A hydrogen adsorber regeneration system and method thereof

Abstract

The present invention provides a hydrogen adsorber regeneration system and a method thereof, wherein the regeneration system comprises: a first gas supply unit for supplying hydrogen to be treated; an adsorption unit, connected with the first gas supply unit, comprising at least two switchable gas supply units When the first adsorber and the second adsorber are used, when the first adsorber performs adsorption, the second adsorber is regenerated; the regeneration gas supply unit is connected with the adsorption unit, and is used for supplying regeneration gas to the second adsorber, so as to The impurity gas generated during the regeneration of the second adsorber is discharged by the regeneration gas; the high-purity hydrogen supply unit is connected to the adsorption unit, and is used for supplying high-purity hydrogen with a preset temperature range to the second adsorber, so as to use the high-purity hydrogen to The regeneration gas in the second adsorber is discharged; the discharge unit is connected with the adsorption unit, and is used to discharge at least the impurity gas and the regeneration gas in the second adsorber. The hydrogen adsorber regeneration system provided by the present application can improve the regeneration depth of the hydrogen adsorber.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of hydrogen liquefaction, and in particular, to a hydrogen adsorber regeneration system and a method thereof. Background technique [0002] The utilization of hydrogen energy can solve the problems of sustainability, pollution emissions and energy security. In recent years, hydrogen energy has been widely used in the fields of national defense, aerospace, scientific engineering research, low temperature superconductivity, electronic chips, energy chemical industry, metallurgy and energy transportation. However, due to the storage and transportation of hydrogen energy, the commercial application cost of hydrogen energy remains high. We know that liquefied hydrogen (LH 2 ) has an energy density of almost 4.5 times that of compressed hydrogen at 200 bar, and if large quantities of hydrogen energy are transported from remote areas to urban hydrogen refueling stations, the storage and tran...
