A method for disposing of kitchen waste based on a coal-fired power plant boiler and a pulverizing system, characterized in that the system for disposing of kitchen waste based on a coal-fired power plant boiler and a pulverizing system according to claim 1, comprising the following steps : 存储系统(1)输出的厨余垃圾在破碎筛分系统(2)中进行破碎，再对破碎后的厨余垃圾进行筛分，回收其中的金属成分，然后进入挤压分离系统(3)中进行固体与液体的粗分离，分离后的液体进入三相分离系统(4)中进行细分离，产生的液体从三相分离系统(4)排出后经液体储运系统(5)进入汽化及粉碎系统(6)中；The kitchen waste output from the storage system (1) is crushed in the crushing and screening system (2), and the crushed kitchen waste is then screened to recover the metal components, and then enter the extrusion separation system (3). Rough separation of solid and liquid is carried out, the separated liquid enters the three-phase separation system (4) for fine separation, and the generated liquid is discharged from the three-phase separation system (4) and then enters the vaporization and pulverization through the liquid storage and transportation system (5). In system (6); 将高温烟气接口(13)抽取的高温烟气引入汽化及粉碎系统(6)中，汽化及粉碎系统(6)输出的水蒸气、挥发分及固体粉末随烟气经燃烧器(11)进入煤粉锅炉(12)中进行焚烧处置，挤压分离系统(3)及三相分离系统(4)产生的固体物输送至电厂输煤系统(14)中与入炉煤进行掺配，随入炉煤一同进入制粉系统中磨制成粉，最后经一次风管道输送至煤粉锅炉(12)的高温炉膛进行焚烧，或输送至电厂磨煤机系统(15)中，与煤一同磨制成粉后经一次风管道输送至煤粉锅炉(12)的高温炉膛中进行焚烧处置。The high-temperature flue gas extracted from the high-temperature flue gas interface (13) is introduced into the vaporization and pulverization system (6), and the water vapor, volatile matter and solid powder output by the vaporization and pulverization system (6) enter with the flue gas through the burner (11) Incineration is carried out in the pulverized coal boiler (12), and the solids produced by the extrusion separation system (3) and the three-phase separation system (4) are transported to the coal conveying system (14) of the power plant for blending with the incoming coal, followed by The furnace coal enters the pulverizing system together and is ground into pulverized powder, and is finally transported to the high temperature furnace of the pulverized coal boiler (12) through the primary air pipeline for incineration, or transported to the power plant pulverizer system (15) to be ground together with the coal After being pulverized, the pulverized coal is transported to the high temperature furnace of the pulverized coal boiler (12) through the primary air pipeline for incineration.
