Example Embodiment

[0012] A filter screen 5 is arranged on the upper surface of the support frame 4, and a CO adsorbent 1 and CO can be adsorbed on the filter screen. 2 Adsorbent 2 and other harmful gas adsorbent 3, the filter screen is filled with activated carbon. The pneumatic fan 7 is installed under the support frame. The power input of the pneumatic fan is connected to the mine air pressure system or the air-conditioning system of carbon dioxide refrigeration. The muffler 6 is installed on the pneumatic fan to reduce the noise generated by the gas flow and reduce the interference. Damage to the human auditory system creates a relatively comfortable environment. The compressed air system or the carbon dioxide refrigerated air conditioning system drives the pneumatic fan to rotate, forming a negative pressure on the pneumatic fan, so that the air in the refuge chamber passes through various adsorbents, and the carbon monoxide, carbon dioxide, toxic and harmful gases and dust in the refuge cham...

Abstract

The invention provides an air purification device of an underground refuge chamber, and aims to solve the problems of adopting lithium hydroxide to manufacture an absorbing curtain and hanging the absorbing curtain in the chamber to absorb or remove poisonous and harmful gases, such as CO2, and the like. The prior equipment needs to occupy a large amount of space when in use and has a poor adsorption effect. The key points of the air purification device lie in that a filter screen is arranged on a support frame; an adsorption material capable of adsorbing gases of CO and CO2 is arranged on the upper surface of the filter screen; a pneumatic fan is mounted below the support frame; and a power input end of the pneumatic fan is connected with a mine pressure ventilation system or a carbon dioxide refrigerating air-conditioning system. The air purification device is used in the refuge underground chamber for purifying air of the refuge underground chamber.

Description

technical field [0001] The invention relates to an air cleaning device, in particular to an air cleaning device used in underground refuge chambers of coal mines. Background technique [0002] A variety of toxic and harmful gases that may appear in the refuge chamber in the coal mine accident state, especially carbon monoxide and carbon dioxide produced by the respiration of the refuge personnel in the chamber, are processed. If CO 2 Without effective treatment, it will continue to accumulate, and when the concentration reaches more than 3%, it may pose a threat to human life. Therefore, the main task of the indoor air purification equipment in the refuge is to remove CO 2 . The present invention can convert CO 2 The concentration is controlled below 1%. The sources of CO mainly include the following two parts: one is the catastrophic ambient gas in the roadway introduced when the refugees enter the cabin, and the other is the trace amount of CO produced by the human bod...
