Description

Technical Field

[0001] The utility model relates to the technical field of flameless explosion relief devices, in particular to a flameless explosion relief device. Background Art

[0002] A flameless explosion vent is a channel for discharging pressure or energy on a device or equipment box that may explode in order to avoid explosion. The metal filter assembly installed inside the existing explosion venting device filters the internal explosion dust when the metal dust in the powder drying container explodes to prevent the dust from being discharged to the outside. The explosion vent also prevents the flame from being exposed when the explosion occurs.

[0003] Existing flameless explosion vents are generally installed at the outlet end of the exhaust pipe of the device. General explosion vents will only install a separate exhaust port at the outlet of the pipe. Therefore, they must be disassembled for subsequent cleaning or maintenance. In order to avoid explosion, the equipment or device needs to be shut down. Moreover, because explosion venting itself is a rapid pressure relief in critical moments, a single exhaust port is bound to affect the pressure relief.
