DRY SPRAY COLUMN AND METHOD OF COOLING, WETTING, AND/OR CLEANING GAS

摘要

FIELD: chemical engineering. SUBSTANCE: dry spray column excluding drain water formation contains upper part provided with gas-admission opening; expanded part gradually broadening downward from the upper part; and spray nozzles fastened to column expanded part or to column part immediately behind the expanded part in direction of stream to spray water and/or absorbing solution thereby cooling or wetting gas and/or removing hazardous component from gas. Gas-distribution device is disposed either in expanded part or near it before spray nozzles in direction of stream to provide greater descending constituent of gas stream velocity in peripheral part of column with sprayer than in its central part. This circumstance prevents collision of sprayed liquid drops with inner part of column. EFFECT: excluded drain water formation.
