Brief introduction to the circular flameless explosion relief device:
Flameless explosion relief device is an important safety device used to prevent explosion accidents, which can be used to prevent the explosion of gas or dust under specific conditions. It can detect the concentration of explosive gas or dust, and take measures in time to prevent the occurrence of explosive. Flameless explosion relief devices are widely used in petroleum, chemical, pharmaceutical, grain and other industries, and play an important role in safety protection in industrial production.
Composition of flameless explosion relief device:
The flameless explosion relief device is mainly composed of three parts: fire resistance element, pressure relief element and shell.
1. Fire resistance element
Flame arresting element is the core part of flameless explosion venting device, which mainly plays the role of preventing flame propagation. It is usually composed of multiple layers Metal mesh Or multi-layer metal plates, and the aperture of these metal nets or metal plates is below the micron level, which can effectively prevent the spread of flame. At the same time, the flame arresting element also has certain structural strength, which can effectively withstand the impact of detonation shock wave.
2. Pressure relief element
Pressure relief element is another important part of flameless explosion relief device, which mainly plays the role of pressure release. It is usually composed of diaphragm, metal mesh or metal plate. When the explosion shock wave acts on the pressure relief element, it can quickly release the pressure, so as to avoid equipment damage or explosion caused by excessive internal pressure of the equipment.
3. Housing
The shell of flameless explosion relief device is usually made of steel or cast iron, which mainly protects the internal components. At the same time, the shell also has certain structural strength, which can effectively withstand the impact of detonation shock waves.
Principle:
The principle of flameless explosion relief device is mainly based on the function of fire resistance elements and pressure relief elements. When the explosion occurs, the explosion shock wave will act on the fire resistance element and the pressure relief element at the same time. The flame arresting element can quickly isolate the flame in a small range to prevent the flame from spreading around; The pressure relief element can quickly release the explosion shock wave, thus reducing the internal pressure of the equipment and avoiding equipment damage or explosion.
At the same time, the flameless explosion relief device also has a certain silencing effect. The internal fire resistance elements and pressure relief elements can convert the explosion shock wave into heat and pressure, thus avoiding the explosion shock wave directly acting on the surrounding equipment and buildings, which plays a role in noise reduction.
Classification of Circular Flameless Detonator Devices ： According to different operating conditions, it can be divided into circular flameless explosion venting device and rectangular cargo flame explosion venting device.
