Replacement tower for recovering copper from electroplating copper cleaning water

The utility model provides a replacement tower for recovering copper from electrocoppering cleaning water, which relates to the technical field of chemical engineering devices, and comprises a tower body, a support frame arranged on the top surface of the tower body, an overflow cavity arranged in the tower body and a filter structure arranged in the tower body, the filter structure comprises a tower tray, and a fitting plate arranged on the top surface of the tower tray. First filtering holes and second filtering holes are formed in the tower tray and the attaching plate in a circumferential array mode respectively, a replacement column is embedded in a connector in the circle center of the tower tray, the filtering structure is changed, liquid obtained after replacement reaction can be filtered for multiple times, the liquid obtained after replacement is effectively filtered, and the filtering efficiency is improved. Copper-containing particles are prevented from being discharged along with ferrous sulfate
