Description
Изобретение относитс к способам управлени процессом кислот .ного разложени концентратов и может быть применено в химической промыш- ленности, в частности при производстве борной кислоты.The invention relates to methods of controlling the process of acid decomposition of concentrates and can be applied in the chemical industry, in particular in the production of boric acid.
Известен способ управлени путем визуального контрол периодически . отбираемой .пробы из смесител , определени скорости ее загустевани с одновременной проверкой щупом твердости массы в камере и изменени расхода килоты или концентрата (1.A known method of control is by visual inspection periodically. samples taken from the mixer, determine the rate of its thickening while checking with the probe the mass hardness in the chamber and changing the flow rate of the kilo or concentrate (1.
Однако при этом способе эффективное управление процессом невозможно вследствие низкой точности и достоверности контрол .However, with this method, effective process control is impossible due to low accuracy and reliability of control.
Наиболее близким по технической сущности к изобретению вл етс способ управлени процессом кислотного разложени концентратов на установке , вк.г1ючающей смеситель и реак1;ионную камеру, путем регулировани соотношени концентрата и кислоты 2., .The closest to the technical essence of the invention is a method for controlling the process of acid decomposition of concentrates in a plant, combining a mixer and a reaction chamber, by adjusting the ratio of concentrate to acid 2.,.
Недостатком такого способа управлени вл етс избыточный расход кислоты дл достижени заданной степени разложени , вызванной длительностью пребывани смеси в смесителеThe disadvantage of this method of control is the excessive consumption of acid to achieve a given degree of decomposition caused by the duration of the mixture in the mixer.
и камере и значительным запаздыванием результатов анализа готового продукта.and the camera and a significant delay in the analysis of the finished product.
Цель изобретени - снижение удельного расхода кислоты при заданной степени разложени концентрата.The purpose of the invention is to reduce the specific consumption of acid at a given degree of decomposition of the concentrate.
Поставленна цель достигаетс тем, что соотношение концентрата и кислоты регулируют в зависимости от из- The goal is achieved by adjusting the ratio of the concentrate to the acid depending on the

На чертеже показана схема реализа15 ции данного способа на примере сернокислотного разложени датолитового концентрата, имеющего в своем составе карбонат кальци .The drawing shows the scheme for implementing this method by the example of the sulfuric acid decomposition of a datolite concentrate containing calcium carbonate.
Способ осуществл етс следующим The method is as follows.

В смеситель 1 непрерывно подают концентрат и серную кислоту, после чего смесь поступает в реакционную камеру 2, где происходит окончательное разложение концентрата. Датчики In the mixer 1, the concentrate and sulfuric acid are continuously supplied, after which the mixture enters the reaction chamber 2, where the final decomposition of the concentrate takes place.
