Abstract
Przedmiotem zgłoszenia jest granulat kompozytowy o podwyższonej zdolności magazynowania ciepła zawierający rdzeń z materiałem fazowo-zmiennym z grupy parafin oraz otoczkę charakteryzuje się tym, że ma granulometrię od 0,5 do 5 mm, przy czym rdzeń granulatu stanowi aglomerat parafiny oraz drobnoziarnistego aluminium o uziarnieniu do 0,5 mm zawierający od 9,1 do 42,8% wagowych parafiny, a otoczkę stanowi szkło wodne, którego powierzchnia powleczona drobnoziarnistą mączką wapienną o uziarnieniu do 0,5 mm. Zgłoszenie obejmuje także sposób wytwarzania granulatu kompozytowego o podwyższonej zdolności magazynowania ciepła na drodze granulacji w granulatorze znamienny tym, że jako materiał sypki, z którego wytwarza się granulat stosuje się drobnoziarniste aluminium, o wilgotności od 0,1 do 5,0% i uziarnieniu do 0,5 mm oraz drobnoziarnistą mączkę wapienną o wilgotności od 0,1 do 0,5% i uziarnieniu do 0,5 mm, przy czym najpierw do granulatora wprowadza się drobnoziarniste aluminium w takiej ilości, aby stosunek objętości wprowadzonego aluminium do objętości talerza granulatora był równy 0,1 — 0,4, a następnie przez 5 — 10 minut prowadzi się proces granulacji z równoczesnym natryskiwaniem granulowanego złoża parafiną, o temperaturze przemiany fazowej ciało stałe — ciecz do 35°C, dostarczaną do złoża w temperaturze 20 — 30°C, w ilości 200 — 750 g na 1000 g złoża, po czym przez 2 - 6 minut kontynuuje się proces granulacji złoża bez nawilżania parafiną, a następnie przez 2 - 5 minut nawilża się złoże 50 — 99% wodnym roztworem szkła wodnego o temperaturze 10 — 30°C, w ilości 100 — 500 g na 1000 g złoża, w dalszej kolejności prowadzi się proces otoczkowania wilgotnych powierzchni granul drobnoziarnistą mączkę wapienną wprowadzaną do złoża w takiej ilości, że stosunek masy mączki wapiennej do masy granulowanego złoża jest równy 100 – 500 g na 1000 g złoża, po czym kontynuuje się proces mieszając złoże w granulatorze przez czas 1 — 5 minut.The subject of the application is a composite granulate with increased heat storage capacity, containing a core with a phase-changing material from the paraffin group and a shell characterized by a particle size of 0.5 to 5 mm, while the granulate core is an agglomerate of paraffin and fine-grained aluminum with a grain size of up to 0.5 mm containing from 9.1 to 42.8% by weight of paraffin, and the shell is water glass, the surface of which is coated with fine-grained lime flour with a grain size of 0.5 mm. The application also covers a method for the production of composite granules with increased heat storage capacity by granulation in a granulator, characterized in that fine-grained aluminum is used as the loose material from which the granules are produced, with a moisture content from 0.1 to 5.0% and grain size up to 0 , 5 mm and fine-grained lime flour with a moisture content of 0.1 to 0.5% and grain size of up to 0.5 mm, where first fine-grained aluminum is introduced into the granulator in such an amount that the ratio of the volume of aluminum introduced to the volume of the granulator plate is equal 0.1 - 0.4, and then for 5 - 10 minutes the granulation process is carried out with simultaneous spraying of the granulated bed with paraffin, with the phase transition temperature solid - liquid up to 35 ° C, delivered to the bed at a temperature of 20 - 30 ° C, in the amount of 200 - 750 g per 1000 g of the bed, then for 2-6 minutes the granulation process of the bed is continued without wetting with paraffin, and then for 2-5 minutes the PLN is moistened with a 50 - 99% aqueous solution of water glass at a temperature of 10 - 30 ° C, in the amount of 100 - 500 g per 1000 g of bed, then the process of encapsulating the wet surfaces of granules with fine-grained lime flour introduced into the bed in such an amount that the mass of limestone flour to the mass of the granulated bed is equal to 100 - 500 g per 1000 g of bed, then the process is continued by mixing the bed in the granulator for 1-5 minutes.
