<p><P>PROBLEM TO BE SOLVED: To remove highly efficiently acidic gas in exhaust gas by obtaining porous sodium bicarbonate without using exhaust gas for a carrying medium of sodium bicarbonate. <P>SOLUTION: Sodium bicarbonate is supplied to a sodium bicarbonate carrying pipe 12 via an air sending pipe 15 by a blower 16, and is added to exhaust gas containing acidic gas discharged from an incinerator 2, using carrying air as a carrying medium, heated to 140°C or higher by a carrying air heater 17, and is carried to a dust collector 6 together with the exhaust gas. The sodium bicarbonate layer formed on the filter cloth surface of the dust collector 6 is reacted with the acidic gas passing therethrough to neutralize and collect it, to remove the acidic gas. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
