Compact ship broadside exhaust system

Abstract

The invention discloses a compact ship broadside exhaust system. The compact ship broadside exhaust system sequentially comprises a main engine outlet reducer pipe, an omega-shaped exhaust expansion joint, an exhaust bent pipe, a broadside exhaust square silencer, an exhaust bent pipe, an exhaust baffle valve, a broadside connecting pipe, a broadside flow guide cap, a drainer and the like, a heatinsulation layer is arranged in the broadside exhaust square silencer, heat insulation layers are laid outside an exhaust pipe and pipeline accessories, and the exhaust system is fixed to a ship bodystructure through an elastic hanging bracket. The system adopts various measures to ensure that seawater does not enter the main engine when the ship sails, and vibration and heat of the main engine can be effectively prevented from being transferred to the ship body structure.

Description

technical field [0001] The invention relates to a compact boat side exhaust system, which relates to the design of the side exhaust system in a compact space to prevent seawater from entering the main engine, and belongs to the technical field of boat design. Background technique [0002] Small high-speed boats generally adopt a single-layer full-through main deck ship type, and mainly use side or stern exhaust instead of chimney exhaust. In order to meet the total propulsion power requirements, high-speed boats are generally equipped with multiple low-power high-speed main engines to overcome the problem that a single high-power main engine cannot be arranged, and then the layout of the engine room will be very compact and the main engine driving the outer shafting is often very close to the side. The main engine close to the side is limited by the height of the main deck, the width of the ship and the structure of the side hull. The design of the side exhaust system is dif...

AI Technical Summary

Problems solved by technology

The main engine close to the side is limited by the height of the main deck, the width of the ship and the structure of the side hull. The design of the side exhaust system is difficult and the silencer and exhaust pipe accessories are too close to the side. The conventional design generally does not have a muffler directly Exhaust to the side

[0003] In addition, when there are strong winds and waves or large inclination angles, the side exhaust system is prone to seawater backflow, causing the main engine to be blocked or even flooded, resulting in the main engine not working normally and affecting the safety of the boat.
