Abstract
Il dispositivo per il ricupero di un solvente (20) da una miscela (21) di acqua-solvente presenta un contenitore (22) con evaporatore (30) e condensatore (100) disposti in esso, i quali sono collegati tra loro attraverso un circuito di raffreddamento (1) comune con un compressore (2) inserito in esso.Inoltre il dispositivo nel contenitore (22) ha almeno un ugello (23) associato all'evaporatore (30) e spruzzante, attraverso una conduttura (25) con pompa di convogliamento (24) inserita, la miscela (21) di acqua-solvente sull'evaporatore (30); in relazione a ciò la miscela (21) di acqua-solvente viene trasformata sull'evaporatore (30) molto caldo in una miscela nebulizzata, poi le molecole di solvente vengono separate dalle molecole dell'acqua e le molecole di solvente ascendenti condensano sul condensatore
