Abstract
Przedmiotem zgłoszenia jest granulat kompozytowy o podwyższonej zdolności magazynowania ciepła zawierający rdzeń z materiałem fazowo-zmiennym z grupy parafin oraz otoczkę charakteryzujący 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 drobnoziarnistym cementem budowlanym o uziarnieniu do 0,5 mm. Zgłoszenie obejmuje też sposób wytwarzania granulatu kompozytowego o podwyższonej zdolności magazynowania ciepła na drodze granulacji w granulatorze polegający na 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 drobnoziarnisty cement budowlany 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 drobnoziarnistym cementem budowlanym wprowadzanym do złoża w takiej ilości, że stosunek masy cementu 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 grain size of 0.5 to 5 mm, the granulate core being 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 construction cement with a grain size of 0.5 mm. The application also covers a method of producing composite granules with increased heat storage capacity by granulation in a granulator, which consists in using fine-grained aluminum as the loose material from which the granules are produced, with a moisture content of 0.1 to 5.0% and grain size up to 0.5 mm and fine-grained construction cement with a moisture content of 0.1 to 0.5% and a grain size of 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 disc is equal to 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 the granulation process of the bed is continued for 2-6 minutes without wetting with paraffin, and then for 2-5 minutes it is moistened the bed 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 the bed, then the wet granule surfaces are coated with fine-grained construction cement introduced into the bed in such an amount that the ratio the mass of cement 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.
