Nevtralizacija odpadnih mešanih anorganskih kislin z apneno suspenzijo v industrijskem mešalnem reaktorju

Štros, Alen (author), Plazl, Igor (mentor)

V magistrski nalogi je predstavljeno, kako lahko različni parametri mešanja vplivajo na celotno kakovost mešanja v procesu nevtralizacije v mehansko mešani posodi s pomočjo turbinskega mešala z nagnjenimi lopaticami. Prikazano je, kako lahko zasnova posode in mešala vpliva na učinkovitost mešanja, glede na različne končne izdelke, in na njihove končne lastnosti. Izvedene so bile simulacije, s katerimi smo pridobili grob pregled nad enofaznim mešanjem v ekscentrični mešani posodi s pomočjo turbinskega mešala. Predstavljenih je bilo nekaj predlogov, kako optimizirati postopek mešanja. Simulacije so bile narejene s pomočjo COMSOL®.

Abstract

This master’s thesis presents how different mixing parameters can affect the overall mixing quality in a neutralization process in a mechanically stirred vessel using a pitched blade turbine. It is shown how vessel and impeller design can influence mixing efficiency in various end products and their final properties. Simulations are performed to get a rough overview of a single phase mixing in an eccentric stirred vessel using a pitched blade downward turbine. Some suggestions are made on how a mixing process can be optimized. The simulations were performed with COMSOL®.
