Description

A kind of small reverse osmosis system

Technical field

The utility model belongs to dense water recycling technical field, relates in particular to a kind of reverse osmosis system.

Background technology

Reverse osmosis technology is a kind of membrane separation technique that is mainly used in pure water preparation, time of the U.S., Japanology exploitation early, start from 1966 in China, until just be used widely in recent years, the principle of work of reverse osmosis technology is: utilize the selectivity of reverse osmosis membrane to see through function, when the intake pressure in the system during greater than the osmotic pressure of water, water molecules constantly pass reverse osmosis membrane then the multiparity water flow passage flow into pipe core, thereby obtain pure water.The small reverse osmosis system that is used at present dense water recycling mainly comprises raw water box, raw water pump, strainer, softening agent, high-pressure pump, reverse osmosis unit, pure water tank, its working process is: the dense water in the raw water box is at first by the effect of raw water pump flow through strainer and softening agent, and then enter reverse osmosis unit by high-pressure pump, through behind the reverse osmosis membrane in the reverse osmosis unit standard compliant pure water being recycled, remaining dense water is then discarded, because the infiltration standard of each reverse osmosis membrane is 15%-18%, the dense water rate of recovery of reverse osmosis system is the highest can only to be 50%, the rate of recovery is lower like this, thereby make the profit of enterprise also just lower, have a strong impact on the fast development of enterprise.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides the high small reverse osmosis system of a kind of rate of recovery, comprise the raw water box that connects successively, raw water pump, quartz filter, activated charcoal filter, the resin softening agent, cartridge filter, be provided with former water automatic tank gauge on the described raw water box, also comprise the salt case, pipeline A, reverse osmosis unit, pure water tank, pipeline B, pipeline C, described salt case be connected the resin softening agent and connect, described cartridge filter be connected reverse osmosis unit and connect by described pipeline A, be disposed with high-pressure pump and water inlet vacuum breaker on the described pipeline A, described reverse osmosis unit be connected pure water tank and connect by pipeline B, be disposed with variable valve A on the described pipeline C, under meter A and and be connected reverse osmosis unit connection, it is characterized in that: also comprise being disposed with variable valve B, under meter B, the pipeline D of backwater vacuum breaker, the end of described pipeline D and described reverse osmosis unit, pipeline C between the variable valve A connects, the other end and described cartridge filter, pipeline A between the high-pressure pump connects.

Be provided with the Scale inhibitors adding set between described resin softening agent and the described cartridge filter.

The beneficial effects of the utility model are: the pipeline D that is provided with variable valve B, under meter B, backwater vacuum breaker by increase, make the dense water rate of recovery reach 65%, improve 15% than common small reverse osmosis system, improve production efficiency, increased enterprise profit, in addition also accelerated the flow velocity of dense water in reverse osmosis membrane, thereby the poor polarization phenomena of purulence on reverse osmosis membrane surface have been reduced, reduce fouling tendency, prolonged the work-ing life of reverse osmosis membrane, reduced the production cost of enterprise.
