The invention relates to an automatic
ion exchange control device, a control method and a
control system, an acid feeding pipeline, a conventional feeding pipeline and a reverse top liquid discharging pipeline are arranged at the top end of an
ion exchange column, a bottom opening is formed in the bottom end of the
ion exchange column, and a diluted
hydrochloric acid pipeline and a diluted
sulfuric acid pipeline are respectively communicated and connected with the acid feeding pipeline; the
purified water pipeline and the extracting solution pipeline are respectively communicated and connected with the conventional feeding pipeline, the dilute caustic soda liquid pipeline, the
desorption solution pipeline, the blow-off pipeline and the high
ammonia nitrogen blow-off pipeline are respectively communicated and connected with the bottom opening, and the reverse jacking solution pipeline is communicated and connected with the reverse jacking solution discharging pipeline. Automatic feeding and metering are achieved through technological
process control, purification and separation after regeneration of the
ion exchange column and automatic column adsorption are achieved through forward and reverse automatic washing, fraction separation and collection of an extracting solution are achieved through analysis of an online analyzer, frequent field operation of operators is not needed, and the
automation degree is high.
