In the process of industrial production, once the dust remover and other equipment burst or overpressure occurs, the explosion relief product can timely and effectively release the overpressure generated by the superposition of explosion shock waves. When the pressure rises to the static pressure opening pressure of the explosion relief plate, the passive explosion relief plate can timely open and release the pressure to prevent * * * pressure from exceeding the structural strength limit of dust remover and other equipment, Protect the safety of equipment and production personnel, and reduce the severity of explosion accident consequences.
Flameless venting consists of two parts:
1) Bursting disc;
2) Flame extinguishing formwork;
Introduction to dust flameless explosion relief device:
Flameless explosion relief device:
The safety pressure relief device set for the indoor dust removal system is suitable for dust collectors, bucket type Hoist , dryer, cyclone separator, dust collector and other equipment and facilities. The device consists of flame barrier material, low carbon steel shell, etc.
working principle:
This device is used together with the explosion relief plate. When the dust of the protected equipment explodes, the explosion relief plate will open due to the rapidly rising pressure, and the flame barrier material will quickly absorb the flame, burning or unburned dust and gas, effectively preventing the flame from blowing out, safely releasing the pressure and filtered flue gas, and avoiding dust explosion or fire accidents caused by the spread of the flame.
Four safety functions of flameless relief device:
1. Flame capture
No flame can escape, provide a good operating environment, and eliminate the hazards of external secondary ignition and its possible continuous explosion to equipment 2. Dust retention
Capture processing substances and eliminate potential harmful substances entering the environment
3. Eliminate high voltage
Buffer the peak pressure of explosion, protect personnel and the surrounding environment, including buildings, from the pressure threat of explosion
4. Temperature control
Absorb fireballs, but the surrounding temperature environment hardly increases
Function of dust flameless explosion relief device:
Flameless discharge device is mainly used for protection of indoor dust explosion other Operation cost, simple installation, no need to install pressure relief conduit, it is composed of explosion relief device and fire resistance element. When the equipment cannot withstand the fireball from deflagration The Conduit When discharging, flameless discharge technology is another option of passive protection system. Flame capture, no flame can escape, provide a safe operating environment, eliminate the hazards of external secondary ignition and its possible continuous explosion to equipment, buffer the peak explosion pressure to protect personnel and the surrounding environment, including buildings, from the pressure hazards of explosion, dust retention, capture processing materials, eliminate potential harmful substances, and enter the environment.
