Multifunctional LNG power generation boat

Abstract

The invention relates to a multifunctional LNG power generation boat. A power generation unit comprises gas power generation unit bodies and dual-fuel power generation unit bodies. The gas power generation unit body A is connected with a gas supply pipeline of the gas power generation unit body B. The dual-fuel power generation unit body A is connected with a gas supply pipeline of the duel-fuel power generation unit body B. A distribution board is connected with the gas power generation unit body A, the gas power generation unit body B, the dual-fuel power generation unit body A and the duel-fuel power generation unit body B. An external power supply device, variable-frequency and variable-voltage equipment A, variable-frequency and variable-voltage equipment B, variable-frequency and variable-voltage equipment C and variable-frequency and variable-voltage equipment D are connected with the distribution board. A cable reel is connected with the external power supply device. In the external power supply process, power generation is conducted by combusting LNG, emission of nitric oxide and sulfur oxide is greatly reduced, and environment pollution caused by coastal / inland vessels is effectively relieved; the combustion power generation process is stable, and continuous, stable and sufficient power supply is guaranteed; and LNG cold energy has an air regulation function in the process, and the working environment of an engine room is effectively improved.

Description

technical field [0001] The invention relates to the technical field of LNG ships, in particular to a multifunctional LNG power generation ship. Background technique [0002] my country is an important shipping country in the world, and its coastal transportation demand and port foreign trade throughput rank first in the world. With the continuous development of maritime trade, the number of bulk carriers, container ships, oil tankers and other transport ships calling at Chinese ports is increasing, resulting in an increasing amount of air pollutant emissions from port ships. Due to the low standard of shipping fuel in my country's ports, ships mainly use heavy oil or low-quality diesel, and about 70% of the ocean-going ship exhaust is discharged in the sea within 400 kilometers from the coastline, which has seriously affected the air quality of coastal cities and some inland cities. [0003] Pollution from ships and shipping has become the third largest source of air pollut...

Problems solved by technology

[0004] At present, there is a power demand for ships calling at ports at home and abroad. Generally, domestic ships using auxiliary engines to generate electricity to meet their own power needs, but the pollution is serious; developed countries in foreign countries use shore power or switch to low-sulfur oil, but port ships use Shore power needs to be equipped with considerable power facilities, the economy is relatively unobvious, and there are difficulties in the production and supply of low-sulfur oil in my country

[0005] The existing power generation ship technology usually converts wind energy, ocean energy, etc. into electric energy. The power generation capacity is small, and there are many influencing factors, and it cannot guarantee continuous and effective supply in a short period of time; Single, causing a certain waste of ship resources during the power demand gap period
