The horizontal section of the kitchen smoke exhaust pipe should not be too long. Generally, the horizontal distance should not exceed 15m, and there should be a small slope. A movable joint is set at the horizontal end to facilitate the cleaning of oil dirt.

廚房排煙管道的排風速度按規范不得低于10m/s，以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。

The exhaust speed of the kitchen smoke exhaust pipe shall not be less than 10m / s according to the specification, so as to prevent the oil from adhering to the flue due to the low wind speed. The branch pipe connected to the exhaust hood shall be equipped with an air volume regulating valve.

廚房排煙系統的主排煙管道通風面積不能太小，風速不能太大。濟南廚房排煙依照工程經驗，排煙主管道內風速不能超過15m/s。否則在運行一個時期以后（如一年以后）很容易造成排煙系統不通暢。

The ventilation area of the main smoke exhaust pipe of the kitchen smoke exhaust system shall not be too small and the wind speed shall not be too large. According to the engineering experience of kitchen smoke exhaust in Jinan, the wind speed in the main smoke exhaust pipe shall not exceed 15m / s. Otherwise, after a period of operation (such as one year), it is easy to cause the smoke exhaust system to be blocked.

廚房排煙]如何設計廚房排煙管

Kitchen smoke exhaust] how to design kitchen smoke exhaust pipe

一根據風機的進出口徑定制同截面的排煙管，方可保證設備的處理效果及設備的經濟運行。

First, customize the smoke exhaust pipe with the same section according to the inlet and outlet diameter of the fan, so as to ensure the treatment effect of the equipment and the economic operation of the equipment.

二廚房蒸汽散熱管路與廚房油煙機排煙管分別安裝。

Second, the steam heat dissipation pipeline of the kitchen and the smoke exhaust pipe of the kitchen range hood shall be installed respectively.

三廚房排煙管彎頭的額曲率半徑：因為彎頭的曲率半徑小將增加風管阻力，濟南廚房排煙故一般選擇彎頭曲率半徑為1.5D較為合適，在設置彎頭處應預先留下彎頭的擺放空間及安裝操作空間。

III. radius of curvature of the elbow of kitchen smoke exhaust pipe: because the radius of curvature of the elbow is small, it will increase the air duct resistance. For smoke exhaust in Jinan kitchen, it is generally appropriate to select the radius of curvature of the elbow as 1.5D. The placement space and installation operation space of the elbow shall be reserved in advance at the place where the elbow is set.

四安裝預留空間：油煙凈化器的安裝位置在電控箱一側1.5米左右的空間作為油煙凈化器維修維護的空間。濟南廚房排煙

IV. reserved space for installation: the installation position of the oil fume purifier is about 1.5m on one side of the electric cabinet as the space for maintenance of the oil fume purifier. Jinan kitchen smoke exhaust
