Depending on the results of the hazard and risk analysis, a number of proven precautions should be taken. They are divided into explosion prevention and explosion protection. Precautions should be taken to prevent explosive atmospheres and thereby reduce the possibility of explosion.
Precautions include reducing the effects of a possible explosion to a more moderate level so that the damage is not too severe. These include conventional ventilation via exploding discs, flameless ventilation, explosion isolation, and explosion suppression. This type of explosion check is a vital necessity in almost any installation.
In the event of an explosion, the vent protects the system by opening it. This relieves excess pressure in the container and triggers the explosion to the outside. Since practically no process is identical, there are many types of blast holes, differing in shape and material, as well as in temperature, pressure, and vacuum resistance.
Flameless ventilation is an inexpensive and efficient option. For now, let's look at the specific technology: The special mesh filters used in the Q-Box, Q-Ball, or Q-Rohr effectively cool all flames, prevent flames and pressure, and provide particle retention. The typical increases in pressure and noise are reduced to almost imperceptible, thus protecting people and machines.
However, explosion protection is intended to ensure that pressure and flame do not spread and all adjacent installation components are protected. A distinction is made between active and passive isolation systems.
In the event of an explosion, the valve closes by spraying the pressure front thereby effectively preventing the pressure and fire from spreading.
