Abstract

The invention discloses a carbon residue recovering and utilizing device in the aluminum electrolysis industry. The device comprises a floatation tank and a processing tank arranged in the floatationtank. The processing tank is opened upwards. The upper side of the processing tank is provided with a support. A delivery mechanism is fixedly arranged on the support. The delivery mechanism deliversa carbon residue solution to the processing tank and comprises a temperature detection unit and a valve unit. A liquid level detection mechanism is arranged in the processing tank. When the carbon residue solution in the floatation tank reaches a predetermined amount, the feeding is stopped automatically; at the same time, during the feeding process, the temperature of the carbon residue solutionis measured, after the feeding is stopped, a capture agent is added automatically based on the temperature of the carbon residue solution; compared with artificial adding, the efficiency is largely improved, moreover, the amount of the capture agent is more accurate, the waste of the capture agent is avoided, and the cost is reduced for the enterprises.

Description

technical field [0001] The invention relates to a carbon slag recovery and utilization device in the aluminum electrolysis industry, and mainly relates to the technical field of carbon slag recovery. Background technique [0002] In the aluminum electrolysis industry, the carbon materials in the electrolytic cell include carbon anodes, carbon protective rings, and cathode carbon blocks. During the electrolysis operation, due to the quality of the carbon product itself, or being washed by the electrolyte and gas, and other mechanical factors, the carbon Particles fall off. Because the density is lower than that of the electrolyte, the carbon particles are free in the electrolyte, which increases the resistance of the aluminum electrolyte, reduces the conductivity, and increases the energy consumption of electrolysis. Therefore, it is necessary to regularly salvage carbon slag to clean the electrolyte of the electrolytic cell and improve the process indicators; [0003] At the...
