Abstract

The invention relates to a bactericidal backwashing water purifier with a flow control function. A backwashing wastewater pipe is arranged on the water inlet end of a RO reverse osmosis membrane processing unit, the water outlet pipe of the RO reverse osmosis membrane processing unit is connected to a pressure tank, a non-return valve is arranged on the pipeline that connects the water outlet pipe of the RO reverse osmosis membrane processing unit and a water storage barrel; the water outlet pipe of the RO reverse osmosis membrane processing unit is connected to a water flow sensor (14), the sensor is connected to a PLC (15), the PLC (15) starts or closes a water pump according to the signals from the sensor, and the water storage barrel and water pipes all comprise bactericidal materials. The water purifier has the advantages that the service life of RO reverse osmosis membrane is prolonged, the energy consumption is reduced, and the wastewater yield is reduced.

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...
