Description

Przedmiotem wynalazku jest sposób wytwarzania nawozu fosforowego z wystepujacych w przyrodzie mi¬ neralów fosforanowo-wapniowych grupy apatytowej. W mineralach tych fosfor wystepuje w postaci nieroz¬ puszczalnych w wodzie i prawie zupelnie nieprzyswajalnych przez rosliny zwiazków o strukturze apatytowej typu A5/PO4/3Z. Proces wytwarzania nawozów fosforowych polega na przeprowadzeniu nierozpuszczalnych w wodzie i nieprzyswajalnych przez rosliny zwiazków fosforu znajdujacych sie w mineralach, w zwiazki przyswa¬ jalne przez rosliny oraz rozpuszczalne w wodzie i w slabych kwasach.The subject of the invention is a process for the production of phosphorus fertilizer from naturally occurring calcium phosphate nals of the apatite group. In these minerals, phosphorus is present in the non-volatile form compounds that are water-soluble and almost completely non-digestible by plants with apatite structure type A5 / PO4 / 3Z. The process of producing phosphorus fertilizers is to carry out insoluble in water and phosphorus compounds that are not absorbed by plants, which are in minerals, plant-friendly, soluble in water and in weak acids.

Jeden z dotychczasowych sposobów wytwarzania nawozów fosforowych polega na spiekaniu w temperatu¬ rze 1100-1200°C surowych fosforytów lub apatytów w piecach obrotowych z soda, wapnem i krzemionka.One of the hitherto methods of producing phosphorus fertilizers consists in sintering at the temperature of 1100-1200 ° C raw phosphate rock or apatite in rotary kilns with soda, lime and silica.

Wytworzony klinkier miele sie nastepnie w mlynach kulowych. Otrzymane termofosfaty znane pod nazwa handlowa jako tomasyna lub supertomasyna zawieraja glównie krzemofosforan wapniowy, nierozpuszczalny w wodzie, który dopiero po wydzieleniu przez korzenie roslinne kwasów organicznych zostaje przetworzony w postac przyswajalna. W zwiazku z tym tomasyna i supertomasyna sa nawozami, które rozsiewa sie juz jesienia.The clinker produced is then ground in ball mills. The obtained thermophosphates known by the name commercially available as tomasin or supertomassin contain mainly calcium silicophosphate, insoluble in water, which is processed only after the release of organic acids by the plant roots in an absorbable form. As a result, Thomas and supertomasyna are fertilizers that are already spreading in autumn.

Innym powszechnie stosowanym sposobem wytwarzania nawozów fosforowych jest sposób wytwarzania superfosfatu prostego, polegajacy na traktowaniu znajdujacego sie w mineralach nierozpuszczalnego w wodzie fosforanu trójwapniowego wodnym roztworem kwasu siarkowego o stezeniu w granicach 62-70%, Wlasciwy proces produkcyjny wymaga zatem wytworzenia najpierw kwasu siarkowego z reguly metoda kontaktowa, zmagazynowania go i rozcienczenia do zadanego stezenia. Surowiec fosforowy przed rozpoczeciem procesu produkcyjnego dokladnie miele sie w mlynie kulowym, a nastepnie miesza sie z kwasem siarkowym w mieszalniku i wprowadza do komory produkcyjnej, w której pod dzialaniem kwasu siarkowego nastepuje przemiana nierozpuszczalnego w wodzie fosforanu trójwapniowego w postac rozpuszczalna w wodzie z jedno¬ czesnym utworzeniem gipsu. W tym czasie masa reakcyjna krzepnie. Po wysuszeniu rozdrabnia sie ja i ewentual¬ nie granuluje, otrzymujac gotowy nawóz wysiewany wczesna wiosna do roslin szybkorosnacych. W sposobie tym w wyniku reakcji kwasu siarkowego z surowcem fosforowym okolo 5% fosforu zawartego w surowcu przechodzi w nierozpuszczalne w wodzie, a rozpuszczalne w slabych kwasach dwu-trój-cztero- i wyzej skondensowane fosfo¬ rany lancuchowe oraz pierscieniowe metafosforany, natomiast ponad 90% fosforu zawartego w surowcu przecho¬ dzi w fosforan jedno wapniowy, dobrze rozpuszczalny w wodzie.2 101814 Nierozpuszczalne w wodzie skladniki nawozowe superfosfatu dzieki powolnemu rozpuszczaniu sie w kwa¬ sach stanowia najcenniejszy skladnik tego nawozu, poniewaz przez dlugi czas zasilaja w fosfor przypowierzchnio¬ wa warstwe gleby. Sa one wykorzystywane przez rosliny w 90%, natomiast, jak wynika z publikacji M.Niklewski, EWenglikowska: Prace naukowe WSE we Wroclawiu, Wroclaw 1968 r., 108 wykorzystanie przez rosliny zwiazków fosforu rozpuszczalnych w wodzie siega zaledwie 15-26%. Wynika stad, ze ponad 75% fosforu zawarte¬ go w superfosfacie prostym wytworzonym metoda mokra, ze wzgledu na swa rozpuszczalnosc w wodzie marnuje sie bezuzytecznie i jest badz splukiwany przez opady atmosferyczne z pól, badz tez ulega procesowi retrogra- dacji. Te sama wysoce ujemna wlasciwosc ma równiez tzw. superfosfat potrójny, bardziej skoncentrowany od superfosfatu prostego, a wytwarzany przez dzialanie wodnego roztworu kwasu fosforowego na surowiec fosfo¬ rowy.Another commonly used method of making phosphorus fertilizers is the production method simple superphosphate, consisting in the treatment of water-insoluble minerals tricalcium phosphate with an aqueous solution of sulfuric acid with a concentration in the range of 62-70%, A proper production process therefore requires first producing the sulfuric acid by the usual method contact, storing it and diluting it to the desired concentration. Phosphorus raw material before starting the production process is thoroughly ground in a ball mill and then mixed with sulfuric acid in the mixer and introduced into the production chamber, where it occurs under the action of sulfuric acid conversion of the water-insoluble tricalcium phosphate into a water-soluble form with a monohydrate early plaster formation. During this time, the reaction mass solidifies. After drying, it is ground up and, if necessary, does not granulate, getting ready fertilizer sown in early spring for fast-growing plants. In this way as a result of the reaction of sulfuric acid with phosphorus raw material, about 5% of the phosphorus contained in the raw material passes in water-insoluble, and weak acid-soluble two-three-four and higher condensed phospho chain wounds and ring metaphosphates, while over 90% of the phosphorus contained in the raw material is stored mono-calcium phosphate, easily soluble in water.2 101814 Water-insoluble superphosphate fertilizers due to slow dissolution in acid succ is the most valuable component of this fertilizer, because they supply the surface with phosphorus for a long time a layer of soil. They are used by plants in 90%, while, according to the publication of M. Niklewski, EWenglikowska: Scientific work of FEZ in Wroclaw, Wroclaw 1968, 108 use by plants Water-soluble phosphorus compounds only reaches 15-26%. It follows that over 75% of phosphorus is present it in simple superphosphate produced by wet method, due to its solubility in water it wastes becomes useless and is washed away by precipitation from the fields, or undergoes a retrographic process dation. The same highly negative property also has the so-called triple superphosphate, more concentrated than simple superphosphate, and produced by the action of an aqueous solution of phosphoric acid on the raw material phospho ditches.

Okazalo sie, ze z surowców mineralnych mozna wytworzyc nawóz fosforowy w sposób prostszy, nie wymagajacy stosowania zarówno wysokich temperatur, jak w metodzie termicznej oraz wodnego roztworu kwasu siarkowego czy fosforowego, jak w metodach mokrych produkcji superfosfatu.It turned out that from mineral resources it is possible to make phosphorus fertilizer in a simpler way, no requiring the use of both high temperatures, as well as thermal method and aqueous acid solution sulfur or phosphorus as in wet superphosphate production.

Sposób wytwarzania nawozu fosforowego z surowców mineralnych wedlug wynalazku polega na traktowa¬ niu surowców mineralnych, takich jak apatyt i fosforyt gazowym trójtlenkiem siarki ewentualnie w mieszaninie z innymi gazami.The method of producing phosphorus fertilizer from mineral raw materials according to the invention is a treatment the use of minerals such as apatite and phosphate rock with sulfur trioxide gas, optionally in a mixture with other gases.

Do produkcji nawozów fosforowych wedlug wynalazku stosuje sie mineralne surowce fosforowe o dowol¬ nym skladzie, róznej wilgotnosci poczatkowej i róznej granulacji. Stosowany gazowy trójtlenek siarki moze pochodzic z dowolnego zródla i moze byc zmieszany z powietrzem, dwutlenkiem siarki, azotem, tlenemi inny¬ mi gazami obojetnymi.According to the invention, phosphorus mineral raw materials of any size are used for the production of phosphorus fertilizers different composition, different initial moisture content and different granulation. The gaseous sulfur trioxide used can come from any source and may be mixed with air, sulfur dioxide, nitrogen, oxygen and other m and with inert gases.

Wedlug wynalazku surowy mineral miele sie i suszy, a nastepnie poddaje dzialaniu gazu reakcyjnego.According to the invention, the raw mineral is ground and dried and then treated with a reaction gas.

W czasie zetkniecia sie trójtlenku siarki zawartego w gazach z ziarnami surowca zawierajacego fosfor nastepuje reakcja, w wyniku której otrzymuje sie nierozpuszczalne w wodzie dwu-trój- i czterofosforany wapnia oraz wyzej skondensowane fosforany liniowe i lnetafosforany. Po oddzieleniu gazów produkt reakcji w postaci sypkiego, niehigroskopijnego i niezbrylajacego sie proszku stanowi gotowy do uzytku nawóz fosforowy.During contact of sulfur trioxide contained in gases with grains of the raw material containing phosphorus, reaction to obtain water-insoluble calcium di- and tetraphosphates, and above condensed linear phosphates and l-metaphosphates. After separation of gases, the reaction product is in a loose form non-hygroscopic and non-caking powder is a ready-to-use phosphorus fertilizer.

Ponad 90% fosforu zawartego w tak wytwarzanym nawozie przyswajaja rosliny dzieki temu, ze fosfor wystepuje w postaci zwiazków nierozpuszczalnych w wodzie, natomiast rozpuszczalnych w slabych kwasach.More than 90% of the phosphorus contained in the fertilizer thus produced assimilate plants due to the fact that phosphorus It occurs in the form of compounds insoluble in water, but soluble in weak acids.

Stopien wykorzystania przez rosliny fosforu zawartego w nawozie fosforowym otrzymanym sposobem wedlug wynalazku jest wiec ponad trzykrotnie wyzszy od stopnia wykorzystania fosforu zawartego w superfosfa- >cie prostym i potrójnym.The degree of utilization by plants of phosphorus contained in the phosphorus fertilizer obtained by the method according to the invention, it is more than three times higher than the degree of utilization of phosphorus contained in superphosphate > simple and triple.
