Description

Technical Field

[0001] This utility model relates to the field of marine turbocharger technology, and in particular to a test device and test chamber for a green ammonia fuel marine turbocharger. Background Technology

[0002] With the application of green and low-carbon energy in the field of marine propulsion, such as ammonia and methanol fuels, traditional fuels are gradually being replaced. However, the application of new fuels brings both opportunities and challenges to marine turbochargers. On the one hand, ammonia fuel, whose main component is NH3, can be synthesized from nitrogen in the air and hydrogen in water. When completely burned, the products are pure and carbon-free, and ammonia can be directly burned to provide clean energy. On the other hand, incomplete combustion of ammonia can lead to leakage, which can enter the air and cause poisoning if inhaled, and will also have an impact on the environment.

[0003] Currently, there is limited research on testing equipment and applications for marine ammonia-fueled turbochargers. This patent, based on the principles of "safety and operability," designs a green testing equipment and laboratory for marine ammonia-fueled turbochargers, filling a gap and laying the foundation and providing testing guidance for ammonia-fueled marine turbochargers. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a green ammonia fuel marine turbocharger test device and test chamber with good safety and operability.

[0005] The purpose of this utility model is achieved as follows: A green ammonia fuel marine turbocharger test device is disclosed. The marine turbocharger has a combustion inlet pipe and a combustion exhaust pipe, and includes a fuel chamber. The fuel chamber has a first feed end, a second feed end, and an exhaust end. The first feed end of the fuel chamber is connected to an ammonia inlet branch. The ammonia inlet branch includes an ammonia production device, an ammonia stabilizing valve, and an ammonia stabilizing bottle connected in sequence through pipelines. The ammonia stabilizing bottle is connected to the first feed end of the fuel chamber. The second feed end of the fuel chamber is connected to the fuel chamber through a pipeline. The fuel chamber has a fuel supply system for supplying fuel to the combustion chamber. The exhaust end of the fuel chamber is connected in sequence to the intake valve and the fuel inlet pipe of the marine turbocharger via a pipeline. The exhaust pipe of the marine turbocharger is connected in sequence to the exhaust valve, cooling separator, separation valve, and ammonia filter via a pipeline. The cooling separator is used to cool the products after fuel combustion and separate the products after incomplete combustion of ammonia. The ammonia filter is used to filter the products after incomplete combustion of ammonia and separate pure ammonia.

[0006] Preferably, the ammonia filter is connected to the ammonia generating device via an ammonia return valve, enabling the ammonia generating device to recover unburned ammonia.

[0007] A test chamber based on a green ammonia fuel marine turbocharger test device includes a chamber body, in which the green ammonia fuel marine turbocharger test device is located. The chamber body has a door, the position of which corresponds to the marine turbocharger. A top frame is provided on the top of the chamber body, and a spray device is provided on the top frame. An ammonia alarm is provided on the turbocharger. The ammonia alarm is used to detect ammonia gas leakage, and the spray device is used to spray water on the green ammonia fuel marine turbocharger test device.

[0008] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: This invention fills the gap in domestic testing equipment and testing rooms for ammonia-fueled marine turbochargers, fully considering safety and operability, and laying the foundation and providing testing guidance for ammonia-fueled marine turbocharger testing.

Detailed Implementation

[0011] See Figures 1-3 This is a test device for a green ammonia fuel marine turbocharger. The marine turbocharger has a fuel inlet pipe 12 and a fuel exhaust pipe 10. Its features include a fuel chamber 16, which has a first feed end, a second feed end, and an exhaust end. The first feed end of the fuel chamber 16 is connected to an ammonia inlet branch, which includes an ammonia production device 1, an ammonia stabilizing valve 19, and an ammonia stabilizing bottle 18 connected sequentially via pipes. The ammonia stabilizing bottle 18 is connected to the first feed end of the fuel chamber 16. The second feed end of the fuel chamber 16 is connected to the fuel chamber 16 via a pipe. The fuel chamber 16 has a fuel supply system (including a fuel pump) for supplying fuel to a combustion chamber 15. The exhaust end of the fuel chamber 16 is connected in sequence via pipes to the intake valve 14 and the fuel inlet pipe 12 of the marine turbocharger 7. The exhaust pipe 10 of the marine turbocharger 7 is connected in sequence via pipes to the exhaust valve 9, the cooling separator 24, the separator valve 5, and the ammonia filter 4. The cooling separator 24 is used to cool the products after fuel combustion and separate the products of incomplete ammonia combustion. The ammonia filter 4 is used to filter the products of incomplete ammonia combustion and separate pure ammonia. The ammonia filter 4 is connected to the ammonia production device 1 through the ammonia return valve 2, enabling the ammonia production device 1 to recover incompletely burned ammonia.

[0012] A test chamber based on a green ammonia fuel marine turbocharger test device includes a chamber body 21, in which the green ammonia fuel marine turbocharger test device is located. The chamber body 21 has a door 25, the position of which corresponds to the marine turbocharger 7. A top frame 23 is provided on the top of the chamber body 21, and a spray device 22 is provided on the top frame 23. An ammonia alarm 11 is provided on the turbocharger 7. The ammonia alarm 11 is used to detect ammonia gas leakage. The spray device 22 is used to spray water on the green ammonia fuel marine turbocharger test device to dilute the ammonia in the air inside the chamber body 21.

[0013] Specifically: This utility model includes: an ammonia production device 1, which generates ammonia and recovers ammonia after incomplete combustion; a combustion chamber 15, which serves as the combustion site for fuel oil and ammonia; a fuel oil chamber 16, which stores fuel oil and serves as an igniter for ammonia; an ammonia stabilizing bottle 18, which stabilizes the pressure and flow rate of ammonia to prevent it from failing to burn in the combustion chamber 15; a cooling separator 24, which cools the products after fuel oil combustion and separates the products after incomplete combustion of ammonia; an ammonia filter 4, which filters the products after incomplete combustion of ammonia to separate pure ammonia; and an ammonia stabilizing valve 19, an inlet valve 14, an exhaust valve 9, a separation valve 5, and a return ammonia valve 2 to control fluid flow. All components can utilize existing components with the same functions.

[0014] Before the test begins, door 25 should be closed. Fuel from fuel chamber 16 enters combustion chamber 15 and burns continuously. Then, ammonia produced in ammonia production device 1 enters ammonia stabilization bottle 18 through ammonia outlet pipe 20 and ammonia stabilization valve 19. After the pressure stabilizes, it enters combustion chamber 15 through intermediate pipe 17 for combustion. The exhaust gas from the combustion of ammonia in ammonia production device 1 and fuel in fuel chamber 16 enters fuel inlet pipe 12 of marine turbocharger 7 through intake pipe 13 via intake valve 14. Finally, it is discharged from exhaust pipe 10 of marine turbocharger 7, enters cooling separator 24 through exhaust valve 9 and exhaust pipe 8 for exhaust gas cooling, and separates the initial ammonia mixture. The mixture enters ammonia filter 4 through separation pipe 6 and separation valve 5 to filter out pure ammonia. Finally, it enters ammonia production device 1 through return pipe 3 and return valve 2 for recycling.

[0015] If an ammonia leak occurs during the test, the ammonia alarm 11 in the marine turbocharger 7 will sound an alarm. At the same time, the sprinkler device 22 on the top frame 23 of the chamber 21 will start spraying water to dilute the ammonia in the air. The intake valve 14, exhaust valve 9, separation valve 5, and ammonia return valve 2 will be closed until the ammonia alarm 11 stops sounding. Then the door 25 will be opened and the operator will enter the room.

[0016] After the test is completed, close the exhaust valve 9, stop fuel supply to the fuel chamber 16, and continue combustion in the combustion chamber 15 until the pressure in the ammonia stabilization bottle 18 is 0. After waiting for 30 minutes, close the intake valve 14, exhaust valve 9, separation valve 5, and ammonia return valve 2 in sequence.

[0017] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
