Description

【0001】
【発明の属する技術分野】
本発明は、家庭の一般ごみ及び生ごみ、食堂の残飯、医療廃棄物、工からの木材、廃プラスチック等の焼却処理に適用される廃棄物焼却炉に関する。
【0002】
【従来の技術】
図3は従来の廃棄物焼却炉の構成を示す断面図である。図において、01は火格子、02は一次燃焼室、03は火格子01下部の二次燃焼室、04はバーナ、05は一次燃焼室0上部のごみ投入口、06は投入されたごみ、07は部分燃焼ガス化ガス、08は部分燃焼ガス化ガス07の循環通路、09はバーナ燃焼ガスである。10は煙突、11はバーナ04の燃料供給管、12は同じくバーナ04の一次空気供給管、13も同じくバーナ04の二次空気供給管、15は燃料で燃料供給管11へ供給される。16はブロワ、17は一次空気で一次空気供給管12を流れる。21は二次空気で二次空気供給管13を流れる。22はディフューザ、23は吸引室である。
【0003】
上記の図3に示す廃棄物焼却炉において、炉内は火格子01を介して一次燃焼室02と二次燃焼室03に分かれており、二次燃焼室03入口にバーナ04を設置している。ごみ投入口05から投入されたごみ06は、火格子01により一次燃焼室02に蓄えられる。
【0004】
このごみ06は、バーナ04の燃焼ガスの一部(約30%)を火格子01下から一次燃焼室02に供給することにより、部分燃焼し、ガス化される。この部分燃焼により生じた部分燃焼ガス化ガス07は、二次燃焼室02内を上昇し、循環通路08を通ってバーナ燃焼ガス09部に吸引混合され、二次燃焼室03で完全焼却が図られ、煙突10から大気へ放出される。このように、ごみ06をガス化し、そのガスを循環し、完全焼却することにより、無煙無臭化が計られる。
【0005】
【発明が解決しようとする課題】
前述の廃棄物焼却炉においては、火格子01上に投入されたごみ06は種々雑多であり、水分等も含んでおり、一般的に通気抵抗が高い。よって、バーナ04着火直後しばらくの間は、バーナ燃焼ガス09の大部分が煙突10側へと流れ、ごみ06への着火及びガス化開始までに時間を要することになる。そのため、ごみ06の完全焼却に時間を要し、経済性が悪くなる。
【0006】
そこで、本発明の第1の課題は、起動時間を短くし、バーナ燃焼ガスを効果的にごみの燃焼に利用でき、バーナ燃焼ガスを効果的に火格子上のごみに投入できる廃棄物焼却炉を提供することにある。
【0007】
本発明の第2の課題は、エゼクタ効果を有する焼却炉においても上記と同様に起動時間を短くできる廃棄物焼却炉を提供することにある。
【0009】
【課題を解決するための手段】
本発明は、上記の課題を解決するために、次の(1))の手段を提供する。
【0010】
(1)火格子の上部に一次燃焼室、下部に二次燃焼室を有し、同二次燃焼室にバーナを設置し、バナ燃焼ガスを前記火格子へ送り、前記一次燃焼室の投入口から前記火格子上に投入したごみを燃焼させる廃棄物焼却炉において前記二次燃焼室内の前記バーナの下部に空気を上方に向かって噴射する空気噴出ノズルを設け、前記空気噴出ノズルの噴出方向軸線は、前記バーナ燃焼ガスの噴出方向軸線と交差し、かつ前記火格子の中心に向いていることを特徴とする廃棄物焼却炉。
【0011】
(2)上記の(1)において、前記一次燃焼室と二次燃焼室とはガス循環通路で連通させ、火格子上のごみをバーナ燃焼ガスの一部を用いて部分燃焼させてガス化し、そのガスを前記バーナ燃焼ガスのエゼクタ効果により、前記ガス循環通路を通じて同バーナ燃焼ガスに循環させて前記ごみを完全燃焼させることを特徴とする廃棄物焼却炉。
【0013】
本発明の(1)の手段においては、ごみが投入口より火格子上に投入され、バーナが着火されて火炎を形成すると共に空気噴出ノズルより空気を火格子に向けて噴射する。バーナ燃焼ガスは、この下方からの空気噴出ノズルの空気噴出エネルギで火格子側へ吹き付けられ、火格子の上方へ送られる。よって火格子への熱負荷が増大し、ごみの燃焼が開始され、通気抵抗が減少すると空気噴出ノズルからの空気噴射を停止する。これにより、従来、バーナ着火直後で通気抵抗が高い間に無駄に煙突に流れていた燃焼ガスが少くなり、着火に要する時間を短くし、経済性を良くすることができる。
また、空気噴出ノズルの噴出方向軸線の向きがバーナ燃焼ガスの噴出方向軸線と交差し、かつ、火格子の中心を向いているので空気が効果的にバーナ燃焼ガスに当り、かつ火格子の熱負荷を効果的に増大させることができる。
【0014】
本発明の(2)では、バーナ燃焼ガスのエゼクタ効果により、ごみを部分燃焼させ、ガス化したガスをガス循環通路を通して循環させるので、ごみの部分燃焼及びガス化が開始され、ごみ通気抵抗が減少し、部分燃焼ガス化ガスの循環が適正量に達したならば空気噴出ノズルからの空気噴出を停止する。これにより、エゼクタ効果を有する廃棄物焼却炉においても(1)と同様の効果が得られる。
【0016】
【発明の実施の形態】
以下、本発明の実施の形態について図面に基づいて具体的に説明する。図1は本発明の実施の一形態に係る廃棄物焼却炉の構成を示す断面図、図2はバーナ部分の詳細を示す断面図である。図1において、符号01乃至09、10乃至13、15乃至17、21乃至23は図3に示す従来例と同一の機能を有するものであり、説明を省略し、そのまま引用して説明するが、本発明の特徴部分は符号24,25,26及び27の部分であり、以下に詳しく説明する。
【0017】
図1において、24はバーナ04の下部に設置した空気噴出ノズル、27は二次空気供給管13と空気噴出ノズル24間の配管、25は弁であり、配管27の途中に設けられている。26は三次空気であり、配管27から空気噴出ノズル24へ供給され、同空気噴出ノズル24先端から二次燃焼室03内へ噴出する。
【0018】
上記のように、空気噴出ノズル24がバーナ04下方の二次燃焼室03に設置され、空気噴出ノズル24はその噴出方向軸線がバーナ燃焼ガス09噴出方向軸線と交差し、かつ、火格子01の中心に向くよう配置される。又、空気噴出ノズル24はブロワ16と弁25を介して配管27で接続されており、二次空気21の一部が三次空気26として二次燃焼室03に供給することができる。
【0019】
上記に説明のバーナ04は、又エゼクタ効果を有しており、その作用を図2により説明する。図2は、図1におけるバーナ部の詳細を示した図であり、14はバーナ04の保炎板、18は予混合空気噴出口で、一次空気供給管12の先端部に設けられている。19はバーナ04の着火装置、20は火炎である。その他は図1のものと同一の構成であるので説明は省略する。
【0020】
上述のようにバーナ04は燃料供給管11、一次空気供給管12、二次空気供給管13から成り、同軸の3重管となっている。燃料供給管11の下流先端は一次空気供給管12の管内、一次空気供給管12の下流先端は二次空気供給管13の管外まで伸びており先端には保炎板14が設置されている。
【0021】
供給された燃料15は燃料供給管11を通って一次空気供給管12管内へと流れ、ブロワ16から供給された一次空気17と混合し、先端部の予混合空気噴出口18から噴出後、着火装置19により着火し、火炎20を形成する。不足分の空気は二次空気21として供給し、火炎20と拡散混合させる。
【0022】
この火炎20がディフューザ22へと入り込むことによりエゼクタ効果が発生し、この結果、吸引室23が負圧となり、循環通路08と吸引室23を通り、図中点線で示すように部分燃焼ガス化ガス07がバーナ燃焼ガス09へ供給されることになる。
【0023】
次に、上記に説明した構成の実施の形態における廃棄物焼却炉の運転手順及び作用を以下に説明する。
【0024】
(1)まず、ごみ投入口05からごみ06を投入する。
(2)ブロワ16を起動し、一次空気17、二次空気21を通気する。
【0025】
(3)着火装置19を起動し、図示されていない燃料供給設備から燃料供給管11へ燃料15を供給し、バーナ04で着火燃焼させ火炎20を形成させる。着火直後はごみ06の通気抵抗が大きくバーナ燃焼ガス09はそのほとんどが煙突10へと流れる。
【0026】
(4)バーナ04の燃焼が安定したならば、直に弁25を開け、空気噴出ノズル24から三次空気26を噴射する。三次空気26の噴射エネルギにより、バーナ燃焼ガス09の大部分は火格子01側へと方向が変えられるため、ごみ06に与える熱負荷が増大し、ごみ06の着火燃焼、ガス化開始が促進される。つまり、三次空気26を投入することにより、起動時間を短縮することができる。なお、弁25の開度を調整し、空気量を制御するようにすれば、よりきめ細かな燃焼の制御が可能となる。
【0027】
(5)ごみ06の部分燃焼・ガス化が開始し、部分燃焼ガス化ガス07の循環が安定したならば弁25を閉め、三次空気26を停止する。このような作用により、ごみ06への着火するまでの時間が短くなり、完全焼却に要する時間が短く、経済的な焼却炉となる。
【0028】
【発明の効果】
以上、具体的に説明したように、本発明は、火格子の上部に一次燃焼室、下部に二次燃焼室を有し、二次燃焼室内にバーナを設置し、火格子上のごみを燃焼させる廃棄物焼却炉において、前記二次燃焼室内のバーナ下部に空気噴出ノズルを設け、この空気噴出ノズルの噴出方向軸線をバーナ燃焼ガスの噴出方向軸線と交差し、かつ火格子の中心に向けた構成を基本とし、この構成に加え、一次燃焼室と二次燃焼室とを連通するガス循環通路を設け、エゼクタ効果により部分燃焼させてガス化したガスを循環させる構成も提供するので、起動時間が短く経済的で、かつ、無煙無臭のごみ焼却炉を提供することができる。
【0029】
更に、エゼクタ効果を有する廃棄物焼却炉においても空気噴出ノズルを設けることにより、上記と同様の効果を得ることができる。

Garbage 06 thrown in from the garbage inlet 05 is stored in the primary combustion chamber 02 by the grate 01.
[0004]
The waste 06 is partially combusted and gasified by supplying a part (about 30%) of the combustion gas of the burner 04 to the primary combustion chamber 02 from below the grate 01. The partially combusted gasified gas 07 generated by the partial combustion ascends in the secondary combustion chamber 02, is sucked and mixed into the burner combustion gas 09 through the circulation passage 08, and is completely incinerated in the secondary combustion chamber 03. And discharged from the chimney 10 to the atmosphere. In this way, smoke 06 is measured by gasifying the waste 06, circulating the gas, and completely incinerating it.
[0005]
[Problems to be solved by the invention]
In the above-mentioned waste incinerator, the garbage 06 put on the grate 01 is miscellaneous, contains moisture and the like, and generally has high ventilation resistance. Therefore, for a while immediately after the burner 04 is ignited, most of the burner combustion gas 09 flows to the chimney 10 side, and it takes time to ignite the garbage 06 and start gasification. For this reason, it takes time to completely incinerate the waste 06, resulting in poor economic efficiency.
[0006]

[0007]
The second object of the present invention is to provide a waste incinerator capable of shortening the start-up time in the incinerator having the ejector effect as described above.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides the following means (1) and ( 2 ).
[0010]
(1) the primary combustion chamber at the top of the grate has a secondary combustion chamber in the lower part, a burner installed in the secondary combustion chamber, feeding the bar burner combustion gas into the grate, the primary combustion chamber of the waste incinerator for burning waste was loaded onto the grate from the inlet, provided an air ejection nozzle for ejecting toward the air above the lower portion of the burner of the secondary combustion chamber, said air injection nozzle The waste incinerator is characterized in that an ejection direction axis of the gas intersects with the burner combustion gas ejection direction axis and faces the center of the grate .
[0011]
(2) In the above (1), the primary combustion chamber and the secondary combustion chamber communicate with each other through a gas circulation passage, and the dust on the grate is partially burned using a part of the burner combustion gas to be gasified, A waste incinerator characterized in that the waste is completely burned by circulating the gas to the burner combustion gas through the gas circulation passage by the ejector effect of the burner combustion gas.
[0013]
In the means of (1) of the present invention, dust is thrown into the grate from the inlet, the burner is ignited to form a flame, and air is jetted from the air ejection nozzle toward the grate. The burner combustion gas is blown to the grate side by the air jet energy of the air jet nozzle from below, and is sent to the upper side of the grate. Therefore, when the thermal load on the grate increases, the combustion of dust starts, and when the ventilation resistance decreases, the air injection from the air ejection nozzle is stopped. As a result, the combustion gas that has conventionally flowed unnecessarily to the chimney immediately after burner ignition while the ventilation resistance is high is reduced, and the time required for ignition can be shortened and the economy can be improved.
Also, the direction of the jet direction axis of the air jet nozzle intersects the burner combustion gas jet direction axis and faces the center of the grate, so that the air effectively hits the burner combustion gas and the heat of the grate The load can be increased effectively.
[0014]
In (2) of the present invention, due to the ejector effect of the burner combustion gas, the waste is partially combusted and the gasified gas is circulated through the gas circulation passage, so that the partial combustion and gasification of the waste is started, and the dust ventilation resistance is reduced. When the amount of gas is reduced and the circulation of the partial combustion gasification gas reaches an appropriate amount, the air ejection from the air ejection nozzle is stopped. Thereby, also in the waste incinerator which has an ejector effect, the effect similar to (1) is acquired.
[0016]
