The umbrella-shaped member 3 (gas dispersion means) is arranged in a convex state with an interval. The umbrella-shaped member 3 is connected to and fixed to the inner peripheral surface of the umbrella-shaped lid portion 2c by a linear member 3a in the vicinity of the edge.

冷却室本体２の側周部２ｄの内周面には、その内周面の上端から前記ガス排出口２ｂの上側まで、大小２枚のフィン４ａ、４ｂが２重螺旋状に形成されている。大フィン４ａと小フィン４ｂとは、互いに一定間隔おきに螺旋を形成しており、どちらのフィン４ａ、４ｂも、内方に向かって下方に傾斜している。   On the inner peripheral surface of the side peripheral portion 2d of the cooling chamber body 2, two large and small fins 4a and 4b are formed in a double spiral shape from the upper end of the inner peripheral surface to the upper side of the gas discharge port 2b. . The large fins 4a and the small fins 4b form a spiral at regular intervals, and both the fins 4a and 4b are inclined downward inward.

冷却室本体２の底部２ｅの内周面はすり鉢状に形成されており、その中央には、下に突出する円筒状の突出部２ｆが形成されている。この突出部２ｆの内部空間の下面は、冷却室本体２の底部２ｅと同様にすり鉢状に形成されており、その下端には後述する凝縮水を排出するための凝縮水排出口２ｇが設けられている。   The inner peripheral surface of the bottom 2e of the cooling chamber main body 2 is formed in a mortar shape, and a cylindrical protruding portion 2f protruding downward is formed at the center thereof.

Water is introduced and circulated and discharged from the outlet 2i. Thereby, the inner peripheral surface of the cooling chamber C and the fins 4a and 4b are cooled, and the cooling chamber C itself is also indirectly cooled.

冷却室本体２内部には、大小２つの螺旋状の液体導入管５ａ、５ｂが配設されている。これら液体導入管５ａ、５ｂの螺旋は、前記フィン４ａ、４ｂと同方向に螺旋が回旋しており、大液体導入管５ａの内部に小液体導入管５ｂが装入されると共に、両導入管５ａ、５ｂの軸心が冷却室本体２の軸心と一致するように配置されている。この液体導入管５ａ、５ｂは、板状部材５ｃによって傘状蓋部２ｃの内周面と接続されて固定されている大小２つの筒状部材５ｄ、５ｅに巻回されている。これら筒状部材５ｄ、５ｅはパンチングメタルで形成されている。両導入管５ａ、５ｂの下端には、冷却室本体２の傘状蓋部２ｃを貫通する液体送入管５ａ1、５ｂ1が接続されていると共に、両導入管５ａ、５ｂの上端には、冷却室本体２の底部２ｅ及び突出部２ｆを貫通する液体送出管５ａ2、５ｂ2が接続されている。これにより、液体送入管５ａ1、５ｂ1を介して冷却室本体２外部から液体導入管５ａ、５ｂに対して水が送入され、冷却室Ｃの冷却に使用された水は液体送出管５ａ2、５ｂ2を介して冷却室本体２外に送出される。 Inside the cooling chamber main body 2, two large and small spiral liquid introduction pipes 5a and 5b are arranged. The spirals of these liquid introduction pipes 5a and 5b rotate in the same direction as the fins 4a and 4b, and the small liquid introduction pipe 5b is inserted into the large liquid introduction pipe 5a, and both the introduction pipes The shaft centers of 5a and 5b are arranged so as to coincide with the shaft center of the cooling chamber main body 2. The liquid introduction pipes 5a and 5b are wound around two large and small cylindrical members 5d and 5e that are connected and fixed to the inner peripheral surface of the umbrella-shaped lid 2c by a plate-like member 5c. These cylindrical members 5d and 5e are formed of punching metal. Both inlet tube 5a, the lower end of 5b, together with the cone-shaped lid liquid inlet tube 5a 1 2c through the, 5b 1 of the cooling chamber body 2 is connected, both inlet pipe 5a, the upper end of 5b The liquid delivery pipes 5a 2 and 5b 2 that pass through the bottom 2e and the protrusion 2f of the cooling chamber main body 2 are connected to each other. As a result, water is fed from the outside of the cooling chamber main body 2 to the liquid introducing pipes 5a and 5b via the liquid feeding pipes 5a 1 and 5b 1 , and the water used for cooling the cooling chamber C is the liquid delivery pipe. It is sent out of the cooling chamber body 2 through 5a 2 and 5b 2 .

さらに、冷却室本体２内部には、その軸心方向に延びる５本の冷却管６ａ〜６ｅが配設されている。この冷却管６ａ〜６ｅには、液体を噴霧するための微細孔（図示せず）が多数形成されている。冷却管６ａは冷却室本体２の軸心上に配置され、冷却管６ｂ、６ｃは大液体導入管５ａと小液体導入管５ｂとの間に配置され、冷却管６ｄ、６ｅはフィン４ａを貫通して配置されている。冷却管６ａ〜６ｅには、冷却室本体２の傘状蓋部２ｃを貫通する冷却管用送入管６1と、その冷却管用送入管６1に接続され、水平方向に延びる分岐管６2とを介して冷却用の水が送られる。これにより、冷却管用送入管６1及び分岐管６2を介して冷却室本体２外部から冷却管６ａ〜６ｅに対して水が送入され、その微細孔から噴霧されて冷却室Ｃを直接的に冷却した水は、後述する凝縮水排出口２ｇから排出される。 Furthermore, five cooling pipes 6a to 6e extending in the axial direction are disposed inside the cooling chamber body 2. Many cooling holes (not shown) for spraying the liquid are formed in the cooling pipes 6a to 6e. The cooling pipe 6a is arranged on the axis of the cooling chamber body 2, the cooling pipes 6b and 6c are arranged between the large liquid introduction pipe 5a and the small liquid introduction pipe 5b, and the cooling pipes 6d and 6e pass through the fin 4a. Are arranged. The cooling tube 6a~6e is cooling chamber and umbrella lid pipe 6 1 2c feed cooling tubes extending through the main body 2, is connected to the pipe 61 feeding the cooling pipe, the branch pipe 6 2 extending in the horizontal direction Cooling water is sent via Thus, water is fed from the cooling chamber body 2 outside via the cooling pipe inlet tube 61 and the branch pipe 6 2 with respect to the cooling tube 6a to 6e, the cooling chamber C directly sprayed from the micropores The cooled water is discharged from a condensed water discharge port 2g described later.

冷却室本体２内の下部であって、前記ガス排出口２ｂの側方には、凝縮水分離器７が配設されている。この凝縮水分離器７は、図２に示すように、円筒状の内壁部７ａと、その内壁部７ａよりも径が大きい円筒状に形成され一部開口している外壁部７ｂと、これら内壁部７ａ及び外壁部７ｂの上端を接続する屋根部７ｃと、内壁部７ａ及び外壁部７ｂの下端を接続する傾斜板群部７ｄと、前記外壁部７ｂの開口と前記ガス排出口２ｂとを接続する排出ダクト７ｅとを備えている。傾斜板群部７ｄは、円周方向に沿って同一方向に傾斜している複数の傾斜板によって構成されている。これにより、上方から流動してきた排ガスは、凝縮水分離器７の下方から分離器７内部に進入し、その流れは傾斜板群部７ｄによって円周方向のうちの一方向に方向付けられると共に、水との分離が行われる。また、前記冷却管６ａ〜６ｅから噴霧された水は、屋根部７ｃを伝って、または直接下方に落下する。下方に落下した水は、冷却室本体２の底部２ｅを伝って、または直接突出部２ｆの内部空間に集められ、凝縮水排出口２ｇから排出される。   A condensate separator 7 is disposed in the lower part of the cooling chamber body 2 and on the side of the gas outlet 2b. As shown in FIG. 2, the condensate separator 7 includes a cylindrical inner wall portion 7a, an outer wall portion 7b formed in a cylindrical shape having a larger diameter than the inner wall portion 7a and partially opened, and these inner walls. The roof portion 7c that connects the upper ends of the portion 7a and the outer wall portion 7b, the inclined plate group portion 7d that connects the lower ends of the inner wall portion 7a and the outer wall portion 7b, the opening of the outer wall portion 7b, and the gas discharge port 2b are connected And a discharge duct 7e. The inclined plate group portion 7d is constituted by a plurality of inclined plates that are inclined in the same direction along the circumferential direction. Thereby, the exhaust gas flowing from above enters the inside of the separator 7 from below the condensed water separator 7, and the flow is directed in one of the circumferential directions by the inclined plate group portion 7d, Separation from water takes place. Moreover, the water sprayed from the cooling pipes 6a to 6e falls along the roof portion 7c or directly downward. The water dropped downward is collected through the bottom portion 2e of the cooling chamber main body 2 or directly in the internal space of the protruding portion 2f, and is discharged from the condensed water discharge port 2g.

次に、上記説明したガス冷却装置１の作用について説明する。   Next, the operation of the gas cooling device 1 described above will be described.

このガス冷却装置１で、廃棄物を焼却処理した際に排出される排ガスを冷却処理する場合、まず、排ガスをガス給入口２ａから冷却室Ｃに吸入する。吸入された排ガスは、傘状部材３によって、冷却室２の内周方向に分散される。   When the exhaust gas discharged when the waste is incinerated with the gas cooling device 1 is cooled, first, the exhaust gas is sucked into the cooling chamber C from the gas inlet 2a. The sucked exhaust gas is dispersed in the inner circumferential direction of the cooling chamber 2 by the umbrella-shaped member 3.

分散された排ガスは、フィン４ａ、４ｂにガイドされて冷却されながら、冷却室Ｃの内周に沿って螺旋状に流動しつつ、下方に導かれる。   The dispersed exhaust gas is guided downward by the fins 4a and 4b and is guided downward while flowing spirally along the inner periphery of the cooling chamber C.

このとき、冷却室本体２の傘状蓋部２ｃ、側周部２ｄ、底部２ｅ及び突出部２ｆ内部に流通している冷媒により、螺旋状に流動している排ガスが間接的に冷却される。また同時に、液体導入管５ａ、５ｂにより間接冷却すると共に、冷却管６ａ〜６ｅから螺旋状に流動している排ガスに対して水を噴霧して排ガスを直接的に冷却する。さらに、フィン４ａを貫通して配設されている冷却管６ｄ、６ｅから噴霧される液体によって、フィン４ａ、４ｂに溜まる排ガス中の残留物等が洗浄される。   At this time, the exhaust gas flowing in a spiral shape is indirectly cooled by the refrigerant circulating in the umbrella-shaped lid portion 2c, the side peripheral portion 2d, the bottom portion 2e, and the protruding portion 2f of the cooling chamber body 2. At the same time, the liquid introduction pipes 5a and 5b are indirectly cooled, and water is sprayed on the exhaust gas flowing spirally from the cooling pipes 6a to 6e to directly cool the exhaust gas. Furthermore, the residue etc. in the waste gas which accumulates on the fins 4a and 4b are washed by the liquid sprayed from the cooling pipes 6d and 6e disposed through the fins 4a.

このようにして冷却された排ガスは、冷却室本体２の底部２ｅによってその流動方向を下方向から上方向へと変えられ、凝縮水分離器７の下方から分離器７内部に進入する。そして、傾斜板群部７ｄによって円周方向のうちの一方向に方向付けられた排ガスは、排出ダクト７ｅから冷却室本体２外へと排出される。   The exhaust gas thus cooled is changed in flow direction from the lower side to the upper side by the bottom 2e of the cooling chamber main body 2 and enters the separator 7 from below the condensed water separator 7. The exhaust gas directed in one of the circumferential directions by the inclined plate group portion 7d is discharged out of the cooling chamber main body 2 from the discharge duct 7e.

また、冷却管６ａ〜６ｅから噴霧され、排ガスの冷却に用いられた水及び燃焼により生成した水は、凝縮水分離器７によって排ガスと分離されて下方に落下し、突出部２ｆの内部空間に集められて凝縮水排出口２ｇから排出される。   The water sprayed from the cooling pipes 6a to 6e and used for cooling the exhaust gas and the water generated by combustion are separated from the exhaust gas by the condensed water separator 7 and fall downward, and enter the internal space of the projecting portion 2f. Collected and discharged from the condensed water discharge port 2g.

なお、上記実施形態では、液体導入管５ａ、５ｂは専ら間接的に排ガス及び冷却室Ｃを冷却するために用いているが、これら液体導入管５ａ、５ｂにも冷却管６ａ〜６ｅと同様の微細孔を設け、液体を噴霧するようにしても良い。これによれば、排ガス量の多寡変動に応じて冷却能力を変更することが可能となり、便利である。   In the above embodiment, the liquid introduction pipes 5a and 5b are exclusively used for indirectly cooling the exhaust gas and the cooling chamber C. However, the liquid introduction pipes 5a and 5b are similar to the cooling pipes 6a to 6e. You may make it provide a micropore and spray a liquid. According to this, it becomes possible to change the cooling capacity according to the variation of the exhaust gas amount, which is convenient.

なお、本発明は上記実施形態に限定されるものではなく、必要に応じて種々変更することが可能である。   In addition, this invention is not limited to the said embodiment, A various change is possible as needed.
