SCRUBBER-EXHAUST GAS CONDITIONER

摘要

A conditioner for cooling and cleaning hot exhaust gas containing particulates has an enclosure partially filled with liquid and a gas conditioning means positioned within the enclosure. Hot exhaust gas entering the conditioning means passes through a liquid induction portion submerged in the liquid to introduce a portion of the liquid into the hot gas stream within the gas conditioner means to form a gas-liquid mixture. The hot exhaust gas-liquid mixture then flows through a contact portion of the conditioning means in which cooling of the hot exhaust gas takes place through vaporization of at least a portion of the liquid. The cooled exhaust gas-liquid mixture is then passed through a separator portion of the conditioning means in which the direction of the flow of the cooled exhaust gas-liquid mixture is changed. Separation of the cooled exhaust gas from at least a portion of the liquid and particulates occurs through a centrifugal action of the mixture within the separator portion of the conditioning means. The liquid and particulates removed from the cooled exhaust gas return to the pool of liquid within the enclosure. The cleaned and cooled exhaust gas impinges on a barrier type separator to remove additional liquid entrained in the cooled exhaust gas. The cooled exhaust gas then passes through an outlet opening in the enclosure to the atmosphere.
