METHOD OF FIRE DECONTAMINATION OF HALOGEN-, SULFUR- AND PHOSPHORUS-CONTAINING ORGANIC WASTES Russian patent published in 2002 - IPC

FIELD: burning liquid wastes; chemical, petrochemical and medical industries; mechanical engineering and other industries. SUBSTANCE: method of fire decontamination of wastes includes delivery of waste and neutralizing additive to reactor and heat treatment of wastes at delivery of fuel, air and wastes to reactor; introduction of neutralizing additive is effected in way of motion of gases in two flows: one flow - alkaline-earth reagents is fed directly to zone of heat treatment at temperature of 800 to 1500 C and second flow-alkaline reagent is fed to zone of after-burning of high-temperature gaseous products of heat treatment having form of twisted cyclone jet; consumption of alkaline- earth reagents is maintained at level of 100 to 130 mass-% of stoichiometric amount and consumption of alkaline reagent is maintained at level of 20 to 30 mass-% of stoichiometric amount. Zone of heat treatment is just revolving fluidized bed. Temperature in waste heat treatment zone is maintained at level of 800 to 900 C. Heat treatment zone has form of twisted cyclone jet. Temperature in waste heat treatment zone is maintained at level of 1200 to 1500 C. EFFECT: enhanced ecological efficiency at improved economical parameters; enhanced reliability of decontamination. 6 cl, 2 ex
