Description
Technical field
The utility model belongs to water-treatment technology field, particularly RO reverse osmosis membrane water-purifying machine.
Background technology
Along with people's living standard improves, health is more and more paid attention to, also more and more higher to the requirement of tap water.So RO reverse osmosis membrane directly drink machine is used and given birth to, allow people drink healthy, safe water purification.
The RO reverse osmosis membrane is directly drunk machine and is RO reverse osmosis membrane water-purifying machine again, the English full name of RO is: Reverse Osmosis is reverse osmosis, RO reverse osmosis membrane water-purifying machine is to utilize principle of reverse osmosis to carry out water treatment, be provided with the reverse osmosis membrane filter cylinder in the water-purifying machine, the reverse osmosis membrane filter core is housed in the filter cylinder, under certain pressure, water molecules can pass through the RO film, and impurity such as the inorganic salt in the water, heavy metal ion, organism, colloid, bacterium, virus can't see through the RO film, come out thereby make a part of water see through the RO membrane sepn, the water that does not see through forms dense water because of solute increases.The reverse osmosis membrane water-purifying machine is used for seawater and brackish water desalination in early days, and industrial circles such as oiler feed, wastewater treatment are introduced in civil area in recent years.
Though the reverse-osmosis treated technology has many good qualities, it has produced a part of dense water producing water purifying simultaneously, and the water purification/waste water ratio of RO film is 1: 4 usually, that is to say, after process-inferior purification was filtered, the dense water of generation was about 4 times of water purifying.
Existing reverse osmosis membrane water-purifying machine is a core with the reverse osmosis membrane filter cylinder, be provided with multistage pre-treatment filter cylinder before the reverse osmosis membrane, be provided with one-level aftertreatment filter cylinder after the reverse osmosis membrane filter cylinder, because reverse osmosis membrane needs certain hydraulic pressure to work, so water-purifying machine must install special topping-up pump additional, topping-up pump is controlled by high-voltage switch gear.
Existing reverse osmosis membrane water-purifying machine all is the concentrated water discharge type, dense water after primary purification is soon filtered is used as direct discharging of waste water and is fallen, this a kind of really very big waste, particularly small-sized family expenses, commercial water-purifying machine, its former water is tap water, the water quality of filtering the dense water that produces through primary purification is not poorer than former water, also has the value of utilizing, can also be further by secondary, three times the degree of depth is purified, if dense water is used as direct discharging of waste water, not only can increase the water purification cost, and also be a kind of waste concerning water resources, this has restricted further popularizing of reverse osmosis membrane water-purifying machine undoubtedly.
The utility model content
For addressing the above problem, the purpose of this utility model provides a kind of non-wastewater discharge reverse osmosis water purifier, making dense water can access degree of depth purification filters, improve former water use efficiency, the conserve water resource utilizes the domestic water delivery pipe periodically to emit the more and more higher dense water of concentration, by increasing recycle pump, make water on one side,, prolong its work-ing life Yi Bian utilize a large amount of circulating water flushing reverse osmosis membranes.
For achieving the above object, the utility model is by the following technical solutions:
A kind of non-wastewater discharge reverse osmosis water purifier, comprise topping-up pump, recycle pump and Pyatyi filter cylinder, cotton filter core of polypropylene or active carbon filter core are housed in first three grade filter cylinder, the reverse osmosis membrane filter core is housed in the fourth stage filter cylinder, in the level V filter cylinder active carbon filter core is housed, it is characterized in that:
