PRESSURE RELIEF DEVICE, MODULAR PRESSURE RELIEF UNIT AND FIRE PROTECTION DEVICE

摘要

The present invention relates to a pressure relief device for explosive gases, which includes a conversion (12) to a releasable in the event of an explosion discharge (11), wherein in the enclosure (12) passage areas are provided with gasdurchlässigem material (8,9,10) through which in the event of an explosion, the explosion gases (13) are conducted into the atmosphere (14). The pressure relief device is characterized in that the enclosure (12) contains at least one gas-permeable pressure relief module (1) which has an outer gas-permeable housing part (2) in which at least two flow-through flame trap chambers (3, 4, 5) are arranged. In the flame trap chambers (3, 4, 5) steel wool fillings (8, 9, 10) or gas-permeable materials (58, 59, 60) arranged with steel wool fibers (15, 16, 17) or fibers (55, 56, 57) of different diameters.;Furthermore, the present invention relates to a modular pressure relief unit comprising at least two gas-permeable pressure relief modules (1) in a housing component.;Finally, a fire protection device is described which is characterized in that an enclosure (112) has at least one gas-permeable fire protection module (101) with at least two burn-through fire barriers (103, 104, 105) which are provided with fibers (55, 56, 57) of different diameters are filled.
