Usually, the smoke hood we set in the kitchen is a partial smoke exhaust mode. In the process of design and installation, the first thing is to ensure the air speed of the smoke exhaust port. We can measure the total air volume required by the smoke exhaust hood according to the air speed of the smoke exhaust port. Then the overall air volume is used to calculate the cross section of the smoke exhaust pipe so as to determine the overall height of the kitchen smoke exhaust pipe.

　　我們在進行對排煙罩設計安裝時，要注意排煙罩所安裝的墻面需要有足夠好的構造以及材料。排煙的管道和出風口的墻面的開口處可以使用砌筑的帶洞的混領土快或者提前埋下鋼管注意留個洞，好使用空心磚來進行安裝，操作方式和普通的墻面一樣。假使墻面牢固的話，就需要用木板或者其他的材料進行加固。

　　When we design and install the smoke hood, we should pay attention to the good construction and material of the wall installed by the smoke hood. The smoke exhaust pipe and the wall opening of the air outlet can be used to build the mixed territory with holes quickly or bury the steel pipe ahead of time. It is better to use hollow bricks for installation. The operation mode is the same as the ordinary wall. If the walls are strong, they need to be reinforced with wood or other materials.

　　排煙罩的安裝應該從外墻穿內墻，在房間的外面排煙罩的出口處安裝一些防污染和避風的構件，并用豎向的煙道和油煙機連接，它的面積可以依據斷面所負擔的排氣量的決定，通常設置在燃氣灶的上方少65厘米的地方。當排煙罩發生了漏油或者漏風的情況，在設置管道時需要選擇防火的材料，在對管道進行安裝時要設置防火的閥門，要可以保證排煙罩在使用時發生火災防火閥門可以自己關閉。

　　Installation of smoke hood should go through the outer wall to the inner wall, install some anti-pollution and anti-wind components at the exit of the smoke hood outside the room, and connect it with a vertical flue and a lampblack machine. Its area can be determined by the amount of exhaust gas borne by the section, and it is usually located at least 65 centimeters above the gas stove. When the exhaust hood leaks oil or air, it is necessary to choose fire-proof materials when installing the pipeline. When installing the pipeline, it is necessary to set fire-proof valves, which can ensure that the fire-proof valves can be closed by themselves when the exhaust hood is in use.
