Description
(54) СПОСОБ ПОЛУЧЕНИЯ СУПЕРФОСФАТА(54) METHOD FOR PRODUCING SUPERPHOSPHATE
интенсивного перемешивани и барботажа паром суперфосфатна масса разжижаетс .vigorous stirring and bubbling with steam, the superphosphate mass is liquefied.
Общее врем пребывани в реакторе составл ет 30 мин, температура поднимаетс до 118°С. К концу пребывани в реакторе степень разложени апатита достигает 92% и в газовую фаз} выдел етс дополнительно 1,1 вес. ч. фтора (в виде SiF и HF) и 25,1 вес. ч. воды.The total residence time in the reactor is 30 minutes, the temperature rises to 118 ° C. By the end of their stay in the reactor, the degree of decomposition of apatite reaches 92% and an additional 1.1 wt. Is released into the gas phase}. including fluorine (in the form of SiF and HF) and 25.1 weight. h of water.
Потер воды компенсируетс введением эквивалентного количества пара, в результате чего влажность суспензии практически не мен етс и составл ет 32% по . При такой влажности количество жидкой фазы (с учетом свободной кислотности и растворимых фосфатов) составл ет 126,4 вес. ч. на 252,8 вес. ч. суспензии и таким образом Ж : Т равно 1: 1. В этих услови х суспензи сохран ет достаточную подвижность и может быть передана на гранул цию пульповым насосом.The loss of water is compensated by the introduction of an equivalent amount of steam, as a result of which the moisture content of the suspension remains almost unchanged and is 32%. At this humidity, the amount of the liquid phase (taking into account the free acidity and soluble phosphates) is 126.4 wt. hours 252,8 weight. including suspension and thus G: T is 1: 1. Under these conditions, the suspension retains sufficient mobility and can be transferred to the granulation by a pulp pump.
