　本例では、反応塔１０の底部１４側から上部１２側への高さ方向を＋ｚ方向とする。また、高さ方向とは反対の方向を－ｚ方向とする。なお、高さ方向に平行な方向は、「±」を用いずに単にｚ方向と記載する。本例において、便宜的に、＋ｚ方向を「上」または「上方」と称し、－ｚ方向を「下」または「下方」と称する場合がある。ｚ方向は、船舶の床面に垂直な方向であってよいし、地面に垂直な方向であってもよい。ただし、ｚ方向はこれらの方向の例に限定されない。他の例において、ｚ方向は地面に平行な方向であってもよい。ｘおよびｙ方向は、互いに垂直である。ｚ方向は、ｘおよびｙ方向において構成される平面に対して垂直な方向である。本例において、ｘ、ｙおよびｚ方向は、右手系を構成する。 In this example, the height direction from the bottom 14 side to the top 12 side of the reaction tower 10 is defined as the + z direction. Also, the direction opposite to the height direction is taken as the −z direction. The direction parallel to the height direction is simply referred to as the z direction without using “±”. In this example, for convenience, the + z direction may be referred to as “up” or “upward”, and the −z direction may be referred to as “down” or “downward”. The z direction may be a direction perpendicular to the floor of the ship or a direction perpendicular to the ground. However, the z direction is not limited to the examples of these directions. In another example, the z direction may be a direction parallel to the ground. The x and y directions are perpendicular to each other. The z direction is a direction perpendicular to the plane configured in the x and y directions. In this example, the x, y and z directions constitute a right-handed system.
　本例の反応塔１０は、上部外筒３０、中部外筒４０および下部外筒８０を有する。下部外筒８０は、中部外筒４０よりも反応塔１０の底部１４側に位置する。下部外筒８０は、側面に排ガス導入口１６を有し、底部１４に排水導出部１７を有する。排ガス導入口１６は、排ガス導入管が下部外筒８０と接続する領域である。排ガス導入管は、船舶のエンジン等から排出された排ガスを反応塔１０に導入する流路である。本例では、紙面奥の位置に設けられた排ガス導入口１６を破線により示す。排ガスは、排ガス導入口１６から反応塔１０の内部へ導入される。排ガスは、反応塔１０の内部で＋ｚ方向に旋回上昇してよい。排ガスは、反応塔１０の内部空間を＋ｚ方向に直線的に上昇するよりも内部空間を旋回する方が気液接触の確率が高くなるので、より効率的に洗浄される。 The reaction tower 10 of this example has an upper outer cylinder 30, a middle outer cylinder 40 and a lower outer cylinder 80. The lower outer cylinder 80 is located closer to the bottom 14 side of the reaction tower 10 than the middle outer cylinder 40. The lower outer cylinder 80 has the exhaust gas inlet 16 on the side surface and the drainage outlet 17 on the bottom part 14. The exhaust gas inlet 16 is an area where the exhaust gas inlet pipe is connected to the lower outer cylinder 80. The exhaust gas introduction pipe is a flow path for introducing exhaust gas discharged from a ship engine or the like into the reaction tower 10. In this example, the exhaust gas inlet 16 provided at a position in the back of the drawing is indicated by a broken line. The exhaust gas is introduced into the reaction tower 10 from the exhaust gas inlet 16. The exhaust gas may swirl up in the + z direction inside the reaction tower 10. The exhaust gas is washed more efficiently because the probability of gas-liquid contact is higher when swirling the internal space than when rising linearly in the + z direction in the internal space of the reaction tower 10.
　本例において、下部外筒８０の外形には、Ｕ字ボルト８２‐２が設けられる。Ｕ字ボルト８２‐２の湾曲部は、下部外筒８０に接触してよい。Ｕ字ボルト８２‐２の長手部は、側面９０に固定された台部９４‐２に固定される。これにより、下部外筒８０は、側面９０に固定される。 In this example, a U-shaped bolt 82-2 is provided on the outer shape of the lower outer cylinder 80. The curved portion of the U-shaped bolt 82-2 may contact the lower outer cylinder 80. The longitudinal part of the U-shaped bolt 82-2 is fixed to a base part 94-2 fixed to the side surface 90. Thereby, the lower outer cylinder 80 is fixed to the side surface 90.
　反応塔１０の底部１４近傍は、反応塔１０の内部で噴射された後に落下した液体を一時的に貯留する排水貯留部として機能してよい。排水導出部１７は、下部外筒８０の底部１４よりもさらに－ｚ方向に突出してよい。底部１４近傍に貯留された液体は、最終的に排水導出部１７から排水部８４へ排出されてよい。 The vicinity of the bottom 14 of the reaction tower 10 may function as a drainage storage part for temporarily storing the liquid that has fallen after being jetted inside the reaction tower 10. The drainage outlet 17 may protrude further in the −z direction than the bottom 14 of the lower outer cylinder 80. The liquid stored near the bottom 14 may be finally discharged from the drainage outlet 17 to the drainage 84.
　中部外筒４０は、第１の分割体５０と第２の分割体６０とを有する。本例の第１の分割体５０は、第２の分割体６０の上方に位置する。本例の第２の分割体６０は、第１の分割体５０の内径よりも小さな外径を有する。本例の第１の分割体５０は、＋ｚ方向の端部領域に位置する固定フランジ部５２と、－ｚ方向の端部領域位置する移動フランジ部５４とを有する。移動フランジ部５４は、第１のフランジ部の一例である。また、本例の第２の分割体６０は、－ｚ方向の端部領域位置する移動フランジ部６４を有する。移動フランジ部６４は、第２のフランジ部の一例である。 The middle outer cylinder 40 has a first divided body 50 and a second divided body 60. The first divided body 50 in this example is located above the second divided body 60. The second divided body 60 of this example has an outer diameter smaller than the inner diameter of the first divided body 50. The first divided body 50 of this example includes a fixed flange portion 52 located in the end region in the + z direction and a moving flange portion 54 located in the end region in the −z direction. The moving flange portion 54 is an example of a first flange portion. In addition, the second divided body 60 of the present example includes a moving flange portion 64 positioned in the end region in the −z direction. The moving flange portion 64 is an example of a second flange portion.
　移動機構７０は、第１の分割体５０および第２の分割体６０のいずれかをｚ方向に移動する機能を有する。移動機構７０を利用することにより、第２の分割体６０のｚ方向位置を固定した場合に、第１の分割体５０を－ｚ方向にスライドさせることができる。さらに、第１の分割体５０のｚ方向位置を固定した場合に、第２の分割体６０を＋ｚ方向にスライドさせることができる。ただし、図１においては、移動機構７０は、第１の分割体５０の移動フランジ部５４と第２の分割体６０の移動フランジ部６４とのｚ方向の位置を固定している。 The moving mechanism 70 has a function of moving either the first divided body 50 or the second divided body 60 in the z direction. By using the moving mechanism 70, when the z-direction position of the second divided body 60 is fixed, the first divided body 50 can be slid in the −z direction. Furthermore, when the z-direction position of the first divided body 50 is fixed, the second divided body 60 can be slid in the + z direction. However, in FIG. 1, the moving mechanism 70 fixes the position in the z direction between the moving flange portion 54 of the first divided body 50 and the moving flange portion 64 of the second divided body 60.
　本例では、第１の分割体５０および第２の分割体６０をｚ方向にスライドさせて開閉するので、中部外筒４０の側面の一部を外側に回転させて開閉する場合と比較して、開閉時に必要な船内空間を減らすことができる。加えて、本例においては、中部外筒４０の側面の一部を外側に回転させて開閉する場合と比較して密封封止が容易であるので、より気密性を高くすることができる。 In this example, since the first divided body 50 and the second divided body 60 are opened and closed by sliding in the z direction, compared with a case where a part of the side surface of the middle outer cylinder 40 is rotated outward to open and close. The space required for opening and closing can be reduced. In addition, in this example, airtightness can be further increased because sealing and sealing are easier than in the case where a part of the side surface of the middle outer tube 40 is rotated outward to open and close.
　本例の排ガス処理装置１００は、封止リング５８を有する。封止リング５８は、第２の分割体６０の外径と、移動フランジ部５４と、後述の封止部材５６とに接触する。本例の封止リング５８は、金属製のリングである。本例の封止リング５８は、後述の封止部材５６を圧接する。これにより、第１の分割体５０と第２の分割体６０との間のすき間を封止してよい。なお、本例において、封止リング５８は、固定具５１により移動フランジ部５４に固定される。 The exhaust gas treatment apparatus 100 of this example has a sealing ring 58. The sealing ring 58 contacts the outer diameter of the second divided body 60, the moving flange portion 54, and a sealing member 56 described later. The sealing ring 58 of this example is a metal ring. The sealing ring 58 of this example presses a sealing member 56 described later. Thereby, the gap between the first divided body 50 and the second divided body 60 may be sealed. In this example, the sealing ring 58 is fixed to the moving flange portion 54 by the fixing tool 51.
　上部外筒３０は、中部外筒４０上に設けられる。上部外筒３０の外形には、Ｕ字ボルト８２‐１が設けられる。Ｕ字ボルト８２‐１の長手部は、台部９４‐１に固定される。これにより、下部外筒８０は、側面９０に対して固定される。上部外筒３０および下部外筒８０に設けられたＵ字ボルト８２により、反応塔１０は船舶の側面９０に対して固定される。 The upper outer cylinder 30 is provided on the middle outer cylinder 40. A U-shaped bolt 82-1 is provided on the outer shape of the upper outer cylinder 30. The longitudinal part of the U-shaped bolt 82-1 is fixed to the base part 94-1. Thereby, the lower outer cylinder 80 is fixed to the side surface 90. The reaction tower 10 is fixed to the side surface 90 of the ship by U-shaped bolts 82 provided on the upper outer cylinder 30 and the lower outer cylinder 80.
　レデューサ部２２は、上部外筒３０上に設けられる。本例において、レデューサ部２２の－ｚ方向の端部における大径部は、上部外筒３０に接続する。また、本例のレデューサ部２２の＋ｚ方向の端部における小径部は、煙道部２０に接続する。本例のレデューサ部２２のｘ‐ｙ平面における中心軸は、中部外筒４０の中心軸と一致する。レデューサ部２２は、ｘ‐ｙ平面における半径が＋ｚ方向に進むにつれて徐々に減少する円錐台形状の内部空間を有する。これにより、煙道部２０と上部外筒３０とが直接接続する場合と比較して、排ガス処理装置１００における圧力損失を低減する機能を有する。 The reducer unit 22 is provided on the upper outer cylinder 30. In this example, the large diameter portion at the end in the −z direction of the reducer portion 22 is connected to the upper outer cylinder 30. In addition, the small diameter portion at the end in the + z direction of the reducer portion 22 of this example is connected to the flue portion 20. The central axis in the xy plane of the reducer portion 22 of this example coincides with the central axis of the middle outer cylinder 40. The reducer portion 22 has a truncated cone-shaped internal space that gradually decreases as the radius in the xy plane advances in the + z direction. Thereby, compared with the case where the flue part 20 and the upper outer cylinder 30 connect directly, it has the function to reduce the pressure loss in the exhaust gas processing apparatus 100.
　レデューサ部２２は、煙道部２０に接続する。煙道部２０は、船舶の外まで延伸してよい。排ガス処理装置１００により洗浄処理された排ガスは、煙道部２０を通って船舶外へ排出されてよい。 The reducer unit 22 is connected to the flue unit 20. The flue section 20 may extend outside the ship. The exhaust gas cleaned by the exhaust gas processing apparatus 100 may be discharged outside the ship through the flue portion 20.
　本例の反応塔１０は、底部１４から上部１２までの高さ方向の長さが３［ｍ］であり、内径が７００［ｍｍ］である。また、本例のレデューサ部２２は高さ方向の長さが６５４［ｍｍ］であり、小径部の内径は４２０［ｍｍ］である。 The reaction tower 10 of this example has a length in the height direction from the bottom 14 to the top 12 of 3 [m] and an inner diameter of 700 [mm]. Further, the reducer portion 22 of this example has a length in the height direction of 654 [mm], and the inner diameter of the small diameter portion is 420 [mm].
　図２は、図１のＡ‐Ａ'断面の上面図である。なお、図２においては、反応塔１０の内部空間に位置する構造物を省略している。図２においては、移動フランジ部５４上の移動機構７０および固定具５１を示す。本例の排ガス処理装置１００は、３つの移動機構７０を有する。本例の移動機構７０は、中部外筒４０の中心軸１１から＋ｙ方向に伸びる半径軸を時計回りに±６０度回転した位置および１８０度回転した位置に設けられる。なお、他の例において、排ガス処理装置１００は、４つ以上の移動機構７０を有してもよい。図２において、移動機構７０は、棒部材７２およびナット部７７を有する。本例のナット部７７は、六角柱の外形を有する。 FIG. 2 is a top view of the AA ′ cross section of FIG. In FIG. 2, structures located in the internal space of the reaction tower 10 are omitted. In FIG. 2, the moving mechanism 70 and the fixture 51 on the moving flange portion 54 are shown. The exhaust gas treatment apparatus 100 of this example has three moving mechanisms 70. The moving mechanism 70 of the present example is provided at a position where a radial axis extending in the + y direction from the central axis 11 of the middle outer tube 40 is rotated ± 60 degrees clockwise and 180 degrees. In another example, the exhaust gas treatment apparatus 100 may include four or more moving mechanisms 70. In FIG. 2, the moving mechanism 70 has a bar member 72 and a nut portion 77. The nut portion 77 of this example has an outer shape of a hexagonal column.
　本例の排ガス処理装置１００は、３つの固定具５１を有する。本例の固定具５１は、中心軸１１から＋ｙ方向に伸びる半径軸の位置および当該半径軸を時計回りに±１２０度回転した位置に設けられる。本例においては、固定具５１および移動機構７０を中心軸１１における異なる半径軸上に設けることにより、固定具５１および移動機構７０を同じ半径軸上に設ける場合と比較して、固定具５１の取り付けおよび取り外しならびに移動機構７０の操作がより容易になる。なお、他の例において、排ガス処理装置１００は、４つ以上の固定具５１を有してもよい。 The exhaust gas treatment apparatus 100 of this example has three fixtures 51. The fixture 51 of this example is provided at a position of a radial axis extending in the + y direction from the central axis 11 and a position obtained by rotating the radial axis by ± 120 degrees clockwise. In this example, by providing the fixing tool 51 and the moving mechanism 70 on different radial axes in the central axis 11, compared to the case where the fixing tool 51 and the moving mechanism 70 are provided on the same radial axis, Attachment and removal and operation of the moving mechanism 70 become easier. In another example, the exhaust gas treatment apparatus 100 may have four or more fixtures 51.
　図３は、排ガス処理装置１００の断面を示す図である。ただし、理解を容易にすることを目的として、幹管２４、枝管２５、噴射部２６、液体導入部２８およびバッフル２９は、断面ではなく側面を示す。反応塔１０は、底部１４側から＋ｚ方向に延伸する内部空間１５を有する。 FIG. 3 is a view showing a cross section of the exhaust gas treatment apparatus 100. However, for the purpose of facilitating understanding, the trunk tube 24, the branch tube 25, the injection unit 26, the liquid introduction unit 28, and the baffle 29 show side surfaces instead of cross sections. The reaction tower 10 has an internal space 15 extending in the + z direction from the bottom 14 side.
　排ガス処理装置１００は、下部外筒８０の内部に、液体導入部２８およびバッフル２９を有する。本例の液体導入部２８は、下部外筒８０の底部１４近傍において下部外筒８０の側面から内部に導入される。本例の液体導入部２８は、ｘ‐ｚ平面においてＬ字形状に屈曲した管である。液体導入部２８には、反応塔１０の外部からポンプ等を用いて、海水、湖水、川水またはアルカリ性の液体が導入される。本例の液体は、排ガスを処理する液体である。液体導入部２８と幹管２４とは流体連結されており、液体導入部２８に導入された液体は幹管２４へ供給される。 The exhaust gas treatment apparatus 100 has a liquid introduction part 28 and a baffle 29 inside the lower outer cylinder 80. The liquid introducing portion 28 of this example is introduced into the inside from the side surface of the lower outer cylinder 80 in the vicinity of the bottom 14 of the lower outer cylinder 80. The liquid introducing portion 28 in this example is a tube bent into an L shape in the xz plane. Seawater, lake water, river water, or alkaline liquid is introduced into the liquid introduction unit 28 from the outside of the reaction tower 10 using a pump or the like. The liquid in this example is a liquid for treating exhaust gas. The liquid introduction unit 28 and the trunk tube 24 are fluidly connected, and the liquid introduced into the liquid introduction unit 28 is supplied to the trunk tube 24.
　本例のバッフル２９は、液体導入部２８に接して設置される。バッフル２９は、ｘ‐ｙ平面に平行な平面を有してよい。本例のバッフル２９は、液体導入部２８が通ることができる貫通開口を有する円板である。バッフル２９は、排ガス導入口１６よりも底部１４側に設けられる。バッフル２９は、排ガスが導入される領域と排水を貯留する領域とに、下部外筒８０を区切る機能を有してよい。 The baffle 29 in this example is installed in contact with the liquid introduction unit 28. The baffle 29 may have a plane parallel to the xy plane. The baffle 29 of this example is a disk having a through opening through which the liquid introduction part 28 can pass. The baffle 29 is provided closer to the bottom 14 than the exhaust gas inlet 16. The baffle 29 may have a function of dividing the lower outer cylinder 80 into a region where exhaust gas is introduced and a region where drainage is stored.
　排ガス処理装置１００は、反応塔１０の内部空間１５において、幹管２４、複数の枝管２５および複数の噴射部２６を有する。本例の幹管２４は、反応塔１０の内部空間１５において高さ方向に延伸する。本例の幹管２４は、中部外筒４０と同じ高さ位置に設けられる。幹管２４は、液体導入部２８から供給された液体を高さ方向に運搬可能である。幹管２４には複数の枝管２５が接続される。幹管２４から複数の枝管２５へ液体が供給されるよう、幹管２４と複数の枝管２５とは流体連結されている。 The exhaust gas treatment apparatus 100 includes a main pipe 24, a plurality of branch pipes 25, and a plurality of injection units 26 in the internal space 15 of the reaction tower 10. The trunk tube 24 of this example extends in the height direction in the internal space 15 of the reaction tower 10. The trunk tube 24 of this example is provided at the same height as the middle outer tube 40. The trunk tube 24 can transport the liquid supplied from the liquid introduction part 28 in the height direction. A plurality of branch pipes 25 are connected to the trunk pipe 24. The stem tube 24 and the plurality of branch tubes 25 are fluidly connected so that liquid is supplied from the stem tube 24 to the plurality of branch tubes 25.
　本例の幹管２４は、高さ方向範囲において分割することできない１本の管である。ただし、他の例において、幹管２４は、高さ方向において二以上に分割可能であってもよい。一例において、幹管２４の高さ方向における長さの半分の位置で、幹管２４は二つに分割可能であってよい。これにより、第１の分割体５０を開いた場合には、幹管２４の上半分を反応塔１０から取り出すことができる。さらに、第２の分割体６０を開いた場合には、幹管２４の下半分を反応塔１０から取り出すことができる。 The trunk tube 24 in this example is a single tube that cannot be divided in the height direction range. However, in another example, the trunk tube 24 may be divisible into two or more in the height direction. In one example, the trunk tube 24 may be split into two at a position half the length in the height direction of the trunk tube 24. Thereby, when the 1st division body 50 is opened, the upper half of the trunk tube 24 can be taken out from the reaction tower 10. Further, when the second divided body 60 is opened, the lower half of the trunk tube 24 can be taken out from the reaction tower 10.
　複数の枝管２５は、幹管２４の外壁から中部外筒４０の内壁に向けて延伸して設けられる。枝管２５の長手方向の一端は、幹管２４に溶接されてよい。本例では、同じ高さ位置に４つの枝管２５‐Ａ、枝管２５‐Ｂ、枝管２５‐Ｃおよび枝管２５‐Ｄが設けられる。本例において、４つの枝管２５‐Ａから枝管２５‐Ｄは、幹管２４を上面視した場合に略十字形状を形成する。なお、図３においては紙面奥に位置する枝管２５‐Ｄは図示されていない。 The plurality of branch pipes 25 are provided to extend from the outer wall of the trunk pipe 24 toward the inner wall of the middle outer cylinder 40. One end in the longitudinal direction of the branch pipe 25 may be welded to the trunk pipe 24. In this example, four branch pipes 25-A, a branch pipe 25-B, a branch pipe 25-C, and a branch pipe 25-D are provided at the same height position. In this example, the four branch pipes 25-A to 25-D form a substantially cross shape when the trunk pipe 24 is viewed from above. In FIG. 3, the branch pipe 25-D located in the back of the drawing is not shown.
　本例において複数の枝管２５は、高さ方向において重なるよう設けられる。本例において、複数の枝管２５‐１Ａから２５‐ｎＡは、高さ方向において一定間隔で離間して各々異なる高さ位置に設けられる。なお、ｎは２以上の自然数である。本例においては、ｎ＝７である。枝管２５の高さ方向におけるピッチは０．３［ｍ］であってよい。本例において、枝管２５‐１Ｂから枝管２５‐ｎＢも、各々異なる高さ位置に所定のピッチだけ離間して設けられる。枝管２５‐１Ｃから枝管２５‐ｎＣおよび枝管２５‐１Ｄから枝管２５‐ｎＤも同様である。 In this example, the plurality of branch pipes 25 are provided so as to overlap in the height direction. In this example, the plurality of branch pipes 25-1A to 25-nA are provided at different height positions spaced apart from each other at regular intervals in the height direction. Note that n is a natural number of 2 or more. In this example, n = 7. The pitch in the height direction of the branch pipe 25 may be 0.3 [m]. In this example, the branch pipes 25-1B to 25-nB are also provided at different height positions with a predetermined pitch. The same applies to the branch pipe 25-1C to the branch pipe 25-nC and the branch pipe 25-1D to the branch pipe 25-nD.
　複数の枝管２５の各々は、噴射部２６を有する。本例では、１つの枝管２５は２つの噴射部２６を有する。なお、１つの枝管２５が有する噴射部２６の数は、２つに限定されず３つ以上であってもよい。噴射部２６は、ねじ込み手段により枝管２５に接続されてよく、溶接により枝管２５に接続されてもよい。 Each of the plurality of branch pipes 25 has an injection unit 26. In this example, one branch pipe 25 has two injection units 26. In addition, the number of the injection parts 26 which one branch pipe 25 has is not limited to two, Three or more may be sufficient. The injection unit 26 may be connected to the branch pipe 25 by screwing means, or may be connected to the branch pipe 25 by welding.
　噴射部２６は、幹管２４から供給される液体を反応塔１０の内部空間１５において噴射する。噴射された液体は、細かい水滴または霧状に変化する。噴射された液体と排ガスとを気液接触させることにより、排ガス中の硫黄酸化物等は液体に吸収される。これにより、排ガスを洗浄することができる。噴射部２６は、空円錐状に液体を噴射するスプレーノズルであってよい。本例では、×印を付した部分に、噴射部２６の噴射口が設けられる。 The injection unit 26 injects the liquid supplied from the trunk tube 24 in the internal space 15 of the reaction tower 10. The jetted liquid changes into a fine water droplet or mist. By bringing the injected liquid and exhaust gas into gas-liquid contact, sulfur oxides and the like in the exhaust gas are absorbed by the liquid. Thereby, exhaust gas can be washed. The ejection unit 26 may be a spray nozzle that ejects liquid in an empty cone shape. In this example, the injection port of the injection part 26 is provided in the part which attached | subjected x mark.
　本例の第１の分割体５０は、円筒状の側面の端部を移動フランジ部５４にはめ合わせることにより組み立てられる。具体的には、円筒状の側面の下部に位置する凸部を移動フランジ部５４の上面の凹部に嵌合させることにより、側面および移動フランジ部５４における円の中心を正確に位置合わせして組み立てる。当該組み立て方式は、一般的にインロー方式（即ち、凸部と凹部とのかみ合いによる組み立て方式）と呼ばれている。本例の第２の分割体６０も、インロー方式により組み立てられる。 The first divided body 50 of this example is assembled by fitting the end portion of the cylindrical side surface to the moving flange portion 54. Specifically, the convex portion located at the lower portion of the cylindrical side surface is fitted into the concave portion on the upper surface of the moving flange portion 54, and the side surface and the center of the circle in the moving flange portion 54 are accurately aligned and assembled. . The assembling method is generally called an inlay method (that is, an assembling method by engaging convex portions and concave portions). The second divided body 60 of this example is also assembled by the inlay method.
　本例の排ガス処理装置１００は、封止部材５６をさらに有する。本例の封止部材５６は、第２の分割体６０の外径と、移動フランジ部５４の底部１４側の面と、封止リング５８の内側の斜面５７とに接触する。なお、斜面５７は次図において符号と共に示す。本例の封止部材５６は、Ｏリングである。封止リング５８の内側の斜面５７が封止部材５６を圧接することにより、第１の分割体５０と第２の分割体６０との間のすき間を封止することができる。 The exhaust gas treatment apparatus 100 of this example further includes a sealing member 56. The sealing member 56 of this example is in contact with the outer diameter of the second divided body 60, the surface on the bottom 14 side of the moving flange portion 54, and the inclined surface 57 inside the sealing ring 58. In addition, the slope 57 is shown with a code | symbol in the following figure. The sealing member 56 in this example is an O-ring. The inclined surface 57 inside the sealing ring 58 presses the sealing member 56 so that the gap between the first divided body 50 and the second divided body 60 can be sealed.
　移動機構７０は、棒部材７２および駆動部７６を有する。１つの移動機構７０は、１つの棒部材７２と、棒部材７２の異なる位置にそれぞれ設けられた２つの駆動部７６とを有する。棒部材７２は、移動フランジ部５４と移動フランジ部６４とを連結する。駆動部７６は、第１の分割体５０および第２の分割体６０のいずれかをｚ方向に移動させる。本例において、駆動部７６‐１は、第１の分割体５０をｚ方向に移動させる。また、駆動部７６‐２は、第２の分割体６０をｚ方向に移動させる。 The moving mechanism 70 includes a bar member 72 and a drive unit 76. One moving mechanism 70 includes one bar member 72 and two drive units 76 provided at different positions of the bar member 72. The bar member 72 connects the moving flange portion 54 and the moving flange portion 64. The drive unit 76 moves either the first divided body 50 or the second divided body 60 in the z direction. In this example, the drive unit 76-1 moves the first divided body 50 in the z direction. In addition, the driving unit 76-2 moves the second divided body 60 in the z direction.
　上部外筒３０は、内部に液返しリング３５を有する。液返しリング３５は、上部外筒３０の内壁に接してリング状に設けられる。液返しリング３５は、霧状となった液体が排ガス処理装置１００の外に排出されることを防ぐ機能を有してよい。液返しリング３５は、リング上に滞留した液体が自重により下方に落下できる開口を有してよい。 The upper outer cylinder 30 has a liquid return ring 35 inside. The liquid return ring 35 is provided in a ring shape in contact with the inner wall of the upper outer cylinder 30. The liquid return ring 35 may have a function of preventing the atomized liquid from being discharged out of the exhaust gas treatment apparatus 100. The liquid return ring 35 may have an opening through which liquid staying on the ring can fall downward due to its own weight.
　図４は、第１実施形態における領域Ｂの拡大図である。図４は、中部外筒４０を閉じた状態を示す。中部外筒４０を閉じた状態においてｚ方向において連結される移動フランジ部５４と移動フランジ部６４とは、ともに－ｚ方向の端部領域に位置してよい。本例において、移動フランジ部５４は第１の分割体５０の最も下方に設けられ、移動フランジ部６４は第２の分割体６０の最も下方に設けられる。本例において、移動フランジ部５４の外径は、固定フランジ部５２の外径よりも長い。また、第２の分割体６０は、固定フランジ部を有せず、移動フランジ部６４のみを有する。移動フランジ部６４は、移動フランジ部５４の外径と同程度の長さの外径を有する。 FIG. 4 is an enlarged view of the region B in the first embodiment. FIG. 4 shows a state in which the middle outer cylinder 40 is closed. Both the moving flange portion 54 and the moving flange portion 64 that are coupled in the z direction when the middle outer tube 40 is closed may be located in the end region in the −z direction. In this example, the moving flange portion 54 is provided at the lowermost position of the first divided body 50, and the moving flange portion 64 is provided at the lowermost position of the second divided body 60. In this example, the outer diameter of the moving flange portion 54 is longer than the outer diameter of the fixed flange portion 52. Further, the second divided body 60 does not have a fixed flange portion but has only a moving flange portion 64. The moving flange portion 64 has an outer diameter that is approximately the same length as the outer diameter of the moving flange portion 54.
　本例において、固定フランジ部という用語は、常にその位置が固定されているフランジ部を意味しない。本例において、固定フランジ部５２は、第１の分割体５０が移動する際には移動してよい。本例において、固定フランジ部は、駆動部７６が位置する移動フランジ部とは異なるフランジ部であることを意味するに過ぎない。 In this example, the term “fixed flange portion” does not mean a flange portion whose position is always fixed. In this example, the fixed flange portion 52 may move when the first divided body 50 moves. In this example, the fixed flange portion only means that the flange portion is different from the moving flange portion where the drive portion 76 is located.
　本例において、棒部材７２のｚ方向における長さは、中部外筒４０を閉じた状態において、ｚ方向において連結された移動フランジ部５４と移動フランジ部６４との間の長さよりも長い。具体的には、中部外筒４０を閉じた状態において、本例の棒部材７２は、移動フランジ部５４よりも上に突出し、移動フランジ部６４よりも下に突出する。棒部材７２は、第２の分割体６０のｚ方向長さより長くてもよい。また、本例の棒部材７２は、２つのナット部７７のｚ方向長さ分だけ移動フランジ部５４よりも上に突出してよく、２つのナット部７７のｚ方向長さ分だけ移動フランジ部６４よりも下に突出してよい。 In this example, the length of the rod member 72 in the z direction is longer than the length between the moving flange portion 54 and the moving flange portion 64 connected in the z direction when the middle outer tube 40 is closed. Specifically, in a state where the middle outer tube 40 is closed, the rod member 72 of this example protrudes above the moving flange portion 54 and protrudes below the moving flange portion 64. The bar member 72 may be longer than the length of the second divided body 60 in the z direction. Further, the rod member 72 of this example may protrude above the moving flange portion 54 by the length of the two nut portions 77 in the z direction, and the moving flange portion 64 by the length of the two nut portions 77 in the z direction. May protrude below.
　本例の棒部材７２は、ねじ切りされた表面７３を有する。また、本例の駆動部７６は、複数のナット部７７を有する。本例の駆動部７６‐１は、固定用のナット部７７‐１および移動用のナット部７７‐２を有する。本例では、ねじ切りされた表面７３を有する棒部材７２と複数のナット部７７とにより移動機構７０を構成する。それゆえ、移動機構７０の構成を簡単にできる。 The rod member 72 of this example has a threaded surface 73. Further, the drive unit 76 of this example includes a plurality of nut portions 77. The drive unit 76-1 in this example includes a fixing nut portion 77-1 and a moving nut portion 77-2. In this example, a moving mechanism 70 is constituted by a bar member 72 having a threaded surface 73 and a plurality of nut portions 77. Therefore, the configuration of the moving mechanism 70 can be simplified.
　固定用のナット部７７‐１と移動用のナット部７７‐２とは、移動フランジ部５４を間に挟む。中部外筒４０を閉じた状態において、固定用のナット部７７‐１は移動フランジ部５４の上面に接触してよい。移動用のナット部７７‐２は、移動フランジ部５４に接触して、第１の分割体５０を下から支えることができる。移動用のナット部７７‐２は、棒部材７２においてｚ方向に移動可能である。固定具３１を外した後に移動用のナット部７７‐２を－ｚ方向に回転移動させることにより、第１の分割体５０を－ｚ方向に移動させることができる。なお、第１の分割体５０を－ｚ方向に移動させる際に、固定用のナット部７７‐１を外してもよい。また、なお、第１の分割体５０を－ｚ方向に移動させる際に、固定具５１、封止部材５６および封止リング５８は、中部外筒４０から外してよいし、中部外筒４０から外さずにそのままにしてもよい。 The fixing nut portion 77-1 and the moving nut portion 77-2 sandwich the moving flange portion 54 therebetween. In a state where the middle outer cylinder 40 is closed, the fixing nut portion 77-1 may contact the upper surface of the moving flange portion 54. The moving nut portion 77-2 can contact the moving flange portion 54 and support the first divided body 50 from below. The moving nut portion 77-2 is movable in the z direction on the bar member 72. The first divided body 50 can be moved in the -z direction by removing the fixing tool 31 and rotating the moving nut portion 77-2 in the -z direction. Note that the fixing nut portion 77-1 may be removed when the first divided body 50 is moved in the -z direction. Further, when the first divided body 50 is moved in the −z direction, the fixture 51, the sealing member 56, and the sealing ring 58 may be removed from the middle outer cylinder 40, or from the middle outer cylinder 40. You may leave it without removing it.
　また、本例の駆動部７６‐２は、固定用のナット部７７‐３および移動用のナット部７７‐４を有する。固定用のナット部７７‐３と移動用のナット部７７‐４とは、移動フランジ部６４を間に挟む。中部外筒４０を閉じた状態において、固定用のナット部７７‐３は移動フランジ部６４の上面に接触してよい。移動用のナット部７７‐４は、移動フランジ部６４に接触して、第２の分割体６０を下から支えることができる。移動用のナット部７７‐４は、棒部材７２においてｚ方向に移動可能である。固定具６１を外した後に移動用のナット部７７‐４を＋ｚ方向に回転移動させることにより、第２の分割体６０を＋ｚ方向に移動させることができる。なお、第２の分割体６０を＋ｚ方向に移動させる際には、固定用のナット部７７‐１を外す。また、なお、第２の分割体６０を＋ｚ方向に移動させる際に、固定具５１、封止部材５６および封止リング５８は、中部外筒４０から外してよいし、中部外筒４０から外さずにそのままにしてもよい。 Further, the drive unit 76-2 of this example includes a fixing nut portion 77-3 and a moving nut portion 77-4. The fixing nut portion 77-3 and the moving nut portion 77-4 sandwich the moving flange portion 64 therebetween. In a state where the middle outer tube 40 is closed, the fixing nut portion 77-3 may contact the upper surface of the moving flange portion 64. The moving nut portion 77-4 can contact the moving flange portion 64 and support the second divided body 60 from below. The moving nut portion 77-4 is movable in the z direction on the bar member 72. The second split body 60 can be moved in the + z direction by removing the fixture 61 and rotating the moving nut portion 77-4 in the + z direction. When the second divided body 60 is moved in the + z direction, the fixing nut portion 77-1 is removed. In addition, when the second divided body 60 is moved in the + z direction, the fixture 51, the sealing member 56, and the sealing ring 58 may be removed from the middle outer cylinder 40 or removed from the middle outer cylinder 40. It may be left as it is.
　これにより、排ガスを処理する位置に反応塔１０を設置した状態において、中部外筒４０の少なくとも一部はｚ方向に移動可能である。本例において、排ガスを処理する位置に反応塔１０を設置した状態とは、排ガス処理装置１００が上方において煙道部２０に接続し、かつ、下方において排水部８４に接続した状態をいう。本例においては、噴射部２６をメンテナンスする際に、クレーン等を用いて反応塔１０を取り外す必要が無いので、クレーンを設けるスペースおよびコストを削減することができる。また、クレーン等による作業を要しないので、その分メンテナンス作業時間を短縮することができる。 Thereby, in a state where the reaction tower 10 is installed at the position where the exhaust gas is treated, at least a part of the middle outer cylinder 40 is movable in the z direction. In this example, the state where the reaction tower 10 is installed at the position where the exhaust gas is treated refers to a state where the exhaust gas treatment device 100 is connected to the flue section 20 at the upper side and connected to the drainage section 84 at the lower side. In this example, when the injection unit 26 is maintained, it is not necessary to remove the reaction tower 10 using a crane or the like, so that the space and cost for installing the crane can be reduced. In addition, since no work by a crane or the like is required, maintenance work time can be shortened accordingly.
　図５Ａは、第１の分割体５０を－ｚ方向に移動した状態を示す図である。移動用のナット部７７‐２を－ｚ方向に最大限移動させることにより、第１の分割体５０に対応する高さ範囲に略対応する内部空間１５‐１が露出する。これにより作業者は、内部空間１５‐１に位置する噴射部２６をメンテナンスすることができる。本例においては、枝管２５‐１から枝管２５‐４まで（即ち、第１段目から第４段目まで）の噴射部２６をメンテナンスすることができる。なお、本例において、メンテナンスとは、噴射部２６の噴射性能を維持するために、噴射部２６を交換することおよび噴射部２６をクリーニングすること等の作業をいう。 FIG. 5A is a diagram showing a state in which the first divided body 50 is moved in the −z direction. By moving the moving nut portion 77-2 to the maximum in the −z direction, the internal space 15-1 substantially corresponding to the height range corresponding to the first divided body 50 is exposed. Thereby, the operator can maintain the injection part 26 located in the internal space 15-1. In this example, the injection unit 26 from the branch pipe 25-1 to the branch pipe 25-4 (that is, from the first stage to the fourth stage) can be maintained. In this example, maintenance refers to operations such as replacing the injection unit 26 and cleaning the injection unit 26 in order to maintain the injection performance of the injection unit 26.
　なお、移動用のナット部７７‐２を回転移動させる際には、３つの移動用のナット部７７‐２の内１つの移動用のナット部７７‐２だけを集中的に回転移動させずに、３つの移動用のナット部７７‐２をそれぞれ少しずつ回転移動させる方がよい。一例として、３つのナット部７７‐２をそれぞれ一回転ずつ回転移動させる。これにより、移動用のナット部７７‐２と棒部材７２との間に摩擦熱が発生して移動用のナット部７７‐２が棒部材７２に対して動かなくなること（かじり、または、焼き付き）を防止することができる。なお、反応塔１０はＵ字ボルト８２によりｚ方向の位置が固定されているので、第１の分割体５０を上部外筒３０から離間させても内部空間１５‐１の露出は維持される。 When rotating the moving nut part 77-2, only one moving nut part 77-2 of the three moving nut parts 77-2 is not rotatively moved. It is better to rotate and move the three moving nut portions 77-2 little by little. As an example, the three nut portions 77-2 are rotationally moved by one rotation each. As a result, frictional heat is generated between the moving nut portion 77-2 and the rod member 72, and the moving nut portion 77-2 does not move relative to the rod member 72 (galling or seizing). Can be prevented. In addition, since the position of the reaction tower 10 in the z direction is fixed by the U-shaped bolt 82, the exposure of the internal space 15-1 is maintained even if the first divided body 50 is separated from the upper outer cylinder 30.
　図５Ｂは、第２の分割体６０を＋ｚ方向に移動した状態を示す図である。本例においては、固定用のナット部７７‐３および移動用のナット部７７‐４を＋ｚ方向に最大限移動させることにより、第２の分割体６０に対応する高さ範囲に略対応する内部空間１５‐２が露出する。これにより作業者は、内部空間１５‐２に位置する噴射部２６をメンテナンスすることができる。本例においては、枝管２５‐５から枝管２５‐７まで（即ち、第５段目から第７段目まで）の噴射部２６をメンテナンスすることができる。 FIG. 5B is a diagram illustrating a state in which the second divided body 60 is moved in the + z direction. In this example, the fixing nut portion 77-3 and the moving nut portion 77-4 are moved to the maximum in the + z direction so as to substantially correspond to the height range corresponding to the second divided body 60. The space 15-2 is exposed. Thereby, the operator can maintain the injection part 26 located in the internal space 15-2. In this example, the injection unit 26 from the branch pipe 25-5 to the branch pipe 25-7 (that is, from the fifth stage to the seventh stage) can be maintained.
　図６は、第１実施形態の変形例を示す図である。本例の移動機構７０において、駆動部７６は、ボールブッシュ部７８を有する。また、棒部材７２は、ボールブッシュ部７８のボールを受けるスパイラル状の溝を表面７４に有する。係る点において、図１から図５Ａおよび図５Ｂの例と異なる。なお、一般的に、ボールブッシュはリニアブッシュと呼ばれる場合もある。 FIG. 6 is a diagram showing a modification of the first embodiment. In the moving mechanism 70 of this example, the drive unit 76 has a ball bushing 78. Further, the rod member 72 has a spiral groove on the surface 74 for receiving the ball of the ball bush portion 78. This is different from the examples of FIGS. 1 to 5A and 5B. In general, the ball bush may be called a linear bush.
　本例のボールブッシュ部７８‐１は、移動フランジ部５４に接触して、第１の分割体５０を支えることができる。また、本例のボールブッシュ部７８‐２は、移動フランジ部６４の上面に接触してよく、移動フランジ部５４および移動フランジ部６４間の距離を固定してよい。なお、他の例においては、ボールブッシュ部７８‐２が移動フランジ部６４の下面に接してよく、ボールブッシュ部７８‐２が第２の分割体６０を支えてもよい。また、本例のボールブッシュ部７８‐１およびボールブッシュ部７８‐２は、棒部材７２においてｚ方向に移動可能である。具体的には、ボールブッシュ部７８は、棒部材７２に対して回転することによりｚ方向に移動することができる。 The ball bushing portion 78-1 in this example can support the first divided body 50 by contacting the moving flange portion 54. Moreover, the ball bush part 78-2 of this example may contact the upper surface of the moving flange part 64, and the distance between the moving flange part 54 and the moving flange part 64 may be fixed. In another example, the ball bush portion 78-2 may contact the lower surface of the moving flange portion 64, and the ball bush portion 78-2 may support the second divided body 60. In addition, the ball bush portion 78-1 and the ball bush portion 78-2 in this example are movable in the z direction on the bar member 72. Specifically, the ball bush portion 78 can move in the z direction by rotating with respect to the rod member 72.
　ボールブッシュ部７８は、電動で回転移動する機構を有してよい。この場合、３つのボールブッシュ部７８は同時に同じピッチで移動することができる。これにより、ナット部７７の例と比較して、第１の分割体５０または第２の分割体６０を方向に正確に移動させることができる。また、ナット部７７の例と比較して、より短時間で第１の分割体５０または第２の分割体６０を移動させることができる。 The ball bushing 78 may have a mechanism that rotates electrically. In this case, the three ball bush portions 78 can move simultaneously at the same pitch. Thereby, compared with the example of the nut portion 77, the first divided body 50 or the second divided body 60 can be accurately moved in the direction. Moreover, compared with the example of the nut portion 77, the first divided body 50 or the second divided body 60 can be moved in a shorter time.
　図７は、第２の分割体６０の変形例を示す部分拡大図である。図７においては、理解を容易にするべく、幹管２４、枝管２５および噴射部２６を省略する。本例において、移動フランジ部６４が設けられた端部領域とは反対側の端部領域において、第２の分割体６０の内径６５の側面のｚ方向の長さは外径６６の側面のｚ方向の長さよりも長い。つまり、本例において、第２の分割体６０の＋ｚ方向の端部は、第１の分割体５０の内表面に対向する斜面６７を有する。図７の断面視図において、第２の分割体６０の内表面（つまり、内径６５の円筒）と斜面６７とは、３０度の角度を形成してよい。これにより、第１の分割体５０および第２の分割体６０は、斜面６７を設けない場合と比較して互いにスライドしやすくなる。なお、図７の例を第１実施形態およびその変形例に適用してよい。 FIG. 7 is a partially enlarged view showing a modification of the second divided body 60. In FIG. 7, the trunk tube 24, the branch tube 25, and the injection unit 26 are omitted for easy understanding. In this example, the length in the z direction of the side surface of the inner diameter 65 of the second divided body 60 is z in the side surface of the outer diameter 66 in the end region opposite to the end region where the moving flange portion 64 is provided. Longer than the direction length. That is, in this example, the + z-direction end portion of the second divided body 60 has a slope 67 that faces the inner surface of the first divided body 50. In the cross-sectional view of FIG. 7, the inner surface of the second divided body 60 (that is, the cylinder having the inner diameter 65) and the inclined surface 67 may form an angle of 30 degrees. Thereby, the 1st division body 50 and the 2nd division body 60 become easy to mutually slide compared with the case where the slope 67 is not provided. Note that the example of FIG. 7 may be applied to the first embodiment and its modifications.
　図８は、第２実施形態における領域Ｂの拡大図である。本例において、第２の分割体６０は第１の分割体５０よりも＋ｚ方向に設けられる。これに伴い、中部外筒４０を閉じた状態においてｚ方向において連結される移動フランジ部５４と移動フランジ部６４とは、ともに＋ｚ方向の端部領域に位置する。本例において、移動フランジ部５４は第１の分割体５０の最も上方に設けられ、移動フランジ部６４は第２の分割体６０の最も上方に設けられる。つまり、本例は、第１実施形態の中部外筒４０を上下逆さまにした構成に相当する。 FIG. 8 is an enlarged view of the region B in the second embodiment. In this example, the second divided body 60 is provided in the + z direction with respect to the first divided body 50. Accordingly, the moving flange portion 54 and the moving flange portion 64 that are coupled in the z direction when the middle outer cylinder 40 is closed are both located in the end region in the + z direction. In this example, the moving flange portion 54 is provided at the uppermost position of the first divided body 50, and the moving flange portion 64 is provided at the uppermost position of the second divided body 60. That is, this example corresponds to a configuration in which the middle outer cylinder 40 of the first embodiment is turned upside down.
　本例では、第１の分割体５０の内径よりも小さな外径６６を有する第２の分割体６０を、第１の分割体５０よりも上に設ける。これにより、第１実施形態と比較して、内部空間１５の液体が中部外筒４０から漏れにくいという点が有利である。なお、本例においても、封止リング５８は、第２の分割体６０の外径６６と、移動フランジ部５４と、封止部材５６とに接触する。また、なお、本例においても、図６におけるボールブッシュ部７８の例および図７における斜面６７を設ける例の一以上を適用してよい。 In this example, the second divided body 60 having an outer diameter 66 smaller than the inner diameter of the first divided body 50 is provided above the first divided body 50. Thereby, compared with 1st Embodiment, the point that the liquid of the internal space 15 cannot leak easily from the center part outer cylinder 40 is advantageous. Also in this example, the sealing ring 58 contacts the outer diameter 66 of the second divided body 60, the moving flange portion 54, and the sealing member 56. Also in this example, one or more of the example of the ball bush portion 78 in FIG. 6 and the example of providing the slope 67 in FIG. 7 may be applied.
　図９は、第３実施形態における領域Ｂの拡大図である。本例の第１の分割体５０は、第１実施形態における第１の分割体５０を上下逆さまにした構成に相当する。本例において、中部外筒４０を閉じた状態において、移動フランジ部５４と移動フランジ部６４とは、ｚ方向において連結される。特に、本例では、移動フランジ部５４が＋ｚ方向の端部領域に位置し、移動フランジ部６４が－ｚ方向の端部領域に位置する。また、本例では、棒部材７２のｚ方向における長さは、中部外筒４０を閉じた状態において、ｚ方向において連結された移動フランジ部５４と移動フランジ部５４との間の長さよりも長い。 FIG. 9 is an enlarged view of the region B in the third embodiment. The 1st division body 50 of this example is corresponded to the structure which turned the 1st division body 50 in 1st Embodiment upside down. In this example, the moving flange portion 54 and the moving flange portion 64 are connected in the z direction in a state where the middle outer cylinder 40 is closed. In particular, in this example, the moving flange portion 54 is located in the end region in the + z direction, and the moving flange portion 64 is located in the end region in the −z direction. In this example, the length of the rod member 72 in the z direction is longer than the length between the moving flange portion 54 and the moving flange portion 54 connected in the z direction in a state where the middle outer tube 40 is closed. .
　本例の棒部材７２は、第１および第２実施形態の棒部材７２よりも長い距離に渡って、第１の分割体５０および第２の分割体６０を支持する。それゆえ、本例においては、第１および第２実施形態と比較して、中部外筒４０の機械的安定性が高いという点が有利である。 The rod member 72 of this example supports the first divided body 50 and the second divided body 60 over a longer distance than the rod member 72 of the first and second embodiments. Therefore, in this example, it is advantageous that the mechanical stability of the middle outer cylinder 40 is higher than in the first and second embodiments.
　なお、本例の排ガス処理装置１００は、第２の分割体６０の外径６６と、移動フランジ部５４とは反対方向の端部領域に位置する第３のフランジ部としての固定フランジ部５２とに少なくとも接触する封止部材５６を有する。封止リング５８は、第２の分割体６０の外径６６と、固定フランジ部５２と、封止部材５６とに接触する。なお、固定フランジ部５２は、第１の分割体５０において移動フランジ部５４とは反対方向の端部領域に位置する。また、なお、本例においても、図６におけるボールブッシュ部７８の例および図７における斜面６７を設ける例の一以上を適用してよい。 The exhaust gas treatment apparatus 100 of this example includes an outer diameter 66 of the second divided body 60 and a fixed flange portion 52 as a third flange portion located in an end region in the direction opposite to the moving flange portion 54. A sealing member 56 at least in contact therewith. The sealing ring 58 contacts the outer diameter 66 of the second divided body 60, the fixed flange portion 52, and the sealing member 56. Note that the fixed flange portion 52 is located in the end region in the direction opposite to the moving flange portion 54 in the first divided body 50. Also in this example, one or more of the example of the ball bush portion 78 in FIG. 6 and the example of providing the slope 67 in FIG. 7 may be applied.
　図１０は、第４実施形態における領域Ｂの拡大図である。本例では、中部外筒４０を閉じた状態において、移動フランジ部５４が－ｚ方向の端部領域に位置し、移動フランジ部６４が＋ｚ方向の端部領域に位置する。つまり、本例は、第３実施形態の中部外筒４０を上下逆さまにした構成に相当する。本例においても、第１および第２実施形態と比較して、中部外筒４０の機械的安定性が高い。なお、本例においても、封止リング５８は、第２の分割体６０の外径６６と、固定フランジ部５２と、封止部材５６とに接触する。また、なお、本例においても、図６におけるボールブッシュ部７８の例および図７における斜面６７を設ける例の一以上を適用してよい。 FIG. 10 is an enlarged view of the region B in the fourth embodiment. In this example, in a state where the middle outer cylinder 40 is closed, the moving flange portion 54 is located in the end region in the −z direction, and the moving flange portion 64 is located in the end region in the + z direction. That is, this example corresponds to a configuration in which the middle outer cylinder 40 of the third embodiment is turned upside down. Also in this example, the mechanical stability of the middle outer cylinder 40 is high compared to the first and second embodiments. Also in this example, the sealing ring 58 contacts the outer diameter 66 of the second divided body 60, the fixed flange portion 52, and the sealing member 56. Also in this example, one or more of the example of the ball bush portion 78 in FIG. 6 and the example of providing the slope 67 in FIG. 7 may be applied.
　図１１は、排ガス処理装置１００のメンテナンス方法２００を示す図である。メンテナンス時においては、エンジン等から反応塔１０への排ガスの供給を停止する。加えて、幹管２４から噴射部２６への液体の供給も停止する。 FIG. 11 is a diagram showing a maintenance method 200 of the exhaust gas treatment apparatus 100. During maintenance, the supply of exhaust gas from the engine or the like to the reaction tower 10 is stopped. In addition, the supply of liquid from the trunk tube 24 to the ejection unit 26 is also stopped.
　メンテナンス方法２００は上述の第１および第３実施形態に適用してよい。本例では、排ガスを処理する位置に反応塔１０を設置した状態において、各段階を実行することができる。本例では、第１の分割体５０と同じ高さ位置の噴射部２６をメンテナンスするか否かを最初に判断する（Ｓ１０）。Ｓ１０においてＹＥＳの場合Ｓ２０に進み、Ｓ１０においてＮＯの場合Ｓ１２に進む。 The maintenance method 200 may be applied to the first and third embodiments described above. In this example, each stage can be executed in a state where the reaction tower 10 is installed at a position where the exhaust gas is processed. In this example, it is first determined whether or not to maintain the injection unit 26 at the same height as the first divided body 50 (S10). If YES in S10, the process proceeds to S20. If NO in S10, the process proceeds to S12.
　Ｓ２０は、固定具３１、固定具５１、封止部材５６および封止リング５８を反応塔１０から取り外す段階である。また、Ｓ２０において、ナット部７７を用いる例においては、固定用ナット部７７‐３を＋ｚ方向に移動させてよい。なお、ナット部７７を用いる例においては、Ｓ２０において固定用のナット部７７‐１を反応塔１０から取り外してもよい。 S20 is a stage in which the fixture 31, the fixture 51, the sealing member 56, and the sealing ring 58 are removed from the reaction tower 10. In S20, in the example using the nut portion 77, the fixing nut portion 77-3 may be moved in the + z direction. In the example using the nut portion 77, the fixing nut portion 77-1 may be removed from the reaction tower 10 in S20.
　Ｓ３０は、反応塔１０の中部外筒４０の少なくとも一部をｚ方向に平行に移動する段階である。第１および第３実施形態においては、第１の分割体５０を－ｚ方向に移動させる。 S30 is a stage in which at least a part of the middle outer cylinder 40 of the reaction tower 10 is moved in parallel to the z direction. In the first and third embodiments, the first divided body 50 is moved in the −z direction.
　Ｓ４０は、第１の分割体５０に略対応する内部空間１５を露出して、反応塔１０の内部に位置する噴射部２６をメンテナンスする段階である。内部空間１５が露出されるので、作業者は容易に噴射部２６にアクセスすることができる。 S40 is a stage in which the internal space 15 substantially corresponding to the first divided body 50 is exposed and the injection unit 26 located inside the reaction tower 10 is maintained. Since the internal space 15 is exposed, the operator can easily access the injection unit 26.
　Ｓ５０は、Ｓ３０とは逆方向に、第１の分割体５０を平行移動させる段階である。本例においては、Ｓ３０において－ｚ方向に移動させた第１の分割体５０を＋ｚ方向に移動させる段階である。これにより、中部外筒４０を閉じる。Ｓ６０は、固定具３１を取り付ける段階である。これにより、第１の分割体５０を上部外筒３０に固定する。 S50 is a stage in which the first divided body 50 is translated in the opposite direction to S30. In this example, the first divided body 50 moved in the −z direction in S30 is moved in the + z direction. Thereby, the middle outer cylinder 40 is closed. S60 is a stage in which the fixture 31 is attached. Thereby, the first divided body 50 is fixed to the upper outer cylinder 30.
　次にＳ１２に進む。Ｓ１２は、第２の分割体６０と同じ高さ位置の噴射部２６をメンテナンスするか否かを判断する段階である。Ｓ１２においてＹＥＳの場合、Ｓ２２に進む。Ｓ１２においてＮＯの場合、Ｓ７０に進む。 Next, proceed to S12. S12 is a stage in which it is determined whether or not the injection unit 26 at the same height as the second divided body 60 is to be maintained. If YES in S12, the process proceeds to S22. If NO in S12, the process proceeds to S70.
　Ｓ２２からＳ６２の一連の段階は、Ｓ２０からＳ６０の一連の段階とほぼ同様であるので、相違点のみを述べる。Ｓ２２では、固定具３１に代えて固定具６１を取り外す。また、ナット部７７を用いる例においては、Ｓ２２において固定用のナット部７７‐３を移動させる。係る点において、Ｓ２２はＳ２０と異なる。 The series of steps from S22 to S62 is almost the same as the series of steps from S20 to S60, so only the differences will be described. In S22, the fixture 61 is removed instead of the fixture 31. Moreover, in the example using the nut part 77, the nut part 77-3 for fixation is moved in S22. In this regard, S22 is different from S20.
　Ｓ３２からＳ５２の一連の段階は、第１の分割体５０に代えて第２の分割体６０を移動させる。係る点において、Ｓ３２からＳ５２の一連の段階は、Ｓ３０からＳ５０の一連の段階と異なる。Ｓ６２は、固定具６１を取り付ける段階である。これにより、第２の分割体６０を下部外筒８０に固定する。 In a series of steps S32 to S52, the second divided body 60 is moved instead of the first divided body 50. In this respect, the series of steps from S32 to S52 is different from the series of steps from S30 to S50. S62 is a stage in which the fixture 61 is attached. Thereby, the second divided body 60 is fixed to the lower outer cylinder 80.
　次にＳ１０に戻る。第１の分割体５０と同じ高さ位置の噴射部２６を既にメンテナンスした場合には、Ｓ１０においてＮＯを選択して、Ｓ１２に進んでよい。第２の分割体６０と同じ高さ位置の噴射部２６を既にメンテナンスした場合には、Ｓ１２においてＮＯを選択して、Ｓ７０に進んでよい。 Next, return to S10. When the injection unit 26 at the same height as the first divided body 50 has already been maintained, NO may be selected in S10 and the process may proceed to S12. When the injection unit 26 at the same height as the second divided body 60 has already been maintained, NO may be selected in S12 and the process may proceed to S70.
　Ｓ７０は、固定具５１、封止部材５６および封止リング５８を反応塔１０に取りつける段階である。Ｓ７０の後、メンテナンス方法２００のフローは終了する。 S70 is a stage in which the fixture 51, the sealing member 56, and the sealing ring 58 are attached to the reaction tower 10. After S70, the flow of the maintenance method 200 ends.
　なお、本例のメンテナンス方法２００においては、第１の分割体５０をメンテナンスするか否かを最初に判断するが、第２の分割体６０をメンテナンスするか否かを最初に判断してもよい。つまり、Ｓ１０からＳ６０の一連の段階を、Ｓ１２からＳ６２の一連の段階と入れ替えてもよい。 In the maintenance method 200 of this example, it is first determined whether or not the first divided body 50 is to be maintained, but it may be determined first whether or not the second divided body 60 is to be maintained. . That is, the series of steps S10 to S60 may be replaced with the series of steps S12 to S62.
　図１２は、排ガス処理装置１００のメンテナンス方法２１０を示す図である。メンテナンス方法２１０は上述の第２および第４実施形態に適用してよい。図１２のメンテナンス方法２１０は、図１１のメンテナンス方法２００とほぼ同じである。相違点は、次の（１）から（３）である。これら以外の重複する説明は省略する。 FIG. 12 is a diagram showing a maintenance method 210 of the exhaust gas treatment apparatus 100. The maintenance method 210 may be applied to the second and fourth embodiments described above. The maintenance method 210 in FIG. 12 is almost the same as the maintenance method 200 in FIG. Differences are the following (1) to (3). A duplicate description other than these is omitted.
　（１）図１２のＳ１４からＳ６４における一連の段階が第２の分割体６０を対象としているのに対して、図１１のＳ１０からＳ６０における一連の段階が第１の分割体５０を対象としている。（２）図１２のＳ１６からＳ６６における一連の段階が第１の分割体５０を対象としているのに対して、図１１のＳ１２からＳ６２における一連の段階が第２の分割体６０を対象としている。（３）Ｓ７２において、封止部材５６、封止リング５８および固定具５１を反応塔１０に取り付ける。 (1) While the series of steps in S14 to S64 in FIG. 12 is for the second divided body 60, the series of steps in S10 to S60 in FIG. 11 is for the first divided body 50. . (2) A series of steps from S16 to S66 in FIG. 12 is directed to the first divided body 50, whereas a series of steps from S12 to S62 in FIG. 11 is directed to the second divided body 60. . (3) In S72, the sealing member 56, the sealing ring 58, and the fixture 51 are attached to the reaction tower 10.
　図１３Ａは、第５実施形態における領域Ｂの拡大図である。第５から第７実施形態は、移動機構７０により中部外筒４０の一部をスライド開閉する上述の例の代替例である。第５から第７実施形態において、中部外筒４０の一部は伸縮性筒部を有してよい。 FIG. 13A is an enlarged view of a region B in the fifth embodiment. The fifth to seventh embodiments are alternative examples of the above-described example in which a part of the middle outer cylinder 40 is slid open and closed by the moving mechanism 70. In the fifth to seventh embodiments, a part of the middle outer cylinder 40 may have a stretchable cylinder part.
　本例の中部外筒４０は、上部分割体１５０と下部分割体１６０とを有する。本例の上部分割体１５０は、上部フランジ部１５２と、下部フランジ部１５４と、上部フランジ部１５２と下部フランジ部１５４との間のベローズ（ｂｅｌｌｏｗｓ）部１５６とを有する。ベローズ部１５６は、ｚ方向に伸縮性筒部である。また、本例の下部分割体１６０は、上部フランジ部１６２と、下部フランジ部１６４とを有する。下部フランジ部１５４と上部フランジ部１６２とは、固定具１５１により固定される。下部フランジ部１６４の下部と下部外筒８０の上部とは、固定具１６１により固定される。 The middle outer cylinder 40 in this example has an upper divided body 150 and a lower divided body 160. The upper divided body 150 of this example includes an upper flange portion 152, a lower flange portion 154, and a bellows portion 156 between the upper flange portion 152 and the lower flange portion 154. The bellows part 156 is an elastic cylinder part in the z direction. In addition, the lower divided body 160 of this example includes an upper flange portion 162 and a lower flange portion 164. The lower flange portion 154 and the upper flange portion 162 are fixed by a fixture 151. The lower part of the lower flange part 164 and the upper part of the lower outer cylinder 80 are fixed by a fixture 161.
　図１３Ｂは、ベローズ部１５６を開いた状態を示す図である。ベローズ部１５６は、リング状の薄肉金属板の内縁と外縁とを交互に溶接してつなぎ合わせた伸縮性筒部である。固定具３１を取り外すことにより、作業者は手動でベローズ部１５６を開けることができる。これにより、第１の分割体５０に対応する高さ範囲に略対応する内部空間１５‐１が露出する。したがって、作業者は、上部分割体１５０と同じ高さ位置の噴射部２６をメンテナンスすることができる。本例においては、枝管２５‐１から枝管２５‐４まで（即ち、第１段目から第４段目まで）の噴射部２６をメンテナンスすることができる。ベローズ部１５６を用いることにより、第１から第４実施形態と比較して上部分割体１５０の開閉がより容易になる点が有利である。 FIG. 13B is a diagram showing a state in which the bellows portion 156 is opened. The bellows part 156 is a stretchable cylinder part in which inner and outer edges of a ring-shaped thin metal plate are alternately welded and joined. By removing the fixing tool 31, the operator can manually open the bellows part 156. As a result, the internal space 15-1 that substantially corresponds to the height range corresponding to the first divided body 50 is exposed. Therefore, the operator can maintain the ejection unit 26 at the same height as the upper divided body 150. In this example, the injection unit 26 from the branch pipe 25-1 to the branch pipe 25-4 (that is, from the first stage to the fourth stage) can be maintained. The use of the bellows part 156 is advantageous in that the upper divided body 150 can be opened and closed more easily than in the first to fourth embodiments.
　図１４は、図１３ＡのＣ‐Ｃ'断面の上面図である。なお、図１４においては、内部空間１５の構造を省略している。図１４においては、下部フランジ部１５４上の固定具１５１を示す。本例の排ガス処理装置１００は、６つの固定具１５１を有する。本例の固定具１５１は、中部外筒４０の中心軸１１から＋ｙ方向に伸びる半径軸を時計回りに±６０度回転した位置、±１２０度回転した位置、ならびに、０度および１８０度回転した位置に設けられる。 FIG. 14 is a top view of the CC ′ cross section of FIG. 13A. In FIG. 14, the structure of the internal space 15 is omitted. In FIG. 14, the fixture 151 on the lower flange part 154 is shown. The exhaust gas treatment apparatus 100 of this example has six fixtures 151. The fixing device 151 of the present example rotates a radial axis extending in the + y direction from the central axis 11 of the middle outer cylinder 40 by ± 60 degrees clockwise, a position rotated ± 120 degrees, and 0 degrees and 180 degrees. Provided in position.
　図１５は、第６実施形態における領域Ｂの拡大図である。本例においては、下部分割体１６０が、上部フランジ部１６２と下部フランジ部１６４との間のベローズ部１６６を有する。固定具１５１を取り外すことにより、作業者は手動でベローズ部１６６を開けることができる。これにより、下部分割体１６０と同じ高さ位置の噴射部２６をメンテナンスすることができる。本例においては、第１から第４実施形態と比較して下部分割体１６０の開閉がより容易になる点が有利である。 FIG. 15 is an enlarged view of the region B in the sixth embodiment. In this example, the lower divided body 160 has a bellows portion 166 between the upper flange portion 162 and the lower flange portion 164. By removing the fixing tool 151, the operator can manually open the bellows portion 166. Thereby, the injection unit 26 at the same height as the lower divided body 160 can be maintained. In this example, it is advantageous that the lower divided body 160 can be opened and closed more easily than in the first to fourth embodiments.
　図１６は、第７実施形態における領域Ｂの拡大図である。本例においては、上部フランジ部１７２および下部フランジ部１７４を除く中部外筒４０の全体がベローズ部１７６である。本例では固定具３１を取り外すことにより、作業者は手動でベローズ部１７６を開けることができる。これにより、中部外筒４０と同じ高さ位置の噴射部２６をメンテナンスすることができる。本例においては、第１から第４実施形態と比較して、中部外筒４０全体の開閉がより容易になる点が有利である。 FIG. 16 is an enlarged view of the region B in the seventh embodiment. In this example, the entire middle outer cylinder 40 excluding the upper flange portion 172 and the lower flange portion 174 is a bellows portion 176. In this example, the operator can open the bellows part 176 manually by removing the fixture 31. Thereby, the injection unit 26 at the same height as the middle outer cylinder 40 can be maintained. In this example, compared to the first to fourth embodiments, it is advantageous in that the opening and closing of the entire middle outer tube 40 becomes easier.
