        酒店機械排煙系統是怎么設計的?

        來源:http://www.boursomarket.com 日期:2019-10-08 發布人:admin

          機械排煙系統可以有效地排除大量人員,保證火災發生時人員的安全。下面小編從機械排煙方式、排煙系統布局、排煙方式等方面進行防排煙設計,希望對大家有所幫助。
          Mechanical smoke exhaust system can effectively eliminate a large number of personnel, to ensure the safety of personnel in the event of fire. The following small weave from the mechanical smoke exhaust mode, smoke exhaust system layout, smoke exhaust mode and other aspects of smoke prevention and exhaust design, I hope to help you.
          一、機械排煙
          I. Mechanical smoke exhaust
          1. 局部排煙:每個空間區域設置風機,將室外煙氣抽走。
          1. Local smoke exhaust: Each space area is equipped with a fan to remove outdoor smoke.
          2. 集中排煙:利用排煙風機,通過管道收集和排出多個區域的煙氣。
          2. Centralized smoke exhaust: using smoke exhaust fan, collecting and discharging smoke from multiple areas through pipelines.
          二是機械排煙部件
          Second, mechanical smoke exhaust components
          1. 沒有直接自然通風但長度超過20米的人行道或直接自然通風但長度超過60米的人行道。
          1. Pedestrians with no direct natural ventilation but over 20 meters in length or those with direct natural ventilation but over 60 meters in length.
          2. 沒有窗戶的房間,面積超過100平方米,有大量的居住者或火爐。
          2. A room without windows, covering an area of more than 100 square meters, has a large number of residents or stoves.
          3.除了可用的窗戶和水井外,200平方米以上或50平方米以上的高可燃性、經常有人居住的房間或地下室,沒有自然排煙條件,也沒有凈空超過12米的中庭。
          3. Apart from the windows and wells available, there are no natural smoke exhaust conditions and no atrium with a clearance of more than 12 meters in highly flammable rooms or basements, which are more than 200 square meters or over 50 square meters.

          1. 內走道機械排煙系統。內走道通常垂直布置。
          1. Mechanical smoke exhaust system in Inner aisle. The inner aisle is usually arranged vertically.
          2. 多室機械排煙系統。通常采用水平排列。
          2. Multi-room mechanical smoke exhaust system. Usually it is arranged horizontally.
          4. 煙氣排放計算
          4. Flue gas emission calculation
          1. 風機進行隔煙時,每平方米小風量不低于60立方米,單臺風機小風量不低于7200m3/h。
          1. When the fan is used for smoke isolation, the minimum air volume per square metre is less than 60 cubic metres, and the minimum air volume per fan is less than 7200 m3/h.
          2. 當風機進行2個以上分區時,大排煙量為60000m3/h,按不小于120立方米/平方米計算。
          2. When the fan is divided into more than two zones, the maximum smoke exhaust capacity is 60,000 m3/h, calculated at no less than 120 cubic meters/square meters.
