1.需要(yao)(yao)隔熱的金屬排煙管道(dao)。需要(yao)(yao)選(xuan)用不(bu)燃保溫材料，如礦棉(mian)(mian)、玻璃(li)棉(mian)(mian)、巖棉(mian)(mian)、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.濟南(nan)廚(chu)房排煙設備排煙管道(dao)(dao)外表(biao)面(mian)與木材(cai)等可燃構件的距(ju)離(li)不(bu)應小于15，或排煙道(dao)(dao)外表(biao)面(mian)應采用厚(hou)度不(bu)小于10的保溫材(cai)料進行保溫。

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(she)置風(feng)管支架，支架處風(feng)管法蘭(lan)加大(選用L50*5)，一(yi)側法蘭(lan)加長，用螺栓與固定在風(feng)管兩側梁上的槽鋼連接。

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.

4.煙氣出口的數據應(ying)由(you)耐火(huo)性好的材料(liao)制成;排放口的朝向應(ying)根據建筑所在的條(tiao)件進行(xing)確(que)定，需要避免(mian)燃(ran)燒風險。

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.濟南廚房排煙(yan)(yan)設(she)備(bei)排煙(yan)(yan)管道(dao)穿過(guo)防煙(yan)(yan)墻時(shi)，管道(dao)與(yu)防煙(yan)(yan)墻之(zhi)間的(de)(de)空間應(ying)用水泥砂漿等不燃材(cai)料填實;排煙(yan)(yan)管道(dao)與(yu)排煙(yan)(yan)風機(ji)的(de)(de)連(lian)接，排煙(yan)(yan)管道(dao)安(an)裝廠家建議選(xuan)擇(ze)法蘭連(lian)接或不焚燒的(de)(de)軟連(lian)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(dao)采(cai)用鍍鋅鋼板=1.5mm，法蘭(lan)連接(jie)，接(jie)口密(mi)封數據選用防(fang)火8501填料(liao)，確保接(jie)口嚴密(mi)無漏(lou)油和異(yi)味(wei)。

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(yan)(yan)口(kou)風壓(ya)的相互影響，在每(mei)(mei)個(ge)出煙(yan)(yan)口(kou)增(zeng)加了一個(ge)導流(liu)板。導流(liu)板的尺寸應根(gen)據風管的尺寸和每(mei)(mei)個(ge)廚房(fang)的排(pai)煙(yan)(yan)量來確定(ding)。  每(mei)(mei)個(ge)排(pai)煙(yan)(yan)口(kou)都應制(zhi)造成朝向廚房(fang)的一定(ding)坡度(du)，以盡可能防止油(you)進入排(pai)煙(yan)(yan)道(dao)。

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.風管(guan)(guan)的(de)尺寸應根據設(she)計的(de)油(you)煙排放量(liang)計算(但(dan)應盡(jin)可能增加)。為了便于(yu)今后油(you)煙管(guan)(guan)道的(de)清洗，風管(guan)(guan)的(de)尺寸不得(de)小于(yu)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(wei)了風(feng)管(guan)設備的方便，風(feng)管(guan)制作的長度(du)應根(gen)據樓層(ceng)高(gao)度(du)確定(使風(feng)管(guan)法(fa)蘭高(gao)出樓層(ceng)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(feng)管裝置在風(feng)管關閉前，做漏(lou)光試驗(yan);屋頂排煙(yan)口百葉窗的(de)面積是煙(yan)道截面積的(de)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
