Abstract
The invention discloses a high efficiency reverse osmosis water purifying device that includes pressure pump, pretreatment filter, refine filter, reverse osmosis main machine. Its features are that the pretreatment filter is connect in series with the sub-acidity and strong acidity positive ion resin exchange columns; the latter is connected in series with the pH regulating system used to regulate the pH value to 8.5-12 for the water. The invention has the advantages of over 95% deprivation ratio for weak ionization substance, over 90% pure water recovery ratio, low cost, compact structure, low operating cost.
Description
Technical field
The present invention relates to a kind of industrial sectors such as semi-conductor, pharmacy, biotechnology, steam power plant and nuclear plant that are used for and prepare the efficient seppage-resisting water purifying machine that pure water is used.
Background technology
The existing report of 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.
Summary of the invention
The object of the present invention is to provide a kind of former water rate of recovery can reach more than 90%, 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.
Technical scheme of the present invention 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 present invention 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 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 one embodiment of the invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment:
With reference to accompanying drawing: former water is through topping-up pump 1, pretreatment filters 2, the pretreatment filters of present embodiment is a double decker filter, enter acidulous cation resin exchange column 3, remove nearly all non-hydrogen cation with strong acidic ion resin exchange column 4, it is acid that water outlet after the processing shows, and through pH value regulation system 5 pH value of water is adjusted to 8.5-12, again after accurate filter 6 filters, pump into reverse osmosis main frame 8 preparation pure water by high-pressure pump 7, be transported at last in the pure water case 9.Resin after the exchange enters resin regeneration system 10 and regenerates.
The 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%.
