The planning and installation of kitchen smoke exhaust pipe is unreasonable, which often leads to the unsmooth smoke exhaust in the kitchen and directly affects the use of fume purifier. What causes the unreasonable design of kitchen smoke exhaust pipe? The kitchen smoke engineering company will explain it to you below!

　　主要原因如下:

　　The main reasons are as follows:

　　主排氣管通風面積不好

　　Poor ventilation area of main exhaust pipe

　　根據工程經驗，主排煙管道的風速不能超過15m/s，否則經過一段時間的運行很容易形成排煙系統。在油煙凈化器的運行實踐中，絕大多數情況下是由于排氣管的通風面積不足造成的，且管道內的氣體流量在15m/s以上。

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

　　2. 管道的橫截面積變小

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

　　由于排煙管道必須通過施工梁，使得管道通風的截面積變小，截面上的阻力增大，形成氣流不暢通。

　　Because the smoke exhaust pipe must pass through the construction beam, the cross-sectional area of the pipe ventilation becomes smaller, the resistance on the cross-section increases, and the air flow is not smooth.

　　3.在使用管道之后，堆積會累積

　　3. After using the pipe, the accumulation will accumulate

　　當排煙管道通過施工梁或避開其他設備管道時，排煙管道的一段將低于所有排煙管道的平面。經過一段時間后，由于油水混合物會在排煙管道的下部積聚，會直接影響排煙。

　　When the smoke exhaust pipe passes through the construction beam or avoids other equipment pipes, a section of the smoke exhaust pipe will be lower than the plane of all smoke exhaust pipes. After a period of time, because the oil-water mixture will accumulate in the lower part of the smoke exhaust pipe, it will directly affect the smoke exhaust.

　　四、低層煙氣不暢通

　　4、 Low level flue gas is not smooth

　　不同樓層的廚房油煙通過同一主管道排出，靠近出口的樓層廚房排出煙作用較好，而較低樓層的廚房排出煙不自由。

　　The kitchen fume on different floors is discharged through the same main pipe. The kitchen on the floor close to the exit has a better function of discharging smoke, while the kitchen on the lower floor does not discharge smoke freely.
