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
The present invention relates to a kind of cooling unit of diesel engine, particularly relate to a kind of marine diesel engine water-cooling exhaust pipe.
Background technique
Because marine diesel engine is in the process of work, the temperature of its engine smoke discharging mouth is often very high, usually about 400 degree are reached, thus cause engine environment ambient temperature too high, have a strong impact on the working stability of motor and the working life of engine components, particularly when cabin on ship is less, this drawback is more obvious, also can cause certain potential safety hazard simultaneously.
Summary of the invention
For above deficiency, the invention provides a kind of marine diesel engine water-cooling exhaust pipe, effectively reduce the temperature of engine smoke discharging mouth, and structure is simple.
To achieve these goals, the technical solution used in the present invention is: a kind of marine diesel engine water-cooling exhaust pipe, comprises housing and interts the gas exhaust duct that is arranged in housing, and described gas exhaust duct stretches out the outside of housing as one end of smoke exhaust port; Chamber between described gas exhaust duct and housing forms cooling water channel, and described housing is provided with the water intake and water outlet that are communicated with cooling water channel.
Preferably, described housing is provided with at least one motor and enters mouth, and accordingly, described gas exhaust duct is provided with at least one smoke inlet flue be connected with gas exhaust duct for described motor being entered mouth vertically.
Preferably, in the cooling water channel of described smoke inlet flue between described gas exhaust duct and housing.
Preferably, described housing is provided with at least one motor and enters mouth, and accordingly, described gas exhaust duct is provided with at least one smoke inlet flue vertically.
Preferably, described housing, gas exhaust duct and smoke inlet flue are integrated casting.
Beneficial effect of the present invention:
Structure of the present invention is simple, novel, effectively utilize the circulating water of motor, the design of Water-cooling circulating pipeline is added between the housing and gas exhaust duct of motor, gas exhaust duct is made to be positioned at cooling water channel, enter the cooling water channel in this outlet pipe when circulating water of engine after, timely gas exhaust duct can be cooled, thus effectively reduce the temperature of engine smoke discharging mouth.The temperature of usual engine smoke discharging mouth is at about 400 degree, after this water-cooling exhaust pipe, temperature can drop to about 80 degree, improves the environment of engine environment greatly, time particularly cabin is less aboard ship, obvious improvement result is played to the temperature of surrounding, for the operation that engine high-efficiency is stable provides abundant guarantee, effectively extend the working life of engine components, simultaneously, effectively stop potential safety hazard, optimize working environment.

Embodiment
Be further elaborated the present invention below in conjunction with accompanying drawing, referring to figs. 1 through Fig. 4, marine diesel engine water-cooling exhaust pipe of the present invention, it comprises housing 1, gas exhaust duct 2 and cooling water channel 3, and housing 1, gas exhaust duct 2 and smoke inlet flue 21 are integrated casting.
The inside of housing 1 is the chamber of hollow, and gas exhaust duct 2 is interspersed to be arranged in housing 1.
Gas exhaust duct 2 is arranged along the length direction of housing 1, and the left end of gas exhaust duct 2 is closed and is positioned at the chamber of housing 1, and the right-hand member of gas exhaust duct 2 is that opening arranges and stretches out the outside of housing 1, thus forms smoke exhaust port 23, for getting rid of flue gas; Smoke inlet flue 21 is arranged on gas exhaust duct 2, and arrange several along the axis of gas exhaust duct 2, each smoke inlet flue 21 extends on housing 1 along the radial direction of gas exhaust duct 2, smoke inlet flue 21 defines into mouth 22 on housing 1, for entering in gas exhaust duct 2 by the cigarette that motor is discharged, in housing 1, multiple gas exhaust duct 2 also can be set.
Cooling water channel 3 is formed by the chamber between gas exhaust duct 2 and housing 1, and housing 1 is provided with the water intake 31 and water outlet 32 that are communicated with cooling water channel 3.
Working procedure of the present invention is: when after engine operation, the temperature of motor smoke outlet flue 22 rises rapidly, simultaneously, circulating water of engine is by entering the cooling water channel of this water-cooling exhaust pipe at the water intake of housing 1, utilize circulating water of engine that the gas exhaust duct 2 in housing 1 is cooled timely and effectively, and then effectively reducing the temperature of engine smoke discharging mouth 23, the circulating water then absorbing heat is discharged from water outlet 32.
The foregoing is only better embodiment of the present invention, the present invention is not limited to above-mentioned mode of execution, the structural modification that local is small may be there is in implementation process, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, and belonging within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
