Problems solved by technology

[0002] During the working process of the marine diesel engine, the temperature of the exhaust port of the engine is often very high, usually reaching about 400 degrees, which causes the ambient temperature of the engine to be too high, which seriously affects the working stability of the engine and the service life of the engine components. Especially when the cabin on the ship is small, this disadvantage is more obvious, and it will also cause certain safety hazards

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is further elaborated, with reference to Figure 1 to Figure 4 , The marine diesel engine water-cooled exhaust pipe of the present invention comprises a housing 1, a smoke exhaust pipe 2 and a cooling water channel 3, and the housing 1, the smoke exhaust pipe 2 and the flue inlet 21 are integrally cast and formed.

[0017] The inside of the casing 1 is a hollow chamber, and the smoke exhaust pipe 2 is inserted in the casing 1 .

[0018] The smoke exhaust pipe 2 is arranged along the length direction of the housing 1, the left end of the smoke exhaust pipe 2 is closed and located in the chamber of the housing 1, the right end of the smoke exhaust pipe 2 is provided with an opening and protrudes from the outside of the housing 1, thereby forming a smoke exhaust pipe. The smoke outlet 23 is used to remove smoke; the smoke inlet 21 is arranged on the smoke exhaust pipe 2, and several are arranged along th...

Abstract

The invention relates to a water-cooling exhaust pipe for a marine diesel engine. The water-cooling exhaust pipe comprises a shell and a smoke exhaust pipeline arranged in the shell in an inserted manner; the smoke exhaust pipeline as one end of a smoke outlet extends out of the shell; a chamber between the smoke exhaust pipeline and the shell forms a cooling water path; the shell is provided with a water inlet and a water outlet which are communicated with the cooling water path. According to the water-cooling exhaust pipe disclosed by the invention, the temperature of the smoke outlet can be reduced to about 80 degrees, so that the environment around the engine is greatly improved; especially, in case of a relatively small cabin, the water-cooling exhaust pipe plays a remarkable effect of improving the ambient temperature.

Description

technical field [0001] The invention relates to a cooling device for a diesel engine, in particular to a water-cooled exhaust pipe for a marine diesel engine. Background technique [0002] During the working process of the marine diesel engine, the temperature of the exhaust port of the engine is often very high, usually reaching about 400 degrees, which causes the ambient temperature of the engine to be too high, which seriously affects the working stability of the engine and the service life of the engine components. Especially when the cabin on board is smaller, this disadvantage is more obvious, and also can cause certain potential safety hazard simultaneously. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a water-cooled exhaust pipe for a marine diesel engine, which can effectively reduce the temperature of the exhaust port of the engine and has a simple structure. [0004] In order to achieve the above object, t...
