The invention provides a
system for calcining treatment and
resource utilization of
sugar-making filter mud. The
system comprises a pulverized
coal preparation
system, a feeding system, a calcining system, a
waste heat recovery system, a
flue gas environment-friendly up-to-standard emission
treatment system and a quick
lime recovery system,
Raw material coal is prepared into pulverized
coal as auxiliary fuel, crude
sugar filter mud is crushed, the pulverized coal and the crude
sugar filter mud are simultaneously added into a calcining furnace, ash generated after calcining is discharged and cooled to serve as a quick
lime material;
flue gas generated after
calcination enters a
waste heat boiler to be subjected to heat recycling, saturated steam is generated, the
flue gas obtained after heat exchange enters a denitration device to be subjected to denitration treatment, the
flue gas obtained after denitration exchanges heat with air and then is subjected to dust removal, and clean
flue gas is obtained; and air heated by the
flue gas is introduced into the calcining furnace as
combustion-supporting air, so that the temperature of the
combustion-supporting air entering the calcining furnace is integrally increased. Reduction and harmless treatment of the sugar-making filter mud are achieved, meanwhile, quick
lime generated in the high-temperature
calcination process, namely the high-temperature
decomposition reaction process, is recycled to achieve the purpose of
resource utilization, high-temperature flue gas
waste heat generated in
calcination is recycled to generate saturated steam, and the purpose of
energy conservation in the environment-friendly treatment process is achieved.
