Beneficial effect of the present invention is verified by following examples:
Embodiment one: a kind of fire safety temporary refuge device is made up of chamber 1 and chamber door 4; Described chamber 1 is 1/4 spheroid, and radius of sphericity is 1m; Described chamber 1 is made up of oxygen generator 2 and chamber body of wall 3; The cross section of described chamber door 4 is semicircle; Described chamber body of wall 3 is made up of bottom surface body of wall 5 and cambered surface body of wall 6; The bottom surface of described bottom surface body of wall 5 is semicircle; Described oxygen generator 2 is arranged in the left end of bottom surface body of wall 5; Described chamber door 4 is vertically set on the left side of bottom surface body of wall 5, and the arcwall face of described chamber door 4 is connected by cambered surface body of wall 6 with the arcwall face of bottom surface body of wall 5; Described bottom surface body of wall 5 is made up of the first fireproof coating layer 5-1, the first fireproof heat-insulating layer 5-2, first-phase change layer 5-3 and the second fireproof heat-insulating layer 5-4, sets gradually the first fireproof coating layer 5-1, the first fireproof heat-insulating layer 5-2, first-phase change layer 5-3 and the first fireproof heat-insulating layer 5-4 in described bottom surface body of wall 5 from the top down.Described cambered surface body of wall 6 is made up of the second fireproof coating layer 6-1, the 3rd fireproof heat-insulating layer 6-2, second-phase change layer 6-3 and the 4th fireproof heat-insulating layer 6-4, from inside to outside sets gradually the first fireproof coating layer 5-1, the first fireproof heat-insulating layer 5-2, first-phase change layer 5-3 and the first fireproof heat-insulating layer 5-4 in described cambered surface body of wall 6.
First fireproof coating layer 5-1 described in the present embodiment and the second fireproof coating layer 6-1 is refractory cement, thickness is for being greater than 20mm, described first fireproof heat-insulating layer 5-2, the second fireproof heat-insulating layer 5-4, the 3rd fireproof heat-insulating layer 6-2 and the 4th fireproof heat-insulating layer 6-4 are plate, brick or the blanket that alumina silicate is made, its thermal conductivity factor is lower than 0.05W/mk, thickness is greater than 100mm, described first-phase change layer 5-3 and second-phase change layer 6-3 is paraffin, fusing point is 35 ~ 65 DEG C, heat of solution is 173.6150kJ/kg, is no less than 30kg.Described chamber door 4 is double door, and its structure and material is identical with chamber body of wall 3.
Described oxygen generator 2 is cuboid container, and centre has dividing plate to separate, and lid is arranged at top, can close and open.Both sides are put enough water respectively and are produced oxygen species.Product oxygen species is calper calcium peroxide, and quality is no less than 0.8kg, and oxygen-producing amount at least enough two people breathes 2 hours.
When fire occurs, the outer temperature 400 DEG C of device, this has been very disadvantageous situation.If all areas of device are all heated, total heating surface amasss as 9.8m
2thickness from wall face to phase-change material is 150mm, mean coefficient of heat conductivity is 0.04W/mk, mean temperature time paraffin melting 50 DEG C, then be approximately 3293kJ to the heat of phase-change material transmission per hour outward by chamber, and the paraffin of 30kg is according to its heat of solution, can the constant absorption heat of at least 1.5 hours.Paraffin temperature is the highest during this period can not more than 70 DEG C, the heat that now can be delivered in chamber through heat-insulating shield is again little, namely such scheme can make refuge chamber keep the normal temperature of long period, the quality increasing paraffin can improve the duration, also can prevent the unfavorable situation that outer surface temperature is too high.
Entering the personnel that take refuge in chamber, open oxygen generator, calper calcium peroxide is put into water, producing oxygen for breathing.An adult needs the oxygen breathing 15L for one hour, i.e. 21.45g, if taking refuge is 3 people, then and one hour needs oxygen 64.35g.Purity is the calper calcium peroxide product of 80%, and often producing 1g oxygen approximately needs 5.7g.So the calper calcium peroxide amount being 80% for the three personal breathings purity of 1 hour is 366.8g.Therefore put into the calper calcium peroxide of 0.8kg, even if purity is not high and can not complete reaction, also can meets people and breathe.By putting into the calper calcium peroxide amount of water, control reaction rate, to keep oxygen concentration suitable in chamber.
