Description

{Protective clothing for fire shelter}

More particularly, the present invention relates to a protective garment for fire escape, and more particularly, to a protective garment for fire escape, which is formed of a multi-end flame retardant fabric and a multi-end flame retardant fabric for impact relaxation which can expand the volume when a fire occurs, The present invention relates to a protective garment for fire escape which can improve respiration during evacuation by providing an adsorbent and can increase the probability of securing the victim's golden time until the structure is constructed.

Many buildings now have a variety of fire extinguishers, such as fire detectors to prevent fires in case of fire, fire extinguishers and sprinklers to prevent fire. However, in the event of a large fire that can not be suppressed by the above fire fighting tools, rapid evacuation will be the only way to reduce the fire damage. However, if it is impossible to evacuate as quickly as when it is trapped in an enclosed space, it is inevitable to wait for the structure of the rescue personnel in the scene of a terrible fire. Therefore, there is an urgent need to protect the body from fire, toxic gas, and falling objects during the golden time until the structure of the rescue crew is made.

As a conventional method of evacuating in the event of fire, Korean Patent Laid-Open Publication No. 10-2017-0055349 discloses a backpack for evacuating a newborn from flames in the event of a fire, and Korean Patent Application Laid-Open No. 20-2010-0006465 There is disclosed a one-touch flame retardant and flame-retardant aramid tent for evacuation when a fire occurs, Korean Utility Model Publication No. 20-2016-0003725 discloses an emergency escape capsule for evacuation when a fire occurs, There are a number of methods.

However, in the case of a newborn shelter, there is a disadvantage in that it is difficult to breathe because oxygen is not supplied to the closed space in the backpack during evacuation. In case of one-touch flame retardant and fireproof aramid tent and emergency escape capsule, There is a problem that it is difficult to prevent choking.

Therefore, the present inventor can enhance the probability of securing the victim's golden time until the structure is constructed by using a fire protection suit for fire escape which can not only protect the body from external impacts in the event of a fire but also facilitate breathing And finally completed the present invention.

And a multi-endotheque for relieving the impact, according to an embodiment of the present invention.

1, 2, 3 and 4, the protective clothing for fire escape according to the present invention includes a head 100 on which a sight window 110 and a breathing outlet 120 are formed; An oxygen supply line (130) inserted into an inner space of the head part and having one end exposed inside the head part to introduce oxygen; An oxygen generator 140 installed at the other end of the oxygen supply line; A body 200 detachably coupled to the head; And a carbon monoxide adsorbent (300) formed on the coupling part where the head part and the body part are coupled, wherein the protective garment includes a cover (210) made of flame retardant fabric, And a gas generator (230) provided between the multiple endothelium for shock mitigation and supplying gas between the multiple endothelium for shock mitigation.

The protective garment for fire escape is provided with an oxygen generator 140 generating oxygen and an oxygen supply line 130 through which the generated oxygen is introduced into the protective clothing. The carbon monoxide adsorbent 300 for adsorbing carbon monoxide and the breathing exhaust 120) is formed, it is possible for the victim to have normal breathing during the golden time before rescue. In addition, since the envelope 210, which is in direct contact with the fire or under the influence of high temperature, is safe from high temperature due to the use of the flameproof material and the gas discharged from the gas generator 230 provided between the multiple endo- It is possible to expand the volume of the multi-endothelium for shock mitigation to protect the body against collapse of the building caused by fire.

In addition, a field of view can be secured through the sight window 110 formed in the head 100, and carbon dioxide generated by respiration of a human being through the breathing outlet 120 can be discharged.

The carbon monoxide adsorbent 300 may be at least one selected from the group consisting of impregnated activated carbon, zeolite exchanged with copper ion, alumina coated with copper ion, and MOF (porous metal organic skeleton), and is not limited thereto. Impregnated activated carbon may be used, and the carbon monoxide adsorbent may be used in the form of a circular band using Gore-Tex.

The impregnated activated carbon means activated carbon in which metals such as manganese and copper are immobilized. It can act as a catalyst for promoting the oxidation reaction in which carbon monoxide is converted into carbon dioxide as well as the carbon monoxide is adsorbed and removed at the solid surface at room temperature.

As a specific example, according to Roginskii's theory on the above reaction, MnO ₂ adsorbs CO first by the MnO ₂ catalyst, and then the adsorbed CO is oxidized to CO ₂ through two steps.

From this, impregnated activated carbon selectively adsorbs carbon monoxide rather than carbon dioxide, which is suitable for removing toxic gases in case of fire.

6, the first holes 141a and 141b are blocked at the upper surface of the second storage part 142 before the rotation of the second storage part. Then, as shown in FIG. 7, The first holes 141a and 141b are disposed at the same positions as the second holes 142a and 142b so that the catalyst flows into the second storage portion 142 and the hydrogen peroxide And the generated oxygen is discharged to the oxygen supply line 130 through the discharge port 143. The oxygen is supplied to the oxygen supply line 130 through the discharge port 143,

In addition, the weight ratio of the catalyst and the hydrogen peroxide may be 1: 2500 to 3000, preferably 1: 2850 to 2950. When the weight ratio of the catalyst and the hydrogen peroxide is in the above weight ratio range, the oxygen concentration is maintained at 20 to 25% by volume in the closed space, so that the normal breathing can be enabled during the golden time before the victim is rescued. If the weight ratio is out of the range, it is difficult to maintain the oxygen concentration in the above range.

The catalyst may be at least one selected from manganese dioxide, potassium iodide, carbon powder, and catalase, but is not limited thereto. Manganese dioxide may be preferably used.

Further, the outlet 143 may be blocked by a gore-tex film. The Gore-Tex membrane is a fiber which is made to pass small molecules such as gas and not to pass large molecules such as water. Therefore, it is possible to safely store hydrogen peroxide and manganese dioxide having a molecular size larger than that of water molecules, and when oxygen is generated, oxygen is easily discharged.

Hereinafter, production examples and embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

9 is an image showing a process of measuring the thermal conductivity of carbon fiber by using a thermal conductivity meter.

The method of measuring the thermal conductivity of carbon fiber is as follows. The carbon fiber was installed in the 6-7 section of the thermal conductivity meter shown in FIG. 9, and the cooling water was passed through the flow meter to the lower portion by a certain amount. Next, the power of the thermal conductivity meter was turned on, and the heater and the heater controller attached to the thermal conductivity meter were used to raise the electric power. Next, the changeover switch of the temperature indicator is switched to measure the temperature of the steady state in the 10th, 7th, and 6th intervals, and the calorie of the experimental equipment is calculated through the following Equation 1, and the thermal conductivity of the carbon fiber is calculated by the following equation Respectively. The steady state temperatures of the 10th, 7th and 6th sections were measured at 255 ° C, 254 ° C and 72 ° C, respectively.

In the following Equation 1, the thermal conductivity K _steel of the experimental equipment is 73 W / m · k, the cross-sectional area A of the 7th to 10th sections is 12.6 × 10 ^-4 m ² , (ΔT ₁ ) is (528-527) K, and the length (L ₁ ) of the 7th to 10th intervals is 0.1 m.

The cross-sectional area (A _{c .f} ) of the carbon fiber is 12.6 × 10 ^-4 m ² , the thickness (L ₂ ) of the carbon fiber is 10 ^-3 m, and the temperature difference ΔT ₂ ) was calculated by referring to (527-345) K. As a result, it was confirmed that the thermal conductivity of carbon fiber was 0.01003 W / m · K.

[Equation 1]

&Quot; (2) "

Table 1 below shows the thermal conductivities for various gases, liquids and solids types.

gas Liquid solid Kinds Thermal conductivity
(W / mK) Kinds Thermal conductivity
(W / mK) Kinds Thermal conductivity
(W / mK) vapor 0.25 Engine oil 0.14 Glass fiber 0.038 helium 0.15 glycerin 0.28 tree 0.1 air 0.26 water 0.59 Glass 0.878 carbon dioxide 0.25 Mercury 8.69 Stainless steel 19 Oxygen 0.02 iron 73 nitric acid 0.02 aluminum 204 Copper 386 silver 419 Magnesium board 0.24 CRC board 0.24 Glass wool 0.042 Mineral wool (calcium silicate) 0.044 Hard urethane 0.024 Aramid fiber 0.05

Referring to Table 1, it can be seen that the thermal conductivity (0.01003 W / m · K) of the carbon fiber is considerably lower than that of a typical solid and liquid, and is lower than that of a gas having a low thermal conductivity. In addition, it can be confirmed that it is the most suitable fabric as the outer cover of the fire protective clothing, considering that the heat conductivity of the heat insulating material is generally lower than that of the aramid fiber which is the main fiber of the fire fighting clothing.

10 is a graph showing a respiration model at an ideal reaction rate constant (K = 0.009 min ^-1 ) when human respiration and hydrogen peroxide decomposition reaction occur simultaneously in a closed space.

The ideal reaction rate at which the oxygen concentration was maintained at 20 to 25% by volume when hydrogen peroxide decomposed in the closed space and oxygen was generated was calculated, and the ratio of hydrogen peroxide and manganese dioxide showing the ideal reaction rate was determined.

(1) Calculation of ideal reaction rate constant

A closed volume of 70 L volume was set, and the initial oxygen concentration of the closed system was measured as 21 vol% and the nitrogen concentration was measured as 79 vol%. The respiration process was performed once every 4 seconds with reference to the literature. In the exhalation (0.5 L), 74.5% by volume of nitrogen (0.0785 L), 15.7% by volume of oxygen (0.3725 L) , And 3.6 vol% of carbon dioxide (0.018 L).

The volume of each component after the breathing is calculated in the closed system, and the value (mol) obtained by dividing the volume of each component by the non-volume after respiration is added to the value (mol) of additional product gas generated due to the hydrogen peroxide decomposition reaction, Was determined. The volume of each component was then calculated by multiplying the number of moles of each component by the non-mass, and the volume of each component after respiration was calculated. The above calculations were repeated to determine the reaction rate constant at which the oxygen concentration was maintained at 20 to 25% by volume to obtain the ideal reaction rate constant. As a result, an ideal reaction rate constant k was calculated to be 0.009 min ^-1 .

Referring to FIG. 10, when human respiration and hydrogen peroxide decomposition reaction occur simultaneously in the closed space, the oxygen concentration is maintained at 20 to 25% by volume for 15 minutes at the ideal reaction rate constant (k = 0.009 min ^-1 ) can confirm.

(2) Determination of the ratio of hydrogen peroxide and manganese dioxide

The rate constants of hydrogen peroxide degradation were measured by the following method.

First, 7.9 g of potassium permanganate was taken in a 100 ml volumetric flask, and a small amount of distilled water was added thereto, followed by shaking to completely dissolve the solution. The scale was filled with distilled water to prepare a 0.5 M potassium permanganate solution. Then, potassium permanganate standard solution prepared by adding 5 ml of sulfuric acid to 100 ml of the prepared 0.5 M potassium permanganate solution was prepared and used to titrate the initial concentration of the hydrogen peroxide solution (end point of disappearance of the faint pink). Then, 0.1 g of manganese dioxide was added to 200 ml of the hydrogen peroxide solution, and the reaction was carried out. After the reaction for 4, 8, 12 and 16 minutes, the concentration of the hydrogen peroxide solution was titrated with the standard potassium permanganate solution. The titration was repeated by varying the amount of manganese dioxide to 0.1 g, 0.2 g and 0.3 g.

Table 2 shows the appropriate amount of hydrogen peroxide according to the reaction time. The concentration of the hydrogen peroxide solution according to the reaction time was calculated using the following Table 2 and the following Table 3, and the results are shown in Table 3 below.

Next, the reaction rate constant at the decomposition of hydrogen peroxide according to the amount of manganese dioxide was calculated using the concentration of the hydrogen peroxide solution according to the reaction time in Table 3 and the following Equation 4 and Equation 5 (least squares method) Are shown below.

(2) The reaction rate constants were calculated through the above calculation process even under the conditions of 0.2 g and 0.3 g of manganese dioxide, and the results are shown in Table 4 below.

Referring to Table 4 below, it was confirmed that the ratio of hydrogen peroxide and manganese dioxide, which exhibits the most similar reaction rate to the ideal reaction rate k = 0.009 min ^-1 , is the case of using 0.1 g of manganese dioxide under the condition of using 200 ml of hydrogen peroxide.

11 is a schematic view briefly showing an experiment for measuring the impact relaxation effect of a nylon tube filled with carbon dioxide gas of the present invention. The above impact reduction effect measurement experiment was carried out as follows.

First, the nylon tube was filled with about 1.5 times the volume of the tube of carbon dioxide and fixed on the floor. Two pieces of iron balls (1.03 kg) were prepared, and a straight friction plate (A) one side of the iron ball is placed on the tube to some extent (A), and one side of the iron ball is closely attached to the tube (B). If you roll the iron ball over the tube with a moderate force, the iron ball on the tube is pushed out. The distance and time of both sides were checked to find the speed, and then the momentum was calculated to obtain the difference. The measurement of the momentum was repeated to obtain an average of the amount of change in the amount of exercise (the amount of the impact), and the results are shown in Table 5 below.

As shown in the following Table 5, the average amount of change in the momentum is calculated, and it is understood that the amount of the shock is absorbed by about 1.47 ± 0.25 kg · m / s. This means absorbing about 96.8% of the impact.
