Problems solved by technology
Since the output power of the main engine of the ship will also decrease when the load is low, in this case, the flow rate of the exhaust gas generated by the main engine will decrease, and when the exhaust gas turbine drives the waste heat recovery generator to generate power, the output power is very small, usually It will be much smaller than the output power of a generator set. In this case, the waste heat recovery generator driven by the exhaust gas turbine cannot replace the original generator set on the ship, and the energy saving effect is not significant.

Embodiment Construction
[0022] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.
[0023] Such as figure 1 As shown, this embodiment discloses an energy-saving power generation device for ships, including a waste heat recovery generator 5, an exhaust gas turbine 2, a steam turbine 4, an exhaust gas boiler 3, a first reduction gearbox 6 and a second reduction gearbox 7 . The exhaust gas turbine 2 and the steam turbine 4 can jointly drive the waste heat recovery generator 5 to generate electricity.

The invention provides an energy-saving generation device for a ship and the ship with the energy-saving generation device for the ship. The energy-saving generation device for the ship comprises a waste heat recycling generator, a waste gas turbine, a steam turbine, a waste gas boiler, a first speed reduction gearbox and a second speed reduction gearbox. A rotary shaft of the steam turbine is connected with the waste heat recycling generator through the first speed reduction gearbox. A rotary shaft of the waste gas turbine and the rotary shaft of the steam turbine are connected through the second speed reduction gearbox. According to the energy-saving generation device for the ship, the waste heat recycling generator is driven by the steam turbine and the waste gas turbine together. When the output power of a main machine is about below 50% of the load, the steam turbine can still provide power for the generator, and the situation that the output power of the waste heat recycling generator is cut off when the main machine has low loads is avoided. When the main machine has high loads, the waste heat recycling generator can replace an auxiliary generator set, and a remarkable energy-saving effect is achieved.
Description
technical field [0001] The present invention relates to an energy-saving power generation device for ships, and also relates to a ship with the energy-saving power generation device for ships. Background technique [0002] Due to the large power of the main engine of modern large ships, the flow of high-temperature exhaust gas generated when the main engine is working is also very large. The exhaust gas contains a lot of heat energy. How to make full use of this heat energy has a great impact on the energy saving, environmental protection and cost reduction of the ship. big meaning. [0003] Some ships are equipped with an exhaust gas boiler and an exhaust gas turbine. The exhaust gas turbine can drive a waste heat recovery generator to generate electricity, while the exhaust gas boiler can use the waste heat of the exhaust gas to produce water vapor to meet the steam consumption required for ship operation. Since the output power of the main engine of the ship will also de...
