GAS PROCESSING DEVICE AND EXHAUST GAS PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gas processing device which processes a high temperature processed gas with a gas which is prone to be thermally decomposed.SOLUTION: A gas processing device of the invention includes: a processed gas passage in which a processed gas flows; and a sprayer. The sprayer includes: a spray nozzle having a first opening from which droplets of a first liquid is jetted with a first gas; and a second opening which is provided at a periphery of the spray nozzle and jets a second gas. At least a part of the sprayer is disposed in the processed gas passage so that the droplets of the first liquid, the first gas, and the second gas are jetted into the processed gas.
