Abstract: Addressing current challenges of low efficiency in removing microorganisms through chemical addition in spray pools of converter stations, heavy workload for personnel and a lack of intelligent means, in order to ensure that spray water meets standard requirements of valve cooling system in real time, firstly, composition of converter valve water cooling system and issues related to spray water dosing are analyzed. Secondly, an intelligent dosing system specifically designed for spray pools is developed, focusing on its functions, overall structure, system unit modules and communication methods. Finally, intelligent dosing strategy of designed system is studied and compared with existing dosing schemes. The designed dosing system is highly efficient, real-time, precise in controlling the dosage, minimally affected by human factors and highly intelligent. It has significant engineering application value in reducing dosing costs, saving operation and maintenance time and providing real-time control of on-site operating status across multiple terminals.
