【考案の詳細な説明】 （産業上の利用分野） 本考案は、気体脱臭，清浄用フイルターに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a gas deodorizing and cleaning filter.
（従来の技術） アンモニア、トリメチルアミン、硫化水素、メルカプタ
ン系等の悪臭の脱臭用素材として従来から活性炭が主流
として用いられている。この活性炭は粒状あるいは粉状
であるが、これには極微粒子がかなり含まれているた

と目詰まりを起こす原因となり、また脱湿効果が少な
い。(Prior Art) Activated carbon has been mainly used as a material for deodorizing bad odors such as ammonia, trimethylamine, hydrogen sulfide, and mercaptans. This activated carbon is in the form of particles or powder, but since it contains a very large amount of ultrafine particles, it causes clogging when used as a filter element of an air purifier, and has a low dehumidifying effect.

ブロック形状に形成したエレメントをフイルターとして
清浄機に充填して用いられている。Therefore, recently, porous glass fibers made of a compatible glass such as borosilicate sodium glass having a high SiO 2 content as a raw material have been used instead of the activated carbon element. At this time, the porous glass fiber is usually formed into a paper shape and is formed into a corrugated cardboard shape consisting of a smooth sheet and a corrugated sheet to obtain a material, and the material is further wound into a spiral shape to form a block-shaped element as a filter. It is used by filling it in a purifier.

揮させることができないという問題がある。(Problems to be solved by the invention) However, the porous glass fiber has a small pore size and
There are various ET surface areas and various pore volumes, and none of them have a deodorizing effect. On the other hand, since the flow passage group of the element is provided in parallel with the axis, the fluid passes straight through the flow passage and the adsorption efficiency is poor. Therefore, in order to improve this, it is conceivable to increase the axial length and diameter of the element or increase the density of the flow passage group, but there are restrictions on the capacity of the air cleaner, the velocity of the fluid, the concentration, etc. Therefore, there is a problem that the adsorption performance of the element material cannot be fully exhibited.
本考案は脱臭と脱湿効果が優れ、且つ吸着性能の優れた
気体脱臭、清浄用フイルターを提供することを目的とす

用した。(Means for Solving the Problem) As a means for achieving the above object, the present invention is an element in which a corrugated cardboard-like material composed of a smooth sheet and a corrugated sheet is formed in a block shape as a spiral shape or a laminated shape. The flow passage group formed by the both sheets is provided so as to intersect the axis of the element, and the corrugated sheet or both sheets is a porous glass paper obtained by mixing porous glass fibers and fibrillated organic binder fibers. The following configuration was adopted.

が損なわれない。(Function) The element which is the filter of the present invention is used by filling it in the air cleaner. When basic gas such as ammonia gas or air containing cigarette smoke was passed through the purifier, the porous glass fibers in the element favorably adsorbed the basic gas and nicotine in cigarette smoke. And gas,
When the adsorption performance of smoke or the like is deteriorated, the element is taken out from the cleaner, and after removing dust, the adsorbed gas, moisture, etc. are separated and regenerated by appropriately heating the element to about 180 ° C. by a heating means. At this time, especially when the binder fiber of the porous glass paper is a heat-resistant organic fiber, the performance of the element is maintained despite the heating, and the heat-resistant organic fiber is not thermally affected, and the porous glass The function of the fiber as a binder is not impaired.

It has become longer and the adsorption performance has improved accordingly.
