Description

Ship ORC waste heat power generation system and ship

[0001] This application claims priority to Chinese patent application No. CN 202411917636.2, filed on December 23, 2024, entitled "Marine ORC Waste Heat Power Generation System and Ship", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates generally to the technical field of ship waste heat power generation, and more specifically to a ship ORC waste heat power generation system and a ship. Background Technology

[0003] Ships generate a significant amount of waste heat during operation. Waste heat power generation technology based on the Organic Rankine Cycle (ORC) is a common method for utilizing waste heat.

[0004] In ORC waste heat power generation systems, the design of the expander impeller is affected by the heat source temperature. When the heat source temperature is high, the pressure before expansion is high; therefore, designing the impeller according to this expansion pressure will achieve optimal aerodynamic efficiency. Conversely, when the heat source temperature is low, the pressure before expansion decreases, and the impeller needs to be designed according to the low-pressure expansion pressure to achieve optimal aerodynamic efficiency. Ships are affected by factors such as navigation area and season, resulting in an unstable supply of high-grade heat sources (such as steam). This necessitates switching between low-temperature and high-temperature heat sources, leading to unstable pressure at the expander impeller front end and impacting power generation efficiency.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0036] Figure 1 illustrates a ship ORC waste heat power generation system 200 according to a specific embodiment of this application. The ship ORC waste heat power generation system 200 includes a generator 100, a first evaporator 110, a second evaporator 120, a first regulating valve 130, a second regulating valve 140, and a control device (not shown in the figure).

[0037] The generator 100 includes a first impeller 101 and a second impeller 102. The operating temperature range for the first impeller 101 is at least partially higher than that for the second impeller 102. A first evaporator 110 is connected to the first impeller 101 via a first conduit 170 and to the second impeller 102 via a second conduit 180. The first evaporator 110 is used to connect to a high-temperature heat source of the ship. The second evaporator 120 is used to connect to a low-temperature heat source of the ship and is connected to the first evaporator 110.

[0038] A first regulating valve 130 is located in a first pipeline 170. A second regulating valve 140 is located in a second pipeline 180. A control device is electrically connected to the first regulating valve 130 and the second regulating valve 140, respectively. The control device is configured to control the opening degree of the first regulating valve 130 and the second regulating valve 140 according to the current heat source type of the ship.

[0039] According to the ship ORC waste heat power generation system 200 of this application, the control device adjusts the opening of the first regulating valve 130 and the second regulating valve 140 according to the heat source type of the ship, thereby adjusting the ratio of working fluid delivered to the first impeller 101 and the second impeller 102 respectively, so that the first impeller 101 and the second impeller 102 of the generator 100 operate within the corresponding suitable power generation operating temperature range, thereby enabling the ship ORC waste heat power generation system to have good power generation efficiency under different heat source types.

[0040] Optionally, within the shipboard ORC waste heat power generation system 200, heat is transferred through the power generation medium D4, which expands and performs work on either the first impeller 101 or the second impeller 102, causing them to rotate and thus converting thermal energy into mechanical energy. The generator 100 contains a rotor 103, which is coaxially arranged with the first impeller 101 and the second impeller 102. The rotor 103 is positioned between the first impeller 101 and the second impeller 102. When the first impeller 101 or the second impeller 102 rotates, it drives the rotor 103 to rotate, thereby cutting magnetic field lines within the generator 100 to generate electricity, thus converting mechanical energy into electrical energy.

[0041] Optionally, the first impeller 101 is designed for high-temperature power generation, while the second impeller 102 is designed for low-temperature power generation. Because the input conditions (temperature and expansion pressure of the input power generation medium) are different, the diameters and blade shapes of the first impeller 101 and the second impeller 102 are different, resulting in different impeller profiles and flow channels. Furthermore, the expansion volutes at both ends of the generator 100 for mounting the first impeller 101 and the second impeller 102 need to be designed separately based on the impeller and flow channel to ensure good power generation efficiency of the generator 100.

[0042] Specifically, in this embodiment, the first impeller 101 is suitable for power generation operating conditions with a temperature range of 120-150°C and an expansion pressure range of 15-30 bar. The second impeller 102 is suitable for power generation operating conditions with a temperature range of 75-90°C and an expansion pressure range of 6-9 bar.

[0043] Optionally, referring to Figure 1, the marine ORC waste heat power generation system 200 further includes a working fluid pump 160 and a condenser 150. The condenser 150 is connected to the first impeller 101 and the second impeller 102. The cooling medium D3 introduced into the condenser 150 exchanges heat with the power generation working fluid D4 entering the condenser 150, thereby condensing the gaseous power generation working fluid D4 from the first impeller 101 or the second impeller 102 into a liquid state. The working fluid pump 160 is connected to both the condenser 150 and the second evaporator 120. When the working fluid pump 160 is started, the power generation working fluid D4 at the condenser 150 enters the second evaporator 120 through the working fluid pump 160, realizing the circulation of the power generation working fluid D4 within the marine ORC waste heat power generation system.

[0044] As shown in Figures 1 and 2, optionally, the first evaporator 110 is connected to the high-temperature heat source 301 via a pipeline and is equipped with a high-temperature heat source inlet regulating valve 111. The medium generated by the high-temperature heat source 301 (e.g., steam, hereinafter referred to as high-temperature heat source medium D1) is transmitted to the first evaporator 110 via the pipeline, thereby exchanging heat with the power generation working fluid D4 passing through the first evaporator 110, allowing the power generation working fluid D4 to absorb the heat from the high-temperature heat source medium D1. Similarly, the second evaporator 120 is connected to the low-temperature heat source 302 via a pipeline and is equipped with a low-temperature heat source inlet regulating valve 121. The medium generated by the low-temperature heat source 302 (e.g., steam, hereinafter referred to as low-temperature heat source medium D2) is transmitted to the second evaporator 120 via the pipeline, thereby exchanging heat with the power generation working fluid D4 passing through the second evaporator 120, allowing the power generation working fluid D4 to absorb the heat from the low-temperature heat source medium D2.

[0045] To determine the type of heat source occurring during ship operation, the ship's ORC waste heat power generation system 200 also includes a detection device. The detection device includes a first sensing mechanism 191 and a second sensing mechanism 192. The first sensing mechanism 191 is used in a pipeline between the high-temperature heat source 301 and the first evaporator 110 to detect whether a high-temperature heat source medium D1 is transferred to the first evaporator 110. The second sensing mechanism 192 is used in a pipeline between the low-temperature heat source and the second evaporator 120 to detect whether a low-temperature heat source medium D2 is transferred to the second evaporator 120. Both the first sensing mechanism 191 and the second sensing mechanism 192 are electrically connected to a control device, allowing the control device to control the opening degree of the first regulating valve 130 and the second regulating valve 140 according to the ship's heat source type.

[0046] Optionally, the first sensing mechanism 191 includes a first pressure sensor 193 and a first flow meter 194. The first pressure sensor 193 is used to detect the pressure of the high-temperature heat source medium D1 delivered from the high-temperature heat source 301 to the first evaporator 110. The first flow meter 194 is used to detect the flow rate of the high-temperature heat source medium D1 delivered from the high-temperature heat source 301 to the first evaporator 110. Both the first pressure sensor and the first flow meter are electrically connected to a control device, so that the control device can determine the condition of the high-temperature heat source 301 based on the pressure and flow rate of the high-temperature heat source medium D1 in the pipeline between the high-temperature heat source 301 and the first evaporator 110.

[0047] Similarly, the second sensing mechanism 192 includes a second pressure sensor 195 and a second flow meter 196. The second pressure sensor 195 is used to detect the pressure of the low-temperature heat source medium D2 delivered from the low-temperature heat source 302 to the second evaporator 120. The second flow meter 196 is used to detect the flow rate of the low-temperature heat source medium D2 delivered from the low-temperature heat source 302 to the second evaporator 120. Both the second pressure sensor 195 and the second flow meter 196 are electrically connected to a control device, so that the control device can determine the condition of the low-temperature heat source 302 based on the pressure and flow rate of the low-temperature heat source medium D2 in the pipeline between the low-temperature heat source 302 and the second evaporator 120.

[0048] The following describes how the control device specifically controls the first regulating valve 130 and the second regulating valve 140.

[0049] The control device is configured as follows:

[0050] When the second sensing mechanism 192 detects the medium while the first sensing mechanism 191 does not detect the medium, that is, when the ship only has a low-temperature heat source 302, the control device controls the second regulating valve 140 to open, so that the power generation working medium D4 heated by the second evaporator 120 can enter the second impeller 102. At this time, the generator 100 is suitable for power generation under the condition of low-temperature heat source.

[0051] When both the first sensing mechanism 191 and the second sensing mechanism 192 detect the medium, that is, when the ship has both a high-temperature heat source 301 and a low-temperature heat source 302, the control device controls the first regulating valve 130 to open, so that the power generation working medium D4 heated by the second evaporator 120 and the first evaporator 110 can enter the first impeller 101. At this time, the generator 100 is suitable for power generation under the condition of high-temperature heat source.

[0052] Specifically, when the second sensing mechanism 192 detects a medium while the first sensing mechanism 191 does not, that is, when the ship only has a low-temperature heat source 302, the control device controls the opening of the second regulating valve 140 to be greater than the opening of the first regulating valve 130, so that the power generation medium D4 entering the second impeller 102 is more than the power generation medium D4 entering the first impeller 101, making the generator 100 more suitable for power generation conditions of low-temperature heat sources.

[0053] Furthermore, the control device is configured such that when the second sensing mechanism 192 detects the medium while the first sensing mechanism 191 does not detect the medium, the control device controls the ratio of the opening of the second regulating valve 140 to the opening of the first regulating valve 130 to be 4:1, so that most of the power generation medium D4 does work on the second impeller 102, thereby enabling the generator 100 to have good power generation efficiency.

[0054] Specifically, when both the first sensing mechanism 191 and the second sensing mechanism 192 detect the medium, that is, when the ship has both a high-temperature heat source 301 and a low-temperature heat source 302, the control device controls the opening of the first regulating valve 130 to be greater than the opening of the second regulating valve 140, so that the amount of power generation medium D4 entering the first impeller 101 is greater than the amount of power generation medium D4 entering the second impeller 102, making the generator 100 more suitable for power generation conditions with high-temperature heat sources.

[0055] Furthermore, the control device is configured such that when both the first sensing mechanism 191 and the second sensing mechanism 192 detect the medium, the control device controls the ratio of the opening of the first regulating valve 130 to the opening of the second regulating valve 140 to 4:1, so that most of the power generation medium D4 does work on the first impeller 101, thereby enabling the generator 100 to have good power generation efficiency.

[0056] In summary, when the detection device detects that the ship has only a low-temperature heat source 302, the opening of the first regulating valve 130 decreases, the opening of the second regulating valve 140 increases, and the working fluid pump 160 operates at low frequency. At this time, the power generation working fluid D4, after being pressurized by the working fluid pump 160, first passes through the second evaporator 120, where it exchanges heat with the low-temperature heat source 302 to reach a saturated gaseous state. Then it passes through the first evaporator 110 (without heat exchange). Most of the power generation working fluid D4 enters the second impeller 102 through the second regulating valve 140 to expand and do work, while a small portion of the power generation working fluid D4 enters the first impeller 101 through the first regulating valve 130 to expand and do work. The expanded power generation working fluid D4 enters the condenser 150, exchanges heat with the cooling water, condenses, and then re-enters the working fluid pump 160 for circulation.

[0057] When the detection device detects that the ship simultaneously has a high-temperature heat source 301 and a low-temperature heat source 302, the opening of the first regulating valve 130 is increased, the opening of the second regulating valve 140 is decreased, and the working fluid pump 160 operates at high frequency. The power generation working fluid D4, after being pressurized by the working fluid pump 160, first passes through the second evaporator 120, exchanging heat with the low-temperature heat source 302. At this time, the second evaporator 120 only serves to preheat the power generation working fluid D4; no phase change occurs in the working fluid D4. The preheated power generation working fluid D4 enters the first evaporator 110 to exchange heat with the high-temperature heat source until it reaches a high-pressure saturated gaseous state. Subsequently, most of the power generation working fluid D4 enters the first impeller 101 through the first regulating valve 130 to expand and perform work, while a small portion enters the second impeller 102 through the second regulating valve 140 to expand and perform work. The expanded power generation working fluid D4 enters the condenser 150 to exchange heat with cooling water and condenses, then re-enters the working fluid pump 160 for circulation.

[0058] This application also provides a ship. As shown in FIG2, in a specific embodiment, the ship 300 includes the aforementioned ship ORC waste heat power generation system 200, a high-temperature heat source 301, and a low-temperature heat source 302. The ship according to this application has a ship ORC waste heat power generation system that can fully utilize heat sources within the ship at multiple temperature ranges, resulting in high power generation efficiency.
