Abstract
The utility model discloses a high-efficiency reverse osmosis water purifying machine, which comprises a booster pump, a preprocessing filter, a fine filter and a reverse osmosis host machine. The utility model is characterized in that the back of the preprocessing filter is serially connected with a weak-acid cation resinous exchange column and a strong-acid cation resinous exchange column which is serially connected with a pH adjusting system, the pH adjusting system adjusts the pH of water to 8.5 to 12, and then the water gets into the fine filter and the reverse osmosis host machine. The utility model uses weak-acid cation exchange resin and the strong-acid cation exchange resin to eliminate almost all the non-hydrogen cation, which remarkably decreases cation deposition on films. Simultaneously, reverse osmosis films operate under high pH, which also remarkably decreases silicon deposition and biological deposition and realizes that the eliminating rate of weak-ionization matter is larger than ninety-five percent and the recovery rate of pure water is larger than ninety percent. Besides, the whole machine is low in equipment costs, compact in structure and low in operation expense.
Description
Technical field
The utility model relates to a kind of efficient seppage-resisting water purifying machine that preparation pure water such as semi-conductor, pharmacy, food, biology, metallurgy, steam power plant and nuclear plant are used that is used for.
Background technology
The existing report of existing reverse osmosis water purification machine, as the automatic water purification machine of Chinese patent 93220895.9 disclosed a kind of reverse osmosiss, 99210374.6 disclosed two-pass reverse osmosis water purification machine etc., but existing reverse osmosis water purification machine exists reverse osmosis membrane knot calcium dirt, silicon dirt or biological fouling or its combination fouling, has had a strong impact on the production efficiency of water purification machine and the work-ing life of reverse osmosis membrane; Reverse osmosis water purification machine commonly used at present has only 60-70% to the organic efficiency of former water, and top efficiency generally is no more than 75%, also to often clean reverse osmosis membrane, and also low to weakly ionized matter (for example carbonic acid gas, metasilicic acid etc.) decreasing ratio; Reverse osmosis water purification machine of other external report then exist complex structure, price height, volume big, be not easy to shortcomings such as transportation, Installation and Debugging.
The utility model content
The purpose of this utility model is to provide a kind of former water rate of recovery can reach more than 90%, and structure is simple, reasonable price, little, weakly ionized matter (for example carbonic acid gas, the metasilicic acid etc.) reverse osmosis water purification machine that decreasing ratio is high of volume.
The technical solution of the utility model is: comprise topping-up pump, pretreatment filters, accurate filter, reverse osmosis main frame, it is characterized in that the pretreatment filters back is in series with acidulous cation resin exchange column and strong acidic ion resin exchange column, strong acidic ion resin exchange column back is serially connected with the PH regulation system, the PH regulation system enters accurate filter, reverse osmosis main frame after the pH value of water is adjusted to 8.5-12 again.
Described weakly acidic cation-exchange resin and storng-acid cation exchange resin can be located in the same cation exchange tower, also can be located in two placed in-line exchange columns.
Described weakly acidic cation-exchange resin and storng-acid cation exchange resin are Hydrogen.
Described pretreatment filters can be double decker filter, also can be high efficiency filter or more medium filter or activated charcoal filter and other conventional pretreatment unit.
The utility model is because process weakly acidic cation-exchange resin and storng-acid cation exchange resin have been removed the non-hydrogen cation of nearly all (greater than 99%), so significantly reduced reverse osmosis membrane cationic fouling (calcium dirt, barium dirt, strontium dirt, magne-scale, iron dirt etc.); Because reverse osmosis membrane moves, significantly reduced silicon dirt or biological fouling, and weakly ionized matter (for example carbonic acid gas, metasilicic acid etc.) decreasing ratio under high pH value improves greatly also under high pH value.The utility model pilot experiment pure water rate of recovery can reach more than 90%, and weakly ionized matter (for example carbonic acid gas, metasilicic acid etc.) decreasing ratio is greater than 95%; And the whole set equipment cost is low, structure is tight, working cost is low.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing: former water is through topping-up pump 1, pretreatment filters 2, the pretreatment filters of present embodiment is double decker filter, enter acidulous cation resin exchange column 3, remove nearly all non-hydrogen cation through strong acidic ion resin exchange column 4 again, it is acid that water outlet after the processing shows, through pH value regulation system 5 pH value of water is adjusted to 8.5-12, after accurate filter 6 filters, pump into reverse osmosis main frame 8 preparation pure water again, be transported at last in the pure water case 9 by high-pressure pump 7.Resin after the exchange enters resin regeneration system 10 and regenerates.
