Abstract

The invention relates to the technical field of harmless disposal of an industrial organic waste, in particular to a fluidized bed incinerator for a special waste. The fluidized bed incinerator for the special waste comprises a fluidized bed incinerator body, a heating device, a flue, a steam boiler and a rapid cooling device, wherein the heating device comprises an oil gun connected to a dilute-phase zone of the body; a temperature controller for controlling the heating device is arranged in the dilute-phase zone of the body; the rapid cooling device comprises a fluid atomizing spray gun mounted on the flue corresponding to the back section of the steam boiler; a gun head of the fluid atomizing spray gun is positioned inside the flue; the spray gun is connected with a water tank through a water pipe; a water pump is arranged on the water pipe. Through arrangement of the heating device in the dilute-phase zone of the incinerator, the temperature in the dilute-phase zone of the incinerator is controlled to be above 1100 DEG C, so that the special waste is completely incinerated in the dilute-phase zone of the fluidized bed incinerator; the rapid cooling device is mounted in the flue corresponding to the back section of the steam boiler, so that flue gas is rapidly cooled to be 200 DEG C, and thus the secondary environment pollution caused by dioxin production is prevented.

Description

technical field [0001] The invention relates to the technical field of harmless industrial organic waste, in particular to a special waste fluidized bed incinerator. Background technique [0002] As a typical fast reactor, the fluidized bed has the characteristics of wide fuel adaptability, high combustion efficiency, and low nitrogen oxide emissions. As early as the 1980s, the Institute of Thermal Engineering of Zhejiang University began to engage in the research of solid waste fluidized bed incineration technology, and has formed a set of distinctive solid waste fluidized bed incineration technology, especially suitable for incineration petrochemical industry Waste residue from cogeneration. The waste slag produced in the petrochemical industry has the characteristics of high moisture, low calorific value, and small particle size, and it is difficult to incinerate with other furnace types. According to its unique design, the special fluidized bed incinerator solves the p...
