Chemical cooling method and device for mine refuge chamber and rescue cabin

Abstract

The invention discloses a chemical cooling method and a device for a refuge chamber and a rescue capsule of a mine; the method comprises the following steps that chemical refrigerant is filled in a reaction chamber; the chemical refrigerant is subjected to heat absorption reaction in the reaction chamber; hot air in the refuge chamber or the rescue capsule exchanges heat with the reaction chamber and is cooled into cold air; and the heat exchange between the hot air in the refuge chamber or the rescue capsule can be carried out through radiation or forceful air supply by a fan. According to the chemical cooling method and the device for the refuge chamber and the rescue capsule of the mine, the chemical refrigerant has heat absorption reaction to form a refrigeration source, the hot air in the refuge chamber and the rescue capsule exchanges heat with the refrigeration source to be cooled, so that the purposes of cooling and refrigerating in the refuge chamber and the rescue capsule are achieved; the chemical refrigerant has the characteristics of convenience in carrying and use and simplicity in preparation, so that the method is convenient and quick, low in cost, safe and reliable, and does not need any external power; and in addition, the device has the advantages of simple structure, convenience in installation and maintenance, safety and reliability.

Description

technical field [0001] The invention relates to cooling and dehumidification technology for confined spaces such as mine refuge chambers and rescue cabins, in particular to a chemical cooling method and device for mine refuge chambers and rescue cabins. Background technique [0002] At present, the commonly used refrigeration methods for refuge chambers and rescue cabins in coal mines mainly include: ice storage refrigeration, compressor refrigeration, and phase change refrigeration. Using ice storage refrigeration, the ice machine makes water into ice and maintains the frozen state. The disadvantages are high energy consumption, difficult maintenance and high cost. Compressor refrigeration is used, and the refrigerator requires a large-capacity battery or an external high-power power supply. The disadvantage is that there is no external power supply after an accident in the coal mine, and the management and maintenance of the large-capacity battery is difficult, poor in rel...

AI Technical Summary

Problems solved by technology

Using ice storage refrigeration, the ice machine makes water into ice and maintains the frozen state. The disadvantages are high energy consumption, difficult maintenance and high cost.

The compressor is used for refrigeration, and the refrigerator needs a large-capacity battery or an external high-power power supply. The disadvantage is that there is no external power supply after an accident occurs in the coal mine, and the management and maintenance of the large-capacity battery is difficult, poor in reliability, and high in cost.

Phase change refrigeration is used, and the refrigerant is usually carbon dioxide. The disadvantage of this refrigeration method is that there are a large number of cylinders for storing liquid carbon dioxide, which takes up a large space, is difficult to maintain, and has potential safety hazards.
