Argon purifying and recovering device is an argon gas (recovery pressure slightly higher than atmospheric pressure) with various impurities that was directly discharged to the atmosphere through primary dust filtering and back-blowing recovery device, precision secondary filtration, pressurization by compressor, dewatering by freeze-dryer, deoxidizing by deaerator, deep absorption and removal of trace oxygen, water and gas impurities in argon by drying equipment, fully automatic argonHigh purity argon recovery and purifying equipment of gas recovery and purification system obtains extremely high purity argon, which is finally sent to the working point through precise precise precise metal filter.
