Metal hydride hydrogen storage container convenient to disassemble and assemble and capable of achieving effective heat exchange

Abstract

The invention discloses a metal hydride hydrogen storage container convenient to disassemble and assemble and capable of achieving effective heat exchange and relates to the technical field of hydrogen storage containers, in particular to a metal hydride hydrogen storage container convenient to disassemble and assemble and capable of achieving effective heat exchange. The container comprises a hydrogen storage alloy tank, a sleeve, flanges and hydrogen valves; the hydrogen storage alloy tank is installed in the sleeve and hermetically connected with the flanges through rubber spacers and flange bolt nuts; the centers of the flanges are provided with the hydrogen valves; hydrogen storage alloy powder is placed in the hydrogen storage alloy tank. According to the technical scheme, the problems are solved that in the prior art, in the hydrogen absorption process of hydrogen storage alloy, due to lattice expansion, the stress is generated to the inner wall of the container, so that the container deforms, and accordingly the service life of the container is influenced; the long-term circulation stability of the hydrogen storage alloy is poor, and the container needs to be frequently replaced; the thermal conductivity of the hydrogen storage alloy is poor, and a hydrogen storage device needs to perform heat transfer to the exterior.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage containers, in particular to a metal hydride hydrogen storage container that is easy to assemble and disassemble and capable of effective heat exchange. Background technique [0002] With the expansion of the global population and the rapid development of the economy, the energy crisis has become increasingly serious. The energy industry is an important benchmark to measure a country's economic strength and plays a very important role in national life. At present, my country's energy distribution and supply are unbalanced, the energy structure and layout are unreasonable, and the overall energy utilization rate is low. The primary energy consumption such as coal and fossils is the main consumption, and its large-scale combustion causes serious environmental pollution. With the continuous advancement of economic development and industrialization, the consumption of fossil energy has maint...

AI Technical Summary

Problems solved by technology

[0006] According to the hydrogen storage alloy proposed in the above prior art, during the hydrogen absorption process, the lattice expansion produces stress on the inner wall of the container, causing deformation of the container and affecting the service life of the container; the hydrogen storage alloy has poor long-term cycle stability and needs to be replaced frequently; the hydrogen storage alloy Due to poor thermal conductivity, the hydrogen storage device needs to transfer heat to the outside world and other technical problems, and a metal hydride hydrogen storage container that is easy to disassemble and has effective heat exchange is provided
