Description

本発明は、例えば家庭ゴミ等の一般廃棄物や、産業廃棄物等の焼却処理に用いられる焼却炉に関するものである。   The present invention relates to an incinerator used for incineration of, for example, general waste such as household waste and industrial waste.
従来、焼却炉として、炉体に設けられた開閉可能な投入口から焼却物を投入して燃焼室内でバーナーにより焼却物を燃焼させ、燃焼により生じる煤煙を煙突体から排出する構造のものが一般的であるが、このような一次的な燃焼方式では、炉体内での焼却物の燃焼が不完全燃焼となり易く、ダイオキシンなどの有害物質や粉塵、COを含む煤煙などを大量に大気中に放出し、環境汚染の大きな原因となっている。   Conventionally, as an incinerator, an incinerator is generally introduced from an openable / closable inlet provided in the furnace body, the incinerator is burned by a burner in a combustion chamber, and the smoke generated by the combustion is discharged from the chimney. However, with such a primary combustion method, combustion of incinerated materials in the furnace tends to be incomplete combustion, releasing a large amount of harmful substances such as dioxin, dust, and CO-containing smoke. It is a major cause of environmental pollution.
そこで、焼却物を燃焼させるための一次燃焼室に加え、この一次燃焼室からの燃焼ガスを更に燃焼させるための二次燃焼室を一次燃焼室の上方で炉体内部に形成し、再燃バーナーにより再燃焼させるようにして、COなどの未燃焼ガスうや煤煙の燃焼を促進するようにしたものが、例えば特許文献1や特許文献2で提案されている。   Therefore, in addition to the primary combustion chamber for burning the incinerated products, a secondary combustion chamber for further combustion of the combustion gas from the primary combustion chamber is formed inside the furnace body above the primary combustion chamber, and a reburn burner is used. For example, Patent Document 1 and Patent Document 2 have proposed that the combustion of unburned gas such as CO and soot is promoted by reburning.
しかし、この特許文献1や特許文献2の燃焼炉は、二次燃焼室を設けたことによりある程度の燃焼効果を高めることができるが、二次燃焼室が一次燃焼室の上段に隔壁によって区分けされた状態で個別に設けられているため、焼却炉全体が大型化すると共に、二次燃焼室の熱が一次燃焼室内の焼却物の加熱に利用されることがないので、熱損失が大きく燃料費等の運転コストが高くつき不経済であるといった問題点があった。   However, although the combustion furnaces of Patent Document 1 and Patent Document 2 can improve the combustion effect to some extent by providing the secondary combustion chamber, the secondary combustion chamber is divided into upper walls of the primary combustion chamber by a partition wall. Since the entire incinerator is enlarged and the heat in the secondary combustion chamber is not used for heating the incinerated material in the primary combustion chamber, the heat loss is large and the fuel cost is high. There is a problem that the operation cost is high and uneconomical.
また、炉体内に水平な助燃筒を設けて、助燃筒の上方にある投入口から焼却物を投入し、助燃筒の一端側からバーナーの火炎を噴射させて焼却物を燃焼させ、その排ガスを垂直な二次燃焼筒に導いて再燃焼させる焼却炉が特許文献3で提案されている。   In addition, a horizontal auxiliary combustion cylinder is provided in the furnace body, incineration material is introduced from the inlet above the auxiliary combustion cylinder, a burner flame is injected from one end of the auxiliary combustion cylinder to burn the incineration material, and the exhaust gas is discharged. Patent Document 3 proposes an incinerator that leads to a vertical secondary combustion cylinder and reburns it.
この特許文献3の焼却炉も、先に述べた焼却炉と同じように、二次燃焼筒が一次燃焼させるための助燃筒とは区分けされた状態で個別に設けられているため、装置全体が大型化すると共に、二次燃焼筒の熱が助燃筒での焼却物の加熱に利用されることがないので、熱損失が大きく、且つ燃料費が高くついて不経済であるといった欠点があった。
特開平9−159128号公報 特開平5−231624号公報 特開2005−291687号公報
Similarly to the incinerator described above, the incinerator of Patent Document 3 is also provided separately in a state in which the secondary combustion cylinder is separated from the auxiliary combustion cylinder for primary combustion. In addition to the increase in size, the heat of the secondary combustion cylinder is not utilized for heating the incinerated product in the auxiliary combustion cylinder, so that there are disadvantages that the heat loss is large and the fuel cost is high, which is uneconomical.
JP-A-9-159128 JP-A-5-231624 JP 2005-291687 A
そこで本発明は上記の課題を解決することを図るものであって、コンパクトで燃焼効率がよく、排出ガスが無煙、無臭でしかもダイオキシン等の有害物質や、粉塵、COなどの発生を著しく減少させることのできる焼却炉を低コストで提供することを主たる目的とするものである。   Accordingly, the present invention is to solve the above-mentioned problems, and is compact and has good combustion efficiency, and the emission gas is smokeless and odorless, and the generation of harmful substances such as dioxin, dust, and CO is remarkably reduced. The main purpose is to provide an incinerator that can be used at low cost.
上記目的を達成するために本発明では次のような技術的手段を講じた。即ち、本発明に係る焼却炉にあっては、焼却物を乾溜ガス化するための乾溜ガス室を内部に備えた炉体と、乾溜ガス室内の焼却物を焼却して乾溜ガス化する第1の燃焼器と、乾溜ガス室で発生した乾溜ガスを二次燃焼させるための燃焼筒と、燃焼筒内に乾溜ガスを流入するために燃焼筒周壁に形成された乾溜ガス流入孔と、燃焼筒内の乾溜ガスを燃焼させるための第2の燃焼器と、燃焼筒内の排ガスを外部に排出するための煙突とからなり、前記燃焼筒の少なくとも前記乾溜ガス流入孔を含む一部が乾溜ガス室の領域内に配置されており、前記燃焼筒が乾溜ガス室を上下に貫通して配置されていてその上端に第2の燃焼器が設けられ、燃焼筒下部で前記煙突に連通され、乾溜ガス室の上部で燃焼筒周壁に乾溜ガスを流入させるための乾溜ガス流入孔が設けられている構造とした。
In order to achieve the above object, the present invention takes the following technical means. That is, in the incinerator according to the present invention, a furnace body provided with a dry distillation gas chamber for converting the incinerated product into a dry distillation gas, and a first in which the incinerated product in the dry distillation gas chamber is incinerated and converted into a dry distillation gas. A combustor, a combustion cylinder for secondary combustion of the dry distillation gas generated in the dry distillation gas chamber, a dry distillation gas inflow hole formed in a peripheral wall of the combustion cylinder for flowing the dry distillation gas into the combustion cylinder, and a combustion cylinder And a chimney for discharging the exhaust gas in the combustion cylinder to the outside, and a part of the combustion cylinder including at least the dry distillation gas inflow hole is dry distillation gas. Disposed in the region of the chamber, the combustion cylinder is disposed vertically through the dry gas chamber, and a second combustor is provided at the upper end thereof, communicated with the chimney at the lower portion of the combustion cylinder, Distilled gas for allowing the distilled gas to flow into the peripheral wall of the combustion cylinder at the top of the gas chamber And a structure in hole is provided.
本発明の焼却炉は上記の如く構成したので、第1の燃焼器の燃焼によって生じた乾溜ガス室の乾溜ガスが燃焼筒内に流入して第2の燃焼器により再燃されると共に、燃焼筒の乾溜ガス流入孔を含む一部が乾溜ガス室の領域を貫通して配置されている構造としたので、乾溜ガス室内にある燃焼筒の筒壁からの放射熱を乾溜ガスの加熱に利用することができて燃焼効率を更に高めることができ、これにより無煙、無臭でしかもダイオキシン等の有害物質や、粉塵、COなどの発生を著しく減少させるとともに燃費の削減を図ることができる、といった効果がある。更に加えて本発明では、前記燃焼筒が、乾溜ガス室を上下に貫通して配置されていてその上端に第2の燃焼器が設けられ、燃焼筒下部で前記煙突に連通され、乾溜ガス室の上部で燃焼筒周壁に乾溜ガスを流入させるための前記乾溜ガス流入孔が設けられている構造としたので、乾溜ガス室上部で燃焼筒に流入して再燃された排ガスは燃焼筒に沿って下方に流れるので、乾溜ガス燃焼後の高温の排ガスの熱を、乾溜ガス室内で燃焼筒上部から下部にわたって広い範囲で筒壁からの放射熱として有効に利用できると共に、燃焼筒を炉体から上部や側方に大きくはみ出ない状態でコンパクトに組成することができる、といった効果がある。

以下において本発明にかかる焼却炉の具体的な内容を図に示した実施例に基づき説明する。図1〜図3は本発明の焼却炉の第1の実施例を示すものであって、符号1で炉本体を示す。炉本体1の内部に乾溜ガス室2が設けられ、焼却物を乾溜ガス室2に投入するための投入口3が炉本体1の壁面に設けられている。また、乾溜ガス室2に投入された焼却物Cを燃焼させるためのバーナー等の第1の燃焼器4が乾溜ガス室2の下方に配置されている。   The specific contents of the incinerator according to the present invention will be described below based on the embodiments shown in the drawings. 1 to 3 show a first embodiment of an incinerator according to the present invention. A dry distillation gas chamber 2 is provided inside the furnace main body 1, and an inlet 3 for introducing incinerated products into the dry distillation gas chamber 2 is provided on the wall surface of the furnace main body 1. In addition, a first combustor 4 such as a burner for burning the incinerated substance C put into the dry distillation gas chamber 2 is disposed below the dry distillation gas chamber 2.
更に、乾溜ガス室2で焼却物Cを燃焼させることにより発生した乾溜ガスを再燃焼させるための燃焼筒7が設けられている。この燃焼筒7は、乾溜ガス室2内で乾溜ガスを燃焼筒内に流入させる複数の乾溜ガス流入孔6を備えた上下に長い筒部材7によって形成されている。本実施例では、乾溜ガス室2の上方部分が庇のように炉体側方に張り出して形成され、この張り出した乾溜ガス室2を上下に貫通するように燃焼筒7が配置されている。また、乾溜ガス流入孔6から燃焼筒7内に流入した乾溜ガスを燃焼させるためのバーナー等の第2の燃焼器8が燃焼筒7の上端に設けられ、燃焼筒7の下部は乾溜ガスを燃焼することによって生じた排ガスを外部に排出するための煙突12が接続されている。   Further, a combustion cylinder 7 is provided for recombusting the dry distillation gas generated by burning the incinerated substance C in the dry distillation gas chamber 2. The combustion cylinder 7 is formed by a vertically long cylinder member 7 provided with a plurality of dry distillation gas inflow holes 6 through which dry distillation gas flows into the combustion cylinder in the dry distillation gas chamber 2. In the present embodiment, the upper portion of the dry distillation gas chamber 2 is formed so as to project to the side of the furnace body like a soot, and the combustion cylinder 7 is arranged so as to penetrate the protruding dry distillation gas chamber 2 up and down. In addition, a second combustor 8 such as a burner for combusting the dry distillation gas flowing into the combustion cylinder 7 from the dry distillation gas inflow hole 6 is provided at the upper end of the combustion cylinder 7, and the lower part of the combustion cylinder 7 stores the dry distillation gas. A chimney 12 for discharging exhaust gas generated by combustion to the outside is connected.
上記第1の燃焼器4並びに第2の燃焼器8は、燃料噴射ノズル9と、該噴射ノズル9の燃料噴射軸線に対して接線方向に空気を供給する空気旋回供給器10、燃焼用空気取入れ口11並びに点火装置(図示外)とからなり、空気旋回供給器10は図3に示すように、断面リング状の形態をなし、外周面から内側空間に向かって接線方向に開口した複数の空気導入孔10aを備え、ここから導入した空気と燃料噴射ノズル9からの燃料とによる火炎に渦流を発生させるように形成されている。   The first combustor 4 and the second combustor 8 include a fuel injection nozzle 9, an air swirl supply device 10 that supplies air in a tangential direction with respect to the fuel injection axis of the injection nozzle 9, and combustion air intake As shown in FIG. 3, the air swirler 10 includes a mouth 11 and an ignition device (not shown). The air swirler 10 has a ring shape in cross section, and is opened in a tangential direction from the outer peripheral surface toward the inner space. An introduction hole 10a is provided, and is formed so as to generate a vortex in a flame caused by air introduced from the introduction hole 10a and fuel from the fuel injection nozzle 9.
上記の構成において、乾溜ガス室2に焼却物Cを投入して第1の燃焼器4を作動させて焼却物を燃焼させることにより乾溜ガス室2内に乾溜ガスが発生する。この乾溜ガスは、乾溜ガス流入孔6から燃焼筒7内に流入して第2の燃焼器8の火炎により再燃されてほぼ完全に燃焼され、その排ガスは煙突12から外部に排出される。また、乾溜ガス室2内で、燃焼筒7の筒壁から放射熱が乾溜ガス室2に放射されて焼却物Cを加熱して燃焼効率を更に助長する。これにより、煙突12から排出される排ガスが無煙、無臭で、しかもダイオキシン等の有害物質や、粉塵、COなどの含有量を著しく減少させることができると共に、燃費の節減を図ることができる。尚、前記燃焼筒7は、少なくとも乾溜ガス室2内に位置する部分を鉄等の熱伝導性に優れた材料で形成するのが好ましい。これにより燃焼筒7の筒壁からの放射熱の熱量を高めることができる。   In the above-described configuration, the incinerated gas C is generated in the dry distillation gas chamber 2 by putting the incinerated material C into the dry distillation gas chamber 2 and operating the first combustor 4 to burn the incinerated material. The dry distillation gas flows into the combustion cylinder 7 from the dry distillation gas inflow hole 6, is reburned by the flame of the second combustor 8 and is almost completely burned, and the exhaust gas is discharged from the chimney 12 to the outside. In the dry distillation gas chamber 2, radiant heat is radiated from the cylindrical wall of the combustion cylinder 7 to the dry distillation gas chamber 2 to heat the incinerated substance C and further promote combustion efficiency. As a result, the exhaust gas discharged from the chimney 12 is smokeless and odorless, and the contents of harmful substances such as dioxin, dust, and CO can be significantly reduced, and fuel consumption can be reduced. In addition, it is preferable that the combustion cylinder 7 is formed of at least a portion located in the dry distillation gas chamber 2 with a material having excellent thermal conductivity such as iron. Thereby, the calorie | heat amount of the radiant heat from the cylinder wall of the combustion cylinder 7 can be raised.
また、上記燃焼器4,8において、噴射ノズル9の燃料噴射軸線に対して空気旋回供給器10の空気導入孔10aから接線方向に空気が供給されるので、点火された火炎に渦流が発生して空気と燃料とが効率よく混合攪拌され、効率よく燃焼させることができる。   Further, in the combustors 4 and 8, air is supplied in a tangential direction from the air introduction hole 10 a of the air swirl feeder 10 with respect to the fuel injection axis of the injection nozzle 9, so that a vortex flow is generated in the ignited flame. Thus, air and fuel are mixed and stirred efficiently, and can be burned efficiently.
図4は、前記燃焼筒7の乾溜ガス室2内に配置される部分を冷却する冷却手段13を設けた実施例を示すものであって、この実施例では冷却手段13が外気による空冷で行うように形成されている。即ち、乾溜ガス室2内で燃焼筒7の周壁の一部が間隙14を持った2重壁構造とされ、この間隙14の上端が第2の燃焼器8の空気旋回供給器10に連通され、下端が空気取入れ口15に連通されている。これにより、乾溜ガス室2内の高温による燃焼筒7の熱損傷を防止することができるとともに、熱交換で加温された空気によって第2の燃焼器8の燃焼を促進することができるようになっている。   FIG. 4 shows an embodiment provided with a cooling means 13 for cooling a portion of the combustion cylinder 7 arranged in the dry distillation gas chamber 2. In this embodiment, the cooling means 13 is air-cooled by outside air. It is formed as follows. That is, a part of the peripheral wall of the combustion cylinder 7 has a double wall structure with a gap 14 in the dry distillation gas chamber 2, and the upper end of the gap 14 is communicated with the air swirl feeder 10 of the second combustor 8. The lower end communicates with the air intake 15. Thereby, while being able to prevent the thermal damage of the combustion cylinder 7 by the high temperature in the dry distillation gas chamber 2, the combustion of the 2nd combustor 8 can be accelerated | stimulated with the air heated by heat exchange. It has become.
図5は、上記冷却手段13を水冷方式とした場合の実施例を示すものであって、2重壁構造となった燃焼筒7の間隙14の下端が冷却水取入れ口16に連通され、間隙14の上端が冷却水取出口17に連通されている。従ってこの実施例では、熱交換によって加温されて冷却水取出口17から取り出された温水を風呂等に有効利用することができる。   FIG. 5 shows an embodiment in which the cooling means 13 is a water cooling system. The lower end of the gap 14 of the combustion cylinder 7 having a double wall structure is communicated with the cooling water intake 16, and the gap The upper end of 14 communicates with the cooling water outlet 17. Therefore, in this embodiment, the hot water heated by heat exchange and taken out from the cooling water outlet 17 can be effectively used for a bath or the like.
また本発明では、図6に示すように、燃焼筒4の殆どの部分を乾溜ガス室2内に配置するように構成することも可能である。このようにすれば、乾溜ガス室2内での燃焼筒7からの熱放射面積が増えて大きな放射熱を得ることができ、これにより第1の燃焼器4の燃焼を低くおさえることができ、或いは一時休止させることも可能となって、消費燃料を更に節減することができる。   In the present invention, as shown in FIG. 6, it is possible to arrange so that most of the combustion cylinder 4 is disposed in the dry distillation gas chamber 2. In this way, the area of heat radiation from the combustion cylinder 7 in the dry distillation gas chamber 2 can be increased to obtain a large amount of radiant heat, whereby the combustion of the first combustor 4 can be kept low, Alternatively, it is possible to temporarily stop the fuel consumption, thereby further reducing fuel consumption.
本発明では上記した実施例に特定されるものではく、本発明の構成要件を備え、且つ上記した効果を有する範囲内で適宜変更して実施することができることは勿論である。   The present invention is not limited to the above-described embodiments, and it is needless to say that the present invention can be appropriately modified and implemented within the scope having the constituent features of the present invention and having the above-described effects.
本発明の焼却炉は家庭用に限らず、事業所や工場内での簡易焼却炉としても広範囲に利用することが可能である。   The incinerator of the present invention is not limited to home use, and can be used in a wide range as a simple incinerator in a business office or factory.
