Description

本考案は煙突に係り、建物内に設置される非常用発電機を駆動するガスタービンエンジンやディーゼルエンジンの排ガス、ボイラーの排ガス或いは産業廃棄物焼却炉の排ガスを建物外に導いて放散させるに好適な煙突に関する。   The present invention relates to a chimney and is suitable for directing and radiating exhaust gas from a gas turbine engine or diesel engine that drives an emergency generator installed in a building, exhaust gas from a boiler, or exhaust gas from an industrial waste incinerator. Related to the chimney.

従来、建物内に設置される非常用発電機を駆動するガスタービンエンジンやディーゼルエンジンの排ガス、ボイラーの排ガス或いは産業廃棄物焼却炉の排ガスなどを建物外に導いて放散させる煙突として、例えば特許文献１に記載のものが提供されている。   Conventionally, as chimneys that guide and dissipate exhaust gas from gas turbine engines and diesel engines that drive emergency generators installed in buildings, exhaust gas from boilers, exhaust gas from industrial waste incinerators, etc. 1 is provided.

前記特許文献１に記載の煙突は、図８に一部が示される四角筒形煙突ユニット１０の複数を、それらの軸線を鉛直に向けて（ただし、図８の煙突ユニットは軸線を水平に向けてある）上下に積層することにより構築される。各煙突ユニット１０は、投影平面形状が四角形で鉛直軸線を有する四角筒形断熱壁１１と、この四角筒形断熱壁１１の４つの外面を部分的に囲んで拘束する投影平面形状が四角形の四角形枠体１２と、を備える。   The chimney described in Patent Document 1 has a plurality of rectangular cylindrical chimney units 10 partially shown in FIG. 8 with their axes oriented vertically (however, the chimney unit of FIG. 8 has its axes oriented horizontally). It is constructed by stacking up and down. Each chimney unit 10 is a quadrangular rectangular heat insulating wall 11 having a quadrangular projection plane shape and a vertical axis, and a quadrangular quadrangular projection plane shape that partially surrounds and restrains the four outer surfaces of the rectangular cylindrical heat insulating wall 11. Frame 12.

四角筒形断熱壁１１は、４つのパネル１１ａ，１１ｂ，１１ｃ，１１ｄそれぞれの幅方向両端部どうしを、互いに係合して突き合わせた係合・突き合わせ構造で直角に組み合わせて四角筒形に構成されている。四角形枠体１２は、４つの隅角部を形成して鉛直方向にのびる４つのＬ形鋼１２Ａ，１２Ｂ，１２Ｃ，１２Ｄと、複数の水平材１２Ｅとを備える。   The rectangular cylindrical heat insulating wall 11 is formed into a rectangular cylindrical shape by combining the four panels 11a, 11b, 11c, and 11d in the width direction at both ends in an engagement / butting structure in which the panels are engaged with each other. ing. The quadrangular frame 12 includes four L-shaped steels 12A, 12B, 12C, and 12D that form four corner portions and extend in the vertical direction, and a plurality of horizontal members 12E.

各Ｌ形鋼１２Ａ〜１２Ｄは、各２辺１２ａ，１２ａ、１２ｂ，１２ｂ、１２ｃ，１２ｃ、１２ｄ，１２ｄがなす内角を内向きにして、Ｌ形鋼１２Ａと１２Ｄが１つの対角線上で互いに対向し、Ｌ形鋼１２Ｂと１２Ｃが残る１つの対角線上で互いに対向して配置されて４つの隅角部を形成している。   Each of the L-shaped steels 12A to 12D has an inner angle formed by each of the two sides 12a, 12a, 12b, 12b, 12c, 12c, 12d, and 12d facing inward, and the L-shaped steels 12A and 12D face each other on one diagonal line The L-shaped steels 12B and 12C are arranged opposite to each other on one diagonal line to form four corners.

各水平材１２Ｅは、前側の一対のＬ形鋼１２Ａ，１２Ｂに上下（図８では斜め横）の間隔を隔てて水平に架け渡して溶接により接合され、後側の一対のＬ形鋼１２Ｃ，１２Ｄに上下（図８では斜め横）の間隔を隔てて水平に架け渡して溶接により接合されるとともに、左側の一対のＬ形鋼１２Ａ，１２Ｃに上下（図８では斜め横）の間隔を隔てて水平（図８では垂直）に架け渡して溶接により接合され、右側の一対のＬ形鋼１２Ｂ，１２Ｄに上下（図８では斜め横）の間隔を隔てて水平（図８では垂直）に架け渡して溶接により接合される。煙突ユニット１０の軸線方向両端部（図８では軸線方一端部）にフランジ１３が設けられる。フランジ１３は、直上と直下で互いに対向する煙突ユニットどうしの連結時に複数のボルト・ナットからなる締結手段（図示省略）により締結される。そのため、締結手段のボルトを挿通する複数のボルト孔１３ａを設けてある。   Each horizontal member 12E is horizontally welded to a pair of front L-shaped steels 12A and 12B with an interval in the vertical direction (obliquely horizontal in FIG. 8) and joined by welding, and a pair of rear L-shaped steels 12C and 12C, 12D is horizontally welded with an interval of up and down (obliquely horizontal in FIG. 8) and joined by welding, and the pair of left and right L-shaped steels 12A and 12C is vertically spaced (obliquely oblique in FIG. 8). Then, they are bridged horizontally (vertically in FIG. 8) and joined by welding, and horizontally (vertically in FIG. 8) with a pair of right and left L-shaped steels 12B and 12D spaced apart from each other vertically (obliquely in FIG. 8). Passed and joined by welding. Flange 13 is provided at both ends in the axial direction of chimney unit 10 (in FIG. 8, one end in the axial direction). The flange 13 is fastened by fastening means (not shown) including a plurality of bolts and nuts when the chimney units facing each other directly above and below are connected. Therefore, a plurality of bolt holes 13a through which the bolts of the fastening means are inserted are provided.

前記煙突ユニット１０は、四角形枠体１２を組み立て、この四角形枠体１２に四角筒形断熱壁１１を差し込む手順により製作される。ここで、四角形枠体１２への四角筒形断熱壁１１の差し込みを許容するために、四角形枠体１２の内法を四角筒形断熱壁１１の外法に対して余裕をもたせて少し大きくしてある。そうすると、例えばディーゼルエンジンの排ガスのような脈動ガスが排気される場合、排気脈動の影響により四角筒形断熱壁１１の各パネル１１ａ，１１ｂ，１１ｃ，１１ｄに撓みが生じてカンカンといった高い雑音を発する。   The chimney unit 10 is manufactured by assembling a rectangular frame 12 and inserting a rectangular cylindrical heat insulating wall 11 into the rectangular frame 12. Here, in order to allow the insertion of the rectangular tubular insulating wall 11 into the rectangular frame 12, the inner method of the rectangular frame 12 is made slightly larger with a margin than the outer method of the rectangular cylindrical insulating wall 11. It is. Then, for example, when a pulsating gas such as exhaust gas from a diesel engine is exhausted, the panels 11a, 11b, 11c, and 11d of the rectangular cylindrical heat insulating wall 11 are bent due to the influence of the exhaust pulsation, and a high noise such as a can is generated. .

一方、四角形枠体１２の水平材１２Ｅは、Ｌ形鋼１２Ａ〜１２Ｄに対してそれぞれ溶接により接合されているので溶接箇所が多い。よって、四角形枠体１２の製作に長時間を要し製作コストが高くなり、延いては各煙突ユニット１０のコストが増す。   On the other hand, since the horizontal member 12E of the rectangular frame 12 is joined to the L-shaped steels 12A to 12D by welding, there are many welded portions. Therefore, it takes a long time to manufacture the quadrangular frame 12, which increases the manufacturing cost, and consequently increases the cost of each chimney unit 10.

他方、煙突ユニット１０は、前述の手順により工場で製作され、必要数量の煙突ユニット１０が、例えば大型トラックなどの運搬手段により煙突構築現場に運び込まれる。ところが、各煙突ユニット１０は嵩が高いので運搬手段１台当たりの煙突ユニット１０の積載数が制限される。そのため、必要数量の煙突ユニット１０を現場に運び込むには、運搬手段の使用台数の増量や大型化などが必要になり、それだけ運搬コストが高くなる。   On the other hand, the chimney unit 10 is manufactured in the factory according to the above-described procedure, and a required quantity of the chimney unit 10 is carried to the chimney construction site by a transportation means such as a large truck. However, since each chimney unit 10 is bulky, the number of stacks of the chimney units 10 per transport means is limited. Therefore, in order to carry the required quantity of chimney units 10 to the site, it is necessary to increase the number of transport means used, increase the size, etc., and the transport cost increases accordingly.

Step 1: Place the first frame portion horizontally with the outer surface of the other side of each of the pair of left and right L-shaped steels of the first frame portion facing upward.
Step 2: The front heat insulation wall is horizontally overlapped on the first frame portion, and the first frame portion and the front heat insulation wall are matched on the projection plane.

The structure can be manufactured by assembling the processes 1 to 6.

このような構成であると、四角形枠体の内法を四角筒形断熱壁の外法に対して余裕をもたせて大きくする必要がなくなり、四角筒形断熱壁の４つの外面を四角形枠体により隙間なく部分的に囲んで拘束することが可能となる。これにより、たとえディーゼルエンジンの排ガスのような脈動ガスが排気されても、四角筒形断熱壁の前後の断熱壁および左右の断熱壁それぞれの排気脈動の影響による撓みが抑制され、カンカンといった高い雑音を防止できる。   With such a configuration, there is no need to enlarge the inner method of the rectangular frame body with a margin with respect to the outer method of the rectangular cylindrical heat insulating wall, and the four outer surfaces of the rectangular cylindrical heat insulating wall are formed by the rectangular frame body. It becomes possible to enclose and restrain partly without a gap. As a result, even if pulsating gas such as exhaust gas from a diesel engine is exhausted, bending due to the influence of the exhaust pulsation on the front and rear insulating walls and the left and right insulating walls of the square cylindrical insulating wall is suppressed, and high noise such as canning Can be prevented.

煙突ユニットが、前記各パーツの工程１〜工程６による組み立てで製作できる構成であることにより、突ユニットの製作数量に相当する各パーツを組み立て前段の嵩の低い分解状態で工場から現場に運び込み、ここで組み立てて各煙突ユニットを製作することも可能となる。そのため、トラックなどの運搬手段の小型化や使用台数の低減などが可能となって運搬コストを削減できる。   Since the chimney unit can be manufactured by assembling the parts according to steps 1 to 6, each part corresponding to the production quantity of the protruding unit is brought from the factory to the site in a disassembled state with a low bulk before assembly. It is also possible to produce each chimney unit by assembling here. As a result, the transportation means such as trucks can be reduced in size and the number of units used can be reduced, and the transportation cost can be reduced.

前記第３枠部は、締結手段により各第２水平材を第１枠部と第２枠部それぞれの左側Ｌ形鋼の一方の辺の外面に接合して構成され、前記第４枠部は、締結手段により各第２水平材を第１枠部と第２枠部それぞれの右側Ｌ形鋼の一方の辺の外面に接合して構成される。これによると、第３，第４枠部構成のための溶接作業が不要になり、それに相当して、四角形枠体のトータル溶接箇所が大幅に削減され、四角形枠体の製作時間が短縮されて製作容易になり、製作コストを削減できる。   The third frame part is configured by joining each second horizontal member to the outer surface of one side of the left L-shaped steel of each of the first frame part and the second frame part by fastening means, and the fourth frame part is The second horizontal member is joined to the outer surface of one side of the right L-shaped steel of each of the first frame portion and the second frame portion by the fastening means. According to this, the welding work for the 3rd and 4th frame part composition becomes unnecessary, and correspondingly, the total welding location of the rectangular frame is greatly reduced, and the production time of the rectangular frame is shortened. Manufacture becomes easy and the manufacturing cost can be reduced.

前記四角筒形断熱壁の前断熱壁、後断熱壁、左断熱壁および右断熱壁は、それぞれケイ酸カルシウムのパネルで構成されている。これによれば、四角筒形断熱壁３は硬質で高い剛性が得られるので、肉厚を薄く設定して軽量化を図っても高剛性が確保されて、丈夫な煙突ユニットの製作に寄与するとともに、優れた断熱効果を発揮することが可能となる。   The front heat insulation wall, the rear heat insulation wall, the left heat insulation wall, and the right heat insulation wall of the rectangular tubular heat insulation wall are each composed of a calcium silicate panel. According to this, since the rectangular cylindrical heat insulating wall 3 is hard and has high rigidity, high rigidity is ensured even if the wall thickness is set thin to reduce the weight, contributing to the production of a durable chimney unit. At the same time, an excellent heat insulating effect can be exhibited.

前記第１，第２枠部それぞれの各第１水平材および第３，第４枠部それぞれの各第２水平材はＬ形鋼からなる。これによると、第１〜第４枠部それぞれの剛性は、平鋼からなる第１，第２水平材が備わる構成の第１，第２枠部の剛性よりも高められて、丈夫な煙突ユニット１Ａ，１Ｂ，１Ｃの製作を可能にする。   Each first horizontal member of each of the first and second frame parts and each second horizontal member of each of the third and fourth frame parts are made of L-shaped steel. According to this, the rigidity of each of the first to fourth frame parts is higher than the rigidity of the first and second frame parts having the first and second horizontal members made of flat steel, and is a durable chimney unit. 1A, 1B, 1C can be manufactured.

本考案に係る煙突によれば、各煙突ユニットは、四角形枠体の内法を四角筒形断熱壁の外法に対して余裕をもたせて大きくする必要がなくなり、四角筒形断熱壁の４つの外面を四角形枠体により隙間なく部分的に囲んで拘束することが可能となるので、たとえディーゼルエンジンの排ガスのような脈動ガスが排気されても、四角筒形断熱壁の前後の断熱壁および左右の断熱壁それぞれの排気脈動の影響による撓みが抑制され、カンカンといった高い雑音を防止できる。また、煙突ユニットの製作数量に相当する各パーツを、組み立て前段の嵩の低い分解状態で工場から現場に運び込み、ここで各煙突ユニットを製作することもできるので、トラックなどの運搬手段の小型化や使用台数の低減などが可能となって運搬コストを削減できる。さらに、四角形枠体のトータル溶接箇所が大幅に削減され、四角形枠体の製作時間が短縮されて製作容易になり、製作コストを削減できる。   According to the chimney according to the present invention, each chimney unit does not need to have a large inner size of the quadrangular frame with a margin with respect to the outer method of the square cylindrical heat insulating wall. Since the outer surface can be partially enclosed and constrained by a rectangular frame body, even if pulsating gas such as exhaust gas from a diesel engine is exhausted, the insulation walls before and after the rectangular tubular insulation wall The bend caused by the exhaust pulsation of each of the heat insulating walls is suppressed, and high noise such as canning can be prevented. In addition, each part corresponding to the production quantity of the chimney unit can be brought from the factory to the site in a disassembled state with low bulk before assembly, and each chimney unit can be produced here, so the transportation means such as trucks can be downsized. It is possible to reduce the number of units used and the transportation cost. Furthermore, the total welding location of the quadrangular frame is greatly reduced, the production time of the quadrangular frame is shortened and the production is facilitated, and the production cost can be reduced.

このように、各煙突ユニット１Ａ，１Ｂ，１Ｃは、第１枠部４０、第２枠部４１、前断熱壁３０、後断熱壁３１、左断熱壁３２、右断熱壁３３および第３枠部４２，第４枠部４３構成用の複数の第２水平材４０Ｙなどの各パーツを、前記工程１〜工程６による組み立てで製作できるように構成されているので、四角形枠体４の内法を四角筒形断熱壁３の外法に対して余裕をもたせて大きくする必要がなくなり、四角筒形断熱壁３の４つの外面３ａ〜３ｄを四角形枠体４により隙間なく部分的に囲んで拘束することが可能となる。これにより、たとえディーゼルエンジンの排ガスのような脈動ガスが排気されても、四角筒形断熱壁３の前後の断熱壁３０，３１および左右の断熱壁３２，３３それぞれの排気脈動の影響による撓みが抑制され、カンカンといった高い雑音を防止できる。   Thus, each chimney unit 1A, 1B, 1C includes the first frame part 40, the second frame part 41, the front heat insulation wall 30, the rear heat insulation wall 31, the left heat insulation wall 32, the right heat insulation wall 33 and the third frame part. 42, because the parts such as a plurality of second horizontal members 40Y for the construction of the fourth frame portion 43 can be manufactured by the assembly according to the steps 1 to 6, the inner method of the rectangular frame 4 is determined. It is no longer necessary to provide a large space with respect to the outer method of the rectangular cylindrical heat insulating wall 3, and the four outer surfaces 3 a to 3 d of the rectangular cylindrical heat insulating wall 3 are partially surrounded and constrained by the rectangular frame 4 without any gaps. It becomes possible. As a result, even if pulsating gas such as exhaust gas from a diesel engine is exhausted, bending due to the influence of the exhaust pulsation on the front and rear insulating walls 30 and 31 and the left and right insulating walls 32 and 33 of the square cylindrical insulating wall 3 is caused. Suppressed and can prevent high noise.

各煙突ユニット１Ａ，１Ｂ，１Ｃが、前記各パーツの工程１〜工程６による組み立てで製作できる構成であることは、煙突ユニットの製作数量に相当する各パーツを組み立て前段の嵩の低い分解状態で工場から現場に運び込み、ここで組み立てて各煙突ユニットを製作することも可能となる。そのため、トラックなどの運搬手段の小型化や使用台数の低減などが可能となって運搬コストを削減できる。   The fact that each chimney unit 1A, 1B, 1C can be manufactured by assembling the parts according to steps 1 to 6 means that each part corresponding to the production quantity of the chimney unit is in a disassembled state with a low bulk at the pre-assembly stage. It is also possible to carry it from the factory to the site and assemble it here to produce each chimney unit. As a result, the transportation means such as trucks can be reduced in size and the number of units used can be reduced, and the transportation cost can be reduced.

第３枠部４２は、締結手段５により各第２水平材４０Ｙを第１枠部４０と第２枠部４１それぞれの左側Ｌ形鋼４０Ａ，４１Ａの一方の辺４０ａ１，４１ａ１の外面に接合して構成され、第４枠部４３は、締結手段５により各第２水平材４０Ｙを第１枠部４０と第２枠部４１それぞれの右側Ｌ形鋼４０Ｂ，４１Ｂの一方の辺４０ｂ１，４１ｂ１の外面に接合して構成されているので、第３，第４枠部４２，４３構成のための溶接作業が不要になり、それに相当して、四角形枠体４のトータル溶接箇所が大幅に削減され、四角形枠体４の製作時間が短縮されて製作容易になり製作コストを削減できる。   The third frame portion 42 joins each second horizontal member 40Y to the outer surface of one side 40a1, 41a1 of the left L-shaped steel 40A, 41A of each of the first frame portion 40 and the second frame portion 41 by the fastening means 5. The fourth frame portion 43 is formed by the fastening means 5 so that each of the second horizontal members 40Y is formed on one side 40b1 and 41b1 of the right side L-shaped steels 40B and 41B of the first frame portion 40 and the second frame portion 41, respectively. Since it is configured to be joined to the outer surface, the welding work for configuring the third and fourth frame portions 42 and 43 is not required, and correspondingly, the total welding location of the rectangular frame 4 is greatly reduced. The production time of the quadrangular frame 4 is shortened, making the production easier and reducing the production cost.

四角筒形断熱壁３の前断熱壁３０、後断熱壁３１、左断熱壁３２おび右断熱壁３３は、それぞれケイ酸カルシウムのパネルで構成されているので、四角筒形断熱壁３は硬質で高い剛性が得られる。そのため、肉厚を薄く設定して軽量化を図っても高剛性が確保されて、丈夫な煙突ユニット１Ａ，１Ｂ，１Ｃの製作に寄与するとともに、優れた断熱効果を発揮することが可能となる。   Since the front heat insulation wall 30, the rear heat insulation wall 31, the left heat insulation wall 32, and the right heat insulation wall 33 of the square cylindrical heat insulation wall 3 are each made of a calcium silicate panel, the square cylindrical heat insulation wall 3 is hard. High rigidity is obtained. Therefore, even if the wall thickness is set to be thin and high weight is achieved, high rigidity is ensured, contributing to the production of durable chimney units 1A, 1B, and 1C, and exhibiting an excellent heat insulating effect. .

第１，第２枠部４０，４１それぞれの各第１水平材４０Ｘおよび第３，第４枠部４２，４３それぞれの各第２水平材４０ＹはＬ形鋼からなるので。第１〜第４枠部４０〜４３それぞれの剛性は、平鋼からなる第１，第２水平材４０Ｘ，４０Ｙが備わる構成の第１，第２枠部の剛性よりも高められて、丈夫な煙突ユニット１Ａ，１Ｂ，１Ｃの製作を可能にする。   Each first horizontal member 40X of each of the first and second frame portions 40, 41 and each second horizontal member 40Y of each of the third and fourth frame portions 42, 43 are made of L-shaped steel. The rigidity of each of the first to fourth frame parts 40 to 43 is higher than the rigidity of the first and second frame parts having the first and second horizontal members 40X and 40Y made of flat steel and is strong. The chimney units 1A, 1B, 1C can be manufactured.

本考案に係る煙突１は、前記実施形態のみに限定されるものではなく、その趣旨および技術思想を逸脱しない範囲であれば、構造変形が可能である。   The chimney 1 according to the present invention is not limited to the above-described embodiment, and can be structurally modified without departing from the spirit and technical idea thereof.

本考案の煙突は、非常用発電機を駆動するガスタービンエンジンやディーゼルエンジンの排ガス，ボイラーの排ガス或いは産業廃棄物焼却炉の排ガスなどを屋外に放散させる煙突として有用である。   The chimney of the present invention is useful as a chimney that diffuses the exhaust gas of a gas turbine engine or a diesel engine that drives an emergency generator, the exhaust gas of a boiler, the exhaust gas of an industrial waste incinerator or the like to the outside.
