Description
лирующего прибора 8. Датчики температуры 9 и 10 через преобразователи 11 и 12 контролируют текущее значение входной и выходной температуры охлажда1с дей летки воды, а датчиком расхода 13 и преобразовател 14 - расход ;Охлаждающей воды. Сигнал от преобразовател 14 поступает непосредственно на вход блока умножени 15, а от преобразователей 11 и 12 - через cyNtMHpyromee устройство 16. Сигнал с выхода блока умножени 15 поступает на вход дифференциатора 17, св занного с входом регулирующего прибора 8, который через исполнительный механизм 18 управл ет переметением регулирующего органа подачи сла .бого белого щелока 19.8. Temperature sensors 9 and 10 through the converters 11 and 12 monitor the current value of the input and output temperature of the cooling water, and the flow sensor 13 and the converter 14 control the flow; Cooling water. The signal from converter 14 is fed directly to the input of multiplier 15, and from converters 11 and 12 through cyNtMHpyromee device 16. The signal from the output of multiplier 15 is fed to input of differentiator 17 connected to the input of control device 8, which is controlled by actuator 18 by overturning the regulatory authority for the supply of weak white liquor 19.
При изменении режима работы содорегенерационного котлоагрегата проиходит изменение сигнала на выходе блока умножени 15, определ емого изменением сигналов от преобразовател 14 и от суммирующего устройства 16, который с помощью дифференциатора 17 преобразовываетс в динамический сигнал, подаваемый на вход регулирующего прибора 8. Произведение сигналов по разности температур охлаждающей летки воды на входеи выходе от суммирующего устройства 16 и расходу охлаждающей воды- от преобразовател 14 определ ет расход плава, поступающего в бак-растворитель плава „3, вл ющегос основным возмущающим воздействием дл регулировани процента уноса солей. Введение дифференциатора 17, формирующего динамический сигнал по расходу пйава обеспечивает реализацию частичной инвариантности к этому возмущающему воздействию, при этом динамический сигнал по расходу плава исчезает в статическом режиме, а следовательно , не вноситс в статическую ошибку при реализации данного способа, что позвол ет повысить качество регулировани .When the operating mode of the regenerative boiler is changed, the signal at the output of multiplier 15 is changed, determined by the change of signals from converter 14 and from summing device 16, which is transformed by means of differentiator 17 into a dynamic signal fed to the input of regulating device 8. Production of signals by temperature difference water cooling tap at the inlet of the outlet from the totalizer 16 and the flow of cooling water from the converter 14 determines the flow rate of the water entering the ba -rastvoritel melt "3 is yuschegos main perturbing influence for adjusting percent ash salts. The introduction of a differentiator 17 that generates a dynamic signal according to flow rate Pyava provides the implementation of partial invariance to this disturbing effect, while the dynamic signal disappears in a static mode by the flow rate of the melt and, therefore, is not introduced into a static error during the implementation of this method, which improves .
Ожидаемый годовой технико-экономический эффект от данного способа применительно к содорегенерационном котлоагрегату типа СРК-700 составл ет 20 тыс. руб. в основном за сче уменьшени потерь химикатов.The expected annual technical and economic effect of this method in relation to the soda recovery boiler unit of the SRK-700 type is 20 thousand rubles. mainly due to the reduction of chemical losses.
