音速超细干粉灭火装置是一种创新型灭火设备，其核心技术在于利用超音速气流将超细干粉灭火剂高速喷射至火场，实现快速灭火。该装置利用固体火箭发动机的原理，产生高速飞流，以每秒800米的速度喷向火场。火焰在超音速气流的作用下，燃烧链被切割。被气化的干粉经受热起化学反应，生成多聚磷酸盐，覆盖在着火表面上，并渗透可燃物的气孔内，阻止空气与可燃物的接触。这一独特的灭火机理使音速超细干粉灭火装置能够在出彩短时间内扑灭火灾。
The supersonic ultra-fine dry powder fire extinguishing device is an innovative fire extinguishing equipment, whose core technology is to use supersonic airflow to spray ultra-fine dry powder fire extinguishing agent at high speed to the fire scene, achieving rapid fire extinguishing. The device utilizes the principle of a solid rocket engine to generate a high-speed jet that sprays towards the fire at a speed of 800 meters per second. Under the action of supersonic airflow, the flame cuts the combustion chain. The vaporized dry powder undergoes a thermal chemical reaction to generate polyphosphates, which cover the ignition surface and penetrate into the pores of the combustible material, preventing contact between air and the combustible material. This unique fire extinguishing mechanism enables the supersonic ultra-fine dry powder fire extinguishing device to extinguish fires in a very short time.
超细干粉灭火剂是装置的核心灭火介质，其平均粒径通常不大于5微米。与普通干粉灭火剂相比，超细干粉具有以下显著优点：首先，具备气体灭火剂的动力性质，有利于灭火剂扩散和分布，可以达到全淹没灭火的目的；其次，粒子被粉碎后分散度增高，总面积提升，出彩易与周围介质相互作用，灭火效能大幅度提高，火场上已经被扑灭的火焰不可能再复燃；第三，干粉本身及其灭火后的残留物性质稳定。超细干粉灭火剂采用超细粒径、超优性能粉体后，具有自动防潮等特点，使灭火能力成倍增强。
Ultra fine dry powder fire extinguishing agent is the core fire extinguishing medium of the device, and its average particle size is usually not greater than 5 microns. Compared with ordinary dry powder fire extinguishing agents, ultrafine dry powder has the following significant advantages: firstly, it has the dynamic properties of gas fire extinguishing agents, which is conducive to the diffusion and distribution of fire extinguishing agents, and can achieve the goal of total flooding fire extinguishing; Secondly, after being crushed, the dispersion of particles increases, the total area increases, and they are easily interacted with the surrounding medium, greatly improving the fire extinguishing efficiency. Flames that have already been extinguished on the fire scene cannot be reignited; Thirdly, the properties of the dry powder itself and its residual after extinguishing are stable. The ultra-fine dry powder fire extinguishing agent adopts ultra-fine particle size and excellent performance powder, which has the characteristics of automatic moisture-proof, greatly enhancing the fire extinguishing ability.
音速超细干粉灭火装置的结构设计也颇具特色。典型的装置包括粉罐体、上封口组件、喷发剂盒组件和喷口组件。粉罐体内充填超细干粉灭火剂，上封口由上封口罩和连接的上螺母构成。装置可采用定温启动、热引发启动或电引发启动等多种启动方式，电引发和热引发启动方式都附带定温启动，实现双重保险。接通电流后电爆管引爆火药爆炸喷发灭火剂，亦能实现多具联动。装置还设有超速、油压低、三次启动失败等多重保护功能，确保运行安全可靠。
The structural design of the supersonic ultra-fine dry powder fire extinguishing device is also quite distinctive. A typical device includes a powder tank, an upper sealing component, a spray box component, and a nozzle component. The powder can is filled with ultra-fine dry powder fire extinguishing agent, and the upper seal is composed of an upper sealing mask and a connected upper nut. The device can adopt various starting methods such as constant temperature start, thermal start, or electric start. Both electric and thermal start methods come with constant temperature start, achieving dual safety. After connecting the current, the electric explosive tube can detonate the gunpowder and spray the fire extinguishing agent, which can also achieve multi device linkage. The device is also equipped with multiple protection functions such as overspeed, low oil pressure, and three failed starts to ensure safe and reliable operation.
这种装置不仅能快速扑灭烟草行业的火灾，还广泛应用于石油化工、电力设施、通讯基站等场所。其超音速喷射带来的强大穿透力和覆盖能力，使其在复杂火灾场景中具有独特优势。
This device can not only quickly extinguish fires in the tobacco industry, but is also widely used in places such as petrochemicals, power facilities, and communication base stations. The powerful penetration and coverage capabilities brought by its supersonic jet give it a unique advantage in complex fire scenarios.
