Automated control system of technological process of dust-gas cleaning after sintering machine (APSC)
The system is divided into two levels and is an integrated system under the hierarchical principle.
Lower level:
– process parameters control subsystem;
– technological equipment control subsystem;
– electric drives control manual buttons.
Upper level:
– the level of operational management of technological process, providing operational displaying and registration of information for creating an optimal connection interface between controller / operator and the system to allow a reliable assessment of the process.
APCS (top-level) is based on advanced software and hardware technologies for the collection, processing, transmission, archiving and visualization of operational data and functioning 365 days a year.
APCS (top-level) functions are implemented on Siemens S7 series controller and include two working automated workplaces on which is possible to register current process data. Operator workstation Software (SW) is built on the basis of the Siemens WinCC software. The system operation algorithm provides the following: Starting of dust cleaning equipment; stopping of dust cleaning equipment; emergency stopping of dust cleaning equipment;
– reagent dosing to ensure the effective implementation of the desulfurization process;
– exhaustion control in the shelter of the sintering machine;
– Temperature control over the path before the bag filter №1 – temperature control in the adsorber;
-providing of control valves operation.
