摘要

摘要: 通过对干化后典型有机废弃物生物水解固相残渣制备垃圾衍生燃料（RDF）颗粒的优化，研究了含水率及添加剂对RDF物理化学性质的影响。以果蔬、厨余和园林等典型有机废弃物生物水解后的固相残渣作为原料，经生物干化处理后，在不同含水率及不同比例添加剂条件下，对其制备RDF的抗压强度、膨胀率、成型率以及热值等指标进行对比研究，结果表明：当含水率为30%时，RDF颗粒成型率可达到99.47%；含水率为25%左右时，RDF颗粒的成型性能更好，抗压强度为8.28 MPa，膨胀率为40.41%；当含水率为10%时，低位热值为15.98 MJ/kg，满足固体回收燃料3级标准（EN 15359—2011《固体燃料的恢复和规范》）。在RDF制备中，添加5%的硅酸钠粉末可有效提升其成型效果，且灰分含量可控制在8.55%左右，能更好地满足RDF颗粒储存、运输以及燃烧的需求。

Abstract: The effect of moisture content (MC) and additives on the physicochemical properties of RDF was studied by optimizing the preparation of refuse derived fuel (RDF) from hydrolysis residues of organic waste after bio-drying. The experiment set different gradients of MC and additives using bio-drying treated hydrolysis residues from typical organic wastes such as fruits and vegetables, kitchen and garden. The comparison of the compressive strength, expansion rate, forming rate and calorific value showed that the formability of RDF with MC of 25% would be the best, whose compressive strength was 8.28 MPa and expansion rate was 40.41%; while the shaping rate with MC of 30% could be 99.47%. Therefore, the preparation of RDF in MC range of 25%~30% would be better. When MC was 10%, LHV could be 15.98 MJ/kg, which met the level 3 of the Solid Recovered Fuels-Specifications and Classes. Addition of 5% Na₂SiO₃ powder in the preparation of RDF could effectively improve its formability, and ash content could be controlled at about 8.55%, meeting the requirements of the storage, transportation and combustion of RDF.
