A METHOD FOR DESIGNING A PRE-BAKE ELECTROLYSIS CELL SYSTEM AND AN ARRANGEMENT FOR USE IN THIS SYSTEM

摘要

The present invention concerns a method and an arrangement for use in an electrolysis cell system, comprising a hall with electrolysis cells (C) that use anodes of the pre-bake type for the production of aluminium. The electrolysis cells are arranged in two parallel rows at a distance from each other forming an area for transport of materials to and from the cells between them. A centrally arranged structure is located between said rows of cells. The hall further comprises temporary storage of consumed anodes and other material that are removed from the cells, in closable storage arrangements. Hot gases are extractable from the storage arrangements that are arranged in a formation along said structure so that the operations performed on the cells are free from obstruction by the storage arrangements. The storage arrangements have means for connection to extraction connections located close to or at said structure. The storage arrangements are specially designed with means to reduce emissions of gas to the surroundings and to enhance the efficiency of the cooling process. They are also designed to be transported by a vehicle.
