20.500.12556/DKUM-73243 Razvoj namizne filtrirne naprave za cigaretni dim magistrsko delo Development of a desktop purifier for cigarette smoke V tem magistrskem delu smo predstavili koncept, razvoj, ter samo izvedbo naprave, ki dim očisti določenih škodljivih snovi, ter s tem pomaga izboljšati kakovost zraka v notranjih prostorih. Naš cilj je bil razviti napravo, ki bo dosegla optimalno razmerje med količino zajetega zraka, ter stopnjo očiščenja zraka, hkrati pa bo dovolj majhna, da jo bo možno postaviti na pisalno mizo. S pomočjo tehničnih podatkov, ki so nam jih posredovali proizvajalci, smo najprej analitično izračunali parametre naprave in filtracije. Nato smo s pomočjo računalniške dinamike tekočin optimizirali obliko naprave, z namenom, da bi dosegli največji možen pretok zraka skozi napravo. Z dobljenimi rezultati smo napravo na koncu tudi izdelali. Napravo je v praksi tudi preizkusilo več ljudi, ki so bili z delovanjem zelo zadovoljni. This master’s thesis represents the concept, development and the actual device, that purifies the smoke of some harmful substances, which in effect improves indoor air quality. Our goal was to create a device, which has the best ratio of flowrate and smoke purifying efficiency, while still being small enough to be placed on a desktop table. With the help of technical data provided by different manufacturers, parameters of filtration and device performance were first calculated analytically. At the end we used computational fluid dynamics, for device design optimization, to achieve the highest possible flowrate through the device. Obtained results were then used to manufacture the prototype of the device. The device was also tested by multiple users, who were all satisfied with its performance.
