Description

この発明は、主として産業廃棄物の処理について、また、一般廃棄物の処理についても適用できる廃棄物処理発電炉であって、合理的に焼却処理するとともに、その燃焼熱を発電に利用することのほかに、焼却灰類を商品化することに適した廃棄物処理発電炉に関する。   The present invention is a waste treatment power generation furnace which can be applied mainly to the treatment of industrial waste and also to the treatment of general waste, which is rationally incinerated and uses its combustion heat for power generation. In addition, the present invention relates to a waste treatment power generation furnace suitable for commercializing incinerated ash.

廃棄物を処理する焼却炉については種々の形態があるが、その一例として、炉上端の投入口から火格子が段々となる傾斜乾燥室を設け、その下において乾燥室から下りる廃棄物の燃焼室を設けたものが挙げられる。これによると、燃焼室の端の壁に重油バーナーが乾燥室に向かって炎を噴出し得るように設けられているので、上端の投入口から炉内に入れられた廃棄物は、傾斜乾燥室を下りながら燃焼熱とバーナー熱を受けることによって、水分が蒸発し乾燥するので、下端の燃焼室において燃焼が効率的に促進される。   There are various types of incinerators that process waste. As an example, an inclined drying chamber with a grate stepped from the inlet at the top of the furnace is provided, and a combustion chamber for waste that descends from the drying chamber underneath. Are provided. According to this, since the heavy oil burner is provided on the wall at the end of the combustion chamber so that the flame can be ejected toward the drying chamber, the waste put into the furnace from the top inlet is the inclined drying chamber. By receiving the combustion heat and the burner heat while descending, moisture evaporates and dries, so that combustion is efficiently promoted in the combustion chamber at the lower end.

また、別の例としては、炉を一次燃焼室と二次燃焼室とに分けたものが挙げられる。これによれば、一次燃焼室で廃棄物を燃焼させるが、その際に発生した不完全燃焼ガスを二次燃焼室に送るとともに、バーナーの炎と空気をそこに吹き込むことによりガスが完全燃焼される。   Another example is a furnace divided into a primary combustion chamber and a secondary combustion chamber. According to this, the waste is burned in the primary combustion chamber, and the incomplete combustion gas generated at that time is sent to the secondary combustion chamber, and the gas is completely burned by blowing the burner flame and air there. The

上記のような従来の焼却炉は、生ゴミや廃プラスチック類、紙くず、木屑、繊維くず、ゴムくず等の燃えるゴミの焼却には、燃焼に高熱をかける必要がなく、固形の残さも発生が少ないこと等から適し、燃焼熱を発電に利用することも容易である。しかし、殊に産業廃棄物であると、燃えるゴミの他に、金属くず、ガラスくず、コンクリートくず、陶磁器くず、がれき類、燃え殻等の燃えない固形物が含まれており、発電の燃焼熱を十分に得るには適しない。また、汚泥、廃油、動植物性残さのように処理に困るものや、高温処理を施す必要のある感染性廃棄物、アスベスト等の危険物も含まれていることがある。   Conventional incinerators such as those described above do not require the application of high heat to incinerate burning garbage, waste plastics, paper scraps, wood scraps, fiber scraps, rubber scraps, etc., and solid residues are also generated. It is suitable because it is small, and it is easy to use combustion heat for power generation. However, industrial waste, in particular, contains non-burning solids such as metal scraps, glass scraps, concrete scraps, ceramic scraps, debris, and husks in addition to burning garbage. Not good enough to get. In addition, there are cases where things that are difficult to treat, such as sludge, waste oil, and animal and vegetable residues, infectious wastes that require high-temperature treatment, and dangerous materials such as asbestos.

いずれにしても雑多な廃棄物では、ダイオキシンの発生を防止し、菌類やウイルス類を死滅させる等のために、少なくとも８００°Ｃ以上の高熱処理を要するが、従来、これらの解決には適しなく、解決するには重油バーナーの燃費が多大にかかり、しかも、地球温暖化の原因となる化石燃料の消費となる。さらに、廃棄ガスは高熱であるにもかかわらず、熱エネルギーを未利用のまま空中に排気される無駄が多く不経済であった。また、産業廃棄物の焼却の後には、灰の中に燃えない固形物が混入しており、これは埋立によって処分されていたが、埋立処分場が候補地を見つからないまま不足しているのが現状である。   In any case, miscellaneous waste requires high heat treatment of at least 800 ° C in order to prevent dioxin generation and kill fungi and viruses. Conventionally, it is not suitable for these solutions. To solve this problem, the fuel consumption of the heavy oil burner is enormous, and the consumption of fossil fuels that cause global warming. Furthermore, despite the high temperature of the waste gas, there is a lot of waste that is exhausted into the air without using thermal energy, which is uneconomical. In addition, after incineration of industrial waste, solids that do not burn are mixed in ash, which was disposed of by landfill, but there is a shortage of landfill sites without finding candidate sites. Is the current situation.

この発明は、上記のような実情に鑑みて、燃えない固形物が混入している殊に産業廃棄物の焼却処理とともに発電を効率的になすのに適し、合理的に燃費を低減できるとともに、環境に優しく排気でき、また、固形物を含む焼却灰類の有効利用にも適する方式の廃棄物処理発電炉を提供することを課題とした。   In view of the above circumstances, the present invention is suitable for efficiently generating power together with incineration treatment of industrial waste, in particular, containing non-combustible solids, and can rationally reduce fuel consumption, It was an object to provide a waste treatment power generation furnace that can be exhausted gently to the environment and that is suitable for effective use of incinerated ash containing solids.

上記の課題を解決するために、この発明は、傾斜する回転筒の上端に廃棄物の投入ホッパーを設け、下端にはバーナーの炎の吹込口と、廃棄物の焼却灰類の灰出口を設けたロータリーキルンを主体とし、ロータリーキルンの中の燃焼ガスが排気される排ガス口の外側に排ガス受けを設け、排ガス受けには、排気される不完全燃焼ガスを完全燃焼させる二次燃焼室を介して、発電装置と、排気をクリーン化させる集塵装置とを順次接続してあり、一方、焼却灰類の灰出口の外側には、排出される焼却灰類の冷却装置と、冷却に伴って焼却灰類から受ける熱で水を加熱する加熱水装置とを設けてあり、前記発電装置は、二次燃焼室からの排気を熱媒体に伝達する熱交換機と、熱媒体で湯を沸騰させる蒸気発生機と、その蒸気によりタービンを駆動させる発電機とからなり、蒸気発生機に蒸気化させる温水を得るよう前記加熱水装置からの配管を接続した廃棄物処理発電炉であって、ロータリーキルンの回転筒は、小径の上部回転筒とその端が突入する大径の下部回転筒とからなることにより、上部回転筒と下部回転筒との間の隙間を排ガス口として構成し、排ガス口にその周囲に被さるように前記排ガス受けが形成され、排ガス受けに連続して二次燃焼室が形成されていることを特徴とする廃棄物処理発電炉。 In order to solve the above problems, the present invention is provided with a waste injection hopper at the upper end of an inclined rotating cylinder, and provided with a burner flame inlet and an ash outlet for waste incineration ash at the lower end. The rotary kiln is mainly used, and an exhaust gas receiver is provided outside the exhaust gas outlet from which the combustion gas in the rotary kiln is exhausted. The exhaust gas receiver has a secondary combustion chamber for completely combusting the exhausted incomplete combustion gas, A power generator and a dust collector that cleans the exhaust are connected in sequence. On the other hand, on the outside of the ash outlet of the incinerated ash, a cooling device for the incinerated ash to be discharged, and incinerated ash with cooling A heating water device that heats water with heat received from a heat generator, and the power generation device includes a heat exchanger that transmits exhaust gas from the secondary combustion chamber to a heat medium, and a steam generator that boils hot water with the heat medium And the steam drives the turbine Consists of a generator for, a waste generator furnace connecting pipes from the heating water system to obtain hot water for the steam into the steam generator, the rotating cylinder of the rotary kiln, the diameter of the upper rotary cylinder that By comprising a large-diameter lower rotating cylinder with an end entering, the gap between the upper rotating cylinder and the lower rotating cylinder is configured as an exhaust gas port, and the exhaust gas receiver is formed so as to cover the exhaust gas port around it. A waste treatment power generation furnace in which a secondary combustion chamber is formed continuously with an exhaust gas receiver .

廃棄物処理発電炉を上記のように構成したから、ホッパーに投入された廃棄物は、回転筒の中をその回転で攪拌されながら下りるので、燃えるゴミばかりか燃えないゴミ等を含む雑多なゴミであっても、バーナーの炎が波及することにより最終的には完全燃焼して灰出口から焼却灰類として排出され、しかも、そこにおいて焼却灰類のうちでも特に固形物に有する多量の熱が温水を得るために加熱水装置により採取され、その熱が発電のために利用される。また、焼却灰類は、回転の攪拌により金属類などのリサイクル可能なものの選別が容易になっており、残りの灰であってもそれを再加工しやすく選別しやすいものとなっている。   Since the waste treatment power generation furnace is configured as described above, the waste thrown into the hopper descends while being agitated by the rotation in the rotating cylinder, and therefore various kinds of garbage including not only burning garbage but also non-burning garbage etc. However, when the burner flame spreads, it eventually burns completely and is discharged as incineration ash from the ash outlet. In order to obtain hot water, it is collected by a heating water device, and the heat is used for power generation. Moreover, incineration ash makes it easy to sort recyclable materials such as metals by rotating agitation, and even the remaining ash is easy to reprocess and easy to sort.

発電装置は、熱交換機、蒸気発生機、発電機とからなるものであるが、そのうち、熱交換機は、ロータリーキルンの中から排出される燃焼ガスに含まれる熱の他に、二次燃焼室においてバーナー等で加熱される熱がこれ付加されることになる。また、焼却灰類に含まれる熱は、加熱水装置からの配管を通して蒸気発生機において蒸気の発生熱として利用される。   The power generator is composed of a heat exchanger, a steam generator, and a generator. Of these, the heat exchanger is a burner in the secondary combustion chamber in addition to the heat contained in the combustion gas discharged from the rotary kiln. This heat is added by heating. Moreover, the heat contained in the incinerated ash is utilized as the heat generated by the steam in the steam generator through the piping from the heating water device.

この発明は、以上説明したように、燃えない固形物が混入している殊に産業廃棄物の焼却処理とともに発電を効率的になすのに適し、合理的に燃費を低減できるとともに、環境に優しく排気できるため、二酸化酸素の削減と、ダイオキシンの発生防止と、省エネの促進等に貢献でき、また、固形物を含む焼却灰類の有効利用にも適するので、リサイクルよっても環境の保全に貢献できるという優れた効果がある。   As described above, the present invention is suitable for efficient power generation in combination with incineration treatment of industrial waste, which is mixed with non-combustible solids, and can rationally reduce fuel consumption and is environmentally friendly. Since it can be exhausted, it can contribute to the reduction of oxygen dioxide, the prevention of dioxin generation, the promotion of energy savings, etc., and it is also suitable for the effective use of incinerated ash containing solids, so it can contribute to environmental conservation through recycling. There is an excellent effect.

廃棄物収集運搬１については、契約している各事業所や工場等をトラックで回って主に産業廃棄物を、時には燃えやすい生活廃棄物を収集し、これを中間処理場の分別作業２に回す。収集物の例としては、生ゴミや廃プラスチック類、紙くず、木屑、繊維くず、ゴムくず等の燃えるゴミのほか、金属くず、ガラスくず、コンクリートくず、陶磁器くず、がれき類、燃え殻の固形物、さらには、汚泥、廃油、動植物性残さ、感染性廃棄物、アスベスト等である。   As for waste collection and transportation 1, we mainly collect industrial waste and sometimes flammable domestic waste by trucking around contracted offices and factories, etc., and turn this into separation work 2 at the intermediate treatment plant. turn. Examples of collected items include garbage such as garbage, waste plastics, paper scraps, wood scraps, fiber scraps, rubber scraps, metal scraps, glass scraps, concrete scraps, ceramic scraps, debris, solids of burning shells, Furthermore, sludge, waste oil, animal and vegetable residues, infectious waste, asbestos and the like.

焼却燃料の抽出３については、分別作業２において、これら品目のうち、天ぷら油等の廃油をバーナーの燃料として分別し、精製してリサイクル発電の運転４に供される。図２は、リサイクル発電のための廃棄物処理発電炉Ｋの模式図であり、次に、これについて説明する。   Regarding the extraction 3 of the incinerated fuel, in the separation operation 2, of these items, waste oil such as tempura oil is separated as fuel for the burner, refined, and supplied to the operation 4 of the recycle power generation. FIG. 2 is a schematic diagram of a waste treatment power generation furnace K for recycling power generation, which will be described next.

廃棄物処理発電炉Ｋは、炉本体としての特殊なロータリーキルン１１を主体として、その排気側に排気ガスの二次燃焼室１３、発電装置１５、集塵装置１７、排気塔１９が順次装備される。また、発電装置１５にはその余熱利用の湯沸し器２１が付属し、そこから風呂２３等に給湯される。また、ロータリーキルン１１の焼却灰類の排出側には、焼却灰類の冷却装置２４および選別装置２５が設けられる。   The waste treatment power generation furnace K is mainly composed of a special rotary kiln 11 as a furnace body, and an exhaust gas secondary combustion chamber 13, a power generation device 15, a dust collecting device 17, and an exhaust tower 19 are sequentially provided on the exhaust side. . Further, the power generator 15 is provided with a hot water heater 21 using the remaining heat, and hot water is supplied from there to the bath 23 and the like. In addition, an incineration ash cooling device 24 and a sorting device 25 are provided on the incineration ash discharge side of the rotary kiln 11.

ロータリーキルン１１は、やゝ傾斜する上部回転筒２７と、下部回転筒２８とからなり、上部回転筒２７が小径に形成されることにより下部回転筒２８の端部に突っ込んでおり、両方の径の違いによりその間に排ガス口２９が設けられている。そして、該部において上部回転筒２７と下部回転筒２８との両方に跨がって排ガス受け３０が被着され、その上端が前記排気ガスの完全燃焼室１３に連続している。なお、上部回転筒２７と下部回転筒２８は、それぞれに一対ずつ環状レール３１，３１が嵌着され、それをローラ３３，３３で受けることにより回転可能となっており、また、両方に環状ギア３５が取り付けられ、モータによる駆動ギア３７がそれに噛み合って回転するようになっている。   The rotary kiln 11 is composed of an upper rotary cylinder 27 and a lower rotary cylinder 28 that are slightly inclined, and the upper rotary cylinder 27 is formed in a small diameter so as to protrude into the end of the lower rotary cylinder 28. Due to the difference, an exhaust port 29 is provided between them. And in this part, the exhaust gas receiver 30 is deposited across both the upper rotary cylinder 27 and the lower rotary cylinder 28, and the upper end thereof is continuous with the exhaust gas complete combustion chamber 13. The upper rotating cylinder 27 and the lower rotating cylinder 28 can be rotated by receiving a pair of annular rails 31 and 31 and receiving them with rollers 33 and 33, respectively. 35 is attached, and the drive gear 37 by a motor is meshed with it and rotates.

廃棄物の投入については、上部回転筒２７の上端に真ん中が抜けているキャップ３９が被さっており、ホッパー４１の灰出口がそのキャップ３９の中心部から上部回転筒２７に突っ込まれている。また、下部回転筒２８の下端には、その端口を封じる封止壁４３を設け、封止壁４３の下端に灰出口４５が形成される。また、封止壁４３の中央部には、バーナー４８の吹込口４９が設けられる。そこで、吹込口４９からバーナー４８の炎を吹き込むと、空気が同時に吸入されることによって、廃棄物が下部回転筒２８では燃焼し、上部回転筒２７では乾燥して燃焼しやすいように下部回転筒２８に送られる。   Regarding the introduction of the waste, the upper end of the upper rotary cylinder 27 is covered with a cap 39 whose middle is removed, and the ash outlet of the hopper 41 is thrust into the upper rotary cylinder 27 from the center of the cap 39. Further, a sealing wall 43 that seals the end opening is provided at the lower end of the lower rotary cylinder 28, and an ash outlet 45 is formed at the lower end of the sealing wall 43. In addition, a blowing port 49 of the burner 48 is provided in the central portion of the sealing wall 43. Therefore, when the flame of the burner 48 is blown from the blow port 49, the air is simultaneously sucked so that the waste is burned in the lower rotary cylinder 28 and dried in the upper rotary cylinder 27 so that it is easy to burn and burn. 28.

運転については、上部回転筒２７と下部回転筒２８とを回転させながら燃焼が行われるので、廃棄物が生ゴミやプラスチック等の燃えるゴミの中に金属くず、ガラスくず、コンクリートくず、陶磁器くず、がれき類が含まれていても、回転に伴う攪拌により燃えるゴミは確実に燃焼し、それが完全燃焼した灰と燃焼しない固形物が混在し、その焼却灰類が灰出口４５から放出される。なお、ロータリーキルン１１内の温度は、ダイオキシンが発生しないように、また、病原菌やウイルスを死滅させるために、常時８００°Ｃ〜１０００°Ｃの温度に保持される。   About operation, since combustion is performed while rotating the upper rotating cylinder 27 and the lower rotating cylinder 28, the waste is burnt garbage such as raw garbage and plastic, scrap metal, glass scrap, concrete scrap, ceramic scrap, Even if debris is included, the garbage burned by the agitation accompanying the rotation reliably burns, the ash that is completely burned and the solid matter that does not burn are mixed, and the incinerated ash is discharged from the ash outlet 45. The temperature in the rotary kiln 11 is always maintained at a temperature of 800 ° C. to 1000 ° C. so that dioxins are not generated and in order to kill pathogenic bacteria and viruses.

発電装置１５は、排気ガスの完全燃焼室１３から送られる高温の排気熱を水等の熱媒体に移す熱交換機１５ａと、その熱媒体で水を沸騰させる蒸気発生機１５ｂと、その蒸気でタービンを回転させる発電機１５ｃとからなるものである。そのうち、蒸気発生機１５ｂには、その蒸気の元となる熱水を供給する配管４７が接続される。また、前記した沸し器２１は、発電機１５ｃに従属し、熱交換機２１ａと貯湯タンク２１ｂとからなり、水道水が熱交換機２１ａに供給され、その水が発電機１５ｃで仕事を終わって生じた温水から熱を奪って生活温水として貯湯タンク２１ｂに蓄えられ、配管５１によって風呂２３等に供給される。   The power generator 15 includes a heat exchanger 15a that transfers high-temperature exhaust heat sent from the exhaust gas complete combustion chamber 13 to a heat medium such as water, a steam generator 15b that boiles water using the heat medium, and a turbine that uses the steam. And a generator 15c for rotating the motor. Among these, the steam generator 15b is connected to a pipe 47 for supplying hot water that is the source of the steam. Further, the above-described boiling device 21 is subordinate to the generator 15c, and includes a heat exchanger 21a and a hot water storage tank 21b, and tap water is supplied to the heat exchanger 21a, and the water is generated by finishing the work in the generator 15c. The hot water is deprived of heat and stored in the hot water storage tank 21b as hot water for daily life, and supplied to the bath 23 and the like through the pipe 51.

蒸気発生機１５ｂに配管４７により熱水を送る装置については、灰出口４５に空気による冷却装置２４が設けられているので、それで加熱された空気を水に熱交換する加熱水装置５５が設けられる。したがって、ロータリーキルン１１の内部に発生した熱エネルギーの大半が発電に利用されることになる。   As for the device for sending hot water to the steam generator 15b by the pipe 47, since the air cooling device 24 is provided at the ash outlet 45, the heated water device 55 for exchanging heat from the heated air to water is provided. . Therefore, most of the thermal energy generated in the rotary kiln 11 is used for power generation.

Underneath, the carts 57, 57 are arranged by type, and the contents of these carts 57, 57 are transported to the sorting area, where metals are collected. Incinerated ash and fine solids are pulverized and then kneaded with water. For example, they are commercialized as green bricks and shipped to the market 7 (FIG. 1). In addition, in relation to processing miscellaneous waste, it may be rare that unincinerated materials are mixed in. In this case, it is easy to burn and is made fine and sent to another small secondary incinerator.
