Air purifying device of coal mine underground emergency system

Abstract

The invention discloses an air purifying device of a coal mine underground emergency system. The air purifying device of the coal mine underground emergency system comprises a purifying box, the top end and the bottom end of the purifying box is provided with an air inlet duct and an air outlet duct respectively, the inside of the purifying box are sequentially provided with, from top to bottom, a drying unit, a carbon monoxide absorbing unit and a carbon dioxide absorbing unit which are used for purifying air, and the bottom of the purifying box is provided with a pneumatic fan which can extract air inside the emergency system into the purifying box. According to the structure above, by means of the pneumatic fan arranged at the bottom of the purifying box, the air inside the emergency system can be extracted out and flow out of the purifying box from the bottom of the purifying box, toxic and harmful air or water can be purified through the air purifying units and further the gas content of the coal mine underground emergency system can be in a normal state; gas content suitable for normal living of people can be discharged inside the coal mine underground emergency system through the air outlet duct, further the function of air purification can be achieved.

Description

[0001] technical field [0002] The invention relates to an accessory device used for the internal gas purification of an emergency escape system in a coal mine, in particular to an air purification device for an emergency escape system in a coal mine. Background technique [0003] As a coal mine safety emergency rescue equipment, the coal mine emergency avoidance system can provide a closed living space for miners who cannot evacuate the mine in time when a disaster occurs. During the period when there are people in danger, the carbon monoxide, carbon dioxide, water and other toxic and harmful gases such as hydrogen sulfide excreted by the human body, as well as the toxic and harmful gases such as methane brought into the cabin by the personnel entering the cabin, can only be rescued from life. The air in the rescue cabin cannot meet the normal needs of the human body of the escaped personnel, thus causing damage to the life safety of the escaped personnel. Contents of th...
