A system for improving water quality in an EDI water tank

Abstract

The utility model discloses a system of promoting EDI water tank water quality, and this system is mainly constituted by RO pool, filter, EDI device, electric three -way valve, water production resistivity appearance, water tank and PLC control system. Each group component is connected gradually through the pipeline, and the effluent of RO pool enters EDI device and carries out the depth treatment after the pretreatment of filter, and the water production pipeline of EDI device is connected to the water inlet of electric three -way valve, and is equipped with the water production resistivity appearance for continuously monitoring water production resistivity, and the two effluent openings of electric three -way valve are connected with water tank and RO pool respectively, and form water production recycling circulation pass. PLC control system and EDI device, electric three -way valve and water production resistivity appearance realize electric connection, and can be based on the real -time monitoring data of water production resistivity appearance, and the flow direction switching of electric three -way valve is automatically controlled to EDI device operating state. Effectively guarantee the water quality stability of entering water tank, and significantly promote EDI water tank water quality.
