Abstract
The invention discloses a reverse osmosis (RO) treatment system for water for a boiler. The reverse osmosis treatment system comprises a security filter, a high-pressure pump and a reverse osmosis system which are connected with one another in sequence along a water flow direction, wherein a scale inhibitor adding system and a NaHSO adding system are arranged at a water inlet end of the security filter, and a PLC (programmable logic controller) controlled electronic control valve is arranged at a water inlet end of the high-pressure pump. According to the reverse osmosis treatment system for water for the boiler, disclosed by the invention, the aperture size of a reverse osmosis membrane of the reverse osmosis system is only 3*10<-10>m, and therefore the reverse osmosis membrane is ion-class separation equipment, wherein the separation object is organic substances with a very small ion range and small molecular weights in a solution, and 99.9% of the organic substances and bacteria and 98% of salts can be removed from water by virtue of reverse osmosis to ensure that the water quality is greatly improved; and meanwhile, the electronic control valve arranged on the system is switched on under the control of a PLC, so that the pressure of the reverse osmosis system can be conveniently controlled, and damages to RO membrane elements due to sudden starting pressurization of the high-pressure pump can be avoided.
