在济南，烧烤是街头巷尾的烟火担当，无论是热闹的烧烤店，还是熙攘的美食广场烧烤区，食客们大快朵颐之时，大量油烟也随之产生。此时，通风管道就如同一位默默守护的卫士，肩负着净化空气、维持舒适环境的重任。不过，烧烤区独特的排烟需求，让通风管道的设计与安装有着特殊考量。

　　In Jinan, barbecue is the source of fireworks on the streets and alleys. Whether it's lively barbecue restaurants or bustling food court barbecue areas, as diners feast on their food, a large amount of oil fumes are also produced. At this moment, the ventilation duct is like a silent guardian, shouldering the responsibility of purifying the air and maintaining a comfortable environment. However, the unique smoke exhaust requirements of the barbecue area require special considerations for the design and installation of ventilation ducts.

　　高效捕烟，精准定位源头

　　Efficient smoke capture and precise source positioning

　　烧烤区的油烟产生集中且量大，首要任务是在源头精准捕捉。排烟罩的设计至关重要，需根据烧烤炉具的布局、数量与规格量身定制。常见的有下吸式和上吸式排烟罩。下吸式排烟罩安装在烧烤炉下方，能第一时间捕获从烤架缝隙中逸出的油烟，对于桌面式烧烤炉十分适用，如一些日式烤肉店，食客围坐，下吸式排烟罩可确保每个座位周边的油烟都

　　The production of oil fumes in the barbecue area is concentrated and large, and the primary task is to accurately capture them at the source. The design of the exhaust hood is crucial and needs to be customized according to the layout, quantity, and specifications of the barbecue stove. Common types include downward suction and upward suction smoke exhaust hoods. The downward suction smoke exhaust hood is installed under the barbecue grill, which can capture the oil smoke escaping from the gaps of the grill in a timely manner. It is very suitable for desktop barbecue grills, such as some Japanese style barbecue restaurants where diners sit around. The downward suction smoke exhaust hood can ensure that the oil smoke around each seat is collected

　　被及时吸，避免油烟在食客间弥漫。上吸式排烟罩则安装在烤炉上方，适用于大型烧烤店的集中式烤炉，其面积大、吸力强，可将烤炉上方一定范围内的油烟尽收囊中。例如，济南一些传统烧烤老店，烤串师傅在一排长长的烤炉前忙碌，上方大面积的上吸式排烟罩，能高效收集烤制过程中产生的滚滚油烟，确保店内空气保持相对清新。

　　Be promptly sucked in to avoid the spread of oil fumes among diners. The upward suction exhaust hood is installed above the oven and is suitable for centralized ovens in large barbecue restaurants. It has a large area and strong suction power, and can collect the oil fumes within a certain range above the oven. For example, in some traditional barbecue restaurants in Jinan, skewers chefs are busy in front of a long row of ovens. The large upward suction smoke hood above can efficiently collect the rolling oil fumes generated during the baking process, ensuring that the air inside the restaurant remains relatively fresh.

　　强大动力，保障油烟速排

　　Powerful power ensures fast exhaust of oil fumes

　　烧烤产生的油烟量大且浓度高，需要通风管道具备强大的排风动力。风机作为通风系统的 “心脏”，其选型极为关键。要依据烧烤区的空间大小、炉具数量以及预估的油烟产生量，计算出合适的排风量，从而选择匹配功率的风机。在小型烧烤店，一台功率适中的轴流风机或许就能满足需求，它结构简单、安装方便，能以较高的风速将油烟快速排出室外。而大型美食广场的烧烤区，由于涉及多个摊位，油烟产生总量大，就需选用离心风机，其风压高、风量稳定，即便通风管道较长、弯头较多，也能确保油烟顺利排出，避免在管道内积聚。比如某大型商场的美食广场，多个烧烤摊位集中，离心风机通过合理布局的通风管道，将各个摊位的油烟统一收集并高效排出，保障整个美食广场的空气质量。

　　Barbecue produces a large amount and high concentration of oil fumes, requiring ventilation ducts to have strong exhaust power. As the "heart" of a ventilation system, the selection of fans is extremely crucial. The appropriate exhaust volume should be calculated based on the size of the barbecue area, the number of stoves, and the estimated amount of oil fume generated, in order to select a fan with matching power. In a small barbecue restaurant, a moderately powered axial fan may be sufficient to meet the demand. It has a simple structure, easy installation, and can quickly exhaust oil fumes outdoors with high wind speed. In the barbecue area of a large food court, due to the involvement of multiple stalls, the total amount of oil fume generated is large. Therefore, centrifugal fans need to be used, which have high air pressure and stable air volume. Even if the ventilation ducts are long and have many bends, they can ensure the smooth discharge of oil fume and avoid accumulation in the ducts. For example, in the food court of a large shopping mall, multiple barbecue stalls are concentrated, and centrifugal fans collect and efficiently exhaust the fumes from each stall through a properly arranged ventilation duct, ensuring the air quality of the entire food court.

　　材质精选，应对高温油脂

　　Selected materials to cope with high temperature grease

　　烧烤过程中，油烟温度较高，且富含油脂，这对通风管道的材质提出了严格要求。首选不锈钢材质，其具有出色的耐高温性能，能承受烧烤油烟的高温冲击而不变形、不损坏。同时，不锈钢表面光滑，油脂不易附着，方便后期清洗维护。在一些对美观度有要求的烧烤场所，还可选用经过特殊处理的彩色不锈钢管道，既满足排烟功能，又能与店内装修风格相融合。此外，对于靠近烧烤炉具的部分管道，可采用双层结构，内层耐高温耐腐蚀，外层起到隔热作用，防止烫伤周边人员，进一步提升安全性。

　　During the barbecue process, the temperature of the cooking fumes is high and rich in oil, which imposes strict requirements on the material of the ventilation ducts. The preferred material is stainless steel, which has excellent high temperature resistance and can withstand the high temperature impact of barbecue fumes without deformation or damage. At the same time, the surface of stainless steel is smooth and grease is not easy to adhere, making it convenient for later cleaning and maintenance. In some barbecue venues that require aesthetic appeal, specially treated colored stainless steel pipes can also be used to meet the smoke exhaust function and blend with the interior decoration style. In addition, for the pipes near the barbecue stove, a double-layer structure can be used, with the inner layer being heat-resistant and corrosion-resistant, and the outer layer serving as insulation to prevent burns to surrounding personnel and further enhance safety.

　　定期维护，保持系统 “健康”

　　Regular maintenance to keep the system 'healthy'

　　烧烤区通风管道的维护不可或缺。由于油烟中油脂含量高，长时间使用后管道内壁会附着厚厚的油垢，不仅影响排烟效率，还存在火灾隐患。因此，需制定定期清洗计划。可采用专业的管道清洗设备，如高压水枪配合专用的除油清洗剂，将管道内的油垢彻底清除。同时，要定期检查风机的运行状况，查看叶轮是否有磨损、电机是否运转正常，及时更换损坏部件，确保风机始终处于良好的工作状态。此外，对通风管道的各个连接部位进行检查，防止因油烟侵蚀导致接口松动、漏风，影响排烟效果。

　　The maintenance of ventilation ducts in the barbecue area is indispensable. Due to the high oil content in cooking fumes, thick oil stains will adhere to the inner wall of the pipeline after prolonged use, which not only affects smoke exhaust efficiency but also poses a fire hazard. Therefore, a regular cleaning plan needs to be developed. Professional pipeline cleaning equipment can be used, such as high-pressure water guns combined with specialized oil removal cleaning agents, to thoroughly remove oil stains from the pipeline. At the same time, it is necessary to regularly check the operation status of the fan, check whether the impeller is worn, whether the motor is running normally, replace damaged parts in a timely manner, and ensure that the fan is always in good working condition. In addition, check the various connection parts of the ventilation ducts to prevent loose interfaces and air leaks caused by oil fume erosion, which may affect the smoke exhaust effect.
