Technical field
The utility model relates to a kind of device online reverse osmosis membrane in the counter-infiltration system of water treatment being carried out to backwash, belongs to reverse osmosis equipment technical field.
Background technology
Reverse osmosis technology is because itself being applied to the advanced treating field in sewage disposal just more and more to the stalling characteristic of the excellence of pollutant in water.Usual sewage is still difficult in the water quality after conventional biochemical treatment the influent quality requirement reaching counter-infiltration system, and this just proposes challenge to the application of counter-infiltration system, operation and maintenance.At present, in the prior art, reverse osmosis membrane on-line rinsing all adopts membrane surface flushing, and namely flushing water utilizes flow shear to rinse along face.And the obstinate pollution layer that reverse osmosis membrane is in use formed due to long-term accumulated is attached to film surface; high-velocity flow is only relied on to rinse; be difficult to reach the effect as milipore filter backwash normal shutdown in flushing process; and the distinctive membrane structure of reverse osmosis membrane requires that back pressure must not exceed film producer limit value; otherwise; will cause damage to film, therefore can not adopt the back-flushing method of milipore filter.How effective cleaning is carried out to reverse osmosis membrane and become technical problem urgently to be resolved hurrily at present.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of back purge system of reverse osmosis membrane, this back purge system can realize the backwash to reverse osmosis membrane, reaches to improve developing result, delay dirt to the pollution of reverse osmosis membrane, the object extending the cleaning frequency.
The technical scheme solved the problems of the technologies described above is:
A kind of back purge system of reverse osmosis membrane, it comprises elevated tank, backwash inlet pipeline, elevated tank inlet pipeline, elevated tank is placed on the top of reverse osmosis unit main frame, one end of backwash inlet pipeline is connected with elevated tank, the other end of backwash inlet pipeline is connected to the side of reverse osmosis unit main frame, backwash water intaking valve is installed in backwash inlet pipeline, the water inlet that backwash inlet pipeline is connected with reverse osmosis unit main frame is positioned in the reverse osmosis unit main frame chamber sidewall at the reverse osmosis membrane back side, elevated tank inlet pipeline is had to connect elevated tank at the opposite side of reverse osmosis unit main frame, water intaking valve and check-valves are installed in elevated tank inlet pipeline, one end that elevated tank inlet pipeline is connected with reverse osmosis unit main frame is connected on the water producing pipe road of reverse osmosis unit main frame.
The back purge system of above-mentioned reverse osmosis membrane, is provided with liquid level gauge in described elevated tank.
The back purge system of above-mentioned reverse osmosis membrane, the junction on described elevated tank inlet pipeline and water producing pipe road is being produced on the water producing pipe road between water valve and reverse osmosis unit main frame.
The beneficial effects of the utility model are:
The utility model installs elevated tank above reverse osmosis unit main frame, elevated tank is connected with the chamber at the reverse osmosis membrane back side in reverse osmosis unit main frame by backwash inlet pipeline, in backwash inlet pipeline and elevated tank inlet pipeline, respectively by-pass valve control is installed, backwash can be implemented to reverse osmosis membrane by said apparatus.The utility model is in the process of rinsing reverse osmosis membrane, just rinsing and hocketing with backwash, developing result can be significantly improved, reduce the pollution of dirt to reverse osmosis membrane, the cleaning frequency of prolongation reverse osmosis membrane, improve the service life of reverse osmosis membrane, reduce production cost, increase economic efficiency.The utility model have structure simple, control convenient, without the need to increasing power-equipment, advantage that operating cost is low, have good popularizing value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure mark as follows: reverse osmosis unit main frame 1, just rinse inlet pipeline 2, just rinse water intaking valve 3, concentrated water discharge pipeline 4, concentrated water discharge valve 5, water producing pipe road 6, product water valve 7, elevated tank 8, backwash inlet pipeline 9, backwash water intaking valve 10, elevated tank inlet pipeline 11, water intaking valve 12, check-valves 13, liquid level gauge 14.
Detailed description of the invention
Show in figure, reverse osmosis unit main frame 1 is connected with and just rinses inlet pipeline 2, concentrated water discharge pipeline 4, water producing pipe road 6, just rinse in inlet pipeline 2, concentrated water discharge pipeline 4 and water producing pipe road 6 be separately installed with just rinse water intaking valve 3, concentrated water discharge valve 5 and produce water valve 7.Just rinse inlet pipeline 2, concentrated water discharge pipeline 4 and water producing pipe road 6 and can complete just flushing to the reverse osmosis membrane in reverse osmosis unit main frame 1.
Show in figure, the utility model is installed on main reverse osmosis unit main frame 1.The utility model is made up of elevated tank 8, backwash inlet pipeline 9, elevated tank inlet pipeline 11, at backwash inlet pipeline 9, backwash water intaking valve 10 is installed, elevated tank inlet pipeline 11 is installed into water valve 12, check-valves 13, elevated tank 8 is provided with liquid level gauge 14.
Show in figure, elevated tank 8 is placed on the top of reverse osmosis unit main frame 1, the backwash inlet pipeline 9 of elevated tank 8 is connected to the side of reverse osmosis unit main frame 1 by backwash water intaking valve 10, the water inlet that backwash inlet pipeline 9 is connected with reverse osmosis unit main frame 1 is positioned in reverse osmosis unit main frame 1 chamber sidewall at the reverse osmosis membrane back side.Elevated tank inlet pipeline 11 is had to connect elevated tank 8 at the opposite side of reverse osmosis unit main frame 1.
