(Embodiment 1)
As shown in FIGS. 1 to 5, a nonwoven fabric made of synthetic fiber made of synthetic resin not containing chlorine is pleated and an adhesive (hot melt) 1 is applied to maintain a plurality of rows at the top of the mountain. When the filter medium 2 is surrounded by an L-shaped cross section so as to be provided over the side face 3 and the ventilation end face 4 of the filter medium 2 that is fixed, the ventilation end face 4 side corresponds to the corner of the filter medium 2 and is bent. A notch 6 is provided in a portion corresponding to the corner of the filter medium 2 on the side of the frame piece 5 to be formed so as to surround the four circumferences of the filter medium 2, and both ends are joined at the side surface 3 in the pleat folding direction of the filter medium 2. A frame body 7 is provided, and the side wall 8 of the frame body 7 is formed of polypropylene, polyethylene, ABS, or the like that does not contain chlorine so that the height of the side wall 8 is smaller than the thickness dimension of the filter medium 2, and is bonded to the four circumferences of the filter medium 2. And fix.

また、枠体7の通風端面4側に設けられる枠体片5に、塩素を含まないポリエチレン、エステル系またはエーテル系ウレタンなどの合成樹脂で形成したシール材9を貼り付け、装置への組立時の密閉度を高めるようにエアフィルタ10を構成する。   Further, a seal member 9 formed of synthetic resin such as polyethylene, ester-based or ether-based urethane not containing chlorine is attached to the frame piece 5 provided on the side of the ventilation end surface 4 of the frame 7 to assemble the apparatus. The air filter 10 is configured to increase the degree of sealing.

上記構成において、図2に示すように空気調和機の空気流路にエアフィルタ10がプレフィルタ10aと共に取付レール25に沿って組み込まれるときには、枠体7は紙に比べて強度も高く、寸法精度も安定しているので組み込み易く、また送風運転による風圧の作用でシール材9が空気調和機の装着部に密着するため空気流路からの空気漏れがなくなる。   In the above configuration, as shown in FIG. 2, when the air filter 10 is incorporated in the air flow path of the air conditioner along with the mounting rail 25 together with the pre-filter 10a, the frame body 7 has higher strength than paper and has dimensional accuracy. Since the sealing member 9 is in close contact with the mounting portion of the air conditioner by the action of the wind pressure by the air blowing operation, air leakage from the air flow path is eliminated.

次に、塵埃がエアフィルタ10上に堆積してエアフィルタ10を交換する必要が生じたときには、エアフィルタ10を取付レール25から引き出して、そのままの形で廃棄物燃料の製造工場に引渡すことにより廃棄物再生燃料に再生されることとなる。   Next, when dust accumulates on the air filter 10 and the air filter 10 needs to be replaced, the air filter 10 is pulled out from the mounting rail 25 and delivered to the waste fuel manufacturing factory as it is. It will be recycled to waste regenerated fuel.

このように廃棄物再生燃料に再生される廃棄物燃料製造とは、いわゆるRDF(廃棄物固形化燃料)製造、廃プラスチック油化等をいい、廃棄物発電や廃棄物熱処理用のために行われるものであって、RDFは燃えるごみを集めて細かく砕き、乾燥させ、添加物を加えて圧縮することにより作られるもので、RDFの熱量は石炭の約半分を有し、燃焼も安定しており、また、腐らない、悪臭が出ない、保存可能、ハンドリングが容易、単純焼却より高い燃焼温度が得られ、燃やしたときにダイオキシン等の有害物をほとんど発生せず、多くの長所を有している。   In this way, the production of waste fuel that is recycled into waste regenerated fuel refers to so-called RDF (waste solidified fuel) production, waste plastic oil production, etc., and is performed for waste power generation or waste heat treatment. RDF is made by collecting burning garbage, pulverizing it, drying it, adding additives and compressing it. The heat of RDF is about half that of coal, and combustion is stable. In addition, it does not rot, does not emit bad odor, can be stored, is easy to handle, has a higher combustion temperature than simple incineration, has almost no harmful substances such as dioxin when burned, and has many advantages Yes.

この実施形態1では、エアフィルタ10を塩素を含まない合成樹脂に統一してダイオキシンを生じないだけでなく、紙や布を含まないので、均質燃料として燃焼時・保管時の保守管理も容易に行うことができる。   In the first embodiment, the air filter 10 is unified with a synthetic resin not containing chlorine so that dioxins are not generated, and since paper and cloth are not included, maintenance management during combustion and storage as a homogeneous fuel is easy. It can be carried out.

また、実施の形態1では枠体7を断面L字形の帯状の部材を折り曲げ、濾材2を囲み固定することとしたが、図4に示すように、断面がL字状で枠体片5aの両端に傾斜面11を形成した横側枠体単片12と縦側枠体単片13を傾斜面11を有する角部で接合して枠体7aを形成しても同様の作用効果をもたらすものである。   In the first embodiment, the frame 7 is formed by bending a band-shaped member having an L-shaped cross section to surround and fix the filter medium 2. However, as shown in FIG. Even if the frame 7a is formed by joining the horizontal frame single piece 12 having the inclined surfaces 11 formed at both ends and the vertical frame single piece 13 at the corners having the inclined surfaces 11, the same effect can be obtained. It is.

また、図5に示すように、断面L字状の横側枠体単片12と縦側枠体単片13を一体とした枠体単体14を一対設け、角部をL形接合片15で接合して枠体7bを形成しても同様の作用効果をもたらすものである。   Further, as shown in FIG. 5, a pair of frame units 14 each having a lateral frame unit piece 12 having a L-shaped cross section and a vertical frame unit piece 13 are integrally provided, and corner portions are formed by L-shaped joining pieces 15. Even if it joins and forms frame 7b, it brings about the same operation effect.
