Description
Technical field
The utility model belongs to water-treatment technology field, relates to water filtration and water treatment technology, specifically, relates to a kind of reverse osmosis water purifier system back pressure setting device.
Background technology
Reverse osmosis water purifier is the machine mainly utilizing principle of reverse osmosis to carry out water treatment.Reverse osmosis membrane technology applies certain pressure to water, the mineral element of water molecules and ionic state is made to pass through reverse osmosis membrane, and the most inorganic salt (comprising heavy metal) be dissolved in water, organism and bacterium, virus etc. through reverse osmosis membrane, thus cannot make the pure water penetrated and strict the separating of condensed water that cannot penetrate.It is comparatively reasonable that reverse osmosis water purifier generally arranges Pyatyi filtration: the first step is the cotton filter core of PP, and the second stage preposition particle charcoal filter core, the third stage is extruded activated carbon filter core, and the fourth stage is the RO reverse osmosis membrane filter core of core, and level V is post active carbon (little T33).
There is following problem in conventional reverse osmosis water-purifying machine system: 1, conventional reverse osmosis water-purifying machine is along with the increase of pressure pot pressure in water process processed, and reverse osmosis membrane assembly back pressure increases, i.e. the back pressure problems that causes of pressure pot.2, useless only than increase, pure water water production rate reduces gradually; Namely the problem of reverse osmosis module water amount instability and reverse osmosis module water amount few, the problem that concentrated water drainage amount is large; 3, the pressure pot storage full time is long.
Utility model content
The purpose of this utility model is for prior art Problems existing, thus provides a kind of reverse osmosis water purifier system back pressure setting device.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of reverse osmosis water purifier system back pressure setting device, it is arranged between reverse osmosis module and post active carbon, is provided with back pressure regulator in the pure water pipeline of reverse osmosis module, and the pure water mouth of reverse osmosis module is communicated with the water-in of back pressure regulator by check valve; The water outlet of back pressure regulator is divided into the pipeline of two-way connection, and high-voltage switch gear of leading up to is communicated with pressure pot, the inlet communication of another road and post active carbon.
The outlet of preprocessing filter element is by the inlet communication of entering water electromagnetic valve, topping-up pump and reverse osmosis module, and the condensed water pipeline of reverse osmosis module is discharged by magnetic valve.
The utility model beneficial effect:
1, contributing to realizing purifying waste water with the ratio of condensed water by backpressure regulation is 1:1;
2, realize the double-edged pressure difference of reverse osmosis module by back pressure regulator to stablize, reduce the back pressure problems that water-purifying machine exists.Namely efficiently solve: the back pressure problems that pressure pot causes, the problem that reverse osmosis module water amount is unstable and reverse osmosis module water amount is few, concentrated water drainage amount is large, the problem that the pressure pot storage full time is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is by the following examples can the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Embodiment 1: see Fig. 1.
A kind of reverse osmosis water purifier comprises inlet triplet for water valve 1, preprocessing filter element 2, entering water electromagnetic valve 3, topping-up pump 4, reverse osmosis module 5, check valve 6, back pressure regulator 7, post active carbon 8, magnetic valve 9, pressure pot 10, high-voltage switch gear 11 and depotition cock 12.
Tap water accesses preprocessing filter element 2 through inlet triplet for water ball valve 1 by water pipe, and after preprocessing filter element 2 pre-treatment, by the inlet communication of entering water electromagnetic valve 3, topping-up pump 4 and reverse osmosis module 5, the condensed water pipeline of reverse osmosis module 5 is discharged by magnetic valve 9;
Be provided with back pressure regulator 7 in the pure water pipeline of reverse osmosis module 5, the pure water mouth of reverse osmosis module 5 is communicated with the water-in of back pressure regulator 7 by check valve 6; The water outlet of back pressure regulator 7 divides two-way, and high-voltage switch gear 11 of leading up to is communicated with pressure pot 10, the inlet communication of another road and post active carbon 8.
The outlet of post active carbon 8 is communicated with depotition cock 12.
Automatically the pressure at reverse osmosis module 5 back side is regulated mainly through back pressure regulator 7:
When water purification mechanism water, back pressure regulator 7 pairs of reverse osmosis modules 5 carry out depressurization, simultaneously the uplift pressure of offset pressure bucket 10, ensure the stable of the positive and negative pressure at both sides difference of reverse osmosis module 5, impel the stable of reverse osmosis module 5 net water flux, reduce the quantity discharged of dense water.
Working process:
1, tap water accesses tertiary effluent purification system through inlet triplet for water ball valve 1 by water pipe;
2, water after pre-treatment, enters reverse osmosis module 5 through topping-up pump supercharging;
3, the pure water of former water after reverse osmosis module 5 filters, access back pressure regulator 7 and pressure pot 10, controlled the pressure at reverse osmosis module 5 back side by back pressure regulator 7, avoid pressure pot 10 pairs of reverse osmosis modules to form back pressure;
4, controlled the pressure at reverse osmosis module 5 back side by back pressure regulator 7, stablize the net water flux of reverse osmosis module 5, reduce the quantity discharged of dense water.
