[0044] figure 1 with 2 The secondary dust removal equipment according to the present invention is schematically shown based on two typical applications of the steelmaking basic material industry.
[0045] figure 1 An electric arc furnace 1 that is commonly used for smelting steel scrap is shown. The electric arc furnace has a furnace top hole 2 which is adjacent in a sealed manner by a flow channel 3 forming part of the primary dust removal equipment. The primary dust removal equipment is not shown in detail and corresponds to the known prior art. During the continuous smelting process and the subsequent molten steel treatment process, the reaction gas is sucked out of the furnace through the flow channel 3. The exhaust hood 4 for collecting the reaction gas from the electric furnace is arranged above the electric arc furnace, under the roof of the furnace chamber (not shown), and is especially collected during the operation of charging waste into the existing liquid molten st...
