Grilling restaurants are a major contributor to airborne particulate matter (PM) in metropolitan areas. In this study, the removal of PM during the grilling of pork belly using an orifice scrubber, which is a form of gas-induced spray scrubber, was assessed. During grilling, the particle mass concentration was the highest for 1.0 < PM ≤ 2.5 μm (55.5% of total PM emissions), followed by 0.5 < PM ≤ 1.0 (27.1%), PM ≤ 0.5 (10.7%), and PM > 2.5 μm (7.0%). The PM removal efficiency of the orifice scrubber at a gas flow of 4.5 m min was > 99.7% for PM ≥ 2.5 μm, 89.4% for 1.0 < PM ≤ 2.5 μm, 62.1% for 0.5 < PM ≤ 1.0, and 36.5% for PM ≤ 0.5 μm. Although further research is necessary to optimize its use, the orifice scrubber offers a user-friendly technology for the control of PM in small grilling restaurants because of its simple design, uncomplicated operation, and satisfactory PM removal performance.
烧烤餐厅是大都市空气中颗粒物（PM）的主要来源之一。在这项研究中，评估了一种孔口洗涤器（一种气体诱导喷雾洗涤器）在烤五花肉过程中去除 PM 的效果。在烧烤过程中，1.0<PM≤2.5μm（总 PM 排放的 55.5%）的颗粒物质量浓度最高，其次是 0.5<PM≤1.0（27.1%）、PM≤0.5（10.7%）和 PM>2.5μm（7.0%）。在气体流量为 4.5 m min 的情况下，孔口洗涤器对 PM≥2.5μm 的去除效率>99.7%，对 1.0<PM≤2.5μm 的去除效率为 89.4%，对 0.5<PM≤1.0 的去除效率为 62.1%，对 PM≤0.5μm 的去除效率为 36.5%。尽管需要进一步的研究来优化其使用，但由于其设计简单、操作不复杂且 PM 去除性能令人满意，孔口洗涤器为小型烧烤餐厅的 PM 控制提供了一种用户友好的技术。
