An environmental control and life protection system for underground refuge chambers in coal mines

Abstract

The invention discloses an environmental control and life support system for an underground refuge chamber for a coal mine. The environmental control and life support system comprises an oxygen generating device for generating oxygen through an oxygen generating device, a refrigerating device for generating cool air by means of reacting with a phase-change material by using heat generated in an oxygen generating process, an eddy current refrigerator which is connected with the refrigerating device and is used for controlling the temperature of the phase-change material, a carbon dioxide absorption platform for removing carbon dioxide in air, and a carbon monoxide catalyzing device for removing carbon monoxide in the air. The environmental control and life support system provided by the invention uses the oxygen generating device to carry out a pure chemical reaction to generate oxygen without an electric energy source, uses the refrigerating device to remove the heat generated by the oxygen generating device and cool the cool air supplied for the refuge chamber simultaneously, and has the advantages of no need of manual control in an entire process, environmental friendless and energy conservation. The absorption of indoor carbon dioxide and carbon monoxide can be further enhanced through the carbon monoxide catalyzing device and the carbon dioxide absorption platform. Furthermore, the carbon monoxide catalyzing device and the carbon dioxide absorption platform can work without electric power, so that the electric resource in the refuge chamber is greatly saved.

Description

technical field [0001] The invention relates to a coal mine life support system, in particular to an automatic processing device for producing oxygen and cold air in an underground refuge chamber of a coal mine. Background technique [0002] In the prior art, the underground refuge chambers of coal mines all use compressed oxygen oxygen supply mode for oxygen supply, but the carbon dioxide content in the air cannot be eliminated, so electric filter equipment can only be used for carbon dioxide treatment, which requires a long-lasting power supply, but once the coal mine Underground catastrophes are often accompanied by power outages, and it is difficult to last as long as only backup power is used. In addition, the catastrophe is accompanied by high temperature conditions. The cooling measures in the chamber usually use ice-making cold storage or carbon dioxide refrigeration to cool down. Ice-making cold storage requires electric power, and carbon dioxide refrigeration will ...
