Multi-stage wet exhaust gas treatment chamber with interspersed air ducts and venturi cluster, static mixing on the recircuit line

Abstract

The useful solution refers to a wet exhaust gas treatment chamber (100) with at least three inclined flow guide plates (120). Each plate has a free edge (122) away from the opposite side wall to create a gas guide slot (121); the slots of adjacent layers are alternate on both sides, forcing the gas flow to change direction repeatedly. The nozzle (130) at each layer is oriented so that the spray area (131) both wets the top surface of the plate and cuts through the slot, thereby allowing the solution to flow to the free edge and fall as a solution curtain at the point where the gas flow must pass through. The solution is circulated from the tank (170) through the pump (141), Venturi type suction unit (150), static mixer (151) and common distribution manifold (144), then branched to the nozzles. The gas after the contact stages passes through the droplet separator (160) before exiting through the gas outlet (112).
