Abstract

The invention provides a mine refuge chamber compressed air cooling device based on chemical refrigeration. The mine refuge chamber compressed air cooling device comprises a chamber, wherein the interior of the chamber is divided into an entrance air accumulation chamber, a middle cold accumulation box and an exit air accumulation chamber; condensation pipes are arranged inside the cold accumulation box; the entrance air accumulation chamber communicates with a compressed air pipeline of a refuge chamber; and a chemical refrigerant is arranged inside the cold accumulation box. The invention further provides a method for cooling the compressed air in the mine refuge chamber. The mine compressed air is cooled to 15 DEG C or below through the condensation pipes, and the cooled compressed air is sent into the living room environment of the mine refuge chamber, and the purpose that the indoor environment temperature of the refuge chamber is controlled to be 35 DEG C or below within 96 hours is achieved. According to the mine refuge chamber compressed air cooling device based on chemical refrigeration and the cooling method, the power provided by mine compressed air is fully utilized, the mine refuge chamber is cooled without power drive, the electric drive is not required, the system size is small, the cold energy is easy to store and get, the applicable environment temperature range is wide, the maintenance is avoided, the method is easy to implement, and the potential safety hazard is avoided.

Description

technical field [0001] The invention belongs to the field of mine safety and refrigeration, in particular to a chemical refrigerant-based mine compressed air cooling device and a method for cooling compressed air in a mine refuge chamber by using the device. Background technique [0002] With the advancement and development of science and technology and the improvement of the awareness of the rights and interests of human life, as an emergency avoidance facility for the protection of human life after disasters and accidents, mine refuge chambers are used for the survival of miners in distress after disasters and accidents in mines. Safety plays a major role and has received widespread attention from the mining industry at home and abroad. The cooling system of the coal mine refuge room should meet the requirements of no high-power and large-capacity power supply, no safety hazard, easy maintenance or maintenance-free, economical and practical. When a disaster accident occur...
