Abstract

Sisteme za proizvodnjo in pripravo komprimiranega zraka najdemo skoraj v vsakem proizvodno usmerjenem podjetju, bolnišnici, farmacevtskem podjetju ali živilskem obratu. Vsak sistem za proizvodnjo in pripravo komprimiranega zraka vsebuje tudi filtre za komprimiran zrak, katerih namen je izločanje nečistoč iz komprimiranega zraka, ki bi sicer poškodovale naprave, gnane s komprimiranim zrakom. Delci v komprimiranem zraku lahko tudi kontaminirajo proces pri katerem komprimiran zrak stopi v stik z izdelkom. Ob pretoku stisnjenega zraka skozi filter prihaja do tlačnih izgub, kar zaradi posledično večje porabe energije povzroča finančne izgube in poslabšanje okoljskega odtisa. V tej diplomski nalogi smo se osredotočili na načrtovanje filtrov z manjšim tlačnim padcem ob nespremenjenih gabaritih filtra in ob nespremenjeni granulaciji filtrirnih delcev. Pri tem smo optimizirali geometrijo gubanega filtrirnega papirja, ki je sestavni del filtrskega vložka. Različne geometrije smo analizirali s pomočjo testiranj in računalniških simulacij. Pri testiranjih smo analizirali tudi vpliv vlažnosti na tlačni padec. Ugotovili smo, da se tlačni padec s povečevanjem filtrirne površine najprej znižuje, na neki točki pa potem začne naraščati. Ta točka predstavlja optimalno geometrijo gub. V diplomskem delu smo definirali enačbo, ki nam poda optimalno število gub in navedli priporočila glede višine gube

Secondary title: Optimization of Compressed Air Filters
Secondary abstract: Compressed air generation and treatment systems can be found in almost every productionoriented company, hospital, pharmaceutical company or food processing plant. Every compressed air generation and treatment system includes compressed air filters. The filters remove mechanical impurities from the compressed air which could otherwise damage the machines and equipment driven by the compressed air. Particles in the compressed air can also contaminate the process where the compressed air comes into contact with the product. When the compressed air passes through the filter, losses occur in the form of a pressure drop, resulting in higher energy consumption, higher operating costs and a larger ecological footprint. In this diploma thesis we focused on the design of filters with lower pressure drop while maintaining the same filtration properties. We optimized the geometry of pleated filter paper, which is an integral part of filter elements. Different geometries were analysed by means of testing and computer simulations. We also tested the impact of humidity on the pressure drop. We found that the pressure drop decreases with the increase of filtration surface at first, but then starts increasing at some point. This point represents optimal geometry of pleated paper. In the diploma thesis we have defined an equation that provides the optimal number of wrinkles for filter elements of any dimensions and gave recommendations about the folding height.
