氧化铝蒸发工序用能分析及系统优化节能研究
Research of energy saving optimization system for alumina production evaporation process based on thermal analysis
摘要
Abstract
A energy analyzing model was developed by using exergy method, and the energy consumption level was evaluated according to exergy efficiency and other indexes. Based on“Three part”energy system optimization theory,an optimization scheme of preheating ore pulp with recycled waste heat was proposed. Energy consumption models for the evaporation systems before and after optimization were developed, and optimization computations were made. The results show that increasing ore pulp temperature at inlet of evaporator process can effectively reduce the amount of consumed new vapour and therefore improve the energy utilization level of the evaporation process.关键词
