Magnetic disk stirring pulse, sine wave gear disk pulse and magnetic drum pulse type electrolysis impurity removing tank

Abstract

The invention discloses a magnetic disk stirring pulse, sine wave gear disk pulse and magnetic drum pulse type electrolysis impurity removing tank. An electrolytic manganese chemical combination leachate storage tank communicates with an electrolytic manganese qualification liquid storage tank through an impurity removing electrolytic tank; the impurity removing electrolytic tank is provided with an electrolysis pole plate with a cathode being stainless steel and an anode being lead alloy; a magnetic disk stirring pulse generator and a sine wave gear disk pulse generator are arranged; the impurity removing electrolytic tank is connected to a liquid inlet of a magnetic drum differential motion type circulating pump through a pipeline, and a liquid outlet of the magnetic drum differential motion type circulating pump communicates with the impurity removing electrolytic tank through a pipeline. According to the electrolysis impurity removing tank, the stainless steel serves as the cathode, the lead alloy serves as the anode, and ions of heavy metal such as copper, zinc, nickel, cadmium and cobalt in solutions are removed during cathodic deposition through electrolysis; through the multiple pulse generators installed in the electrolytic tank, bubble adhesion generated on the surface of the pole plate can be removed, ion distribution can be uniform, and efficient electrolytic impurity removal can be guaranteed; the impurity ion concentration can be lowered to be lower than 1 mg / L, the recovery rate of heavy metal can be higher than 95%, and secondary pollution can be avoided.

Description

technical field [0001] The invention relates to a three-pulsation type electrolytic miscellaneous removal tank with a disk stirring pulse, a sine wave tooth disc and a magnetic cylinder. Background technique [0002] The solution produced by the electrolytic manganese compounding process contains a small amount of heavy metal ions such as copper, zinc, cobalt, nickel, and lead. These ions must be removed to obtain qualified products. [0003] At present, the chemical precipitation method is mainly used, that is, sodium dimethylaminodithioformate (SDD) is added to allow heavy metal ions to precipitate with it. Since the precipitate is mixed in the leach residue and cannot be separated, it will enter the environment with the residue and be piled up. During the process, due to the leaching effect of oxidation and acid rain, these heavy metals finally enter the soil and water environment and form secondary pollution, causing serious harm to the ecological environment and human b...
