Molecular sieves selectively adsorb oxygen and nitrogen components in the air to separate the air to obtain oxygen. When compressed air passes through the adsorption layer of the molecular sieve adsorption tower, nitrogen is preferentially adsorbed, and oxygen remains in the gas phase to become oxygen. When the nitrogen adsorbed on the molecular sieve reaches saturation, the nitrogen molecules adsorbed on the surface of the molecular sieve are removed by reducing pressure or vacuuming to restore the adsorption capacity of the molecular sieve. In order to continuously supply oxygen, the device is usually provided with two or more adsorption towers.
The intelligent manufacturing technology pioneered by Kaifeng DEAR air separation Co., Ltd. adds intelligent technologies such as laser and vision to key process and quality nodes, establishes Dier's unique process database, assists AI algorithm to optimize production, and carries out intelligent automatic control through MES bus, so as to achieve the goals of automation, informatization and intelligence of production, transparency and visualization of production line, and traceability of product manufacturing process. The intelligent production workshop has applied for the national "first set of air separation industry". Leading the development of industry 4.0.
