Abstract
The utility model relates to a reverse osmosis device. The reverse osmosis device comprises a collecting tank (1), a high pressure pump (2) and a reverse osmosis membrane (4) which are connected with one another from front to back in sequence, wherein a one-way valve (3) is arranged between an outlet of the high pressure pump (2) and a water inlet side of the reverse osmosis membrane (4); and a thick water side of the reverse osmosis membrane (4) is connected with an electric slow opening/closing valve (5). The reverse osmosis devices adopts the one-way valve and the electric slow opening/closing valve, so that the reverse osmosis membrane can be prevented from being damaged due to instantaneous high pressure and air backflow which are caused during on and off of the high pressure pump, and the reverse osmosis membrane can be protected well.
Description
Technical field
The utility model relates to a kind of reverse osmosis unit.
Background technology
Reverse osmosis unit utilizes the selection permeability principle of reverse osmosis membrane, when giving the pressure that one of solution presses greater than naturally osmotic, the flow direction of solvent will with original infiltration opposite direction, begin one side flow from concentrated solution to weak solution, in order to realize separating of solute and solvent, this process is called counter-infiltration.
In the reverse osmosis unit in the past, between high-pressure pump outlet and reverse osmosis membrane influent side, check valve is not set, backflow so when high-pressure pump quits work, can produce air, thereby when restarting, can produce partial high pressure or pneumatic hammer causes very large damage to reverse osmosis membrane because of steam-water mixing; The opening and closing speed of the magnetic valve that is connected with the dense water side of reverse osmosis membrane in addition is very fast, and the moment of opening and closing is very large to the impulsive force that film causes, and namely common so-called water hammer also is easy to damage reverse osmosis membrane.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of reverse osmosis unit that can well protect reverse osmosis membrane is provided.
The purpose of this utility model is achieved in that
A kind of reverse osmosis unit is connected with collecting pit, high-pressure pump and reverse osmosis membrane by pipeline in turn from A-P, is provided with check valve between high-pressure pump outlet and the reverse osmosis membrane influent side, and reverse osmosis membrane dense water side in upper strata is closed valve and linked to each other with electronic changing down slowly.
Compared with prior art, the beneficial effects of the utility model are:
The utility model reverse osmosis unit uses check valve and electronic changing down slowly to close valve, has avoided air to backflow and high-pressure pump is opened the instantaneous pressure (pneumatic hammer, water hammer) that produces when stopping to the injury of reverse osmosis membrane, has well protected reverse osmosis membrane.
Description of drawings
Fig. 1 is the structural representation of the utility model reverse osmosis unit.
Wherein:
Collecting pit 1
High-pressure pump 2
Check valve 3
Reverse osmosis membrane 4
Electronic changing down slowly closed valve 5.
The specific embodiment
Referring to Fig. 1, the utility model reverse osmosis unit, be connected with collecting pit 1, high-pressure pump 2 and reverse osmosis membrane 4 by pipeline in turn from A-P, be provided with check valve 3 between the influent side of the outlet of high-pressure pump 2 and reverse osmosis membrane 4, the dense water side of reverse osmosis membrane 4 is closed valve 5 and is linked to each other with electronic changing down slowly.
Water body enters from collecting pit 1, by check valve 3, filters through reverse osmosis membrane 4 electronic changing down slowly in the situation of closing valve 5 unlatchings under the effect of high-pressure pump 2.
Owing to electronicly change down slowly that to close valve 5 slow in opening and closing, thus high-pressure pump 2 open and situation about stopping under impulsive force that reverse osmosis membrane 4 is caused can obtain very large slowly-releasing, can not cause damage to reverse osmosis membrane 4; And check valve 3 avoided backflowing of air in high-pressure pump 2 situation out of service and the high pressure that when again starting, causes moment to reverse osmosis membrane 4 is caused damage.
Claims (1)
1. reverse osmosis unit, be connected with collecting pit (1), high-pressure pump (2) and reverse osmosis membrane (4) by pipeline in turn from A-P, it is characterized in that: be provided with check valve (3) between the influent side of the outlet of high-pressure pump (2) and reverse osmosis membrane (4), the dense water side of reverse osmosis membrane (4) is closed valve (5) and is linked to each other with electronic changing down slowly.
