Abstract

The invention relates to a flow-controlled backwashing and sterilizing 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, the PLC15 controls the startup or shutdown of a water pump according to signals of the sensor, and the water storage bucket, water pipes and the like are all made from sterilizing materials. The flow-controlled backwashing and sterilizing 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 backwash osmotic water purifier. Background technique [0002] At present, the main problem of osmotic water purifier products is that the cost of RO reverse osmosis membrane is high and it is easily damaged. The RO reverse osmosis membrane of the existing reverse osmosis water purifier has a short service life, and the time for replacing the RO reverse osmosis membrane is not well controlled, resulting in either not being replaced in time, or the RO reverse osmosis membrane is replaced before the end of its service life. cause waste. [0003] Therefore, if the RO reverse osmosis membrane can be washed in time to avoid the accumulation of particles on its surface, the service life of the RO reverse osmosis membrane can be increased and the user's use cost can be reduced. Although there are currently related designs for the backwashing of RO reverse osmosis membranes, the existing designs a...
