The argon purification and recovery device belongs to the argon air separation plant, which is to remove the trace oxygen, water and gas trace impurity from the argon gas,which is intented to be directly discharged into the atmosphere (the recovery pressure is slightly higher than the atmospheric pressure) through the primary filter dust and back blowing recovery device, precision secondary filtration, pressurization by the compressor, dehydration by the freeze dryer, deaerator deaeration, deep adsorption by the drying equipment. High purity argon is obtained from the high purity argon recovery and purification equipment of the automatic argon recovery and purification system, and finally sent to the working place for use through the precious metal precision filter. Argon air separation plant can be used to reduce production costs, save energy and improve economic efficiency.
