Aluminum alloy storage tank flame arrester model: SCZ150-6

aluminum alloytankflame arresterIt is a safety product installed on the top of petroleum, chemical, and synthetic fiber storage tanks, used in conjunction with breathing valves, breathing manholes, and ventilation holes. Its function is to allow gas to pass through,

Plays a role in preventing and suffocating flames.The flame arrester produced by Nanshi adopts stainless steel "N" - shaped, double-layer corrugated tape as the flame arrester core, and the shell material can be aluminum alloy according to different storage media

Gold, carbon steel, and various grades of stainless steel. Its structure was designed by Sinopec Beijing Design Institute, scientifically reasonable, and manufacturedBeautiful appearance.

aluminum alloytankflame arresterstructural designThe product consists of two parts: the core and the shell. The core is made up of two layers of ultra-thin stainless steel strips, one pressed into a wavy N shape and the other flat

The steel strip is tightly wrapped around the center of the circle. Thus constituting nothingnumberThe end face is a small triangular straight channel, and there is a cross shaped support structure inside the core (or pressed on the surface)

The Y-shaped frame is used to enhance the reliability of the core components and prevent the explosive pressure generated by the ignited medium from dissipating. Medium narrows from a trianglePassing through the path, the flame arrester also uses it to prevent it

The spread of flames in pipelines is based on the "wall effect", where the collision between the flame and the wall converts energy and reduces temperature. This principle is used to design the height of triangular holes to prevent fire

The Flame PassBy adding sufficient channel length to absorb the heat of the flame, it can be extinguished in the core, avoiding the possibility of gas reigniting at the other end of the core.

aluminum alloyTank flame arresterworking principle：

flame arresterIt is designed and manufactured based on the principle that flames extinguish due to heat loss when passing through narrow pores of a thermal conductor. The function is to prevent external flames from entering equipment, pipelines containing gas, or

Stop the spread of flames between equipment and pipelines. Mainly divided into heat transfer workUsing the wall effect of the device.

Heat transfer function: One of the necessary conditions for combustion is to reach a certain temperature, which is the ignition point. Below the ignition point, the combustion will stop. According to this principle, as long as the temperature of the burning substance is controlled

Lowering it below its ignition point can prevent the spread of flames.When the flame passes through many small channels of the flame retardant element, it will turn into several small flames. Design the flame arrester element inside the storage tank flame arrester

When assembling, try to expand the contact area between the small flame and the channel wall as much as possible, enhance heat transfer, and lower the flame temperature below the ignition point,Thereby preventing the spread of flames.

Wall effect: Combustion is not a direct reaction between molecules, but is stimulated by external energy, which breaks the molecular bonds and produces activated molecules. The activated molecules then split into short-lived but lively free radicals,

Free radicals collide with other molecules to generate new products, whileIt also generates new free radicals that continue to react with other molecules. When the combustible gas passes through the narrow channel of the flame retardant element, free radicals

The probability of collision with the channel wall increases, and the number of free radicals participating in the reaction decreases. When the channel of the explosion-proof flame arrester is narrow to a certain extentAt this time, collisions between free radicals and channel walls dominate, due to the rapid number of free radicals

Drama reduction,The reaction cannot continue,That is to say, the combustion reaction cannot continue to propagate through the flame arrester.
