Abstract
A flame front diverter element is designed to cause a minimal pressure drop under normal venting conditions when process vapors need to pass through the explosion protection system and to other equipment connected to the manifold system. In the event of a deflagration, the flame front diverter directs the high-speed pressure wave towards a bi-directional rupturable disc causing the rupturable disc to open thus creating an aspiration effect on the opposite bi-directional rupturable disc.
Claims8
Flame diverter element, comprising:
- an elongated channel having opposing first and second end portions and a rupturable disc in fluid communications with said elongated channel mounted to each of said opposing first and second end portions;
- and,
- first and second vapor flow channels disposed in said elongated channel, said first and second vapor flow channels each having an inlet and outlet, one of said inlet having a predetermined spacing from said rupturable disc at one of said opposing first and second end portions and one of said outlet having a predetermined spacing from the other end of said elongated channel, either of said first and second vapor flow channels being configured to receive process vapor from a flammable process and to form a primary flow path for process vapor propagation between said elongated channel and the other of said first and second vapor flow channels to a downstream process.
