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!
The main reasons are as follows:
Poor ventilation area of main exhaust pipe
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. The cross-sectional area of the pipeline becomes smaller
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. After using the pipe, the accumulation will accumulate
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.
4、 Low level flue gas is not smooth
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.
