Description
(54) СПОСОБ ПОЛУЧЕНИЯ УДОБРЕНИЯ(54) METHOD OF OBTAINING FERTILIZER
1one
Изобрртение относитс к производству минеральных удобрений, а именно к производству суперфосфатов.The invention relates to the production of mineral fertilizers, namely the production of superphosphates.
Известен способ получени двойного суперфосфата путем разложени фосфата фосфорной кислотой при соотношении фосфат : фосфорной кислоты, равном 100 : (90-100) с последующим складским доразложением фосфата, гранул цией и сушкой суперфосфата и классификацией продукта. Содержание воднорастворимой формы РдОу по отношению к общей в этом продукте составл ет 80-85% ГП.A known method of producing double superphosphate by decomposing phosphate with phosphoric acid with a phosphate: phosphoric acid ratio of 100: (90-100) followed by storage of phosphate, granulation and drying of the superphosphate and classification of the product. The content of the water-soluble form of PdOu relative to the total in this product is 80-85% of the HP.
Недостаток данного способа - наличие склада доразложени фосфата и большой расход фосфорной кислоты.The disadvantage of this method is the availability of a phosphate decomposition stock and a high consumption of phosphoric acid.
Наиболее близким к предлагаемому по технологической сущности и достигаемому результату вл етс способ ролучени удобрени , включающий разложение фосфатного сырь фосфорной кислотой с последующей гранул цией и сушкой продукта 2,The closest to the proposed by the technological essence and the achieved result is a method of rolling the fertilizer, including the decomposition of phosphate raw materials with phosphoric acid, followed by granulation and drying of the product 2,
По этому способу фосфатное сырье разлагают фосфорной кислотой при соотношении фосфат : PgOj фосфорной кислоты, равном 100 : 90. Получаема в этих услови х пульпа содержит 40-42% влаги, а сушка гранул идет при температуре отход онх газов И5-125 с.According to this method, phosphate raw materials are decomposed with phosphoric acid at a phosphate: PgOj phosphoric acid ratio of 100: 90. The pulp obtained under these conditions contains 40-42% moisture, and drying of the granules takes place at a temperature of 5,525 sec.
Недостаток способа состоит в теш, что при этом получают продукт с вы10 соким содержанием ваднорастворимой , формы Рд Од более 852 от общего содержани Pfpj). При.внесенЗи такого удобрени в почву значительное количество водиорастворю ой Р Оутер етс из-за вынываш1 кпи св зывани ее с катионами шучтл в нерастворимые в почвенных растввр х соединени .The disadvantage of this method is that they get a product with a high content of water soluble, Rd Od form more than 852 of the total content of Pfpj). When such a fertilizer is applied to the soil, a significant amount of water-soluble oxygen is due to its release from its binding to shchuchtl cations in compounds insoluble in soil solutions.
Цель изобретени - получение удоб рени с понижешшы содержанием вод норастворимой формы The purpose of the invention is to obtain a fertilizer with a lower water content of the soluble form.
Данна цель достигаетс тем, что согласно способу получени удобрени , включающем разложение фосфатThis goal is achieved by the fact that according to the method of producing fertilizer, including the decomposition of phosphate
