METHOD AND EQUIPMENT FOR TREATING PAPER MAKING SLUDGE

摘要

PROBLEM TO BE SOLVED: To efficiently and economically recover ash content by suppressing decomposition of calcium carbonate to be a main component of a filler, while improving whiteness by promoting decomposition and combustion of sufficient organic components when reusing burned ash obtained by burning the paper making sludge as the filler of white pigment for paper making, etc. SOLUTION: This equipment for processing the paper making sludge S is provided with an incinerator 1 to burn and process the paper making sludge S. At least the inside of the incinerator 1 can be held under air pressure higher than atmospheric pressure. The paper making sludge S is burned and processed under the air pressure higher than atmospheric pressure. COPYRIGHT: (C)2004,JPO
