Extinguishes explosion flames—No explosion flames can escape, ensuring a safe operating environment.2. Retains explosion dust—Captures process materials, eliminating potential harmful substances from entering the environment.3. Controls explosion pressure—Absorbs peak explosion pressure, protecting personnel and the surrounding environment from explosion pressure damage.4. Controls explosion temperature—Absorbs the explosion fireball, preventing a significant rise in ambient temperature.Pipeline Flame-Free Explosion Vent (Flame-Free Explosion Vent Valve) Product Features:Static activation pressure: 0.01 MPa.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 connections.Flange interfaces can be customized.Complies with EN16009 standard, passing standard tests.Offers 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: Blocks the explosion using an isolation valve to prevent flame propagation.Suppression: Detection devices identify sparks and trigger fire suppression systems to instantly extinguish flames, preventing explosions.Explosion vent panels are widely used in industries such as grain, metallurgy, chemicals, power, light industry, pharmaceuticals, tobacco, machining, and solid waste treatment. They are applied in equipment like cyclone separators, baghouse dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller mills, and buildings. They are mainly used in low-pressure,常温 environments requiring large venting areas, 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, installing such devices indoors is not permitted by safety regulations because it endangers nearby 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. more>

Product Description: A flameless explosion venting device is a safety apparatus designed to protect equipment and personnel by automatically shutting down equipment or pipelines in the event of an explosion or fire, preventing the spread of flames or expansion of the explosion. Its working principle involves detecting changes in gas pressure and temperature inside pipelines or equipment to determine the risk of explosion or fire. If a hazard is confirmed, it immediately closes the equipment or pipeline while releasing pressure to safeguard both the equipment and personnel.Flameless Explosion Vent Valve (Flameless Pressure Relief Valve)Brief Introduction:1. It consists of two parts: an explosion vent panel and a flame quenching module;2. Suitable for flameless venting of dust explosions in indoor equipment. It offers high venting efficiency and is cost-effective;3. Effectively blocks flames and heat, providing a safe environment for equipment, buildings, and personnel, while also collecting dust to reduce environmental pollution;4. When used in combination with an isolation valve, it not only prevents pressure waves and flames from propagating to upstream production areas but also mitigates secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static opening pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg·m/s, with effective venting area meeting explosion venting requirements;Product classification: Depending on the application, it can be divided into rectangular flameless explosion venting devices and curved flameless explosion venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spray painting, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Flameless Explosion Vent Valve (Flameless Pressure Relief Valve)Working Principle:The flameless venting device consists of two parts—an explosion vent panel and a flame quenching module. The explosion vent panel responds to rapid increases in deflagration pressure by immediately opening to reduce pressure. When the expanding fireball passes through the open vent panel, it is intercepted by the flame quenching module. The stainless steel precision mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and preventing its propagation, thereby avoiding secondary or multiple explosions. The flame quenching module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open vent panel.Simultaneously, pressure waves or noise generated by production equipment are significantly reduced. As flames pass through the mesh flame arrestor, heat exchange occurs between the arrestor and the flames, rapidly cooling the high-temperature flames, releasing pressure and smoke, while also reducing pressure waves or noise from production equipment.Application Fields:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, machining, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller grinding, buildings, and more.With increasingly stringent environmental inspections, safety has become a major concern. In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions.
