Description

本発明は、被保温部からの放熱を防止するための断熱構造に関するものである。   The present invention relates to a heat insulating structure for preventing heat dissipation from a heat retaining portion.

グラスウール、ロックウールまたはケイ酸カルシウムからなる断熱材は、ウレタンフォームなどに比べ断熱性が低く、厚さが必要となり設置スペースが大きくなる。一方、ウレタンフォームや真空断熱材は、断熱性に優れるので設置スペースを小さくできるが、耐熱温度が１００℃程度と比較的低く、ボイラや蒸気配管の断熱には使用できない。また、エアロジェル断熱材は、断熱性および耐熱性の双方を備えるが、コストが高く、従来の断熱材の代替としては使用しにくい。   A heat insulating material made of glass wool, rock wool, or calcium silicate has a lower heat insulating property than urethane foam, requires a thickness, and requires a large installation space. On the other hand, urethane foam and vacuum heat insulating material are excellent in heat insulating properties, so that the installation space can be reduced. However, the heat resistant temperature is relatively low at about 100 ° C. and cannot be used for heat insulation of boilers and steam pipes. Moreover, although an airgel heat insulating material is provided with both heat insulation and heat resistance, cost is high and it is hard to use it as a substitute of the conventional heat insulating material.

その他、従来、下記特許文献１に開示されるように、第一保温材（２０）と第二保温材（３０）とにより、断熱を図ることは公知である。但し、断熱性および耐熱性の双方を考慮した適切な断熱材の組合せを実現する上で、改善の余地がある。   In addition, conventionally, as disclosed in Patent Document 1 below, it is well known that heat insulation is achieved by the first heat insulating material (20) and the second heat insulating material (30). However, there is room for improvement in realizing an appropriate combination of heat insulating materials considering both heat insulating properties and heat resistance.

本発明が解決しようとする課題は、断熱性および耐熱性を確保しつつ、設置スペースの削減を図ることのできる断熱構造を提供することにある。   The problem to be solved by the present invention is to provide a heat insulating structure capable of reducing the installation space while ensuring heat insulating properties and heat resistance.

本発明は、前記課題を解決するためになされたもので、請求項１に記載の発明は、被保温部からの放熱を防止するための断熱構造であって、前記被保温部には、第一断熱材を介して第二断熱材が設けられ、前記第一断熱材は、前記第二断熱材よりも耐熱性に優れた材料からなり、前記第二断熱材は、前記第一断熱材よりも断熱性に優れた材料からなることを特徴とする断熱構造である。   The present invention has been made to solve the above-mentioned problems, and the invention according to claim 1 is a heat insulating structure for preventing heat dissipation from the heat retaining portion, and the heat retaining portion includes A second heat insulating material is provided via one heat insulating material, and the first heat insulating material is made of a material superior in heat resistance than the second heat insulating material, and the second heat insulating material is made from the first heat insulating material. Is a heat insulating structure characterized in that it is made of a material having excellent heat insulating properties.

断熱性に優れた材料を用いれば、断熱材の厚さを薄くできることになるが、耐熱温度が低い場合がある。ところが、請求項１に記載の発明によれば、耐熱性に優れた第一断熱材を介して、断熱性に優れた第二断熱材を設置することで、耐熱温度の問題を解消しつつ、コンパクトに断熱性を確保することができる。   If a material having excellent heat insulating properties is used, the thickness of the heat insulating material can be reduced, but the heat resistant temperature may be low. However, according to the invention described in claim 1, by installing the second heat insulating material excellent in heat insulation through the first heat insulating material excellent in heat resistance, while solving the problem of heat resistant temperature, It is possible to ensure heat insulation in a compact manner.

請求項２に記載の発明は、前記第一断熱材は、前記被保温部の温度よりも耐熱温度が高い材料から形成され、前記第一断熱材の外面における温度が前記第二断熱材の耐熱温度以下になるように、前記第一断熱材の厚さが設定されることを特徴とする請求項１に記載の断熱構造である。   According to a second aspect of the present invention, the first heat insulating material is formed of a material having a heat resistant temperature higher than the temperature of the heat retaining portion, and the temperature on the outer surface of the first heat insulating material is the heat resistant temperature of the second heat insulating material. The heat insulating structure according to claim 1, wherein a thickness of the first heat insulating material is set so as to be equal to or lower than a temperature.

請求項２に記載の発明によれば、第一断熱材および第二断熱材の双方をそれぞれの耐熱温度以下で使用しつつ、断熱性に優れた第二断熱材により、断熱材の設置スペースの削減を図ることができる。   According to invention of Claim 2, while using both the 1st heat insulating material and the 2nd heat insulating material below each heat-resistant temperature, by the 2nd heat insulating material excellent in heat insulation, of the installation space of heat insulating material. Reduction can be achieved.

さらに、請求項３に記載の発明は、前記第一断熱材は、エアロジェル断熱材であり、前記第二断熱材は、ウレタンフォームであることを特徴とする請求項１または請求項２に記載の断熱構造である。   Furthermore, in the invention described in claim 3, the first heat insulating material is an airgel heat insulating material, and the second heat insulating material is urethane foam. It is a heat insulation structure.

請求項３に記載の発明によれば、断熱性には優れるが耐熱性に劣るウレタンフォームを用いる場合、被保温部とウレタンフォームとの間に、耐熱性に優れたエアロジェル断熱材を介在させることで、ウレタンフォームの耐熱性の問題を解消しつつ、ウレタンフォームにより省スペースで断熱を図ることができる。しかも、コストが高いエアロジェル断熱材だけを用いた場合と比較して、低コストに施工することができる。   According to invention of Claim 3, when using the urethane foam which is excellent in heat insulation but is inferior in heat resistance, the airgel heat insulating material excellent in heat resistance is interposed between a heat retaining part and urethane foam. Thus, it is possible to achieve heat insulation in a space-saving manner with the urethane foam while solving the heat resistance problem of the urethane foam. And compared with the case where only the high cost airgel heat insulating material is used, it can construct at low cost.

本発明によれば、断熱性および耐熱性を確保しつつ、設置スペースの削減を図ることのできる断熱構造を実現することができる。   ADVANTAGE OF THE INVENTION According to this invention, the heat insulation structure which can aim at reduction of installation space can be implement | achieved, ensuring heat insulation and heat resistance.

以下、本発明の具体的実施例を図面に基づいて詳細に説明する。
図１は、本発明の断熱構造の一実施例を示す概略断面図である。 Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic sectional view showing an embodiment of the heat insulating structure of the present invention.

本発明の断熱構造１は、被保温部２からの放熱を防止するための複合断熱材である。被保温部２は、特に問わないが、たとえば、ボイラの缶体や、ボイラからの蒸気配管である。本実施例では、被保温部２は、流体が通されるパイプとされ、このパイプ内には、パイプ外よりも高温の液体および／または気体が通される。なお、被保温部２は、図示例では円形であるが、これに限定されないのは言うまでもない。   The heat insulating structure 1 of the present invention is a composite heat insulating material for preventing heat dissipation from the heat retaining portion 2. The heat retaining portion 2 is not particularly limited, and is, for example, a boiler body or a steam pipe from the boiler. In the present embodiment, the heat retaining portion 2 is a pipe through which a fluid is passed, and liquid and / or gas having a temperature higher than that outside the pipe is passed through the pipe. In addition, although the to-be-heated part 2 is circular in the example of illustration, it cannot be overemphasized that it is not limited to this.

被保温部２には、本実施例の断熱構造１として、第一断熱材３を介して第二断熱材４が設けられる。   The heat insulation part 2 is provided with a second heat insulating material 4 via a first heat insulating material 3 as the heat insulating structure 1 of the present embodiment.

第一断熱材３は、第二断熱材４よりも耐熱性に優れた材料からなる。つまり、第一断熱材３の耐熱温度は、第二断熱材４の耐熱温度よりも高い。   The first heat insulating material 3 is made of a material having higher heat resistance than the second heat insulating material 4. That is, the heat resistant temperature of the first heat insulating material 3 is higher than the heat resistant temperature of the second heat insulating material 4.

第二断熱材４は、第一断熱材３よりも断熱性に優れた材料からなる。つまり、第二断熱材４の熱伝導率は、第一断熱材３の熱伝導率よりも低い。   The second heat insulating material 4 is made of a material having better heat insulating properties than the first heat insulating material 3. That is, the heat conductivity of the second heat insulating material 4 is lower than the heat conductivity of the first heat insulating material 3.

第一断熱材３と第二断熱材４との組合せは、適宜に設定されるが、好ましい一例として、第一断熱材３はエアロジェル断熱材であり、第二断熱材４はウレタンフォームである。但し、第一断熱材３と第二断熱材４との組合せは、これに限定されるものではなく、たとえば、第一断熱材３がグラスウール、第二断熱材４が真空断熱材であってもよい。   Although the combination of the 1st heat insulating material 3 and the 2nd heat insulating material 4 is set suitably, as a preferable example, the 1st heat insulating material 3 is an airgel heat insulating material and the 2nd heat insulating material 4 is a urethane foam. . However, the combination of the 1st heat insulating material 3 and the 2nd heat insulating material 4 is not limited to this, For example, even if the 1st heat insulating material 3 is glass wool and the 2nd heat insulating material 4 is a vacuum heat insulating material. Good.

いずれにしても、第一断熱材３は、被保温部２の外面の温度よりも耐熱温度が高い材料から形成される。また、第一断熱材３の外面における温度が第二断熱材４の耐熱温度以下になるように、第一断熱材３の厚さが設定される。   Anyway, the 1st heat insulating material 3 is formed from the material whose heat-resistant temperature is higher than the temperature of the outer surface of the to-be-heated part 2. FIG. Further, the thickness of the first heat insulating material 3 is set so that the temperature on the outer surface of the first heat insulating material 3 is equal to or lower than the heat resistant temperature of the second heat insulating material 4.

これにより、第一断熱材３および第二断熱材４の双方をそれぞれ耐熱温度以下で使用しつつ、断熱性に優れた第二断熱材４により、断熱材の設置スペースの削減を図ることができる。なお、第二断熱材４は第一断熱材３よりも断熱性に優れるので（言い換えれば薄く施工できるので）、第一断熱材３の外面における温度が第二断熱材４の耐熱温度以下となる限りにおいて、第一断熱材３の厚さは薄いほど、全体として省スペースで断熱材を施工することができることになる。   Thereby, the installation space of a heat insulating material can be reduced by the 2nd heat insulating material 4 excellent in heat insulation, using both the 1st heat insulating material 3 and the 2nd heat insulating material 4 below heat-resistant temperature, respectively. . In addition, since the 2nd heat insulating material 4 is excellent in heat insulation than the 1st heat insulating material 3 (in other words, it can construct thinly), the temperature in the outer surface of the 1st heat insulating material 3 becomes below the heat-resistant temperature of the 2nd heat insulating material 4. As long as the thickness of the first heat insulating material 3 is thinner, the heat insulating material can be installed in a smaller space as a whole.

たとえば、ウレタンフォームは、断熱性に優れるため、所期の断熱性能を確保する上で、断熱材の厚さを薄くして使用できるが、耐熱性に劣り、被保温部２がボイラや蒸気配管のように比較的高温（たとえば１５０℃以上）の場合には使えない。そのような場合、被保温部２とウレタンフォーム（第二断熱材４）との間に、耐熱性に優れたエアロジェル断熱材（第一断熱材３）を介在させることで、ウレタンフォームの耐熱性の問題を解消しつつ、ウレタンフォームにより省スペースで断熱を図ることができる。その際、ウレタンフォームの温度が使用上限温度を超えないように、エアロジェル断熱材の厚さを決めればよいことになる。しかも、コストが高いエアロジェル断熱材だけを用いた場合と比較して、低コストに施工することができる。このようにして、断熱性や耐熱性を確保しつつ、省スペースで低コストに施工することができる。   For example, since urethane foam has excellent heat insulation properties, it can be used with a thin heat insulating material in order to ensure the desired heat insulation performance, but it is inferior in heat resistance, and the heat retaining part 2 is a boiler or steam pipe. It cannot be used when the temperature is relatively high (for example, 150 ° C. or higher). In such a case, the heat resistance of the urethane foam is obtained by interposing an airgel heat insulating material (first heat insulating material 3) excellent in heat resistance between the heat retaining portion 2 and the urethane foam (second heat insulating material 4). While eliminating the problem of property, heat insulation can be achieved in a space-saving manner with urethane foam. At that time, the thickness of the airgel heat insulating material may be determined so that the temperature of the urethane foam does not exceed the upper limit temperature for use. And compared with the case where only the high cost airgel heat insulating material is used, it can construct at low cost. In this way, it is possible to construct the space-saving and low-cost while ensuring heat insulation and heat resistance.

図２は、蒸気配管（１００Ａ）に対してある条件を仮定して、断熱材厚さと年間総費用との関係の一例を示す概略図である。横軸として示す断熱材厚さを増すほど（つまり右側へ行くに従って）、放熱は下がるが、断熱材のコストがかかることになる。縦軸として示す年間総費用は、配管の単位長さ当たりの年間コストであり、断熱材の材料費の他、放熱を燃料費として算出している。   FIG. 2 is a schematic diagram showing an example of the relationship between the insulation thickness and the total annual cost, assuming certain conditions for the steam pipe (100A). As the thickness of the heat insulating material shown as the horizontal axis increases (that is, as it goes to the right side), the heat dissipation decreases, but the cost of the heat insulating material increases. The total annual cost shown on the vertical axis is the annual cost per unit length of piping, and heat dissipation is calculated as fuel cost in addition to the material cost of the heat insulating material.

図中、線ａはロックウール、線ｂはグラスウール、線ｃはマイクロサーム、線ｄはパイロブランケット、線ｅはエアロジェル断熱材、線ｆおよび線ｇはグラスウール（第一断熱材）とウレタン（第二断熱材）との組合せ（条件が異なる）、線ｈはエアロジェル（第一断熱材）とウレタン（第二断熱材）との組合せを示している。   In the figure, line a is rock wool, line b is glass wool, line c is microtherm, line d is a pyro blanket, line e is an airgel insulation, lines f and g are glass wool (first insulation) and urethane ( Combination (second heat insulating material) (conditions are different), line h indicates a combination of airgel (first heat insulating material) and urethane (second heat insulating material).

いずれの断熱材も、概ね下に凸の曲線を描くことになり、各曲線の最下点（年間総費用が最少となる点）における断熱材厚さを採用することで、最も低コストに断熱を図ることができることになる。   All of the insulation materials will draw a downwardly convex curve. By adopting the insulation material thickness at the lowest point of each curve (the point where the total annual cost is the smallest), the insulation is made at the lowest cost. Can be achieved.

たとえば、エアロジェル断熱材を単独で用いた場合（ｅ）、最下点のコストは４０６２円／ｍ年であるが、ウレタンと組み合わせることで（ｈ）３４７３円／ｍ年に下げることができる（数値は図３より）。なお、エアロジェルとウレタンの各厚さは、ウレタンの耐熱温度を考慮して、前述した手法により、コストの高いエアロジェルの使用を最小限とした形で設定するのがコスト面からはよい。   For example, when an airgel heat insulating material is used alone (e), the lowest point cost is 4062 yen / m year, but it can be reduced to (h) 3473 yen / m year by combining with urethane ( (Figures are from Figure 3). In view of the heat resistance temperature of urethane, the thicknesses of the airgel and the urethane are preferably set from the above-described method in a manner that minimizes the use of expensive airgel.

一方、図３は、図２と同様の条件で、断熱材厚さと放熱量（配管の単位長さ当たりの放熱量）との関係の一例を示す概略図である。図３中の各線ａ〜ｈ（但しｆ省略）は、図２中の各線ａ〜ｈと対応した断熱材を示しており、丸で囲んだ箇所が、図２における前記最下点と対応する。   On the other hand, FIG. 3 is a schematic diagram showing an example of the relationship between the thickness of the heat insulating material and the heat radiation amount (heat radiation amount per unit length of piping) under the same conditions as in FIG. Each line a to h (f is omitted) in FIG. 3 shows a heat insulating material corresponding to each line a to h in FIG. 2, and a circled portion corresponds to the lowest point in FIG. .

図３では、横軸と平行に左側へ行くほど、同じ放熱量で断熱材の厚さを薄くできることになる。また、下方へ行くほど放熱量が減るので、有効な断熱を図ることができることになる。さらに、各曲線上、丸で囲んだ箇所に近いほど、その断熱材を用いた場合のコストを低減できることになる。   In FIG. 3, the thickness of the heat insulating material can be reduced with the same amount of heat radiation as it goes to the left in parallel with the horizontal axis. Moreover, since the amount of heat radiation decreases as it goes downward, effective heat insulation can be achieved. Further, the closer to the circled locations on each curve, the lower the cost when using the heat insulating material.

このように、検討対象の断熱材やその組合せについて、断熱材厚さと放熱量との関係を明らかにし、同じ放熱量なら断熱材厚さの小さくなる断熱材の組合せを採用し、同じ断熱材厚さなら放熱量の少ない断熱材の組合せを採用し、その際、コスト最下点付近で使用するよう設計するのが好ましい。   In this way, the relationship between the heat insulating material thickness and the heat dissipation amount is clarified for the heat insulating material to be examined and its combination, and if the heat dissipation amount is the same, the heat insulating material combination with a smaller heat insulating material thickness is adopted, and the same heat insulating material thickness is adopted. In other words, it is preferable to employ a combination of heat insulating materials with a small amount of heat dissipation, and to design it to be used near the lowest cost point.

本発明の断熱構造１は、前記実施例の構成に限らず、適宜変更可能である。たとえば、前記実施例では第一断熱材３と第二断熱材４とを用いたが、これ以外の断熱材をさらに同様の手法で組み合わせてもよい。   The heat insulation structure 1 of this invention is not restricted to the structure of the said Example, It can change suitably. For example, in the said Example, although the 1st heat insulating material 3 and the 2nd heat insulating material 4 were used, you may combine another heat insulating material with the same method further.
