Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to a real-time online monitoring device for the pressure drop temperature at a short-circuit port of an electrolytic cell. Background Art

[0002] Aluminum electrolytic cell is the most important link in the aluminum electrolysis production process. During the operation of the electrolytic cell, the material balance and energy balance state in the cell are constantly changing, and many factors also affect the real-time changes in the cell conditions. Among them, with the rapid development of the aluminum electrolysis industry, the electrolytic cell has developed from a self-baking cell to a large pre-baked cell. Due to the principle and process of aluminum electrolysis, each electrolytic cell in the aluminum electrolysis series is connected in series. Once an electrolytic cell has an accident, it will affect the normal operation of the entire series. Short-circuit explosion is one of the biggest accidents in aluminum electrolytic cells. In severe cases, it will force the entire series of electrolytic cells to stop production, resulting in serious losses, and sometimes even casualties. Production safety is the greatest benefit of the enterprise. Short-circuit accidents seriously endanger the normal operation of aluminum electrolysis production, thereby affecting the production efficiency and other important performance indicators of aluminum electrolytic cells.

[0003] After the short-circuit operation of the stop tank is completed and closed, the technical parameters require that the short-circuit voltage drop must be below 25mV and the temperature must be below 80℃ to effectively ensure the safety of the series power supply. During the overhaul and dismantling of the electrolytic cell, the installation and lifting of the upper structure, the furnace planing, the furnace building, the anode car transporting the anode, and the electrolysis production process, the short-circuit busbar of the short-circuit will be touched, which will directly cause the short-circuit technical parameter voltage drop and temperature rise to exceed the safe range of the technical parameters, affecting the safety of the series power supply. At present, the detection method of the short-circuit voltage drop and temperature of the stop tank is that the team leader performs manual measurement every day, which is labor-intensive and time-consuming, and cannot achieve real-time monitoring, which will lead to uncontrollable risks and affect the safe and stable development of the enterprise. At present, there is no set of electrolytic cell short-circuit monitoring and alarm control device to meet this requirement. It can only be simply patrolled by the electrolysis worker at all times to avoid the explosion of the short-circuit. Once it is not discovered in time, it may cause a major safety accident for the current company's electrolysis series. Therefore, it is very necessary to design a real-time online monitoring device for the voltage drop and temperature of the short-circuit of the stop tank of the electrolytic cell.
