Description

Technical Field

[0001] This utility model relates to the field of marine vessel equipment technology, and in particular to a new type of marine liquid ammonia processing vessel. Background Technology

[0002] Currently, several ammonia-powered offshore vessels have been developed both domestically and internationally. These vessels are primarily found in mainstream ship types such as oil tankers, container ships, and bulk carriers. Ammonia-powered offshore vessels generate hydrogen energy through the cracking of liquid ammonia, which then provides their power. Ammonia is a carbon-free, hydrogen-rich gas, and theoretically, its hydrogen storage density is higher than that of liquid hydrogen. Furthermore, ammonia liquefaction, storage, and transportation technologies are mature, and ammonia and hydrogen do not chemically react under normal conditions. Therefore, ammonia is safer and easier to store and transport than liquid hydrogen. However, current ammonia-powered offshore vessels cannot simultaneously store, transfer, load, unload, and crack ammonia to produce hydrogen at sea. Therefore, this paper proposes a reasonable deployment method for ammonia-powered offshore vessels to address these issues. Utility Model Content

[0003] In view of this, in order to solve the problem that current ammonia-powered offshore vessels cannot simultaneously store, transfer, load and unload, and crack ammonia to produce hydrogen at sea, the present invention provides a new type of offshore liquid ammonia processing vessel.

Each liquid ammonia pyrolyzer is connected to its corresponding liquid ammonia storage tank to pyrolyze liquid ammonia to generate hydrogen. The ship's hull is equipped with a hydrogen energy storage processor, which is connected to each of the liquid ammonia pyrolyzers to compress and store the generated hydrogen. The ship's hull is also equipped with a drive assembly, which is connected to each of the liquid ammonia storage tanks to obtain ammonia energy to drive the ship's hull.

[0006] Furthermore, the drive assembly includes an ammonia generator and several azimuth thrusters, wherein each of the azimuth thrusters is respectively disposed on the bow and stern of the hull and has the same driving direction.

[0007] Furthermore, a liquid ammonia preparation chamber is provided between the ammonia generator and each of the liquid ammonia storage tanks.

Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 3 The present invention provides a novel marine liquid ammonia processing vessel, comprising a hull 1.

[0022] In this embodiment, the bow and stern lines of the hull 1 are similar, with the left side being the stern and the right side being the bow. When the hull 1 is sailing normally, the bow of the hull 1 is in front and the stern is behind.

[0023] An upper living area 9 is built on the deck at the bow of the hull 1, which is used for the crew to rest; a bridge 10 is built at the upper end of the upper living area 9, which is used for driving the hull 1.

[0024] Meanwhile, rescue areas 11 are provided at the ends of the bow and stern of the hull 1, and various rescue equipment are provided in each rescue area 11 to carry out rescue when needed.

[0025] Furthermore, several liquid ammonia storage tanks 2 are provided inside the hull 1. In this embodiment, there are three liquid ammonia storage tanks 2, and each liquid ammonia storage tank 2 is evenly installed in the inner cavity of the hull 1. Several liquid ammonia crackers 3 are provided above each liquid ammonia storage tank 2 and on the deck of the hull 1. Each liquid ammonia cracker 3 corresponds one-to-one with each liquid ammonia storage tank 2. Each liquid ammonia cracker 3 can be detachably fixed on the deck and communicates with the corresponding liquid ammonia storage tank 2 so that the liquid ammonia in the corresponding liquid ammonia storage tank 2 can be cracked into hydrogen when needed. At the same time, each liquid ammonia cracker 3 can be easily disassembled when not in use.

[0026] A hydrogen energy storage processor 4 is provided on the hull 1. In this embodiment, the hydrogen energy storage processor 4 is located at the stern of the hull 1 and is connected to each liquid ammonia cracker 3 so as to compress and store the hydrogen generated after the liquid ammonia is cracked in each liquid ammonia cracker 3.

[0027] Furthermore, the hull 1 is also equipped with a drive assembly, which is connected to each liquid ammonia storage tank 2 to obtain ammonia energy to drive the hull 1. In this embodiment, the drive assembly includes four azimuth thrusters 5 and an ammonia generator 6. The four azimuth thrusters 5 are evenly arranged on the bow and stern of the hull 1 and drive in the same direction. The ammonia generator 6 is located at the bow of the hull 1, and one end of the ammonia generator 6 is connected to each liquid ammonia storage tank 2, and the other end is connected to each azimuth thruster 5. In this way, when the hull 1 needs to be driven, the ammonia energy in each liquid ammonia storage tank 2 can be pre-treated by the ammonia generator 6 and then transported to each azimuth thruster 5 for combustion, thereby generating power to drive the hull 1.

[0028] Furthermore, a liquid ammonia preparation chamber 15 is connected to one end of the ammonia generator 6 that is connected to each liquid ammonia storage tank 2. When the hull 1 needs to be driven, the liquid ammonia in each liquid ammonia storage tank 2 enters the liquid ammonia preparation chamber 15 for processing and vaporization before entering the ammonia generator 6, thereby driving each azimuth thruster 5. It should be noted that in actual working conditions, the liquid ammonia preparation chamber 15 is matched with the ammonia generator 6. When ammonia energy needs to be used, the liquid ammonia preparation chamber 15 first processes the liquid ammonia in each liquid ammonia storage tank 2 to form gaseous ammonia, and makes the gaseous ammonia meet the usage requirements of the ammonia generator 6 before allowing the gaseous ammonia to enter the ammonia generator 6 for use.

[0029] The hull 1 is also equipped with a liquid ammonia storage preprocessor 7. One end of the liquid ammonia storage preprocessor 7 is connected to an external liquid ammonia source through a conveying pipe 8, and the other end is connected to each liquid ammonia storage tank 2. In this way, liquid ammonia can be injected into each liquid ammonia storage tank 2 through an external liquid ammonia source, or the liquid ammonia in each liquid ammonia storage tank 2 can be transported to the required equipment when needed.

[0030] Furthermore, a smoke exhaust integrator 14 is provided at the bow of the hull 1, and the smoke exhaust integrator 14 is connected to various energy-consuming equipment on the hull 1 for exhaust gas discharge; several positioning and mooring systems 13 are provided at both the bow and stern of the hull 1, and each positioning and mooring system 13 is used to position the hull 1 when needed; several berthing energy-absorbing fenders 12 are provided along the edge of the hull 1 to reduce collisions between the hull 1 and other vessels when the hull 1 berths.

[0031] The working mode of a novel offshore liquid ammonia processing vessel in this embodiment is as follows: liquid ammonia can be injected into the liquid ammonia storage tank 2 through the cooperation of the conveying pipeline 8 and the liquid ammonia storage preprocessor 7, and the liquid ammonia in the liquid ammonia storage tank 2 can also be discharged to the required equipment when needed; the azimuth thruster 5 and the ammonia generator 6 can use ammonia energy to drive the hull 1. In summary, it can use the large amount of liquid ammonia stored on its own to supply its own propulsion fuel and cracking to produce hydrogen. At the same time, it can also serve as an offshore liquid ammonia storage station to supply liquid ammonia to foreign ships, and can also sail and transport liquid ammonia on its own, with multiple functions.

It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.
