[0021] To solve the problems in the prior art, the embodiments of the present application provide a marine nitrogen generation system, Figure 1 is a structural schematic diagram of the marine nitrogen generation system provided by the embodiments of the present application, as Figure 1 shown, the system comprises: an air compression assembly 1, the air compression assembly 1 is used for receiving clean air and compressing the clean air; an air pretreatment assembly 2, the air inlet end of the air pretreatment assembly 2 is connected with the air outlet end of the air compression assembly 1, and the air pretreatment assembly 2 is used for pretreating the compressed air; a membrane separation host 3, the air inlet end of the membrane separation host 3 is connected with the air outlet end of the air pretreatment assembly 2, and the membrane separation host 3 is used for generating nitrogen from the pretreated air; a nitrogen pressure boosting assembly 4, the air inlet end of the nitrogen pressure boosting assembly 4 is connected with the air outlet end of the membrane separation host 3, and the nitrogen pressure boosting assembly 4 is used for boosting the pressure of the nitrogen; a gas supply module 5, the gas supply module 5 is used for supplying gas to a gas supply equipment; and a host computer, the host computer is used for controlling each assembly and adjusting the gas use.

[0022] The air compression assembly 1 is used for receiving clean air from the external environment and compressing the clean air. The compressed air provides a necessary gas source for subsequent nitrogen generation, and the compressed air is then sent to the air pretreatment assembly 2 for further processing.

[0023] The air pretreatment assembly 2 is used for cleaning, drying and deoiling the compressed air, so as to ensure that the air entering the membrane separation host 3 reaches the required quality standard.

[0024] The pretreated air enters the membrane separation host 3, and the nitrogen and oxygen in the air are separated by using the membrane separation technology, so as to obtain high-purity nitrogen. The membrane separation host 3 separates the gas in the air, and the output nitrogen is then boosted in the pressure boosting assembly.

[0025] The nitrogen booster assembly 4 can boost nitrogen to a certain pressure and store it according to usage requirements to meet different gas needs.

[0026] The produced nitrogen is distributed to different compartments and equipment via the gas supply module 5. The components in the system dynamically adjust the flow rate and pressure of the nitrogen according to the ship's needs to meet specific operating conditions. This process is intelligently controlled by a host computer to ensure a stable and precise nitrogen supply.

[0027] like Figure 2 Figure 3 As shown, the host computer is the core control component of the system, responsible for coordinating and regulating all components. By monitoring the system status and gas demand in real time, the host computer can automatically adjust the operating parameters of each module to ensure optimal gas supply performance and energy efficiency. The system also features intelligent mode switching, which can flexibly switch gas flow rate, pressure, and purity according to different operating modes or conditions to optimize nitrogen usage.

[0028] As an optional implementation, the air compression assembly 1 includes an air compressor 101 and an air storage tank 102; the air compressor 101 has an inlet end for receiving clean air and an outlet end connected to the inlet end of the air storage tank 102; the outlet end of the air storage tank 102 is connected to the inlet end of the air pretreatment assembly 2.

[0029] The air compression assembly 1 includes an air compressor 101 and an air storage tank 102. The air compressor 101 receives clean air at its inlet and compresses it to the required pressure. The compressed air is pressurized during compression to power subsequent processing. The air storage tank 102 stores the compressed air and balances pressure fluctuations generated by the air compressor 101 during operation. The outlet of the air storage tank 102 is connected to the inlet of the air pretreatment assembly 2, ensuring a stable supply of compressed air to the pretreatment assembly for further processing.

[0030] This design improves system stability, avoids pressure fluctuations caused by continuous compressor operation, and maintains a stable air supply.

[0032] The embodiment adopts a two-in-one standby mode to provide a compressed air source for the subsequent commonly used nitrogen generation system, and the combination of the air compressors 101 can be selected and switched. The advantage of this configuration is to improve the redundancy and reliability of the system.

The dryer 202 removes moisture in the air to avoid the influence of moisture on the purity of the nitrogen generated by the membrane separation host 3. The heater 204 is used to heat the air to ensure that the air temperature is suitable for the membrane separation process, thereby improving the membrane separation efficiency.

[0037] The pressurizer 401 is responsible for pressurizing the low-pressure nitrogen separated by the membrane separation host 3 to the required high pressure to meet the high-pressure nitrogen demand of different cabins and equipment of the ship. The air inlet of the pressurizer 401 is connected to the air outlet of the membrane separation host 3, and the air outlet delivers the pressurized nitrogen to the nitrogen storage tank 402 through a pipeline. The nitrogen storage tank 402 is used to store the pressurized nitrogen to provide stable high-pressure nitrogen supply for various equipment of the ship.

[0038] The arrangement of this pressurization assembly can effectively increase the pressure of the nitrogen supply to ensure the supply of high-pressure nitrogen required by the ship under different working conditions.

[0039] As an optional implementation, the gas supply module 5 comprises: a low-pressure gas supply pipeline 501, the gas inlet end of which is connected with the gas outlet end of the membrane separation host 3; and a high-pressure gas supply pipeline 502, the gas inlet end of which is connected with the gas outlet end of the nitrogen pressurization assembly 4.

[0040] The gas inlet end of the low-pressure gas supply pipeline 501 is connected with the gas outlet end of the membrane separation host 3, which is mainly responsible for delivering low-pressure nitrogen to low-pressure demand areas or equipment.

[0043] As an optional implementation, the nitrogen produced by the membrane separation host 3 enters the gas storage tank 7 after passing through the buffer gas tank 6, and unqualified nitrogen can be exhausted through the exhaust pipe 8 before entering the gas storage tank 7.

[0044] As an optional implementation, the air pretreatment assembly 2 and the membrane separation host 3 are integrated on a pry seat.

[0045] The air pretreatment assembly 2 and the membrane separation host 3 are integrated on a pry seat (i.e., a dedicated rack), forming an integrated module. This design can simplify the installation process, integrate multiple components on the same platform, help reduce space occupation, facilitate the spatial layout of the ship and system maintenance. The integrated design on the pry seat also helps improve the structural stability of the system, reduces connection problems between components, and improves the operational reliability of the system.

[0046] As an optional implementation, the system further comprises a switching control module for controlling the flow and pressure of each pipeline in the gas supply module 5.

[0047] The switching control module can automatically switch the working state of the low-pressure or high-pressure nitrogen gas supply pipeline according to different working conditions, ensuring that the nitrogen supply meets the different needs of each cabin of the ship. This function makes the system more flexible, allowing precise adjustment of gas flow and pressure according to actual needs, improving energy use efficiency, and ensuring efficient operation of the system.
