Ship power generation system

Abstract

The invention provides a ship power generation system. The ship power generation system comprises a waste heat power generation system, the waste heat power generation system comprises an interlayer sleeve, the interlayer sleeve comprises an inner sleeve communicated with a power unit exhaust manifold and an outer sleeve which sleeves the inner sleeve, a closed water storage cavity is formed between the inner sleeve and the outer sleeve, and a water feeding pipe is arranged at the lower portion of the water storage cavity; a steam pipe is arranged at the upper portion of the water storage cavity and connected with a steam generator; and electric valves are arranged on the water feeding pipe and the steam pipe, a temperature sensor and a pressure sensor are arranged on the steam pipe, and the electric valves, the temperature sensor and the pressure sensor are electrically connected with s control panel. According to the ship power generation system, high-temperature exhaust discharged by a power unit is used for heating cold water to obtain high-temperature steam so as to drive the steam generator to do work, the heat value of the high-temperature exhaust is recycled to obtain electric quantity, and meanwhile the discharging temperature of the high-temperature exhaust is reduced, and the purpose of restraining infrared radiation is achieved; and meanwhile, consumption of non-renewable energy sources in an existing power generation device is reduced, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of ship power generation, and in particular relates to a ship power generation system. Background technique [0002] Only a small part of the heat generated by the fuel combustion of ship power units does work, and a small part of the remaining heat is taken away by the cooling system, and the other part is released into the atmosphere through exhaust. The exhaust loss accounts for about 40% of the total energy. If the calorific value in a part of the exhaust gas is not utilized, it will not only increase the heat radiation value of the ship, increase the probability of the ship being discovered, but also cause a great waste of resources. [0003] When the ship is sailing at sea, on the one hand, the electric energy required by the crew for normal work and life is mainly obtained by burning non-renewable energy to drive the generator to do work (such as natural gas / diesel power generation or boiler steam pow...
