Flameless venting device to prevent secondary dust explosions—flameless venting.
The flameless venting device consists of a flame-quenching template, a venting disc, an explosion-proof junction box, and a clamp. The venting disc is equipped with a signaling device that can be connected to a control box or alarm via the explosion-proof junction box, enabling it to interlock with fans or other equipment. The explosion-proof core is formed by connecting the housing and the top cover through square tubes, creating a flame-quenching module component. When the venting disc reacts to the rapidly accumulating deflagration pressure and opens to release this pressure, the forming fireball is intercepted by the flame-quenching module as it passes through the opened venting disc. A precision stainless steel mesh screen housed in a stainless steel frame serves as a three-dimensional flame-arresting element to extinguish the flame. The flame-quenching module effectively suppresses the flames generated by deflagration.

The flameless venting device consists of a flame suppression template, a venting disc, an explosion-proof junction box, and a clamp.The rupture disc is equipped with a signaling device and can be connected to a control box or alarm via an explosion-proof junction box, and it can also be interlocked with a fan or other equipment.The explosion-proof core is integrally formed by being connected to the housing and the top cover via square tubes, creating a flame-arresting module component. When the rupture disc reacts to the rapidly accumulating deflagration pressure and opens to release this pressure, the forming fireball is intercepted by the flame-arresting module as it passes through the opened rupture disc.A precision stainless steel mesh screen mounted in a stainless steel frame serves as a three-dimensional flame arrester to extinguish flames.The extinguishing module suppresses the flames and hot gases from deflagration, as well as combustible and non-combustible dust that is released when the explosion-proof door is opened.The 3D mesh screen design acts as a radiator, preventing explosions in the central section and absorbing the pressure waves and dust released during venting.Although the fireball from a dust explosion can easily reach temperatures as high as 1,000℃, the large surface area of the flame-suppression module allows for rapid cooling and helps keep the temperature below 100℃.This ensures that temperature fluctuations around the system are negligible. Thanks to its ability to extinguish flames, suppress dust, and precisely control pressure and temperature, the system can be used anywhere indoors where it’s necessary to prevent blast-overpressure effects.Detailed product description1. Extinguish explosion flames—no explosion flame can escape, ensuring a safe operating environment;2. Retention of explosive dust—capturing process materials and preventing potentially harmful substances from entering the environment;3. Control explosion pressure—absorb the peak of the explosion pressure to protect personnel and the surrounding environment from damage caused by the explosion pressure.4. Control the explosion temperature—absorb the explosion’s fireball to ensure that the surrounding environment’s temperature remains virtually unchanged.5. Effectively blocks flames and heat, providing a safe environment for equipment, buildings, and personnel on the move;6. Effectively collects dust without causing any environmental pollution;7. Made from stainless steel, designed for use in the food and pharmaceutical industries;8. A high-quality and reliable system design;9. Simple installation and maintenance-free operation;10. Exemption from high-cost building renovation expenses;11. Economically cost-effective solutions;12. Complies with EN16009 standard (Flameless explosion venting devices)Product Technical Specifications:
