A high purity helium purifier for industrial applications has been developed.A high purity helium purifier for in-dustrial application has been developed to purify helium by gas separation at low temperature adsorption,the helium gas with inlet pressure of 2～22 MPa,flow rate of more than 300 Nm3/h and purity of more than 30％was purified to 99.999％high purity helium at one time.Research and development design mainly from the process of industrial purifier simulation design,process design,instrument control design to achieve the continuous operation of industrial systems.The adsorber in the industrial purifier works alternately in low temperature purification and rewarming activation,which needs to go through alternating working conditions of variable temperature,so the fatigue analysis design is added to the design of the vessel,the safety of the container is guaranteed theoretically.The design of industrial high purity helium gas purifier adopts two or more groups,single group multi-tower switch,automatic control design,perfect alarm interlock function,ensuring the safe and continuous operation of the equipment and realizing unattended operation.
