摘要:
分析了工业换热器的服役工况条件,研究了流动-传热环境下的铵盐结垢机制,明确了换热器管束内结垢的影响因素,着重探究了注水对铵盐结晶的影响。基于铵盐结垢形成机制,设计了一种基于模糊数学的换热器除垢自适应注水系统。该系统对来自温度变送器、压力变送器和流量变送器的换热器进出口温度、压力和流速信号进行误差分析,以三类信号的平均相对误差及其变化率作为模糊控制系统的输入量。采用模糊数学控制调节阀的阀门开度,实时调节不同服役工况下清洗铵盐垢物所需要的注水量,并采用该方法计算了某一实际工况下所需的注水量。该文设计的系统解决了间歇性注水盲目性和滞后性的弊端,且符合节能环保的理念。
Abstract:
The condition of industrial heat exchanger is analyzed, the scaling mechanism of ammonium salt in flow-heat transfer environment is studied, and the influencing factors of scaling in the tube bundle of heat exchanger are defined, especially the influence of water injection on ammonium salt crystallization. Based on the formation mechanism of ammonium salt scale, an adaptive water injection system for heat exchanger scale removal based on fuzzy mathematics is designed. The system performs error analysis on the temperature, pressure and flow rate signals at the inlet and outlet of the heat exchanger from the temperature transmitter, pressure transmitter and flow transmitter, and uses the average relative error of the three types of signals and their rate of change as the input of the fuzzy control system. The fuzzy mathematics is used to control the valve opening of each regulating valve and adjust the water injection required for cleaning ammonium salt scale in real time. The self-adaptive water injection of heat exchanger descaling under different service conditions is realized,and the amount of water injection required under a certain actual working condition is calculated. The disadvantage of intermittent water injection lag and blindness is solved, and it is consistent with the concept of energy saving and environmental protection.
