Device and method for avoiding explosion caused during process of filtering inflammable dust-like material

摘要

When an explosion is started in the crude gas area (9) it causes a pressure wave moving through the filter unit (8) to the refined gas area (1). It is guided into the relief device (2), opening a first relief panel (3) located at the processing side, enters the relief panel area (3), is guided via the side chamber (6) to a u-shaped manometer (7) and activates a system-separating and explosion-suppressing mechanism. If the mechanism fails a counter pressure is built up in the connection (5) to the relief panel chamber in order to change the difference in pressure, which also results in a system-separating and explosion-suppressing action.
