EXHAUST GAS TREATMENT DEVICE

摘要

An exhaust gas treatment device, comprising a guide tube (21) connected to an exhaust gas discharge source and a coolant supply temporary storage part (22), wherein the exhaust gas inlet (21a) of the guide tube (21) is opened upward, and the coolant outlet (22a) of the temporary storage part (22) is disposed so as to surround the inlet (21a) of the guide tube (21), whereby the coolant flowing out from the coolant outlet (22a) is allowed to flow down from all around the periphery (21a') of the inlet (21a) of the guide tube (21) along the inner peripheral surfaces (21c', 21d') thereof, and a coolant film covering the inner peripheral surfaces (21c', 21d') of the guide tube (21) is formed by the coolant flowing down along the inner peripheral surfaces (21c', 21d') of the guide tube (21).
