Abstract:
     This invention relates to a dry dust separation method for closed silicon-manganese-ferroalloy electrical furnace. Its technological process is that the gas goes through a dust chamber, coder, and bag-filter to remove dust. After cooling once more and dewatering, the purified gas goes to the gas holder. This invention aviods secondary pollution dueto waste water and sludge. furthermore, the installations for the treatment of waste water and sludge can be omitted.
