廠房通風管道1防火性能好：當前普遍存在的問題是成品通風道燃燒性能和耐火極限未經有關部門檢測，且部分通風道材料的燃燒性能、管壁厚度不符合要求。
Good fire performance of ventilation duct 1 in the power house: at present, the common problem is that the combustion performance and fire resistance limit of the finished ventilation duct have not been tested by the relevant departments, and the combustion performance and pipe wall thickness of some ventilation duct materials do not meet the requirements.
進行應用的廠房通風管道，在很大的程度上其實也就是能直接的就減少地下室通風上部空間占用以及其風管用量。地下室通風方式合理，就其在進行布置的時候，排風管及排風口，平時排風用，火災的時候必然會兼作排煙風管與排煙口。增加了室內空間，密閉性好、不返煙、不返臭，能大幅度改善室內環(huán)境。
To a large extent, the ventilation duct of the workshop which is applied professionally can directly reduce the occupation of the upper space of the basement ventilation and the amount of its air duct. The ventilation mode of the basement is reasonable. When it is arranged, the exhaust duct and air outlet are usually used for air exhaust. In case of fire, they must be used as both smoke exhaust duct and smoke outlet. The indoor environment can be greatly improved by increasing the indoor space, good airtightness, no return of smoke and odor.
在進行廠房通風管道1設計的時候，污水處理設備還要考慮一下排風、排煙方面的措施。對于普通離心風機本身也就是能滿足排風排煙方面的要求，但是大風量離心風機只可以安裝在地面上，不過就其占地比較大，需要較大機房，高溫軸流風機為消防專用風機，這時候也就是能滿足在280℃ 煙溫之下運行30 min的要求
In the design of ventilation pipe 1 of the power house, the measures of air exhaust and smoke exhaust should be considered for the sewage treatment equipment. For ordinary centrifugal fans, they can meet the requirements of exhaust and smoke exhaust. However, large volume centrifugal fans can only be installed on the ground, but they occupy a large area and need a large machine room. High temperature axial flow fans are special fans for fire protection. At this time, they can meet the requirements of 30 min operation under 280 ℃ smoke temperature
