Movable LNG marine fuel tank box

Abstract

The invention discloses a mobile LNG marine fuel tank box, which includes a container standard frame and a tank body. One end of the tank body is equipped with a pipeline system, the pipeline system comprises an exhaust port quick-release coupling, a safe discharge system, a gas port, a self-pressurization device, and a feed liquid port, the exhaust port quick-release coupling, the gas port, and the feed liquid port are dismountable flange interfaces, the feed liquid port and a LNG gas supply system are connected by a Roman Seliger liquid adding gun, the tank body is internally provided with a temperature measuring device, which is in connection with a PLC cabinet. The mobile LNG marine fuel tank box provided by the invention has the characteristics of convenient and fast ''filling'', convenient inspection and maintenance, and high ship space utilization rate, changes a fixed storage tank to a mobile tank box, and changes aquatic filling to land filling.

Description

technical field [0001] The invention relates to a movable LNG marine fuel tank. Background technique [0002] There are two types of LNG-powered marine fuel storage tanks, one is fixed and the other is mobile. After the fuel in the fixed fuel tank is used up, it needs to be refilled with LNG filling pontoon or LNG low-temperature tanker. Note, however, the huge investment in LNG bunkering pontoons makes it difficult to deploy a large number of points along the inland river. In fact, the problem of LNG bunkering is not only a problem that needs to be overcome in the promotion of LNG ships in my country, but also a problem that needs to be solved urgently in the process of promoting LNG in the world. , At present, Finland adopts "LNG storage and distribution station", which integrates storage, distribution and logistics, and carries out ship-to-ship refueling. In terms of system, it does not apply to our country. On the other hand, inland rivers such as the Yangtze River in my ...

Problems solved by technology

[0004] 1. The filling method is single. Due to the restriction of national policies, this kind of fixed LNG marine fuel storage tank can only be filled with LNG water filling pontoons at present. Due to the reasons mentioned above, there are few spots for LNG water filling pontoons. This has seriously affected the use of LNG fuel-powered ships

2. The filling time is long and there are potential safety hazards. It takes more than an hour to fill a 5 cubic meter fuel tank, and because the filling pipe needs to be assembled and disassembled, LNG leakage is prone to occur. It is no exaggeration to say that in the fuel tank Among the various links of use, LNG filling is the most dangerous
