厨房安装排烟管道要考虑的五方面问题

厨房排烟管道很重要，安装使用时一定要特别注意几个事项，比如管道的通风面积，低层排烟不畅，如下：

The smoke exhaust pipe in the kitchen is very important. During installation and use, special attention must be paid to several matters, such as the ventilation area of the pipe and the poor smoke exhaust on the lower floor, as follows:

排烟管道

Smoke exhaust pipe

一、主排气管通风面积不足。

1、 The ventilation area of the main exhaust pipe is insufficient.

根据工程经验，主排气管内风速不能超过15m/s，否则运行一段时间后排气系统容易堵塞。在油烟净化器的运行实践中，大多数情况是由于排气管通风面积不足造成的，管内气体流速在15m/s以上。

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

二、管道截面积变小。

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

由于排烟管道会穿过建筑横梁，导致气流不畅，排气管的通风横截面积会减小，横截面上的阻力会增加。

As the smoke exhaust pipe will pass through the building beam, resulting in poor airflow, the ventilation cross-sectional area of the exhaust pipe will be reduced, and the resistance on the cross-section will be increased.

三、管道使用后会堆积。

3、 Pipes will accumulate after use.

当排烟管道穿过建筑横梁或避开其他设备管道时，一段排烟管会低于整个排烟管的平面。使用一段时间后，油水混合物会堆积在排烟管的下部，直接影响排烟的顺畅性。

When the smoke exhaust pipe passes through the building beam or avoids other equipment pipes, a section of smoke exhaust pipe will be lower than the plane of the whole smoke exhaust pipe. After using for a period of time, the oil-water mixture will accumulate in the lower part of the smoke exhaust pipe, directly affecting the smoothness of smoke exhaust.

四、低层排烟不顺畅

4、 Smoke exhaust on the lower floor is not smooth

不同楼层的厨房油烟通过同一主管道排出，靠近出口的楼层排烟效果较好，而较低楼层排烟不畅。

The kitchen fume of different floors is discharged through the same main pipe. The smoke exhaust effect of the floor near the exit is better, while the smoke exhaust of the lower floor is not smooth.

五、建议配备排烟风机

5、 Smoke exhaust fan is recommended

对于高油烟的厨房，建议配备排烟风机。常用的排烟风机有轴流风机、风机箱和离心风机。

For kitchens with high oil smoke, it is recommended to provide smoke exhaust fans. The commonly used smoke exhaust fans include axial flow fans, fan boxes and centrifugal fans.
