Problems solved by technology

Compressed oxygen is the most commonly used in medicine, but limited by its storage conditions, there are major safety hazards, large space occupation, and high maintenance costs; chemical oxygen supply is divided into superoxide oxygen supply and chlorate oxygen candle oxygen supply , the superoxide oxygen supply process will expand and paste due to the absorption of oxygen containing moisture, which is less efficient and corrosive; the oxygen supply of chlorate oxygen candles has the advantages of small volume, large oxygen storage capacity, and rapid oxygen release. Low storage conditions, easy for long-term storage, especially suitable for oxygen supply in confined spaces
[0003] At present, most of the oxygen candle equipment for oxygen supply in confined spaces on the market stays in the manual "ignition" technology, and the degree of intelligence is low. For confined spaces with a large oxygen demand, a single oxygen candle often cannot meet the oxygen supply requirements. However, multiple oxygen supply at the same time will cause disadvantages such as high temperature and uncontrollable concentration. It is particularly important to realize automatic monitoring and release oxygen multiple times.

Description

technical field [0001] The invention belongs to the technical field of oxygen absorption in a confined space, and in particular relates to an intelligent group type oxygen releasing device and method. Background technique [0002] Oxygen release device is one of the necessary components of life support system in confined space. At present, the oxygen supply technology in confined spaces mainly includes three ways: compressed air oxygen supply, compressed oxygen oxygen supply and chemical oxygen supply oxygen supply. The premise of compressed air oxygen supply is that the compressed air system in the confined space is not damaged or the external environment is not polluted. Therefore, the confined space must have independent oxygen supply capability. Independent oxygen supply technology is mainly compressed oxygen and chemical oxygen production. Compressed oxygen is the most commonly used in medicine, but limited by its storage conditions, there are major safety hazards, la...
