Embodiment 1
[0070] A disposal system for combustible industrial solid waste,
[0071] See figure 1 , the system includes a circulating fluidized bed boiler, a crushing and conveying device, a feeding device in front of the furnace, a bed material conveying device, a secondary SNCR denitrification device and a flue gas treatment subsystem. The flue gas treatment subsystem is used for flue gas deacidification, Heavy metal removal, dioxin removal and dust removal;
[0072] The circulating fluidized bed boiler includes a circulating fluidized bed boiler body, a primary fan 11, a secondary fan 12, an induced draft fan 13, a feeding fan 14 and a slag cooler 15, and the circulating fluidized bed boiler body includes a furnace 16, a cloth Air plate 161 and air chamber, two cyclone separators 10, "J" valve feeder 17, tail shaft flue 18, steam drum.
[0073] The flue gas outlet at the top of the furnace 16 of the circulating fluidized bed boiler is respectively connected to the upper flue gas inl...
Embodiment 2
[0090] Based on the above system, the present invention also includes a method for disposing of combustible industrial solid waste,
[0091] See image 3 , including the following steps:
[0092] Step (1): crushing and conveying process
[0093] The combustible industrial solid waste in the industrial solid waste storage warehouse, the combustible industrial solid waste has an ash content of 2% to 9%, and is transported to the primary shredder 31 through the chain conveyor 30 for crushing and primary crushing. The iron remover 32 removes iron to obtain first-grade solid waste particles, and the particle size of the first-grade solid waste particles is ≤150*200mm,
[0094] The first-level solid waste particles are transported to the second-level crusher 33 by the belt conveyor 1 for crushing and the second-level iron remover 34 to remove iron to obtain the second-level solid waste particles, and the particle size of the second-level solid waste particles is ≤80*80mm,
