摘要
隧道通风需风量的确定是取CO浓度指标和烟雾指标计算出来的较大者作为需风量。如果是烟雾浓度指标的需风量大于CO指标需风量,则静电除尘装置的使用可以降低隧道内的需风量,从而提高了运行的经济性。在不同的坡度和车速下,机动车的CO和烟雾的排放特性会发生变化。研究了在不同的坡度和车速下,静电除尘装置基本使用条件的确定。研究成果可用于隧道通风设计与研究中。
When determining air demand for tunnel ventilation, the air demand is taken from the bigger one between ealeulation of CO concentration index and smog concentration index. If the air demand from smog concentration index is higher than that of the CO concentration index, then the application of eleetrostatie dedusting unit may reduce the air demand inside tunnel, so to improve economy of operation. The emission property of CO and smog from motor vehicles may vary under different slopes and velocities. This paper studies determination of basic application conditions of electrostatic dedusting unit under different slope and driving speed. The achievement of study may be applied in tunnel ventilation design and research.
