Description

本発明は、工場の設備で黒煙は発生したとき消煙する黒煙消煙装置に関し、詳しくは黒煙発生源で瞬時に多量の黒煙を発生する際に使用する黒煙消煙装置に関するものである。   The present invention relates to a black smoke extinguishing device that extinguishes when black smoke is generated in a factory facility, and more particularly to a black smoke extinguishing device used when a large amount of black smoke is instantaneously generated at a black smoke generating source. Is.

従来、工場の設備で黒煙等が発生した場合に消煙する消煙装置としては排気を所定温度（例えば７５０〜８００℃）に加熱し、一定時間（０．３〜１秒）滞留させて消煙する直燃式消煙装置が良く用いられる。焼却炉の分野では排気を加熱して消煙するものとしては例えば特許文献１や特許文献２ある。また排気経路に触媒を設けると共にこの触媒を加熱するヒータを設けることにより触媒にて消煙する方式（例えば、特許文献３参照）のものもある。
特開平１０−２６７２５４号公報 特開平８−２４５７５号公報 特開平１０−２６７２５４号公報 Conventionally, as a smoke extinguishing device that extinguishes smoke when black smoke or the like is generated in a factory facility, the exhaust is heated to a predetermined temperature (for example, 750 to 800 ° C.) and held for a certain time (0.3 to 1 second). A direct-fire type smoke eliminator that extinguishes smoke is often used. In the field of incinerators, there are, for example, Patent Document 1 and Patent Document 2 as examples of heating and exhausting exhaust gas.

ところで、熱処理工場等で焼き入れ時に油槽から発生する黒煙は発生時間が短い（例えば３０秒程度）ものの一度に多量に発生し、環境対策が切望されている。しかしながら上記従来例の前者のような消煙装置では短時間に多量に発生する黒煙を消煙するためには排気を加熱するための加熱装置の容量が極めて大きくなり、設備が大型になると共に極端な投資を必要とする。また上記のような熱処理工場で焼き入れにより黒煙が発生するのは１日１回程度であり、一時的に多量に発生する黒煙を処理するための上記のような設備投資をするのは設備的に無駄が多い。このため、消煙装置の導入が進んでおらず、環境対策が困難になっている。また上記従来例の後者のように触媒を用いるものも前者と同様に設備が大型になるという問題がある。   By the way, although black smoke generated from an oil tank at the time of quenching in a heat treatment factory or the like is short in generation time (for example, about 30 seconds), it is generated in large quantities at once, and environmental measures are desired. However, in the smoke eliminator like the former of the above-mentioned conventional example, the capacity of the heating device for heating the exhaust gas becomes extremely large in order to extinguish a large amount of black smoke generated in a short time, and the equipment becomes large. Requires extreme investment. Moreover, black smoke is generated only once a day by quenching in the heat treatment plant as described above, and the above-mentioned capital investment for treating black smoke generated in large quantities temporarily is necessary. There is a lot of waste in terms of equipment. For this reason, the introduction of smoke eliminating devices has not progressed, and environmental measures have become difficult. Also, the latter using the catalyst as in the latter case of the conventional example has a problem that the equipment becomes large as in the former case.

本発明は上記の従来の問題点に鑑みて発明したものであって、瞬時に多量に黒煙が発生しても黒煙を除去することができるものでありながら設備が大型にならないと共に設備投資を低減でき、環境対策に貢献できる黒煙消煙装置を提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned conventional problems, and even if black smoke is instantaneously generated in large quantities, it is possible to remove the black smoke, but the equipment does not become large in size and is capital investment. It is an object of the present invention to provide a black smoke extinguishing device that can reduce environmental impact and contribute to environmental measures.

上記課題を解決するために本発明の請求項１の黒煙消煙装置は、工場の黒煙発生源１の近傍に設置される消煙装置本体２と、消煙装置本体２内に黒煙発生源１から黒煙を吸い込む吸い込み口３と、消煙装置本体２内から屋外に排気する排気筒４と、吸い込み口３から吸い込んで排気筒４から排気するように送風する送風ファン５を具備した黒煙消煙装置であって、吸い込み口３から吸い込んだ黒煙の煤を捕捉するための耐熱性のあるフィルターＡを消煙装置本体２内に設けると共にフィルターＡに捕捉した黒煙の煤を焼失させるためにフィルターＡを加熱するフィルター加熱手段Ｂを設けたことを特徴とする。   In order to solve the above-described problems, a black smoke eliminator according to claim 1 of the present invention includes a smoke eliminator body 2 installed in the vicinity of a black smoke generation source 1 in a factory, and black smoke in the smoke eliminator body 2. A suction port 3 for sucking black smoke from the generation source 1, an exhaust cylinder 4 for exhausting the smoke from the smoke eliminator main body 2 to the outdoors, and a blower fan 5 for sucking air from the suction port 3 so as to exhaust from the exhaust cylinder 4 are provided. The black smoke smoke eliminator is provided with a heat-resistant filter A in the smoke eliminator body 2 for capturing the black smoke smoke sucked from the suction port 3 and the black smoke smoke trapped in the filter A. A filter heating means B for heating the filter A is provided in order to burn off the filter.

上記構成によれば、黒煙発生源１で黒煙が発生するとき、送風ファン５を駆動することで黒煙発生源１から発生した黒煙を吸い込み口３から吸い込んでフィルターＡに黒煙の煤を捕集し、浄化した空気を排気筒４から排出できる。また黒煙発生源１で黒煙が発生しない間にフィルター加熱手段ＢでフィルターＡを加熱することでフィルターＡに捕集した黒煙の煤を焼却除去することができる。このようにすることで黒煙発生部１で瞬時に多量の黒煙が発生してもフィルターＡで捕集して空気を浄化することができると共に黒煙を発生しない間にフィルターＡに捕集した黒煙の煤を焼却除去できるために時間をかけて加熱して処理することができる。従って瞬時に多量に黒煙が発生しても黒煙を除去することができるものでありながら従来のように設備が大型にならないと共に設備投資を低減でき、環境対策に貢献できる。   According to the above configuration, when black smoke is generated at the black smoke generation source 1, the blower fan 5 is driven to suck the black smoke generated from the black smoke generation source 1 through the suction port 3 and The soot is collected and the purified air can be discharged from the exhaust tube 4. Further, the black smoke trapped in the filter A can be incinerated and removed by heating the filter A with the filter heating means B while the black smoke generation source 1 does not generate black smoke. By doing so, even if a large amount of black smoke is instantaneously generated in the black smoke generating section 1, it can be collected by the filter A to purify the air, and also collected in the filter A while no black smoke is generated. Since the smoked black smoke can be removed by incineration, it can be heated and treated over time. Accordingly, even if a large amount of black smoke is instantaneously generated, the black smoke can be removed, but the equipment is not increased in size as in the prior art, and the equipment investment can be reduced, contributing to environmental measures.

また本発明の請求項２の黒煙消煙装置は、工場の黒煙発生源１の近傍に設置される消煙装置本体２と、消煙装置本体２内に黒煙発生源１から黒煙を吸い込む吸い込み口３と、消煙装置本体２内から屋外に排気する排気筒４と、吸い込み口３から吸い込んで排気筒４から排気するように送風する送風ファン５とを具備した黒煙消煙装置であって、フィルターＡは周囲にフィルター面を設けた筒状のフィルター部材６で構成し、消煙装置本体２内の空間を吸い込み側である下部空間７と排気側である上部空間８とに仕切る仕切りに複数個のフィルター部材６をフィルター部材６が下部空間７内に並ぶように吊り下げ、下部空間７内から各フィルター部材６の周囲のフィルター面、フィルター部材６内を介して上部空間８内に空気が流れるようにしたことを特徴とする。   Further, the black smoke eliminating apparatus according to claim 2 of the present invention includes a smoke eliminating apparatus main body 2 installed in the vicinity of the black smoke generating source 1 in the factory, and the black smoke from the black smoke generating source 1 in the smoke eliminating apparatus main body 2.

The soot is collected and the purified air can be discharged from the exhaust tube 4. When removing the black smoke, the black smoke soot is collected on the filter surface of the filter member 6 from the lower space 7 through the filter surface around the cylindrical filter member 6, the filter member 6, and the upper space 8. Therefore, black smoke soot is collected on the filter surface of a very large area. As a result, even if a large amount of black smoke is generated instantaneously, the smoke of black smoke can be reliably collected without increasing the air ventilation resistance. By providing the cylindrical filter member 6 in this way, black smoke soot can be collected, so that black smoke can be removed even if a large amount of black smoke is instantaneously generated, as in the conventional case. Equipment can be reduced in size and capital investment can be reduced, contributing to environmental measures.

When burned in the burner body 10a, the combustion exhaust gas passes through the combustion cylinder 10b, and the combustion exhaust gas is discharged from the through hole 10c of the combustion cylinder 10b. It has become. When the gas burner 10 is provided in the lower space 7, in this example, the combustion cylinder 10 b is mounted below the soot 21 so as to extend along the entire length of the soot 21.

上記のように黒煙消煙装置が構成され、次のように使用される。黒煙発生源１で黒煙が発生するとき、ダンパー１３を開放した後送風ファン５が駆動される（送風ファン５が駆動されると共にダンパー１３が開放されてもよい。）。すると、黒煙が吸い込み口３から吸い込まれ、フィルターＡとしてのフィルター部材６に黒煙の煤が捕集され、浄化された空気が排気筒４から排気される。黒煙を除去するとき、下部空間７から、フィルター部材６のフィルター面としてのセラミックファイバーブランケット９、フィルター部材６内、上部空間８を通り、フィルター面としてのセラミックファイバーブランケット９に捕集されるため極めて広い面積のフィルター面に黒煙の煤が捕集される。これにより瞬時に多量の黒煙が発生しても空気の通気抵抗が増加したりすることなく黒煙の煤を確実に捕集できる。またセラミックファイバーブランケット９を用いているため目が細かくて黒煙の煤を確実に捕集できると共に目詰まりしにくい。   The black smoke extinguishing device is configured as described above and used as follows. When black smoke is generated at the black smoke generation source 1, the blower fan 5 is driven after opening the damper 13 (the blower fan 5 may be driven and the damper 13 may be opened). Then, black smoke is sucked from the suction port 3, black smoke soot is collected by the filter member 6 as the filter A, and the purified air is exhausted from the exhaust tube 4. When removing black smoke, the ceramic fiber blanket 9 as the filter surface of the filter member 6, the filter member 6, and the upper space 8 are collected from the lower space 7 to be collected by the ceramic fiber blanket 9 as the filter surface. Black smoke traps are collected on a very large filter surface. As a result, even if a large amount of black smoke is generated instantaneously, the smoke of black smoke can be reliably collected without increasing the air ventilation resistance. Moreover, since the ceramic fiber blanket 9 is used, the eyes are fine, so that black smoke soot can be reliably collected and clogging is difficult.

上記のように黒煙の煤をフィルター部材６で捕集することができるが、フィルター部材６に黒煙の煤が溜まると、定期的に黒煙の煤を除去してフィルター部材６を再生する必要がある。このため、黒煙発生源１で黒煙を発生しないとき、ダンパー１３を閉止した後（フィルターＡ再生時には閉めて置く必要がある。）フィルター加熱手段Ｂとしてのガスバーナ１０を燃焼させてフィルター部材６を加熱し、黒煙の煤を焼却してフィルター部材６を再生する。   As described above, black smoke soot can be collected by the filter member 6, but when black smoke soot accumulates in the filter member 6, the black smoke soot is periodically removed to regenerate the filter member 6. There is a need. For this reason, when black smoke is not generated at the black smoke generation source 1, after the damper 13 is closed (it is necessary to close it when the filter A is regenerated), the gas burner 10 as the filter heating means B is burned to filter the filter member 6 The filter member 6 is regenerated by incinerating black smoke soot.

フィルター部材６のメンテナンスを行うときは、点検蓋１８を外して点検口１７を開き、複数個（６個）のフィルター部材６と一緒に仕切り板１９を取り出し、仕切り板１９からフィルター部材６を抜き取ってセラミックファイバーブランケット９を交換したりするメンテナンスを行う。   When maintenance of the filter member 6 is performed, the inspection lid 18 is removed, the inspection port 17 is opened, the partition plate 19 is taken out together with a plurality of (six) filter members 6, and the filter member 6 is removed from the partition plate 19. Maintenance to replace the ceramic fiber blanket 9 is performed.

上記のような本発明の黒煙消煙装置の設計の一例について述べると、設計排気風量：１８０ｍ３／ｍｉｎ、フィルター面積１０ｍ２、フィルター通過風速：０．３ｍ／ｓ以下、初期圧損３００Ｐａ以下、消煙装置本体（炉体）内寸法：Ｌ（長さ）×Ｗ（幅）×Ｈ（高さ）＝２５５０ｍｍ×８００ｍｍ×８２０ｍｍ、再生するガスバーナの容量：１００ｋＷ、再生加熱温度：７００℃である。これに対して従来技術の一般的な直燃式消煙装置の場合、上記の本発明のものと同設計風量で限界設計した場合（７５０℃に加熱して０．３秒滞留させる）でも炉体内寸法：Ｌ×Ｗ×Ｈ＝４７９０ｍｍ×８００ｍｍ×８２０ｍｍ（Ｗ，Ｈを本発明のものに合わせた場合）、ガスバーナ容量：３０００ｋＷとなった。これにより本発明のものは、従来技術のものに比べて炉体容積４７％減、ガスバーナ容量９７％減できることがわかる。 An example of the design of the black smoke extinguishing apparatus of the present invention as described above will be described. Design exhaust air volume: 180 m 3 / min, filter area 10 m 2 , filter passing air speed: 0.3 m / s or less, initial pressure loss 300 Pa or less, Smoke eliminator body (furnace) internal dimensions: L (length) x W (width) x H (height) = 2550 mm x 800 mm x 820 mm, capacity of gas burner to regenerate: 100 kW, regeneration heating temperature: 700 ° C . On the other hand, in the case of the conventional direct combustion type smoke eliminator of the prior art, even when the limit design is performed with the same design air volume as that of the present invention described above (heating to 750 ° C. and holding for 0.3 seconds), the furnace Internal dimensions: L × W × H = 4790 mm × 800 mm × 820 mm (when W and H are matched with those of the present invention), gas burner capacity: 3000 kW. Thus, it can be seen that the present invention can reduce the furnace volume by 47% and the gas burner capacity by 97% compared to the prior art.

また消煙装置本体２内にフィルターＡを設ける場合、図８のような構造を採用してもよい。図８（ａ）の場合、断面略Ｖ字状のフィルターエレンメント３５が複数個並設されたフィルターＡを上部空間８と下部空間７との間に設けてあり、図８（ｂ）の場合、断面コ字状のフィルターエレメント３６が複数個並設されたフィルターＡを上部空間８と下部空間７との間に設けてある。上記フィルターエレメント３５，３６はセラミックファイバーブランケット、メタルファイバー、金属多孔質体、多孔質セラミック等の耐熱性があり且つ不燃性の多孔質体にて形成されている。また上記フィルターエレメント３５，３６は１個づつ着脱できるようになってもよい。   Moreover, when providing the filter A in the smoke eliminator main body 2, you may employ | adopt a structure like FIG. In the case of FIG. 8 (a), a filter A in which a plurality of filter elements 35 having a substantially V-shaped cross section are arranged in parallel is provided between the upper space 8 and the lower space 7, and in the case of FIG. 8 (b). A filter A having a plurality of U-shaped filter elements 36 arranged side by side is provided between the upper space 8 and the lower space 7. The filter elements 35 and 36 are formed of a heat-resistant and non-combustible porous material such as a ceramic fiber blanket, a metal fiber, a metal porous material, or a porous ceramic.
