Description

technical field [0001] The invention belongs to the technical field of oxygen production in an underwater sealed space, and more specifically relates to a perovskite-type oxide-based chemical chain cycle oxygen production system. Background technique [0002] Modern underwater power units work underwater for a long time. To complete multiple tasks such as lurking, detection, reconnaissance, attack, and defense, it is necessary to carry multiple crew members. Since the underwater power unit does not surface for several months in a row, its acquisition of oxygen resources is particularly important. At the same time, the emission of engine combustion exhaust in the underwater power plant is a relatively big problem. It has high heat and needs to be cooled before being discharged. If it is directly discharged outside the cabin, the unburned oxygen and carbon dioxide will form a wake, which greatly reduces concealment. sex. Therefore, aiming at the working environment of the un...

Problems solved by technology

The per (super) oxide used in the production of oxygen by per (super) oxide contains CO 2 The water vapor in contact with the air absorbs the CO in the air 2 produce O 2 , but the per (super) oxide regeneration agent absorbs CO containing water vapor 2 After that, expansion and gelatinization will occur, and the reaction efficiency will be significantly reduced.

Therefore, for the marine environment with high temperature and high humidity, the utilization efficiency of super (super) oxide is low and the cost is high.

In addition, per (super) oxides have strong oxidizing properties, and their particles volatilized into the atmosphere are not only corrosive to equipment, but also cause damage to the human respiratory system, which brings unfavorable factors to the control of gas environment

However, electrolyzed water consumes a lot of electricity and costs a lot

[0004] In summary, no matter what kind of oxygen generator in an underwater confined space, there are problems such as high cost and inability to improve concealment
