Vacuum insulation type ultra-low temperature medium land transportation device

Abstract

The invention relates to a vacuum insulation type ultra-low temperature medium land transportation device. The rear end of the rotating inner tube is connected to the liquid phase interface through the liquid phase rotary joint, and the gas phase interface is fixedly connected to the column, and the gas phase interface is connected to the gas phase channel in the rotating inner tube. The gas phase and liquid phase outlets are arranged under the front end of the rotating inner tube. The gas phase outlet is connected to the gas phase valve through the gas phase rotary joint, the gas phase rotary tube, the gas phase turbine worm device, the gas phase vacuum outer tube, and the gas phase interface center of gravity adjustment tube; the liquid phase outlet The liquid phase valve is connected through a liquid phase rotary joint, a liquid phase turbine scroll device, a liquid phase vacuum outer tube, two liquid phase rotary joints, and a liquid phase interface gravity center adjustment tube. The invention solves the phenomenon of cold loss caused by the frosting and icing of the original loading and unloading arm, can reduce the BOG generated by gasification, and reduce the pressure of the system cycle treatment; overcome the leakage caused by the low temperature deformation of the rotating parts; prevent the interface from freezing, improve the connection speed and Loading and unloading time, without nitrogen protection, saving operating costs.

Description

technical field [0001] The invention relates to a land transportation device for ultra-low temperature medium, in particular to a land loading, unloading, filling and transportation device for ultra-low temperature media, such as liquid oxygen, liquid nitrogen, LNG and other ultra-low temperature liquids or gases. Background technique [0002] The ultra-low temperature medium land conveying device is used in the loading and unloading process of ultra-low temperature medium, such as liquid oxygen, liquid nitrogen, LNG and other ultra-low temperature gases or liquids. 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 farm, and finish the installation and commissioning work. When the tank car enters the station for loading, let the tank car stop within the design enveloping range of the device, then pull the handle on the flange pipe of the liquid-phase connecting car...
