您好,表4.5-1包围型集气设备废气收集效率分两类:一、污染物产生点(或生产设施)四周及上下有围挡设施,符合以下两种情况:1、仅保留1个操作工作面;2、仅保留物料进出通道,通道敞开面小于1个操作工位面。敞开面控制风速不小于0.5m/s,集气效率取值80%;敞开面控制风速在0.3-0.5m/s之间,集气效率取值60%;敞开面控制风速小于0.3m/s,集气效率取值0。二、污染物产生点(或生产设施)四周及上下有围挡设施,符合以下情况:通过软质垂帘四周围挡(偶有部分敞开),敞开面控制风速不小于0.5m/s,集气效率取值60%;敞开面控制风速在0.3-0.5m/s之间,集气效率取值40%;敞开面控制风速小于0.3m/s,集气效率取值0。感谢您的关注与支持! -来自广东省生态环境厅
