Description

Apparatus for manufacturing activated carbon filter having a multilayer structure

The present invention relates to an activated carbon filter having a multilayered structure, an activated carbon filter manufacturing apparatus having a multilayered structure, and a method of manufacturing a multilayered activated carbon filter using the same. More particularly, a multilayered structure capable of purifying both an acid gas and a basic gas can be provided. The present invention provides an activated carbon filter having an activated carbon filter, an apparatus for manufacturing an activated carbon filter having a multilayer structure, and a method of manufacturing an activated carbon filter having a multilayer structure using the same.

In general, activated carbon filters have a function of filtering automobile exhaust gases present in the atmosphere or various gases and dusts generated in various industries.

Accordingly, the activated carbon filter is widely used not only for the industrial purification of automobile exhaust gas and various gases generated in various industries, but also for domestic use such as air purifiers and automobile air purification filters.

Activated charcoal filters are used for adsorption of nonpolar hydrocarbons such as benzene and toluene, but deodorants containing an acid and alkali metal halide mixture are not used because of insufficient odor gas including ammonia.

The support of the acid and alkali metal halide mixture on the activated carbon is presented in Korean Patent No. 33545, "Air Purifying Deodorant."

However, when the surface containing the micropores of the activated carbon is impregnated with an acid and an alkali metal halide, van der Waals forces are weakened, so that a large amount of ammonia can be adsorbed compared to general activated carbon.

When ammonia or the like is adsorbed on the surface of activated carbon, activated carbon is saturated with ammonia, which is used as an energy source for microorganisms. Ammonia has a problem in that it acts as a source of odor by performing an electron donor role of the nitric oxide and synthesizing sulfur oxides when the oxygen concentration in the micropores is accompanied by anaerobic reaction.

In addition, the activated carbon filter frequently occurs when the activated carbon powder located in the nonwoven fabric falls off the nonwoven fabric, thereby degrading the performance of the filter and generating activated carbon dust around.

In order to solve this problem, there is a problem in that the activated carbon powder is adhered to and fixed in the nonwoven fabric using an adhesive. In this case, the manufacturing cost is increased and an odor due to the chemical component of the adhesive is generated.
