When building a house, the kitchen is like this. It must be designed with a kitchen to exhaust the smoke. Otherwise, it is usually impossible to exhaust the smoke in the later stage, which will not only cause air pollution in the home, but also harm the health. But many people don't understand the design of kitchen exhaust, so it can't be designed normally. So, next, let's take a look at the principle and design points of kitchen exhaust system. In addition, in daily use, the kitchen exhaust pipe must be cleaned to ensure normal use.

濟南廚房排煙系統主要由集煙罩、排煙管、油煙凈化器、排煙風機(含消聲器)、廚房送風裝置等組成。

Jinan kitchen smoke exhaust system is mainly composed of smoke collection hood, smoke exhaust pipe, fume purifier, smoke exhaust fan (including muffler), kitchen air supply device, etc.

由于廚房所在的建筑物的格局與廚房在建筑物的方位不同，有條件的廚房應由建筑物的連接空調系統進行有序的出風。但在大多數情況下，建筑物沒有廚房空氣供應。許多帶有餐廳、廚房等的建筑物只有一個聯合供暖系統，而沒有一個聯合空調系統。當廚房處于運行狀態時，將排風系統投入運行，廚房處于負壓狀態，新風來源包括室外新風滲入和大量餐廳空氣進入廚房。

Because the layout of the building where the kitchen is located is different from the orientation of the kitchen in the building, the conditional kitchen should be orderly ventilated by the air conditioning system connected to the building. But in most cases, the building does not have a kitchen air supply. Many buildings with restaurants, kitchens, etc. have only one combined heating system, but not one combined air conditioning system. When the kitchen is in operation state, put the exhaust system into operation, and the kitchen is in negative pressure state. The fresh air source includes outdoor fresh air infiltration and a large number of restaurant air entering the kitchen.

許多人知道有煙道，但不知道有二次煙道。主煙道貫穿整個建筑，而副煙道是獨立的。它與主煙道之間有一個帶孔的隔墻，上下兩層都是密封的。而家里的油煙——是先到二級煙道再到二級煙道，二級煙道有緩沖作用，油煙通過隔板上的孔進入主煙道，這樣做是為了保證不讓油煙分開，避免冒煙。

Many people know there is a flue, but they don't know there is a secondary flue. The main flue runs through the whole building, while the auxiliary flue is independent. There is a partition wall with holes between it and the main flue, and the upper and lower layers are sealed. And the oil smoke in the home is first to the secondary flue and then to the secondary flue. The secondary flue has a buffering effect. The oil smoke enters the main flue through the hole on the partition plate, so as to ensure that the oil smoke is not separated and avoid smoke.
