摘要
把石化行业重点装置换热设备的清洗分为主动清洗和被动清洗。应用积分函数建立换热设备在使用寿命期内的总成本模型,将主动清洗开始时间看作随机变量,基于逐步增加步长的思路设计用于求解总成本模型的算法,目标是在总成本模型基础上求解最佳主动清洗开始时间和总成本最优值,还可根据总成本随主动清洗开始时间位于不同区域时的实时取值绘制总成本变化趋势图。
Both active and passive cleaning constitutes the heat exchanger cleaning in petrochemical industry.Making use of the integral function to establish total cost model of the exchanger was conducted,in which,taking the starting time of active cleaning as the random variable and basing on the idea of gradually-increasing steps,an algorithm for the total cost model was designed to solve the best active cleaning＇s start time and the optimal value of the total cost,and to draw total cost＇s trend chart according to the real-time value of the active cleaning＇s start time in different areas.
