Abstract
An energy-saving secondary reverse osmosis device comprises a secondary high pressure pump and a secondary reverse osmosis machine that are sequentially connected via pipes. The utility model is characterized in that the membrane component in the secondary reverse osmosis machine is in a parallel arrangement with a single section, so as to shorten water stream passage and reduce the hydraulic loss of the device, thereby reducing the water inlet pressure and the operation energy consumption of the device.
Description
Technical field
The utility model relates to a kind of two-pass reverse osmosis embrane method system pure water device.
Background technology
It is comparatively general to use the two-pass reverse osmosis film device to make pure water at present, characteristics such as the water of producing water quality is good, environmental protection that it has; But the shortcoming that existing two-pass reverse osmosis embrane method pure water preparation device exists is: because its pattern is analogous to the first-stage reverse osmosis device, thereby the membrane module in the two-pass reverse osmosis device has also adopted the series-parallel arrangement mode of multistage (common is two-section type); Make in the two-pass reverse osmosis device water stream channel long like this, the flow resistance loss is excessive, causes two-pass reverse osmosis device working pressure to increase, and energy consumption is bigger, has reduced the two-pass reverse osmosis plant efficiency.
Summary of the invention
In the utility model, because the water inlet of two-pass reverse osmosis device is the product water of first-stage reverse osmosis device, after it was held back through the first-stage reverse osmosis film, its saltiness and foreign matter content were all quite low, and the two-pass reverse osmosis face seldom may produce the concentration polarization phenomenon; Thereby especially the reverse osmosis membrane assembly in the two-pass reverse osmosis device is arranged to the parallel arrangement of single hop (one-part form), and to shorten water stream channel, reduce hydraulic loss, thereby reduce the system water consumption of two-pass reverse osmosis device, improve the efficient of two-pass reverse osmosis device.
Technical solution of the present utility model is: in the two-pass reverse osmosis device that the secondary high-pressure pump that is linked in sequence with pipeline, two-pass reverse osmosis device are formed, especially the reverse osmosis membrane assembly in the two-pass reverse osmosis device is arranged to the parallel arrangement of single hop (one-part form).
The utility model is arranged to the parallel arrangement of single hop with the membrane module in the two-pass reverse osmosis device, shortened the water stream channel of membrane module in the two-pass reverse osmosis device, effectively reduce the flow resistance of device, thereby reduced the working pressure of two-pass reverse osmosis device, reduced device system water consumption.Facts have proved that under identical water production rate condition, the utility model can reduce the intake pressure of device, thereby reduced the system water consumption of two-pass reverse osmosis device.
Description of drawings
Accompanying drawing is an overall structure synoptic diagram of the present utility model.
Embodiment
Composition structure of the present utility model such as accompanying drawing, the product water 1 that obtains from the first-stage reverse osmosis device is as the water inlet of two-pass reverse osmosis device, by water inlet pipe 2, send into secondary high-pressure pump 3, after 3 pressurizations of secondary high-pressure pump, deliver to two-pass reverse osmosis device 5 by secondary high-pressure pump outlet pipe 4, after two-pass reverse osmosis device 5 was handled, the pure water of output was by 8 one-tenth secondary pure water of pipeline, 9 outer confessions; The dense water of two-pass reverse osmosis device effluxes dense water 7 by 6 one-tenth in pipeline.In the utility model, special in the reverse osmosis membrane assembly 5-1 in the two-pass reverse osmosis device 5,5-2 and 5-3 are arranged to the parallel arrangement of single hop (one-part form).
Below to one the cover 20m
3/ h two-pass reverse osmosis device example describes.
In the two-pass reverse osmosis device, adopt three six core membrane modules.In the coventional type two-pass reverse osmosis device, three reverse osmosis membrane assemblies adopt two sections series-parallel connection to arrange (two-section type), and in the utility model, three reverse osmosis membrane assemblies adopt the parallel arrangement of single hop (one-part form); Concrete result of implementation is as follows:
By above table as seen, under the identical water production rate prerequisite of two-pass reverse osmosis device, the utility model can significantly reduce the intake pressure of two-pass reverse osmosis device, thereby reduces the system water consumption of two-pass reverse osmosis device, save energy.
