Problems solved by technology

Membrane oxygen production technology has little environmental pollution, but due to the fragile membrane, it is not mature enough in application
[0004] Pressure swing adsorption technology can work at room temperature and low pressure. The equipment used in this technology is simple and operates in a continuous cycle, which can be fully automated, but the rate of the prepared oxygen product is low.
Therefore, to overcome the low rate of PSA technology to meet the needs of development

Description

technical field [0001] The invention belongs to the field of oxygen production equipment, in particular to a pressure swing adsorption oxygen production radial flow adsorption tower. Background technique [0002] At present, oxygen production methods include air refrigeration separation technology, membrane oxygen production technology and pressure swing adsorption technology. Air cryogenic separation technology refers to the process of separating oxygen, nitrogen, helium and rare gases from air by applying the principle of cryogenic refrigeration. Generally, the air is first compressed and cooled to a very low temperature, or the air is liquefied by expansion, and then separated in the rectification tower. Air refrigeration separation technology is suitable for large-scale oxygen production, but the process is complicated and the cost is high. [0003] Membrane oxygen production technology uses the principle of osmosis, that is, molecules move through the membrane to the ...
