| Résumé : |
Total recycling of chromium-containing waste from tanning industry forms a compact technology that is aimed at solving the problem of the presence of chromium in both solid and liquid wastes generated during the leather manufacturing processes. If the technology is to provide a compact system usable in industrial practice it is necessary to provide a complex control based on advanced technical and software tools that enable the use of modern automatic control methods. For that purpose, a decentralized computer control system has been constructed in laboratory conditions at Tomas Bata University in ZlÃn, the properties of which allow its relatively easy transformation into industrial scale. The system consists of two main parts : a control system of the key technological processes-hydrolysis, filtration, evaporation, total de-chroming of both the filtration cake and spent liquor; and a superior central control unit which ensures supervision of the entire process. The control system is designed alternatively with respect to the use of various types of technical components and communication paths, which allows designing the final industrial system with the use of a selected automation and information technology. |
