Abstract

Методът и устройството намират приложение в химическите и физикомеханическите процеси на преобразуване. С тях се повишават надеждността и точността при следенето на процесите. При метода се възприема акустичен вибрационен процес, предизвикан от трептенията на наличните в турболентно протичащата течност мехури. Възприетият сигнал се преобразува в електрически сигнал, съответстващ на спектралния състав, който се използва като характеризиращ измертилен сигнал на относителната моментна стойност на турболентния дифузионен процес за косвено контролиране в реално време на превръщането. Устройството съдържа серийно свързани акустичен блок, усилвател, блок за преработване на сигнали и изчислителен блок. Блокът за преработване на сигнали има електрическа верига, която разпределя изходния сигнал на усилвателя по спектрални обхвати и определя принадлежащите към съответните спектрален обхват ефективна и средна стойност и отношението между тях. 8 претенции, 4 фигуриThe method and device find application in chemical and physicomechanical conversion processes. They increase the reliability and accuracy of process monitoring. In the method, an acoustic vibration process is perceived, caused by the oscillations of the bubbles present in the turbulent flowing liquid. The received signal is converted into an electrical signal corresponding to the spectral composition, which is used as a characteristic measurement signal of the relative instantaneous value of the turbulent diffusion process to indirectly control the conversion in real time. The device contains a series-connected acoustic unit, an amplifier, a signal processing unit and a computing unit. The signal processing unit has an electrical circuit that divides the output signal of the amplifier into spectral bands and determines the rms and average values belonging to the respective spectral bands and the ratio between them. 8 claims, 4 figures
