Working principle: flameless explosion relief device consists of flame extinguishing template, explosion relief plate, explosion-proof junction box and holder. The explosion relief plate is equipped with a signal device, which can be connected with the control box or alarm through the explosion-proof junction box, and linked with the fan or other equipment.

The explosion-proof core is connected by the shell and the upper cover through a square tube to form an extinction module component. When the bursting disc reacts to the rapidly accumulated deflagration pressure and opens to release the pressure, as the forming fireball passes through the opened bursting disc, it is intercepted by the extinction module. The stainless steel precision mesh screen installed in the stainless steel frame is used as a three-dimensional flame arrester to extinguish the flame. The extinguishing module contains deflagration flame and hot gas, as well as combustion and unburned dust by opening the explosion-proof door. The three-dimensional mesh screen design can act as a radiator to prevent the explosion in the middle part and absorb the pressure wave and dust released by the venting. Although the fireball temperature of dust explosion can easily reach 1000 ° C, the large surface area of the extinguishing module can be cooled quickly and kept below 100 ° C. This makes the temperature change around the system negligible. Due to the ability to extinguish the flame, contain dust and control pressure and temperature, the system can be used in any place in the room where explosion discharge impact needs to be avoided.

Safety function of flameless explosion relief device:

1. Put out the explosion flame - any explosion flame cannot escape, providing a safe operating environment.

2. Retention of explosive dust - capture process materials to eliminate potential harmful substances into the environment.

3. Control explosion pressure - absorb the peak value of explosion pressure, protect personnel and surrounding environment from explosion pressure damage.

4. Control the explosion temperature - absorb the explosion fireball, so that the ambient temperature is almost not increased.
