Abstract
The invention discloses a reverse osmosis water purifier. The reverse osmosis water purifier comprises a water feeding pipe, a microfiltration system and a reverse osmosis unit. The water feeding pipe, the microfiltration system and the reverse osmosis unit are orderly connected by water inlet pipes. A reverse osmosis film in the reverse osmosis unit divides the reverse osmosis unit into a pure water zone and a concentrated water zone. A pure water outlet is arranged in the pure water zone. A water inlet and a concentrated water outlet are arranged in the concentrated water zone. The reverse osmosis water purifier also comprises return pipe lines, a pressure water storage tank and a pipe control unit. The concentrated water outlet of the reverse osmosis unit is connected to the water inlet pipes by the return pipe lines. The water inlet pipes, the reverse osmosis unit and the return pipe lines form a circulating pipe line. The pressure water storage tank is arranged on the circulating pipe line. The pipe control unit controls water flows in the circulating pipe line. The microfiltration system comprises first-stage compressed PP cotton, second-stage granular activated carbon and third-stage compressed activated carbon. The reverse osmosis water purifier prevents reverse osmosis membrane obstruction, effectively prolongs a pre-treatment filter core service life, has stable cycling water flow stability, has a stable structure and greatly reduces a use cost.
Description
Technical field
The present invention relates to a kind of water purifier, be specifically related to a kind of anti-penetration water purifier.
Background technology
In prior art, the quantity discharged of dense water normally base runoff, according to the design requirements of film, raw water quality is harder, the frequency of then rinsing is shorter, and spent wash-down water is more, otherwise, raw water quality is softer, and the frequency of flushing is longer, and spent wash-down water is fewer.Further, owing to not carrying out the device of water quality monitoring (WQM) to former water, the discharge of dense water mainly contains two modes: 1 is the form adopting base runoff, and that is, reverse osmosis membrane is while filtered water, and dense water synchronously can eject through the device of a base runoff; 2 is the forms adopting regular discharge, and namely arrange a time switch at dense water end (W.E.), reverse osmosis membrane often works the regular hour, and time switch can start, and is gone out by dense water.In prior art, the shortcoming of above-mentioned two kinds of modes is: when water quality is softer, and discharge number of times is too much, discharge hypervolia causes water resource waste.The shortcoming of current anti-penetration water purifier structure is, through waste water ratio discharge dense water through pretreatment unit process, though its foreign matter content difference compared with pure water is larger, but its water quality still higher than or be equivalent to ordinary tap water (mainly mineral concentration is higher than tap water), then can only drain with the form of waste water and cause huge waste herein.Often make 1 cubic metre of pure water under normal circumstances will to drain the dense water of 4 cubic metres; This structure also needs independently reverse osmosis membrane cleaning procedure in addition, the water that flushing process uses controls also to drain as waste water by scouring electromagnetic valve, while waste water source, also increase the working load of pretreater, affect the working life of filter core in pretreater.
Summary of the invention
According to above the deficiencies in the prior art, the present invention proposes a kind of anti-penetration water purifier, can not waste discharge, saving water resource, can increase the working life of filter core simultaneously.
To achieve these goals, the technical scheme that the present invention takes is:
A kind of anti-penetration water purifier, comprise the water service pipe, microfiltration systems and the reverse osmosis units that are connected successively by suction culvert, reverse osmosis units is divided into pure water district and dense pool by the reverse osmosis membrane of reverse osmosis units inside, pure water district is provided with pure water outlet, dense pool is provided with water-in and dense water out, also comprise return line, pressure water storage tank and pipeline control unit, the dense water out of reverse osmosis units is connected on suction culvert by return line; Described suction culvert, reverse osmosis units and return line composition circulation line; Described pressure water storage tank is arranged on circulation line, the current in pipeline control unit controlled circulation pipeline, and described microfiltration systems comprises first step compression PP cotton, second stage granulated active carbon and third stage extruded activated carbon.
Preferably, the suction culvert of described reverse osmosis units is also connected with topping-up pump.Be provided with entering water electromagnetic valve between described microfiltration systems and reverse osmosis units, be also provided with the pressure relief regulating device be made up of pressure regulator valve and reverse checkvalve between described entering water electromagnetic valve and described dense water lines, this pressure relief regulating device is connected to topping-up pump feed-water end.
Preferably, the pipeline between described reverse osmosis units and pressure water storage tank is provided with TDS probe, and described dense water lines is provided with magnetic valve, and described magnetic valve controls the time of concentrated water discharge and the amount of discharge according to the data that described TDS probe monitors.
Preferably, described pressure water storage tank comprises body, capping and airbag; Described lidstock is fixed on body; Described body is respectively equipped with water-in and water outlet; Described airbag is arranged in body.
Preferably, low-tension switch is provided with between described microfiltration systems and reverse osmosis units.
Preferably, the infiltration aperture of described reverse osmosis membrane is 0.0001 micron, and the diameter of described reverse osmosis membrane is 7-9 centimetre.
Beneficial effect of the present invention is: anti-penetration water purifier provided by the present invention not waste discharge, has both saved water resources, and turn avoid the installation of wastewater discharge pipe, and carrys out the pattern of dynamic conditioning flushing according to the value that TDS probe is monitored.Without the need to arranging additional reverse osmosis membrane cleaning procedure, and only need when each water processed starts by making to flow through the larger flushing of tangential flow velocity realization to reverse osmosis membrane of reverse osmosis membrane surface current, the blocking of reverse osmosis membrane can be prevented, effectively extend again the work-ing life of preprocessing filter element.The circulating water flow of this anti-penetration water purifier is stablized, and anti-penetration water purifier Stability Analysis of Structures, greatly reduces use cost.
