In addition, a buckle can be installed on the inner side of the top plate 102 of the inner layer 201, and a micro oxygen tank can be movably clamped on the buckle for providing enough oxygen when a plurality of people enter the inner layer 201.
In the practical test, the technical scheme has good test effect:
the test method is as follows:
1. test conditions: the heat conductivity coefficient of the barrier curtain is 0.02-0.045W/mK, and the density value is 1200kg/m < 3 >; the heat conductivity coefficient of the building wall layer and the ground layer is 0.9
W/mK, density is 2700kg/m 3. Water flow rate 0.5L/s, specific heat 42000
J/kg ℃, the convection heat transfer coefficient is 1500W/(m 2 ℃). The outside temperature of the barrier curtain was 1000 ℃.
2. The testing method is that the burning device is arranged at the left side and the right side of the periphery of the device to burn continuously at high temperature.
3. Test results: the temperature outside the whole barrier curtain is very high (approximately 1000 ℃), which is mainly heat conduction and heat radiation at the time of fire. The heat insulation layer has a larger temperature gradient, the temperature is directly reduced from 1000 ℃ to below 100 ℃, and the heat insulation capability (such as thickness and heat conductivity coefficient) of the barrier curtain is an important factor for ensuring that the temperature in the refuge cabin is lower than a specific value, namely, the normal survival operation of personnel in the cabin is met. Within 2 hours, the temperature of the inner surface of the refuge cabin is about 30 ℃, so that the personnel can be ensured not to cause thermal injury to human bodies due to heat radiation and heat convection in the space.
Through test data can learn, introduced bilayer structure and water-cooling technical scheme after, the effect of the self-rescue device of the technical scheme of this application improves by a wide margin, adopts different thickness, can further improve thermal-insulated efficiency.
