Paradox Intellectual Properties: Flame Arrester Manufacturer

End-of-Line Venting System Protection

Integrated into vent outlets of chemical reactors and storage tanks, the disc prevents external ignition sources from entering flammable vapor spaces, enabling safe atmospheric release during filling or pressure fluctuations.

In-Line Deflagration Arrestance

Installed within piping systems conveying combustible gases or solvents, the element arrests flame fronts resulting from accidental ignition, protecting downstream equipment, including condensers, compressors, and scrubbers.

Vapor Control Unit Safety Core

Functions as the primary isolation barrier within vapor recovery units and incineration systems, preventing flashback from thermal oxidizers into mixing zones containing volatile organic compounds.

Process Analyzer Shelter Safety

Utilized in sample lines and vent headers leading to gas analyzers in hazardous areas, the disc suppresses potential flames generated by electrical components or static discharge.

Fuel Gas Train Safety Isolation

Embedded in supply lines to industrial burners and boilers, the sintered metal disc provides fail-safe protection against upstream pressure surge-induced explosions or reverse flame propagation.

The 0.2μm SS316L Porous Filter Disc functions as a passive safety device based on the principle of flame quenching through heat absorption and flow interruption. Its sintered porous structure consists of a labyrinth of narrow, interconnected micro-channels that dissipate combustion energy and terminate free-radical chain reactions.

Working Process:

Flame Front Engagement

Upon deflagration exposure, the flame front enters the porous matrix, where the micro-channels divide the combustion wave into minute segments.

Heat Dissipation

The high thermal conductivity of the sintered SS316L material and its large surface area rapidly absorb and transfer heat away from the flame zone, reducing the temperature below the auto-ignition point.

Radical Termination

The narrow, tortuous passages quench active free radicals essential for sustaining combustion by disrupting their collision frequency and energy transfer.

Flow Restriction & Pressure Drop

The porous structure induces a significant pressure drop across the disc, slowing the incoming flammable mixture to a velocity lower than the burning rate, preventing flame passage.

Post-event Integrity

Following a flame arrestment event, the rigid metallic structure maintains its dimensional and functional integrity, allowing continued operation without replacement. The disc remains ready for subsequent events without performance degradation.
