Abstract

The invention discloses a compressed air system for a ship. The compressed air system for the ship comprises a main air compressor, a working air compressor, a working air cylinder and main air cylinders. The main air compressor is connected with the main air cylinders, the working air compressor is connected to the working air cylinder through a first air supply pipeline, a compressed air dryer is connected to the air output end of the working air cylinder, a first air output pipe and a second air output pipe are connected to the air output end of the compressed air dryer, the first air output pipe serves as a supply pipe for compressed air for injection of an SCR system of a main engine, the second air output pipe is divided into three branch output pipes, and the three branch output pipes serve as a supply pipe for compressed air used for blowing of the SCR system of the main engine, a supply pipe of compressed air used for ventilation of the SCR system of the main engine and a supply pipe connected to a control air cylinder respectively; and the main air compressor is connected to the air input end of the working air cylinder through the second air supply pipeline. The compressed air system for the ship reduces cost, and is high in emergency capability and high in reliability.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a marine compressed air system. Background technique [0002] The marine compressed air system is mainly used to provide compressed air for the marine diesel engine main engine, generator, SCR system (diesel engine exhaust catalytic treatment system) and pneumatic control system. [0003] Marine compressed air systems in the prior art such as image 3 As shown, the marine compressed air system includes two independent subsystems, one subsystem is the SCR compressed air subsystem, which is used to provide the SCR system of the main engine with the required compressed air for injection, compressed air for blowing, ventilation Compressed air is used; another subsystem is the pneumatic control compressed air subsystem, which provides compressed air for control of the air motor and other pneumatic control components used for generator startup. These two sub-systems use indep...
