Abstract
A gas-scrubber apparatus, including a chamber having an inlet means for receiving polluted gases to be scrubbed and having outlet means through which scrubbed gases are discharged, and heating elements for heating the chamber to maintain the polluted gases at predetermined temperature levels between the inlet means and the outlet means. The chamber includes a reaction zone for receiving a mixture of solid scrubbant materials for reacting with the polluted gases and a gas blower for directing the polluted gases to travel through the chamber to react with the scrubbant materials. At least one scrubber assembly is mounted in the reaction zone of the chamber having a baffle for collecting the polluted gases in the area adjacent the wall of the chamber. The scrubber assembly also includes thermo-convection pipes for transferring the collected polluted gases from the wall area towards the center of the chamber to maintain a substantially uniform heat distribution in a horizontal direction across the scrubber assembly. The chamber also maintains a vertical temperature gradient from the bottom to the top of the reaction zone of the chamber.
