Title:
SIDE-LEDGE MELTING PROCESS SIMULATION DEVICE FOR ALUMINUM ELECTROLYSIS CELL, AND METHOD OF USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/103324
Kind Code:
A1
Abstract:
A side-ledge melting process simulation device for an aluminum electrolysis cell, and a method of using same. The simulation device comprises a simulation device body, an air cooling system, and a temperature control system. The simulation device body has an inverted T-shaped structure, and comprises a base (1) and a rectangular cold wall (2) perpendicular to the base (1). A rectangular cooling cavity (4) is provided within the cold wall (2), and a sealing rod (3) is arranged at the top of the cooling cavity (4). The air cooling system is connected to the cooling cavity (4) and is configured to cool the cooling cavity (4). The temperature control system is arranged in the cold wall (2), and in a molten electrolyte (9) at the periphery of the simulation device body, and is used to measure the temperatures of the cold wall (2) and the molten electrolyte (9). In the invention, a simulation device using a side-ledge growth model for a planar cold wall is constructed according to planar side-walled heat dissipation structures of actual aluminum electrolysis cells. The simulation device can realistically simulate heat dissipation states during operation of an electrolytic cell, and electrolyte precipitation and solidification processes on the simulation device are similar to actual side-ledge growth processes, thereby improving simulation experiment performance.
