Prantsuz O. Increase of ventilation exhaust purification efficiency with a whirlpool turbulent scrubber

The subject of investigation. Processes of gas flow cleaning from suspended particles in forward flow cyclones have been investigated. The purpose increase of purification efficiency for ventilation and process gases exhausted to atmosphere from industrial sources by development and introduction of efficient whirlpool turbulent scrubbers. The theoretical and practical results. Experimental studies on a laboratory model of the whirlpool turbulent scrubber were performed according to the plan of experiment, formulas found to determine hydraulic resistance of whirlpool turbulent scrubber, efficiency of dust removal from gas, efficiency of liquid drop catching, consumption of liquid circulating within the unit. Design of a whirlpool turbulent scrubber proposed and operation mode selected to provide for high efficiency of wet purification of ventilation exhaust gases (above 99,9%), high efficiency of drop catching (above 99%), low hydraulic resistance (up to 1500 Pa with liquid consumption 0,032 L per1m3 of the gas to be treated). Due to the liquid recirculation specific wetting makes as much as above 30 L per 1m3 of the gas to be treated. The novelty -new design and method of account a whirlpool turbulent scrubber. The level of implementation. The results of investigation carried out are introduced for cleaning of air at the Kremenchug tobacco factory and Novoivanovskiy sugar factory. The sphere of implementation - industry.
