Изобретение относитс к автомати ческому управлению, преимущественно ., к автоматическому управлению химическими процессами.This invention relates to an automatic control, mainly automatic control of chemical processes.
Известен спосо.б автоматического управлени процессом выпаривани в аппаратероторного типа путем регулировани подачи исходного раствора в зависимости от уровн выпариваемого раствора с коррекцией по суммарному показателю значений расхода и температуры теплоносител в аппарат и регулировани числа оборотов двигател мешалки по концентрации выпариваемого раствора в испарителе 1.Known is the method of automatic control of the evaporation process in the apparatus type by adjusting the supply of the initial solution depending on the level of the evaporated solution, corrected for the total flow rate and temperature of the coolant to the apparatus and adjusting the engine speed of the evaporator according to the concentration of the evaporated solution in the evaporator 1.
Наиболее близким по технической сущности к изобретению вл етс способ автоматического управлени процессом выпаривани путем регулировани подачи исходного раствора в Зависимости от суммарного значени уровн в мернике и приемнике раствора, изменени числа оборотов ротора в зависимости от уровн раствора в приемнике 2 .The closest to the technical essence of the invention is a method of automatic control of the evaporation process by adjusting the supply of the initial solution depending on the total level value in the measuring device and the solution receiver, changing the number of rotor revolutions depending on the level of the solution in the receiver 2.
Однако этот способ не позвол ет получать высокое качество выходного продукта.However, this method does not allow to obtain high quality of the output product.
Цель изобретени - улучшение ка .чества целевого продукта за счетThe purpose of the invention is to improve the quality of the target product by
повышени точности управлени процессом выпаривани .improving the control accuracy of the evaporation process.
Это достигаетс тем, что подачу исходного раствора регулируют в зависимости от текущего значени его расхода с коррекцией пО числу оборотов ротора, которое измен ют в зависимости от расхода выходного продукта .This is achieved in that the supply of the initial solution is controlled depending on the current value of its flow rate with correction from the rotor speed, which varies depending on the flow rate of the output product.
10 На чертеже дана схема реализации способа.10 In the drawing, a diagram of the implementation of the method.
Способ осуществл ют следующим образом .The method is carried out as follows.
В пленочный аппарат 1 пленочного 5 типа подаетс исходный раствор,вторичный пар удал етс вверху аппара . та 1 и конденсируетс в теплообменнике 2. Дл вращени ротора используют двигатель 3. Расход выходного продукта измер ют датчиком 4, выходной сигнал которого поступает в оптимизирующее устройство 5, выход которого , в зависимости от расхода входного продукта, управл ет работой дви .25 гател 3, измен число оборотов.Расход исходного раствора измер ют дат чикЬм б. Число оборотов ротора измер ют датчиком 7, св занным с преобразуквдим блоком 8, который преобразует поступающий сигнал и определ етThe initial solution is fed to the film apparatus 1 of the film type 5, the secondary vapor is removed at the top of the apparatus. This 1 is condensed in heat exchanger 2. A motor 3 is used to rotate the rotor. The flow rate of the output product is measured by a sensor 4, the output of which is fed to an optimizing device 5, the output of which, depending on the input product flow rate, controls the operation of the engine 25 by changing the number of revolutions. The flow rate of the initial solution is measured by the datum b. The rotor speed is measured by a sensor 7 associated with a conversion unit 8, which converts the incoming signal and determines
