特開２０１６−１８０５２８号公報Japanese Unexamined Patent Publication No. 2016-180528 特許第４８３１３０９号公報Japanese Patent No. 4831309

一般に廃棄物処理設備では、押込み送風機以外に排ガスを煙突に向けて引き込み誘引送風機を備えて平衡通風方式によって排ガス経路を負圧に維持している。 In general, waste treatment equipment is equipped with an induction blower that draws exhaust gas toward the chimney in addition to the push-in blower, and maintains the exhaust gas path at a negative pressure by a balanced ventilation method.

特許文献１に記載したような過給機を用いて押込み送風機による動力コストを削減することに加えて、誘引送風機による動力コストを削減するために過給機を用いることも望まれている。 In addition to reducing the power cost of the indentation blower by using the supercharger as described in Patent Document 1, it is also desired to use the supercharger in order to reduce the power cost of the attraction blower.

本発明の目的は、上述した従来技術に鑑み、誘引送風機による動力コストを削減することが可能な廃棄物処理設備及び廃棄物処理設備の運転方法を提供する点にある。 An object of the present invention is to provide a waste treatment facility and an operation method of the waste treatment facility capable of reducing the power cost of the attracting blower in view of the above-mentioned prior art.

上述の目的を達成するため、本発明による廃棄物処理設備の第一特徴構成は、廃棄物を熱処理する熱処理炉と、前記熱処理炉で発生した排ガスを熱源とする熱交換器と、タービンとコンプレッサとを備える過給機と、を有する廃棄物処理設備であって、前記熱交換器で供熱した排ガスが前記コンプレッサに流入し、前記コンプレッサから流出した排ガスが前記熱交換器で受熱した後に、前記タービンに流入するように排ガス案内経路が構成されている点にある。 In order to achieve the above object, the first characteristic configuration of the waste treatment facility according to the present invention is a heat treatment furnace for heat-treating waste, a heat exchanger using exhaust gas generated in the heat treatment furnace as a heat source, a turbine and a compressor. A waste treatment facility including a supercharger and a heat exchanger, wherein the exhaust gas supplied by the heat exchanger flows into the compressor, and the exhaust gas flowing out of the compressor receives heat in the heat exchanger. The point is that the exhaust gas guide path is configured so as to flow into the turbine.

コンプレッサから流出した排ガスが熱交換器に送られて排ガスの保有熱と熱交換された後にタービンに流入することにより、コンプレッサが回転駆動されることで煙道の排ガスがコンプレッサに引き込まれるようになる。タービンで熱エネルギーが低下した排ガスはタービンから流出した後に排気される。 The exhaust gas flowing out of the compressor is sent to the heat exchanger, and after heat exchange with the heat held by the exhaust gas, it flows into the turbine, and the exhaust gas from the flue is drawn into the compressor by rotating the compressor. .. Exhaust gas whose thermal energy has decreased in the turbine is exhausted after flowing out of the turbine.

同第二の特徴構成は、上述の第一の特徴構成に加えて、誘引送風機を更に備え、前記誘引送風機により前記熱交換器で供熱した排ガスを誘引して前記コンプレッサ、または、前記熱交換器の受熱側の何れかに送風する誘引送風経路を備えている点にある。 In the second characteristic configuration, in addition to the first characteristic configuration described above, an attractive blower is further provided, and the exhaust gas supplied by the heat exchanger is attracted by the attractive blower to attract the exhaust gas to the compressor or the heat exchange. The point is that it has an attractive air passage that blows air to either side of the heat receiving side of the vessel.

過給機が機能しない廃棄物処理設備の立上げなどに誘引送風機を補助的に用いて煙道の排ガスを誘引してコンプレッサに導き、或いは煙道の排ガスを熱交換器の受熱側に直接的に送風することで、炉内を負圧に維持しながら立ち上げることができる。 An inducer blower is used as an auxiliary to attract the exhaust gas from the flue and guide it to the compressor, or the exhaust gas from the flue is directed directly to the heat receiving side of the heat exchanger, such as when starting up a waste treatment facility where the supercharger does not work. By blowing air into the furnace, it is possible to start up while maintaining the inside of the furnace at a negative pressure.

同第三の特徴構成は、上述の第一または第二の特徴構成に加えて、排ガスを熱源として前記熱処理炉の燃焼用空気を予熱する空気予熱器を更に備え、排ガスの流れに従って上流側に前記空気予熱器が配され、下流側に前記熱交換器が配されている点にある。 In addition to the above-mentioned first or second characteristic configuration, the third characteristic configuration further includes an air preheater that preheats the combustion air of the heat treatment furnace using the exhaust gas as a heat source, and moves upstream in accordance with the flow of the exhaust gas. The point is that the air preheater is arranged and the heat exchanger is arranged on the downstream side.

排ガスの保有熱を有効に利用して全体として動力コストを低減して経済性に富んだ操炉が可能になる。 By effectively utilizing the heat possessed by the exhaust gas, the power cost can be reduced as a whole, and the furnace can be operated economically.

本発明による廃棄物処理設備の運転方法の第一特徴構成は、廃棄物を熱処理する熱処理炉と、前記熱処理炉で発生した排ガスを熱源とする熱交換器と、タービンとコンプレッサとを備える過給機と、を有する廃棄物処理設備の運転方法であって、前記熱交換器で供熱した排ガスを前記コンプレッサに導き、前記コンプレッサから流出した排ガスを、前記熱交換器に導いて受熱した後に前記タービンに導く点にある。 The first characteristic configuration of the operation method of the waste treatment facility according to the present invention is a supercharging including a heat treatment furnace for heat-treating waste, a heat exchanger using exhaust gas generated in the heat treatment furnace as a heat source, and a turbine and a compressor. A method of operating a waste treatment facility having a machine, wherein the exhaust gas supplied by the heat exchanger is guided to the compressor, and the exhaust gas flowing out of the compressor is guided to the heat exchanger to receive heat, and then the above. It is at the point of leading to the turbine.

以上説明した通り、本発明によれば、誘引送風機による動力コストを削減することが可能な廃棄物処理設備及び廃棄物処理設備の運転方法を提供することができるようになった。 As described above, according to the present invention, it has become possible to provide a waste treatment facility and an operation method of the waste treatment facility capable of reducing the power cost of the attracting blower.

以下、本発明による廃棄物処理設備及び廃棄物処理設備の運転方法を説明する。
図１に示すように、廃棄物処理設備１０は、廃棄物を熱処理する熱処理炉と、熱処理炉で発生した排ガスを熱源とする熱交換器と、タービンＴとコンプレッサＣとを備える過給機１などを備えている。 Hereinafter, the waste treatment equipment and the operation method of the waste treatment equipment according to the present invention will be described.
As shown in FIG. 1, the waste treatment facility 10 includes a heat treatment furnace for heat-treating waste, a heat exchanger using exhaust gas generated in the heat treatment furnace as a heat source, and a supercharger 1 including a turbine T and a compressor C. And so on.

熱処理炉としてストーカ炉、流動床炉、表面溶融炉など廃棄物を熱処理する任意の炉を採用することができる。以下、熱処理炉として流動床式の焼却炉を採用した例を説明する。 As the heat treatment furnace, any furnace for heat-treating waste such as a stoker furnace, a fluidized bed furnace, and a surface melting furnace can be adopted. Hereinafter, an example in which a fluidized bed incinerator is used as the heat treatment furnace will be described.

焼却炉で生じた燃焼排ガス(exhaust combustion gas (c.e.))は、煙道に沿って配された空気予熱器などの熱交換器を介して保有熱が回収され、排ガス処理設備によって浄化された後に過給機１を経由して煙突ｅから排気される。 Exhaust combustion gas (ce) generated in an incinerator is collected by a heat exchanger such as an air preheater arranged along the chimney, and after being purified by an exhaust gas treatment facility. It is exhausted from the chimney e via the supercharger 1.

空気予熱器では、押込み送風機Ｆ１により供給された燃焼用空気が排ガスの保有熱との間で熱交換され、予熱された後に焼却炉に供給される。空気予熱器から流下する排ガスは、さらに熱交換器が組み込まれた排ガス処理設備で浄化される。排ガス処理設備には、ばいじんを除去するバグフィルタ、ＳＯｘやＨＣｌなどを除去する洗煙装置などが含まれる。 In the air preheater, the combustion air supplied by the indentation blower F1 is heat-exchanged with the retained heat of the exhaust gas, preheated, and then supplied to the incinerator. The exhaust gas flowing down from the air preheater is further purified by an exhaust gas treatment facility incorporating a heat exchanger. Exhaust gas treatment equipment includes a bug filter that removes soot and dust, a smoke washing device that removes SOx, HCl, and the like.

熱交換器で供熱し、煙道を流下した排ガスはダクトｄ１を介してコンプレッサＣに流入し、コンプレッサＣから流出した排ガスはダクトｄ２を介して熱交換器に導かれ、熱交換器で受熱した後にダクトｄ３を介してタービンＴに流入するように排ガス案内経路が構成されている。タービンＴから流出した排ガスはダクトｄ４を介して煙突ｅに導かれ、煙突ｅから排気される。 The exhaust gas supplied by the heat exchanger and flowing down the flue flows into the compressor C through the duct d1, and the exhaust gas flowing out from the compressor C is guided to the heat exchanger through the duct d2 and receives heat by the heat exchanger. After that, the exhaust gas guide path is configured so as to flow into the turbine T through the duct d3. The exhaust gas flowing out of the turbine T is guided to the chimney e through the duct d4 and exhausted from the chimney e.

従来の廃棄物処理設備１０で湿式の洗煙装置の後段で排ガスを加熱処理するために用いられていた白煙防止ファン及び誘引ファンの機能が上述の過給機１で代替される。 The above-mentioned supercharger 1 replaces the functions of the white smoke prevention fan and the attraction fan used for heat-treating the exhaust gas in the subsequent stage of the wet smoke washing device in the conventional waste treatment facility 10.

過給機１に備えたコンプレッサＣで煙道から引き抜いた排ガスを熱交換器で加熱し、加熱した排ガスをタービンＴに入力することで過給機１の駆動力が得られる。なお、タービンＴの入口圧力とコンプレッサＣの出口圧力とほぼ等しい値に設定される。 The driving force of the supercharger 1 is obtained by heating the exhaust gas drawn from the flue by the compressor C provided in the supercharger 1 with the heat exchanger and inputting the heated exhaust gas to the turbine T. The inlet pressure of the turbine T and the outlet pressure of the compressor C are set to substantially equal values.

例えば、コンプレッサＣの入口温度を２０〜５０℃、タービンＴの入口温度を３５０〜５５０℃とする場合に、排ガス経路を負圧にして、流動床炉内を−０．５〜１ｋＰａ（Ｇ）、過給機１の入口圧力＝コンプレッサＣの入口圧力≒−５〜−１０ｋＰａ（Ｇ）、コンプレッサＣの出口圧力≒１５０〜５００ｋＰａ（Ｇ）、過給機１の出口圧力＝タービンＴの出口圧力≒＋０．１〜１ｋＰａ（Ｇ）で運転することができる。 For example, when the inlet temperature of the compressor C is 20 to 50 ° C. and the inlet temperature of the turbine T is 350 to 550 ° C., the exhaust gas path is set to a negative pressure and the inside of the fluidized bed furnace is −0.5 to 1 kPa (G). , Inlet pressure of turbocharger 1 = inlet pressure of compressor C ≒ -5 to -10 kPa (G), outlet pressure of compressor C ≈ 150 to 500 kPa (G), outlet pressure of turbocharger 1 = outlet pressure of turbine T It can be operated at ≈ + 0.1 to 1 kPa (G).

図２に示すように、排ガス案内経路の圧力を調整するために、煙道からコンプレッサＣの入口までのダクトｄ１に吸込みダンパｄｕ１を設けることができる。 As shown in FIG. 2, a suction damper du1 can be provided in the duct d1 from the flue to the inlet of the compressor C in order to adjust the pressure in the exhaust gas guide path.

また、図３に示すように、排ガス案内経路の圧力を調整するために、コンプレッサＣの出口ガスの一部をダクトｄ４にバイパスするダクトｄ２１を設けるとともに、当該ダクトｄ２１にダンパｄｕ２を設けて、ダンパｄｕ２の開度を調整することも可能である。ダンパｄｕ２がバイパス弁として機能する。 Further, as shown in FIG. 3, in order to adjust the pressure in the exhaust gas guide path, a duct d21 that bypasses a part of the outlet gas of the compressor C to the duct d4 is provided, and a damper du2 is provided in the duct d21. It is also possible to adjust the opening degree of the damper du2. The damper du2 functions as a bypass valve.

誘引送風機Ｆ２を更に備え、誘引送風機Ｆ２により熱交換器で供熱した排ガスを誘引してコンプレッサＣ、または、熱交換器の受熱側の何れかに送風する誘引送風経路を備えていることが好ましい。 It is preferable that the attracting blower F2 is further provided, and the attracting blower path for attracting the exhaust gas supplied by the heat exchanger by the attracting blower F2 and blowing the exhaust gas to either the compressor C or the heat receiving side of the heat exchanger is provided. ..

図４に示すように、煙道からコンプレッサＣの入口に到るダクトｄ１に誘引送風機Ｆ２を備えることにより、過給機１が機能しない廃棄物処理設備１０の立上げ時などに誘引送風機Ｆ２を補助的に用いて煙道の排ガスを誘引してコンプレッサＣに導くことで、円滑に廃棄物処理設備１０を立ち上げることができる。なお、過給機１が立上った後には誘引送風機Ｆ２を停止すればよく、過給機１が非常停止したような非常の場合には、炉が停止するまでの間は誘引送風機Ｆ２を用いて操炉状態を維持することができる。 As shown in FIG. 4, by providing the attracting blower F2 in the duct d1 from the flue to the inlet of the compressor C, the attracting blower F2 can be installed at the time of starting up the waste treatment facility 10 in which the supercharger 1 does not function. By attracting the exhaust gas from the flue and guiding it to the compressor C by using it as an auxiliary, the waste treatment facility 10 can be started up smoothly. After the turbocharger 1 has started up, the induction blower F2 may be stopped, and in an emergency such as when the supercharger 1 has stopped in an emergency, the attraction blower F2 should be stopped until the furnace is stopped. It can be used to maintain the operating state.

補助的な誘引送風機Ｆ２と過給機１を直列に配置して、過給機１の駆動状態に合わせて誘引送風機Ｆ２を制御することにより排ガスの引き抜き状態(炉内圧)を調整することができる。また、誘引送風機Ｆ２を設けていない場合には、過給機１が駆動力を得るまでは押込送風機Ｆ１による送風に依るため、排ガス経路は正圧となるが、誘引送風機Ｆ２を設けると始動開始から排ガス経路を負圧にすることができる。 By arranging the auxiliary attracting blower F2 and the supercharger 1 in series and controlling the attracting blower F2 according to the driving state of the supercharger 1, the exhaust gas extraction state (in-furnace pressure) can be adjusted. .. Further, when the attract blower F2 is not provided, the exhaust gas path becomes a positive pressure because the blower is blown by the push blower F1 until the supercharger 1 obtains the driving force, but the start starts when the attract blower F2 is provided. The exhaust gas path can be made negative pressure.

図５に示すように、補助的な誘引送風機Ｆ２と過給機１を並列に配置して、過給機１が機能しない廃棄物処理設備の立上げなどに誘引送風機Ｆ２を補助的に用いて煙道の排ガスを熱交換器の受熱側に直接的に送風することで、炉内を負圧に維持しながら立ち上げることができる。過給機１が立上ると誘引送風機Ｆ２を停止すればよい。 As shown in FIG. 5, the auxiliary flue blower F2 and the supercharger 1 are arranged in parallel, and the flue blower F2 is used as an auxiliary for starting up a waste treatment facility in which the supercharger 1 does not function. By blowing the exhaust gas from the flue directly to the heat receiving side of the heat exchanger, it is possible to start up while maintaining the inside of the furnace at a negative pressure. When the turbocharger 1 starts up, the induction blower F2 may be stopped.

そのために、煙道からコンプレッサＣの入口までのダクトｄ１に、誘引送風機Ｆ２を介して排ガスを熱交換器に導く送風ダクトｄ１１を分岐接続し、煙道から送風ダクトｄ１１の分岐部までの間、分岐部からコンプレッサＣの入口までの間、送風ダクトｄ１１のうち誘引送風機Ｆ２の上流側に其々ダンパｄｕ１，ｄｕ３，ｄｕ４を設けて、送風ダクトｄ１１を経由して熱交換器に到る経路と、ダクトｄ１を介して、コンプレッサＣに流入し、コンプレッサＣからダクトｄ２を経由して熱交換器に到る経路との経路切替可能に構成されている。 Therefore, a blower duct d11 that guides the exhaust gas to the heat exchanger via the attraction blower F2 is branched and connected to the duct d1 from the flue to the inlet of the compressor C, and between the flue and the branch portion of the blower duct d11. From the branch portion to the inlet of the compressor C, dampers du1, du3, and du4 are provided on the upstream side of the attraction blower F2 in the blower duct d11, respectively, and the path to the heat exchanger via the blower duct d11 is provided. , It is configured so that the path can be switched from the path that flows into the compressor C via the duct d1 and the path that reaches the heat exchanger from the compressor C via the duct d2.

なお、図５の態様では、過給機１が故障した場合に、誘引送風機Ｆ２のみで廃棄物処理設備の稼働状態を維持できる。その際には、ダクトｄ３に備えたダンパｄｕ５を閉塞して、ダンパｄｕ６を介して煙突ｅまで排ガスをバイパスさせることになる。 In the aspect of FIG. 5, when the supercharger 1 fails, the operating state of the waste treatment facility can be maintained only by the attracting blower F2. In that case, the damper du 5 provided in the duct d3 is closed, and the exhaust gas is bypassed to the chimney e via the damper du 6.

何れの態様であっても、排ガスを熱源として熱処理炉の燃焼用空気を予熱する空気予熱器を更に備え、排ガスの流れに従って上流側に空気予熱器が配され、下流側に熱交換器が配されているため、排ガスの保有熱を有効に利用して全体として動力コストを低減して経済性に富んだ操炉が可能になる。 In either embodiment, an air preheater for preheating the combustion air of the heat treatment furnace using the exhaust gas as a heat source is further provided, an air preheater is arranged on the upstream side according to the flow of the exhaust gas, and a heat exchanger is arranged on the downstream side. Therefore, the heat possessed by the exhaust gas can be effectively used to reduce the power cost as a whole and enable economical operation of the furnace.

以上説明したように、本発明による廃棄物処理設備の運転方法は、廃棄物を熱処理する熱処理炉と、熱処理炉で発生した排ガスを熱源とする熱交換器と、タービンとコンプレッサとを備える過給機と、を有する廃棄物処理設備の運転方法であって、熱交換器で供熱した排ガスをコンプレッサに導き、コンプレッサから流出した排ガスを、熱交換器に導いて受熱した後にタービンに導くように構成されている。 As described above, the operation method of the waste treatment facility according to the present invention includes a heat treatment furnace for heat-treating waste, a heat exchanger using exhaust gas generated in the heat treatment furnace as a heat source, and a supercharging including a turbine and a compressor. A method of operating a waste treatment facility that has a machine, so that the exhaust gas supplied by the heat exchanger is guided to the compressor, and the exhaust gas that flows out of the compressor is guided to the heat exchanger to receive heat and then to the turbine. It is configured.

上述した実施形態は、何れも本発明の一例であり、当該記載により本発明が限定されるものではなく、各部の具体的構成は本発明の作用効果が奏される範囲で適宜変更設計可能であることはいうまでもない。 The above-described embodiments are all examples of the present invention, and the description does not limit the present invention, and the specific configuration of each part can be appropriately modified and designed within the range in which the effects of the present invention are exhibited. Needless to say, there is.
