[0031] like Figure 1-4 As shown: A ship energy configuration system based on magnetic levitation low-temperature waste heat power generation technology includes a magnetic levitation low-temperature waste heat power generation module 1. The power output terminal of the magnetic levitation low-temperature waste heat power generation module 1 is connected to a magnetic levitation chiller module 2 and a magnetic levitation heat pump module 3. The magnetic levitation low-temperature waste heat power generation module 1, the magnetic levitation chiller module 2, and the magnetic levitation heat pump module 3 are all connected to a ship energy system 4 and a seawater circulation system 7. The magnetic levitation heat pump module 3 is connected to the input terminals of a ship turbine flue gas system 5 and a cylinder liner water heat exchange system 6. The output pipelines of the ship turbine flue gas system 5 and the cylinder liner water heat exchange system 6 pass sequentially through the magnetic levitation heat pump module 3 and the magnetic levitation low-temperature waste heat power generation module 1 and are discharged from the ship turbine flue gas system discharge terminal 51 and the cylinder liner water heat exchange system discharge terminal 61.

[0032] The magnetic levitation low-temperature waste heat power generation module 1 includes a magnetic levitation low-temperature waste heat generator set 101. The magnetic levitation low-temperature waste heat generator set 101 and the seawater circulation system 7 form a closed loop through pipelines. The seawater circulation system 7 is used to cool the magnetic levitation low-temperature waste heat generator set 101.

[0033] One output end of the seawater circulation system 7 is connected to a first cylinder liner water heat exchanger 103. One output end of the first cylinder liner water heat exchanger 103 is connected to the input end of the magnetic levitation low-temperature waste heat generator set 101 through a power generation water inlet pipe 1011. A first temperature sensor 1012 is installed on the power generation water inlet pipe 1011. The output end of the first temperature sensor 1012 is connected to a first flue gas heat exchanger 102 through a first circulating waste heat water inlet pipe 1013 on the power generation water inlet pipe 1011. The output end of the first flue gas heat exchanger 102 is connected to the input end of the magnetic levitation low-temperature waste heat generator set 101.

[0034] A first control component 1021 is installed on the power generation water inlet pipe 1011 at the output end of the first temperature sensor 1012, and a second control component 1022 is installed on the first circulating waste heat water inlet pipe 1013. The first control component 1021 and the second control component 1022 are electrically connected to the first temperature sensor 1012, and the valves of the first control component 1021 and the second control component 1022 are initially in a closed state.

[0035] The output end of the magnetic levitation low-temperature waste heat generator set 101 is connected to the first cylinder liner water heat exchanger 103 through the power generation water outlet pipe 1014. The power generation water outlet pipe 1014 is equipped with a first circulating water pump 1015 and a second temperature sensor 1018. The output end of the second temperature sensor 1018 is connected to the input end of the first flue gas heat exchanger 102 through the second circulating waste heat inlet pipe 1016 on the power generation water outlet pipe 1014.

[0037] In use, the circulating water in the seawater circulation system 7 flows through the first cylinder liner water heat exchanger 103 to absorb the low-temperature waste heat from the cylinder liner water, and flows out of the first cylinder liner water heat exchanger 103 through the first circulating waste heat inlet pipe 1013. After the first temperature sensor 1012 judges, if the temperature of the circulating water is higher than 80°C, the first control component 1021 is controlled to open, and the circulating water enters the magnetic levitation low-temperature waste heat generator set 101 to generate electricity.

[0038] If the temperature of the circulating water is determined by the first temperature sensor 1012 to be below 80°C, the second control component 1022 will be turned on, and the circulating water will enter the first flue gas heat exchanger 102 for heat exchange and temperature increase. Then the circulating water will enter the magnetic levitation low temperature waste heat generator set 101 to generate electricity.

[0039] After the circulating water is cooled by the magnetic levitation low-temperature waste heat generator set 101, it is discharged from the generator outlet pipe 1014 by the first circulating water pump 1015 and then to the second temperature sensor 1018. If the temperature of the circulating water is higher than 50°C, the fourth control component 1024 is activated and the water enters the first flue gas heat exchanger 102 for heat exchange and temperature increase. If the temperature of the circulating water is lower than 50°C, the third control component 1023 is activated and the water enters the first cylinder liner water heat exchanger 103. Then, the water returns from the first cylinder liner water heat exchanger 103 to the seawater circulation system 7 for recirculation.

[0040] The magnetic levitation chiller module 2 includes a plate heat exchanger 202, which is connected to the seawater circulation system 7 via a circulation pipeline. The outlet of the plate heat exchanger 202 is connected to a first circulating chilled water inlet pipe 2011, and a third temperature sensor 2012 is installed on the first circulating chilled water inlet pipe 2011.

[0045] In use, the seawater circulation system 7 will still input the plate heat exchanger 202 to cool and exchange the circulating water in the plate heat exchanger 202. The circulating water in the plate heat exchanger 202 flows out through the first circulating cold water inlet pipe 2011 and passes through the third temperature sensor 2012. The third temperature sensor 2012 judges the temperature of the circulating water. If the temperature of the circulating water meets the temperature requirements of the air conditioning chilled water supply terminal (inlet water 7℃, outlet water 12℃), it controls the fifth control component 2021 valve to open and enter the ship energy system 4 for cooling. After the ship energy system 4 utilizes the cold energy of the circulating water, it is discharged through the circulating cold water outlet pipe 2014. At this time, the seventh control component 2023 valve opens, and under the action of the second circulating water pump 2015, it returns to the plate heat exchanger 202 for cooling and heat exchange again.

[0046] If the circulating water temperature does not meet the requirements, the sixth control component 2022 is opened to enter the magnetic levitation chiller unit 201 for cooling. After the circulating water temperature drops to the required temperature of the air conditioning chilled water supply terminal, it is discharged from the magnetic levitation chiller unit 201 and enters the ship energy system 4 for cooling. After the ship energy system 4 utilizes the cold energy of the circulating water, it is discharged through the circulating chilled water outlet pipe 2014. At this time, the valve of the seventh control component 2023 is closed, and the circulating water returns to the magnetic levitation chiller unit 201 for cooling.

The output end of the second flue gas heat exchanger 302 is connected to the first thermal energy outlet pipe 3011 through a pipeline.

[0050] In use, the circulating seawater of the seawater circulation system 7 enters the second cylinder liner water heat exchanger 303 for heat exchange. The temperature of the circulating seawater is determined by the fourth temperature sensor 3012 on the first heat energy outlet pipe 3011. If the temperature meets the requirements of the ship energy system 4, the eighth control component 3014 and the ninth control component 3016 are activated, and the circulating water enters the ship energy system 4 for heating. After the heat energy of the circulating seawater is utilized by the ship energy system 4, it returns to the second cylinder liner water heat exchanger 303 through the second heat energy outlet pipe 3021 under the action of the third circulating water pump 3024.

[0051] If the circulating seawater does not meet the temperature requirements of the ship's energy system 4, then the eighth control component 3014 and the thirteenth control component 3023 are shut down and the tenth control component 3015 and the fourteenth control component 3026 are turned on. The circulating seawater enters the second flue gas heat exchanger 302 for heat exchange, and then enters the ship's energy system 4 through the first heat energy outlet pipe 3011 for heating. The heat energy of the circulating seawater is used by the ship's energy system 4 and then returns to the second flue gas heat exchanger 302 for heat exchange.

[0052] If the circulating seawater does not meet the temperature requirements of the ship energy system 4 and the temperature is too low, then the eighth control component 3014, the tenth control component 3015 and the eleventh control component 3018 are turned on and the eleventh control component 3018, the thirteenth control component 3023 and the fourteenth control component 3026 are turned off. The circulating seawater enters the magnetic levitation heat pump unit 301 after passing through the second flue gas heat exchanger 302 for heating, and then enters the ship energy system 4 for heating.
