Abstract

The invention discloses a hydrogen liquefaction system with a hydrogen element detection function. An outlet of a gaseous hydrogen source communicates with an inlet of a heat exchanger through a hydrogen purifier. An outlet of the heat exchanger communicates with an inlet of an absorber. An outlet of the absorber communicates with an inlet of a first hydrogen ortho-para conversion reactor. An outlet of the first hydrogen ortho-para conversion reactor communicates with an inlet of a hydrogen cooling circulation system. An outlet of the hydrogen cooling circulation system communicates with an inlet of a second hydrogen ortho-para conversion reactor. An outlet of the second hydrogen ortho-para conversion reactor communicates with an inlet of a liquid hydrogen filling and delivery unit. The inlet of the heat exchanger, the outlet of the absorber, the outlet of the second hydrogen ortho-para conversion reactor and the liquid hydrogen filling and delivery unit are all connected with a hydrogen element detection and analysis module. The hydrogen liquefaction system with the hydrogen element detection function has the advantages that the liquid liquefaction efficiency is high, the investment cost is low, and the quality of liquid hydrogen is good.

Description

Technical field [0001] The invention relates to the technical field of hydrogen liquefaction, in particular to a hydrogen liquefaction system with a hydrogen component detection function. Background technique [0002] With the development of industry and the improvement of people's material living standards, the demand for energy is also increasing day by day. Because fossil energy such as coal and petroleum will inevitably pollute the environment when in use, coupled with its limited reserves, mankind is faced with the arduous challenge of developing efficient and clean secondary energy, so it is urgent to find renewable green energy. As an ideal energy carrier that can be obtained from multiple sources, hydrogen is one of the important bridges for the transition from fossil energy to renewable energy and will provide a new and important form of terminal energy utilization. Hydrogen energy utilization needs to solve a series of problems such as production, storage and transport...
