(54) СПОСОБ ПО.ПУЧЕНИЯ ЖИДКОГО УДОБРЕНИЯ(54) METHOD FOR LIQUID FERTILIZER
1one
Изобретение относитс к получению жидких удобрений с добавками микроэлементов.The invention relates to the production of liquid fertilizers with the addition of trace elements.
Известен способ получени жидки удобрений путем смещени растворов полифосфата кали с растворами солей микроэлементов fll .A known method for producing liquid fertilizers by displacing potassium polyphosphate solutions with solutions of salts of microelements fll.
Недостаток известного способа необходимость использовани солей микроэлементов, что вл етс дефицитом . ,A disadvantage of the known method is the necessity of using salts of microelements, which is a deficiency. ,
Наиболее близким к предлагаемом по технической сущности вл етс способ получени жидкого удобрени путем разложени фосфатного азотной кислоты в присутствии сульфатных соединений микроэлементов, например сульфата меди, анулита и отвальных продуктов цинкового завода, вводимых в количестве 1,7-3,3% С2. . .Closest to the proposed technical essence is a method of producing liquid fertilizer by decomposing phosphate nitric acid in the presence of sulfate compounds of microelements, such as copper sulfate, anulite and dump products of a zinc plant, introduced in an amount of 1.7-3.3% C2. . .
Недостатком описанного способа вл етс образование продукта с большой в зкостью и высокой температурой кристаллизации.The disadvantage of the described method is the formation of a product with a high viscosity and a high crystallization temperature.
Цель изобретени - устранение указанных недостатков и снижениеThe purpose of the invention is to eliminate these disadvantages and reduce
в зкости и температуры кристаллизации жидких удобрений.viscosity and crystallization temperature of liquid fertilizers.
Поставленна цель достигаетс тем,что дл получени жидкого удобрени путем разложени фосфатного сырь азотной кислотой в присутствии сульфатных соединений микроэлементов в качестве соединени микроэлементов используют ксантогенаты цинка и меди, которые предварительно прокаливают при ЗОО-4ОО и раствор ют в 1/6-1/4 ч. азотной кислоты с последующим смааением полученной массы с остальным количеством азотной кислоты, подаваемой на разложение.The goal is achieved by the fact that to obtain liquid fertilizer by decomposing phosphate raw materials with nitric acid in the presence of sulfate compounds of microelements, zinc and copper xanthates are used as a compound of microelements, which are preliminarily calcined at ZOO-4OO and dissolved in 1 / 6-1 / 4 h nitric acid, followed by smearing the resulting mass with the rest of the nitric acid fed to the decomposition.
Применение указанных добавок приводи.т к улучшению физико-химических свойств жидкого удобрени (снижению в зкости и температуры кристаллизации). Удобрение сохран ет свс о подвижность в течение п тит шести мес цев.The use of these additives leads to an improvement in the physicochemical properties of liquid fertilizer (a decrease in viscosity and crystallization temperature). The fertilizer maintains its mobility for five months or six months.
Сравнительна характеристика продукта, полученного по известному и по предложенному способам представлена в таблице.Comparative characteristics of the product obtained by the known and proposed methods are presented in the table.
