Abstract
Instalatie de producerea bioxidului de titan, conform inventiei, permite reducerea diferentei de presiune dintre orificiul de intrare si orificiul de iesire din dispozitivul de alimentare si cuprinde niste dispozitive de admisie a materialului inert sub forma de particule în gazul purtator, continînd un dispozitiv mecanic de alimentare prevazut cu un orificiu de admisie pentru materialul inert sub forma de particule, asociat cu o conducta de admisie si un orificiu de evacuare pentru materialul inert sub forma de particule, asociat cu o conducta de evacuare si sisteme de conducte pentru furnizarea fluxului de gaz purtator si pentru stabilirea unui flux de gaz purtator în conducta de evacuare a dispozitivului de alimentare, prin aceasta antrenînd materialul inert sub forma de particule si dispozitive de reducere a diferentelor de presiune între orificiul de admisie al sistemului de alimentare si conducta de evacuare a acestuia, la locul în care materialul inert este introdus în gazul purtator. Modul de obtinere a bioxidului de titan prin oxidarea în forma de vapori a tetraclorurii de titan într-un reactor la o temperatura ridicata, materialul inert sub forma de particule fiind antrenat într-un gaz purtator ce este trecut prin reactor si/sau sistem de tevi folosite în procedeu pentru a reduce sau a preveni formarea de cruste, în interiorul suprafetelor acestora, face ca materialul inert sub forma de particule sa fie alimentat în gazul purtator printr-un dispozitiv mecanic de alimentare, iar diferenta de presiune obtinuta în orice moment între alimentarea materialului inert sub forma de particule la dispozitivul mecanic de alimentare si gazul
