Relates to a device.

In general, awareness of environmental conservation has been lacking in the course of rapid economic development, and it is well known that the pollution as well as the water quality have reached a very serious level due to the lack of such awareness. In particular, harmful gases such as sulfur dioxide, carbon dioxide, and odorous substances, including volatile organic compounds (VOCs) emitted from gas stations, the painting industry, the printing industry, and various industrial sites, are the main causes of serious air pollution. In addition, the situation is seriously adversely affecting the human body. As a result, each country has begun to sharply strengthen its institutional and policy regulations for preventing air pollution.

Recognizing the need for comprehensive conservation of the environment in the 1980s, industrial and international environmental agreements began to be signed, and more than 100 countries around the world have joined. In Korea, the average annual economic growth rate has reached 8.5% for the past 30 years, but it has achieved unbalanced growth without considering the environment by concentrating on limited strategic areas.

Environmental pollution is very serious not only domestically but also globally. It has been used for the last 20 years, including global warming and desertification due to the destruction of ozone layer, volatile organic compounds (VOC), carbon dioxide and methane generation. 15% are extinct or endangered. One of the measures proposed to solve the serious environmental pollution faced by humankind is the environmental industry.In order to quickly respond to the trends of international environmental conventions and secure competitive advantage at the national level, the development and development of environmental technology as well as environmental industry This is urgently needed.

First, when explaining the overall theory to help the understanding of activated carbon and activated carbon fiber to be described in the detailed description of the present invention is as follows. First, activated carbon (also called activated carbon) is an aggregate of amorphous carbons in which numerous micropores are well developed in one particle. The activated carbon is an adsorbent in which micropores are well formed during activation and have a large internal surface area. It is classified into Powdered Activated Carbon and Granular Activated Carbon. The raw materials of such activated carbon include sawdust, coconut oil, bituminous coal, peat, lignite and the like.

On the other hand, activated carbon fiber is made of fibrous activated carbon (activated carbon fiber) by carbonizing and activating various kinds of fibers, but it is the first to be commercialized using cellulosic fibers as a raw material. Since then, acrylonitrile (PAN) fibers and phenolic fibers have been commercialized as raw materials, and pitches have been commercialized from raw materials that have been spun by spinning and making use of the functionalities of each fiber.

Since the production of fibrous activated carbon as described above is fired or hot melted depending on the type of raw material, it is heated in an oxidizing atmosphere to prevent it from being infusible or flameproofed. This treatment also affects the performance of adsorption performance in addition to the maintenance of the shape and physical properties of the fiber after activation. Carbon fiber is obtained when carbonization is carried out by heating in an inert gas following incompatibility and flame resistance. The incompatible fiber is activated after carbonization, but in some cases, carbonization and activation may be simultaneously performed.

The above-mentioned activated carbon fiber has an average adsorption amount of 1.5 times or more than that of granular activated carbon because its adsorption capacity is very large. In addition, the adsorption rate is about 10 to 100 times that of the granular activated carbon, and because of its fibrous shape, the workability is excellent.
