干粉滅火器在工作時運用到的原理：滅火劑則經過總閥門、選擇閥、輸粉管和噴嘴向著火對象，或者經噴槍射到著火對面的表面，粉霧與火焰接觸、混合，發生一系列物理和化學作用，達到滅火的作用。干粉滅火系統由干粉滅火設備和火災自動探測控制兩部分組成。接下來川消小編將簡單介紹干粉滅火系統工作原理是什么以及干粉滅火系統由什么組成！

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!

干粉滅火系統工作原理是什么？

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

干粉滅火器內部裝有磷酸銨鹽等干粉滅火劑，這種干粉滅火劑具有易流動性、干燥性，由無機鹽和粉碎干燥的添加劑組成，可有效撲救初期火災。那么它的滅火機理和原理你知道嗎？

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、滅火機理

1. Fire extinguishing mechanism

干粉在滅火過程中，粉霧與火焰接觸，混合，發生一系列物理和化學作用，既具有化學滅火劑的作用，同時又具有物理抑制劑的特點，其滅火機理主要為：化學抑制作用、隔離作用和冷卻與窒息作用。

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

利用氮氣瓶組內的高壓氮氣經減壓閥減壓后，使氮氣進入干粉罐，其中一部分被送到罐的底部，起到松散干粉滅火劑的作用。當干粉罐內的壓力升到規定壓力數值時，定壓動作機構開始動作，打開干粉罐出口球閥，干粉滅火劑則經過總閥門、選擇閥、輸粉管和噴嘴向著火對象，或者經噴槍射到著火對面的表面，進行滅火。

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.

干粉滅火系統由什么組成？

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

在安裝干粉滅火系統時，要知道它的組成部分，這樣才能更好地使用，那么干粉滅火系統是由哪些部分組成呢？

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?

干粉滅火系統主要由兩部分組成，即干粉滅火設備部分和火災自動探測控制部分。

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）干粉滅火部分由干粉儲罐、動力氣瓶、減壓閥、輸粉管道以及噴嘴等組成。

(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）火災自動探測控制部分有火災探測器、啟動瓶、報警控制器等設備。

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