干粉灭火器在工作时运用到的原理：灭火剂则经过总阀门、选择阀、输粉管和喷嘴向着火对象，或者经喷枪射到着火对面的表面，粉雾与火焰接触、混合，发生一系列物理和化学作用，达到灭火的作用。干粉灭火系统由干粉灭火设备和火灾自动探测控制两部分组成。接下来川消小编将简单介绍干粉灭火系统工作原理是什么以及干粉灭火系统由什么组成！

The principle used in the operation of dry powder fire extinguishers is that the extinguishing agent passes through the main valve, selector valve, powder conveying pipe, and nozzle towards the object of fire, or is sprayed onto the surface opposite the fire through the spray gun. The powder mist contacts and mixes with the flame, and a series of physical and chemical reactions occur to achieve the effect of extinguishing fire. The dry powder fire extinguishing system consists of two parts: dry powder fire extinguishing equipment and automatic fire detection and control. Next, the editor of Chuanxiao will briefly introduce the working principle of the dry powder fire extinguishing system and what it consists of!

干粉灭火系统工作原理是什么？

What is the working principle of a dry powder fire extinguishing system?

干粉灭火器内部装有磷酸铵盐等干粉灭火剂，这种干粉灭火剂具有易流动性、干燥性，由无机盐和粉碎干燥的添加剂组成，可有效扑救初期火灾。那么它的灭火机理和原理你知道吗？

The dry powder extinguisher is equipped with dry powder extinguishing agent such as ammonium phosphate, which is easy to flow and dry. It is composed of inorganic salt and crushed and dried additives, and can effectively put out initial fires. Do you know its fire extinguishing mechanism and principle?

1、灭火机理

1. Fire extinguishing mechanism

干粉在灭火过程中，粉雾与火焰接触，混合，发生一系列物理和化学作用，既具有化学灭火剂的作用，同时又具有物理抑制剂的特点，其灭火机理主要为：化学抑制作用、隔离作用和冷却与窒息作用。

During the fire extinguishing process, dry powder contacts and mixes with the flame, resulting in a series of physical and chemical reactions. It not only acts as a chemical extinguishing agent, but also has the characteristics of a physical inhibitor. Its fire extinguishing mechanism mainly includes chemical inhibition, isolation, and cooling and suffocation.

2、工作原理

2. Working principle

利用氮气瓶组内的高压氮气经减压阀减压后，使氮气进入干粉罐，其中一部分被送到罐的底部，起到松散干粉灭火剂的作用。当干粉罐内的压力升到规定压力数值时，定压动作机构开始动作，打开干粉罐出口球阀，干粉灭火剂则经过总阀门、选择阀、输粉管和喷嘴向着火对象，或者经喷枪射到着火对面的表面，进行灭火。

After the high-pressure nitrogen in the nitrogen cylinder group is depressurized by the pressure reducing valve, the nitrogen enters the dry powder tank, and a portion of it is sent to the bottom of the tank to act as a loose dry powder extinguishing agent. When the pressure inside the dry powder tank rises to the specified pressure value, the constant pressure action mechanism begins to operate, opening the outlet ball valve of the dry powder tank. The dry powder extinguishing agent then passes through the main valve, selection valve, powder conveying pipe, and nozzle to the object of fire, or is sprayed onto the surface opposite the fire through the spray gun to extinguish the fire.

干粉灭火系统由什么组成？

What is the composition of a dry powder fire extinguishing system?

在安装干粉灭火系统时，要知道它的组成部分，这样才能更好地使用，那么干粉灭火系统是由哪些部分组成呢？

When installing a dry powder fire extinguishing system, it is important to know its components in order to use it better. So, what are the components of a dry powder fire extinguishing system?

干粉灭火系统主要由两部分组成，即干粉灭火设备部分和火灾自动探测控制部分。

The dry powder fire extinguishing system mainly consists of two parts, namely the dry powder fire extinguishing equipment part and the automatic fire detection and control part.

（1）干粉灭火部分由干粉储罐、动力气瓶、减压阀、输粉管道以及喷嘴等组成。

(1) The dry powder extinguishing section consists of a dry powder storage tank, a power cylinder, a pressure reducing valve, a powder conveying pipeline, and a nozzle.

（2）火灾自动探测控制部分有火灾探测器、启动瓶、报警控制器等设备。

(2) The automatic fire detection and control section includes equipment such as fire detectors, starter bottles, and alarm controllers.
