Operation principle of the present utility model is:
The process of reverse osmosis water purifying plant controlling the water circulation, it is simply that the process that former water is concentrated.Some low dissolvings in former water
Degree solute (such as CaCO3, CaSO4, SiO2 etc.) can reach hypersaturated state, easy crystallization, is deposited on filter element 6 surface (knot
Dirt).Therefore, during reverse osmosis controlling the water circulation, need to discharge a certain proportion of condensed water, to carry discharge low solubility solute,
Prevent filter element 6 fouling.Net water recoveries is the highest, and the condensed water ratio of discharge is the lowest, and the risk of fouling is the biggest.Through filtration core 6
The water that purifies after reverse osmosis has filtered the most low solubility salt in water, and degree of unsaturation is high, dissolving power is strong, can dissolve
The slight fouling on filter element 6 surface.
This practicality uses water bag 2 to store the reverse osmosis-purified water after purifying, and in order to realize " high pressure just rinses " and " minute-pressure
Backwash " douching technique of filter element 6, discharge the dense water of trace during controlling the water circulation, controlling the water circulation is clean with the reverse osmosis of water bag internal memory after terminating

Back purge system 3 has had the biggest breakthrough technically, rational in infrastructure, and makes water bag internal containing certain
Pressure, freely changes on intake-outlet, it is not necessary to increase auxiliary equipment.Go out through the water treatment facilities equipped with back purge system 3
The purification water come is entered back purge system 3 by water inlet, and certain purification water collected by water bag, presets when internal pressure reaches equipment
After pressure, the water treatment facilities equipped with back purge system 3 quit work.Now in filter element 6, the former water mobility of water inlet flow channel is non-
Constant, the water on filter element 6 (RO reverse osmosis membrane or ultrafilter membrane) top layer, easily excessively concentrate and reach hypersaturated state, at filter element 6 table
Layer crystallization, produces fouling；And back purge system 3 is after equipment quits work, water bag is internal automatically forms a pressure with outside
Difference, promote the internal water of back purge system 3 by the relatively small clean water area of inside and outside differential pressure automatic stream pressure, by soaking
Dissolve directly to rinse to remain in during controlling the water circulation and inside filter element 6, attach pollutant and crystalline solid, rinse out blocking or adhere to
Micropollutants, and the unnecessary water that purifies can station in the shell of filter element 6, reduces fouling risk, is ensureing the same of water quality
