在山东的高楼大厦与工业厂房中，通风管道宛如建筑的 “呼吸脉络”，排烟系统则是关键时刻的 “生命通道”。然而，这条 “通道” 一旦引发火灾，后果不堪设想。尤其在山东四季分明、工业活动频繁的环境下，给通风管道构筑坚固的 “防火墙”，成为狙击排烟火灾的关键战役。从材料选择到日常维护，每一个环节都是这场攻防战的重要防线。

　　In the high-rise buildings and industrial plants in Shandong, ventilation ducts are like the "breathing veins" of the building, and smoke exhaust systems are the "life passages" at critical moments. However, if this' passage 'triggers a fire, the consequences would be unimaginable. Especially in the environment of four distinct seasons and frequent industrial activities in Shandong, building a strong "firewall" for ventilation ducts has become a key battle for sniping smoke exhaust fires. From material selection to daily maintenance, every link is an important defense line in this offensive and defensive battle.

　　筑牢防火材料防线：材料是抵御火灾的第一道关卡。山东地区的通风管道应优先选用不燃材料，像优质的镀锌钢板，凭借表面镀锌层的保护，不仅具备良好的抗腐蚀性能，还能在高温下保持稳定，不会燃烧助火。还有无机玻璃钢材质，它由无机胶凝材料与增强材料复合而成，本身不具备可燃性，且在火灾发生时能有效阻隔热量传递，延缓火势蔓延。在排烟系统关键部位，如与火源可能直接接触的区域，可采用防火岩棉板包裹通风管道。岩棉板是一种以天然岩石为主要原料制成的不燃性纤维材料，具有出色的隔热和防火性能，能像 “防火铠甲” 一样，为管道提供额外保护，降低火灾风险。

　　Building a strong defense line with fire-resistant materials: Materials are the first line of defense against fires. Ventilation ducts in Shandong region should prioritize the use of non combustible materials, such as high-quality galvanized steel plates. With the protection of the surface galvanized layer, they not only have good corrosion resistance, but also maintain stability at high temperatures and will not burn or ignite. There is also inorganic fiberglass material, which is composed of inorganic cementitious materials and reinforcement materials. It does not have flammability itself and can effectively block heat transfer and delay the spread of fire in the event of a fire. Fire resistant rock wool boards can be used to wrap ventilation ducts in critical areas of the smoke exhaust system, such as areas that may come into direct contact with fire sources. Rock wool board is a non combustible fiber material made mainly from natural rocks, which has excellent thermal insulation and fire resistance properties. It can provide additional protection for pipelines like "fireproof armor" and reduce the risk of fire.

　　优化设计构建安全网络：合理的管道设计如同精密的作战部署。排烟管道的布局要避免出现死角和弯折过多的情况，因为复杂的管道结构容易导致油烟、热气积聚，增加火灾隐患。管道的走向应尽量简洁流畅，减少不必要的弯道，确保烟气能够迅速排出。同时，科学设置防火阀至关重要。防火阀就像忠诚的 “防火哨兵”，在管道内温度达到一定阈值（通常为 70℃或 280℃ ，根据不同场景设定）时，会自动关闭，切断烟气和火势蔓延的途径。在山东的大型商业建筑中，可在通风管道穿越防火分区、机房等重要部位设置防火阀，将火灾控制在有限区域内。此外，管道的风速设计也不容忽视，风速过低会使油烟附着在管道内壁，形成易燃的油垢；风速过高则可能产生静电，引发火灾。因此，要根据实际排烟需求，精确计算并控制管道内的风速，让烟气既能快速排出，又不会带来额外风险。

　　Optimizing design to build a secure network: Reasonable pipeline design is like precise combat deployment. The layout of smoke exhaust pipes should avoid dead corners and excessive bends, as complex pipe structures can easily lead to the accumulation of oil fumes and hot gases, increasing fire hazards. The direction of the pipeline should be as simple and smooth as possible, reducing unnecessary bends to ensure that smoke can be quickly discharged. Meanwhile, it is crucial to scientifically install fire dampers. Fire dampers are like loyal 'fire sentinels', automatically closing when the temperature inside the pipeline reaches a certain threshold (usually 70 ℃ or 280 ℃, set according to different scenarios), cutting off the path of smoke and fire spread. In large commercial buildings in Shandong, fire dampers can be installed in important areas such as ventilation ducts passing through fire compartments and computer rooms to control fires within a limited area. In addition, the wind speed design of the pipeline cannot be ignored. If the wind speed is too low, oil fumes will adhere to the inner wall of the pipeline, forming flammable oil stains; If the wind speed is too high, it may generate static electricity and cause a fire. Therefore, it is necessary to accurately calculate and control the wind speed inside the pipeline according to the actual smoke exhaust demand, so that the smoke can be quickly discharged without bringing additional risks.

　　强化日常维护与监测：日常维护和监测是持续作战的后勤保障。排烟系统的清洁工作必不可少，山东地区的餐饮场所、工业车间等，由于油烟、粉尘较多，更需要定期清理通风管道内部。专业人员可使用高压清洗设备，对管道内壁的油垢、积尘进行彻底清除，防止这些易燃物质成为火灾的导火索。同时，建立定期巡检制度，安排专人对通风管道、防火阀、风机等排烟系统设备进行检查。查看管道是否有破损、裂缝，防火阀能否正常关闭，风机运行是否正常等，一旦发现问题及时修复。随着科技发展，还可引入智能监测系统，利用传感器实时监测管道内的温度、烟雾浓度等参数。当数据出现异常时，系统立即发出警报，提醒工作人员采取措施，实现对火灾隐患的早发现、早处理。

　　Strengthen daily maintenance and monitoring: Daily maintenance and monitoring are the logistical support for continuous operations. The cleaning work of the smoke exhaust system is essential. In catering establishments, industrial workshops, etc. in Shandong region, due to the high amount of oil fume and dust, it is even more necessary to regularly clean the interior of the ventilation ducts. Professional personnel can use high-pressure cleaning equipment to thoroughly remove oil and dust deposits on the inner walls of pipelines, preventing these flammable substances from becoming the trigger of fires. At the same time, establish a regular inspection system and assign dedicated personnel to inspect smoke exhaust system equipment such as ventilation ducts, fire dampers, and fans. Check whether the pipeline is damaged or cracked, whether the fire damper can be closed normally, whether the fan is running normally, etc. Once any problems are found, repair them in a timely manner. With the development of technology, intelligent monitoring systems can also be introduced to use sensors to monitor real-time parameters such as temperature and smoke concentration inside pipelines. When there is an abnormality in the data, the system immediately issues an alarm to remind the staff to take measures to achieve early detection and handling of fire hazards.

　　提升人员应急能力：人员是这场攻防战的核心力量。在山东的各类建筑场所，要加强对工作人员的消防安全培训，让他们熟悉排烟系统的操作流程和火灾应急处理方法。定期组织消防演练，模拟排烟系统火灾场景，训练工作人员在火灾发生时迅速启动应急排烟设备、引导人员疏散等技能。通过演练，提高人员的应急反应能力和协同作战水平，确保在真实火灾来临时，能够有条不紊地应对，最大限度减少火灾损失。

　　Enhance personnel emergency response capability: Personnel are the core force in this offensive and defensive battle. In various construction sites in Shandong, it is necessary to strengthen fire safety training for staff, so that they are familiar with the operation process of smoke exhaust systems and fire emergency response methods. Regularly organize fire drills, simulate smoke exhaust system fire scenarios, train staff to quickly activate emergency smoke exhaust equipment and guide personnel evacuation skills in the event of a fire. Through drills, we aim to enhance personnel's emergency response capabilities and collaborative combat skills, ensuring that they can respond in an orderly manner when a real fire occurs, and minimize fire losses to the greatest extent possible.

　　在山东，为通风管道的排烟系统构筑 “防火墙”，需要从材料、设计、维护、人员等多维度协同作战。只有将每一道防线筑牢，才能让通风管道在保障建筑 “呼吸” 顺畅的同时，成为抵御火灾的坚固堡垒，守护一方安全。

　　In Shandong, building a "firewall" for the exhaust system of ventilation ducts requires collaborative efforts from multiple dimensions such as materials, design, maintenance, and personnel. Only by strengthening every line of defense can ventilation ducts become a strong fortress against fires and safeguard the safety of the building while ensuring smooth "breathing".
