AI Technical Summary

Technical Problem

During use, existing crude oil heating heat exchangers suffer from fouling due to the poor fluidity of crude oil, leading to deterioration of heat transfer and reduced unit efficiency. Furthermore, existing monitoring methods have a high rate of misjudgment.

Method used

Temperature sensors are used to detect temperature differences, and ultrasonic and infrared thermal imagers are used to monitor fouling. A three-dimensional model of fouling thickness and deposition rate is established through a multi-parameter fusion algorithm to achieve accurate monitoring of fouling inside the heat exchanger.

Benefits of technology

This improves the accuracy of fouling monitoring inside the heat exchanger, provides timely alarms to remind users to clean, reduces false alarms, and ensures the efficient operation of the heat exchanger.

Abstract

本实用新型涉及换热器污垢监测技术领域,具体的说是一种用于原油加热换热器污垢在线监测装置,包括换热器主体,所述换热器主体外部顶端螺丝固定有热源入口管;当要对换热器主体内的污垢监测时,支撑架外部螺栓连接的超声波发生器通过多组导线和探头对换热器主体内部发出超声波信号,然后利用污垢沉积导致的声阻抗变化,对换热器内的污泥进行监测,随后移动架带动红外热像仪通过观测窗对换热器主体内实时捕捉换热面温度分布异常,同时换热器主体内壁多组电阻传感器,监测污垢导电性变化,随后控制器将多组数据通过多参数融合算法建立污垢厚度、热阻与沉积速率的三维模型,提高对换热器主体内污垢监测的精度。
