Abstract
An electric power generation system of a container ship comprises an exhaust-gas turbo-generator and an axle generator. The exhaust-gas turbo-generator is directly driven by exhaust-gas which is generated by a main engine used for providing moving force for a ship so as to generate electric power. The axle generator transforms spare kinetic energy of the main engine into electric power. By means of combination of power generation of the exhaust-gas turbo-generator and the axle generator, service hours of a diesel generator is reduced effectively, diesel-consumption is lowered, maintenance cost of the diesel generator is also decreased, and operating economic efficiency of the ship is increased.
Description
Technical field
The present invention relates to the ship power technical field, relate in particular to a kind of power generation system of Container ship.
Background technique
In the boats and ships shipping rate was used, fuel cost accounted for major part wherein, and therefore, reasonable energy utilization reduces fuel consumption, for the economic benefit that improves boats and ships, huge meaning is arranged.Again along with the raising that rises steadily He in the world boats and ships shipping energy-saving and emission-reduction are required of oil price, so, the energy consumption that the green ship of newly making is all considered to adopt various technology to reduce operation of ship usually and the Economy of increase boats and ships.And in order to the main frame of power to be provided to Shipping, it not only has the margin of power more than 10%, and because its power is large, the preheating of the waste gas that discharges is also considerable, therefore, how to utilize the power more than needed of main frame and used heat to generate electricity and become the important topic of paying close attention in the industry.
Axle generator is to utilize the subsidiary generator that drives of shafting of main engine, and it utilizes the rich power of main frame to generate electricity the purpose that reaches energy-conservation, therefore is subject to the attention of various countries' shipbuilding circles and shipping world.But only adopt axle generator, the effect that reduces efficiency is little, so it is energy-conservation usually to adopt the mode of axle generator and steam turbine generation machine combination in prior art, but the complex structure of steam turbine generation machine, the initial investment cost is very high, is difficult in a short time cost recovery.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiency that above-mentioned prior art exists, and a kind of energy-saving power generation system of Container ship is proposed, its mode by axle generator and exhaust gas turbo generator combination is generated electricity, and is not only simple in structure, the initial stage input cost is low, and good energy-conserving effect.
For solving the problems of the technologies described above, the present invention proposes a kind of power generation system of Container ship, comprising: the exhaust gas turbo generator that is generated electricity by direct driving of waste gas that produces in order to the main frame that onward impulse is provided to boats and ships.
The power generation system of described Container ship, wherein, this exhaust gas turbo generator comprises: exhaust turbine, the reduction gear box that is connected with exhaust turbine and the alternator that is connected with reduction gear box, described exhaust turbine is collected the exhaust header of described main frame waste gas by pipeline communication, acting produces rotation function to turbine by the waste gas in exhaust header, slow down and pass to alternator through reduction gear box again, by alternator, kinetic energy being converted to electric energy output.
The power generation system of described Container ship, wherein, this power generation system also comprises axle generator, it is arranged on the output shaft of described main frame, is converted to electric energy with the kinetic energy with main frame output.
The power generation system of described Container ship wherein, is equipped with switch valve between described exhaust header and the pipeline that is connected exhaust turbine.
The power generation system of described Container ship, wherein, this power generation system also comprises diesel generator.
compared with prior art, the present invention has following beneficial effect: the present invention is by being connected the exhaust header of exhaust gas turbo generator with main frame waste gas, the waste-gas heat of main frame discharging directly is converted to electric energy, its with prior art in utilize main frame waste gas to produce steam produces electric energy again by steam driven steam turbine generation machine to compare, its structure is simpler, the initial stage input cost is lower, energy-saving effect is better, in addition, the power generation system of Container ship of the present invention also is converted to electric energy by axle generator is set with the kinetic energy more than needed of main frame, operating cost with further reduction boats and ships.The present invention is by the mode of exhaust gas turbo generator and axle generator combination generating, can also effectively reduce the service time of diesel generator, thereby effectively reduce diesel consumption, also reduced the rate of fault of diesel generator, reduce the maintenance cost of diesel generator, improved the Economy of operation of ship.
Description of drawings
Fig. 1 is the structural representation of the exhaust treatment system of the power generation system of Container ship and main frame.
Embodiment
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
As described in Figure 1, Container ship mainly generates electricity by diesel generator, satisfies power demands, but diesel generator need to expend massive diesel-fuel fuel, causes very large burden for the operating cost of boats and ships.
For reducing the vessel motion cost, realize the purpose of energy-saving and emission-reduction, the invention provides a kind of exhaust gas turbo generator 3 that is converted to electric energy by direct driving of waste gas of Container ship main frame generation, this exhaust gas turbo generator comprises: exhaust turbine 31, reduction gear box 32 and alternator 33, alternator 33 is connected with reduction gear box 32, reduction gear box 32 is connected with exhaust turbine 31, exhaust turbine 31 is communicated with the exhaust header 4 of the waste gas of collecting main frame 1 generation by pipeline 311, between exhaust header 4 and pipeline 311, switch valve 5 is installed also.During work, switch valve 5 is opened, and the waste gas in exhaust header 4 arrives exhaust turbine 31 through pipeline 311, and the turbine acting of exhaust turbine 31 is produced rotation function, slowing down through reduction gear box 32 afterwards passes to alternator 33, by alternator 33, kinetic energy is converted to electric energy output.
For further reducing the vessel motion cost, realize energy-conservation purpose, the power generation system of Container ship of the present invention also can comprise an axle generator 2 that is connected with main frame 1 output shaft, it is by output shaft drive of main frame 1, and the kinetic energy more than needed of main frame 1 is converted to electric energy.Because main frame 1 provides the power of power usually to be no more than 90% of its fullcharging power to Shipping, so main frame 1 all has the margin of power more than 10% usually, axle generator 2 is by rationally using this Partial Power, greatly save energy loss, reduced the vessel motion cost.
In addition, the part waste gas of main frame 1 discharging also gives exhaust boiler 7 heating by exhaust header 4 through pressurized machine 6, produce steam with the waste gas residual heat that utilizes main frame 1 discharging, this steam can be used for the cargo tank heating, the lubricating oil heating, subsidiary engine take steam as power on oil carrier and crewman, passenger's needs in life, thus further realize energy-conservation purpose.
These are only better possible embodiments of the present invention, and unrestricted protection scope of the present invention, the equivalent structure that all utilizations specification of the present invention and accompanying drawing content have been done changes, and all is included in protection scope of the present invention.
