Phenolic wastewater and gasified waste coke mixed burning system

Abstract

The invention discloses a phenolic wastewater and gasified waste coke mixed burning system, and belongs to the technical field of environment science and technology three wastes treatment and comprehensive utilization. A smoke outlet of a circulating fluidized bed incineration boiler is communicated with a cyclone separator, the upper end of the cyclone separator is communicated with a secondary combustion chamber, the lower end of the cyclone separator is communicated with a return feeder, the return feeder is connected with a material loosening and feeding draught fan, and communicates withthe circulating fluidized bed incineration boiler, the secondary combustion chamber is communicated with a high-temperature smoke cooling chamber, the side end of the high-temperature smoke cooling chamber is communicated with a boiler body convection bank, the boiler body convection bank is communicated with a cloth bag dust remover through a pipeline, and the cloth bag dust remover is communicated with a chimney through an induced draft fan and a pipeline. Phenolic wastewater and gasified waste coke powder physical and chemical properties are sufficiently considered, pulverized coal and phenolic wastewater are sufficiently decomposed and combusted in an incinerator, harmless, weight reduction and resource treatment of waste can be sufficiently achieved, and the system is an environment-friendly, energy-saving and resource utilization system.

Description

technical field [0001] The invention belongs to the technical field of three wastes treatment and comprehensive utilization of environmental science and technology, and specifically relates to a mixed incineration system of phenol-containing waste water and gasification waste coke. Background technique [0002] As an industrial raw material or industrial gas, coal gas is widely used in chemical industry, building materials, steel and other industries. It uses water vapor to pass through the hot coal seam and react with high-temperature coke to produce gas. Its main components are carbon monoxide and hydrogen. And a small amount of components such as carbon dioxide, nitrogen and methane. In the process of gas production, it will be accompanied by the generation of pollutants such as hydrogen sulfide, tar, and phenolic wastewater. Among them, phenolic wastewater is a pollutant with complex components, which is mainly composed of phenols, sulfides, and cyanides. . Generally, ...

AI Technical Summary

Problems solved by technology

[0006] Bubbling fluidized bed method is mostly used in China. The disadvantage of gasification waste coke powder and phenolic wastewater is that the combustion conditions of the fuel are poor, and the ash content of the flue gas is relatively large, which will wear the heating surface of the tail boiler. More serious, but easy to operate
