Temperature-reducing and dehumidifying device for mine refuge underground chambers

Abstract

The invention provides a temperature-reducing and dehumidifying device for mine refuge underground chambers, aiming to resolve the problem that a plurality of new unsolvable problems are brought forth when an air-conditioner is directly used in a refuge underground chamber. The temperature-reducing and dehumidifying device has the characteristics that a liquid carbon dioxide steel bottle, a high-pressure gauge, a main valve, a throttle valve, a heat power expansion valve, an evaporator, a low-pressure gauge, a reversing valve and a pneumatic blower are sequentially connected with each other through a pipe line, the liquid carbon dioxide steel bottle is arranged in a transition region, and the rest of the parts are arranged in a residential area. The invention provides the reliable temperature-reducing and dehumidifying device for the refuge underground chambers, which can work independently after a mine accident happens, thereby having great significance to the guarantee of the life safety of miners and prolonging the rescuing time.

Description

technical field [0001] The invention relates to a cooling and dehumidifying device, in particular to a cooling and dehumidifying device for a mine refuge chamber. Background technique [0002] Setting up and using emergency refuge chambers in underground mines is an important measure in mine emergency rescue. [0003] Mine disasters such as explosions, impacts, fires and other accidents will cause harsh high-temperature environments in the mine. In the refuge chamber, the metabolism of the trapped people will continuously generate heat and moisture. Therefore, how to solve the problem of heat and water vapor accumulation in the confined space, that is, solve the problem of cooling and dehumidification, is the most difficult part in the study of refuge chambers. [0004] Generally, the refuge chamber uses the mine's inherent ventilation system to cool down and dehumidify, and the inherent ventilation system under the mine is connected to the refuge chamber. However, after ...

AI Technical Summary

Problems solved by technology

[0005] Most foreign refuge chambers use electric air conditioners to control the temperature. The main unit of the air conditioner can be placed inside the refuge chamber, while the compressor must be installed outside. Therefore, the explosion-proof problem of the air-conditioning compressor outside the refuge chamber is not easy to solve.

In addition, the air conditioner needs to have enough power to maintain the operation of the air conditioner, and the external power is very likely to be interrupted in the event of a mine disaster
