Abstract:The circulating water system of the furnace body supplies cooling water to the industrial furnaces and kilns as well as air blowers in the smelter. As the key auxiliary process of the smelter, this system’s safety and reliability is closely related to the safe and stable operation of the furnaces and kilns. At present, the water pump room of the smelter is often only equipped with conventional detection devices such as liguid level, flow and metor current detection devices, which maily depends on manual inspection, so that there is a large demand for manpower and a lot of maintenace work. Therefore, the circulating water system of the furnace body demands upgrading and transformation for intelligentization and unattended operation. This paper introduced the frome of unattended circulating water system, and discusses the integrated design of unattended circulating water system from the aspects of intelligent upgrading of power supply and distribution, upgrading of detection and automation, as well as green & energy conservation. The unmanned furnace circulating water system should set up a complete sensing detection component and control system. The equipment body, signal detection and perception, power supply and distribution, and process control should be organically integrated to realize the effective integration of intelligent perception, production control, equipment health status assessment and pre-maintenance.
