Изобретение относитс  к автоматическому управлению работой многокорпусной выпарной батареи и может найти применение в химической промышленности.This invention relates to the automatic control of the operation of a multi-unit evaporator battery and may find application in the chemical industry.

Известен способ автоматического управлени  работой многокорпусной выпарной батареи путем изменени  расхода в емкости среднего раствора в зависимости от концентрации продукционного раствора.There is a known method of automatically controlling the operation of a multi-unit evaporator battery by changing the flow rate in the medium solution tank depending on the concentration of the production solution.

С целью повышени  надежности и качества регулировани  по предлагаемому способу, концентрацию продукционного и среднего растворов регулируют в зависимости от уровн  в емкости среднего раствора.In order to increase the reliability and quality of regulation according to the proposed method, the concentration of the production and medium solutions is adjusted depending on the level in the tank of the medium solution.

При этом концентрацию продукционного раствора уменьшают при изменении уровн  среднего раствора от первого мaкcимaльнo o значени  до второго максимального, а при превышении последнего уменьшают производительность первых корпусов выпарной батареи . Концентрацию среднего раствора уменьшают при изменении уровн  среднего раствора от первого минимального зиачени  до второго минимального подачей исходного раствора .At the same time, the concentration of the production solution is reduced with a change in the level of the average solution from the first maximum o value to the second maximum, and when the latter is exceeded, the performance of the first evaporator battery cases decreases. The concentration of the average solution is reduced with a change in the level of the average solution from the first minimum to the second minimum by feeding the initial solution.

На чертеже представлена схема реализации способа в производстве раствора хлористого кальци .The drawing shows the scheme of implementation of the method in the production of a solution of calcium chloride.

Исходный раствор последовательно подают Б первые корпуса 1 и 2 выпарной батареи, отстойник 3, емкость 4 среднего раствора, откуда насосом 5 - в последний корпус 6, из которого продукционный раствор отбирают дл  переработки в твердый хлористый кальций или на склад готовой продукции.The initial solution is successively fed B first bodies 1 and 2 of the evaporator battery, settler 3, capacity 4 of the medium solution, from where pump 5 to the last body 6, from which the production solution is taken for processing into solid calcium chloride or into the finished goods warehouse.

Давление острого пара, обогреваюшего корпус 1, стабилизируют с помощью регул тора 7. Корпуса 2 и 3 обогревают соковыми парами.The pressure of the hot steam heated by the housing 1 is stabilized with the help of the regulator 7. The shells 2 and 3 are heated with juice vapors.

Уровень жидкости в корпусах поддерживают с помошью регул торов 8.The fluid level in the enclosures is supported by regulators 8.

В автоматическом режиме система регулировани  работает следующим образом.In automatic mode, the control system works as follows.

При по влении возмущени  в системе, например , при уменьшении концентрации исходного раствора, уменьшаетс  концентраци  среднего раствора и в результате этого с помощью регул тора концентрации среднего раствора 9 уменьшают количество среднегоWith the appearance of disturbances in the system, for example, with a decrease in the concentration of the initial solution, the concentration of the average solution decreases and, as a result, with the help of the regulator the concentration of the average solution 9 reduces the amount of average

раствора, поступающего в емкость 4, это вызывает снижение уровн  в емкости.solution entering the container 4, this causes a decrease in the level in the container.

Сигнал, пропорциональный уровню в емкости среднего раствора через прибор 10 ограничени  сигнала и суммирующий прибор ИA signal proportional to the level in the tank of the medium solution through the device 10 limits the signal and the summing device And
