Induction heating solid hydrogen storage and desorption system and hydrogen storage and desorption method

Abstract

The invention discloses an induction heating solid hydrogen storage and desorption system and a hydrogen storage and desorption method. A solid hydrogen storage tank is made of a magnetic material, the solid hydrogen storage tank body serves as a heating body, a magnetic field generated by an electromagnetic coil acts on a storage tank body, so that the storage tank body generates eddy current to generate heat and heat a hydrogen storage material in the solid hydrogen storage tank, and therefore the heating rate of the hydrogen storage material is increased, when hydrogen storage is conducted, hydrogen enters the solid hydrogen storage tank through an air inflation branch, when the hydrogen is supplied to the outside, a cooling device is arranged at the outlet position of the hydrogen storage tank, a temperature sensor at the rear end of the cooling device is used for monitoring the temperature in a main pipeline in real time, and a filtering device is used for filtering out fine hydrogen storage material dust in gas, so that cooling and dedusting are conducted on the hydrogen. According to the induction heating solid hydrogen storage and desorption system and the hydrogen storage and desorption method, the system not only can blow gas to pipelines and parts so as to remove the hydrogen and facilitate subsequent maintenance, but also can recycle the blown and removed hydrogen and inert gas, so that the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogenation, in particular to an induction heating solid state hydrogen storage and discharge system and a hydrogen storage and discharge method. Background technique [0002] The hydrogen storage and dehydrogenation system has relatively high requirements for the safety of its surrounding environment. During use, the pressure of the pipeline will be adjusted through a safety valve, but in most cases the hydrogen is directly discharged into the surrounding environment. During the process, it is necessary to regularly overhaul the pipelines and components to avoid problems such as air leakage and component failures in the subsequent use process. However, because hydrogen is flammable and explosive, during the maintenance process, the residual hydrogen in the pipelines and various components It is very easy to cause safety accidents in the follow-up maintenance process. [0003] Moreover, the existing so...

[0002] The hydrogen storage and dehydrogenation system has relatively high requirements for the safety of its surrounding environment. During use, the pressure of the pipeline will be adjusted through a safety valve, but in most cases the hydrogen is directly discharged into the surrounding environment. During the process, it is necessary to regularly overhaul the pipelines and components to avoid problems such as air leakage and component failures in the subsequent use process. However, because hydrogen is flammable and explosive, during the maintenance process, the residual hydrogen in the pipelines and various components It is very easy to cause safety accidents in the follow-up maintenance process

[0003] Moreover, the existing solid-state hydrogen storage systems (lanthanum-nickel series, titanium series, zirconium series, magnesium series and their derivative alloys) use electric heating to heat the heat exchange medium, and then heat the heat exchange medium to heat the magnesium-based hydride heating method, which is inefficient and Heat is wasted during heating

At the same time, in the heating process, the heating method of the heat exchange medium heating the magnesium-based hydride has the problems of uneven heating and slow heating rate.
