Abstract: There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet.
