Reverse osmosis water purifier with pre-heating system

Abstract

The invention provides a reverse osmosis water purifier with a pre-heating system. The reverse osmosis water purifier comprises a water inlet (1), a reverse osmosis filtering core (5), a concentrated water solenoid valve (6), a concentrated water outlet (7) and a pure water outlet (8), wherein the water inlet end of the reverse osmosis filtering core (5) is connected with the water inlet (1); the concentrated water opening of the reverse osmosis filtering core (5) is connected with the concentrated water outlet (7) through the concentrated water solenoid valve (6); and the pure water opening of the reverse osmosis filtering core (5) is connected with the pure water outlet (8). The reverse osmosis water purifier is characterized in that the pre-heating system (2) is connected between the water inlet (1) and the reverse osmosis filtering core (5); the pre-heating system (2) can keep the temperature of water entering into a reverse osmosis membrane in a range of 20-30 DEG C, and ensures the flux of the reverse osmosis membrane, so that the water making efficiency of the reverse osmosis water purifier is kept at a higher level. Meanwhile, the reverse osmosis water purifier provided by the invention has the advantages of simple and reasonable structure and low cost, and is convenient to combine.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a reverse osmosis water purifier with a preheating system, which belongs to the improvement technology of the water purifier. Background technique [0002] None of the reverse osmosis water purifiers currently on the market have a preheating system. The water production efficiency of a reverse osmosis water purifier has a great relationship with the inlet water temperature. In winter or in areas with low water temperature, the low water production efficiency of ordinary reverse osmosis water purifiers will lead to prolonged shutdown periods and relatively high Much concentrated water. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a reverse osmosis water purifier with a preheating system, which can maintain the water production efficiency at a relatively high level; meanwhile, it has...
