Description
本発明は、主として蓄熱燃焼装置などに好適な蓄熱材に関する。
The present invention mainly relates to a heat storage material suitable for a heat storage combustion device or the like.
近年、工場排煙などに含まれる揮発性有機物質(以下、「ＶＯＣ」とも言う。)や未燃焼ガスが環境や人に対して悪影響を及ぼすことが問題となっている。このため、工場排煙などからこれらＶＯＣや未燃焼ガスを効率よく除去するために、蓄熱燃焼装置が使用されている。従来、この蓄熱燃焼装置では、蓄熱材として高価なセラミックハニカム構造体が用いられているが、処理対象ガスである工場排煙などに多量のダストが含まれていた場合、通気部の一部が閉塞して様々なトラブルが生じるようになる。そして、このようなダストによって蓄熱材の一部が閉塞した場合、高価なセラミックハニカム構造体を丸ごと交換しなければならず、非常にランニングコストが掛かるようになっていた。
In recent years, it has become a problem that volatile organic substances (hereinafter also referred to as “VOC”) and unburned gas contained in factory flue gas have an adverse effect on the environment and people. Therefore, in order to efficiently remove these VOCs and unburned gas from factory flue gas, a heat storage combustion device is used. Conventionally, in this heat storage combustion device, an expensive ceramic honeycomb structure is used as a heat storage material, but when a large amount of dust is contained in the factory exhaust gas, which is the gas to be treated, part of the ventilation part It will be blocked and various troubles will occur. When a part of the heat storage material is blocked by such dust, the expensive ceramic honeycomb structure has to be replaced in its entirety, resulting in a very high running cost.
そこで、例えば下記の特許文献１(日本国・特開２０００－２４０９２５号公報)では、蓄熱燃焼装置の蓄熱材を未処理(未脱臭)ガスの進行方向の上流側から下流側に向かって２以上のブロックに分割し、その進行方向の最上流側のブロックと最上流側から２番目のブロックとの間の隙間に、最上流側のブロックに向けた逆洗ノズルを設ける技術が開示されている。
かかる技術によれば、蓄熱体に割れを生じさせることなく、ダストによる閉塞が最も起こり易い未処理ガスの進行方向の最上流側近傍での蓄熱体の閉塞を効果的に防止することができるとされている。 Therefore, for example, in Patent Document 1 (Japanese Patent Laid-Open No. 2000-240925) described below, the heat storage material of the heat storage and combustion device is provided with two or more from the upstream side to the downstream side in the traveling direction of the untreated (undeodorized) gas. Is disclosed in which a backwash nozzle directed toward the most upstream side block is provided in the gap between the most upstream side block and the second most upstream block in the direction of travel. ..
According to such a technique, it is possible to effectively prevent clogging of the heat storage body in the vicinity of the most upstream side in the traveling direction of the untreated gas, which is most likely to be clogged by dust, without causing cracks in the heat storage body. Has been done.

According to such a technique, it is possible to effectively prevent clogging of the heat storage body in the vicinity of the most upstream side in the traveling direction of the untreated gas, which is most likely to be clogged by dust, without causing cracks in the heat storage body. Has been done.
しかしながら、上記の従来技術には、次のような問題があった。
すなわち、蓄熱材を２以上のブロックに分割すると共に、そのブロック間の隙間の所定位置に逆洗ノズルを設置しなければならないため、蓄熱燃焼装置の構造が複雑になると共に、イニシャルコストやランニングコストが上昇してＶＯＣや未燃焼ガスの除去を経済的且つ効率的に行うのが困難になる。
また、逆洗ノズルで逆洗されないセラミックハニカム構造体にダストが堆積した場合には、分割されているとは言え、これまでと同様に高価なセラミックハニカム構造体を丸ごと交換しなければならない。 However, the above conventional technique has the following problems.
That is, since the heat storage material must be divided into two or more blocks and the backwash nozzle must be installed at a predetermined position in the gap between the blocks, the structure of the heat storage and combustion device becomes complicated, and the initial cost and running cost are also increased. Rises, and it becomes difficult to remove VOC and unburned gas economically and efficiently.
Further, when dust is deposited on the ceramic honeycomb structure that is not backwashed by the backwash nozzle, the expensive ceramic honeycomb structure must be wholly replaced, although it is divided.

それゆえに、本発明の主たる目的は、簡単な構造であり、メンテナンス性や経済性に優れると共に、目的とする熱交換効率のものを簡単に得ることができる蓄熱材を提供することである。
Therefore, a main object of the present invention is to provide a heat storage material which has a simple structure, is excellent in maintainability and economical efficiency, and can easily obtain the target heat exchange efficiency.
上記の目的を達成するため、本発明は、例えば、図１から図２に示すように、蓄熱材を次のように構成した。
すなわち、金属またはセラミックからなり、ガス通流方向が開口したケーシング１２と、金属またはセラミックからなり、その軸方向がガス通流方向を向くようにして上記ケーシング１２内に充填された複数の管体１４とで構成されたことを特徴とする。 In order to achieve the above object, the present invention has a heat storage material configured as follows, for example, as shown in FIGS.
That is, acasing 12 made of metal or ceramic and having an opening in the gas flow direction, and a plurality of tubular bodies made of metal or ceramic and filled in the casing 12 with their axial directions facing the gas flow direction. It is characterized in that it is composed of 14 and.
すなわち、金属またはセラミックからなり、ガス通流方向が開口したケーシング１２と、金属またはセラミックからなり、その軸方向がガス通流方向を向くようにして上記ケーシング１２内に充填された複数の管体１４とで構成されたことを特徴とする。 In order to achieve the above object, the present invention has a heat storage material configured as follows, for example, as shown in FIGS.
That is, a
この発明では、蓄熱材がケーシング１２とその内部に充填された複数の管体１４とで構成されているので、管体１４の内径や肉厚を変更することで、蓄熱材の蓄熱性能を簡単に目的とするレベルに調節することができる。また、この管体１４はケーシング１２内に充填されているだけなので、管体１４の内部がダストによって閉塞した場合、従来のセラミックハニカム構造体のように蓄熱材全体を交換する必要はなく、閉塞した管体１４のみをケーシングから抜き出し、この管体１４を抜き出した部分に新しい管体１４を挿入するだけでメンテナンスを完了することができる。
なお、蓄熱材のケーシング１２および管体１４を加工が容易で耐熱性に優れる金属で形成した場合には、任意の形状の蓄熱材を経済的に製造することができる。一方、蓄熱材のケーシング１２および管体１４を蓄熱性に優れるセラミックで形成した場合には、熱交換効率の高い蓄熱材を得ることができる。 In this invention, since the heat storage material is composed of thecasing 12 and the plurality of pipe bodies 14 filled in the casing 12, the heat storage performance of the heat storage material can be simplified by changing the inner diameter and the wall thickness of the pipe body 14. It can be adjusted to the desired level. Further, since the tube body 14 is only filled in the casing 12, when the inside of the tube body 14 is clogged with dust, it is not necessary to replace the entire heat storage material as in the conventional ceramic honeycomb structure, and the blockage is prevented. The maintenance can be completed only by pulling out only the pipe body 14 that has been removed from the casing and inserting a new pipe body 14 into the portion from which the pipe body 14 has been removed.
When thecasing 12 and the tubular body 14 of the heat storage material are formed of a metal that is easy to process and has excellent heat resistance, the heat storage material having an arbitrary shape can be economically manufactured. On the other hand, when the casing 12 and the tubular body 14 of the heat storage material are formed of ceramic having excellent heat storage properties, the heat storage material having high heat exchange efficiency can be obtained.
なお、蓄熱材のケーシング１２および管体１４を加工が容易で耐熱性に優れる金属で形成した場合には、任意の形状の蓄熱材を経済的に製造することができる。一方、蓄熱材のケーシング１２および管体１４を蓄熱性に優れるセラミックで形成した場合には、熱交換効率の高い蓄熱材を得ることができる。 In this invention, since the heat storage material is composed of the
When the
本発明においては、前記の管体１４が円筒形であるのが好ましい。
この場合、隣接する管体１４同士および管体１４とケーシング１２とが面ではなく線で接触するようになり、管体１４の内外表面およびケーシング１２の内面で形成されるケーシング１２内の全表面積を極大化することができる。その結果、ケーシング１２の内部に導入された流体がケーシング１２内を通過する際の管体１４およびケーシング１２との接触面積が極大化され、蓄熱体と流体との間の熱交換効率を大幅に向上させることができる。 In the present invention, thetubular body 14 is preferably cylindrical.
In this case, the adjacenttubular bodies 14 and the tubular body 14 and the casing 12 come into contact with each other not by a surface but by a line, and the total surface area in the casing 12 formed by the inner and outer surfaces of the tubular body 14 and the inner surface of the casing 12. Can be maximized. As a result, the contact area between the tubular body 14 and the casing 12 when the fluid introduced into the casing 12 passes through the casing 12 is maximized, and the heat exchange efficiency between the heat storage body and the fluid is significantly increased. Can be improved.

さらに、本発明は、後述する実施形態に記載された特有の構成を付加することが好ましい。
Furthermore, in the present invention, it is preferable to add a unique configuration described in the embodiments described later.

According to the present invention, it is possible to provide a heat storage material that has a simple structure, is excellent in maintainability and economical efficiency, and can easily obtain the target heat exchange efficiency.
以下、本発明の一実施形態を図１から図２によって説明する。
図１は、本発明の蓄熱材１０の概略を示す部分拡大斜視図であり、図２は、その図１におけるＡ－Ａ’線断面を表す部分拡大断面図である。本発明の蓄熱材１０は、図示しない蓄熱燃焼装置などに設置され、それ自身が蓄熱・放熱を繰り返すことによって、高温のガスと低温のガスとの間で熱交換を行うためのものであり、これらの図が示すように、ケーシング１２と管体１４とで大略構成される。 An embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is a partially enlarged perspective view showing an outline of aheat storage material 10 of the present invention, and FIG. 2 is a partially enlarged sectional view showing a section taken along the line AA′ in FIG. The heat storage material 10 of the present invention is installed in a heat storage and combustion device (not shown) or the like, and is for performing heat exchange between a high temperature gas and a low temperature gas by repeating heat storage and heat dissipation by itself. As shown in these figures, the casing 12 and the tubular body 14 are generally configured.
図１は、本発明の蓄熱材１０の概略を示す部分拡大斜視図であり、図２は、その図１におけるＡ－Ａ’線断面を表す部分拡大断面図である。本発明の蓄熱材１０は、図示しない蓄熱燃焼装置などに設置され、それ自身が蓄熱・放熱を繰り返すことによって、高温のガスと低温のガスとの間で熱交換を行うためのものであり、これらの図が示すように、ケーシング１２と管体１４とで大略構成される。 An embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is a partially enlarged perspective view showing an outline of a
ケーシング１２は、蓄熱材１０の外枠を形成する容器体であり、スチール(ＳＳ)やステンレス(ＳＵＳ)或いはハステロイ（ヘインズ社登録商標）と言った金属、またはアルミナやジルコニア或いはコージェライトと言ったセラッミク等の高耐熱材料で形成される。
このケーシング１２は、互いに対面する一対の面(図示実施形態の場合は上下両面)が開口されており、開口された面の一方(図示実施形態の場合は下面側)には、金属メッシュで構成され、後述する管体１４をケーシング１２内に収容した際に、その管体１４がケーシング１２内から脱落しないように支持する、通気性の支持部材１６が張設されている。 Thecasing 12 is a container body that forms the outer frame of the heat storage material 10, and is a metal such as steel (SS), stainless steel (SUS), or Hastelloy (registered trademark of Haynes Co.), or alumina, zirconia, or cordierite. It is made of highly heat-resistant material such as ceramic.
Thecasing 12 has a pair of surfaces (upper and lower surfaces in the illustrated embodiment) facing each other opened, and one of the opened surfaces (the lower surface side in the illustrated embodiment) is made of a metal mesh. A breathable support member 16 is stretched to support the tubular body 14 so that the tubular body 14 does not fall out of the casing 12 when the tubular body 14 described later is housed in the casing 12.
このケーシング１２は、互いに対面する一対の面(図示実施形態の場合は上下両面)が開口されており、開口された面の一方(図示実施形態の場合は下面側)には、金属メッシュで構成され、後述する管体１４をケーシング１２内に収容した際に、その管体１４がケーシング１２内から脱落しないように支持する、通気性の支持部材１６が張設されている。 The
The
なお、図示実施形態では、ケーシング１２を四角柱状に形成する場合を示しているが、このケーシング１２の形状はこれに限定されるものではなく、例えば、図示しないが、上下両面(天井面と底面)が開口し、下面(底面)側に支持部材が張設された円柱状や三角柱状のものなどであっても良い。
また、このケーシング１２の形態(形状・サイズなど)やその素材は、蓄熱材１０が適用される各機器からの要求に応じて適宜設定される。 Although the illustrated embodiment shows the case where thecasing 12 is formed in a quadrangular prism shape, the shape of the casing 12 is not limited to this. For example, although not shown, the upper and lower surfaces (the ceiling surface and the bottom surface) are illustrated. ) May be opened, and a columnar or triangular columnar shape in which a supporting member is stretched on the lower surface (bottom surface) side may be used.
Further, the form (shape, size, etc.) of thecasing 12 and the material thereof are appropriately set according to the requirements from each device to which the heat storage material 10 is applied.
また、このケーシング１２の形態(形状・サイズなど)やその素材は、蓄熱材１０が適用される各機器からの要求に応じて適宜設定される。 Although the illustrated embodiment shows the case where the
Further, the form (shape, size, etc.) of the
管体１４は、主として蓄熱材１０の蓄熱・放熱を掌る部材であり、上述したケーシング１２と同様に、スチール(ＳＳ)やステンレス(ＳＵＳ)或いはハステロイ（ヘインズ社登録商標）と言った金属、またはアルミナやジルコニア或いはコージェライトと言ったセラッミク等の高耐熱材料で形成される。
図示実施形態では、この管体１４が、ケーシング１２の高さと略同等の長さに形成されると共に、その軸方向に直交する方向の断面が円形状、すなわち円筒形に形成されている。なお、管体１４の形状は、上記の円筒形に限定されるものではなく、その軸方向に直交する方向の断面が多角形状(角筒形)などであっても良い。しかしながら、管体１４の形状を円筒形とすることによって、隣接する管体１４同士および管体１４とケーシング１２との全てが面ではなく線で接触するようになり、管体１４の内外表面およびケーシング１２の内面で形成されるケーシング１２内の表面積を極大化することができる。 Thetube body 14 is a member mainly responsible for heat storage and heat dissipation of the heat storage material 10, and like the casing 12 described above, a metal such as steel (SS), stainless steel (SUS), or Hastelloy (registered trademark of Haynes Co., Ltd.), Alternatively, it is formed of a high heat-resistant material such as ceramics such as alumina, zirconia, or cordierite.
In the illustrated embodiment, thetubular body 14 is formed to have a length substantially equal to the height of the casing 12, and the cross section in the direction orthogonal to the axial direction thereof is circular, that is, cylindrical. The shape of the tubular body 14 is not limited to the cylindrical shape described above, and the cross section in the direction orthogonal to the axial direction may be polygonal (square tubular) or the like. However, by making the shape of the tubular body 14 cylindrical, the adjacent tubular bodies 14 and all of the tubular body 14 and the casing 12 come into contact with each other not by a surface but by a line, and the inner and outer surfaces of the tubular body 14 and The surface area inside the casing 12 formed by the inner surface of the casing 12 can be maximized.
図示実施形態では、この管体１４が、ケーシング１２の高さと略同等の長さに形成されると共に、その軸方向に直交する方向の断面が円形状、すなわち円筒形に形成されている。なお、管体１４の形状は、上記の円筒形に限定されるものではなく、その軸方向に直交する方向の断面が多角形状(角筒形)などであっても良い。しかしながら、管体１４の形状を円筒形とすることによって、隣接する管体１４同士および管体１４とケーシング１２との全てが面ではなく線で接触するようになり、管体１４の内外表面およびケーシング１２の内面で形成されるケーシング１２内の表面積を極大化することができる。 The
In the illustrated embodiment, the
また、管体１４は、その軸方向がケーシング１２のガス通流方向である開口方向を向くようにしてケーシング１２内に隙間なく充填される。ここで、ケーシング１２内に管体１４を隙間なく充填することによって、接着剤などで固定手段を用いることなく、ケーシング１２内に管体１４を取着することができる。
Further, the tubular body 14 is filled in the casing 12 with no gap so that its axial direction faces the opening direction which is the gas flow direction of the casing 12. Here, by filling the tubular body 14 into the casing 12 without any gap, the tubular body 14 can be attached to the casing 12 without using a fixing means such as an adhesive.
なお、管体１４の形態(内径・肉厚・長さなど)やその素材は、蓄熱材１０が適用される各機器にて要求される蓄熱特性に応じて適宜設定される。
The form (inner diameter, wall thickness, length, etc.) of the tubular body 14 and its material are appropriately set according to the heat storage characteristics required by each device to which the heat storage material 10 is applied.
以上のように構成された蓄熱材１０によれば、蓄熱材１０がケーシング１２とその内部に隙間なく充填された複数の管体１４とで構成されるので、管体１４の形態(内径・肉厚・長さなど)やその素材を変更することで、蓄熱材１０の蓄熱性能を簡単に目的とするレベルに調節することができる。また、この管体１４はケーシング１２内にて隙間なく充填されているだけなので、管体１４の内部がダストによって閉塞した場合、閉塞した管体１４のみをケーシング１２から抜き出し、この管体１４を抜き出した部分に新しい管体１４を挿入するだけでメンテナンスを完了することができる。
According to the heat storage material 10 configured as described above, since the heat storage material 10 is composed of the casing 12 and the plurality of pipe bodies 14 filled in the interior thereof with no gaps, the form of the pipe body 14 (inner diameter/meat It is possible to easily adjust the heat storage performance of the heat storage material 10 to a target level by changing (thickness, length, etc.) and its material. Further, since the pipe body 14 is simply filled in the casing 12 without any gap, when the inside of the pipe body 14 is blocked by dust, only the closed pipe body 14 is extracted from the casing 12 and the pipe body 14 is removed. Maintenance can be completed simply by inserting a new pipe body 14 into the extracted portion.
なお、上述の実施形態では、支持部材１６を金属メッシュで構成する場合を示したが、この支持部材１６は、ケーシング１２内部への通気性を確保しつつ、その内部に充填した管体１４が脱落しないように保持できる態様のものであれば、その態様は如何なるものであってもよく、上記の金属メッシュに限定されるものではない。
In addition, in the above-mentioned embodiment, although the case where the supporting member 16 is made of a metal mesh has been shown, the supporting member 16 has a tubular body 14 filled therein while ensuring air permeability to the inside of the casing 12. Any form may be used as long as it can be held so as not to fall off, and the form is not limited to the above metal mesh.
また、上述の実施形態では、ケーシング１２内に管体１４を隙間なく充填する場合を示しているが、例えば、蓄熱性を除いた品質特性のうち圧力損失の低減が最も重要な特性であるような場合には、図示しないスペーサーなどを介して隣接する管体１４同士が空間を置いて配置されるようにしてもよい。
Further, in the above-described embodiment, the case where the tubular body 14 is filled in the casing 12 without a gap is shown, but for example, reduction of pressure loss is the most important characteristic among quality characteristics excluding heat storage. In such a case, the tubular bodies 14 adjacent to each other may be arranged with a space therebetween via a spacer or the like not shown.
その他に、当業者が想定できる範囲で種々の変更を行えることは勿論である。
Besides, it goes without saying that various changes can be made within the range that can be expected by those skilled in the art.
