The invention relates to a dry-process electric bag combined dust removal
system for eliminating
smoke plume by using a converter primary
flue gas ultralow emission. The
rotary furnace is connected with a
vaporization cooling
flue, the evaporative cooling
flue is connected with an
evaporative cooler, the
evaporative cooler is sequentially connected with an electrostatic dust remover, a multi-pipeanti-explosion
flame arrester, a pulse cloth bag dust remover, a
smoke eliminating device, a fan, a switching
station and a
chimney through a
flue gas pipeline, wherein the switching
station is further connected with a
coal cabinet, the electrostatic
dust collector, the multi-tube anti-explosion
flame arrester and the pulse cloth bag dust remover are connected with a pneumatic ash conveying
system, the pneumatic ash conveying
system is connected with a compressed
nitrogen gas source, the compressed
nitrogen gas source is further connected with the
evaporation cooler, the multi-tube anti-explosion
flame arrester and the pulse cloth bag
dust collector, the dry-process electric bag combined dust removal system for eliminating the
smoke plume by the primary
flue gas of the converter is anti-explosion and anti-condensation, the
flue gas emission is ensured to reach the standard, the
water vapor in the flue gas is eliminated, the
corrosion to the pipeline is reduced, and the
smoke plume is eliminated.
