The invention provides a
system for
coupling charging bucket pressure-equalizing
coal gas
recovery and blast-furnace gas dry dust removal. The
system comprises a furnace top pressure-equalizing
coal gas
recovery device and a blast-furnace gas dry dust removal device, wherein an inlet of the upper end of the furnace top pressure-equalizing
coal gas
recovery device is connected with a charging bucket; an outlet of the upper end of the furnace top pressure-equalizing
coal gas recovery device is connected with a
coal gas pipe network; a dust
discharge hole is formed in the lower end of the furnacetop pressure-equalizing
coal gas recovery device; a dust conveying port is formed in a side wall of the furnace top pressure-equalizing coal gas recovery device; an inlet of the blast-furnace gas drydust removal device is connected with a
blast furnace; an outlet of the blast-furnace gas dry dust removal device is connected with the coal gas
pipe network through TRT; a dust
discharge hole is formed in the lower end of the blast-furnace gas dry dust removal device; the dust discharging hole of the blast-furnace gas dry dust removal device is connected with the dust conveying port through a dust conveying
pipe; the outlet of the blast-furnace gas dry dust removal device is connected with the dust conveying pipe through a purified gas pipe for conveying dust. The invention also provides a method for
coupling charging bucket pressure-equalizing coal gas recovery and blast-furnace gas dry dust removal, which adopts the
system for
coupling charging bucket pressure-equalizing coal gas recovery and blast-furnace gas dry dust removal. According to the system and the method for coupling charging bucket pressure-equalizing coal gas recovery and blast-furnace gas dry dust removal provided bythe invention, the furnace top pressure-equalizing coal gas recovery device and the blast-furnace gas dry dust removal device are coupled into a whole, so that resources are saved, and the cost is low.
