摘要
传热设备的积垢问题一直是人们急于解决的的一大难题，不仅影响热能利用和生产正常运转，而且会降低产品质量，增加生产成本。通过机理研究、室内试验和工厂试验，揭示了超声波防除积垢的机理，筛选出最佳的声场参数，研制出一种新型的超声波防除积垢设备。室内试验和工厂试验结果表明，超声波技术不但可以防止新垢的产生，而且可以有效地除去已有积垢，显著地提高蒸发系统传热系数和生产能力，可停止使用化学清洗剂，从而延长传热设备使用寿命，避免污染环境。该技术有可能广泛地应用于制糖工业、化肥工业、制浆造纸工业等诸多领域。
Sca1e deposition on the heat transfer equipment (THE) is a difficulty prob- lem, it affects not only the utilization of thermal energy and normal run of production, but also the quality of product and production cost. After studying the mechaism, doing lab experiments and factory-scale experiments of scale control by ultrasonic wave, the mechanism was revealed and ultrasoinc parameters were optimized. In addition, a new type of ultrasonic equlpment was developed, which could remove scale siedcantly, as shown in the results of experiments done in a lab and a factory The experiments also indicated that this technique could prohibit the formation of new scale besides removing old scale, and improve heat transfer coefficielits and production capacity Furthermore, with this tecdrique, chemical detergents were not necessary to remove scale so that the HTE could be used for a longer time without chemical contarmination to environment. This new technique of scale control by ultrasoinc wave might be applied in many fields such as sugar industry, fertilizer and paper-making industry.
