DUST COLLECTION, HEAT- AND MASS EXCHANGE IN INTENSIVE-ACTION APPARATUS

The object of the investigation is new package swirl-type nozzles used in column apparatus in the processes of dust collection, heat- and mass exchange. The purpose is the development and investigations of a new swirl-type package nozzle for the processes of wet dust collection, heat- and mass exchange processes at thermal desorption of oxygen from water, the creation of methods of their design, as well as the determination of the criterium of estimating a possibility of recirculation of sprayed liquid at wet dust collection. A method of determining the efficiency of the dust collection in the apparatus furnished with the swirl-type package nozzle has been devised. A mathematical model, programs and algorithms for estimating the heat- and mass exchange at thermal desorption of oxygen from water have been developed, with the turbulent fluctuating in the vapour-gas medium and liquid in the apparatus fitted with the swirl-type original package nozzle taken into account. New high-efficient column apparatus for dust collection and thermal desorption of oxygen from water have been designed. The new column apparatus have been introduced at a number of plants of Poland.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
