1.需要隔熱的金屬排煙管道。需要選用不燃保溫材料，如礦棉、玻璃棉、巖棉、硅酸鋁等。

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.濟(jì)南廚房排煙設(shè)備排煙管道外表面與木材等可燃構(gòu)件的距離不應(yīng)小于15，或排煙道外表面應(yīng)采用厚度不小于10的保溫材料進(jìn)行保溫。

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.每層在上梁設(shè)置風(fēng)管支架，支架處風(fēng)管法蘭加大(選用L50*5)，一側(cè)法蘭加長，用螺栓與固定在風(fēng)管兩側(cè)梁上的槽鋼連接。

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.

Smoke exhaust fan

4.煙氣出口的數(shù)據(jù)應(yīng)由耐火性好的材料制成;排放口的朝向應(yīng)根據(jù)建筑所在的條件進(jìn)行確定，需要避免燃燒風(fēng)險。

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.濟(jì)南廚房排煙設(shè)備排煙管道穿過防煙墻時，管道與防煙墻之間的空間應(yīng)用水泥砂漿等不燃材料填實;排煙管道與排煙風(fēng)機(jī)的連接，排煙管道安裝廠家建議選擇法蘭連接或不焚燒的軟連接。

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.排煙道采用鍍鋅鋼板=1.5mm，法蘭連接，接口密封數(shù)據(jù)選用防火8501填料，確保接口嚴(yán)密無漏油和異味。

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.為了防止不同出煙口風(fēng)壓的相互影響，在每個出煙口增加了一個導(dǎo)流板。導(dǎo)流板的尺寸應(yīng)根據(jù)風(fēng)管的尺寸和每個廚房的排煙量來確定。  每個排煙口都應(yīng)制造成朝向廚房的一定坡度，以盡可能防止油進(jìn)入排煙道。

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.風(fēng)管的尺寸應(yīng)根據(jù)設(shè)計的油煙排放量計算(但應(yīng)盡可能增加)。為了便于今后油煙管道的清洗，風(fēng)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.為了風(fēng)管設(shè)備的方便，風(fēng)管制作的長度應(yīng)根據(jù)樓層高度確定(使風(fēng)管法蘭高出樓層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、風(fēng)管裝置在風(fēng)管關(guān)閉前，做漏光試驗;屋頂排煙口百葉窗的面積是煙道截面積的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
