What are the causes and solutions for the blocked smoke exhaust in the ventilation duct? The following is an introduction by the professionals of Jinan ventilation pipeline

就是设计不合理：因在开业装修时预计的就餐人员饱和值低于现今就餐饱和值，后厨工作量增加，多台灶同时作业，原设计风机转数低，排烟量小，导致排烟不畅。方法：在排烟口加装风扇式四叶或六叶排烟风机，提高排烟量，或更换大风量风机;

First of all, the design is unreasonable: due to the expected saturation value of dining staff during the opening and decoration is lower than the current saturation value, the workload of the kitchen is increased, and multiple cookers operate at the same time. The original design of fan speed is low, smoke exhaust is small, resulting in poor smoke exhaust. Solution: install a fan type four or six leaf smoke exhaust fan at the smoke exhaust outlet to increase the smoke exhaust volume or replace the high wind volume fan;

再有就是设备陈旧老化：部分厨房设备中的老式排油烟设备排油烟罩老化，导致烟罩漏风，排烟量降低。排烟风机老化导致转速降低，排烟量降低，老式排油烟设备的油烟管道都比较细(管径约300mm*300mm),因长时间积存油垢又不方便清洗，也同样导致排烟效果不好。

Another is the old equipment aging: part of the kitchen equipment in the old smoke exhaust hood aging, resulting in smoke hood air leakage, smoke reduction. The aging of exhaust fan leads to the reduction of speed and smoke exhaust. The oil fume pipes of the old oil fume exhaust equipment are relatively thin (the diameter is about 300 mm * 300 mm). Due to the oil dirt accumulated for a long time and it is not convenient to clean, the smoke exhaust effect is also not good.

还有一点就是特别重要的是要加强平时通风管道保养和清洗工作。

Another point is that it is particularly important to strengthen the maintenance and cleaning of ventilation pipes at ordinary times.
