産業上の利用分野
本発明は、空気清浄機や脱臭機の脱臭フィルターとして
用いる薬品添着ハニカム型活性炭及びその製造方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a honeycomb-type activated carbon impregnated with chemicals used as a deodorizing filter for air purifiers and deodorizing machines, and a method for producing the same.

同じ石炭やヤシガラ等を用いている。BACKGROUND OF THE INVENTION Conventionally, honeycomb-type activated carbon has been characterized in that it has a smaller pressure loss than ordinary crushed and granulated activated carbon, and because it is formed into fine particles, it has excellent deodorizing performance. The raw materials for this honeycomb-type activated carbon include the same coal and coconut husks that are used for regular activated carbon.

。Problems to be Solved by the Invention Therefore, although such conventional honeycomb-type activated carbon can sufficiently exhibit the deodorizing performance inherent to activated carbon, it cannot deodorize ammonia, hydrogen sulfide, aldehydes, etc. that cannot be deodorized even with activated carbon. It had some problems.
また、ハニカム構造を、前記のとおりに川かい粒子で成

であって孔径が小さいもの（ミクロボアー）が非常に多
くなっているため、一度吸著した成分を温度、湿度等の

。In addition, because the honeycomb structure is formed from river particles as mentioned above, the pores are uniform and have a large number of small pores (microbore) compared to ordinary activated carbon. However, there is a problem in that the components once absorbed are likely to be re-released due to external influences such as temperature and humidity.
本発明は上記の問題点に鑑み、ハニカム型活性炭の使用

である。In view of the above-mentioned problems, the present invention provides a chemical-impregnated honeycomb-type activated carbon that has excellent deodorizing performance and prevents re-release by impregnating a special chemical to the honeycomb-type activated carbon. The purpose is to provide the following.

して構成されたものである。Means to Solve the Problem In order to solve this problem, the uninvented chemical-impregnated honeycomb activated carbon is a honeycomb activated carbon formed into fine cells that is deodorized by activated carbon such as ammonia, hydrogen sulfide, or aldehyde. It is constructed by attaching a chemical that chemically adsorbs.

を構成したものである。The present invention also provides that, in order to produce the honeycomb-type activated carbon impregnated with a chemical as described above, the honeycomb-type activated carbon formed into fine cells is immersed in a bath containing the chemical for chemical adsorption, and then impregnated with the honeycomb-type activated carbon. This method consists of firing and drying.

A chemical reaction occurs between the chemicals attached to the surface, and deodorization occurs through chemical adsorption.

In the figure, the chemical-impregnated honeycomb-type activated carbon (1) is honeycomb-type activated carbon impregnated with acidic, alkaline IJ Ii, or weakly acidic chemicals depending on the odor component, and it looks like normal honeycomb-type activated carbon. Almost no change. In this chemical-impregnated honeycomb activated carbon (1), the surface (la) through which air passes is practically 10 to 1000 meshes (10 to 1000 cells/M
) is molded into fine cells to minimize air resistance.

I will explain about it. Chemical-impregnated honeycomb-type activated carbon (IJ) is composed of fine cells, so its
The finer the particles or the greater the thickness, the longer the contact time with odor components and the better the deodorizing performance. Among the odor components such as ammonia, hydrogen sulfide, and aldehydes, in which activated carbon alone has a weak deodorizing effect, in an odor environment that contains a large amount of ammonia, honeycomb-type activated carbon impregnated with acidic chemicals such as sulfuric acid and organic acids can be used to remove odors. Effective chemisorption of ammonia occurs, greatly improving deodorizing performance. Furthermore, in an odor environment containing a large amount of acidic odor components such as hydrogen sulfide, the deodorizing performance is greatly improved by using honeycomb-type activated carbon impregnated with an alkali group chemical such as sodium hydroxide. In addition, in an odor environment that contains many alkaline and acidic odor components, honeycomb-type activated carbon impregnated with a chemical such as iron halide that is weakly acidic and causes a chemical reaction with sulfides can be used to remove alkaline odor. It can chemically adsorb both acidic and acidic odors. Regarding aldehydes, the deodorizing performance can be similarly improved by impregnating them with chemicals that chemically adsorb them.
また、上記のような化学吸着を行わせることにより、物

やすい臭気成分でも、再放出を防止することができる。Further, by performing chemical adsorption as described above, it is possible to prevent the re-release of odor components that are likely to be re-released due to external influences such as temperature and humidity by physical adsorption alone.

First, prepare the honeycomb-type activated carbon (1) (Figure 2 a), decide on the chemical to be impregnated with according to the target odor component, and place the determined chemical in a tank adjusted to a certain concentration. Honeycomb-shaped activated carbon is immersed in the water for a certain period of time (Figure 2b). The honeycomb activated carbon that has been soaked and stored with chemicals is placed in a firing furnace and fired and dried at a constant temperature for a certain period of time (Fig. 2C).

By chemically adsorbing odor components such as odors and preventing their re-emission, a great practical effect of significantly improving deodorizing performance can be obtained.
