Carbon Dioxide Purification Test of Mine Rescue Capsule

The rescue capsule is the equipment that provides hedging for survival trapped in confined spaces in the mine accident. In the process of waiting for help, the most important issue of the cabin air purification system is the treatment of carbon dioxide gas pollutant produced by human body. In the article, it carried out a series of tests for carbon dioxide purification as capsule working and had test validation by real life simulation. CO₂ processing capacity as no-load test was not less than 0.5 L/min per person; the higher wind speed of purification device was, the more powerful of purification for the carbon dioxide. In the honorable person simulation test, the 24.2 kg medicament may supply 10 people to use 17 h.
