but aquifer yield is low, and use the reverse osmosis unit of low salt rejection rate membrane component opposite, its aquifer yield height but salt rejection rate is low.Chinese patent document CN201578990 discloses a kind of spiral wound dual channel convection current reverse osmosis membrane assembly and membrane component.
General counter-infiltration system is to divide two sections layouts a plurality of reverse osmosis units that have with a kind of reverse-osmosis membrane element of salt rejection rate; The former water of the dense water of first section corresponding each reverse osmosis unit discharge as second section corresponding each reverse osmosis unit; Just the water inlet salt content of two sections reverse-osmosis membrane elements is different, and the leading portion salt content is low, and the back segment salt content is high; Two sections reverse-osmosis membrane element is not to be in best duty before and after will causing like this, and the efficient of system is lower.
The utility model content
The purpose of the utility model provides gives full play to high desalination rate membrane component and low salt rejection rate membrane component advantage, high efficiency reverse osmosis membrane shut-down system.
The technical scheme that realizes the utility model purpose is: a kind of reverse osmosis membrane shut-down system, its design feature is: comprise low salt rejection rate film group and high desalination rate film group.Low salt rejection rate film group comprises 2 to 4 identical low salt rejection rate membrane components; And each reverse-osmosis membrane element all is furnished with corresponding shell; Thereby form corresponding 1 low salt rejection rate reverse osmosis unit; Each low salt rejection rate reverse osmosis unit parallel connection each other is provided with; Also be that the water inlet of each low salt rejection rate reverse osmosis unit is communicated with by corresponding pipeline and forms the water inlet of reverse osmosis membrane shut-down system jointly; The pure water outlet of each low salt rejection rate reverse osmosis unit is formed first pure water outlet of low salt rejection rate film group jointly by corresponding pipeline connection, the dense water out of each low salt rejection rate reverse osmosis unit is communicated with and the common first dense water out that forms low salt rejection rate film group by corresponding pipeline.
Said high desalination rate film group comprises 1 to 3 identical high desalination rate membrane component; And each high desalination rate membrane component all is furnished with corresponding shell; Thereby form corresponding 1 high desalination rate reverse osmosis unit; Each high desalination rate reverse osmosis unit parallel connection each other is provided with; Also be that the water inlet of each high desalination rate reverse osmosis unit is communicated with by corresponding pipeline and forms first water inlet of high desalination rate film group jointly; The pure water outlet of each high desalination rate reverse osmosis unit is formed second pure water outlet of high desalination rate film group jointly by corresponding pipeline connection, the dense water out of each high desalination rate reverse osmosis unit is formed the dense water out of reverse osmosis membrane shut-down system jointly by corresponding pipeline connection.
First pure water outlet of said low salt rejection rate film group and second pure water outlet of high desalination rate film group are formed the pure water outlet of reverse osmosis membrane shut-down system jointly by corresponding pipeline connection; The first dense water out of low salt rejection rate film group is connected through first water inlet of corresponding pipeline with high desalination rate film group.
The utlity model has positive effect: the reverse osmosis membrane shut-down system of the utility model adopts a plurality of high desalination rate membrane components and a plurality of low salt rejection rate membrane component simultaneously; Each a plurality of low salt rejection rate membrane component is arranged in leading portion, and the aquifer yield when the former water process of seawater is hanged down the salt rejection rate membrane component is high; High desalination rate membrane component is arranged in back segment; Salt rejection rate when having guaranteed the dense water of leading portion through high desalination rate membrane component is high; Can bring into play the advantage separately of two kinds of membrane components effectively, so promptly guaranteed system aquifer yield guaranteed salt rejection rate again, improved the efficient of system greatly.
