【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、合成樹脂やゴム等を含む産業・都市廃棄物を
焼却する焼却炉において、この焼却に際して発生する燃
焼ガスに含有する塩化水素や硫黄酸化物等の有害ガスを
除去するための燃焼ガス処理方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is an incinerator that incinerates industrial and municipal waste containing synthetic resins, rubber, etc. The present invention relates to a combustion gas treatment method for removing harmful gases such as sulfur oxides.
合成樹脂やゴム等を含む産業・都市廃棄物を焼却すると
、合成樹脂やゴムの熱分解によって塩化水素や硫黄酸化
物等の有害ガスが発生するから、この有害ガスを含む燃
焼ガスから熱の回収を行う場合には、熱回収装置が腐食
し、また、そのまま大気に排出すれば大気を汚染するこ
とになる。When industrial/municipal waste containing synthetic resins and rubber is incinerated, harmful gases such as hydrogen chloride and sulfur oxides are generated due to the thermal decomposition of the synthetic resins and rubber, so it is necessary to recover heat from the combustion gas containing these harmful gases. If this is done, the heat recovery equipment will corrode, and if the heat is discharged directly into the atmosphere, it will pollute the atmosphere.
そこで先行技術としての特開昭５４−４１５６５号公報
は、焼却炉内に、炭酸カルシウム、消石灰又は生石灰等
のアルカリ剤を粉末の状態で噴霧して、燃焼ガス中の塩
化水素や硫黄酸化物と反応させることにより、アルカリ
塩の固形成分にし、焼却炉の外における集塵装置におい
て燃焼ガス中より分離除去することを提案している。Therefore, Japanese Patent Application Laid-open No. 54-41565 as a prior art proposes spraying powdered alkaline agents such as calcium carbonate, slaked lime, or quicklime into the incinerator to eliminate hydrogen chloride and sulfur oxides in the combustion gas. It is proposed that the alkali salt be converted into a solid component by reaction, and then separated and removed from the combustion gas in a dust collector outside the incinerator.
しかし、この先行技術のものは、ストーカ式焼却炉のよ
うな直接燃焼式の焼却炉において、当該焼却炉内に粉末
状のアリカル剤を噴霧するものであるから、燃焼ガス中
の有害ガスと反応したアルカリ塩は、その−部が、ロス
ドル上の焼却物の表面に落下することになる。However, since this prior art sprays a powdered alkali agent into the incinerator in a direct combustion type incinerator such as a stoker type incinerator, it reacts with harmful gases in the combustion gas. A portion of the alkali salt will fall onto the surface of the incinerated material on the Rosdol.
このように焼却物の表面に落下したアルカリ塩は、高温
の焼却物や灰と接触することによって熱分解して再び塩
化水素や硫黄酸化物等の有害ガスが発生することになる
から、除去効率が低いのであり、しかも、焼却物の表面
に落下したアルカリ塩は、焼却物の燃焼を妨げるのであ
る。The alkali salts that have fallen onto the surface of the incinerated material will thermally decompose when it comes into contact with the high-temperature incinerated material and ash, generating harmful gases such as hydrogen chloride and sulfur oxides, so the removal efficiency is low. Furthermore, the alkali salts that fall on the surface of the incinerated material hinder the combustion of the incinerated material.
その上、焼却物の燃焼は、先づ焼却物が熱分解して揮発
分が発生する際、炭素数の多いタール分が多量に発生す
るものであるから、直接燃焼式の焼却炉内に粉末状のア
ルカリ剤を噴霧することは、当該アルカリ剤の表面に前
記タール分が付着して有害ガスとの接触が阻害されるの
で、除去率が低下することになる。Furthermore, when the incinerated material is first thermally decomposed and volatile matter is generated, a large amount of tar with a large number of carbon atoms is generated. When an alkali agent is sprayed, the tar adheres to the surface of the alkaline agent and prevents contact with harmful gases, resulting in a reduction in the removal rate.
すなわち、ストーカ式焼却炉のような直接燃焼式の焼却
炉内に粉末状のアルカリ剤を噴霧する方法は、アルカリ
剤の有効な反応が得られず有害ガスの除去率が低くて、
アルカリ剤の噴霧量を多（しなければならないから、運
転経費が嵩むばかりでなく、以後の集塵装置における負
荷が増大して、集塵装置が大型化する点に問題があった
。In other words, the method of spraying a powdered alkaline agent into a direct combustion type incinerator such as a stoker type incinerator does not allow an effective reaction of the alkaline agent and has a low removal rate of harmful gases.
Since a large amount of alkaline agent must be sprayed, not only does the operating cost increase, but the load on the subsequent dust collector increases, resulting in an increase in the size of the dust collector.
本発明は、小量のアルカリ剤の噴霧によって有害ガスを
効率的に除去できる方法を提供するものである。The present invention provides a method for efficiently removing harmful gases by spraying a small amount of alkaline agent.
このため本発明は、焼却炉を乾溜炉と二次燃焼炉とに分
離し、焼却物を先づ前記乾溜炉内において不完全燃焼さ
せ、発生した可燃性ガスを前記二次燃焼炉内に導入して
完全燃焼を行うようにする一方、前記二次燃焼炉内に、
炭酸カルシウム等のアルカリ剤を、当該二次燃焼炉に対
する完全燃焼用の二次空気に混合した状態で噴霧するよ
うに構成したものである。For this reason, the present invention separates the incinerator into a dry distillation furnace and a secondary combustion furnace, first incompletely combusts the incinerated material in the dry distillation furnace, and introduces the generated flammable gas into the secondary combustion furnace. to achieve complete combustion, while in the secondary combustion furnace,
It is configured to spray an alkaline agent such as calcium carbonate mixed with secondary air for complete combustion in the secondary combustion furnace.
このように焼却炉を乾溜炉と二次燃焼炉とに分離し、焼
却物を先づ前記乾溜炉内において不完全燃焼させ、発生

燃焼炉内に供給される二次空気にて完全燃焼させる場合
、二次燃焼炉内の温度は、前記従来の直接燃焼式の焼却
炉内の温度よりも低いから、この二次燃焼炉内に炭酸カ
ルシウム等のアルカリ剤を噴霧することにより、当該ア
ルカリ剤と燃焼ガス中の有害ガスとの反応に適した温度
に維持できると共に、−旦生成したアルカリ塩が熱分解
することを回避できる。In this way, the incinerator is separated into a dry distillation furnace and a secondary combustion furnace, and the incinerated material is first incompletely combusted in the dry distillation furnace, and the generated flammable gas is introduced into the secondary combustion furnace. When complete combustion is performed using the secondary air supplied to the secondary combustion furnace, the temperature inside the secondary combustion furnace is lower than the temperature inside the conventional direct combustion type incinerator, so this secondary combustion furnace By spraying an alkaline agent such as calcium carbonate into the combustion chamber, it is possible to maintain the temperature suitable for the reaction between the alkaline agent and harmful gases in the combustion gas, and to avoid thermal decomposition of the alkali salts that have been generated. .
−方、二次燃焼炉内においては、可燃性ガスと二次空気
との急激な燃焼反応により激しい乱流状態になっている
から、前記アルカリ剤を、二次燃焼炉に対する完全燃焼
用の空気に混合して噴霧したことにより、可燃性ガス中
のタール分がアルカリ剤の表面に付着することを低減で
きると共に、可燃性ガスとアルカリ剤との接触時間、延
いては可燃性ガス中の有害ガスとアルカリ剤との接触時
間を長くすることができる。- On the other hand, in the secondary combustion furnace, there is a severe turbulent flow due to the rapid combustion reaction between the flammable gas and the secondary air. By mixing and spraying the combustible gas, it is possible to reduce the tar content in the flammable gas from adhering to the surface of the alkaline agent, and also to reduce the contact time between the flammable gas and the alkaline agent, thereby reducing the amount of harmful substances in the combustible gas. The contact time between the gas and the alkaline agent can be increased.
従って、本発明によると、アルカリ剤の噴霧による有害
ガスの除去率を、焼却物の燃焼を阻害することなく向上
できて、アルカリ剤の使用量を低減することができるか
ら、運転経費を節減できると共に、以降における集塵装
置の負荷を軽減でき集塵装置の小型化を達成できる効果
を有する。Therefore, according to the present invention, the rate of removal of harmful gases by spraying an alkaline agent can be improved without inhibiting the combustion of the incinerated material, and the amount of alkaline agent used can be reduced, so operating costs can be reduced. At the same time, it has the effect of reducing the load on the dust collector later on and making the dust collector smaller.
