Description
размера кусков материала на выходе печи и корректирующим регул тором, причем выход корректирующего регул тора подключен к другому входу регул тора расхода топлива, а вход соединен с датчиком текущего среднего размера кусков материала.the size of the pieces of material at the kiln outlet and the adjustment regulator, with the output of the adjustment regulator connected to another input of the fuel consumption regulator, and the input connected to the sensor of the current average size of the pieces of material.
На чертеже показана схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит датчик 1 вращающего момента приводного двигател печи 2, корректирующий регул тор 3, регул тор 4 расхода топлива с исполнительным механизмом 5 и блоком 6 управлени , блок 7 регулировани расхода отход щих газов с исполнительным механизмом 8, блок 9 стабилизации расхода шлама с исполнительным механизмом 10, датчик 11 текущего среднего размера кусков материала .The device contains a torque sensor 1 for the drive motor of the furnace 2, a correction regulator 3, a fuel consumption regulator 4 with an actuator 5 and a control unit 6, an exhaust gas flow control unit 7 with an actuator 8, a slurry stabilization unit 9 with an actuator 10, the sensor 11 is the current average size of the pieces of material.
Работает устройство следующим образом.The device works as follows.
Если изменение хода процесса обжига происходит с частотой, период которой меньше времени движени материала но зонам спекани и охлаждени , то регул тор 4 регулирует только на изменени сигнала датчика 1, так как изменени сигнала датчика не проход т через корректирующий регул тор, пропускающий лишь низкочастотные изменени сигнала .If the change in the firing process occurs at a frequency whose period is shorter than the material movement time in the sintering and cooling zones, then controller 4 adjusts only to changes in the signal from sensor 1, since changes in the signal from the sensor do not pass through a correction regulator that passes only low-frequency changes. signal.
Соответственно при увеличении сигнала датчика 1 регул тор уменьшает расход топлива с помощью исполнительного механизма 5 и органа 6 управлени , а при уменьшении сигнала датчика 1 - увеличивает расход тонлива .Accordingly, when the signal of sensor 1 is increased, the regulator reduces fuel consumption by means of actuator 5 and control element 6, and when the signal of sensor 1 decreases, it increases fuel consumption.
Если изменени хода процесса обжига происход т с частотой, период которой больше времени движени материала по зоне спекани и охлаждени , то регул тор 4 реагирует как на изменение сигнала датчика 1, так и на изменение сигнала датчика 11.If changes in the course of the firing process occur with a frequency whose period is longer than the material moving along the sintering and cooling zones, then controller 4 responds to both a change in the signal from sensor 1 and a change in the signal from sensor 11.
При увеличении сигнала датчика 11 уменьшаетс сигнал на выходе корректирующего регул тора 3 и - наоборот. Изменение расхода топлива определ етс алгебраической суммой сигналов на выходе датчика I и корректирующего регул тора 3. Причем преимущественное вли ние датчика 11 в области частот, период которых больше времени движени материала по зонам спекани и охлаждени , обеспечиваетс заданием большего коэффициента усилени по цепи элементов 11 и 3 по сравнению с сигналом датчика 1.As the signal from sensor 11 is increased, the signal at the output of correction regulator 3 decreases and vice versa. The change in fuel consumption is determined by the algebraic sum of the signals at the output of sensor I and the correction regulator 3. Moreover, the predominant influence of sensor 11 in the frequency range, the period of which is longer than the material moving along the sintering and cooling zones, is provided by setting a larger gain over the circuit of elements 11 and 3 compared to sensor signal 1.
Таким образом уменьшаютс отклонени среднего размера кусков материала на выходе печи, что ведет к повышению качества обжига .In this way, the deviations of the average size of the pieces of material at the furnace exit are reduced, which leads to an increase in the quality of the calcination.
Блок стабилизации расхода шлама, введенный в устройство, позвол ет снизить количество возмущений со шламом.The sludge discharge stabilization unit inserted into the device allows reducing the number of sludge perturbations.
