Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania bezwodnego siarczanu magnezu i przykłady jego zastosowania do produkcji składników odżywczych mineralno-organicznych dla roślin w reaktorze izolowanym termicznie, gdzie otrzymujemy bezwodny siarczan magnezu, powstający w wyniku reakcji magnezytu prażonego minimum 80% MgO o rozdrobnieni poniże 0,25 mm w ilości od 50% do 99% masy suchych składników i magnezytu surowego zawierającego minimum 35% MgO o rozdrobnieniu poniżej 0,25 mm, wilgotności poniżej 12% w ilości od 1% do 50% masy suchych składników, z kwasem siarkowym minimum 94% z szybkością od 3 do 10 kg/min w wyniku reakcji powstają opary wody i dwutlenku węgla, które odprowadzane są kominkiem z wentylatorem ssącym zapewniającym 15% wilgotności poniżej punktu rosy, następnie produkt chłodzi się w oddzielnym pojemniku izolowanym od wilgoci lub bezpośrednio używanym np.: do produkcji nawozu mineralno-organicznego.The subject of the application is a method for obtaining anhydrous magnesium sulfate and examples of its use for the production of mineral-organic nutrients for plants in a thermally insulated reactor, where we obtain anhydrous magnesium sulfate, resulting from the reaction of roasted magnesite containing at least 80% MgO with a fineness below 0.25 mm in an amount of 50% to 99% of the mass of dry ingredients and raw magnesite containing at least 35% MgO with a fineness below 0.25 mm, moisture below 12% in an amount of 1% to 50% of the mass of dry ingredients, with sulfuric acid of at least 94% at a rate of 3 to 10 kg/min. As a result of the reaction, water and carbon dioxide vapors are produced, which are discharged through a chimney with a suction fan ensuring 15% humidity below the dew point, then the product is cooled in a separate container insulated from moisture or used directly, e.g. for the production of fertilizer mineral-organic.
