Description
Изобретение относитс к способам получени сложных фосфорных удобрений. Известны способы получени сложных фосфорных удобрений путем термической обработки шихты , содержащей фосфорит, минеральную добавку , например астраханит. Недостатками известных способов вл етс то, что сумма усво емых питательных веществ в удобрении невелика.This invention relates to methods for producing complex phosphate fertilizers. Methods are known for producing complex phosphorus fertilizers by heat treating a mixture containing phosphorite, a mineral additive, such as astrakhanite. The disadvantages of the known methods are that the amount of nutrients absorbed in the fertilizer is small.
С целью увеличени суммы питательных веществ в усво емой форме и расщирени сырьевой базы предложен способ получени сложных фосфорных удобрений путем термической обработки щихты, содержащей природный фосфорит и в качестве минеральной добавки Актюбинский полигалит.In order to increase the amount of nutrients in an assimilable form and the expansion of the raw material base, a method is proposed for obtaining complex phosphate fertilizers by heat treating bribery containing natural phosphorite and as a mineral additive Aktobe polygalite.
Применение полигалита позвол ет получать удобрение, содержащее в усво емой форме одновременно фосфор, калий, магний и тем самым повыщает общую сумму питательных веществ до 32-36%.The use of polyhalite makes it possible to obtain fertilizer that contains phosphorus, potassium, magnesium in an assimilable form at the same time, and thereby increases the total amount of nutrients by up to 32-36%.
С целью обесфторивани природных фосфоритов в щихту добавл ют кремнезем, древесный уголь и обрабатывают ее вод ным паром.In order to defluorize natural phosphorites, silica, charcoal are added to the batch and treated with water vapor.
Пример 1. Используют полигалит и фосфорит Актюбинского месторождени . Фосфорит (Богдановский участок), содержащий 18,71 % PaOs и полигалит состава: К2О 15,19%, MgO 6,46%, СаО 18,2%, 5Оз51,9% - сплавл ют при температуре 1450-1500°С с последующим выливанием расплава в воду. Врем плавлени 5 мин.Example 1. Polygale and phosphorite of Aktobe deposit is used. Phosphorite (Bogdanovsky plot) containing 18.71% PaOs and polygalyt composition: K2O 15.19%, MgO 6.46%, CaO 18.2%, 5Oz51.9% - fused at a temperature of 1450-1500 ° C, followed by pouring melt into water. Melting time 5 min.
При составе щихты: 10 вес. ч. фосфорита, 8 вес. ч. полигалита, 0,7 вес. ч. угл (в данном случае древесного) - получают продукт, содержащий в усво емой форме PzOs 15-When the composition of the sheet: 10 wt. including phosphorite, 8 wt. h. polyhalite, 0.7 wt. coal (in this case wood) - get a product containing in digestible form PzOs 15-
16%, КзО 9-10%, MgO 6,2%, не тер ющий при длительном хранении своих свойств.16%, KzO 9-10%, MgO 6,2%, not losing during long-term storage of its properties.
Пример 2. Спекание провод т в лабораторной вращающейс печи длиной 800 мм, диаметром 40 мм; угол наклона печи 10°, скорость 1 об/мин, температура в гор чей зоне 1250-1260°С, врем нахождени щихты в гор чей зоне 20-25 мин, .противотоком к щихте подают вод ной пар. Состав щихты: 10 вес. ч. фосфорита Каратау (25,2% Р-Оз), 8 вес. ч. полигалита ( MgSO :2CaSO4-2H2O), 1 вес. ч. двуокиси кремни (SiO2 98%) и 1,5 вес. ч. древесного угл . В этом случае в конечном продукте содержитс 18,8% , 6,5% MgO, 8,8% К2О,Example 2. Sintering was carried out in a laboratory rotary kiln with a length of 800 mm and a diameter of 40 mm; oven angle of 10 °, speed of 1 rpm, temperature in the hot zone 1250-1260 ° C, residence time of the precipitator in the hot zone 20-25 min. Steam is supplied to the condensate flow. Ingredients: 10 wt. including phosphorite Karatau (25.2% P-Oz), 8 wt. including polyhalite (MgSO: 2CaSO4-2H2O), 1 weight. including silicon dioxide (SiO2 98%) and 1.5 weight. wood charcoal In this case, the final product contains 18.8%, 6.5% MgO, 8.8% K2O,
полностью растворимых в 2%-ном растворе лимонной кислоты. Содержание фтора 0,2- 0,4%.completely soluble in 2% citric acid solution. The fluorine content is 0.2–0.4%.
Пример 3. Услови спекани , как и в примере 2. Состав щихты: 10 вес. ч. фосфорита , 1 вес. ч. полигалита; 1 вес. ч. SiO2 и 1,5 вес. ч. древесного угл .Example 3. Sintering conditions, as in Example 2. Components: 10 wt. including phosphorite, 1 wt. h. polyhalitis; 1 weight. including SiO2 and 1.5 wt. wood charcoal
В конечном продукте содержитс 16,9% PoOs, 7,2% MgO 11,2% КаО, растворимых в 2%-ном растворе лимонной кислоты. Содер3 получают различное соотношение между фосфором и калием, что делает удобрение более универсальным и, следовательно, применимым на различных почвах. Предмет изобретени 1. Способ получени сложных фосфорных удобрений путем термической обработки ших5 4 ты, содержаи ей в своем составе фосфорит и минеральную добавку, отличающийс тем, что, с целью увеличени суммы питательных веществ в усво емой форме и расширени сырьевой базы, в качестве минеральной добавки примен ют полигалит. 2.
