Title:
EXHAUST GAS PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026114
Kind Code:
A1
Abstract:
This exhaust gas processing device is provided with: a mercury oxidation catalyst device to which mercury-containing exhaust gas from the combustion of a carbon-containing solid fuel is introduced, and that oxidizes the mercury in the exhaust gas to divalent mercury; an injection device that injects sulfur trioxide into the flue through which the exhaust gas released from the mercury oxidation catalyst device flows; and a dust collection device that collects dust in the exhaust gas that has passed through the injection device. The injected sulfur trioxide is adsorbed by the dust, and inhibits mercury from being adsorbed by the dust collected by the dust collection device.
