(54) СПОСОБ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ ПРОЦЕССОМ СУШКИ СЫПУЧИХ МАТЕРИАЛОВ(54) METHOD FOR AUTOMATIC CONTROL OF DRYING BULK MATERIALS
1one
Изобретение относитс к сушильной технике , а именно к авто.матизации процесса сушки сыпучих 1материалов.The invention relates to a drying technique, namely, to automating the process of drying loose materials.
Известны способы автоматического уп- равлени процессом сушки сыпучих материалов , преимушественно древесной стружки , путем воздействи на изменение теплоподвода по температуре сушильного агента, измер емой в трех точках - перед сушилкой , в средней ее части и после сушилки 1.Methods are known for automatically controlling the drying process of bulk materials, mainly wood chips, by influencing the change in heat supply in terms of the temperature of the drying agent, measured at three points - before the dryer, in its middle part and after the dryer 1.
Однако способ не позвол ет достигнуть требуемого качества управлени секционной сушилкой.However, the method does not allow to achieve the desired quality control of the sectional dryer.
Цель изобретени - повышение качества управлени секционной сушилкой.The purpose of the invention is to improve the quality control of a sectional dryer.
Поставленна цель достигаетс тем, что среднюю точку дл измерени температуры выбирают .между секци ми сушилки, а воздействие на изменение теплоподвода осуществл ют по разности между скорост ми сушки в секци х, определ емыми по разности температур агента, измеренных соответственно в первой и в средней, в средней и в третьей точках.The goal is achieved by the fact that the middle point for measuring the temperature is chosen between the sections of the dryer, and the effect on the change in heat supply is made by the difference between the drying rates in the sections determined by the temperature difference of the agent, respectively in the middle and in the third points.
На чертеже представлена блок-схема устройства, реализующа предлагаемый способ управлени .The drawing shows a block diagram of a device implementing the proposed control method.
Устройство содержит сушильный барабан 1, предварительную секцию сушилки 2, топку 3, регулирующий орган 4 с исполнительным механизмом 5, датчика.ми 6-8 температуры, задатчиками 9-12, сумматора .ми 13-15, регул тором 16.The device contains a drying drum 1, a preliminary section of the dryer 2, a firebox 3, a regulator 4 with an actuator 5, sensors 6–8 temperatures, set points 9–12, an adder 13–13, controller 16.
Способ осушествл ют следующим образом .The method is carried out as follows.
10ten
На исполнительный механизм 5, а следовательно , на расход топлива и подвод тепла воздействуют по сигналам от трех датчиков 6-8 температуры, измереннойThe actuator 5, and therefore, the fuel consumption and heat supply is influenced by signals from three temperature sensors 6-8, measured
5 соответственно перед сушилкой, после первой секции 2 и после барабана 1, преобразу таким образом, чтобы в результате су.ммировани на сумматорах 13-15 сфор.мировать сигнал о скорости изменени температуры сушильного агента в указанных трех5, respectively, before the dryer, after the first section 2 and after the drum 1, is converted so that as a result of summation on the accumulators 13-15, a signal about the rate of change of the temperature of the drying agent in these three
точках.Таким образом регул тор 16 стабилизирует указанные скорости изменени положени исполнительного механизма 5. points. Thus, the controller 16 stabilizes the indicated rates of change in the position of the actuator 5.
В результате внедрени изобретени возможно повысить качество сушки.As a result of the implementation of the invention, it is possible to improve the quality of drying.
