If power from the outside or power from the steam turbine generator 14 cannot be received due to some accident or the like, the push-in blower 26 and the induction blower 16 are controlled by the steam turbines 26b and 16b. Normally driven for rotation for about 5 minutes. However, since the amount of steam generated by the waste heat boiler is reduced, it is difficult to perform normal rotation for more than 2 to 5 minutes only by driving the steam turbine. Therefore, the emergency power generator 32 is automatically started up within 5 to 40 seconds after the power cannot be received, and the switching device 33 is switched to the emergency power generator 3.
Automatically switched to 2 side. The emergency power generator 32
After the switching to the side, the steam turbines 26b, 16b and the induction motors 26a, 16a are operated in parallel, so that the driving force of the steam is reduced by the driving force of the motors 26a, 16b, while the push-in blower 26 and the induction fan are used. Each of the ventilators 16 is maintained in a steady operation state.

When the switchgear 33 is switched to the emergency power generator 32 during a power outage, equipment that needs to be operated in order to ensure the safety of the plant (for example, a boiler feed pump, a forced air blower 26, a pyrolysis drum, etc.) The power supply to all the components other than the emergency rotation drive device 38, the pyrolysis gas burner control device 36, and the induced draft fan 16) is cut off.

On the other hand, when the emergency power generation device 32 is started, power is supplied from the emergency power generation device 32 to the emergency rotation drive device 38 of the thermal decomposition drum 2 as described above. The rotation state can be switched to a low-speed rotation state of about 0.1 to 0.2 rpm because it is necessary to prevent a large expansion and contraction of itself. Further, at the time of a power failure, power is supplied from the uninterruptible power supply device 35 to the pyrolysis gas burner control device 36 until the emergency power generation device 32 is started. Therefore, the pyrolysis gas burner does not go into a fire extinguishing state.

Further, at the time of a power failure, the supply device 1 of the waste C to the pyrolysis drum other than the emergency load and the circulation fan 20 to the hot air generating furnace 12 are stopped, so that the generation amount of the pyrolysis gas G is also reduced. Decreases gradually. As a result, as the amount of steam generated in the waste heat boiler 7 decreases, the power consumption of the push-in blower 26 and the induction blower 16 increases, but as described above, the amount of generated pyrolysis gas G itself decreases. In addition, the power consumption of the forced air blower 26 and the induction blower 16 is significantly reduced as compared with the power consumption during the steady operation, so that the emergency power generator 32 can be small.

According to the present invention, the thermal decomposition drum 2 is rotated at an extremely low speed by the emergency generator 32 at the time of a power failure, and the push-in blower 26 and the induction blower 16 are driven in combination by the steam turbines 26b, 16b. I have. As a result, the operation of the dry distillation pyrolysis melting and burning device can be stopped safely and smoothly at the time of a power failure with a relatively small-sized emergency power generator without requiring a large-capacity emergency power generator. The pyrolysis gas G generated by the residual heat after the power failure can also be completely burned, and environmental pollution caused by release of unburned substances and bad smell to the outside can be completely prevented.
