Moving grate drying bed-circulating fluidized bed boiler-compounded incineration equipment

Abstract

The invention provides moving grate drying bed-circulating fluidized bed boiler-compounded incineration equipment, which comprises a moving grate drying bed and a circulating fluidized bed boiler, wherein the moving grate drying bed comprises a feed system arranged on the moving grate drying bed; the circulating fluidized bed boiler comprises a dreg outlet formed in the bottom of a furnace of the circulating fluidized bed boiler; and the moving grate drying bed is connected with the circulating fluidized bed boiler in a dense phase zone of the moving grate drying bed. The moving grate drying bed-circulating fluidized bed boiler-compounded incineration equipment realized by the invention is reasonable and scientific in design, can be used for processing dregs with the characteristics of low heat value, high moisture content and poor air permeability, and can be further used for processing municipal solid wastes with the similar characteristics.

Description

technical field [0001] The patent of the present invention relates to a movable grate-circulating fluidized bed composite incineration equipment, in particular to a new type of movable grate-circulating fluidized bed composite incineration device with a diversion device for treating medicinal dregs. Background technique [0002] As more and more pharmaceutical factories are built and put into use, the amount of dregs produced by pharmaceutical factories in my country will also increase. Antibiotic dregs have been included in the list of hazardous waste, and their disposal methods are also in accordance with hazardous waste management regulations. At present, domestic medicinal residues are mostly disposed of in safe landfills, which is not only difficult to achieve the goals of reduction, recycling, and harmlessness, but also occupies land, requires high disposal costs, and is difficult to find the site of the plant. At present, only a few cities in my country, such as Shenz...
