Explosion protection is intended to protect personnel and surrounding machinery. Explosion isolation involves "blocking" the explosion through the pipeline process. The goal here is to stop it from traveling any further.
An explosion can continue to gain momentum and create secondary explosions and fires. Despite the release or suppression of the explosion, the dust explosion can still move backward. This is carried from the process vessel to the rest of the process zone via inlet pipes and associated equipment. You can hire professionals to install an explosion isolation valve.
You can also use explosion-proof insulation on dust collectors, process vessels, or other equipment. In this case, it is used together with the connection pipe and adhering to the installation distance to the tank.
Dust collector insulation
The dust collector holds a large amount of dust. If this combustible dust spreads into the air and ignites, the result is catastrophic, so the dust collector must be isolated. Explosion ventilation then avoids this risk.
However, in some cases, pressure waves and dangerous flames can propagate back through the connecting line. This requires the use of a blast isolation valve, also known as a non-return valve, flap valve, or barrier valve.
In the event of an explosion, the pressure surge initially forces the valve to close, blocking further distribution of the flame through the process line connecting process ductwork, thereby isolating the collector from the explosion.
