Embodiment Construction

[0019] 1. Filling of LNG vacuum double-wall storage tank

[0020] Such as figure 1 , figure 2 , image 3 As shown, the LNG vacuum double-wall storage tank 7 is arranged on the lower layer of the double-layer container frame 28. When filling, the filling valve 2 and the return valve 3 are opened at the same time, and then LNG liquid is filled to the filling interface 1, thereby realizing Fill the LNG liquid in the LNG vacuum double-wall storage tank and return the excess evaporated gas in the tank to ensure the air pressure balance in the tank. After the filling and filling of the storage tank is completed, close the filling valve 2 and the return valve 3.

[0021] 2. LNG fuel generator fuel supply

[0022] Firstly open the main valve 11, then open the inlet valve 12 and the outlet valve 4 of the self-pressurized evaporator, LNG flows through the self-pressurized evaporator 8 by gravity, converts heat from liquid LNG into gaseous natural gas, and returns to the LNG vacuum d...

Abstract

The invention discloses an LNG fuel and solar energy combined movable shore-based power supply system which comprises an LNG fuel storage tank, an LNG fuel generator, a power distribution device, a storage battery, a power supply interface and a solar base plate, wherein the LNG fuel generator is used for realizing the LNG fuel power generation; the solar base plate utilizes the solar energy to generate power; the electric energy generated by the solar base plate is merged into the storage battery and is used for supplying power. The improvement is that evaporation and heating devices required by the LNG fuel power generation are arranged between the LNG fuel storage tank and the LNG fuel generator and the heat energy required by the evaporation and heating devices is jointly supplied by the solar energy and the electric energy for the LNG fuel power generation. According to the invention, the electric power storage is completed and the heat for the heat transfer required by the running of the system is supplied; the electric power output load of the LNG fuel generator is greatly relieved, so that the LNG fuel consumption is reduced; the beneficial effect of energy conservation and emission reduction is realized.

Description

technical field [0001] The present invention relates to a shore-based power supply system, and more specifically, relates to a new type of mobile shore-based power supply system that utilizes two clean energy sources of LNG (liquefied-natural-gas) and solar energy for combined power generation. Background technique [0002] With the implementation of the "Pearl River Delta, Yangtze River Delta, and Bohai Rim (Beijing-Tianjin-Hebei) Waters Vessel Emission Control Area Implementation Plan", the Yangtze River Delta, Pearl River Delta, and Bohai Rim waters have been established as ship emission control areas. Conventional ships without engine modifications or exhaust gas treatment devices have entered the above-mentioned areas, and the conversion of low-sulfur oil has become their main means. The high price of low-sulfur oil and the frequent conversion of low-sulfur oil will damage the main engine, which will undoubtedly increase the cost of shipping companies. [0003] How to ...
