Abstract


Guaranteeing the high grade of sulfuric-acid and conserving system energy have very important meaning to the long-term development of smelter off-gases sulfuric-acid making industry in our country.This thesis chooses smelter off-gases sulfuric-acid making system in Shaoguan Smelter as research object, through system testing and diagnosing analyze its problem, find out that the reason why system can not produce 98% sulfuric-acid in summer is that the entry smoke temperature of drying tower is so high because of the high ambient temperature, with high moisture content of smoke, leading to increasing of water content and heat emission amount, so the standard sulfuric-aid can not be produced. In order to solve this problem, basing on the afterheat resource testing and analysis of hot stove, we studied out a solving method that using the afterheat resource to provide power for a bromine refrigeration as to reduce the smoke temperature. This method is the first case in China, and is already adopted by Smelter.Borrow the experience of pinch point technology using in petrochemical Company, and through further analyzing the system energy conservation ability with pinch point technology, it comes out the result that through reducing entry water temperature of weak acid cooler, the cold utility provided by fan and cooling tower in water cooling system can be saved about 8761.36kW,. The conserved energy converted to power consumptions are 108.58kW, some refrigeration equipment can be saved. This provides practical meaning to the system energy conservation of corporation, and has theory meaning to the energy conversation and optimization designing in off-gases sulfuric-acid making technology.
