[0002] The adsorption tower of an industrial oxygen generator consists of two adsorption towers filled with molecular sieves. These adsorption towers operate at room temperature. After compressed air is purified through filtration, water removal and drying, etc., it enters the adsorption tower. In the adsorption tower, nitrogen and the like in the air are adsorbed by the molecular sieve, while oxygen is enriched in the gas phase, flows out from the outlet and is stored in the oxygen buffer tank. When one tower finishes adsorption, the molecular sieve that has completed adsorption is quickly depressurized to desorb the adsorbed components. The two towers alternate in a cycle, and oxygen with a purity of ≥90% can be obtained. The automatic switching of the valves in the entire system is automatically controlled by a computer, realizing the process of continuous oxygen production.

[0003] At present, there are still some defects in the installation of the upper cover of the existing oxygen generator adsorption tower. Often, a large number of bolts are required for installation and connection.
