Description

Air circulation purifier in conventional submarine

Technical Field

Background

The submarine cabin atmospheric environment detection research is paid attention to by naval of various countries. The importance of submarine atmosphere quality is ranked as the second place in many countries, and the importance degree of the submarine atmosphere quality is sufficient. Most countries detect hundreds of components from submarine air, and China detects 652 components from submarine cabin air. On submarines, CO2 is a hazardous gas. The concentration of CO2 in the atmosphere is usually 0.03%, and the safety concentration of the gas on the submarine is usually 0.5% -1.0%. When the concentration is higher than this range, the crew may feel uncomfortable and even may have difficulty in completing the work. Therefore, when the CO2 concentration on the submarine exceeds the standard, certain removal techniques must be employed to reduce the concentration.

Since the birth of submarines, researchers in various countries have conducted extensive and extensive studies on CO2 purification techniques suitable for use in submarine cabins, and developed various types of CO2 purification devices, which are classified into physical purification methods, chemical adsorption methods, biological purification methods, and the like in principle. At present, the absorption of CO2 by the air purification device adopted by the submarine is mainly completed by the absorbent.

At present, a liquid-phase absorption process taking alcohol amine as an absorbent is generally adopted in a CO2 capture technology, and the process has the problems of corrosion in an absorption tower, easy decomposition and evaporation of the absorbent, easy foaming of a gas-liquid interface and the like. In contrast, adsorption processes based on solid adsorbents not only avoid the above problems of liquid phase absorption processes, but also have the potential of low energy consumption and low cost.
