Blast furnace bottom structure of fluidized bed incinerator

摘要

(57) Abstract Objective Past compared to reducing amount used of bed materialBlast furnace bottom structure of the fluidized bed incinerator which it is possible and at the same time can miniaturize the reactor itselfStructure is offered. Constitution Fluidization air front and back diffused air tube 18 and left and right diffused air tubeGushing from the diffused air hole 22 of 20, it fluidizes bed material 5Due to especially front and back diffused air tube the upper part of 18 and left and right diffused air tube 20To form fluid bed 23, at inside the said fluid bed 23 suffering of the rubbish and the likeWhen burnup ones it burns up with aforementioned bed material 5 and suspension state, aforementionedAt fluid bed 23 cannot be burnt up noncombustible 10 the metal piece and the like which flowTo sink to fluid bed 23 lower part with the moving state, tilt of hull angle section 13To be moved to left and right inclined section 14,14 by diagonal, furthermore the said leftWith inclination of dextral inclined section 14,14 noncombustible extraction channel 16To be gathered, moving bed 24 inside the said noncombustible extraction channel 16Falling, it is extracted from noncombustible extraction opening 15.
