Problems solved by technology

Because LNG is low-temperature liquefied natural gas, the temperature is about -162°C, the longer the pipeline, the larger the heating area, it is easy to gasify, and the pipeline is over-pressurized, resulting in economic losses or even explosion accidents. Therefore, the LNG pipeline should be as short as possible and strictly prepared. Cooling measures

Embodiment Construction

[0017] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, a mobile LNG filling trolley according to the present invention is provided with a track 1 for the quay bridge 11. The track 1 is provided with a mobile trolley 2 that can move along the track 1, and the mobile trolley 2 is provided with an LNG The filling device; the filling device includes an LNG storage device 21, a filling pump 22, a meter 23 and a loading and unloading arm 24 connected in sequence through a pipeline 25; the mobile trolley 2 can be refitted from a flatbed vehicle, and the The specifications are determined according to the specifications and quantity of the filling device. The mobile trolley 2 can be driven by its own power equipment, or can be moved along the track 1 by using the traction facilities on the wharf; when loading and unloading LNG, the quay bridge 11 is moved to one e...

Abstract

The invention relates to the technical field of port loading-unloading equipment, in particular to a mobile LNG filling trolley. A moving trolley capable of moving along a rail used for quay crane touse is arranged on the rail, and a LNG filling device is arranged on the moving trolley and comprises a LNG storage device, a filling pump, a metering device and a loading-unloading arm sequentially connected through a pipeline. The mobile LNG filling trolley is reasonable in structure, occupied area of the filling device is reduced to greatest extent, and investment is saved; the filling device can be moved wholly, and quay crane operation is unaffected, so that a same quay has two functions of loading and unloading containers and filling at the same time; for ships different in type and tonnage, ship interface positions are different, and the filling device can be moved integrally, so that the problem of docking with the ships is solved well, and docking is more flexible and convenient;pipeline investment is saved, and yield of BOG steam is reduced.

Description

technical field [0001] The invention relates to the technical field of port loading and unloading equipment, in particular to a mobile LNG filling trolley. Background technique [0002] Under the policy background of "Building a Beautiful China" and "Green Development", the application of natural gas has developed rapidly. Especially in recent years, the Ministry of Communications has vigorously promoted the ship-to-gas project, changing the original oil-fired ships to LNG-powered ships, and LNG as fuel More environmentally friendly than fuel. At present, a small number of ships in China have been converted to LNG fuel. There is no formally approved bunkering terminal on the Yangtze River, and the few built are only trial operations in the form of pilot demonstrations. LNG tank container transportation has only been carried out for a few days. Pilot ship transport. [0003] The conventional LNG filling terminal process is: LNG storage tank→pump→metering equipment→loading a...
