I. insufficient ventilation area of main exhaust pipe
According to engineering experience, the wind speed in the main smoke exhaust pipe should not exceed 15 m/s, otherwise the smoke exhaust system will be blocked easily after a period of operation. In the operation practice of lampblack purifier, most cases are caused by insufficient ventilation area of exhaust pipe, and the gas flow rate in the pipe is above 15m/s.
II. Reduction of Pipeline Section Area
The ventilation cross-section area of the smoke exhaust pipeline is reduced and the resistance on the cross-section is increased due to the passage of the smoke exhaust pipeline through the building beams, resulting in the airflow obstruction.
3. Accumulation after the use of drainage pipes
When the smoke exhaust pipe passes through the building beam or evades other equipment pipelines, one section of the smoke exhaust pipe will be lower than the overall smoke exhaust pipe plane. After using for a period of time, the oil-water mixture will accumulate in the lower section of the smoke exhaust pipe, which directly affects the smooth smoke exhaust.
4. Smoke exhaust at low level is not smooth
The kitchen fumes of different floors are discharged through the same main pipe. The smoke exhaust effect of the kitchen on the floor near the exit is better, while the smoke exhaust of the kitchen on the lower floor is not smooth.
