Abstract
Przedmiotem zgłoszenia jest granulowany nawóz potasowo - fosforowy o przedłużonym działaniu na bazie popiołu ze spalania biomasy, w którym to nawozie zawartość potasu w przeliczeniu na K2O zawiera się w granicach od 10 do 20% wag., a zawartość fosforu w przeliczeniu na P2O5 w granicach od 5 do 10% wag. Nawóz ten stanowi, wysuszony w temperaturze do 200°C, granulat wilgotnej mieszaniny lub pulpy, zawierającej popiół ze spalania biomasy, w ilości nie mniejszej niż 50% wag. w przeliczeniu na gotowy produkt i co najmniej jeden z kwasów takich jak kwas siarkowy o stężeniu 30 - 98%, w ilości do 300 g H2SO4 na 1 kg popiołu ze spalania biomasy lub kwas fosforowy o stężeniu 15 - 65%, w ilości do 200 g P2O5 na 1 kg popiołu ze spalania biomasy, a ponadto ewentualnie produkty, które zawierają fosfor i potas w formie przyswajalnej przez rośliny, przy czym wielkość ziaren granulatu wynosi 1 do 6 mm, a pH odcieku wodnego z gotowego produktu wynosi 4,5 do 9. W zgłoszeniu ujawniono również sposób wytwarzania nawozu potasowo - fosforowego o przedłużonym działaniu na bazie popiołu ze spalania biomasy, obejmujący formowanie granulek w granulatorze mechanicznym obrotowym z mieszaniny zawierającej popiół ze spalania biomasy oraz suszenie uformowanych granulek.The subject of the application is a granulated potassium-phosphorus fertilizer with prolonged action based on ash from biomass combustion, in which the content of potassium calculated as K2O ranges from 10 to 20% by weight, and the phosphorus content calculated as P2O5 within 5 to 10 wt. This fertilizer is, dried at a temperature of up to 200 ° C, granules of a moist mixture or pulp, containing ash from biomass combustion, in an amount of not less than 50% by weight based on the finished product and at least one of the acids such as 30-98% sulfuric acid, up to 300 g H2SO4 per 1 kg of ash from biomass combustion or 15-65% phosphoric acid, up to 200 g P2O5 per 1 kg of ash from biomass combustion, and in addition, possibly products that contain phosphorus and potassium in a form available for plants, the granulate grain size is 1 to 6 mm, and the pH of the effluent from the finished product is 4.5 to 9. The application also discloses a method of producing sustained potassium phosphorus fertilizer based on ash from biomass combustion, comprising forming granules in a rotary mechanical granulator from a mixture containing ash from biomass combustion, and drying the formed granules.
