The principle of operation of a plastic mist separator is similar to the principle of operation of a drop catcher. The fuel gas passes through the curved contour of the drop trap, and the output drops in the air are formed under the influence of inertia and gravity. The system consists of deffoger. It also includes a housing and flushing system. The flushing system consists of flushing tubes, fittings, frame, traverse, connections, mounts, seals, which are widely used in desulfurization systems.
