Description
го чтобы этого не происходило, согласно предлагаемому способу, измер ют расход сырьевой муки и параметры газа: разность температур газа в конечной и в начальной ступен х нагрева материала. В зависимости от этих параметров измен ют расход сырьевой муки. В нашем примере требуетс увеличить расход муки, так как температура газов, поступающих в печь, увел-ичИлась.To prevent this from happening, according to the proposed method, the consumption of raw meal and gas parameters are measured: the gas temperature difference in the final and initial heating stages of the material. Depending on these parameters, the consumption of raw meal is changed. In our example, it is necessary to increase the consumption of flour, as the temperature of the gases entering the kiln has increased.
Если материал поступает в четырехступенчатый теплообменник, то датчик, характериризующпй теплообмен в начальной ступени подогрева материала, следует расположить во второй ступени. Теплообмен в этой ступени наиболее чувствителен к колебани м расходов и температуры сырьевой муки и отход щих газов.If the material enters the four-stage heat exchanger, then the sensor characterizing the heat transfer in the initial stage of material preheating should be located in the second stage. Heat transfer in this stage is most sensitive to fluctuations in the flow rate and temperature of the raw meal and waste gases.
Колебани расхода сырьевой муки в процессе регулировани не вызывают заметных колебаний высоты сло материала при прохождении его через печь, что можно объ снить небольшой относительной величиной управл ющих воздействий и выравниванием сло материала при движении его по печи. Следовательно, регулирование подачи сырьевой муки не окажет отрицательного вли ни на режим обжига в печи.Fluctuations in the consumption of raw meal during the adjustment process do not cause noticeable fluctuations in the height of the layer of material as it passes through the kiln, which can be explained by a small relative amount of control actions and leveling of the layer of material as it moves along the kiln. Consequently, regulating the supply of raw meal will not adversely affect the kiln firing mode.
С другой стороны благодар данному способу стабилизируетс теплосодержание материала , поступающего в печь, что существенно облегчит и улучщит услови обжига его во вращающейс печи.On the other hand, thanks to this method, the heat content of the material entering the kiln is stabilized, which will greatly facilitate and improve its firing conditions in the rotary kiln.
Дл осуществлени способа могут быть использованы следующие устройства: дл измерени температур - серийные термопары измерени расхода сырьевой муки-расходомеры типа РМ, дл определени разности температур газа - измерительный блок регул тора , например, типа РПИБ, дл регулировани подачи сырьевой муки - регулирующий прибор типа РПИБ с задатчиком, а также исполнительный механизм и дозирующее устройство, например дисковый питатель .The following devices can be used to implement the method: for measuring temperatures — serial thermocouples for measuring the flow rate of raw meal-type flow meters, for determining the temperature difference of a gas — measuring unit of a regulator, for example, type RPBI, for regulating the supply of raw meal — a regulator type RPIB with the setting device, as well as the actuator and the metering device, such as a disk feeder.
Предлагаемый способ позвол ет эффективно использовать тепло, получаемое от печй, и улучшить услови обжига материала в печи.The proposed method makes it possible to efficiently use the heat obtained from the furnaces and to improve the conditions for burning the material in the furnace.
