  烟雾控制和提取系统的数据要求是什么?有关人员介绍如下:
  What are the data requirements of the smoke control and extraction system? The relevant personnel are introduced as follows:
  1)排烟管道
  1) smoke exhaust pipe
  烟气排气管的本体、结构、固定数据、密封数据、柔性接头等应选用不燃材料。
  The body, structure, fixed data, sealing data and flexible joints of flue gas exhaust pipes should be made of non-combustible materials.
  天花板内有可燃材料时,天花板内的排烟管应绝缘,不得有燃烧材料,与可燃材料的间距不得小于150mm。
  When there is combustible material in the ceiling, the smoke exhaust pipe in the ceiling should be insulated, there should be no combustible material, and the distance between the smoke exhaust pipe and the combustible material should not be less than 150 mm.
  2)正压送风管道
  2) Positive Pressure Air Supply Pipeline
  供气管道的制造应无燃烧数据。使用金属风管时,管道风速不得超过20m/s;选用光滑混凝土等非金属材料风道时,风道尺寸不得大于15m/s。
  There should be no combustion data in the manufacture of gas supply pipelines. When using metal duct, the wind speed of the duct should not exceed 20m/s; when choosing smooth concrete and other non-metallic materials, the size of the duct should not exceed 15m/s.
  增压风管通过可能发生火灾的区域时,风管的耐火极限不得小于1h。
  When the pressurized air duct passes through the area where fire may occur, the fire resistance limit of the air duct shall not be less than 1 hour.
  送风竖井应划分隔墙及相邻的耐火极限不小于lh的部位,如需在墙上设置检修门,应使用c级防火门。
  The air supply shaft should be divided into partition walls and adjacent parts whose fire resistance limit is not less than lh. If maintenance doors need to be installed on the walls, class C fire doors should be used.
  通风和空调
  Ventilation and air conditioning
  通风、空调系统管道应选用不燃材料。
  Non-combustible materials should be used in ventilation and air-conditioning systems.
  可采用耐火材料制造风管及腐蚀性介质柔性接头。
  Flexible joints of air ducts and corrosive media can be made of refractory materials.
  复合数据风管的表面数据必须为不燃数据,内部保温数据应为不燃或不燃B1级,且对人体无害。
  The surface data of composite data air duct must be non-combustible data, and the internal heat preservation data should be non-combustible or non-combustible B1 level, which is harmless to human body.
  4)保温降噪数据
  4) Data of heat preservation and noise reduction
  管道和设备绝缘数据、噪声数据和粘结剂不应焚烧或难以焚烧数据。
  Pipeline and equipment insulation data, noise data and binder data should not be burned or difficult to burn.
  a、b类厂房、仓库、高层工业建筑、影剧院、体育馆等公共建筑的供热、空调管道及设备应选用不燃材料。
  Non-combustible materials should be selected for heating and air-conditioning pipes and equipment of public buildings such as class A and B factory buildings, warehouses, high-rise industrial buildings, cinemas, gymnasiums and so on.

  烟管的制造和安装有什么要求?
  What are the requirements for the manufacture and installation of smoke pipes?
  1)风管水平装置直径或长度小于400mm时,距离不得大于4m;距离大于等于400mm的,距离不得小于3m;
  1) When the diameter or length of the horizontal device of the air duct is less than 400 mm, the distance shall not be greater than 4 m; if the distance is greater than or equal to 400 mm, the distance shall not be less than 3 m;
  2)管道应笔直,距离不应大于4m,但每个立管的固定件不应小于2个。
  2) Pipeline should be straight, distance should not be greater than 4m, but the fixed parts of each riser should not be less than 2.
  2. 带机械防排烟系统的矩形风管接头应咬合,并密封。
  2. Rectangular air duct joint with mechanical smoke control and exhaust system should be occluded and sealed.
  3.送风、排烟管道单位面积允许漏风,符合GB50243《通风空调工程施工质量检验标准》规定。供气管道允许漏气应根据工作压力确定;排烟管按照中压系统的规定。
  3. Air leakage per unit area of air supply and smoke exhaust pipes is allowed, which meets the requirements of GB50243 "Quality Inspection Standard for Ventilation and Air Conditioning Engineering Construction". The allowable leakage of gas supply pipeline should be determined according to the working pressure, and the exhaust pipe should be determined according to the regulation of medium pressure system.
  4. 管道与风机的连接应选用法兰连接或无燃烧材料的柔性连接。
  4. Flange connection or flexible connection without combustible material should be selected for the connection between pipeline and fan.
  5. 管道通过隔墙时,管道与隔墙之间的缝隙应用水泥砂浆等非焚烧材料密实填充。
  5. When the pipeline passes through the partition wall, the gap between the pipeline and the partition wall is filled with non-incinerating materials such as cement mortar.
  6. 排烟管隔热层采用厚度不小于40mm的不燃保温材料(如矿棉、岩棉、硅酸铝等)隔热。
  6. The smoke pipe insulation layer is insulated by non-combustible insulation materials (such as mineral wool, rock wool, aluminium silicate, etc.) whose thickness is not less than 40 mm.
