Apparatus for cleansing flue gases
Abstract
Abstract THE INVENTION RELATES TO AN APPARATUS FOR PURIFYING THE GASES TO REMOVE SULPUR DIOXIDE. THE APPARATUS COMPRISES A CONTAINER FOR A BODY OF TREATMENT LIQUID AND IS PROVIDED WITH A GAS INLET SO ARRANGED THAT THE GAS IS CAUSED TO FLOW SUBSTANTIALLY AT RIGHT ANGLES TO THE SURFACE OF THE LIQUID THEREIN. A TREATMENT PASSAGE EXTENDS SUBSTANTIALLY VERTICALLY UPWARDS FROM THE LIQUID SURFACE IN THE CONTAINER, SO THAT THE GAS AFTER CONTACT WITH THE LIQUID FLOWS SUBSTANTIALLY LINEARLY THERETHROUGH ENTRAINING DROP- LETS OF LIQUID. THE CONTAINER COMMUNICATES BELOW THE LIQUID LEVEL WITH AN EQUALIZING TANK HAVING MEANS FOR INTRODUCING ALKALI THEREINTO TO MAILNTAIN THE TREATMENT LIQUID AT A SUITABLE ALKALINITYAND WITH MEANS FOR INTRODUCING FRESH WATER. THE EQUALIZING TANK ALSO HAS MEANS TO MAINTAIN THE LIQUID LEVEL THEREIN CONSTANT WHEREBY THE LIQUID LEVEL IN THE TREATMENT CONTAINER ADJUSTS AUTOMATICALLY TO VARIATIONS IN THE RATE OF GAS SUPPLIED THERETO.
