Abstract

The invention provides a high-purity hydrogen preparation device. The high-purity hydrogen preparation device comprises a hydrogen production device, a hydrogen purification device and a hydrogen collection device. The hydrogen production device further comprises a byproduct collection device. The hydrogen purification device comprises three membrane separators, two gas flow meters, a purificationtreatment device, a nitrogen collection device, a heat exchanger, a pressurization device and a pressure reduction device. The purification treatment device comprises a purification treatment devicemain body, a box body bottom layer made of a hydrogen storage metal material, a piston and a piston locking device. The hydrogen collection device comprises a collection device and a storage device. The membrane separator and the hydrogen storage metal material are adopted to prepare the high-purity hydrogen, so that the energy consumption for preparing the high-purity hydrogen is effectively reduced. And the byproduct in the process of preparing high-purity hydrogen also has very high commercial and industrial values, and is environment-friendly and safe.

Description

technical field [0001] The invention relates to a hydrogen preparation system, in particular to a high-purity hydrogen preparation device. Background technique [0002] The largest amount of hydrogen is used as an important petrochemical raw material for the production of synthetic ammonia, methanol and hydrogenation reactions in petroleum refining processes. It is also widely used in electronic industry, metallurgical industry, food industry, float glass, fine organic synthesis, aerospace industry and other fields. Petrochemical industry is one of the basic raw materials of modern oil refining industry and chemical industry. Hydrogen is widely used in chemical industry in various forms. Most of the hydrogen used in the synthesis of ammonia and methanol is produced by steam reforming or partial oxidation of natural gas, naphtha or heavy oil. The amount of hydrogen used in the petroleum refining industry is second only to synthetic ammonia. In fuel cells, high-purity hydro...
