Specific embodiment
Embodiment of the present invention is illustrated now in conjunction with attached drawing, the present invention is not limited to the following examples.
As shown in Figure 1, a kind of anti-marine internal combustion engine exhaust apparatus poured water, including exhaust pipe 1 and chimney, chimney include cylinder
Shape chimney body 2 and water blocking coaming plate, water blocking coaming plate are arranged along the top outer rim of the top plate 3 of chimney body, and exhaust pipe top passes through
The roof center is connected with top plate seal, and the top exit of exhaust pipe is beveling mouth structure.
As shown in Fig. 2, exhaust pipe is made of the upper bend pipe 4 and lower straighttube 5 of inside and outside socket, close to the position of upper bend pipe on top plate
Connection pedestal 6 is installed, position corresponding with connection pedestal is equipped with upper connecting flange 7, upper connecting flange and company on upper bend pipe
It connects pedestal to be connected by bolt, is equipped with the first sealing ring 10 between upper connecting flange and connection pedestal；On lower straighttube it is close with it is upper
The position of bend pipe socket is equipped with lower connecting flange 8, is equipped with the second sealing ring 11 in lower connecting flange top and the gap of upper bend pipe,
Second sealing ring is equipped with pressing plate 9, and pressing plate is connected with lower connecting flange by bolt.Flexible suspension is equipped between top plate and pressing plate
15, the both ends of flexible suspension are connected with top board undersurface and pressing plate top surface respectively, and the first sealing ring and the second sealing ring are aramid fiber
Fiber fireproof material sealing ring.
As in Figure 3-5, water blocking coaming plate includes front apron 12, rear baffle 13 and side baffle 14, and front apron and side baffle are perpendicular
Straight setting, front apron are lower than the minimum point of exhaust pipe top exit, and to prevent a large amount of ponding from entering exhaust pipe, rear baffle leans outward
Tiltedly setting, rear baffle setting corresponding with exhaust pipe top exit and the highest point for being higher than exhaust pipe top exit, to prevent from coming
It is attacked from the water cannon direct projection in stern direction, water is injected into internal combustion engine from exhaust pipe, exhaust pipe top exit center and rear baffle
Minimum perpendicular distance is not less than the internal diameter of exhaust pipe, and to prevent exhaust back pressure and exhaust noise excessive, the angle of inclination beta of rear baffle is small
In the chamfer angles alpha of exhaust pipe top exit, the exhaust gas conducive to internal combustion engine discharge is smoothly discharged above chimney, and α is preceding less than 45 °
Drainage grill 16 and drainage hole 17 are equipped on baffle, rear baffle and side baffle, top plate is equipped with drainpipe, and drainpipe is connected to cabin
Bottom prevents top plate top ponding from entering inside internal-combustion engine vent-pipe, and chimney body side wall is equipped with ventilative grid 18, guarantees chimney
It is normal ventilative.
Water cannon direction of attack is six dimensions of up, down, left, right, before and after, and the water projected is the high pressure water for being concentrated into stock,
The invention is avoided well by way of increasing chimney water blocking coaming plate and changing internal-combustion engine vent-pipe outlet shapes from ship
The water cannon direct projection in tail direction is parabolically attacked, and is thus prevented the high pressure water for being concentrated into stock to enter internal combustion engine from exhaust pipe and is led
Cause machine impaired；The water-jet of water cannon can be stopped to enter exhaust pipe although increasing chimney water blocking coaming plate, chimney can be brought again simultaneously
The drawbacks of any standing water on top, therefore, chimney water blocking coaming plate, are equipped with drainage grill and drainage hole, and chimney top plate is equipped with draining
Pipe, can effectively prevent on chimney covering exhaust pipe along ponding and enter internal combustion engine causes machine impaired；Increase chimney water blocking coaming plate
Another drawback is: the ponding of chimney top can be made to enter in chimney and cabin by the gap of exhaust pipe, and the present invention will be interior
Combustion engine exhaust pipe is divided into upper and lower two sections in chimney outlet, both can guarantee that exhaust pipe and chimney are tightly connected, has prevented water from exhaust
The gap of pipe enters cabin, ensures that exhaust pipe has certain free extension amount under thermal stress effect, prevents exhaust pipe
Thermal stress is passed into Ship Structure.
