Analysis of systems of transport valves of sugar-houses with elements of automatic control

For upgrading productions of sugar and decline of his prime price, without large capital investments, it is necessary to provide introduction of the systems of automation of the technological stations of saccharine production. And also creation of single control system by the streams of saccharine production and his energy consumptions. On the modern production of sugar from a beet, at classic technology of his production, such stages of processing of beet must be present as: serve, wash, clearing, diffusion, defecosaturation, boil-off, crystallization, drainage and packing. The receipt of maximal rendement depends on the presence of corresponding equipment and pipelines that connect this equipment. Most sugar-houses work on the continuous cycle of receipt of sugar, id est the serve of beet, processing, receipt of juice, cleaning, evaporation and crystallization, come true without stopping at the technological process of work of plant. An equipment that is used for the receipt of sugar has the technical parameters corresponding to the certain productivity. Except a technological equipment with the corresponding productivity, it is necessary to have corresponding pipeline connections between this equipment, that will allow to skip the processed products. The decision of this problem is closely related to the reasonable decision for arrangement of the pipeline and systems of transport valves , for example for: steam, aquatic, runback, exit -juice, syrup and molasses, and also by pipes for a lime and limewater. Permanent exploitation of pipelines results in education on the midwalls of various sedimentations and scum. In addition, the sections of pipelines not always are correctly neat under the necessary productivity of plant. The search of decision in the mechanical change of sections of pipes does not give an opportunity exactly and operatively to influence on a technological process. The analysis of choice and use of facilities of automation is conducted in the article, and also modern control system by technological processes, with примененим of pipeline armature on the base of electro-pneumatic позиционеров of "Камоцци" with realization of feed-back by means of contactless proportional pick-ups of position with a current exit. The considered decisions allow not only clearly to support necessary office hours but also to change made decision at sharp rejections in-process control system. Results are got on determination of optimal values of sections of pipelines on the different technological areas of sugar-houses, necessary for maintenance of technological regime parameters of products (juice, syrup, limewater etc.), expense of steam and water. Research results give an opportunity to use , positioning of actuators for control.
