Detailed Description
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1 and 2, a marine exhaust heat recovery system includes a marine diesel engine exhaust heat recovery system and a marine diesel engine liner water exhaust heat recovery system. Fig. 1 shows an exhaust gas and waste heat recovery system of a marine diesel engine, which may include two steam turbine generators 7531/09, 7531/10, two shell-and-tube heat exchangers 7531/10, 7531/11, a hot water generator 7530/01, and the like. In fig. 1, the arrow direction indicates the flow direction of the internally circulating hot water. The exhaust gas of the marine diesel engine heats fresh water through a boiler to generate saturated steam of 7bar, and the redundant steam generates electricity through two steam turbine generators 7531/09 and 7531/10, so that the total power generation power is about 300 kW. The steam after passing through the steam turbine generator heats the internal circulation hot water of the waste heat recovery system through shell-and-tube heat exchangers 7531/10 and 7531/11, the hot water is conveyed to a hot water generator unit 7530/01, and the steam pushes a turbine to generate electricity by heating volatile media in the generator unit, wherein the total power is about 300 kW.
Fig. 2 shows a cylinder liner water waste heat recovery system for a marine diesel engine, which may include 6 waste heat recovery heat exchangers 8132/01 to 8132/06, a hot water generator set 7530/02, an air conditioner preheating heat exchanger 6355/01, an air conditioner reheating heat exchanger 6355/03, and a drinking water heater 6121/11. In fig. 2, the arrow direction indicates the flow direction of the internally circulating hot water. The cylinder liner water of the marine diesel engine heats internal circulation hot water of a waste heat recovery system through 6 waste heat recovery heat exchangers 8132/01-8132/06, the hot water is conveyed to a hot water generator unit 7530/02, and a volatile medium in the generator unit is heated to push a turbine to generate power, wherein the total power is about 300 kW; the surplus hot water heats the air conditioning system through the air conditioner preheating heat exchanger 6355/01 and the air conditioner reheating heat exchanger 6355/03 and the domestic water through the drinking water heater 6121/11.
In addition, the ship waste heat recovery system further includes heat storage pools 7532/01 and 7532/02, and heat of the heat storage pools 7532/01 and 7532/02 is derived from heat of excess steam in a sailing state of the ship. The thermal storage pools 7532/01, 7532/02 are in fluid communication with an air conditioner preheat heat exchanger 6355/01, an air conditioner reheat heat exchanger 6355/03, and a potable water heater 6121/11. In this way, the diesel engine load of the ship is reduced when the ship is in port mode, i.e. the hot water of the heat storage tank can be used to heat the air conditioning system and the domestic water without so much waste heat.
In this embodiment, the 6 waste heat recovery heat exchangers 8132/01 to 8132/06 are divided into two groups, and 3 of the groups are connected in parallel. Specifically, 3 waste heat recovery heat exchangers 8132/01 to 8132/03 are arranged in parallel in one nacelle, and the other 3 waste heat recovery heat exchangers 8132/04 to 8132/06 are arranged in parallel in the other nacelle.
