(Lviv Politechnic Publishing House, 2017-09-08) Atamaniuk, Volodymyr; Kindzera, Diana; Huzova, Iryna; Liuta, Oksana; Lviv Polytechnic National University
The results of experimental studies of the kinetics of filtration drying of disperse materials of different structural structure and dispersible composition are presented in the paper, as well as the dynamics of saturation of the waste heat agent with moisture during the filtration drying of materials at different height of layer of the last ones. On the basis of the generalization of research results, optimal parameters for the implementation of filtration drying were determined, and the economic effect from the introduction of filtration drying into production, per 1000 kg of dry material, was calculated.
Intensification of drying process during activated carbon regeneration
(Lviv Politechnic Publishing House, 2018-01-20) Atamanyuk, Volodymyr; Huzova, Iryna; Gnativ, Zoriana; Lviv Polytechnic National University
Досліджено тепломасообмінний процес під час регенерації активованого вугілля. Обґрунтовано механізм фільтраційного висушування активованого вугілля за умов однакової його температури з тепловим агентом. Згідно обґрунтованому механізму, тепловому балансу та критеріальних рівнянь встановлено час припинення подачі теплового агенту. Доведено, що енергії акумульованої частини висушеного шару активованого вугілля буде достатньо для довисушування шару до кінцевої вологості. Запропонований спосіб регенерації дає змогу зменшити кількість затраченої питомої енергії.
Reducing of energetic costs for drying process for candied pears production
(Lviv Polytechnic Publishing House, 2016) Atamanyuk, Volodymyr; Huzova, Iryna; Patrii, Nataliia; Lviv Polytechnic National University
According to calculations of the heat balance were calculated amounts of energy accumulated by pears layer and energy required to evaporate moisture. It was determined that reduce of energy costs for candied fruits drying is achieved by final drying at ambient temperature.
Research of the process of regeneration of activated carbon during filtration drying
(Видавництво Львівської політехніки, 2017-12-23) Atamanyuk, Volodymyr; Huzova, Iryna; Gnativ, Zoriana; Hrynkiv, Mykola; Bodnar, Mykola; Lviv Polytechnic National University
Heat-mass exchange processes during drying of regenerated activated carbon was to study and determine minimum height of heat-mass exchange zone and time of termination of hot heating agent supply based on criterion equations and heat balance calculations.
