Description
Technical field
The utility model is related to water treatment field, more particularly to a kind of water-saving reverse osmosis water purifier.
Background technology
Water-saving reverse osmosis water purifier is a kind of water purifier for applying reverse osmosis technology, and it is than conventional reverse osmosis purified water
Device is economized on water, while not shortening the service life of reverse osmosis membrane.Water-saving reverse osmosis water purifier is a kind of saving type RO water purification
Equipment includes preposition water pretreatment component, booster pump, reverse osmosis membrane filt, water purification storage barrel, rearmounted filter and phase
Answer pipeline and valve.The principle of counter-osmosis device is in the presence of higher than solution osmotic pressure, can not to be passed through according to other materials anti-
Pellicle in permeator and these materials and water are separated.The membrane aperture of reverse osmosis membrane is very small, therefore, it is possible to effective
Ground go water removal in dissolved salts, colloid, microorganism, organic matter.
Patent No. CN201010244513.9 disclosure of the invention a kind of water-saving reverse osmosis water purifier, existing water saving
The principle of type anti-penetration water purifier is usually that raw water enters from water inlet, is pre-processed, increased by preposition water pretreatment component
Press pump supercharging enters back into reverse osmosis membrane filt.The water penetrated from the fenestra of reverse osmosis membrane filt reverse osmosis membrane is pure
Water, flows out water purifier system, it is impossible to which the condensed water penetrated from the fenestra of reverse osmosis membrane is entered into condensed water pressure water storage barrel
Row storage, it is necessary to when filtering is re-started to condensed water, condensed water is arranged to water source tube from discharge outlet by concentrating water discharging valve
Used in downstream water demand utensil in road, condensed water is reasonably and effectively used, improve the service efficiency of condensed water, saved
Can be efficiently.
Although such saving type RO purifier small volume, easy for installation, and can reduce the discharge of condensed water,
And the life-span of filter core in preposition water pretreatment component is improved, the effect of energy-saving and emission-reduction is reached.But the number of times of condensed water backflow is rapid
So increase and increased substantially so that concentrating water concentration, dissolving salt is easily separated out, and is deposited on reverse osmosis membrane surface, reverse osmosis membrane
Service life will substantially shorten, and cause the operating cost of whole water purifier to improve, Consumer's Experience is not good.And if make factory
Family wants to improve the life-span of reverse osmosis membrane, it is necessary to prevent dissolving from saltouing using antisludging agent in preposition water pretreatment component
Go out, and antisludging agent is national health department forbids household water treatment apparatus to use.
The content of the invention
The defect existed for above-mentioned technology, problem to be solved in the utility model is to provide a kind of extension reverse osmosis membrane
The water-saving reverse osmosis water purifier of the water purification energy-saving effect of water purifier is not influenceed while service life.
