Title:
TREATING APPARATUS FOR EXHAUST GAS CONTAINING SULFURIC ACID MIST AND TREATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2008/038348
Kind Code:
A1
Abstract:
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).
