Description
Изобретение относитс к сушильной технике и, в частности, к автоматическому управлению процессом распылительной сушки и фильтрации продуктов сушкн.The invention relates to a drying technique and, in particular, to the automatic control of the spray-drying process and the filtration of drying products.
Известен способ автоматического управлени гфоцессом распьшительной сушкк . и фильтрации продуктов сушки путем воздействи на расход удал емого сушильного агента по перепаду давлени на фильтThere is a known method of automatically controlling a hardening process. and filtering the drying products by influencing the flow rate of the drying agent to be removed by the pressure drop across the filter.

Однако известный способ не позвол ет достигнуть требуемой точности.However, the known method does not allow to achieve the required accuracy.
Цель изобретени - повышение точности .The purpose of the invention is to improve accuracy.
Поставленна цель достигаетс тем, что дополнительно измер ют температуры агента на выходе каждого фильтра с последующим воздействием на расход подводимого к фильтрам агента.This goal is achieved by additionally measuring agent temperatures at the outlet of each filter, followed by affecting the flow rate of the agent supplied to the filters.
На чертеже представлена блок-схема го устройства, реализующа предлагаемый способ.The drawing shows a block diagram of a device implementing the proposed method.
Устройство содержит сушилку I, датчики 2 давлени на выходе из сушилкиThe device includes a dryer I, pressure sensors 2 at the outlet of the dryer
и на циклонах 3, соединенные с регул торами 4-6 с датчиками 7 температуры, рукавные фильтры 8, исполнительные механизмы 9, задвижки 1О и задатчик Ц.and on cyclones 3, connected to regulators 4-6 with temperature sensors 7, bag filters 8, actuators 9, valves 1O and setpoint Ts.
Устройство работает следующим образом .The device works as follows.
Подана воздуха на рукавные фильтры 8 осуществл етс изменением положени задвижки Ю по сигналам регул торов 6, а на исполнительные механизмы 9 воздействует по сигналу регул тора 5 и 4, которые получат сигналы от датчиков 2. Регул торы 6 работают по сигналам датчиков 7 и задатчика 11.Air is fed to the bag filters 8 by changing the position of the valve U according to the signals from the regulators 6, and to the actuators 9 it acts on the signal from the regulator 5 and 4, which will receive signals from the sensors 2. The regulators 6 work according to the signals of the sensors 7 and the setting device 11 .
Таким образом производитс дополнительна корректировка работы рукавичных фильтров по температуре материала после них и этим достигают указанный положительный эффект.In this way, an additional adjustment is made to the operation of the mitten filters according to the temperature of the material after them, and this achieves the indicated positive effect.
