Problems solved by technology

In order to reduce the temperature of the tank shell, the current 300KA tank sometimes has to adopt the method of forced ventilation, blowing the tank shell with compressed air to cool it down, which obviously cannot be used as a solution under normal production conditions

Embodiment Construction

[0014] On the outer periphery of the electrolytic cell shell 1, several cooling fins 2 are welded. The left and right welding positions of the heat sink 2 should avoid the cradle 3 of the electrolytic cell. The upper and lower welding positions of the heat sink 2 should make its upper end close to the lower side of the tank edge plate, and make its lower end away from the cathode of the electrolytic cell. The upper side of the steel rod 4 is more than 50mm. According to the different sizes of the slot capacity, determine the length, width, thickness and quantity of the cooling fins. For 300KA-500KA electrolytic cells, the length of the heat sink is 400-800mm, the width is 150-400mm, the thickness is 5-25mm, and the number of welded heat sinks for each tank is 70-300. The heat sink is welded in a straight direction. The heat sink is made of ordinary carbon steel. The shape of the heat sink can be rectangular or non-rectangular, such as trapezoidal.

Abstract

A method for improving the heat dissipation of the shell of great aluminium electrolyzer features that several heat radiating plates are welded to the external surface of said shell.

Description

Technical field [0001] The invention relates to a large aluminum electrolytic cell, in particular to a method for strengthening the heat dissipation of a shell of a large aluminum electrolytic cell of 300KA or more. Background technique [0002] With the advancement of electrolytic aluminum production technology, the capacity of the electrolytic cell is increasing, that is, the current intensity passing through the electrolytic cell is increasing, and the calorific value of the cell body is increasing accordingly. In order to maintain the electrothermal balance of the electrolytic cell, the thermal load of the cell shell will inevitably be increased. In some domestic 300KA electrolyzers, before special heat dissipation methods are adopted, the temperature of the tank shell at the side of the tank is as high as 450 ° C or above. In this way, the electrolyte on the inner wall of the tank is not easy to form a complete crust, and the erosion of the high-temperature melt will c...
