Abstract
The utility model discloses an online recovery device for reverse osmosis concentrated water. In the online recovery device for the reverse osmosis concentrated water which is formed by connecting a high-pressure pump and a concentrated water reverse osmosis device in sequence by a pipeline, a produced water return pipe is specifically led out from a water production pipe of the concentrated water reverse osmosis device so that the produced water enters a water inlet pipe of the high-pressure pump and is mixed with the reverse osmosis concentrated water; the mixed water enters the concentrated water reverse osmosis device after be pressurized by the high-pressure pump, so that part produced water of the concentrated water reverse osmosis device is circulated in the body of the concentrated water reverse osmosis device; therefore, the impurity content of the inlet water of the concentrated water reverse osmosis device is effectively reduced, the membrane surface flow rate in the concentrated water reverse osmosis device is improved, inlet water pollutants are not easily deposited on the membrane surface of the concentrated water reverse osmosis device, the pollution rate of a reverse osmosis membrane surface is reduced, and the service life of the concentrated water reverse osmosis device is prolonged.
Description
Technical field
The utility model relates to a kind of reverse osmosis concentrated water online recycling device.
Background technology
At present, for the reverse osmosis concentrated water of original discharge is recycled, and adopt, dense water is sent into the technology that dense water counter-osmosis device is further processed, obtained certain application.But because the water inlet of dense water counter-osmosis device is reverse osmosis concentrated water, its water inlet foreign matter content is higher, easily causes the obstruction of dense water counter-osmosis device, causes dense water counter-osmosis device degradation, affects the work-ing life of dense water counter-osmosis device.
Summary of the invention
The purpose of this utility model is to provide a kind of reverse osmosis concentrated water online recycling device of difficult pollution, to reduce the obstruction of dense water counter-osmosis device, reduces the speed of dense water counter-osmosis device degradation, the work-ing life of improving dense water counter-osmosis device.
Technical solution of the present utility model is: at the high-pressure pump being linked in sequence with pipeline, dense water counter-osmosis device, form in reverse osmosis concentrated water online recycling device, special from the water producing pipe of dense water counter-osmosis device, draw and pick out a product water return line, enter in high-pressure pump water inlet pipe; This product water return line is provided with control valve, for regulating the water production rate of backflow.
The beneficial effects of the utility model are, due to being produced to water, the part of dense water counter-osmosis device is back to high-pressure pump import, mix by high-pressure pump and pressurize with reverse osmosis concentrated water, enter again dense water counter-osmosis device, make like this part product water of dense water counter-osmosis device circulate in its body, thereby effectively reduce dense water counter-osmosis device water inlet foreign matter content, and improved the crossflow velocity in dense water counter-osmosis device, make to be difficult for the face deposition at dense water counter-osmosis device into water pollutent, reduced the speed of reverse osmosis membrane surface pollution, thus the work-ing life of having improved dense water counter-osmosis device.
Accompanying drawing explanation
Accompanying drawing is the utility model overall structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As accompanying drawing; Reverse osmosis concentrated water (1) enters high-pressure pump (3) by pipeline (2), after high-pressure pump (3) pressurization, by pump discharge pipe (4), deliver to dense water counter-osmosis device (5), pressurized water is after dense water counter-osmosis device (5) is processed, the water purification of output (7) enters subsequent process by water producing pipe (6), and the dense water after dense water counter-osmosis device (5) is processed is disposed to collection box (9) by delivery pipe (8).In the utility model, especially from the water producing pipe (6) of dense water counter-osmosis device (5), draw and pick out a product water return line (10), enter on the inlet pipeline (2) of high-pressure pump (3), it is mixed with reverse osmosis concentrated water (1), after high-pressure pump (3) pressurization, by high-pressure pump outlet conduit (4), enter dense water counter-osmosis device (5) again, thereby the part that makes dense water counter-osmosis device (5) is produced water and is circulated in its body, effectively reduce dense water counter-osmosis device (5) water inlet foreign matter content, and improved the crossflow velocity of dense water counter-osmosis device (5), reduced the speed of its film surface pollution, improved the work-ing life of dense water counter-osmosis device (5).
Claims (2)
1. a reverse osmosis concentrated water online recycling device, comprise the reverse osmosis concentrated water online recycling device that the high-pressure pump (3) that is linked in sequence with pipeline and dense water counter-osmosis device (5) form, it is characterized in that from the water producing pipe (6) of dense water counter-osmosis device (5), draw and pick out a product water return line (10), after mixing with reverse osmosis concentrated water, enter after high-pressure pump (3) pressurization, enter again dense water counter-osmosis device (5), make like this part product water of its dense water counter-osmosis device (5) circulate in dense water online recycling device body.
According to claim 1 the dense water counter-osmosis device in reverse osmosis online recycling device to produce water return line (10) upper, be provided with control valve, for regulating dense water counter-osmosis device to produce the quantity of reflux of water.
