Description

本発明は家庭から捨てられる紙屑や木屑などの一般廃棄物、生産工場や建設現場から捨
てられるゴム屑、発砲スチロールや廃プラスチックなどの産業廃棄物あるいはこれらを混合する燃焼性の廃棄物を焼却処理する場合、煤煙や臭気その他有害物質の出現を低減し、低公害で処理する焼却処理装置に関するものである。
The present invention incinerates general waste such as paper and wood scraps discarded from households, rubber scrap discarded from production factories and construction sites, industrial waste such as foamed polystyrene and waste plastics, or combustible wastes mixed with these. In this case, the present invention relates to an incineration processing apparatus that reduces the appearance of smoke, odors and other harmful substances, and processes them with low pollution.
日本は現在資源を輸入し生産活動し、紙製品、木造製品やプラスチック製品など多くの種類の製品が多量に生産されている。また不用になった製品は紙屑、木屑、ゴム屑や廃プラスチック類などの廃棄物が大量に廃出される。また廃棄された自動車や電化製品などは工業用シュレッダーで粉砕し、鉄などの金属は有効な資源として回収し再利用できるものがあるが、ゴムやプラスチックやガラスなどのシュレッダーダストはその殆どが廃棄される。経済社会が資源循環へと徐々に移行する中で、全国自治体が所有する廃棄物処理施設の高機能化や廃棄物処理企業の出現によって、リサイクル資源の産業廃棄物から再生製品に産まれ変わる商品の数も多い。しかしながら、産業廃棄物の再生処理コストが廃棄コストよりも割高な理由から、その大半が焼却炉で焼却処理されるのが現状である。 Japan is currently importing and producing resources, and many kinds of products such as paper products, wooden products and plastic products are produced in large quantities. In addition, waste products such as paper scraps, wood scraps, rubber scraps and waste plastics are discarded in large quantities. In addition, discarded automobiles and electrical appliances are crushed by industrial shredders, and metals such as iron can be recovered and reused as effective resources, but most of shredder dust such as rubber, plastic and glass is discarded. Is done. As the economy and society gradually shifts to resource recycling, there is an increase in functionality of waste treatment facilities owned by local governments and the emergence of waste treatment companies. There are many. However, the current situation is that most of the industrial waste is incinerated in an incinerator because the recycling cost of industrial waste is higher than the disposal cost.
焼却処理には、多くの種類の焼却炉が開発されまた多く使用されている。例えば実開平7−2721号公報の「水を収容する隔壁構造からなる産業廃棄物燃焼室の燃焼排ガス出口に、斜上向状のノズル孔を周壁面に多数穿設した燃焼用空気供給パイプを内設した立設二次燃焼構造の煙突を設けた消煙焼却炉」、また実登第3070256号公報の「炉体の内部にロストルその上側に多数の空気噴射孔を穿設した燃焼空気供給管を架設しかつ上方側に焼却物投入用扉また下方側に灰取出用扉を設けた燃焼炉に、排ガス昇温用バーナーを設けた排気筒さらに煙突を兼ねかつ空気噴射孔を穿設した燃焼用空供給管を内設した排ガス燃焼筒を連接した小型焼却炉」、さらに特開2004−245478号公報の「炉体内に焼却物火格子とその下方側に灰落しダンパーを架設しかつその間に燃焼用空気供給ブロアを設けた直上を主燃焼室としその上方にバーナーと水噴霧ノズルを設けて再燃焼室とす
る燃焼炉に、排ガス冷却用空気ノズルパイプを内設した排ガス冷却筒を連接した小型焼却炉」がある。さらには特開2005−226952号公報の「焼却投入物の熱分解領域と該熱分解領域で発生した分解ガスの二次燃焼領域また前記熱分解領域で発生した灰や炭化焼却投入物の溶融領域からなり、かつ熱分解領域と二次燃焼領域にはバーナーまた溶融領域には化石燃料に空気と酸素ガスを加えた酸素富化バーナーを設けた焼却炉」もある。これらいずれの焼却炉も、紙屑や段ボールなどの一般廃棄物またゴム屑や廃プラスチックなどの産業廃棄物を焼却処理する場合に排出される排ガス中の一酸化炭素や炭化水素などの未燃焼ガスを二次燃焼させる事によって完全燃焼を図り、ダイオキシン類やその他の有害物質さらには煤煙や臭気などを大幅に抑制する。
Many types of incinerators have been developed and used for incineration. For example, in Japanese Utility Model Laid-Open No. 7-2721, a combustion air supply pipe having a number of obliquely upward nozzle holes formed on the peripheral wall surface at the combustion exhaust gas outlet of an industrial waste combustion chamber having a partition wall structure containing water is provided. A smoke extinguishing incinerator with a built-in standing secondary combustion structure chimney ”, and“ No. 3070256 ”,“ Combustion air supply with many air injection holes in the furnace body above the rooster A combustion furnace with a pipe installed and an incinerator input door on the upper side and an ash extraction door on the lower side, an exhaust tube with an exhaust gas temperature raising burner, and a chimney and an air injection hole A small incinerator with an exhaust gas combustion cylinder connected with an empty supply pipe for combustion, and Japanese Patent Application Laid-Open No. 2004-245478, “An incinerator grate in the furnace body and an ash drop damper on the lower side thereof are installed between Directly above the combustion air supply blower A combustion furnace for the main combustion chamber and re-combustion chamber provided burner and water spray nozzle thereabove, there is a small incinerator "which connected the exhaust gas cooling cylinder was internally provided with exhaust cooling air nozzle pipe. Further, in Japanese Patent Application Laid-Open No. 2005-226925, “a thermal decomposition region of an incineration input, a secondary combustion region of cracked gas generated in the thermal decomposition region, and a melting region of ash and carbonized incineration input generated in the thermal decomposition region There are also incinerators comprising an oxygen-enriched burner in which air and oxygen gas are added to fossil fuel in the pyrolysis zone and secondary combustion zone, and in the melting zone. Each of these incinerators removes unburned gases such as carbon monoxide and hydrocarbons in the exhaust gas emitted when incinerating general waste such as paper waste and cardboard, and industrial waste such as rubber waste and plastic waste. Complete combustion is achieved by secondary combustion, greatly reducing dioxins and other harmful substances, as well as smoke and odors.
しかしながら、前記した実登第3070256号公報と特開2004−245478号公報で開示された焼却炉は小型であり、また実開平7−2721号公報と特開2005−226952号公報は掲載する実施例の図面から明らかな様に少容量の焼却投入物を対象にしたものであって、焼却能力以上あるいは過剰な容量の焼却物を投入した場合に、焼却物は着火する事なく燻り始め煤煙や臭気を大量に排出し、排ガスの冷却能を著しく減退し
、ダイオキシン類やその他の有害物質や煤塵を排出するなど、大気汚染を誘発する問題があった。この様な問題から、全国の学校で所有するゴミ焼却炉を使用禁止するなど、一般廃棄物の焼却処理行為が問い直されている。

However, the incinerators disclosed in the above-mentioned actual No. 3070256 and Japanese Patent Application Laid-Open No. 2004-245478 are small-sized, and the actual examples disclosed in Japanese Utility Model Laid-Open No. 7-2721 and Japanese Patent Application Laid-Open No. 2005-226952 are disclosed. As is clear from the drawing, if the incinerated product has a small capacity, and the incinerated material exceeds the incineration capacity or an excessive amount of incinerated material, the incinerated material will start to ignite without igniting soot and odor. There is a problem of inducing air pollution, such as exhausting a large amount of gas, significantly reducing the cooling capacity of exhaust gas, and discharging dioxins and other harmful substances and dust. Due to these problems, the incineration of municipal waste is being reconsidered, such as the prohibition of the use of garbage incinerators owned by schools nationwide.

A nozzle pipe 26 having a large number of nozzle holes 25 for injecting the gas in a direction intersecting with the exhaust gas flow direction is provided. That is, the exhaust gas combustion / extinguishing furnace 19 completely burns a small volume of unburned gas remaining in the flowing exhaust gas, erases black smoke from the exhaust gas, and sends out while promoting decomposition of dioxins. The drive source of the combustion air supply blower 21 may be operated independently, or may be operated in combination with the drive source of the combustion air supply blower 10 of the combustor incinerator 1 and is not particularly limited.
27は排ガス冷却塔で、排ガス燃焼消煙炉19の排ガス送出側に接続されている。図2は排ガス冷却塔27の内部構造を縦断面図で示したもので、排ガス燃焼消煙炉19から送出された排ガスの流速を弱めるため排ガスを上方側から下方側に流す水冷式排ガス流通パイプ28には、下方側に排ガス冷却用空気供給ブロア29を設けかつ側壁面に排ガス流通方向の直交位置ないし排ガス流通方向とは反対方向つまり上方側へ10度以内の斜傾角度から冷却用空気を噴射する多数のノズル孔30を穿設した排ガス冷却用空気噴射パイプ31を内設して構成されている。すなわち、水冷式ガス流通パイプ28の内径/水冷式排ガス冷却空気噴射パイプ31の外径の比率は、排ガスの流通量の流通速度や冷却空気の噴射等によって変動するため特に限定するものでないが、本発明者らの実験によれば、ノズル孔30から噴出された空気流の先端部が水冷式排ガス流通パイプ28の側面に衝突する距離でかつ排ガスの流通を著しく妨げる事なく攪乱し、排ガスの急速冷却を促す範囲として4倍程度で配置するとよい。すなわち、本発明における排ガス冷却塔27は、燃焼物焼却炉1から排ガス燃焼炉17を経て排ガス燃焼消煙炉19を通過する高温度の排ガスを200℃以下の低温度まで一気に冷却する事で、排ガス中に含まれるダイオキシン類の再合成を完全に抑制し、ダイオキシン類が大気や水質、土壌の汚染に及ぼす影響を著しく低減化され低公害化または無公害化された排ガスとなる。つまり、この様な効果は、ノズル孔から噴出される細い線状の空気を排ガスの流通方向を断ち切る様に直交位置ないし排ガスの流通方向とは反対側の上方側へ10度以内の斜傾角度で噴射する事で、高い温度の熱を保有する排ガスを一気に冷却できる作用効果の結果である。従って、細い線状の空気流を排ガスの流通方向に沿って噴射したりあるいはその反対の上方側へ10度を超える過度の斜傾角度で噴射させては、両者の交叉力が弱められ、冷却速度が緩慢になり上記の効果が損なわれる。この様に800℃以上の高い温度から200℃以下の低温度に急速冷却する事で低公害化または無公害化された排ガスは、排ガス流入側に設けられた排ガス誘引送風機32に誘引されながら、排ガス煙突33を通って大気中に放出される。 An exhaust gas cooling tower 27 is connected to the exhaust gas delivery side of the exhaust gas combustion / extinguishing furnace 19. FIG. 2 is a longitudinal sectional view showing the internal structure of the exhaust gas cooling tower 27. A water-cooled exhaust gas distribution pipe for flowing the exhaust gas from the upper side to the lower side in order to weaken the flow rate of the exhaust gas sent from the exhaust gas combustion and extinguishing furnace 19. 28, an exhaust gas cooling air supply blower 29 is provided on the lower side, and cooling air is supplied to the side wall surface at a position orthogonal to the exhaust gas circulation direction or in a direction opposite to the exhaust gas circulation direction, that is, from an oblique angle of 10 degrees upward. An exhaust gas cooling air injection pipe 31 having a large number of nozzle holes 30 for injection is provided inside. That is, the ratio of the inner diameter of the water-cooled gas distribution pipe 28 / the outer diameter of the water-cooled exhaust gas cooling air injection pipe 31 is not particularly limited because it varies depending on the distribution speed of the exhaust gas distribution amount, the injection of cooling air, etc. According to the experiments by the present inventors, the tip of the air flow ejected from the nozzle hole 30 is disturbed without significantly disturbing the flow of the exhaust gas at a distance where it collides with the side surface of the water-cooled exhaust gas distribution pipe 28, It is good to arrange about 4 times as a range which promotes rapid cooling. That is, the exhaust gas cooling tower 27 in the present invention cools the high temperature exhaust gas passing through the exhaust gas combustion furnace 17 from the combustor incinerator 1 through the exhaust gas combustion furnace 17 to a low temperature of 200 ° C. or less at a stretch. The resynthesis of dioxins contained in the exhaust gas is completely suppressed, and the influence of dioxins on air, water quality, and soil pollution is significantly reduced, resulting in a low pollution or non-polluted exhaust gas. That is, such an effect is obtained by tilting the thin linear air ejected from the nozzle hole to an orthogonal position or an upper side opposite to the exhaust gas flow direction within 10 degrees so as to cut off the exhaust gas flow direction. This is a result of the effect of being able to cool the exhaust gas that retains high temperature heat at a stroke by injecting at the same time. Therefore, if a thin linear air stream is injected along the flow direction of the exhaust gas, or is injected at an excessive oblique angle exceeding 10 degrees on the opposite upper side, the crossing force between the two is weakened and cooling is performed. The speed becomes slow and the above effect is lost. In this way, the exhaust gas that has been made less pollutant or non-polluted by rapid cooling from a high temperature of 800 ° C. or more to a low temperature of 200 ° C. or less is attracted to the exhaust gas induction blower 32 provided on the exhaust gas inflow side, It is discharged into the atmosphere through the exhaust gas chimney 33.
さらに本発明の他の一実施例として、上記の様に排ガス冷却塔27で低公害に改質された排ガス中のごく少量のNOx、SOx、HCl、HF等の有害物質を除去し、無公害化
するために排ガス浄化槽34が排ガス冷却塔27の排ガス送出側に接続される。図3は排ガス浄化槽34の一部断面図を示したもので、排ガスが流通するボックス、パイプなどの排ガス流通槽35の排ガス流通路にバグフィルター36を架設すると共に、排ガス流入側
に排ガス中に含まれるNOxなどの酸性ガスを吸着する粉末剤を収納しかつ噴出する酸性ガス吸着粉末供給装置37を付設して構成されている。なお、本発明においてバグフィルター36は排ガス中の不純物や不純ガスを除去するものであって、図3で示すように排ガス流通路に一枚または二枚以上を並列し、あるいは積み重ねて配列したり、蛇腹状に組み立てたりまたU字状に曲げ加工を施して架設するなど排ガスがバグフィルター36の通過目を通過できる構造であればよく、その配列や加工などについては特に限定するものではい。つまり、排ガス浄化槽34は酸性ガス吸着粉末供給装置37から必要に応じて消石灰などの酸性ガス粉末剤を噴出させ、バグフィルター36の排ガス流入側表面にコーティング層を形成する事によって、排ガス中に含まれるNOxなどの酸性ガスを吸着しさらには浮遊する超微細な煤塵まで排除し、無公害な排ガスのみを排ガス煙突33から大気に放出する。
Furthermore, as another embodiment of the present invention, as described above, a very small amount of harmful substances such as NOx, SOx, HCl, HF and the like in the exhaust gas modified to low pollution by the exhaust gas cooling tower 27 is removed, and no pollution is caused. Therefore, the exhaust gas purification tank 34 is connected to the exhaust gas delivery side of the exhaust gas cooling tower 27. FIG. 3 shows a partial cross-sectional view of the exhaust gas purification tank 34. A bag filter 36 is installed in the exhaust gas flow passage of the exhaust gas circulation tank 35 such as a box and a pipe through which the exhaust gas circulates. An acid gas adsorbing powder supply device 37 that houses and ejects a powder agent that adsorbs an acid gas such as NOx contained therein is provided. In the present invention, the bag filter 36 removes impurities and impure gas in the exhaust gas. As shown in FIG. 3, one or more of the bag filters 36 are arranged in parallel or stacked in the exhaust gas flow path. As long as the exhaust gas can pass through the passage of the bag filter 36, such as assembling in a bellows shape or bending in a U-shape, the arrangement and processing are not particularly limited. That is, the exhaust gas purification tank 34 ejects an acidic gas powder agent such as slaked lime as necessary from an acidic gas adsorbing powder supply device 37, and forms a coating layer on the exhaust gas inflow side surface of the bag filter 36, thereby including in the exhaust gas. It adsorbs acidic gas such as NOx and eliminates even fine dust particles that float, and releases only non-polluting exhaust gas from the exhaust chimney 33 to the atmosphere.
上記の様に構成された本発明の低公害焼却処理装置は、燃焼焼却炉1の主燃焼室4において、焼却物投入装置7の焼却物投入ドア6を開放して燃焼物焼却炉1の焼却物多段受載ロストル3に投載された紙屑、木屑、ゴム屑や廃プラスチックなど燃焼性の一般廃棄物や産業廃棄物等の投入焼却物8を、燃焼用空気供給ブロア10に連接された各段毎に設けられた二股構造の燃焼用空気噴出パイプ12のノズル孔11から空気を過給気状態で供給しながら、燃焼用バーナー9から噴射する火焔で焼却する。このとき投入焼却物8を効率的に焼却するため、燃焼用空気噴出パイプ12のノズル孔11から空気を供給し得ない投入焼却物8の投載状況にあるときは、投入焼却物払拭バー13を押し込んで障害になる投入焼却物8を移動させるとよい。また投入焼却物8の投載量に応じて焼却物多段受載ロストル3の分段毎に設けた燃焼用空気噴出パイプ12のノズル孔11の使用箇所を選択したり
、あるいは空気の噴射量を調整する事で、無駄な熱エネルギーを消費する事なく効率的に焼却する事ができる。主燃焼室4で発生した焼却灰は、焼却物多段受載ロストル3から自然落下しまたは上下に揺動可能な最下段の焼却物多段受載ロストル3を可動させて強制落下させて後焼却室5で一旦収容し、完全に焼却灰化した後、焼却灰廃出口15から炉外に廃棄する。
In the main combustion chamber 4 of the combustion incinerator 1, the low-pollution incineration processing apparatus of the present invention configured as described above opens the incineration material input door 6 of the incinerated material input device 7 and incinerates the combustion material incinerator 1. Each of the incinerated materials 8 such as paper waste, wood waste, rubber waste and waste plastic placed on the multi-stage receiving rooster 3 is connected to the combustion air supply blower 10. While supplying air in a supercharged state from the nozzle hole 11 of the combustion air jet pipe 12 having a bifurcated structure provided for each stage, incineration is performed with a flame injected from the combustion burner 9. At this time, in order to efficiently incinerate the input incinerated product 8, when the input incinerated product 8 cannot be supplied with air from the nozzle hole 11 of the combustion air jet pipe 12, the input incinerated product wiping bar 13 is placed. It is good to move the incinerated product 8 which becomes an obstacle by pushing in. Further, the use location of the nozzle hole 11 of the combustion air ejection pipe 12 provided for each stage of the incinerated multi-stage receiving roster 3 is selected according to the loaded amount of the incinerated product 8 or the amount of injected air is determined. By adjusting, it can be incinerated efficiently without consuming wasteful heat energy. The incineration ash generated in the main combustion chamber 4 falls naturally from the incinerated multistage receiving rooster 3 or moves the bottom incinerator multistage receiving rooster 3 that can swing up and down and forcibly drops it to the incinerator. 5 and then completely incinerated ash, and then discarded from the incinerator ash waste outlet 15 to the outside of the furnace.
燃焼焼却炉1の主燃焼室4で投入焼却物8を焼却した際に発生する高温度の熱を保有する排ガスは、主燃焼室4の排ガス送出口に接続された排ガス燃焼炉17の排ガス燃焼用バ
ーナー18で該排ガス中の未燃焼性ガスを再燃焼させ低公害化した後、ダイオキシン類の再合成温度に降温せしめる事なく速い速度で、後続の排ガス燃焼消煙炉19に送出する。排ガス燃焼消煙炉19は、排ガス送出側に設けた排ガス消煙用ブロア24で空気を過給気状態に送り込みながら排ガス消煙用バーナー20で、排ガス中の微少量の未燃焼ガスまで完全燃焼させまた排ガス中の黒煙までも完全に消去させた後排ガス送出側に流れる排ガスを、排ガス送出側に設けた排ガス送り返す様に攪拌しつつ、炉内をダイオキン類の分解を促進する高温度に保持しながら排ガス冷却塔27に送り込む。排ガス冷却塔27は、排ガス冷却用空気供給ブロア29から供給される冷却用の空気を、高温度の熱を保有し上方側から下方側に流れる排ガスに、排ガス冷却用空気噴射パイプ31のノズル孔30から直交位置からまた、やや10度以内の斜傾角度の上向けに噴射する事によって、ダイオキシン類の再合成を完全に抑制する200℃以下の低温度まで急速に冷却し、低公害または無公害に改質して排ガス煙突33から放出する。
Exhaust gas having high temperature heat generated when the incinerated product 8 is incinerated in the main combustion chamber 4 of the combustion incinerator 1 is exhaust gas combustion of the exhaust gas combustion furnace 17 connected to the exhaust gas outlet of the main combustion chamber 4. After the unburned gas in the exhaust gas is reburned by the burner 18 to reduce pollution, it is sent to the subsequent exhaust gas combustion / extinguishing furnace 19 at a high speed without lowering to the resynthesis temperature of dioxins. The exhaust gas combustion and extinguishing furnace 19 completely burns even a small amount of unburned gas in the exhaust gas with the exhaust gas smoke extinguishing burner 20 while sending air to the supercharged state by the exhaust gas smoke eliminating blower 24 provided on the exhaust gas sending side. In addition, after the black smoke in the exhaust gas is completely erased, the exhaust gas flowing to the exhaust gas sending side is stirred so that the exhaust gas provided on the exhaust gas sending side is sent back, and the inside of the furnace is heated to a high temperature that promotes the decomposition of dioxins. The gas is sent to the exhaust gas cooling tower 27 while being held. The exhaust gas cooling tower 27 converts the cooling air supplied from the exhaust gas cooling air supply blower 29 into exhaust gas that has high-temperature heat and flows from the upper side to the lower side, and the nozzle holes of the exhaust gas cooling air injection pipe 31. It is rapidly cooled to a low temperature of 200 ° C. or less that completely suppresses the recombination of dioxins by injecting from the orthogonal position to an oblique angle slightly within 10 degrees from 30 ° C. It is reformed into pollution and discharged from the exhaust gas chimney 33.
