Description
Technical field
The present invention relates to reverse osmosiss field, a kind of pressure energy retracting device and side more particularly, to counter-infiltration system
Method.
Background technology
Reverse osmosiss are also known as reverse osmosis, are to make with certain pressure the solvent in solution pass through reverse osmosis membrane separation out, enter
And make solution reach the purpose of extraction, purification and concentration.In various membrane separation techniques, reverse osmosis technology achieves order in recent years
What people attracted attention develops rapidly, and is widely used to brackish water desalination, chemical industry, pharmacy, medical treatment, food, beverage, drinks, environmental protection etc.
The every field of national economy.
Reverse osmosis process mesohigh concentrated solution highly pressurised liquid energy entrained when discharging is very huge, accounts for feeding stock solution
The 60% of pressure energy, if this portion of energy is recovered and converted to into liquid energy, reverse osmosis process power consumption can
55%～60% or so are reduced, the energy consumption of reverse osmosis process, and then reduces cost will be so greatly reduced, and this purpose reality
Now depend on and utilize Energy Recovery Technology.
Since the seventies, as reverse osmosis technology is applied to sea water/brackish water desalination, various forms of energy regenerating dresses
