Integrated reliquefaction LPG recyclable pipeline system

Abstract

The invention relates to the technical field of ship fuel supply, in particular to an integrated reliquefaction LPG recyclable pipeline system which comprises a main supply module, a storage module, a supply main engine module, a control module and a filling module. The output end of the supply main engine module communicates with a main engine, and the input end of the supply main engine module communicates with the main supply module, the storage module and the filling module through liquid phase pipes. The main supply module communicates with the storage module through an inert gas pipe, and respectively communicates with the storage module and the filling module through a liquid phase pipe and an evaporation gas pipe. The control module is connected with the main supply module, the storage module and the filling module and controls the flow direction and on-off of media in the liquid phase pipe, the evaporation gas pipe and the inert gas pipe so as to control the storage amount and phase change of the media in the main supply module and the storage module. The integrated reliquefaction LPG recyclable pipeline system has the advantages that the main supply module and the storage module are arranged at the same time, when the fuel liquid level of the main supply module is low, the storage module is used for timely supplementing, and endurance is greatly improved. The equipped control module realizes automatic control.

Description

technical field [0001] The invention relates to the technical field of ship fuel supply, in particular to an integrated reliquefied LPG recirculating pipeline system. Background technique [0002] With the further requirements of the IMO (International Maritime Organization) pollution emission regulations for marine clean energy, various ships have begun to use LPG (liquefied petroleum gas) as the main engine power fuel during construction and refitting. The general solution is to use a separate LPG daily tank Fuel supply-based, see Figure 9 , the current LPG supply system has the following problems and shortcomings: [0003] 1. The volume of the independent daily tank is limited, and the battery life is limited. [0004] 2. If the independent daily tank encounters the problem of high temperature and cannot deal with the problem of rising evaporation rate, it needs to be discharged urgently, which wastes part of the fuel and pollutes the atmosphere. [0005] 3. There are ...

AI Technical Summary

Problems solved by technology

[0003] 1. The volume of the independent daily tank is limited, and the battery life is limited

[0004] 2. If the independent daily tank encounters the problem of high temperature and cannot deal with the increase of evaporation rate, it needs to be discharged urgently, which wastes part of the fuel and pollutes the atmosphere

[0005] 3. There are only simple gas phase and liquid phase ports, no dedicated filling station, and simple functions. When overpressure can only be discharged in an emergency, resulting in waste of fuel and pollution of the atmosphere
