Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は吸着フィルターに関する。[Detailed description of the invention] [Industrial application field] This invention relates to an adsorption filter.
従来、吸着フィルター用の吸着材として、活性炭を用い
たものがよく知られている。ところが、活性炭は、例え
ば、アンモニアのような低分子ガスに対しては十分な吸
着作用がない。Conventionally, activated carbon is well known as an adsorbent for adsorption filters. However, activated carbon does not have a sufficient adsorption effect on low molecular gases such as ammonia.
一方、吸着フィルターは、例えば、一般家庭における空
気清浄に用いられる。吸着が進んで吸着材が飽和状態に
達すると、吸着作用は停止する。On the other hand, adsorption filters are used, for example, for air purification in general households. When the adsorption progresses and the adsorbent reaches a saturated state, the adsorption action stops.
吸着作用を回復させるために、新たな吸着材と交換する
。しかし、新たな吸着材と交換していたのでは、その都
度、高価についてしまうだけでなく、手間もかかる。Replace with new adsorbent to restore adsorption effect. However, replacing the adsorbent with a new one each time is not only expensive but also time-consuming.
アンモニアのような低分子ガスが吸着できないと、利用
範囲が大幅に制限される。また、吸着作用の回復にコス
トがかかったり、手間がかかっていては、汎用性がなく
なり、やはり利用範囲が限られることになる。If low-molecular gases such as ammonia cannot be adsorbed, the range of use will be greatly limited. Furthermore, if recovery of the adsorption effect is costly or time-consuming, the product will lack versatility and its range of use will be limited.
この発明は、このような事情に鑑み、アンモニアのよう
な低分子ガスを十分に吸着することができ、吸着作用回
復が高くついたり、手間がかかったりしない吸着フィル
タを提供することを目的とする。In view of these circumstances, it is an object of the present invention to provide an adsorption filter that can sufficiently adsorb low-molecular gases such as ammonia, and does not require high cost or effort to recover the adsorption action. .
前記課題を解決するため、この発明にかかる吸着フィル
ターは、無機層状多孔質粒子からなる吸着材と同吸着材

分解させる金属触媒を含んでいる。In order to solve the above problems, an adsorption filter according to the present invention includes an adsorbent made of inorganic layered porous particles and a heater that heats the adsorbent, so that the adsorbent is regenerated by heating. Additionally, the adsorbent contains a metal catalyst that decomposes the adsorbate.
請求項1.2記載の発明においては、吸着材が無機層状
多孔質粒子からなるために、アンモニアのような低分子

以下、この発明にかかる吸着フィルターを、その一実施
例をあられす図面を参照しながら詳しく説明する。In the invention described in claim 1.2, since the adsorbent is made of inorganic layered porous particles, it can sufficiently adsorb even a low molecular gas such as ammonia, and moreover, it can be adsorbed simply by operating the heater to heat the adsorbent. Furthermore, in the second aspect of the invention, the metal catalyst contained in the adsorbent decomposes the adsorbent. For example, adsorbed substances that emit bad odors are decomposed into odorless substances or decomposed into non-adsorbed substances, thereby deodorizing and suppressing the saturation of adsorption. An embodiment of the filter will be described in detail with reference to the accompanying drawings.
第1図は、この発明の吸着フィルターの一実施例の概略
構成をあられす。FIG. 1 shows a schematic configuration of an embodiment of an adsorption filter of the present invention.
吸着フィルター1は、2枚の吸着材2.2を備え、両吸

つに組み付けられている。The adsorption filter 1 includes two sheets of adsorbent 2.2, and an electric heater 3 for heating the adsorbent between both adsorbents 2.2. A ceramic wool (ceramic fiber) layer 4.4 is provided between the adsorbent 2.2 and the electric heater 3. The ceramic wool layer 4.4 is provided to fill the gap between the adsorbent 2 and the electric heater 3. Each of these villages is assembled into one by wrapping a metal wire (not shown) around the outside.
吸着材2は、前記のように、無機層状多孔質粒子からな

多数有していて、比表面積が、例えば、600rrf/
g程度もあり、アンモニア(ガス)等の低分子ガスでも
十分に吸着する。無機質からなるため、耐熱性も、例え
ば、600℃と非常に高い。As mentioned above, the adsorbent 2 is made of inorganic layered porous particles, has many pores of several tens to hundreds of pores between the eyebrows of the particles and between the particles, and has a specific surface area of, for example, 600rrf. /
It can sufficiently adsorb even low-molecular gases such as ammonia (gas). Since it is made of inorganic material, its heat resistance is also very high, for example, 600°C.
無機層状多孔質粒子としては、例えば、スメクタイト型
鉱物(モンモリロナイト、ペンナイト、緑泥石、バイデ
ライト、ヘクトライト、合成マイカ、テニオライト等)

、A11s Ox 、ZrO*、Ge0t 、Few
O□等)や炭素塊等が挿入されて眉間に空隙が維持され

For example, inorganic substances (S fox, Tl0i
, A11s Ox , ZrO*, Ge0t , Few
There are some compounds (intercalation compounds) in which a gap is maintained between the eyebrows by inserting a carbon block or the like (O□, etc.) and a porous structure.

に阻止できる。Some adsorbents 2 have pore size distributions that have two peaks: minute dimensions in the range of tens to hundreds of micrometers and small dimensions in the range of several μm to several hundred μm. . This adsorbent 2 mainly adsorbs low-molecular gas and the like through minute pores, while adsorbing (filtering) dust and the like through small pores. Therefore, it is possible to effectively prevent dust and the like from blocking the microscopic pores and reducing the adsorption effect of low-molecular gases and the like.

It is also effective to include metal catalysts such as metal oxides or metal salts to decompose harmful adsorbed substances into harmless substances (for example, decompose malodorous substances into odorless substances). It is. If the adsorption state is released by decomposition, adsorption saturation can be prevented, which is even more effective.

Examples of catalysts include, but are not limited to, metals such as silver, copper, manganese, iron, cobalt, nickel, zinc, chromium, platinum, palladium, molybdenum, vanadium, oxides of these metals, and salts of these metals. Specific examples are listed.
電気ヒータ3としては、セラミックヒータ(P
−TCヒータ)やニクロム線ヒータが用いられる。As the electric heater 3, a ceramic heater (P

費用も、加熱用の電気代だけであるから安いものである
。具体的な電気ヒータ3としては、例えば、セラミック
ヒータ(TOTO製 サウナ用ヒータ)がある。When the adsorption reaches saturation, the electric heater 3 is activated to raise the temperature to 200° C., for example, to burn and remove the adsorbate, thereby restoring the adsorption effect. In other words, the adsorbent 2 is regenerated. This is an extremely simple task since it is just a matter of turning on the electric heater 3. As mentioned above, since it is inorganic and has heat resistance, there is no fear of deterioration even if such adsorption recovery treatment by heating is performed. The cost of regeneration is also low because it only costs electricity for heating. A specific example of the electric heater 3 is a ceramic heater (TOTO sauna heater).
ガラスウール層4には、例えば、セラミックファイバー
(新日鐵化学株式会社製 ニスファイバーSCバルク状
)が用いられる。For the glass wool layer 4, for example, ceramic fiber (varnished fiber SC bulk type manufactured by Nippon Steel Chemical Co., Ltd.) is used.

Add titania sol and allow sufficient insertion reaction at about 60°C. This silica-titania sol was prepared as follows. After mixing ethyl silicate (Hani Kagaku ■t), which is one of the total alkoxides, with ethyl alcohol, it is hydrolyzed with hydrochloric acid, and a hydrochloric acid peptizer of titanate propoxide is added to this. However, silica: titania = 10 :1 (mo/ratio).

材を作ってもよい。When freeze-dried, small-sized pores are formed in the inorganic layered porous particles themselves, and relatively large-sized pores are formed between the particles, resulting in the pore size distribution as explained above. It is also possible to create an adsorbent that has peaks in two dimensions. After freeze-drying, the adsorbent may be further calcined to produce the adsorbent.
