摘要:
Disclosed is a method for processing an exhaust gas containing an alkaline substance, the exhaust gas being emitted when activating a carbon material with an alkaline substance (1). The method includes the steps of preparing a humidified gas (2), which exhibits a dew point of 25 °C or more, by mixing an inert gas with water vapor (3), generating a hydroxide of metallic alkali by mixing the humidified gas with the exhaust gas; and trapping the generated hydroxide out of the mixture gas of the humidified gas and the exhaust gas (4).
摘要:
A waste gas treatment system having a burner part and a combustion chamber provided at the downstream side of the burner part, wherein combustion flames are formed from the burner part toward the combustion chamber, and a waste gas is introduced into the combustion flames, thereby oxidatively decomposing the waste gas. The combustion chamber is formed from an inner wall made of a fiber-reinforced ceramic material. Therefore, the wear of the inner wall due to heat and corrosion is minimized, and thermal stress cracking is also reduced. Consequently, the lifetime of the system increases, and the cost of equipment and the availability factor can be improved. In addition, because the inner wall exhibits no catalytic effect, the formation of thermal NOx is suppressed, and it is possible to achieve environmental preservation and to simplify the treatment equipment.

摘要:
An exhaust gas treating device which has a burner section, and a combustion chamber disposed downstream of the burner section, which produces a combustion flame that is directed from the burner section toward the combustion chamber, and which introduces exhaust gases into the combustion flame to oxidize the exhaust gases for decomposition, wherein, since the combustion chamber has its inner wall formed of fiber-reinforced ceramic material, the heat resistance and corrosion resistance of the inner wall are improved and at the same time since the inner wall exerts no catalytic effect, generation of thermal NOx is suppressed. Further, since the burner section has a cooling means installed in a supporting gas inlet section, ignition and explosion of the supporting gas are prevented. Further, deposition of dust is prevented by the formation of a swirling flame produced by the burner section or it is prevented by a deposition preventing means or a scraping means.
