一、概述:Outline

管道阻火器是适用于石化、化工、轻工等行业的可燃气体输送过程中的安全装置。厂生产制造的管道阻火器是经过严谨的阻火理论设计和精密专用的机械设备加工制造而成的。根据阻火性能和阻火等级可分为阻爆燃型和阻爆轰型两大类。

Pipeline Fire is the safety devices applicable to the petrochemical, chemical, light industry, combustible gas delivery process. I plant manufacturing Pipeline Fire is made ??after the a rigorous the flame arrester theory of design and precision dedicated processing machinery and equipment. According to fire resistance and fire retardant class can be divided into the the deflagration and resistance detonation two categories.

二、结构设计:Structural design

产品由芯件和壳体两部份组成,芯件是核心,是由两层超薄的不锈钢带,一条被压成波N形,另一条平面钢带则将它围绕圆心紧紧缠绕而成。从而构成无数个端面,是小三角形直通流道,而且在芯件内部有一个十字结构的支架(或在表面压上丫形架)借以增强芯件的牢靠性,避免芯件被点燃的介质所产生的爆炸压力冲散。介质从三角形狭道中通过,阻火器也正是通过它来阻止火焰在管道中的蔓延,其原理为“器壁效应”,就是火焰与器壁的碰撞进行能量转换,降低了温度。以此原理来设计三角形孔的高度阻止火焰的通过,再加上足够的流道长度来吸收火焰的热量,使其在芯件中熄灭,避免了气体在芯件的另一端被复燃的可能性。

Products from both the core and the housing portion of the core member is the core, consists of two layers of ultra-thin stainless steel strip, a pressure wave N-shaped, the other a flat strip around the center of the circle is tightly entwined. So as to constitute an unlimited number of end face, a small triangle straight-through flow and a cross bracket (or Y-shaped frame) on the surface of the pressure inside the core member so as to enhance the robustness of the core pieces to avoid the media core member is lit the the resulting explosion pressure to break up. The medium from triangle throat through, the arrester through it is also to prevent the spread of flame in the pipeline, and its principle is the "wall effect", is the flame and the walls of the collision energy conversion, reducing the temperature. This principle to design the height of the triangular hole to prevent the passage of the flame, plus sufficient flow path length to absorb the heat of the flame to extinguish it in the core member, may avoid the gas at the other end of the core member is reignition sex.

三、适用范围:Applicable scope

输送可燃性气体的管道上,包括火炬系统、油气回收系统、加热炉燃料气的管网上,气体净化通化系统、煤矿瓦斯排放系统及乙炔、氢气系统等。

Transport of flammable gas pipeline, including flare systems, vapor recovery systems, heating fuel gas pipe line, gas purification the Tonghua system, coal mine gas emissions systems and acetylene, hydrogen system.
