Slag waste treatment system for garbage gasifier

Abstract

The invention discloses a slag waste treatment system for a garbage gasifier. The slag waste treatment system comprises a gasifier and a slag crushing and extruding device; the slag crushing and extruding device comprises a plurality of transmission shafts arranged side by side and is communicated under the gasifier; a plurality of impeller blades are arranged on each of the transmission shafts in an array manner; the impeller blades on the adjacent transmission shafts are arranged in a staggered manner; a power device is connected with the transmission shafts and can drive the transmission shafts to rotate. In the slag waste treatment system disclosed by the invention, slag formed by burning is supported above the transmission shafts and the impeller blades; the transmission shafts drive the impeller blades to rotate together under the action of the power device; the impeller blades perform crushing treatment on the agglomerated slag in the rotating process; meanwhile, the crushed slag is extruded under the impeller blades through gaps to be collected and transported.

Description

technical field [0001] The present application belongs to the technical field of environmental protection, and in particular relates to a waste gasifier ash and slag waste treatment system. Background technique [0002] Gasification of waste and combustible waste is a thermochemical process that converts waste fuel into combustible gas. In this process, water vapor, free oxygen or combined oxygen undergo a thermochemical reaction with the carbon in the fuel to generate a combustible gas. [0003] The slag produced by the existing gasifier is directly collected and transported, but it is difficult to clean up and discharge due to the high temperature of the ash after combustion or the formation of lumps. [0004] In addition, the ash and slag produced by the gasifier must be continuously discharged to the outside of the furnace to avoid accumulation and blockage, so as to ensure continuous and normal operation. Clean up and drain. [0005] In view of this, it is necessary ...

Problems solved by technology

[0003] The slag produced by the existing gasifier is directly collected and transported, but it is difficult to clean and discharge because of the high temperature of the ash and slag after combustion.

[0004] In addition, the ash and slag produced by the gasification furnace must be continuously discharged outside the furnace to avoid accumulation and blockage, so as to ensure continuous normal operation. Clean up and discharge
