Description

Mask with high efficient filter to remove harmful gas and dust

(Purpose, conventional)

The present invention relates to a mask equipped with a high-performance filter that removes harmful gases and dust. More specifically, a person exposed to a severe air pollution atmosphere and a harmful environment due to exposure to harmful gases or a special environment in which toxic gases are emitted. In order to protect it from fine dust and harmful gas, high-performance filter paper which can remove even fine dust and harmful gas can be removed, and at the same time, it is filled with impregnated activated carbon and anti-infrared ray emitting ceramic which has antibacterial function to suppress microbial habitat. By using an ion exchange nonwoven fabric or impregnated activated carbon fibers instead of impregnated activated carbon in a high-performance filter or a high-performance filter manufactured in one piece, it is possible to manufacture a high-performance filter.

In addition, the high-performance filter can be mounted inside a general mask, and after the removal effect of harmful gas is reduced, the high-performance filter can be replaced, so that the mask is a mask with a high-performance filter that continues to be recycled.

The present invention provides a method of making a mask that can be easily worn to protect people in urban environments or workers who are exposed to hazardous environment or to human life in a special environment, and has excellent efficacy in removing fine dust and harmful gases. Has its purpose. In order to achieve the above object, the present invention consists of a method of manufacturing a high-performance filter and a method of inserting the same into a general mask.

Used to protect the health of workers working in industrial sites handling hazardous gases, urban residents with severe air pollution, and those exposed to harmful gases when spraying pesticides or to protect human life from military poisonous gases used for killing people in case of emergency. The most important of these masks is a filtration filter for removing dust from inhaled air and a purifier filled with impregnated activated carbon to remove toxic gases.

Impregnated activated carbon, which is one of the constituents of the septic tank, is used to remove harmful gases and improves the ability to adsorb and remove harmful gases by adding various metal salts to raw activated carbon or adding chemical additives to improve the activity of the metal salts. Special activated carbon. In addition, high-performance filter paper, which is another constituent material, has 99.9% removal efficiency of suspended particles ranging from 0.001㎛ to several ㎛ size, and at least 99.97% removal rate is required for 0.3㎛ size dust, which is the smallest permeable particle. .

Conventionally, a mask is used as a personal protective device to remove harmful gases and dust, but a disposable mask using a nonwoven fabric to largely remove dust, a disposable mask attached by heat-sealing activated carbon to a nonwoven fabric to remove dust and harmful gases, And it can be divided into a dust filter and a gas mask for the impregnated activated carbon filled. However, the method used so far has several disadvantages. In other words, the filter that only removes dust is difficult to remove harmful gases, and the disposable filter that removes dust and harmful gases at the same time attaches activated carbon to the nonwoven fabric, so that the pores of the activated carbon are blocked and the ability to remove harmful gases decreases at the same time. After use, it is discarded and the amount of waste increases, and the gas mask for the gas mask has a good removal ability but has a disadvantage of being expensive and bulky.

The present invention, in view of the above-mentioned drawbacks, the impregnated activated carbon having excellent adsorption power to the odor gas and also has antibacterial function and ceramics emitting far-infrared rays are filled in the filter cloth of the mask size at a constant rate and outside air flows into the filter cloth. By attaching high-performance filter paper to the site or the discharged area, a high-performance filter capable of simultaneously removing fine dust and harmful gases is prepared, and a high-performance filter is attached between the front and rear half of the general mask to manufacture a mask with a high-performance filter. In addition, instead of impregnated activated carbon to remove harmful gases, ion exchange nonwoven fabric or impregnated activated carbon fibers may be used to remove toxic gases. When wearing a mask equipped with such a high-performance filter, fine dust flowing into the human body is removed from the high-performance filter paper, while harmful gases can be removed by impregnated activated carbon, ion exchange nonwoven fabric, or impregnated activated carbon fiber filled in the high-performance filter. . In addition, since masks with high-performance filters may inhabit the activated carbon in the air, viruses or bacteria may be used in the activated carbon, so that the activated carbon containing the metal substance is added to retain the antimicrobial function on the activated carbon, and filled with ceramic powder emitting far-infrared radiation. Strengthen the function. In addition, the high performance filter removes fine dust and harmful gas, and when the service life falls, the high performance filter attached to the inside of the mask can be removed and replaced, and a new high performance filter can be installed and used again.
