The invention discloses an integral
sludge incineration system for a circulating
fluidized bed, which includes an incinerator, a separator, a pneumatic distribution valve, a
drying machine, a fine ashseparator, a condenser, a steam and water separator, a first blower, a
tail heating surface, a dust remover, an induced draft fan and a
chimney, wherein the upper part of the incinerator is connectedwith the separator and the
tail heating surface respectively; the lower part of the separator is connected with the incinerator and the
drying machine respectively through the pneumatic distributionvalve; dried
sludge in the incinerator sequentially passes by the fine ash separator, the condenser and the steam and water separator, and then is conveyed into the incinerator under the action of thefirst blower; the
tail heating surface is connected with the
drying machine through circulating conduction oil, and high temperature
flue gas inside the tail heating surface passes by the dust remover, and then is discharged from the
chimney under the action of the induced draft fan. According to the invention,
sludge drying and
incineration are organically integrated, so that consumption of auxiliary fuel during
sludge incineration is greatly reduced, and the drying and
incineration technology is greatly simplified; and the
system has the characteristics of simple operation, wide adjusting range,
good control performance, low production cost, and the like.
