Description

Gas mask with air purification function {GAS MASK HAVING AIR CLEANING ABILITY}

The present invention relates to a gas mask equipped with an air purification function.

Conventional gas masks are divided into military gas masks, industrial gas masks, and special gas masks, and thus generally commercialized small gas masks can be said to be extremely insignificant. Even if a small gas mask is provided with a limited function, it can be said that it is insufficient as a gas mask that can proactively cope with an emergency such as a fire or a NBC.

In general, a gas mask is a tool for protecting a face from inhalation or adhesion of smoke, addictive chemical agents, biological agents, and radioactive agents. Such gas masks are used in coal mines and factories as well as in wars. Since coal mines and factories emit toxic gases, vapors, and toxic particulates, gas masks are used to defend against these polluted environments. It is also often used by firefighters and police officers for fire fighting and riot suppression. We are equipped with gas masks in the subway station and in the vehicle following the subway fire accident in Daegu in 2003.

Such a gas mask comprises a face part made of rubber and plastic, a purifying container connected to the face part, and a portable bag. Septic tanks are used to purify toxic gases with clean air. These containers contain absorbents that chemically adsorb or decompose toxic gases, and also contain filters or filters that physically filter out particulate matter. Depending on which agent is used, an absorbent can be used to effectively purify the agent. However, since military agents cannot predict which agent will be used, a wide range of specially treated activated carbon is used as the absorbent.

The ACF layer 130 may function as a gas filter capable of purifying the toxic gas in the intake air.

Herein, activated carbon fiber (ACF) is an adsorption material that has developed micro pores dl having an average size of 0.1 to 5 μm, and may be manufactured by the following method.

Activated carbon fibers (ACF) are carbonized by heating the fabric under an inert gas atmosphere, which is a reducing atmosphere, and activated at a high temperature, so that activated carbon fibers having developed most of the micropores can be produced.

The fabric may be a non-woven fabric, a woven fabric, a tricoat, or the like, and the activated carbon fibers are filled in the air purification filter body 120 of the gas mask 100. By improving the performance of the air purification filter body 120, the volume can be reduced in size, thinner.

Activated carbon fiber (ACF) with fine pores is classified into BET specific surface area and adsorptive capacity according to the peculiar characteristics of pitch system, PAN system, cellulose system, etc. The specific surface area of 1,250 ~ 1,500㎡ / g, can be divided into 1,000 ~ 1,250㎡ / g in the third grade.

The gas filter is filled with a plurality of activated carbon fiber filters 132 stacked and filled with various activated carbon fiber filters 132 with or without various types of metal catalysts depending on the type and concentration of the toxic agent. The activated carbon fibers constituting the ACF layer 130 may have the same shape as one side of the air purification filter body 120 to be accommodated inside the air purification filter body 120. Can be.

That is, if the shape of the air purification filter body 120 is a cylindrical shape, the activated carbon fibers are also formed in a circular shape, and if the shape of the air purification filter body 120 is a rectangular cylinder shape (cuboid shape), the activated carbon fibers are also formed in a square shape. Can be.

In addition, the edge of the activated carbon fibers constituting the ACF layer 130 may be formed with a fixed edge (not shown) having a predetermined thickness.

In this case, the thickness of the edge may be preferably determined to 0.4-4mm in consideration of the size of the air purification filter body 120 and the thickness of the activated carbon fiber.

At this time, if it is less than 0,4mm, the manufacturing cost may increase, and if it is more than 4mm, the volume occupied in the gas mask 100 may be excessively large, and thus, it may be difficult for the activated carbon fiber to exhibit proper function.

As a material that can form the edge of the air purification filter 182, it may be formed using a hot melt (polyolefin-based, polyamide-based, acrylic, polyurethane-based, EVA (ethylene-vinyl acetate copolymer)) .

The shape of the edge of the ACF layer 130 may be round or square depending on the shape of the activated carbon fiber. In addition, when one side of the air purification filter body 120 has a convex curvature, the shape of the edge constituting the ACF layer 130 corresponds to one side of the air purification filter body 120. It may have a rectangular shape having a curvature.
