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

首先就是設計不合理：因在開業裝修時預計的就餐人員飽和值低于現今就餐飽和值，后廚工作量增加，多臺灶同時作業，原設計風機轉數低，排煙量小，導致排煙不暢。解決方法：在排煙口加裝風扇式四葉或六葉排煙風機，提高排煙量，或更換大風量風機;

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;

再有就是設備陳舊老化：部分廚房設備中的老式排油煙設備排油煙罩老化，導致煙罩漏風，排煙量降低。排煙風機老化導致轉速降低，排煙量降低，老式排油煙設備的油煙管道都比較細(管徑約300mm*300mm),因長時間積存油垢又不方便清洗，也同樣導致排煙效果不好。

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.

還有一點就是特別重要的是要加強平時通風管道保養和清洗工作。

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