Embodiment Construction

[0023] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0024] Such as figure 1 As shown, the liquid hydrogen vacuum delivery pipe includes a flexible transfer pipe 1 , and the wall of the flexible transfer pipe 1 is provided with a vacuum interlayer 2 .

[0025] The flexible adapter tube is made of poor conductor material, such as rubber, plastic, etc.

[0026] The flexible transition pipe 1 is a corrugated pipe, which can be twisted and is convenient to be connected with the storage tank and the container.

[0027] Several support blocks 5 are evenly distributed and fixed in the vacuum interlayer 2, and the support blocks 5 are used to support the inner cavity of th...

Abstract

The invention discloses a liquid hydrogen vacuum conveying pipe, and relates to the technical field of liquid hydrogen conveying tools. The conveying pipe comprises a flexible adapter pipe, and a vacuum interlayer is arranged on the pipe wall of the flexible adapter pipe. The problems that in the prior art, an existing hard transfer pipe is limited by the structure of the hard transfer pipe, a storage and transportation tank and a containing container are inconvenient to connect, operation wastes time and labor, and due to the fact that the low-temperature condition of liquid hydrogen cannot be guaranteed through the transfer pipe, the phenomenon that the liquid hydrogen is gasified in the conveying process is easily caused are solved.

Description

technical field [0001] The invention relates to the technical field of liquid hydrogen transport equipment, in particular to a liquid hydrogen vacuum transport tube. Background technique [0002] Hydrogen energy is a secondary energy source. It has high combustion calorific value and its product is water. It is the cleanest energy source in the world. Abundant resources and sustainable development, hydrogen production, storage, transportation, and application technologies will also become the focus of attention in this era. Hydrogen energy transportation mainly includes compressed hydrogen transportation, liquid hydrogen transportation, and the use of hydrogen storage media. Transportation, pipeline transportation and transportation of manufacturing raw materials, in which liquid hydrogen can only exist in the form of liquid at minus 253°C, and for large-scale liquid hydrogen transportation, it is transported by trailers through storage tanks. [0003] A patent of CN2019221...
