摘要：

Industrial kiln co-processing solid waste technology is an effective way to scientifically dispose of solid waste. The high temperature environment of industrial kilns is conducive to the thorough transformation and decomposition of solid waste, and effectively controls secondary pollution such as dioxins and heavy metals. At the same time, it can save the investment and operating costs of special solid waste disposal facilities and replace part of the fossil fuels or production raw materials needed for industrial production. In this paper, the co-processing technology of solid waste in industrial kilns, such as cement kilns, steel smelting kilns, coal-fired boilers in power plants and coal-water slurry gasifiers, are introduced. The technical research and engineering application status of co-processing solid waste in industrial kilns is reviewed. Combining the properties of solid waste and the characteristics of industrial kilns in various industries, the applicability of solid waste is analyzed. Comparing the common non-heat treatment technology of solid waste and heat treatment technology of solid waste, it is pointed out that the industrial kiln co-processing solid waste technology had the advantages of high potential of solid waste elimination, high level of resource utilization, good environmental benefits and no neighbor avoidance effect. Finally, the future development of the field of solid waste co-processing is prospected. The industry standards, technical specifications, laws and regulations for the co-processing of solid waste in cement kilns are becoming mature, while there is still more technology optimization space and development potential in the co-processing of solid waste technology in steel smelting kilns, coal-fired boilers in power plants and coal-water slurry gasifiers. © 2022, Chemical Industry Press Co., Ltd.
