Description
Technical field
The present invention relates to water-treatment technology field, especially relate to a kind of water inlet structure of reverse osmosis membrane filtration device.
Background technology
Along with the maturation of membrane technique, reverse osmosis membrane skill is used widely in fields such as municipal wastewater, trade effluent, industrial desalinations.Reverse osmosis membrane law technology is filtration medium with reverse osmosis membrane, utilizes the pressure difference of film both sides to drive solution separating.Function due to reverse osmosis membrane removes the impurity contained by former water, and the various impurity that film surface can be retained down covered, and fenestra can be blocked by more tiny impurity, thus reduce the strainability of ultra-filtration membrane.Need regularly to carry out clean to film to address this problem.Chinese patent Authorization Notice No. CN102049198B, authorized announcement date on June 5th, 2013, the patent of invention that name is called " a kind of purging method of reverse osmosis membrane ", provides a kind of method of film being carried out to clean.For olefin production plant process water, recirculated cooling water sewer when carrying out embrane method process, the dirt on the reverse osmosis membrane surface of being caused by organosilicon colloid, polymer organic pollutant and bacterium algae remains is blocked up, the purging method of reverse osmosis membrane comprises the following steps successively: (1) influent side forward rinses, intake from the feed-water end of RO system, the draining of concentrated water discharge end, form water impact by sluicing to reverse osmosis membrane surface, the dirt of removing on reverse osmosis membrane is blocked up; When forward rinses, the flushing flow rate of single film is 2 ~ 10t/h, flush time is 20s ~ 5min, flushing temperature 4 ~ 35 DEG C, pressure are 0.01 ~ 0.5MPa; (2) dense water side back flushing, intakes from the concentrated water discharge end of RO system, feed-water end draining, forms water impact by sluicing to reverse osmosis membrane surface, and the dirt of removing on reverse osmosis membrane is blocked up; When back flushing, the flushing flow rate of single film is 2 ~ 10t/h, flush time is 20s ~ 5min, rinse temperature is 4 ~ 35 DEG C, pressure≤0.1MPa; Influent side forward rinses and the mode of dense water side back flushing adopts pulse lavage, and the flushing cycle of pulse lavage is 0.5 ~ 10s; Influent side forward rinse and dense water side back flushing wash-down water in add Sodium dodecylbenzene sulfonate, acetone or alcohol.This is a kind of matting, and system is wanted out of service and just can be carried out.Not only clean comparatively frequent but also cleaning materials also will process, system operation cost is higher.
Summary of the invention
In order to solve prior art, to there is reverse osmosis system putamina Inner Front End membrane element water production rate large, rear end membrane element water production rate is little, in putamina, the membrane element water production rate of different positions is unbalanced, reverse osmosis membrane needs frequent matting, the technical problem that system maintenance running cost is high, the present invention, a kind of film stacking structure of the direction that intakes by the timed interval conversion membrane stack of setting under membrane stack operation condition is provided, the membrane element of different positions in putamina is made to realize water production rate equilibrium, in the process in conversion water inlet direction, be aided with physics rinse, wash out film surface contaminant in time, reduce fouling membrane degree, improve the rate of recovery, reduce system operation cost.
Technical scheme of the present invention is: a kind of reverse osmosis membrane pile structure of direction-agile of intaking, it comprises water inlet system and membrane stack, membrane stack is connected to into water mother pipe, dense jellyfish pipe and produces jellyfish pipe, water inlet system comprises water intaking valve in parallel and reverse water intaking valve, water intaking valve is connected with the female pipe of water inlet, female pipe of intaking is connected with reverse dense water valve, reverse dense water valve is connected with reversing tube, reverse water intaking valve is connected with dense jellyfish pipe, dense jellyfish pipe is connected with dense water valve, dense water valve is connected with reversing tube, and reversing tube is connected with dense water rising pipe.Commutation water inlet is in turn adopted to run according to the membrane element be connected in putamina along the characteristic that water inlet direction water production rate reduces gradually, eliminate putamina Inner Front End membrane element water production rate large, rear end membrane element water production rate is little, in putamina, the membrane element water production rate of different positions is unbalanced, reverse osmosis membrane needs frequent matting, drawback that system maintenance running cost is high, improve the reverse osmosis system design rate of recovery, reduce the matting frequency, decrease water environment pollution.Normally run without the need to halt system, do not affect normal water supply.
As preferably, water inlet system also comprises intake pump in parallel and water inlet safety valve, and intake pump and water inlet safety valve are connected with water intaking valve and reverse water intaking valve; In operating mode switchover operation, open water inlet safety valve and can reduce low-pressure washing hydraulic resistance loss, water hammer harm when can reduce again valve transfer.
As preferably, dense water rising pipe is parallel with dense water main valve and concentrated water discharge valve, and concentrated water discharge valve is connected with drainage tray; In operating mode switchover operation, when low pressure physical rinses, dense water main valve closedown, concentrated water discharge valve are opened, and discharge the pollutent developed, are conducive to recycling.
As preferably, produce jellyfish pipe and be parallel with product water main valve and produce the defective bleed valve of water, produce the defective bleed valve of water and be connected with drainage tray; Under operation condition, product water water quality is qualified in the discharge of product water main valve, and product water water quality is defective discharges from the defective bleed valve of product water, guarantees to produce quality.
Compared with prior art, the invention has the beneficial effects as follows: by the timed interval alternate wheel swap-in water direction that setting is adjustable, eliminate that putamina Inner Front End membrane element water production rate is large, rear end membrane element water production rate is little, the unbalanced drawback of membrane element water production rate of different positions in putamina, the reverse osmosis system design rate of recovery is high.Reduce the matting frequency, decrease chemical consumption, existing good environmental benefit again reduces system maintenance running cost.Automatic control can be realized, can the free regulating wheel swap-in water timed interval according to water quality situation, flexible and convenient operation.Facility investment is little, reduces running cost.
