Abstract
V delu je prikazan celotni potek priprave komprimiranega zraka in s tem povezanega razvoja nove tehnologije adsorpcijskega sušenja, komprimiranega z rotacijskim adsorpcijskim sušilnikom. Za potrebe razvoja je bil idejno zasnovan sam sušilnik ter preučen proces adsorpcije vodne pare v nadtlačnih sistemih. Zatem so sledili preračuni delovanja sušilnika, njegovo konstruiranje, izdelava in testiranje prototipa. Sušilnik je namenjen sušenju stisnjenega zraka v industriji. Za razliko od drugih se loči po tem, da je energetsko bolj učinkovit, saj izrablja odvečno toploto brez oljnega večstopenjskega vijačnega kompresorja. V praksi je torej namenjen sušenju zraka v povezavi z brezoljnim kompresorjem, in sicer predvsem v bolj zahtevnih industrijah, kot npr. v farmacevtski, laserski in prehrambni industriji.

Title:Compressed air treatment with rotary adsorption dryer
Abstract:
The main objective of this thesis is development of a new technology of drying of compressed air, drying with rotating adsorption dryer. For this matter a literature survey on the topic of the compressed air drying is presented, with an emphasis on the adsorption drying, including a comprehensive theoretical background of compressed air drying. The idea of the rotating drum is enabling to have a continuous drying process in one pressure vessel, resulting in smaller size and with no pressure losses. Basic calculations have been made to determine the overall size of the prototype. After the calculations were made, the process of design and computer modelling of the prototype followed. After finished modelling, the prototype has been built in order to perform experiments. Prototype was tested, evaluated and compared to similar adsorption dryer. This dryer is used for drying of compressed air in industry. As distinct from others adsorption dryers it is far more efficient, due to use of waste heat of compression of compressor as regeneration flow for the dryer. Therefore this type of dryer is highly applicable with oil-free screw compressors, which are mostly found in high quality industry such as pharmaceutical and food & beverage industry.

Keywords:compressed air, oil free compressors, drying of compressed air, adsorption, use of waste heat, use of heat of compression
