EXHAUST GAS TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an exhaust gas treatment method constituted so as to prevent the blocking of a flow channel caused by the formation of a solid difficult to be treated while suppressing corrosion caused by the acidic gas in an exhaust gas.

SOLUTION: An alkaline aqueous solution 102 of which the pH value is adjusted to 10.0-13.0 is stored in the container 101 of a pretreatment apparatus 100 and the exhaust gas 1 containing the acidic gas sent into the container 101 is brought into contact the alkaline aqueous solution 102. Thereafter, the exhaust gas 1 treated in the pretreatment apparatus 100 is sent into a dust collector 200 to remove fine particles from the exhaust gas 1. Further, the exhaust gas 1 is sent into a neutralization device 300 and brought into contact with the alkaline aqueous solution 302 to be neutralized.
