Title:
SOLID WASTE SYNERGISTIC SINTERING AND PELLETIZING DISPOSAL PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/218044
Kind Code:
A1
Abstract:
Disclosed in the present invention is a solid waste synergistic sintering and pelletizing disposal process. The disposal process comprises: sieving solid waste residue obtained by means of subjecting multi-source solid waste to incineration and/or a pyrolysis treatment, then mixing and conveying coarse-particle-size solid waste residue and sintering raw materials to a sintering procedure, and mixing and conveying fine-particle-size solid waste residue and pelletizing raw materials to a pelletizing procedure. The solid waste residue can replace part of the fuel, such that the production cost is lowered; moreover, by selectively adding the sintering procedure or the pelletizing procedure, situations where the sintering quality is lowered due to the direct mixing of fine-particle-size solid waste residue into the sintering raw materials, and where the coarse-particle solid waste residue entering the pelletizing raw materials is not beneficial to pelletizing can also be avoided. In addition, a heat source generated during the incineration procedure and/or the pyrolysis procedure of the solid waste can also enter a high-water-content ore pretreatment system as a heat source. In order to provide a new way for realizing full-process disposal of various solid wastes, the impact of solid waste on the environment and the risk of secondary pollution are thoroughly eliminated while ensuring the quality of a sinter ore and a pellet ore.
