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:

　　主排气管通风面积不好

　　Poor ventilation area of main exhaust pipe

　　根据工程经验，主91短视频网站入口91短视频三级片的风速不能超过15m/s，否则经过一段时间的运行很容易形成91短视频网站入口系统。在油烟净化器的运行实践中，绝大多数情况下是由于排气管的通风面积不足造成的，且91短视频三级片内的气体流量在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. 91短视频三级片的横截面积变小

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

　　由于91短视频网站入口91短视频三级片必须通过施工梁，使得91短视频三级片通风的截面积变小，截面上的阻力增大，形成气流不畅通。

　　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91短视频三级片之后，堆积会累积

　　3. After using the pipe, the accumulation will accumulate

　　当91短视频网站入口91短视频三级片通过施工梁或避开其他设备91短视频三级片时，91短视频网站入口91短视频三级片的一段将低于所有91短视频网站入口91短视频三级片的平面。经过一段时间后，由于油水混合物会在91短视频网站入口91短视频三级片的下部积聚，会直接影响91短视频网站入口。

　　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、低层烟气不畅通

　　4、 Low level flue gas is not smooth

　　不同楼层的厨房油烟通过同一主91短视频三级片排出，靠近出口的楼层厨房排出烟作用较好，而较低楼层的厨房排出烟不自由。

　　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.
