Description
действий также смещает оптимальное значение температуры реакционной массы.action also shifts the optimum temperature of the reaction mass.
Цель изобретени -- интенсификаци процесса нитровани и обеспечение безаварийности его проведени .The purpose of the invention is to intensify the process of nitration and ensure the reliability of its implementation.
Поставленна цель достигаетс тем что измеренные значени температуры, электроводности и концентрации исходного реагента реакционной массы суммируют и сравниваютс заданныгли значени ми сумм, а регулирование расходов реагента и хладагента осуществл ют по знакам отклонени полученных сукад от заданных.This goal is achieved by the fact that the measured values of temperature, electrical conductivity and concentration of the initial reagent of the reaction mass are summed up and the given values are compared, and the reagent and refrigerant costs are controlled by the signs of the deviation of the received flows from the set ones.
На чертеже представлена схема реализации способа управлени процессом нитровани .The drawing shows the implementation scheme of the process for controlling the nitration process.
Устройство дл осуществлени способа содержит реактор 1 с перемешивающим устройством и тепловой рубашкой 2, первичные преобразователи температуры 3, электропроводности 4 и концентрации 5, блоки б и 7 суммировани с умножением слагаемых на посто нный коэффициент, блоки 8 и 9 сравнени , знакочувствительные релейные блоки 10 и 11, прибор 12 управлени дозатором реагента, клапан 13 регулировки расхода хладагента, Дозаторы 14 и 15 реагентов.An apparatus for carrying out the method comprises a reactor 1 with a mixing device and a thermal jacket 2, primary temperature converters 3, electrical conductivity 4 and concentration 5, blocks B and 7 summation with multiplication of the terms by a constant factor, blocks 8 and 9 of comparison, sign-sensitive relay blocks 10 and 11, the reagent metering control device 12, the refrigerant flow control valve 13, the reagent dispensers 14 and 15.
Система работает следу бщим обт разом. The system works as follows.
Сигналы от первичных преобразователей 3, 4 и 5 поступают в блоки 6 и 7 суммировани , где производитс их алгебраическое сложение с посто нными весовыми коэффициентами, значени которых выбираютс исход из ограничений на электропроводность, концентрацию и температуру, определ емых па услови м безопасного и интенсивного проведени процесса, В блоках 8 и 9 величины сумм срапни .ваютс с заданными значени ми. В зависимости от знака на выходе блока 8 релейный блок 10 переводит в один из двух режимов ,прибор, управ .л ющий работой дозатора 14 реагента , а блок 11 измен ет подачу хладагента через клапан 13.The signals from the primary converters 3, 4 and 5 enter the summation blocks 6 and 7, where they are algebraically combined with constant weighting coefficients, the values of which are chosen based on the limitations on electrical conductivity, concentration and temperature determined by the conditions of safe and intensive process, In blocks 8 and 9, the amounts of the total are matched with the given values. Depending on the sign at the output of the block 8, the relay block 10 converts into one of two modes, the device controlling the operation of the reagent dispenser 14, and the block 11 changes the refrigerant flow through the valve 13.
Предлагаемый способ управлени позвол ет измен ть температурный режим реактора в зависимости от состава реакционной массы с целью интенсификации выхода целевого продукта и обеспечени посто нства егр качества при безаварийности процесса.The proposed control method allows changing the temperature regime of the reactor depending on the composition of the reaction mass in order to intensify the yield of the target product and to ensure the constance of quality rd while the process is trouble-free.
