Zeolites are widely used in many industries: in water purification devices as adsorbents, ion exchangers, molecular sieves, in vacuum pumps of the sorption type. Also, zeolites are used as catalysts for many petrochemical and oil refining processes. An innovative application of zeolites is the thermochemical accumulation of heat, which makes it possible to contribute to solving the issue of energy saving and optimal use of resources. For the effective use of zeolites in thermochemical heat accumulators, it is necessary to choose not only the right type of zeolite, but also to organize their regeneration. The stage of regeneration is directly related to the removal of moisture from zeolites, which is carried out in the drying process. The sorption capacity increases significantly during microwave drying, the use of microwave heating allows the process to be carried out much faster, cleaner and with lower energy consumption compared to traditional methods. The regeneration process of 4A and 13X zeolites during microwave drying is analytically investigated. On the basis of an analytical review of the literature, the physical and dielectric characteristics of zeolites, necessary for calculations, were determined. The temperature field in the zeolite massif at different distances from the surface was studied, and the influence of a positive (power of the microwave field) and a negative (caused by moisture vapor) heat source was determined. The influence of the type of zeolite (NaX, NaA1, NaA2, EST-10, clinoptilolite) on the intensity of heating was determined. The influence of the heat transfer coefficient on the surface temperature of the array is shown. Calculations confirm that the mathematical model clearly reflects the influence of physical properties on the temperature distribution in the zeolite layer. [ABSTRACT FROM AUTHOR] |
