Description
Изобретение относитс к свеклосахарному .производству и может быть использовано при определении момент остановки выпарного аппарата на очистку накипи.The invention relates to sugar beet production and can be used in determining when the evaporator is stopped for scaling.
Целью изобретени вл етс по- вьшение точности.The aim of the invention is to improve accuracy.
На фиг. 1 схематически изображено устройство; на фиг. 2 - график изменени амплитуды от частоты. FIG. 1 schematically shows the device; in fig. 2 is a plot of amplitude versus frequency.
Устройство состоит из двух герметичных сосудов 1 и 2, соединенных трубопроводами 3 и 4. Сосуд 1 заполнен воздухом и установлен внутри корпуса выпарного аппарата 5, вблизи стенки теплообменного элемента 6. Сосуд 2 заполнен жидкостью 7, в которую погружен гидрофон 8, соединенный с атмосферой резиновой трубкрй 9. Гидрофон подключен к входу низкочастотного усилител 10, выход которого соединен с входом осциллографа 11. Соединительные трубопроводы в месте выхода из корпуса вьтарного аппарата герметизи- рованы резиновым уплотнением 12.The device consists of two sealed vessels 1 and 2 connected by pipelines 3 and 4. The vessel 1 is filled with air and installed inside the evaporator case 5, near the wall of the heat exchange element 6. The vessel 2 is filled with liquid 7, into which the hydrophone 8 is immersed, connected to the rubber atmosphere pipe 9. The hydrophone is connected to the input of the low-frequency amplifier 10, the output of which is connected to the entrance of the oscilloscope 11. The connecting pipes at the exit from the case of the compact device are sealed with a rubber seal 12.
Устройство работает следующим образом.The device works as follows.

телц, омывает внутренние поверхности теплообменных элементов (труб) 6, вскипает, выдел пузырьки пара, сгущаетс до сиропа и оставл ет на теплопередающей стенке кристаллы отложений накипи. При кипении возбуждаютс звуковые колебани , которые привод т в колебательное движение воздух в герметичном сосуде 1, воздух и воду в трубопроводах 4 и 3 соответственно, а также жидко ть 7 в сосуде 2. Колебани воды в сосуде 2 воспринимаютс гидрофоном 8. Сигнал гидрофона усиливаетс усилителем МО и передаетс на. осциллограф i1. Амплитуда колебаний на экране осциллографа зависит от толщины сло накипи на поверхности теплообменного элемента 6, уменьша сь при его увеличении (фиг. 2), что позвол ет с высокой точностью определ ть толщину сло накипи. Резинова трубка 9 и резиновое уплотнение 12 служат дл снижени уровн помех от вибрации корпуса выпарного аппарата.the body, washes the inner surfaces of the heat exchange elements (pipes) 6, boils up, the release of vapor bubbles, condenses to a syrup and leaves scaling crystals on the heat transfer wall. During boiling, sound vibrations are excited, which vibrate the air in the sealed vessel 1, air and water in pipelines 4 and 3, respectively, as well as liquid 7 in vessel 2. Water oscillations in vessel 2 are sensed by the hydrophone 8. The signal of the hydrophone is amplified by the amplifier MO is transmitted to. oscilloscope i1. The oscillation amplitude on the oscilloscope screen depends on the thickness of the scale layer on the surface of the heat exchange element 6, decreasing with its increase (Fig. 2), which allows determining the thickness of the scale layer with high accuracy. The rubber tube 9 and the rubber seal 12 serve to reduce the level of interference from vibration of the evaporator case.
Применение предлагаемого устройства позвол ет более эффективно выбирать врем остановки выпарного аппарата на очистку и определ ть ее продолжительность.The use of the proposed device makes it possible to more effectively select the stopping time of the evaporator for cleaning and to determine its duration.
