PROCESS AND APPARATUS FOR CLEANING SOLIDS LADEN GAS

摘要

A solids-laden gas is cleaned by introducing a condensing fluid in the gas to saturate the gas and allowing liquid to condense on the solids to form enlarged particles. Liquid separated from the gas with enlarged particles is then atomized in the gas to form agglomerates of liquid and enlarged particles, whereafter the formed agglomerates are separated from the gas. An apparatus for carrying out this process is also described, the apparatus being characterized by a first stage in which means are provided for enlarging solids in a solids-laden gas flow by contact with a condensing fluid, separation of liquid from the gas flow, and a second stage in which means are provided for introducing the separated liquid into the gas flow in a venturi-shaped gas passage member.
