Stay away from kitchen “smog”: Things to note when installing smoke exhaust ventilation ducts in commercial kitchens

Improper design and installation of smoke exhaust pipes in commercial kitchen equipment often lead to blocked smoke exhaust in the kitchen and directly affect the use of oil fume purifiers. The problems that arise during the ventilation process of kitchen equipment are, on the one hand, insufficient coordination between the kitchen process design major and the ventilation design major; on the other hand, there is a lack of experience in kitchen design and the design is not reasonable. When decorating a commercial kitchen, you must pay attention to the following issues regarding kitchen smoke exhaust and ventilation.
. The ventilation area of the main exhaust pipe is insufficient and the gas flow rate is too high. According to engineering experience, the wind speed in the main smoke exhaust duct cannot exceed /, otherwise it will easily cause the smoke exhaust system to be blocked after running for a period of time. In the operation practice of oil fume purifiers, most cases are caused by insufficient ventilation area of the exhaust pipe, and the flow rate of the gas in the pipe is / or above.
Since the smoke exhaust pipe has to pass through the building beam, the ventilation cross-sectional area of the pipe becomes smaller, and the resistance on the cross-section increases, causing the air flow to be blocked.
When the smoke exhaust duct passes through building beams or avoids other equipment ducts, a section of the smoke exhaust duct will be lower than the overall smoke exhaust duct plane. After a period of use, the oil-water mixture will accumulate in the lower section of the exhaust pipe, directly affecting the smoothness of the smoke exhaust.
. Kitchen fumes on different floors are discharged through the same main pipe. Kitchens on floors closer to the exit have better smoke exhaust effects, while kitchens on lower floors have poor smoke exhaust.
