Abstract

The invention relates to a device for merged exhaust by exhaust pipes of a marine diesel engine. A valve body is provided with an exhaust port upward and is provided with at least two flue gas inletsdownward, wherein an adjusting plate is arranged in each flue gas inlet, the axis part of each adjusting plate is connected to an electric executor, and the electric executor can drive the adjusting plate to rotate, so that the flue gas inlet is opened or closed; a first temperature sensing element is arranged on the side, close to the exhaust port, of the adjusting plate, and a second temperaturesensing element is arranged at the part, close to an exhaust pipe of the diesel engine, of the adjusting plate; a controller is connected to the first and second temperature sensing elements and is collected to the electric executor simultaneously, and when the temperature of the second temperature sensing element is higher than that of the first temperature sensing element, the electric executoropens the adjusting plate, and otherwise, closes the adjusting plate. According to the device provided by the invention, the merged exhaust pipes can be isolated effectively according to different conditions, so that the arrangement space of the exhaust pipes on a ship is saved; and all waste heat in exhaust gas of the diesel engine is recovered conveniently, so that the energy sources are savedand the efficiency is improved.

Description

technical field [0001] The invention relates to a marine diesel engine exhaust pipe device, in particular to a device for merging exhaust pipes of marine diesel engine exhaust pipes. Background technique [0002] The layout of the ship's engine room shed and chimney is an important part of the ship's engine room layout. Many ships are affected by the ship's weight, size, wind area, and cost. pressure. The cabin shed and chimney are mainly used to arrange the exhaust pipe of the diesel engine. When there are many diesel engines on the ship, it is urgent to arrange the exhaust pipe more reasonably, which is convenient for overhaul and maintenance, and reduces the construction cost. [0003] Usually, there are more than two diesel generator sets for marine power generation. According to specific application scenarios, one is generally used and one is used for backup, or dual-purpose and one is used for backup. The combination of exhaust pipes of diesel engines is to take int...
