某集成电路工厂废水站通风系统设计

Design of Ventilation System for a Wastewater Station of an Integrated Circuit Factory

文中以某集成电路工厂废水站通风系统设计为例,分析污染物在操作车间的分布情况后,从通风形式选择、风量计算、通风机选型以及气流组织设计等方面论述了该类型建筑通风系统设计,对产生大量污染物且排风条件较不利的污泥脱水机房通风系统的通风效果进行了模拟论证及评价。结果表明,气流组织合理的情况下,标准要求的换气次数12次/h可使室内空气品质保持良好,风口布置均匀的低污染物浓度区适合设置人员操作区。

The ventilation system design of a wastewater station in an integrated circuit factory is as an example.After analyzing the distribution of pollutants in the operating workshop,the ventilation system design of this type of building is discussed from the aspects of ventilation form se-lection,air volume calculation,fan selection,and airflow organization design.The ventilation effect of the sludge dewatering room ventilation system,which generates a large amount of pollutants and has unfavorable exhaust conditions,was simulated and evaluated.The results showed that under reasonable airflow organization,the standard requirement of ventilation rate as 12 times per hour can maintain good indoor air quali-ty,and a low pollutant concentration area with uniform air outlet layout is suitable for setting up a personnel operation area.
