AI Technical Summary
During the production or cleaning of oxygen cylinders, conventional drying methods lead to greater energy consumption, and due to the small opening of the oxygen cylinder, the drying internal moisture cannot be effectively emptied.
A medical oxygen cylinder inner wall drying device is designed to discharge dry hot gas through the gas pipe and extract moisture from the top. The heated circulating gas is absorbed by an adsorption drying box to achieve sufficient drying of the inside of the gas cylinder.
The device reduces energy consumption by recycling hot air, and through the design of adsorbing drying box, it can effectively discharge moisture inside the air bottle and achieve a more efficient drying effect.
