Electric drive-free cooling and dehumidifying device for refuge cabin

Abstract

The invention relates to an electric drive-free cooling and dehumidifying device for a refuge cabin, which belongs to the technical field of life saving apparatuses. The electric drive-free cooling and dehumidifying device for the refuge cabin is characterized by comprising a liquid CO2 gas bottle, a temperature control device and a dehumidifying and purifying device, wherein the temperature control device consists of a gas pressure regulation mechanism, a pneumatic motor and a cooling mechanism; the liquid CO2 gas bottle is connected with the gas pressure regulation mechanism; the gas pressure regulation mechanism is communicated with the pneumatic motor; the pneumatic motor is communicated with the cooling mechanism; and the cooling mechanism is connected with the dehumidifying and purifying device. The device has the advantages of ensuring the normal breathing and metabolism of human bodies, avoiding the secondary damage of harmful gases to refugees and simultaneously realizing filtration, cooling and dehumidifying functions by using a set of mechanism, along with high degree of integration, high refuge cabin reliability and safety, and the like.

Description

technical field [0001] The invention belongs to the technical field of lifesaving appliances, in particular to a non-electrically driven cooling and dehumidification device for a refuge cabin. Background technique [0002] At present, disastrous accidents such as gas explosions in coal mines, coal and gas outbursts, fires, and collapses have great destructive power, complex causes of accidents, and are accompanied by hypoxia, toxic and harmful gases, and high-temperature environments, which can easily cause secondary accidents, etc. features. Due to the complexity of the occurrence of the above-mentioned disasters, it is difficult for rescuers to rescue people in distress in time. The temperature and humidity of the refuge cabin are affected by the consumption of oxygen and food by the human body, forming the body surface temperature and relying on the body skin to dissipate heat. There is also a heat source from the outside space in the cabin, forming a temperature rise in...
