Description

A kind of without bucket formula water saving water purifier
Technical field
The present invention relates to a kind of water saving water purifier, relate in particular to the water purifier that adopts reverse osmosis membrane and nanofiltration membrane, belong to water purification field.
Background technology
Because reverse osmosis membrane or nanofiltration membrane have very high filtering precision, can effectively remove the various hazardous contaminants such as microorganism, pesticide residue such as fine particulates in water, organism, soluble salts, heavy metal ion, bacterium, virus, at present, adopt the water purifier of reverse osmosis membrane or nanofiltration to be generally used, are particularly useful for family tap water is further processed, but common reverse osmosis water purification machine or nano-filtration water purifier in use there are following deficiency and defect:
(1) waste water ratio is higher, does not economize on water.According to the Penetration Signature of reverse osmosis membrane, too high and cause concentration polarization for fear of film surface salt concn, must strictly control the rate of recovery of reverse osmosis membrane, the rate of recovery of general single reverse-osmosis membrane element will be controlled at below 15%, and such 85% water is discharged with the form of dense water.The waste water ratio of general household reverse osmosis film is 3:1, even up to 5:1, produces 1 glass of pure water, 3 glasss to 5 glasss waste water of output, and along with the development of using film to pollute, the permeant flux of film reduces gradually, and waste water ratio raises gradually.If these " waste water " are not used, very large water resource waste will be caused.Therefore, the rate of recovery of raising reverse osmosis water purification machine is to need at present the difficulties of solution.1., force to reduce the dense water yield common solution has:, or adopt dead-end filtration pulse cleaning etc., this method must shorten the life-span of reverse osmosis membrane, and affects effluent quality.2., cycling utilization of wastewater, dense water is returned to water inlet pipe, or injects running water pipe.As patent CN 201737789 U, this method causes equally dense water to circulate in RO machine and cannot discharge, inject running water pipe and can not guarantee that water purification machine guarantees to use domestic water leading in water process processed, so these class methods can not be dealt with problems to essence.Therefore the generation of reverse osmose pure-water organic waste water is inevitable, and realizing non-wastewater discharge is impossible substantially, the wastewater flow rate of can only taking measures to reduce.
(2) pressure water storage barrel secondary pollution problem.Because reverse osmosis membrane filtration precision is high, thereby unit membrane area water production rate is lower, just current cost is higher in reverse osmosis membrane application, therefore in the process structure of traditional classical reverse osmosis water purification machine, needs to be equipped with pressure water storage barrel and is used in conjunction with the requirement to the water outlet water yield while meeting application abortion water yield reverse osmosis membrane assembly (50~100GPD reverse osmosis membrane assembly).Pressure water storage barrel is comprised of plastic cement or metal shell and food grade rubber liner, and in bucket, minute upper and lower two portions, fill water above, below inflation.During pure water mechanism water, the water making is stored in rubber liner, stops water processed after reaching certain pressure; During water, pressure pot extrudes water from inner bag, and the pressure in bucket is lower than after to a certain degree, and high-voltage switch gear is opened, and water purification machine starts water processed again.Just because of pressure pot stores the pure water of making, the volume of the bucket of one general configuration is often greater than single usage quantity, cause made pure water meeting overstand, secondly also have the quality problems of rubber liner itself and aging, with regard to being difficult to, avoid the rubber liner in pressure pot in use may occur the secondary pollution problems such as microbial growth, nitrite exceed standard, rubber smell like this.
And at present commercially available without bucket formula reverse osmosis water purification machine, most reverse osmosis membranes that only adopt Dan Zhi great flux, cancel pressure water bucket, but single reverse osmosis membrane is not put forward the high yield water rate of recovery, does not solve the problem that waste water ratio is large.
(3), being not suitable for old man, pregnant woman and child on long-term drinks.Water purification machine is reverse osmosis water purification machine especially, because filtering accuracy is high, the ratio of desalinization of general reverse osmosis membrane is all more than 95%, almost remove all soluble salts and to human body beneficial mineral matter, long-term drinking pure water, can reduce immune function of human body, pure water has stronger solvability, easily causes the calcareous loss that waits nutrient in body.The elderly who particularly suffers from cardiovascular disorder, diabetes, this water of the more unsuitable long-term drinking of pregnant woman and children.
(4), can not meet household kitchen water and drinking water simultaneously.Common reverse osmosis water purification machine product discharge is less, even outfit pressure water storage barrel, can not meet household kitchen water amount and drinking water amount simultaneously, the middle resident's family life of national standard < < life of urban resident water supply standard > > (GB/T 50331-2002) of issuing according to the Ministry of Construction is daily water consumption investigation statistics table data per capita, daily water consumption kitchen water is 21.38~29.6L/ (d people) per capita, drinking the water yield is 1.8~3L/ (d people), account for respectively 21.5~24.8% of daily water consumption per capita, 1.8~2.2%.From statistic data, can find out that drinking the water yield only accounts for a seldom part, and also have the water yield for kitchen use of important requirement larger to water quality, simple reverse osmosis water purification machine can not meet the water yield for kitchen use, need to additionally purchase central water purifier or the kitchen water purifier of large flow.
