摘要:

为研究换热设备生物污垢的形成过程,将Capdeville生物膜增长体系引入Kern-Seaton模型,建立了一个新的微生物污垢模型。采用铁细菌和管式换热装置对模型进行了实验验证。结果表明:除诱导期外,新建的微生物污垢热阻模型的计算数据和实验数据的相对误差小于20%。

关键词: 微生物污垢, 污垢模型, Capdeville生物膜增长体系, 冷却水

Abstract:

In order to study biofouling process in heat exchangers, a new microbial fouling model was established by introducing the Capdeville biofilm growth system into the Kern-Seaton model. The new model was verified by experiments of the iron bacteria growth in tubular heat exchangers. Less than 20% relative error was achieved between the model prediction and the experimental data regardless of the induction period.

Key words: microbial fouling, fouling model, Capdeville biofilm growth system, cooling water
