20.500.12556/RUL-130355 Čiščenje s suhim ledom CO2 snow cleaning Zaključno delo obravnava teoretične osnove in principe delovanja čiščenja s suhim ledom. Predstavljene so termodinamske lastnosti, mehanizmi čiščenja, sestavni deli opreme, procesni parametri in aplikacije. V delu smo analizirali delovanje šobe, ki je ključni sestavni del procesa. V programu NX-12 smo izdelali 3D model šobe, ki smo jo natisnili s 3D tiskalnikom in preizkusili. Med seboj smo primerjali rezultate delovanja šobe pri različnih vrednostih pretoka CO2-ja in zraka. Ugotovili smo, pri katerih vhodnih parametrih šoba deluje najbolje, in pojasnili, kako bi njeno delovanje lahko izboljšali. This work discusses the theoretical foundations and principles of CO2 snow cleaning. Thermodynamic properties, cleaning mechanisms, equipment components, process parameters and applications are presented. In this work, we analyzed the operation of the nozzle, which is a key component of the process. In the NX-12 program, we made a 3D model of the nozzle, which we printed with a 3D printer and tested. We compared the results of the nozzle operation at different values of CO2 and air flow. We found out at which input parameters the nozzle works best, and explained how its performance could be improved.
