1.需要隔热的金属排烟管道。需要选用不燃保温材料，如矿棉、玻璃棉、岩棉、硅酸铝等。

1. Metal smoke exhaust pipes that require insulation. Non combustible insulation materials need to be selected, such as mineral wool, glass wool, rock wool, aluminum silicate, etc.

2.济南厨房排烟设备排烟管道外表面与木材等可燃构件的距离不应小于15，或排烟道外表面应采用厚度不小于10的保温材料进行保温。

2. The distance between the outer surface of the smoke exhaust duct of Jinan kitchen smoke exhaust equipment and combustible components such as wood should not be less than 15, or the outer surface of the smoke exhaust duct should be insulated with insulation materials with a thickness of not less than 10.

3.每层在上梁设置风管支架，支架处风管法兰加大(选用L50*5)，一侧法兰加长，用螺栓与固定在风管两侧梁上的槽钢连接。

3. Install air duct brackets on the upper beams of each floor, with enlarged flange (L50 * 5) at the bracket and extended flange on one side. Connect with bolts to the channel steel fixed on both sides of the air duct beams.

4.烟气出口的数据应由耐火性好的材料制成;排放口的朝向应根据建筑所在的条件进行确定，需要避免燃烧风险。

4. The data of the flue gas outlet should be made of materials with good fire resistance; The orientation of the discharge outlet should be determined based on the conditions of the building and to avoid the risk of combustion.

5.济南厨房排烟设备排烟管道穿过防烟墙时，管道与防烟墙之间的空间应用水泥砂浆等不燃材料填实;排烟管道与排烟风机的连接，排烟管道安装厂家建议选择法兰连接或不焚烧的软连接。

When the smoke exhaust pipe of Jinan kitchen smoke exhaust equipment passes through the smoke wall, the space between the pipe and the smoke wall should be filled with non combustible materials such as cement mortar; The connection between the smoke exhaust duct and the smoke exhaust fan is recommended by the smoke exhaust duct installation manufacturer to choose flange connection or non incineration soft connection.

6.排烟道采用镀锌钢板=1.5mm，法兰连接，接口密封数据选用防火8501填料，确保接口严密无漏油和异味。

6. The smoke exhaust duct is made of galvanized steel plate=1.5mm, connected by flanges, and the interface sealing data uses fire-resistant 8501 filler to ensure that the interface is tight and free of oil leakage and odor.

7.为了防止不同出烟口风压的相互影响，在每个出烟口增加了一个导流板。导流板的尺寸应根据风管的尺寸和每个厨房的排烟量来确定。  每个排烟口都应制造成朝向厨房的一定坡度，以尽可能防止油进入排烟道。

In order to prevent the mutual influence of wind pressure at different smoke outlets, a guide plate has been added to each smoke outlet. The size of the deflector should be determined based on the size of the air duct and the smoke exhaust volume of each kitchen. Each exhaust outlet should be manufactured with a certain slope towards the kitchen to prevent oil from entering the exhaust duct as much as possible.

8.风管的尺寸应根据设计的油烟排放量计算(但应尽可能增加)。为了便于今后油烟管道的清洗，风管的尺寸不得小于1000 * 400 mm。

8. The size of the air duct should be calculated based on the designed oil fume emissions (but should be increased as much as possible). In order to facilitate the cleaning of oil fume pipelines in the future, the size of the air duct shall not be less than 1000 * 400 mm.

9.为了风管设备的方便，风管制作的长度应根据楼层高度确定(使风管法兰高出楼层100-150mm)。

For the convenience of air duct equipment, the length of air duct production should be determined based on the height of the floor (so that the flange of the air duct is 100-150mm higher than the floor).

10、风管装置在风管关闭前，做漏光试验;屋顶排烟口百叶窗的面积是烟道截面积的1.5倍

10. Before closing the air duct, conduct a light leakage test on the air duct device; The area of the roof smoke exhaust louvers is 1.5 times the cross-sectional area of the flue
