The ZHQ-I gravel flame arrester is a flame arrestor safety device that uses gravel (quartz sand, ceramic balls, or metal balls) as the flame arresting medium. It is installed on tank breather piping, vent systems, or flammable gas pipelines. The interior is filled with a layer of gravel of a certain particle size, and the small gaps between the gravel particles form flame arresting channels. When flame passes through, heat is rapidly absorbed and dissipated, extinguishing the flame, thereby preventing external flame propagation into the tank or downstream equipment. This flame arrester features a simple structure, high corrosion resistance, and large flow capacity. Its core purpose is to provide reliable flame arrestor protection for breather valves and vent pipes in petrochemical storage tanks, oil depots, gas stations, etc., especially suitable for applications with particulate matter or easily polymerized media to prevent clogging of the gravel channels.

1. Gravel flame arresting medium: Filled with gravel, quartz sand, ceramic balls, or metal balls; the gaps between gravel particles form flame arresting channels, providing high quenching efficiency with low medium cost and easy replacement.

2. Large flow area, low pressure drop: High overall porosity of the gravel layer minimizes gas flow resistance without affecting normal tank breathing capacity.

3. Strong anti-clogging ability: Insensitive to small amounts of particulates or polymers in the gas stream; gravel gaps are not easily completely blocked, suitable for dirty or fouling-prone applications.

4. High temperature impact resistance: Gravel packing withstands short-term high-temperature flame impact without sintering or deformation, ensuring stable flame arresting performance.

5. Good corrosion resistance: Housing available in carbon steel, stainless steel, or aluminum alloy; gravel is chemically stable, adapting to various corrosive environments.

6. Simple structure, easy maintenance: No complex disassembly required; end cover can be opened to remove, clean, or replace gravel packing, resulting in low maintenance cost.

7. Flexible installation: Standard flange connections allow horizontal or vertical installation, directly connecting to breather valves and piping.

8. Code compliant: Designed and manufactured according to relevant flame arrester standards (e.g., GB 5908), meeting fire protection requirements for petrochemical tank farms.
