Description

Technical Field

[0001] This utility model relates to the field of oxygen production technology, specifically to an oxygen production system. Background Technology

[0002] Oxygen generators utilize the selective adsorption properties of oxygen-producing molecular sieves. They employ a cycle of pressurized adsorption and depressurized desorption, alternatingly introducing compressed air into the adsorption tower to achieve oxygen and nitrogen separation from the air. This results in the continuous and stable production of high-purity oxygen. Oxygen generators offer advantages such as high reliability, energy efficiency, convenient operation and maintenance, and low investment. They are widely used in various fields, including oxygen-enriched combustion, wastewater sterilization, medical and health care, and aquaculture.

[0020] This utility model provides an oxygen generation system that can solve the problem of system paralysis and low reliability in related technologies when a fault occurs.

[0021] See Figure 1 , Figure 2 and Figure 3As shown in the figure, an oxygen production system provided by this utility model includes an air compressor 1, a vacuum pump 2, a blower 3, a first adsorption tower 4, a second adsorption tower 5, and a nitrogen purging device 6.

A valve 12 812 is installed at one end of the sixteenth pipeline 716 near the first pipeline 701, and a valve 13 813 is installed at the other end of the sixteenth pipeline 716 near the sixth pipeline 706.

In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0038] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
