Description
Technical field
The invention belongs to purifier technical fields, and in particular to a kind of purifier and its application method.
Background technology
Water is Source of life, and daily life be unable to do without water, the body of the quality and people of Drinking Water water quality
Health is closely related.By for many years, the publicity of the drinking-water and health knowledge of cycle and universal, importance of the people to water purifier
Gradually understand, and recognize influence of the quality of drinking water to health, to more pay attention to safe drinking water, this is water purifier product
Production provide very big market foreground.Household water purifier has had 95% family to open in western developed countries such as Europe, the United States
Begin to use, and at home, family's utilization rate is less than 5%, therefore water purifier also has vast development space at home.
In purifier, especially RO films purifier, be a kind of collection micro-filtration, absorption, ultrafiltration, reverse osmosis, ultraviolet-sterilization,
The technologies such as ultrapureization in one, tap water is converted into the device of ultra-pure water.The core element of reverse osmose pure-water unit is
Reverse osmosis (RO) film.The pure water that reverse osmosis water purification machine is made is fresher relative to bottled water, much cleaner, safer, therefore it
Purposes it is very extensive.Its operation principle is to apply certain pressure to water, makes hydrone and the mineral matter element of ionic state
By reverse osmosis membrane, and the most inorganic salts (including heavy metal) being dissolved in water, organic matter and bacterium, virus etc. are miscellaneous
Matter can not penetrate reverse osmosis membrane, and the condensed water to make the pure water penetrated and can not penetrate is stringent to be separated.It is reverse osmosis
Aperture on film only has 0.0001 micron, therefore is used for multiple times, and the surface on RO films has many remaining harmful substances, RO films
Main pollution modes have：
One, germ contamination, caused by influence to have：Salt rejection rate may be decreased, system pressure drop obviously increases, system water yield is bright
It is aobvious to reduce.
Two, sulfuric acid calcium contamination, caused by influence to have：Salt rejection rate is substantially reduced, system pressure drop slightly or moderately increases, system
Water yield is in a slight decrease.
Three, organic matter precipitate, caused by influence to have：Salt rejection rate may be decreased, system pressure drop gradually rises, system water yield
It continuously decreases.
Four, oxide (iron, nickel, copper) pollute, caused by influence to have：Salt rejection rate is decreased obviously, system pressure drop is significantly raised,
System water yield is substantially reduced.
Five, inorganic salt precipitates pollute, caused by influence to have：Salt rejection rate is decreased obviously, system pressure drop increases, system produces water
Amount slightly drops.
Six, various colloids (iron, organic matter and colloidal silica) pollution, caused by influence to have：Salt rejection rate is slightly by low, system pressure
Drop slightly rises, system water yield gradually decreases.
Therefore it is necessary to will be to RO film periodic cleanings.Existing purifier is usually directly to be rinsed with waste water (condensed water), this
The effect unobvious of kind cleaning way, and inefficiency, are often not achieved expected effect.Also compared using condensed water cleaning
Waste water resource is even filtered for multiple times if this part water can utilize again by primary, it will water resource is saved, and
Improve the ratio of clean water and waste water.There is also the relatively low disadvantage of production water speed, existing water purification cartridges for existing purifier
Although setting inside is designed with water tank, when the water in water tank uses up part production water again, in the big place of amount of drinking water
(such as library of colleges and universities) often has the phenomenon that supply falls short of demand, therefore the production water speed for improving purifier is extremely urgent.

10. a kind of application method of purifier as described in any one of claim 1 to 9, which is characterized in that the user
Method includes the following steps：
Step 1, the preparation of pure water：Water intake ball valve is opened, and water is flowed by water intake ball valve in inlet pipeline, then passes through level-one
Filter core is completed to filter for the first time, removes and is more than 5 microns of floating materials and particulate matter in water, then pass through two level filter core, absorption removes
Fall heterochromatic peculiar smell in water, the chlorine residue in water improves the mouthfeel of water, using three-level filter core, removes miscellaneous more than 1 micron in water
Matter, filtered water enter in RO films, and by the pressurization of booster pump, hydrone passes through RO films, it is miscellaneous to filter out heavy metal ion etc.
Matter molecule, filtered water flow into water tank by check valve, and the pressure of water tank reaches the setting value of high-voltage switch gear, into water polo
Valve is closed, and the preparation of pure water is completed；
Step 2, the cycle of waste water：Scouring electromagnetic valve is in off state, remaining after pressurized filtering to contain a huge sum of money in RO films
The water for belonging to ion and other impurities molecule is waste water, and waste water enters waste pipe, flows into the first access, by the on the first access
One check valve flows into inlet pipeline, this effluent part for flowing into inlet pipeline is completed second according to the method described in step 1
It filtering, the water after secondary filter recycles once according to the method described above, completes third time and filters, after filtering three times, flushing electromagnetism
Valve is opened, and filtered waste water is discharged by wastewater outlet three times；
Step 3, the flushing of RO films：Water intake ball valve is closed, and scouring electromagnetic valve is opened, and washes film solenoid valve opening, pure in water tank
Water flows into alternate path, passes through third check valve successively, washes film solenoid valve and enter RO film water inlet ends, into the pure water rinsing of RO films
Fall to be attached to the heavy metal ion and other impurities on RO film outer surfaces, and carries the spot rinsed out and pass through scouring electromagnetic valve stream
It is discharged through wastewater outlet, and by wastewater outlet.
