Waste incineration facility

Abstract

The waste incineration facility includes a waste pit for receiving waste and an incinerator for incinerating the waste stored in the waste pit. The waste incineration facility further includes: a fermentation dryer configured to ferment and dry the waste while heating the waste to a predetermined temperature range under reduced pressure; and a storage hopper configured to store a fermented dried product produced in the fermentation dryer. The fermented dried product stored in the storage hopper is charged into the incinerator to incinerate the fermented dried product. The waste incineration facility further includes: a first conveyor connecting the waste pit and the fermentation dryer; and a second conveyor connecting the fermentation dryer and the storage hopper. The first conveyor and the second conveyor are driven to continuously perform production of the fermented dried product from the waste in the waste pit and storage of the fermented dried product in the storage hopper.

1 . A waste incineration facility including a waste pit for receiving waste and an incinerator for incinerating the waste stored in the waste pit, the waste incineration facility comprising:
 a fermentation dryer configured to ferment and dry the waste while heating the waste to a predetermined temperature range under reduced pressure; and   a storage hopper for storing a fermented dried product produced in the fermentation dryer,   wherein   the waste incineration facility is configured such that the fermented dried product stored in the storage hopper is charged into the incinerator and the fermented dried product is incinerated.   
     
     
         2 . The waste incineration facility of  claim 1 , further comprising:
 a first conveyor connecting the waste pit and the fermentation dryer; and a second conveyor connecting the fermentation dryer and the storage hopper,   wherein   the waste incineration facility is configured such that the first conveyor and the second conveyor are driven to continuously perform the production of the fermented dried product from the waste in the waste pit and the storage of the fermented dried product in the storage hopper.   
     
     
         3 . The waste incineration facility of  claim 2 , further comprising:
 a boiler configured to recover heat of exhaust gas generated by combustion of the fermented dried product in a combustion chamber of the incinerator,   wherein   the boiler and the fermentation dryer are connected to each other by a steam supply path, and   the waste incineration facility is configured such that steam generated in the boiler is supplied to the fermentation dryer through the steam supply path and used to heat the waste.   
     
     
         4 . The waste incineration facility of  claim 3 , wherein
 the fermentation dryer includes: a sealed container having a storage for storing the waste, a waste inlet, and an outlet; a charge pipe connecting a downstream end of the first conveyor and the waste inlet; and a discharge pipe connecting the outlet and an upstream end of the second conveyor,   the charge pipe is provided with a first charge valve, a second charge valve, and a charge-side temporary reservoir provided between the first charge valve and the second charge valve,   the discharge pipe is provided with a first discharge valve, a second discharge valve, and a discharge-side temporary reservoir provided between the first discharge valve and the second discharge valve,   the first charge valve, the second charge valve, the first discharge valve, and the second discharge valve are controlled by a valve controller, and   the waste incineration facility is configured such that the waste is charged into the storage based on control by the valve controller so that only one of the first charge valve or the second charge valve is opened, and the fermented dried product is discharged from the storage based on control by the valve controller so that only one of the first discharge valve or the second discharge valve is opened.   
     
     
         5 . The waste incineration facility of  claim 3 , further comprising:
 a steam control device configured to control an amount of the steam supplied to the fermentation dryer,   wherein   the steam control device includes: a conveyer speed adjuster configured to adjust conveyance speeds of the first conveyor and the second conveyor; and a furnace charge amount adjuster configured to adjust a charge amount of the fermented dried product from the storage hopper into the combustion chamber of the incinerator.   
     
     
         6 . The waste incineration facility of  claim 4 , further comprising:
 a steam control device configured to control an amount of the steam supplied to the fermentation dryer,   wherein   the steam control device includes: a conveyer speed adjuster configured to adjust conveyance speeds of the first conveyor and the second conveyor; and a furnace charge amount adjuster configured to adjust a charge amount of the fermented dried product from the storage hopper into the combustion chamber of the incinerator.
