阻火器系列 Flame Arrester

阻火器描述

管道阻火器是适用于石化、化工、轻工业等行业的可燃气体输送过程中的安全装置。我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 safety devices applicable to the petrochemical, chemical industry, light industry and other industries combustible gas transportation process. I plant manufacturing Pipeline Fire is made after a rigorous the flame arrester theory design and precision processing machinery and equipment dedicated. Resistance deflagration and resistance detonation two categories can be divided according to fire resistance and fire retardant grade.

结构设计 Structural Design

产品由芯件和壳体两部分组成,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Y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”,就是火焰雨器壁的碰撞进行能量转换,降低了温度。从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 offered by the two parts of the core member and the housing, the core member is a core, ultra-thin stainless steel band composed of two layers, one being pressed into a wave-N-shaped, the other it is a flat strip tightly entwined around the center. Numerous end face so as to constitute a small triangle straight through the flow channel, and the core pieces of the internal structure of a cross bracket (or in the surface pressure on the Y-shaped frame) so as to enhance the robustness of the core parts, to avoid the media are core pieces are lit the explosion generated pressure to break up. Media through the narrow channel from the triangle, the flame arrester is precisely to prevent the spread of flame in the pipeline through which the principle of the "wall effect" Rain of Fire wall collision energy conversion, lower the temperature. From this principle in the design of the height of the triangle hole to prevent the passage of flame. Flow channel length plus enough to absorb the heat of the flame to extinguish it in the core member, to avoid the possibility of the gas at the other end of the core member is recrudescence.

适用范围 Applicability

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。

Pipeline transporting flammable gas flare systems, vapor recovery system, furnace fuel gas pipe-line, the gas purification the Tonghua system, coal mine gas drainage system and acetylene, hydrogen gas system.

阻火器类别 Flame Arrester Category

\

概述:阻火器是安装在石油、化工、化纤储罐顶上,与呼吸阀、呼吸人孔、通气孔配套使用的安全产品。其功能能为允许气体通过,对火焰起到阻止、窒息的作用。

Overview: The flame arrester is installed in the petroleum, chemical industry, chemical fiber tank top with breathing valve, breathing manholes, vent supporting the use of security products. Its function is to allow gas through play to prevent the flame, the role of suffocation.

我厂生产的阻火器采用不锈钢“N”形、双层波纹带为阻火芯件,壳体材料可根据贮存介质的不同,有铝合金、碳钢和各种牌号的不锈钢。其结构有中石化北京设计院设计,科学合理,造型美观。产品曾多次经公安部天津消防科学所测试合格,并于1999年通过“科学技术成果”鉴定【(99)京设院鉴字02号】。

I plant the production of stainless steel flame arrestor "N"-shaped, double corrugated with flame arrester core pieces, shell material, depending on the storage medium, aluminum, carbon steel and various grades of stainless steel. Sinopec Beijing Design Institute structure, scientific and reasonable, attractive appearance. Products have repeatedly tested by the Ministry of Public Security, Tianjin Fire Science qualified and identified through scientific and technological achievements in [(99) the present,a court 02].

安装与维护 Installation And Maintenance

管道阻火器与管路连接可水平安装也可垂直安装。定期检查,一旦发现堵塞,应用高压蒸汽、压缩空气或有机溶剂清洗,如发现芯件机械性损坏或介质腐蚀后,应立即更换。

The Pipeline Fire and piping connections can be installed horizontally can also be mounted vertically. Periodic inspection, Once clogged, the application of high-pressure steam, compressed air, or organic solvent cleaning, such as the discovery of the core pieces of mechanical damage or corrosion medium, should be replaced immediately.
