Air regeneration system and control method thereof

Abstract

The embodiment of the invention relates to an air regeneration system and a control method thereof, relates to the technical field of air regeneration, and mainly aims to provide a safe, controllable and miniaturized air regeneration system and a control method thereof. The air regeneration system comprises a potassium superoxide agent feeder; a water feeder; an inlet of the carbon dioxide absorber is connected with a potassium hydroxide solution outlet of the mixed reaction oxygen generator, a spiral blade is arranged in the carbon dioxide absorber, the height of an outlet of the carbon dioxide absorber is lower than the top of the spiral blade and higher than the bottom of the spiral blade, and the air inlet channel is provided with an air inlet fan. And the carbon dioxide absorber is used for mixing a potassium hydroxide solution flowing in from the potassium hydroxide solution outlet with carbon dioxide in air entering from the air inlet channel. Compared with a spraying type carbon dioxide absorber, the spiral blade structure is adopted, a large spraying space does not need to be occupied, and therefore the size of an air regeneration system is easy to achieve miniaturization.

Description

technical field [0001] The embodiments of the present application relate to the technical field of air regeneration, and in particular, to an air regeneration system and a control method thereof. Background technique [0002] In confined spaces, such as air-raid shelters, mines, submarines, etc., the concentration of oxygen in the air and the concentration of carbon dioxide need to be kept within a certain range. Threats to life safety. [0003] To this end, in a confined space, potassium superoxide particles are usually configured as oxygen generators. During use, the staff can expose a certain amount of potassium superoxide particles to the air in the confined space, and the potassium superoxide particles will be in the air. The water vapor in it chemically reacts to generate oxygen and potassium hydroxide. At the same time, potassium hydroxide reacts with carbon dioxide in the air to form potassium carbonate, which can increase the oxygen concentration in the air and rem...

AI Technical Summary

Problems solved by technology

However, in the actual use of potassium superoxide particles, on the one hand, the reaction between potassium superoxide particles and water vapor is uncontrollable. Once the potassium superoxide particles are exposed to the air, the oxygen production process cannot be interrupted.

On the other hand, during the reaction process between the outer surface of potassium superoxide particles and water vapor, the potassium carbonate produced on the surface of potassium superoxide particles will form a paste-like coating layer, making it difficult to completely decompose potassium superoxide particles

At the same time, in the treatment of the used potassium superoxide particles, it is difficult for the processing personnel to distinguish whether they have completely reacted. During the treatment of the incompletely reacted potassium superoxide particles, since the incompletely reacted potassium superoxide is a strong oxidant, Improper, prone to dangerous accidents
