The principle is to push the flue gas into the secondary flue through the range hood, use the driving force of the range hood and the buoyancy of the oil fume temperature to make the oil fume rise for a certain distance, and then enter the main flue and discharge it from the roof, plus the stainless steel flue decorative plate, and the flue outlet can be changed into the ceiling. If the Chinese smoke hood has no decorative plate outside the flue duct, the flue outlet needs to be changed to a proper position under the ceiling, So that the flue duct can be connected with the smoke machine through the decorative plate or from the smoke machine hanging cabinet.
Jinan kitchen smoke exhaust
Generally, there are several reasons for the noise of the smoke exhaust pipe in the hotel kitchen. According to the reasons, the remedy can be applied to the case:
1. The installation of range hood is not firm enough. If the position is not flat, the screws are loose and the parts fall off, resulting in resonance with the support and noise during work, it is necessary to reinstall the range hood or parts. The position estimation must be done to ensure correct installation.
2. The check valve is not installed correctly. For example, the check valve fails and falls off, resulting in poor smoke exhaust effect. The oil fume resonates with the check valve in the pipeline or airflow disturbance, which is prone to noise. At this time, the check valve should be reinstalled or replaced with a new check valve.
Many salesmen and even the company itself do not have this knowledge. They often design according to experience, but the whole project can not meet the required requirements. The unreasonable design and installation of ventilation pipes in Jinan often leads to poor smoke exhaust in the kitchen and directly affects the use of fume purifier. Therefore, when we install and design fume hoods in the kitchen, Pay attention to the installation of oil fume ventilation pipe. Please the ventilation duct manufacturer to install. The installation of oil fume pipeline needs to be considered from many aspects
