Title:
EXHAUST GAS PROCESSING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2011/152551
Kind Code:
A1
Abstract:
The disclosed system is equipped with: a desulfurizing device (15) that eliminates sulfur oxides in exhaust gas (12) from a boiler (11); a cooling tower (16) that eliminates residual sulfur oxides in the exhaust gas, and that reduces the gas temperature; an absorption tower that brings CO2 in the aforementioned exhaust gas into contact with a CO2 absorption liquid, eliminating the CO2; a CO2 recovery device (17) that releases CO2 from the CO2 absorption liquid and recovers the CO2, and that comprises a regeneration tower that regenerates the CO2 absorption liquid; a heat exchanger (32) that is provided to the entrance pathway side of the aforementioned desulfurizing device, and that decreases the temperature of the exhaust gas; and a calcium carbonate spray device (31) that sprays calcium carbonate between the heat exchanger (32) and an electric dust collector (14). Mist-generating substances in the exhaust gas are converted from a gas state to a mist state, and by means of the calcium carbonate, the mist generating substances in the mist state are collected and eliminated.
