Abstract

The invention relates to a vacuum insulation type ultra-low temperature medium marine conveying device. The gas phase port and the liquid phase port of the rear vacuum box are respectively connected to the gas phase interface and the liquid phase interface through the gas phase rotary joint and the liquid phase rotary joint. The gas phase flow channel is formed by connecting the gas phase rotary joint with the vacuum gas phase inner tube, and the liquid phase flow channel is formed by connecting the liquid phase rotary joint with the vacuum liquid phase inner tube; One end of the tube and the liquid phase outer tube, and the other end of the gas phase outer tube and the liquid phase outer tube are respectively connected to the gas phase valve and the liquid phase valve through the gas phase rotary joint and the liquid phase rotary joint. The invention solves the phenomenon of cold loss caused by the frosting and icing of the original loading and unloading arm; it can reduce the BOG produced by gasification, reduce the pressure of the system circulation process, overcome the leakage caused by the low temperature deformation of the rotating parts, prevent the interface from freezing, and improve the connection efficiency. Speed ​​and loading and unloading time, no need for nitrogen protection, saving operating costs.

Description

technical field [0001] The invention relates to an ultra-low temperature medium marine conveying device, in particular to a loading and unloading ship for ultra-low temperature medium, such as liquid oxygen, liquid nitrogen, LNG and other ultra-low temperature liquid or gas, or a filling and conveying device for marine LNG. Background technique [0002] When the ultra-low temperature medium marine conveying device is used, first install the column on the prefabricated foundation, respectively connect the gas phase and liquid phase interface flanges to the pipe network from the tank area, and complete the installation and commissioning work. When the tanker enters the station for loading, unloading or refilling, let the tanker berth on the wharf and moor the cable within the enveloping range designed by this device, then start the electro-hydraulic system, operate the hydraulic system with the remote control handle, and drive the oil cylinder to drive the liquid phase The pip...
