摘要
根据某垃圾焚烧处理中心建筑结构,确定通风方案布局,设计了一种新型除臭通风系统.利用CFD仿真分析的方法,模拟该方案的通风效果,结果表明:料坑与平台区域负压分布均匀,梯度变化明显,整体处于-32^-39Pa的微负压环境下,料坑内臭气浓度分布整体处于0.17mol/m3以下,通风效果较好,满足设计要求.
According to the building structure of a waste incineration plant,the ventilation scheme layout is determined through literature and engineering experience.A new type of deodorizing ventilation system is designed based on the empirical formula theory.By using the method of CFD simulation,simulation of ventilation ventilation scheme,and the simulation shows that the pit platform area negative pressure distribution uniformity,obvious gradient change,overall in the -32 Pa to -39 Pa micro negative pressure condition,the odor concentration distribution of material in the pit in the overall below 0.17 mol/m 3,and the ventilation effect is good,which meets the design requirements.
