Description

Metal hose box of unloading platform

Technical Field

The utility model relates to the technical field of liquefied natural gas conveying, in particular to a metal hose box of an unloading platform.

Background

Liquefied natural gas is conveyed to a station by an LNG tank car and is connected with the tank car through an unloading platform metal hose, so that a tank car body is communicated with an unloading platform supercharger and a tank to be filled with liquid, the tank car body is used for pressurization and liquid unloading operation of the tank car body, low-temperature LNG liquid enters a process pipeline through the metal hose in the liquid unloading process of the tank car, after the liquid unloading process is finished, although evacuation treatment is carried out, part of the low-temperature LNG liquid still possibly remains in the metal hose, one end of the metal hose is connected with the process pipeline at the moment, the other end of the metal hose is directly exposed outside, at the moment, if an operator accidentally touches the metal hose, the low-temperature LNG liquid in the remaining pipe can be sprayed out, the operator is frostbitten by the low-temperature liquid, and the exposed flange opening is easy to enter water, stick dust, climb into small animals and the like, so that the risk of blocking the process pipeline is increased.

At present, related risks are reduced by means of increasing flange plugs in the market, plastic plugs are directly added, and the plastic plugs are not firm to install and easy to fall off. And the unloading process is easy to forget to remove before unloading, thereby increasing the unloading risk. When the metal blind plate is installed, the operation is complex, the liquid seal of the metal hose is easy to cause, and the risk of equipment damage is increased.
