Low-temperature hydrogen purifier is a kind of equipment used to purify hydrogen, which uses low-temperature adsorption technology to remove the impurities in hydrogen, so as to get high purity hydrogen.
It is used in the fields of electronics, chemical industry, laboratory research, fuel cell and gas analysis.

Hydrogen purification device (hydrogen refining equipment) Hydrogen purifier Hydrogen purification equipment series takes hydrogen in cylinder, hydrogen from ammonia decomposition, hydrogen recovered from the tail gas of chemical plant as raw material, and goes through the precious metal palladium touching coal catalytic deoxygenization, condensation, adsorption of the second level of drying, filtration, and removes the  mpurity of oxygen, water,and dust in the hydrogen, and obtains the high purity of hydrogen gas.   

Working Principle

The air purification system utilizes the principle of variable pressure and temperature adsorption, and adopts the heating adsorption method to dry, dehumidify and de-CO2 the compressed air. the structure is of double-tower type, when one adsorbs, the other regenerates. The working cycle consists of an airflow rising adsorption of CO2, drying process and an airflow falling regeneration process. Regeneration, the introduction of a part (about 6% ~ 10%) has been dried compressed air, through the orifice plate throttling expansion and pressure reduction, and then into the heater heating, heated high-temperature gas and then into the tower will be adsorbed in the desiccant water and CO2 desorption blowing out. When the regeneration is switched to drying, the water and CO2 in the compressed air is adsorbed on the desiccant again, so the cycle of work to achieve the purpose of CO2 removal and drying.
