The flameless explosion-proof device is mainly used for indoor dust explosion protection, with no other operating costs, easy installation, and no need to install pressure relief pipes. Explosion relief device is a processing equipment designed specifically for dust explosion prevention and pressure relief. This safety device can be applied indoors to extinguish flames, retain dust, control pressure and temperature, and meet the requirement of not directly releasing the impact of explosions indoors, ensuring that flames are not spread and causing secondary or multiple explosions.

Introduction to flameless explosion-proof device with testing report:

1. No open flame design can effectively prevent huge losses caused by secondary explosion of dust

2. Customized processing according to customer requirements

3. Easy installation, simple hinge design and maintenance

4. Capture processed substances and eliminate potential harmful substances from entering the environment

5. Applicable equipment: dust collector, bucket elevator, drying equipment, cyclone separator, dust collector

Working Principle:

When the flame passes through the mesh flame retardant element, the flame retardant element exchanges heat with the flame, quickly cooling the high-temperature flame, releasing pressure and smoke, ensuring that the flame is not spread, thereby causing secondary or multiple explosions. At the same time, the pressure waves or noise generated by the production equipment will also be reduced. In industrial production, the combination of flameless venting devices and explosion-proof valves not only effectively prevents pressure waves and flames from spreading to the production site of upstream workshops, but also suppresses the occurrence of secondary explosion accidents, reduces property losses, and protects personnel safety.

Provide various forms of flameless venting structures to meet the needs of different working conditions.

The flameless explosion-proof device with a detection report consists of two parts: the explosion-proof board and the fire extinguishing module.

The explosion-proof plate responds to the rapid increase in detonation pressure and immediately opens to reduce the pressure. When the expanding fireball passes through the opened explosion-proof plate, it is intercepted by the fire extinguishing module. Stainless steel precision mesh supported by a frame plays a three-dimensional flame capture role, extinguishing flames and ensuring that they are not spread, thereby causing secondary or multiple explosions. The fire extinguishing module eliminates the flames of detonation, reduces the temperature of hot gases, and captures the combustion and unburned dust passing through the opened explosion-proof plate. At the same time, the pressure waves or noise generated by production equipment will also be reduced to a very small level.

Structural composition:

Smoke free release devices are mainly used for indoor dust explosion protection, with no other operating costs, easy installation, and no need to install pressure relief pipes. It consists of an explosion-proof plate, a clamping base, and an explosion-proof box.

Product advantages:
1. Extinguishing Explosion Flames - No explosion flame can escape, and the explosion-proof device effectively prevents flames and heat, providing a safe place for equipment, buildings, and mobile personnel.
2. Retain explosion dust - Capture process materials and eliminate potential harmful substances from entering the environment.
3. Control explosion pressure - absorb peak explosion pressure, protect personnel and surrounding environment from damage caused by explosion pressure.
4. Control the explosion temperature - absorb the explosion fireball, so that the surrounding environment temperature hardly rises.
5. Stainless steel design, suitable for the food and pharmaceutical industries;
6. We can provide an online repair structure, which allows for the replacement of explosion-proof discs and the cleaning of fire-resistant components without the need to disassemble the interface.

Used to protect personnel and equipment from flames and dust damage. During an explosion, flames and dust are emitted into the device. The flame generated by the explosion will be extinguished because it passes through several layers of heat absorbing stainless steel mesh, while the dust barrier captures the vast majority of particles. This enables flameless venting devices to be used indoors or in situations where the explosion propagation path poses a danger to personnel, also known as powder flame arresters.

In today's increasingly strict environmental inspections, safety has attracted more and more attention. In the past, we often used to install a venting plate on the dust collector to release the overpressure caused by dust storms. However, installing indoor equipment in this way is not permitted by the safety supervision department, as it can endanger surrounding personnel and equipment. The pressure waves and flames generated by explosive explosions may cause secondary or multiple explosions, posing greater risks. So using explosion-proof plates alone is unreliable for dust collectors. Therefore, we recommend using flameless venting and isolation technology (which is more economical) or explosion suppression and isolation technology to protect production safety.

Dust explosion is accompanied by strong shock waves and flames. Due to the equipment's lack of compressive strength, it will be damaged when an explosion occurs, resulting in the risk of secondary or multiple explosions. So we are required to pay attention to dust explosion protection.

There are three main ways to prevent dust explosions: explosion venting, explosion isolation, and explosion suppression

Explosion relief: By using a pressure relief device to release the explosion in advance, the equipment is protected from damage.

Explosion proof: A type of explosion-proof valve is used to block explosions and prevent flames from spreading.

Explosion suppression: Firstly, the detection device detects the initial spark formed, and then feedback activates the fire extinguishing device to instantly extinguish the fire and prevent the occurrence of an explosion.
