A manufacturing method of filter composite for removal of volatile organic compounds Co2 reduction is possible and filter having the filter composite manufactured by the same}

The present invention relates to a method of manufacturing a filter composite for removing volatile organic compounds capable of reducing Co2, which can provide a filter composite having excellent removal efficiency of volatile organic compounds and improved lifespan, and a filter including the filter composite.

VOLATILE ORGANIC COMPOUND (VOC) is a generic term for organic substances that can be volatilized into the air.These volatile organic compounds contain various organic solvents or organic compounds such as benzene, toluene, styrene, xylene, ethylbenzene, acetylaldehyde, etc. Can be included.

These volatile organic compounds are easily evaporated into the atmosphere due to their high vapor pressure, and when they coexist with nitrogen oxides in the atmosphere, they cause photochemical reactions under the action of sunlight to generate photochemical oxidizing substances such as ozone and PAN, thereby causing photochemical smog, which is even greater in the environment. It can have adverse effects. In addition, since these volatile organic compounds contain many carcinogenic substances and are substances that cause air pollution and global warming, they have a high impact on the human body and ecosystem and are classified as specific atmospheric hazardous substances to reduce their emissions by country, It is managed by policy. However, since the volatile organic compound (VOC) gas exists in a gaseous state, it is very difficult to manage it.

As a filter for purifying air by effectively adsorbing and removing such volatile organic compounds, a filter using activated carbon is currently the most widely used filter. Activated carbon is widely used in various fields, such as air conditioners and deodorants in industrial sites, as well as homes, because of its excellent far-infrared radiation effect and excellent adsorption rate of various foreign substances due to its carbonized internal mesh structure.

More specifically, Korean Patent Registration No. 10-0550517 discloses an air purification device that removes dust and odors generated in various industrial facilities, restaurants, and homes by manufacturing a filter filled with activated carbon fibers, and Korean Patent No. 10 No. -1483263 discloses a filter having excellent volatile organic compound removal performance and lifetime by manufacturing an activated carbon molded body surface-modified with an ocher filtrate.

However, since dust formed during the manufacturing process remains in the internal pores of these activated carbon filters, the efficiency of removing volatile organic compounds is lowered, and the manufacturing process of modifying the surface to improve this is complicated, and the material used for surface modification is rather environmental There is a problem that contaminates the situation. In addition, when the internal pores are saturated with contaminants, it no longer functions as a filter, so it is essential to periodically replace it with new activated carbon. Therefore, it is necessary to improve the life of such activated carbon from an economical or environmental aspect.

There is an effect. In particular, as the volatile organic compound, it has excellent removal efficiency for benzene, toluene, styrene, xylene, and acetylaldehyde, and has an effect of greatly improving lifespan.

Hereinafter, a method of manufacturing a filter composite for removing volatile organic compounds capable of reducing Co2 according to an embodiment of the present invention will be described in more detail.

First, in the granular activated carbon preparation step, granular activated carbon capable of imparting excellent ventilation properties and strength to the filter composite for removing volatile organic compounds according to an embodiment of the present invention is prepared.

These granular activated carbons have an average particle size of 20 to 50 mesh and a specific surface area of 500 to 1500 m ² /g measured by the BET method is used to remove volatile organic compounds according to an embodiment of the present invention. There is an effect of imparting more excellent ventilation and strength to the filter composite for use.

In addition, since the granular activated carbon has an iodine adsorption capacity of 1000 mg/g or more according to the KS M 1802 standard, not only the above effects but also the efficiency of removing volatile organic compounds can be further improved.

Thereafter, in the ultrapure water washing step, the prepared granular activated carbon is washed using ultrapure water of 18 MΩ·cm or more. Thereby, there is an effect of removing dust remaining in the internal pores of the prepared granular activated carbon. In addition, by expanding the internal pores, there is an effect of further improving the efficiency of removing volatile organic compounds. In addition, there is an effect of improving the fine dust removal performance.

It can be carried out using the granular activated carbon washing apparatus 10 comprising a.

In addition, the granular activated carbon washing apparatus 10 includes an ultrafiltration membrane unit 12 for purifying by removing particulates and microorganisms contained in raw water; And including the ion exchange resin part 13 for precisely removing cations, anions, or all of them contained in the purified water, the ultrapure water production unit and the granular activated carbon washing unit may be integrally configured. As a result, washing can be performed while flowing ultrapure water of 18 MΩ·cm or more, which has been purified from raw water, to the prepared granular activated carbon. The internal configuration diagram of the granular activated carbon washing apparatus used in one embodiment of the present invention is shown in FIG. 2. However, the granular activated carbon washing apparatus is provided as an example, and the present invention is not limited thereto.

<Production Example>

As the granular activated carbon, one having an average particle size of 50 mesh and a specific surface area of 876 m ² /g measured by the BET method was used. In addition, the granular activated carbon was prepared having an iodine adsorption capacity of 1025 mg/g according to the KS M 1802 standard.

In the granular activated carbon washing apparatus shown in FIG. 2, after loading the prepared granular activated carbon, ultrapure water of 18 MΩ·cm or more prepared by being purified from raw water was immediately flowed into the prepared granular activated carbon, and ultrapure water washing was performed for 3 hours.

The granular activated carbon having been washed with ultrapure water was dried at about 25° C. for 5 hours to prepare the dried granular activated carbon.

<Comparative Manufacturing Example>

That is, by performing the ultrapure water washing step and the drying step on the prepared granular activated carbon, it was confirmed that the particulate activated carbon's own fine dust removal performance was improved.

It is believed that this is due to the improvement in the self-performance of the granular activated carbon by removing dust remaining in the internal pores of the granular activated carbon and expanding the internal pores through the ultrapure water washing and drying steps.
