1. The ventilation area of the main exhaust pipe is not enough.

根據(jù)工程經(jīng)驗(yàn)，主管道風(fēng)速不能超過(guò) 15m/s，否則在運(yùn)行一段時(shí)間后很容易使排煙系統(tǒng)通暢。在油煙凈化器的運(yùn)行實(shí)踐中，大部分情況是由于排氣管通風(fēng)面積不足所致，管道內(nèi)氣體流量在 15m/ s 以上。

According to the project experience, the wind speed of the main pipe shall not exceed 15m/s, otherwise it is easy to make the smoke exhaust system smooth after a period of operation. In the operation practice of the oil fume purifier, most of the cases are caused by insufficient ventilation area of the exhaust pipe, and the gas flow in the pipe is more than 15m/s.

2.管道的橫截面面積變小

2. The cross-sectional area of the pipe becomes smaller

由于需要通過(guò)建筑橫梁，管道的通風(fēng)截面面積變小，截面上的阻力加大，導(dǎo)致氣流不順暢。

Because of the need to pass through the building beam, the ventilation cross section area of the pipe becomes smaller, and the resistance on the cross section increases, resulting in the air flow is not smooth.

3.使用排水管后集料的積聚

3. Aggregates accumulation after using drain pipe

當(dāng)排煙管通過(guò)建筑物橫梁或避開其他設(shè)備管道時(shí)，排煙管的某一部分將低于排煙管的整體水平。使用一段時(shí)間后，由于油水混合物將積聚在排氣管的下部，排煙將受到直接影響。

When the smoke exhaust pipe passes through the building beam or avoids other equipment pipes, a part of the smoke exhaust pipe will be lower than the overall level of the smoke exhaust pipe. After using for a period of time, as the oil-water mixture will accumulate at the lower part of the exhaust pipe, the smoke exhaust will be directly affected.

4.低排煙不平坦

4. Uneven low smoke exhaust

不同樓層的廚房煙氣通過(guò)同一主管道排出，廚房出口附近的廚房排煙效果較好，但下樓廚房的排煙不順暢。

The smoke from kitchens on different floors is discharged through the same main pipe. The kitchen near the kitchen exit has a good smoke exhaust effect, but the smoke exhaust of the kitchen downstairs is not smooth.

5.建議安裝排煙風(fēng)扇

5. It is recommended to install smoke exhaust fan

對(duì)于大排煙的廚房，還建議安裝排煙風(fēng)扇。有三種排煙風(fēng)扇：軸流風(fēng)扇、空氣底盤和離心風(fēng)扇。

For kitchens with large smoke exhaust, it is also recommended to install smoke exhaust fans. There are three types of smoke exhaust fans: axial fan, air chassis and centrifugal fan.

一般情況來(lái)講，通風(fēng)管道在安裝過(guò)程當(dāng)中提前設(shè)計(jì)好當(dāng)前廚房的規(guī)劃，從而減少通風(fēng)管道出現(xiàn)的排煙不正常狀況

Generally speaking, the current kitchen plan shall be designed in advance during the installation of the ventilation duct, so as to reduce abnormal smoke exhaust of the ventilation duct
