Изобретение относитс к способам автоматического регулировани процесса получени соды аммиачным методом и может найти применение в химической промышленности.The invention relates to methods for automatically controlling the process of producing soda by the ammonia method and may find application in the chemical industry.
Известен способ автоматического регулировани процесса получени соды путем изменени подачи аммонизированного рассола в карбонизационную колонну в зависимости от уровн в ней и изменени подачи углекислого газа по первому и второму вводам. Однако известный способ характеризуетс низким выходом продукта.There is a known method for automatically regulating the process of soda production by changing the flow of ammoniated brine into the carbonization column depending on the level in it and changing the supply of carbon dioxide through the first and second inputs. However, the known method is characterized by a low yield.
С целью повышени выхода продукта, предлагаетс подачу аммонизированного рассола корректировать по величине и скорости изменени расхода газа второго ввода.In order to increase the yield of the product, it is proposed to supply the ammoniated brine to adjust the magnitude and rate of change in the gas flow rate of the second input.
Выход продукта повышаетс за счет улучшени условий абсорбции углекислого газа и аммиака и условий кристаллизации бикарбоната натри .The yield of the product is increased by improving the absorption conditions of carbon dioxide and ammonia and the crystallization conditions of sodium bicarbonate.
На чертеже изображена принципиальна схема осуществлени способа автоматического регулировани процесса получени соды.The drawing shows a schematic diagram of the method for automatically controlling the process of soda production.
Углекислый газ подают в карбонизационную колонну 1 двум потоками в нижнюю и среднюю части (газ первого и второго вводов). При взаимодействии аммонизированного рассола с углекислым газом получают бикарбонат натри - полупродукт производства соды. С помощью датчиков 2, 3 и 4 измер ют соот2Carbon dioxide is fed into the carbonization column 1 by two streams in the lower and middle parts (gas of the first and second inputs). By reacting ammoniated brine with carbon dioxide, sodium bicarbonate is obtained, a semi-product of soda production. Using sensors 2, 3 and 4, they measure correspondingly 2
ветственно расход аммонизированного рассола , подаваемого в колонну, уровень жидкости в колонне, расход газа второго ввода. С помошью дифференциатора 5, подключенного к выходу датчика 4, измер ют скорость изменени расхода газа второго ввода. Устройство 6 служит задатчнком номинального значени уровн в колонне. Сигнал задани регул тору 7 подачи рассола в колонну формируют как разность между сигналом ycтpoйcтв;J б и суммой сигналов от устройств 3, 4 и 5. Сигнал от датчика 2 используют в качестве сигнала обратной св зи в контуре регулировани подачи рассола. Регул тор 7 воздействует на исполнительный орган 8, установленный на трубопроводе подачи рассола- С помош;ью регулирующих органов 9 и 10 управл ют изменением расходов газа первого и второго вводов.The consumption of ammoniated brine supplied to the column, the liquid level in the column, and the gas flow rate of the second input are valid. Using a differentiator 5 connected to the output of the sensor 4, the rate of change of the gas flow rate of the second input is measured. Device 6 serves as a prime value of the nominal level in the column. The reference signal to the brine supply regulator 7 is formed as the difference between the signal of the spacings; J b and the sum of the signals from devices 3, 4 and 5. The signal from the sensor 2 is used as a feedback signal in the brine feed control loop. The regulator 7 acts on the executive body 8, installed on the brine supply pipeline, with the help of regulators 9 and 10 controlling the change in gas flow rates of the first and second inputs.
