Exhaust system of a ship and wet exhaust device thereof

Abstract

The invention discloses a ship exhaust system and a wet exhaust apparatus thereof. The wet exhaust apparatus is connected in the ship exhaust system, and comprises a main body pipe, a gas inlet pipe,a water inlet pipe and a gas exhaust pipe, wherein the gas inlet pipe and the water inlet pipe are disposed at a first end surface of the main body pipe, the gas exhaust pipe is disposed at a second end surface of the main body pipe; the gas inlet pipe is connected to an outlet end of a first smoke exhaust pipe, the water inlet pipe is connected to a first outlet end of a seawater discharge pipe;the gas exhaust pipe is connected to an inlet end of a second smoke exhaust pipe, a first elbow is connected to the gas exhaust pipe; and the first elbow is disposed in the main body pipe, and the endopening of the first elbow is disposed downward, wherein the distance between the bottommost position at the end opening of the first elbow and a centerline of the gas exhaust pipe is between a radius of the gas exhaust pipe and a half of the exhaust backpressure of a diesel generator. According to the ship exhaust system and the wet exhaust apparatus thereof, the discharge of black smoke is effectively reduced, the emission of atmospheric sulfides is reduced, and waves are effectively prevented from flowing backwards to influence the diesel generator.

Description

technical field [0001] The invention relates to the technical field of exhaust systems of ships, in particular to an exhaust system of ships and a wet exhaust device thereof. Background technique [0002] Usually, the outlet of the exhaust pipe of the diesel generator of the ship is arranged above the compass deck of the ship and exhausted to the atmosphere, but some ships cannot arrange the outlet of the exhaust pipe above the compass deck of the ship due to space and functional reasons. It is necessary to arrange the outlet of the exhaust pipe at the stern of the ship or near the heavy-load waterline on both sides, such as figure 1 As shown, the exhaust system is used to exhaust the flue gas of the diesel generator 100 and cool the seawater, including the exhaust pipe 200, the muffler 300, the seawater side pipe 400 and the shut-off valve 500, wherein the inlet end of the exhaust pipe 200 is connected to On the diesel generator 100, the outlet end is set at the stern or b...

Problems solved by technology

Although this method meets the normal needs of ships, it has the following disadvantages: (1) figure 2 As shown, when the ship encounters strong wind and waves, the waves will enter the smoke exhaust pipe when the ship is heeling, and it is difficult to flow out, and then there is a danger of flowing into the diesel generator 100; (2) the smoke discharged will blow the ship The outer plate is blackened, which is not beautiful and affects the appearance of the ship; moreover, the sulfide in the smoke is harmful to the crew and passengers and pollutes the environment
