Description

technical field

[0001] The invention relates to a dust removal system, in particular to a dry electric bag combined dust removal system for ultra-low discharge of primary flue gas from a converter to eliminate smoke plume. Background technique

[0002] Converter steelmaking has become the main steelmaking process of iron and steel enterprises. During the blowing process, the converter produces gas containing mainly carbon monoxide, a small amount of carbon dioxide and other trace components, which also contains a large amount of iron oxide, metal iron particles, and other gases. Fine particles of solid dust will seriously pollute the atmosphere and workshop environment. Therefore, it is an urgent problem to be solved to improve the technical level of the converter dust removal system and effectively control and reduce the emission of air pollutants in steelmaking.

[0003] China's iron and steel industry is in a period of structural adjustment, optimization and upgrading, a...
