VISUALIZATION SYSTEM OF DUST COLLECTION EQUIPMENT OPERATION WITH CONTROL OF ITS MAIN TECHNOLOGICAL PARAMETERS IN CONDITIONS OF CEMENT PRODUCTION

Abstract

Article is devoted to study of gas purification technological process by electrofilters in conditions of cement production in order to develop automated control system and technological parameters visualization, which allows to control process in real time, to identify emergencies. This issue is urgent task given that cement industry is increasing its production capacity every year, and reducing emissions of dusty and toxic gases will avoid paying fines and reduce emissions payments. To achieve this goal was analyzed technological process and existing gas dedusting control system operation and it is determined that the existing system can be improved by applying new approaches and methods of control and visualization of system`s work by itself in real time. Scheme of particle motion in electrofilter and scheme of gas motion under the action of electric wind are investigated, on basis of which technological process mathematical description was executed and shaking control in which correction of shaking force that allows to carry out effective shaking at minimum destruction of electrostatic precipitator equipment. The developed control and visualization system corresponds to three-level structure, where at the first level technological process parameters are measured, at the second level logical control of mechanisms according to control algorithms is realized, and at the third level control system interacts with operators, collected and processed and archived online information about status of equipment. The practical significance lies in application of automated control system and visualization of main technological parameters to obtain real-time operational information as process itself, and to optimize electrodes shaking mode when cleaning the gases of cold end of furnace from dust in electrofilter.
