装修垃圾资源化处理的跨领域碳减排作用分析

Analysis of Cross-domain Carbon Emission Reduction Effect of Decoration Waste Treatment for Resource Utilization

本文介绍了我国建筑装修垃圾处理的现状,指出在“骨料资源化”基础上,装修垃圾预处理分选出的高热值组分如何实现“厂内资源化”,将是未来装修垃圾资源化率进一步提高的关键环节。本文重点介绍了以“硬质物料粗破/软质物料链板上料+磁选+筛分+筛下灰土外运+筛上物摩擦清洗细碎+混料+RDF制备”工艺技术路线为指导,开展的带料中试实验研究,其主产品性能优异,可作为水泥行业替代燃料的优质采购对象。建立替代原燃材料供应支撑体系,加大清洁能源使用比例,是联系装修垃圾处理行业与水泥行业的绿色纽带,将成为跨领域协同降碳的示范性应用体系。

This paper introduced the current situation of construction and decoration waste treatment in China.It pointed out that on the basis of"aggregate recycling",how to realize"in-plant recycling"of the high calorific value components sorted out through the pretreatment of decoration waste would be the key link to further improve the recycling rate of decoration waste in the future.This paper is focused on introducing the pilot test research of belt materials carried out under the guidance of the technological route of"coarse breaking of hard materials/chain plate feeding of soft materials+magnetic separation+screening+outward transportation of ash and dust under the screen+friction cleaning and fine crushing of materials on the screen+mixing+RDF preparation".The main product has excellent performance and can be used as a high-quality procurement target for the demand of alternative fuels in the cement industry.Establishing a support system for the supply of alternative raw materials and fuels and increasing the proportion of clean energy consumption are green links between the decoration waste treatment industry and the cement industry,and such a system will become a demonstration application system for cross-domain synergistic carbon reduction.
