Description
Technical field
Invention is related to a kind of reverse osmosis (RO) water purifier system, more particularly to one kind no electric pump, and according to raw water quality
And hydraulic pressure is optimizing the reverse osmosis (RO) water purifier system of pure water water quality and waste water discharge rate ratio.
Background technology
Reverse osmosis (RO) water purifier is a kind of equipment extracting pure water by osmosis filtration principle, by carrying out to raw water
Pressurization, using physical principle filtration treatment.Because reverse osmosis membrane aperture is minimum, nearly all microorganism can be filtered out, parasitic
Worm, bacterium, or even fractionated viral etc., so the pure water that RO filters out is not usually required to use disinfection by ultraviolet light again, can be direct
Drink.The pure water capable of direct drinking that existing RO water purifier is produced typically can be stored in a pressure pot, and
Water-bound processed generally comprises the pre-procesor being connected with water service end, is connected water inlet with pre-procesor output end
Magnetic valve and the booster pump being connected with entering water electromagnetic valve output end, the RO membrane cartridge being connected with supercharging pump output terminal.Described
The waste water output end of RO membrane cartridge connects raw water ratio and flushing valve, is then exported waste water by downcomer, RO membrane cartridge
Pure water output end connects high-voltage switch gear, and the output end of high-voltage switch gear connects post active carbon processing meanss.Described rearmounted activity
The output end of charcoal processing meanss connects water purification water tap with two outlet and pressure pot, and pressure pot is used for the pure water after storing filtration.
Existing RO water purifier, in its water-bound processed, easily produces substantial amounts of waste water, filtered wastewater is expelled directly out, and causes
A large amount of wastes of water resource, existing reverse osmosis (RO) water purifier often produces one liter of water purification in pure water filtration stage and typically can arrange
Fall the waste water of more than three times, store the stage into water tank in pure water, because the structure of water tank is so that pure water is protected always
Hold higher hydraulic pressure, particularly water storage last team section, reverse water pressure is increasing, the positive pressure of RO membrane filtration is required more
Height, leads to RO treater to need electric pump to be pressurized, reduces filter water water quality simultaneously, and increase the waste water producing.
In order to reduce waste water discharge rate, many patents are also had to propose to reduce or eliminate waste water, but the patent side of these propositions
Method, typically by increasing new equipment, recycles waste water discharged etc..This brings other problems in practical use simultaneously again
And shortcoming, if desired for increasing electric pump, reduce filter water water quality, the problems such as shorten RO film validity period, so also do not have till now can
To facilitate user, reach applicable business-like water saving RO water purifier product.
Domestic due to each urban area supply tap water be pressed with a larger excursion, from 0.2MPa MPa to
0.4MPa MPa, the impurity containing in water quality and impurity ion content are also different simultaneously, vary widely scope,
So existing RO water purifier is most adds electric pump, before filtration the phase pressurize first raw water, make hydraulic pressure increase to 0.4MPa MPa
Or higher, then start to filter, and also used to water purifier with electric pump in water purifier and make troubles.In addition to reaching more high-purity
The purity of water purification and prolongation RO film validity period, are also disposed at larger the giving up of ratio of a fixation in the flow-limiting valve of RO film wastewater outlet
Water ratio, the wastewater flow rate that this also results in most of RO water purifiers is very big, forms larger waste.
