Basicity of the burned ash, management manner and its system of heavy metal concentration

摘要

Topic Basicity of the burned ash which melting treats, basicity of the burned ash which can manage heavy metal concentration securely, the management system of heavy metal concentration is offered. SolutionsBasicity of portion of the burned ash of the waste K _{m which} is discharged from incinerator 11 and the ash storage device it is discharged from each one of the ash depot of 4 which has the multiple ash depots which store the burned ash which is carried out from the burned ash analytical instrument 2 which analyzes heavy metal concentration and screw conveyer 3 and this ash storage device, 4 basicity it was required by the analysis by aforementioned burned ash analytical instrument 2 and the burned ash sending back device it satisfies heavy metal concentration 6 which sends back the burned ash which among heavy metal concentrations at least one side does not satisfy condition to incinerator 11 and basicity togetherThe burned ash feeder 8 which supplies the burned ash to melting reactor 14 the empty it constitutes.
