TREATING APPARATUS FOR EXHAUST GAS CONTAINING SULFURIC ACID MIST AND TREATING METHOD THEREFOR

摘要

A treating apparatus, and treating method, for exhaust gas containing sulfuric acid mist that excel in the elimination performance even for submicron-order sulfuric acid mist. There is provided an apparatus comprising saturating means (26) for saturating through feeding of water in the form of steam, etc. into exhaust gas (19) containing sulfuric acid mist; venturi duct (28) for mist generation through adiabatic expansion of the exhaust gas (19) having passed through the saturating means (26); ion generating means (30) for generating of ions in the vicinity of throat portion (48) of the venturi duct (28); and wet electric dust collector (32)disposed downstream of the venturi duct (28). Control unit (46) controls the amount of water required for saturating of the exhaust gas (19).
