The argon gas recovery device signed by DEAR and a Shanghai enterprise is to recycle and reuse argon gas. The use of this series of devices is a powerful measure to reduce production costs, save energy and improve economic benefits. From the perspective of improving the low-carbon environment, argon recovery is also a significant work in the future development.
The argon purification and recovery device is the argon gas (recovery pressure slightly higher than atmospheric pressure) containing various impurities that was directly discharged into the atmosphere through the primary filtration dust and backflush recovery device, precision secondary filtration, pressurized by the compressor, and frozen dryer dehydration, deoxidizer, oxygen, deep adsorption of the drying equipment to remove trace oxygen, water and gas impurities in the argon, fully automatic argon recovery and purification system, high purity argon recovery and purification equipment to obtain extremely high purity argon , and finally sent to the working point through the precious metal precision filter.

KDAr-1500 Product advantages |
|
The device adopts molecular sieve purification, back-filled liquid argon to supplement the cooling capacity, and at the same time, a deep-cooled full distillation argon purification process. This process is safe and reliable, and it is also economically reasonable. The main reasons are: 1. Good security The entire device has low operating pressure, simple technology, high equipment safety, long switching cycle of the molecular sieve system, increased service life of the switching valve, and reduced hidden safety hazards. 2. High reliability. 3. Easy operation and maintenance, simple process. |
