Abstract

The invention relates to a flow-controlled backwashing and osmosizing water purifier. A backwashing wastewater pipe is arranged at a water inlet end of an RO (Reverse Osmosis) membrane treatment unit, a water outlet pipe of the RO membrane treatment unit is further connected with a pressure tank, a pipe line, connected with a water storage bucket, of the water outlet pipe of the RO membrane treatment unit is further connected with a one-way valve, the water outlet pipe of the RO membrane treatment unit is connected with a water flow sensor 14, the sensor is connected with a PLC15, and the PLC15 controls the startup or shutdown of a water pump according to signals of the sensor. The flow-controlled backwashing and osmosizing water purifier has the beneficial effects that the service life of an RO membrane is prolonged, and the energy consumption and wastewater yield are lowered.

Description

Technical field [0001] The invention relates to a water purifier, in particular to a reverse flushing permeation water purifier. Background technique [0002] The main problem with current permeable water purifier products is that RO reverse osmosis membranes are expensive and easily damaged. The RO reverse osmosis membrane of the existing reverse osmosis water purifier has a short use time, and the time to replace the RO reverse osmosis membrane is not well controlled, which leads to or cannot be replaced in time, or the RO reverse osmosis membrane is replaced before its service life. Cause waste. [0003] Therefore, if the RO reverse osmosis membrane can be flushed in time to avoid the accumulation of particles on its surface, the use time of the RO reverse osmosis membrane can be increased and the user's use cost can be reduced. Although there are related designs for the reverse flushing of RO reverse osmosis membranes, the existing designs are too complicated and cumbersome, ...
