Abstract:
A method of cooling incinerator exhaust gas for a cleaning treatment of high temperature exhaust gas discharged from a waste incinerator, the method comprising introducing the incinerator exhaust gas into a spray cooling chamber having a gas distribution chamber at an upstream side thereof while imparting a revolving flow to the incinerator exhaust gas, mixing the incinerator exhaust gas with a cooling liquid sprayed in the spray cooling chamber to rapidly cool the temperature of the incinerator exhaust gas to a predetermined temperature or less, and removing dust from the incinerator exhaust gas in a dried state, wherein a gas speed of the exhaust gas in the gas distribution chamber is 10 to 50 m/sec, and a revolution speed of the gas is 1 to 30 rad/sec.
