Automatic-controlled movable LNG fuel tank gas supply system for vessel

Abstract

The invention discloses an automatic-controlled movable LNG fuel tank gas supply system for a vessel. The gas supply system comprises an LNG fuel tank, a gasification unit, a river water heating circulation system, a ventilation spreading device, an LNG fuel control monitoring system, a valve piece, an LNG pipe system, a dual-fuel main engine and a heat exchanger, wherein the LNG fuel tank comprises an LNG storing tank and a frame; the LNG fuel storing tank is fixed in the frame; the gasification unit comprises a water bath vaporizer and a buffer tank; and the LNG storing tank is connected with the water bath vaporizer through quick connectors. According to the automatic-controlled movable LNG fuel tank gas supply system disclosed by the invention, on-site charging is not needed, so that the number of times for on-site charging of the vessel is reduced, and risk of accidental leakage is greatly reduced; and besides, performance parameters of each component in the LNG fuel system are dynamically monitored by the LNG fuel control system, and are displayed on a man-machine interface in a driving cab and a man-machine interface in an LNG fuel control tank in a central control room.

Description

technical field [0001] The invention belongs to the field of marine control equipment, in particular to a marine automatic control movable LNG fuel tank gas supply system, which is a marine automatic control movable LNG fuel tank gas supply system integrating LNG storage, gasification and control. Background technique [0002] There are more than 1 million fishing boats of various types in my country, accounting for a quarter of the total number of ships in the world and 90% of the total number of ships in my country. However, there are more than 500,000 motorized fishing boats in my country, and the annual fuel consumption is more than 8 million tons. , The exhaust gas discharged seriously pollutes the atmosphere and rivers, lakes and seas. Energy saving and environmental protection have become the themes leading the development of global economy and technology. At present, a new type of alternative energy, liquefied natural gas (LNG), has entered the fishing vessel industry...

AI Technical Summary

Problems solved by technology

[0003] At present, since the fuel tank is fixed on the ship, when an accident occurs to the fuel tank or the heat insulation performance is lost, the fuel tank cannot be repaired or the maintenance time is very long on the ship, and the ship will stop running due to the loss of power source, causing huge losses to the ship owner
