ABSTRACT:
A multi-flash evaporator having modular vertical cyclone chambers designed to generate a paraboloid of revolution providing an extended surface area for release of flashed vapors and attaining equilibrium. With multiple stages, the system incorporates deep loop seals to prevent blowby between stages at all levels of capacity and employs a vapor lift system to permit low pressure differentials between stages at high vacuum. The cyclone chambers employ an intermediate tangential inlet whereby the flashing vapors propel the liquid at higher velocities to generate a deeper paraboloid of revolution and centrifugally separate the heavier liquid from the flashing vapor. An anti-creep ring is interdisposed at the top of the cyclone to prevent the liquid from entering a mesh so only vapor impinges on the mesh and passes to the heat recovery condensers embodying a bayonet augmented tube heat exchanger.
