摘要
壳管式换热器是应用于工业生产和能源领域的重要设备之一。在使用过程中,换热器内部不可避免地会产生污垢,这些污垢会严重影响换热器的性能和使用寿命。因此,分析了污垢的形成机制,包括壳管式换热器中液体和气体两相流的流动特性及其对换热器内部壁面的沉积和结垢,从而探讨了污垢对壳管式换热器设计的影响因素。
Shell and tube heat exchangers are one of the important equipment widely used in industrial production and energy fields.During the use process,dirt inevitably occurs inside the heat exchanger,which can seriously affect the performance and service life of the heat exchanger.This article analyzes the formation mechanism of fouling,including the flow characteristics of liquid and gas two-phase flow in shell and tube heat exchangers,as well as its deposition and scaling on the internal wall surface of the heat exchanger,thereby exploring the factors that affect the design of shell and tube heat exchangers.
