A preliminary drainage pipe 20, which is a feature of the present invention, is connected to the upstream side of the water seal 4, for example, to the space above the water seal part 13. The drain reserve pipe 20 is normally communicated with the outside air and discharges drain water only when the drain pipe 15 is blocked, and is located at a position H higher than the height h of the water seal portion 13 and at the exhaust port 17. It is configured to be lower. This configuration prevents the engine exhaust gas from bypassing through the drain reserve pipe 20, and also prevents drain water from flowing back toward the engine body when the drain pipe 15 is blocked. Note that the base end opening 20a of the drainage reserve pipe 20 is located at the lower part (underwater) of the drain water collection part 12, the lower part (underwater) of the water seal part 13, and the upper part (underwater) of the neutralization processing part 16, as shown by the chain line in FIG. (space), or a combination of these may be used.

When the drain pipe 15 is blocked by the reaction product during the neutralization process, the water level of the drain water in the drain water treatment device 9 rises, and the untreated drain water is finally discharged from the drain reserve pipe 20. That will happen. At this time,
The level of drain water never exceeds the exhaust port 17. Therefore, the operator who detects drain water being discharged from the drain reserve pipe 20 is able to recognize that the drain pipe 15 is blocked and immediately perform inspection and cleaning. When the drainage pipe 15 is unblocked, the water level in the drain water treatment device 9 returns to normal, and drainage from the drainage reserve pipe 20 is stopped.
