气体灭火系统凭借其独特的优势和广泛的使用范围赢得了社会的认同，在消防灭火系统中占据重要的地位。那么气体灭火系统根据保护方式分全应用局部应用的相关内容是怎样的？
With its unique advantages and wide application range, gas fire extinguishing system has won the recognition of the society and occupies an important position in the fire extinguishing system. Then, what are the relevant contents of full application and local application of gas fire extinguishing system according to the protection mode?
它是以气体为灭火介质的灭火系统，通常用在不适宜用水灭火系统来进行灭火的场所，比如通讯机房、图书档案馆、移动通信基站、电池室、柴油发电机房、工业除尘设备、喷漆房等。气体灭火系统是将灭火剂以气体或液体状态储存于压力容器内，灭火时以气体（包括蒸汽、气雾）状态进行喷射。
It is a fire extinguishing system with gas as the fire extinguishing medium. It is usually used in places that are not suitable for fire extinguishing with water fire extinguishing system, such as communication machine room, library and archives, mobile communication base station, battery room, diesel generator room, industrial dust removal equipment, paint spraying room, etc. The gas fire extinguishing system is to store the fire extinguishing agent in the pressure vessel in the state of gas or liquid, and spray it in the state of gas (including steam and mist).
气体灭火系统通常会根据保护场所和对象的特点进行选择保护方式，分为全应用和局部应用：
The gas fire extinguishing system usually selects the protection mode according to the characteristics of the protection place and object, which is divided into full application and local application:
全应用是指在规定时间内向防护区喷射一定浓度的灭火剂并使其均匀地充满整个防护区。各类气体灭火剂均适用于此系统。局部应用是指向保护对象以设计喷射强度直接喷射灭火剂并持续一定时间。目前，二氧化碳灭火系统是可用于全淹没灭火系统也可用于局部应用灭火系统的气体灭火剂。
Full application refers to spraying a certain concentration of fire extinguishing agent into the protection area within a specified time and making it evenly fill the whole protection area. All kinds of gas fire extinguishing agents are suitable for this system. Local application refers to direct spraying of fire extinguishing agent to the protected object with designed spraying intensity and lasting for a certain period of time. At present, carbon dioxide fire extinguishing system is the only gas fire extinguishing agent that can be used in total flooding fire extinguishing system and local application fire extinguishing system.
局部应用灭火系统只能用于扑灭不具备封闭空间条件的特定保护对象的表面火灾，如钢厂的轧机生产线、印刷机、电站、干燥设备、浸油槽、汽车厂涂装生产线等局部保护。无法扑灭深火。
Local application fire extinguishing system can only be used to extinguish the surface fire of specific protected objects without closed space conditions, such as rolling mill production line, printing press, power station, drying equipment, oil immersion tank, coating production line of automobile factory and other local protection. Unable to put out the deep fire.
气体灭火系统适用于扑救能在灭火前切断气源的电气火灾、固体表面火灾、液体火灾和气体火灾。这是从广义上规定的，具体应指不适合防水或灭火的场所或物体。如电子电气设备、通讯设备、易燃易燃液体和气体、贵重物品和财产存放场所。
The gas fire extinguishing system is suitable for extinguishing electrical fires, solid surface fires, liquid fires and gas fires that can cut off the gas source before fire extinguishing. This is stipulated in a broad sense, and specifically refers to places or objects that are not suitable for waterproof or fire extinguishing. Such as electronic and electrical equipment, communication equipment, flammable liquids and gases, valuables and property storage places.
各种气体灭火系统适用于扑救液体火灾（B型火灾），二氧化碳和三氟甲烷也适用于扑救石蜡、沥青等可熔化的固体火灾。但对于IG-541灭火系统，由于其灭火效率相对较低，在高压喷涂时可能会造成易燃易燃液体的飞溅和汽化，从而导致火势蔓延，在燃料是液体的地方燃烧。
Various gas fire extinguishing systems are suitable for extinguishing liquid fires (type B fires), carbon dioxide and trifluoromethane are also suitable for extinguishing fusible solid fires such as paraffin wax and asphalt. However, for IG-541 fire extinguishing system, due to its relatively low fire extinguishing efficiency, splashing and vaporization of flammable liquid may be caused during high-pressure spraying, resulting in fire spread and burning where the fuel is liquid.
川消提醒您，对于气体火灾，无论选用哪种气体灭火系统，都要求在喷洒灭火剂前能切断气体供应。即在设计时应注意并提醒燃气设计人员，并在燃气管道上安装紧急自动切断装置。采取该措施的主要目的是防止可燃气体的积聚引起爆炸，二是防止可燃气体的连续逸出，稀释灭火剂的浓度，影响灭火。
Chuanxiao reminds you that for gas fires, no matter what kind of gas fire extinguishing system is selected, it is required to cut off the gas supply before spraying fire extinguishing agent. That is, professional gas designers shall be noticed and reminded during design, and emergency automatic cut-off device shall be installed on gas pipeline. The main purpose of taking this measure is to prevent the accumulation of combustible gas from causing explosion. The second is to prevent the continuous escape of combustible gas, dilute the concentration of fire extinguishing agent and affect the fire extinguishing.
The gas fire extinguishing system is divided into full application and local application according to the protection mode. Chuanxiao will explain here for you. For more information about fire fighting and fire-fighting equipment, please visit www.cx-fire.com Check it out. Www. 68mn.
