Description

Power generation device combining ship tail gas kinetic energy and ocean wind energy
Technical Field
The invention belongs to the field of new energy power generation, and particularly relates to a power generation device combining ship tail gas kinetic energy and ocean wind energy.
Background
The ship main engine is power for marine navigation and operation of ships and is a main source of ship fuel consumption. The temperature of the tail gas of the main engine is as high as 350-450 ℃, and the tail gas of the main engine is directly discharged, so that a large amount of heat energy is wasted, and the environmental temperature is increased. Therefore, it is necessary to utilize the waste heat of the main machine. At present, the waste heat utilization of a marine main engine mainly has two modes: firstly, low-quality waste heat is directly used as a heating source of other equipment; and secondly, the waste heat with high power utilization value and high grade is used for doing work to recover power. The two modes are that heat energy in tail gas of the main engine is directly converted and utilized, when the main engine of the ship stops working, heat energy of the main engine cannot be utilized, and when the main engine continuously works, the heat energy is excessive and waste of the heat energy is caused.
The prior art mainly focuses on the recovery of the waste heat of the high-quality tail gas of the marine diesel engine, so most of the technologies aim at the treatment of the tail gas before the tail gas is externally discharged, and the treated low-quality tail gas is usually discharged into the atmosphere, so that the utilization rate of the tail gas is reduced. Generally, the tail gas discharged after waste heat recovery has a temperature of 50-70 ℃ and has great kinetic energy. If the energy of the part can be recycled, the utilization efficiency of the diesel engine fuel can be improved, and the recycled energy can be supplied to other equipment for use.
Wind energy is a clean and pollution-free renewable energy source, is very environment-friendly by utilizing wind power for power generation, and has huge wind energy content, so that the wind energy is increasingly paid attention by various countries in the world. The sea has sufficient wind energy, and the high chimney of the ship also provides conditions for utilizing the wind energy.
