Description

本発明は工業炉の放熱回収装置に関する。   The present invention relates to a heat recovery device for an industrial furnace.

燃焼炉、ガス化炉、改質炉等の工業炉においては、内部温度が１０００℃に近い温度或いはそれよりも高い温度に保持されるものがあり、このような高温の炉においては、通常、炉壁内面に耐火物層を設けることによって、炉壁を保護すると共に、高温の熱が大気に放熱されるのを防止するようにしている。   In industrial furnaces such as combustion furnaces, gasification furnaces, reforming furnaces, etc., there are those in which the internal temperature is maintained at a temperature close to or higher than 1000 ° C. In such a high-temperature furnace, By providing a refractory layer on the inner surface of the furnace wall, the furnace wall is protected and high-temperature heat is prevented from being radiated to the atmosphere.

上記したような工業炉は、周囲が大気温度に保持されている場合が多く、そのために、炉壁を断熱して放熱を防止することにより熱効率を高めることが従来より行われており、例えば複数層の耐火物層を形成する等によって断熱を図るようにしたものが実施されている。   In the industrial furnace as described above, the surroundings are often kept at the atmospheric temperature, and for that reason, it has been conventionally performed to increase the thermal efficiency by insulating the furnace wall and preventing heat radiation, for example, a plurality of In some cases, heat insulation is achieved, for example, by forming a refractory layer.

従来、鉄鍋炉等において耐火物層を複数層としたものが特許文献１に示されている。   Conventionally, Patent Document 1 discloses a structure in which a plurality of refractory layers are used in an iron pan furnace or the like.

特開２００７−１０１０６４号公報JP 2007-101064 A

しかしながら、前述の如く、高温を保持する工業炉において、炉内面に複数層の耐火物層を設けることで放熱を防止するようにしたものにおいては、耐火物層を形成することが非常に大変でコストが増大するという問題があると共に、耐火物層の層厚が厚くなることにより炉内の必要空間を確保するためには工業炉が大型化するという問題を有していた。   However, as described above, in an industrial furnace that maintains a high temperature, in a case where heat radiation is prevented by providing a plurality of refractory layers on the inner surface of the furnace, it is very difficult to form a refractory layer. In addition to the problem that the cost increases, there is a problem that the industrial furnace becomes large in order to secure the necessary space in the furnace by increasing the thickness of the refractory layer.

本発明は、斯かる実情に鑑みてなしたもので、工業炉に容易に設置することができて工業炉からの放熱により加熱用ガス流体を加熱することにより加熱されたガス流体を有効に利用でき、炉壁の層厚を小さくしても熱の損失を抑えることができるようにした工業炉の放熱回収装置を提供しようとするものである。   The present invention has been made in view of such circumstances, and can be easily installed in an industrial furnace, and effectively uses the gas fluid heated by heating the gas fluid for heating by heat radiation from the industrial furnace. Therefore, an object of the present invention is to provide a heat recovery device for an industrial furnace that can suppress heat loss even if the layer thickness of the furnace wall is reduced.

本発明は、炉壁の外面に、炉壁の一部を間隔を隔てて覆うように組み付けられ且つ加熱用ガス流体の入口配管と加熱されたガス流体の出口配管を備えたカバー本体と、炉壁の他部を間隔を隔てて覆うように前記カバー本体に組み付けられる蓋体とを備えたことを特徴とする工業炉の放熱回収装置、に係るものである。   The present invention relates to a cover main body that is assembled to an outer surface of a furnace wall so as to cover a part of the furnace wall with a space therebetween, and includes a heating gas fluid inlet pipe and a heated gas fluid outlet pipe, The present invention relates to a heat recovery device for an industrial furnace, comprising a lid that is assembled to the cover main body so as to cover the other part of the wall with a gap.

上記工業炉の放熱回収装置において、前記カバー本体が略矩形のリング状を有し、前記蓋体がカバー本体の両側に組み付けられていてもよい。   In the heat recovery device for an industrial furnace, the cover body may have a substantially rectangular ring shape, and the lid body may be assembled on both sides of the cover body.

又、上記工業炉の放熱回収装置において、前記工業炉は酸化ガス供給配管とガス化ガス入口配管と改質ガス出口配管とを有する改質炉であり、前記カバー本体は前記酸化ガス供給配管とガス化ガス入口配管と改質ガス出口配管が貫通する貫通口を有することは好ましい。   Further, in the heat recovery device for an industrial furnace, the industrial furnace is a reforming furnace having an oxidizing gas supply pipe, a gasified gas inlet pipe, and a reformed gas outlet pipe, and the cover body has the oxidizing gas supply pipe. It is preferable to have a through-hole through which the gasification gas inlet pipe and the reformed gas outlet pipe pass.

本発明の工業炉の放熱回収装置によれば、加熱用ガス流体の入口配管と加熱されたガス流体の出口配管を備えて炉壁の一部を覆うように組み付けられるカバー本体と、炉壁の他部を覆うようにカバー本体に組み付けられる蓋体とからなる放熱回収装置を設けたので、放熱回収装置は工業炉に容易に設置することができ、しかも、加熱用ガス流体の入口配管から供給した加熱用ガス流体を工業炉からの放熱により加熱し、得られた加熱後のガス流体を有効利用することで、炉壁からの放熱が有効利用され、よって、工業炉の炉壁の層厚を小さくして建設コストを低減できると共に工業炉を小型化できるという優れた効果を奏し得る。   According to the industrial furnace heat radiation recovery apparatus of the present invention, a cover main body that includes an inlet pipe for a heating gas fluid and an outlet pipe for a heated gas fluid so as to cover a part of the furnace wall, Since a heat dissipation recovery device consisting of a lid that is assembled to the cover body so as to cover the other part is provided, the heat dissipation recovery device can be easily installed in an industrial furnace, and is supplied from the inlet piping of the heating gas fluid The heated gas fluid is heated by heat radiation from an industrial furnace, and the obtained gas fluid is effectively used to effectively use heat radiation from the furnace wall. As a result, the construction cost can be reduced and the industrial furnace can be downsized.

以下、本発明の実施の形態を図示例と共に説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図３は発明を工業炉である改質炉に適用した場合の一実施例であり、改質炉１は、図１に示すように炉壁によって上下に細長い筒形を有しており、改質炉１の上端には酸素又は空気からなる酸化ガス２を供給する酸化ガス供給配管３が設けてあり、更に、改質炉１の上端近傍の一側面（図１の左側面）には図示しないガス化炉からのガス化ガス４を導入するガス化ガス入口配管５が設けてあり、ガス化ガス４の一部を前記酸化ガス２によって燃焼させることにより高温（例えば１３００℃）を保持して、ガス化ガス４の改質を行うようになっている。又、改質炉１の下端近傍の他側面（図１の右側面）には改質によって生成した改質ガス６を導出する改質ガス出口配管７が設けられている。   1 to 3 show an embodiment in which the invention is applied to a reforming furnace which is an industrial furnace, and the reforming furnace 1 has a cylindrical shape elongated vertically by a furnace wall as shown in FIG. In addition, an oxidizing gas supply pipe 3 for supplying an oxidizing gas 2 made of oxygen or air is provided at the upper end of the reforming furnace 1, and one side surface in the vicinity of the upper end of the reforming furnace 1 (the left side surface in FIG. 1). Is provided with a gasification gas inlet pipe 5 for introducing a gasification gas 4 from a gasification furnace (not shown), and a part of the gasification gas 4 is burned by the oxidizing gas 2 to raise the temperature (for example, 1300 ° C.). And the gasification gas 4 is reformed. Further, a reformed gas outlet pipe 7 for leading the reformed gas 6 generated by the reforming is provided on the other side surface near the lower end of the reforming furnace 1 (right side surface in FIG. 1).

図１、図２中、９は本発明の放熱回収装置８を構成するカバー本体であり、該カバー本体９は、所要幅の略矩形のリング状を有して前記改質炉１を長手方向に所要の間隔を隔てて包囲するよう形成されており、カバー本体９の上端近傍の他側面（図１の右側面）には加熱用空気１０（加熱用ガス流体）を導入する加熱用空気の入口配管１１（加熱用ガス流体の入口配管）が設けてあり、又、前記カバー本体９の下端近傍の一側面（図１の左側面）には加熱された空気１２（加熱されたガス流体）を導出する出口配管１３が設けられている。又、カバー本体９には、前記改質炉１に備えた前記酸化ガス供給配管３、ガス化ガス入口配管５及び改質ガス出口配管７が貫通する貫通口１４が設けられている。従って、改質炉１に組み付けるようにした前記カバー本体９の加熱用空気の入口配管１１及び加熱された空気の出口配管１３と、前記改質炉１のガス化ガス入口配管５及び改質ガス出口配管７とは、１つの面内に配置されるようになっている。   1 and 2, reference numeral 9 denotes a cover main body constituting the heat radiation recovery apparatus 8 of the present invention. The cover main body 9 has a substantially rectangular ring shape with a required width so that the reforming furnace 1 extends in the longitudinal direction. The heating air for introducing the heating air 10 (heating gas fluid) to the other side surface (the right side surface in FIG. 1) in the vicinity of the upper end of the cover body 9 is formed to surround the cover body 9 at a necessary interval. An inlet pipe 11 (heating gas fluid inlet pipe) is provided, and heated air 12 (heated gas fluid) is provided on one side surface (left side surface in FIG. 1) near the lower end of the cover body 9. Is provided with an outlet pipe 13. Further, the cover body 9 is provided with a through-hole 14 through which the oxidizing gas supply pipe 3, gasification gas inlet pipe 5 and reformed gas outlet pipe 7 provided in the reforming furnace 1 pass. Accordingly, the heating air inlet pipe 11 and the heated air outlet pipe 13 of the cover body 9, the gasified gas inlet pipe 5 of the reforming furnace 1, and the reformed gas are assembled to the reforming furnace 1. The outlet pipe 7 is arranged in one plane.

一方、前記カバー本体９における前記酸化ガス供給配管３、ガス化ガス入口配管５及び改質ガス出口配管７が貫通する貫通口１４の部分は、図３に示すように、カバー本体９が分割線１５によって分割されており、該分割線１５の部分を溶接或いはボルト継手等にて接続することによりカバー本体９は改質炉１に組み付けられるようになっている。尚、大型の改質炉１の場合には、前記カバー本体９は分割線１５以外の部分においても分割するようにしてもよい。   On the other hand, as shown in FIG. 3, the cover body 9 has a dividing line at a portion of the through-hole 14 through which the oxidizing gas supply pipe 3, the gasification gas inlet pipe 5 and the reformed gas outlet pipe 7 pass. The cover main body 9 is assembled to the reforming furnace 1 by connecting portions of the dividing line 15 by welding or bolt joints. In the case of the large reforming furnace 1, the cover main body 9 may be divided at portions other than the dividing line 15.

前記カバー本体９には、改質炉１の炉壁を貫通して設けられる温度計１６、サンプリング管１７或いは覗き窓１８等の計装器が貫通するようにした計装器取付口１９が形成されている。   The cover main body 9 is formed with an instrument attachment port 19 through which an instrument such as a thermometer 16, a sampling tube 17, or a viewing window 18 provided through the furnace wall of the reforming furnace 1 penetrates. Has been.

又、図１、図２中、２０，２１は本発明の放熱回収装置８を構成する蓋体であり、該蓋体２０，２１は、前記カバー本体９の幅方向両側にボルト継手２２等によって着脱可能に組み付けることにより、前記カバー本体９によって包囲された改質炉１の他部を所要の間隔を隔てて包囲するようになっており、前記カバー本体９と蓋体２０，２１とからなる放熱回収装置８によって、改質炉１の全周が包囲されるようになっている。   1 and 2, reference numerals 20 and 21 denote cover bodies constituting the heat radiation recovery device 8 of the present invention, and the cover bodies 20 and 21 are provided by bolt joints 22 or the like on both sides of the cover body 9 in the width direction. By detachably assembling, the other part of the reforming furnace 1 surrounded by the cover main body 9 is surrounded with a predetermined interval, and consists of the cover main body 9 and the lid bodies 20 and 21. The entire periphery of the reforming furnace 1 is surrounded by the heat radiation recovery device 8.

上記した如く改質炉１の外周を熱回収装置８で包囲した場合に、改質炉１と熱回収装置８との間の空気の対流伝熱によって前記カバー本体９及び蓋体２０，２１の温度が上昇し、該カバー本体９及び蓋体２０，２１の外表面から自然対流によって外部放熱される問題がある。   As described above, when the outer periphery of the reforming furnace 1 is surrounded by the heat recovery device 8, the cover main body 9 and the lid bodies 20, 21 of the cover body 9 and the lid bodies 20, 21 are convectively transferred by air between the reforming furnace 1 and the heat recovery device 8. There is a problem that the temperature rises and heat is radiated from the outer surfaces of the cover body 9 and the lid bodies 20 and 21 by natural convection.

この問題を防止するために、前記カバー本体９及び蓋体２０，２１の外表面には、図２に示すように薄い保温層２３を設け、これによって外部放熱を最小限に抑えるようにしている。保温層２３の熱伝達率は温度が低いほど小さいため、温度が低いカバー本体９及び蓋体２０，２１の外表面に保温層２３を設けたことにより放熱抑止効果を高めることができる。温度が低い部分に設ける断熱層としては安価なものを使用することができ、例えばグラスウール、ロックウール等の鉱物繊維系断熱材、ポリスチレン、ポリエチレン、硬質ウレタンフォーム等の発泡樹脂系断熱材などを用いることができる。   In order to prevent this problem, a thin heat insulating layer 23 is provided on the outer surface of the cover body 9 and the lids 20 and 21 as shown in FIG. 2, thereby minimizing external heat dissipation. . Since the heat transfer coefficient of the heat retaining layer 23 is smaller as the temperature is lower, the heat dissipation suppressing effect can be enhanced by providing the heat retaining layer 23 on the outer surfaces of the cover body 9 and the lid bodies 20 and 21 having a lower temperature. As the heat insulating layer provided in the low temperature part, an inexpensive one can be used, for example, mineral fiber heat insulating materials such as glass wool and rock wool, and foamed resin heat insulating materials such as polystyrene, polyethylene and rigid urethane foam are used. be able to.

図１、図２では、カバー本体９の両側に蓋体２０，２１を組み付けるようにした場合について例示したが、カバー本体９によって改質炉１の大半を包囲して、残りの部分を１つ蓋体によって包囲するようにしてもよい。   1 and 2 exemplify the case where the lids 20 and 21 are assembled on both sides of the cover main body 9, the cover main body 9 surrounds most of the reforming furnace 1, and the remaining part is one. You may make it surround with a cover body.

次に、上記実施例の作動を説明する。   Next, the operation of the above embodiment will be described.

図１に示す貫通口１４の部分が前記酸化ガス供給配管３、ガス化ガス入口配管５及び改質ガス出口配管７に対応するようにカバー本体９の構成部材を配置して、分割線１５において溶接或いはボルト継手等で接続することによりカバー本体９を改質炉１に組み付ける。このとき、カバー本体９の計装器取付口１９に、改質炉１に備えられた温度計１６、サンプリング管１７或いは覗き窓１８等の計装器を貫通させて配置する。   In the dividing line 15, the components of the cover body 9 are arranged so that the through-hole 14 shown in FIG. 1 corresponds to the oxidizing gas supply pipe 3, the gasification gas inlet pipe 5 and the reformed gas outlet pipe 7. The cover body 9 is assembled to the reforming furnace 1 by welding or connecting with a bolt joint or the like. At this time, an instrument such as a thermometer 16, a sampling tube 17, or a viewing window 18 provided in the reforming furnace 1 is disposed through the instrument mounting port 19 of the cover body 9.

続いて、図１、図２に示す蓋体２０，２１をボルト継手２２等によってカバー本体９に組み付けることにより、放熱回収装置８を構成する。   Subsequently, the heat dissipation recovery device 8 is configured by assembling the lid bodies 20 and 21 shown in FIGS.

上記したように放熱回収装置８を備えた改質炉１において、上端のガス化ガス入口配管５からガス化ガス４を導入すると共に、酸化ガス供給配管３から酸化ガス２を供給して、ガス化ガス４の一部を前記酸化ガス２により燃焼させて高温（例えば１３００℃）を保持することにより、ガス化ガス４の改質を行う。改質によって生成された改質ガス６は、改質炉１下端の改質ガス出口配管７から導出される。   As described above, in the reforming furnace 1 equipped with the heat radiation recovery device 8, the gasified gas 4 is introduced from the gasified gas inlet pipe 5 at the upper end, and the oxidizing gas 2 is supplied from the oxidizing gas supply pipe 3. The gasification gas 4 is reformed by burning a part of the gasification gas 4 with the oxidizing gas 2 and maintaining a high temperature (for example, 1300 ° C.). The reformed gas 6 generated by the reforming is led out from the reformed gas outlet pipe 7 at the lower end of the reforming furnace 1.

このとき、カバー本体９の上部に設けた加熱用空気の入口配管１１から放熱回収装置８内に加熱用空気１０を供給すると、加熱用空気１０は改質炉１の表面に沿って流れる間に改質炉１からの放熱を奪うことにより自身は加熱され、加熱された空気１２となってカバー本体９の下部に設けた出口配管１３から導出される。   At this time, when the heating air 10 is supplied into the heat dissipation recovery device 8 from the heating air inlet pipe 11 provided at the upper part of the cover body 9, the heating air 10 flows while flowing along the surface of the reforming furnace 1. By depriving the heat release from the reforming furnace 1 itself is heated, and becomes heated air 12 which is led out from an outlet pipe 13 provided at the lower part of the cover body 9.

従って、出口配管１３から導出される加熱された空気１２は、図示しないガス化炉等の燃焼空気として有効に利用することができる。   Therefore, the heated air 12 led out from the outlet pipe 13 can be effectively used as combustion air for a gasification furnace (not shown).

上記した放熱回収装置８はカバー本体９に対して蓋体２０，２１が着脱可能に備えられているので、蓋体２０，２１を取り外すことによって改質炉１のメンテナンスを容易に行うことができる。   Since the heat dissipation recovery device 8 is provided with the lids 20 and 21 so as to be detachable with respect to the cover body 9, the maintenance of the reforming furnace 1 can be easily performed by removing the lids 20 and 21. .

上記したように、放熱回収装置８は改質炉１に容易に組み立てて設置することができ、しかも、加熱用空気の入口配管１１から導入した加熱用空気１０は改質炉１の炉壁からの放熱により加熱され、出口配管１３から加熱された空気１２となって取り出されるので燃焼空気として有効利用することができ、よって、炉壁からの放熱による熱的損失は防止され、炉壁を構成する耐火物層等の層厚を小さくすることができて建設コストを低減することができると共に、改質炉１を小型化することができる。   As described above, the heat radiation recovery device 8 can be easily assembled and installed in the reforming furnace 1, and the heating air 10 introduced from the heating air inlet pipe 11 is fed from the furnace wall of the reforming furnace 1. It is heated by heat radiation and is taken out as heated air 12 from the outlet pipe 13 so that it can be effectively used as combustion air. Therefore, thermal loss due to heat radiation from the furnace wall is prevented, and the furnace wall is configured. The thickness of the refractory layer to be reduced can be reduced, the construction cost can be reduced, and the reforming furnace 1 can be downsized.

尚、本発明の工業炉の放熱回収装置は、上述の実施例にのみ限定されるものではなく、改質炉以外の燃焼炉、ガス化炉等の種々の工業炉に適用できること、又、上述の実施例では改質炉の放熱で加熱用空気を加熱する場合について説明したが、空気以外のガス流体の加熱にも適用できること、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ること、等は勿論である。   Note that the industrial furnace heat dissipation recovery device of the present invention is not limited to the above-described embodiments, but can be applied to various industrial furnaces such as combustion furnaces other than reforming furnaces, gasification furnaces, and the like. In the above embodiment, the case where the heating air is heated by the heat radiation of the reforming furnace has been described. However, the present invention can be applied to the heating of a gas fluid other than air, and various modifications are made without departing from the scope of the present invention.
