Abstract


Zinc distillation process from the melting furnace , liquid crude zinc added to the lead column in the flow of this process is a key technical parameters . The crude zinc liquid flow is stable or not , is one of the most important factors that affect distillation column life , and zinc product yield and quality . The liquid zinc due to the high temperature and corrosive and small flow , at home and abroad have not yet online detection of this parameter . Papers on the basis of in-depth understanding of the distillation process , the proposed detection method based on soft measurement techniques - weighing method detection parameters , it is the weight of the crude liquid zinc as fluid dynamics in the orifice flow theory basis for the establishment of the mathematical model between traffic and weight in order to achieve the indirect measurement of the flow , to solve the problems of the crude zinc liquid flow can not be measured . In complete zinc liquid flow detection based on the control of the flow of liquid zinc . The paper gives the structure of the control system , the concrete realization process , process control host computer based production scheduling output flow settings the lower machine (PLC) based on the setting of the host computer controlled stepper motor , adjust the feed valve opening with a dead zone integral separation PID control algorithm the zinc liquid flow stability control . The same time, a set of monitoring and management software with VC design production site data monitoring and management of the operating personnel . The entire system has been put into use in the field , running results show that the system is reliable to address the corrosive high temperature small flow of liquid flow control problems , bring great economic benefits to the enterprise .
