In addition , the rotational direction of the flow of the low-temperature carbonized gas S after it has flowed into the dust separator 28, and the dust The direction of rotation of the flow of the low-temperature carbonized gas S before flowing out from the separation device 28 is the same. The bottom region 60 of the 0m dust separator 28 is raised in a conical or parabolic shape toward the center. therefore no dust deposits are formed.

Ｐ：焼室３４内で低温乾留ガスＳの残余流ｔ、が燃焼する際に生成された高温の 煙道ガスは廃熱ボイラ３６内で蒸気製造のために使われる。低温乾留ドラム４か ら塵埃分離装置２８、燃焼室３４、廃熱ボイラ３６及び浄化装置４２を介して低 温乾留ガスＳの残余流Ｌ２を搬送することは吸込送風機４４によって行われる。P: High-temperature gas generated when the residual flow t of the low-temperature carbonized gas S is combusted in the combustion chamber 34. The flue gas is used in waste heat boiler 36 for steam production. Low temperature carbonization drum 4? from the dust separator 28, combustion chamber 34, waste heat boiler 36 and purification device 42. Conveying the residual stream L2 of hot carbonization gas S takes place by means of a suction blower 44.

加熱ガスの製造のためには必要とされない加熱ガスｇは開ループ回路７２内を弁 ４６を通って流れ、燃焼室３４から流出した煙道ガスに浄化装置４２の前で混入 される。浄化装置４２内ではそれゆえ完全に燃焼した煙道ガスだけが浄化される 。The heated gas g, which is not needed for the production of heated gas, is routed through the open loop circuit 72 via a valve. 46 and is mixed with the flue gas exiting the combustion chamber 34 before the purifier 42 be done. In the purifier 42, therefore only completely combusted flue gases are purified. .

熱交換器８０の熱媒体として廃熱ボイラ３６で製造された蒸気が使用される。Steam produced in the waste heat boiler 36 is used as a heat medium for the heat exchanger 80.

この蒸気は加熱面３８の部位へから取出されて、熱交換器８０の部位Ａへ約３９ ０°Ｃの流入温度で供給される。熱交ＩＡ器８０の部位Ｂから流出する冷却され た蒸気は加熱面３８の部位Ｂへ約３３０°Ｃの温度で再び流入する。This steam is removed from the heating surface 38 to a portion A of the heat exchanger 80 about 39 Supplied with an inlet temperature of 0°C. Cooled water flowing out from part B of the heat exchanger IA 80 The steam then flows back into portion B of the heating surface 38 at a temperature of approximately 330°C.

加熱ガス８のより−１の塵埃減少を達成するために、送風機２０の吸込側には、 ・克出導管１４内に塵埃分離装置８２が配置されている。In order to achieve a -1 dust reduction in the heated gas 8, the suction side of the blower 20 is equipped with: - A dust separator 82 is arranged inside the extraction conduit 14.

弁２３．２５が閉しられると、低温乾留ドラム４からの加熱ガスｇは回路７２内 に導かれ、弁４９、導管４１を介して廃棄ボイラ３６の前で煙道ガスに混入され かつ弁４６を介して廃棄ボイラ３Ｇの後で煙道ガスに混入される。その場合混合 ガスの浄化は浄化装置４２内だけで行われる。今、加熱ガス回路７２は導管４７ 及び弁４８．５０を介して閉ループを形成し、その場合に熱交換器８０′が導管 ４７内に位置する。この場合、送風Ｉ！４４の吐出側では清浄な煙道ガスが取出 され、導管４７内に配置された熱交換器８０′内で予熱される。引き続いて、予 熱された煙道ガスは加熱ガスｇに再び混入される。When the valves 23.25 are closed, the heated gas g from the low temperature carbonization drum 4 flows into the circuit 72. is introduced into the flue gas before the waste boiler 36 via the valve 49 and the conduit 41. and is mixed into the flue gas after the waste boiler 3G via valve 46. In that case mixed Gas purification is performed only within the purifier 42. Now, the heating gas circuit 72 is connected to the conduit 47 and valves 48,50 to form a closed loop, in which case the heat exchanger 80' is connected to the conduit Located within 47. In this case, the ventilation I! Clean flue gas is taken out on the discharge side of 44. and preheated in a heat exchanger 80' located within conduit 47. Subsequently, the forecast The heated flue gas is mixed back into the heated gas g.

自給自足で運転可能な低温乾留プラント１は既設の燃焼プラント２に対して後か ら据付けるのに特に有利に通ずる。このためには主として導管３２を介して結合 するだけである。The low-temperature carbonization plant 1, which can be operated self-sufficiently, will be installed later than the existing combustion plant 2. This is particularly advantageous for installation. For this purpose, the connection is mainly made via the conduit 32. Just do it.
