Description

technical field

[0001] The invention relates to the technical field of hydrogen purification, in particular to a hydrogen purifier. Background technique

[0002] As a very important industrial raw material and a clean energy, hydrogen is widely used in petrochemical, electric power, metallurgy and other industries. With the rapid development of science and technology, all walks of life have put forward more and more requirements for the purity of hydrogen high demands.

[0003] Hydrogen has the advantages of high thermal conductivity, strong fluidity, low density, and no combustion support. It is currently the main cooling medium used in large turbogenerators, and the purity of hydrogen in generators directly affects the safety and economy of unit operation. Hydrogen is an extremely explosive dangerous product. When the hydrogen content in the air is between 4.1% and 74.2%, the mixed gas is an explosive gas. The purity of hydrogen should be guaranteed to be above 95% during...
