摘要

阴燃处置技术作为新兴的高湿固体废物处理手段，在处置高湿低热值污泥方面展现出独特优势，然而其自持传播过程易受物料特性与运行参数影响，存在反应强度衰减导致的传播失稳风险。故以含水率大于65%的高湿污泥为处置对象，系统考察石英砂与污泥掺混质量比（2:1～5:1）、空气达西流速（5～8 cm/s）对生物质调质原料污泥的阴燃传播特性影响，探究阴燃完全传播的生物质调质比例边界。结果表明：在固定达西流速为5 cm/s条件下，石英砂与污泥掺混比从2:1增加到5:1时，维持阴燃完全传播的临界生物质调质比例从4%呈线性增长至10%，阴燃系统临界单位热值稳定于0.339 MJ/kg；当石英砂与污泥掺混比例固定为3:1时，达西流速由5 cm/s提升至8 cm/s，临界生物质调质比例从6%也基本呈现线性递减至2%，对应临界单位热值由0.339 MJ/kg线性降至0.172 MJ/kg；阴燃处置后物料存在塌陷特征，且当生物质调质比例超过临界值后，其含量变化对顶部塌陷高度无显著影响。该研究结果可为解决高湿污泥高效阴燃处置提供参考。

Abstract

As an emerging high-moisture solid waste treatment method

smoldering disposal technology shows unique advantages in the disposal of high-moisture and low-calorific sludge. However

its self-sustaining propagation process is easily affected by material characteristics and operating parameters

and there is a risk of propagation instability caused by the attenuation of reaction intensity. Taking high-moisture sludge(moisture content 65%) as the disposal object

this study systematically investigates the effects of the mixing ratio of quartz sand to sludge(2:1～5:1) and air Darcy velocities(5～8 cm/s) on smoldering propagation under biomass conditioning

and explores the boundary of biomass conditioning ratio for complete smoldering propagation. The results show that under the condition of a fixed Darcy flow rate of 5 cm/s

the critical biomass conditioning ratio linearly increases from 4% to 10% and the critical unit calorific value of the smoldering system remains stable at approximately 0.339 MJ/kg when the sand-sludge mixing ratio is increased from 2:1 to 5:1. When the sand-sludge mixing ratio is fixed at 3:1

the critical biomass conditioning ratio linearly decreases from 6% to 2% when the air Darcy velocity increases from 5 cm/s to 8 cm/s

corresponding to a linear decrease in critical unit calorific value from 0.339 MJ/kg to 0.172 MJ/kg. The material exhibits collapse characteristics after smoldering disposal

and the biomass conditioning ratio has no significant effect on the top collapse height when it exceeds the critical value. These results can provide reliable scientific references for solving the efficient smoldering disposal of high-moisture sludge.
