WASTE MATERIAL TREATMENT SYSTEM, AND FLUIDIZED BED TYPE INCINERATOR USED IN WASTE MATERIAL TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To eliminate a useless operation feeding cooling water in order to perform control if a furnace bed temperature in an incinerator and perform a treatment of sludge while an efficient bed temperature control is being carried out. ;SOLUTION: In a waste material treatment system in which sledges and condensed sludge 3 produced after treatment contaminated water are concurrently ignited at an incinerator, as cooling liquid for restricting an increasing of bed temperature in the incinerator 1, condensed sludge is fed directly into the incinerator 1 without dehydrating water and the sludge is ignited together with sludges while the bed temperature being controlled. The incinerator 1 is composed of a main body 10 of the incinerator having a fluidized bed 11 composed of a sand layer, a temperature sensor 7 for sensing a temperature of the fluidized bed 11, a sludge pressure feeding pump P driven in response to a detected signal of the temperature sensor 7, and sludge feeding nozzle 2 fixed to the main body 10 of the incinerator to feed sludge into the fluidized bed 11 and communicated with and connected to the sludge accumulating tank 4 through a sludge pressure feeding pump P.;COPYRIGHT: (C)1997,JPO
