Potassium superoxide medical plate for underground emergency refuge air regeneration device in coal mine and method

Abstract

The invention discloses a potassium superoxide medical plate for an underground emergency refuge air regeneration device in a coal mine. The potassium superoxide medical plate comprises the following raw materials in part by weight: 94 to 96 parts of oxygenating and carbon absorbing medical powder and 4 to 6 parts of reinforcing agents; and the oxygenating and carbon absorbing medical powder comprises 75 to 85 weight percent of KO2, 8 to 13 weight percent of K2O2 and 7 to 12 weight percent of K2O. According to the potassium superoxide medical plate, the content of all active ingredients is appropriate, so that the oxygen releasing rate is reduced, the oxygen is stably and reliably generated, and the ratio of the absorbed carbon dioxide to the released oxygen is matched with the respiratory quotient of a human body; by adding auxiliary adding agents, the porosity of the medical plate is increased under the condition that the structural strength is not changed, so that the carbon dioxide penetration capacity is improved, and absorption of the medical plate to the carbon dioxide is promoted; and the humidity application range of the medical plate is expanded to over 90 percent, but the humidity application range of the conventional potassium superoxide medical plate is not more than 60 percent. The potassium superoxide medical plate is suitable for closed large spaces, high-temperature and high-humidity environments and crowded places.

Description

technical field [0001] The invention relates to an air regenerating device, in particular to a special potassium superoxide medicine plate for an emergency avoidance air regenerating device in a coal mine and a preparation method thereof. Background technique [0002] The "six major systems" for coal mine safety avoidance include detection and monitoring system, underground personnel positioning system, underground emergency avoidance system, mine pressure wind self-rescue system, mine water supply rescue system and mine communication system. Among them, the coal mine emergency avoidance system is the key work in the construction of the "six major systems" of safety avoidance. Coal mine emergency avoidance system refers to an organic whole composed of facilities, equipment and measures to provide life support for people in distress in case of emergency in coal mine. In the past two years, coal mining enterprises across the country have vigorously promoted the construction o...

[0055] In addition to the dangers of high-pressure oxygen cylinders themselves, high-pressure oxygen cylinders also have self-leakage, and the instantaneous leakage of high-pressure gas will also affect the lives and health of personnel, especially the high leakage rate of oxygen cylinders in China, which increases the risk factors; high-pressure oxygen cylinders need It is transported to the ground once a year for gas replenishment, and transported to the ground professional organization for inspection of steel cylinders every three years, and the maintenance cost is also high
