1、管道截面積變小
1, the section area of the pipe is smaller
排煙管道由于要穿過建筑梁而使管道通風截面積變小,截面上阻力增加,造成氣流不通暢。
Due to the crossing of the building beam, the ventilation section area of the exhaust pipe is smaller and the resistance on the section increases, resulting in the airflow is not smooth.
2、主排煙管道通風面積不夠
2. The ventilation area of the main exhaust pipe is not enough
根據工程經驗,排煙主管道內風速不能超過15m/s,否則在運行一個時期以后很容易造成排煙系統不通暢。在am8亚美登录下载的運行實踐中,大部分案例都是因排煙管道通風面積不足引起的不通暢,管道內氣體的流速都在15m/s以上。
According to the engineering experience, the wind speed in the exhaust main pipe should not exceed 15m/s, otherwise it will easily cause the smoke exhaust system to be unsmooth after a period of operation. In the operation practice of the oil fume purifier, most of the cases are caused by the insufficient ventilation area of the exhaust pipe, and the flow velocity of gas in the pipe is above 15m/s.
3、排管道使用后積聚物堆積
3. Accumulation of accumulations after pipeline use
排煙管道在穿過建筑梁或躲避其它設備管道時,排煙管道中的一段會低于整體排煙管道平面,在使用一段時間后,由于油水混合物會積聚在較低的那段排煙管道中,直接影響排煙通暢。
When the exhaust pipe is passing through the building beam or avoiding other equipment pipes, a section of the exhaust pipe will be lower than the overall exhaust pipe plane. After a period of use, the oil and water mixture will accumulate in the lower exhaust pipe, which directly affects the fluency of the exhaust.
4、建議配備排煙風機
4. Propose a smoke exhaust fan
對于油煙較大的廚房,建議還要再配備一個排煙風機。
For kitchens with larger fumes, it is suggested that a smoke exhaust fan should be equipped.
5、低層排煙不順暢
5. The low level of exhaust smoke is not smooth
不同樓層的廚房油煙通過同一主管道排出,離出口近的樓層廚房排煙效果較好,而較低樓層的廚房排煙不通暢。
The kitchen fumes from different floors are discharged through the same main pipe, and the smoke exhaust from the kitchen near the exit is better, while the kitchen exhaust smoke on the lower floor is not smooth.
