Abstract
低操作压力反渗透装置，包括以管道顺序连接的高压泵和反渗透器组成的反渗透装置，其特征是将反渗透器中的膜组件布置成单段并联式排列；同时在反渗透器浓水管上引接出部分浓水，回流至高压泵前，在该浓水回流管上设有调节阀，用于调节回流的浓水量。在本实用新型中，由于采用了反渗透组件单段并列式排列和部分浓水回流相结合，使得反渗透装置中的反渗透膜在不产生浓差极化的前提下，降低了反渗透装置的操作压力，这样也就降低了反渗透膜的压密系数，有效延缓了反渗透膜性能的衰减，从而延长了反渗透装置的使用寿命。
A low operating pressure reverse osmosis device, including a reverse osmosis device composed of a high-pressure pump and a reverse osmosis device connected in sequence in pipelines, is characterized in that the membrane modules in the reverse osmosis device are arranged in a single-stage parallel arrangement; Part of the concentrated water is led out from the water pipe and returns to the high-pressure pump. A regulating valve is provided on the concentrated water return pipe to adjust the amount of concentrated water returned. In the utility model, due to the combination of single-stage parallel arrangement of reverse osmosis components and partial concentrated water backflow, the reverse osmosis membrane in the reverse osmosis device can reduce the concentration polarization of the reverse osmosis device without generating concentration polarization. This reduces the pressure coefficient of the reverse osmosis membrane, effectively delaying the attenuation of the performance of the reverse osmosis membrane, thereby prolonging the service life of the reverse osmosis device.
Description
Technical field
The utility model relates to a kind of reverse osmosis membrane legal system pure water device.
Background technology
It is comparatively general at present to use reverse osmosis membrane apparatus to make pure water, characteristics such as water quality treatment wide ranges, effluent quality are good, environmental protection that it has; But the shortcoming that existing reverse osmosis membrane pure water preparation device exists is, because reverse osmosis unit produces for preventing the concentration polarization of counter-infiltration face, membrane module in the reverse osmosis unit adopts multistage tandem arrangement mode, make in the reverse osmosis unit water stream channel long like this, hydraulic loss is excessive, thereby reverse osmosis unit needs higher operating pressure, could guarantee the runnability of reverse osmosis unit.Higher reverse osmosis unit operating pressure will cause the reverse osmosis membrane coefficient of compaction bigger, cause that the reverse osmosis membrane performance decay increases, thereby influence the service life of reverse osmosis unit.
Summary of the invention
The utility model is arranged to the parallel arrangement of single hop with the reverse osmosis membrane assembly in the reverse osmosis unit, to shorten water stream channel, reduces the hydraulic loss of device, thereby reduces the operating pressure of reverse osmosis unit; Simultaneously, certain flow rate is arranged, reverse osmosis concentrated water is carried out partial reflux, make it,, improve the counter-infiltration crossflow velocity, prevent the generation of counter-infiltration face concentration polarization to increase reverse osmosis concentrated discharge in the reverse osmosis unit body-internal-circulation for guaranteeing the counter-infiltration face.
Reverse osmosis unit of the present utility model is: in the reverse osmosis unit that the high-pressure pump that is linked in sequence with pipeline, counter-osmosis device are formed, especially the reverse osmosis membrane assembly in the counter-osmosis device is arranged to the parallel arrangement of single hop; Simultaneously on the dense water pipe of counter-osmosis device, draw and pick out the dense water of part, be back to high-pressure pump before; On this concentrate recirculation pipe, be provided with control valve, be used to regulate the concentrate recirculation amount.
Reverse osmosis unit in the utility model, owing to adopted arrangement of reverse osmosis membrane assembly single hop block form and part concentrate recirculation to combine, make reverse osmosis membrane in the reverse osmosis unit under the prerequisite that does not produce concentration polarization, effectively reduce the reverse osmosis unit operating pressure, so also just reduced the coefficient of compaction of reverse osmosis membrane, delay the decay of reverse osmosis membrane performance, thereby prolonged the service life of reverse osmosis unit.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment
Composition structure of the present utility model such as accompanying drawing; The pretreated water 1 that obtains from pretreatment system is as former water, by water inlet pipe 2, send into high-pressure pump 3, after high-pressure pump 3 pressurizations, deliver to counter-osmosis device 5 by high-pressure pump outlet 4, after counter-osmosis device 5 was handled, the pure water of output was outer for pure water 7 by 6 one-tenth in pipeline, and the dense water of output drains into dense pond 9 by delivery pipe 8; In the utility model, especially reverse osmosis module 5-1,5-2 in the counter-osmosis device 5 and 5-3 are arranged to the parallel arrangement of single hop; Simultaneously draw a concentrate recirculation pipe 10 in dense water pipe 8, be back to high-pressure pump 3 former water 1 preceding and that pipeline 2 is come in and mix, mixing water enters high-pressure pump 3 by pipeline 2; Concentrate recirculation pipe 10 is provided with control valve, regulates the dense water yield that refluxes as required.
Below with a cover 15m
3/ h reverse osmosis unit is that example describes:
Reverse osmosis unit adopts three six core membrane modules.Three reverse osmosis membrane assemblies of plain edition reverse osmosis unit adopt two sections arranged in series (being that 2-1 arranges).Three reverse osmosis membrane assemblies adopt the parallel arrangement of single hop in the utility model, simultaneously an amount of reverse osmosis concentrated water are refluxed.Concrete result of implementation is as follows:
By above table as seen, under the identical aquifer yield prerequisite of device, the utility model can obviously reduce the operating pressure of device, operating pressure reduction along with reverse osmosis unit, the coefficient of compaction of reverse osmosis membrane reduces, the decay that is reverse osmosis membrane performance reduces, and has so just effectively prolonged the service life of reverse osmosis unit.
