Dust collector explosion vent (pipeline explosion vent)

Flame-free explosion venting consists of two parts:
1) Explosion vent panel;
2) Flame quenching template;

Product functions:

1. Extinguish explosion flames—No explosion flames can escape, ensuring a safe operating environment.
2. Retain explosion dust—Captures process materials, eliminating potential harmful substances from entering the environment.
3. Control explosion pressure—Absorbs peak explosion pressure, protecting personnel and the surrounding environment from explosion pressure damage.
4. Control explosion temperature—Absorbs explosion fireballs, preventing a significant rise in ambient temperature.

Dust Collector Explosion Vent (Pipeline Explosion Vent) Product Features:
Static activation pressure: 0.01MPa.
Material: Carbon steel/304 stainless steel.
No special maintenance required.
Online maintenance structure available, allowing replacement of explosion vent panels and cleaning of flame arrestor elements without disassembling the interface.
Flange interfaces can be customized.
Complies with EN16009 standard, passing standard tests.
Provides various forms of flame-free venting structures to meet different working condition requirements.
No open flame design, effectively preventing significant losses caused by secondary dust explosions.
Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors, etc.

There are three main methods for dust explosion protection: venting, isolation, and suppression.
Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.
Isolation: Prevents flame propagation by using an isolation valve to block the explosion.
Suppression: Detects sparks with a detection device, then activates a fire extinguishing system to instantly suppress the fire and prevent explosion.

Explosion vent panels are widely used in industries such as grain, metallurgy, chemical, power, light industry, pharmaceuticals, tobacco, machining, and solid waste treatment. They are applied in equipment like cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying, rod or ball mills, bucket elevators, dryers and ovens, roller grinding, and buildings. They are mainly used in low-pressure,常温, and large venting area working environments such as dust collectors, dust collection pipelines, and elevators.

In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, such installations on indoor equipment are not permitted by safety regulations because they endanger surrounding personnel and equipment. The pressure waves and flames from explosions may cause secondary or multiple explosions, posing greater risks. Therefore, relying solely on explosion vent panels for dust collectors is not reliable. We recommend using flame-free explosion venting + isolation technology (a more economical solution) or suppression + isolation technology to ensure production safety.
