氣體滅火系統(tǒng)憑借其獨特的優(yōu)勢和廣泛的使用范圍贏得了社會的認同，在消防滅火系統(tǒng)中占據(jù)重要的地位。那么氣體滅火系統(tǒng)根據(jù)保護方式分全應用局部應用的相關內(nèi)容是怎樣的？
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?
它是以氣體為滅火介質(zhì)的滅火系統(tǒng)，通常用在不適宜用水滅火系統(tǒng)來進行滅火的場所，比如通訊機房、圖書檔案館、移動通信基站、電池室、柴油發(fā)電機房、工業(yè)除塵設備、噴漆房等。氣體滅火系統(tǒng)是將滅火劑以氣體或液體狀態(tài)儲存于壓力容器內(nèi)，滅火時以氣體（包括蒸汽、氣霧）狀態(tài)進行噴射。
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).
氣體滅火系統(tǒng)通常會根據(jù)保護場所和對象的特點進行選擇保護方式，分為全應用和局部應用：
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:
全應用是指在規(guī)定時間內(nèi)向防護區(qū)噴射一定濃度的滅火劑并使其均勻地充滿整個防護區(qū)。各類氣體滅火劑均適用于此系統(tǒng)。局部應用是指向保護對象以設計噴射強度直接噴射滅火劑并持續(xù)一定時間。目前，二氧化碳滅火系統(tǒng)是可用于全淹沒滅火系統(tǒng)也可用于局部應用滅火系統(tǒng)的氣體滅火劑。
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.
局部應用滅火系統(tǒng)只能用于撲滅不具備封閉空間條件的特定保護對象的表面火災，如鋼廠的軋機生產(chǎn)線、印刷機、電站、干燥設備、浸油槽、汽車廠涂裝生產(chǎn)線等局部保護。無法撲滅深火。
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.
氣體滅火系統(tǒng)適用于撲救能在滅火前切斷氣源的電氣火災、固體表面火災、液體火災和氣體火災。這是從廣義上規(guī)定的，具體應指不適合防水或滅火的場所或物體。如電子電氣設備、通訊設備、易燃易燃液體和氣體、貴重物品和財產(chǎn)存放場所。
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.
各種氣體滅火系統(tǒng)適用于撲救液體火災（B型火災），二氧化碳和三氟甲烷也適用于撲救石蠟、瀝青等可熔化的固體火災。但對于IG-541滅火系統(tǒng)，由于其滅火效率相對較低，在高壓噴涂時可能會造成易燃易燃液體的飛濺和汽化，從而導致火勢蔓延，在燃料是液體的地方燃燒。
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，對于氣體火災，無論選用哪種氣體滅火系統(tǒng)，都要求在噴灑滅火劑前能切斷氣體供應。即在設計時應注意并提醒燃氣設計人員，并在燃氣管道上安裝緊急自動切斷裝置。采取該措施的主要目的是防止可燃氣體的積聚引起爆炸，二是防止可燃氣體的連續(xù)逸出，稀釋滅火劑的濃度，影響滅火。
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.
