摘要
通过池动态模拟实验,利用自动数据采集系统,以CaCO3污垢溶液为研究对象,配置了不同浓度的模拟溶液,在不同的污垢溶液浓度及热通量等工艺条件下引进了超声波清洗,以减小污垢在金属表面的沉积.跟踪系统不同点的温度,采用数学处理方法转换成传热系数,以此评价阻垢作用.研究表明,超声波清洗不仅明显强化了传热效果,也有效阻止了污垢在加热器表面的沉积,具有良好的抗垢作用.
Pool boiling in CaCO3 solution was performed to determine the heat transfer system through data acquisition system and dynamic experiments. Under the conditions of different CaCO3 concentrations and heat fluxes, the ultrasonic was introduced to test its effect on the fouling accumulation on the metal surface. The temperature measurements at the different points on the heating element were transformed to heat transfer coefficient, so that the fouling inhibition fimction can be evaluated. The results show that the ultrasonic not only enhanced the boiling heat transfer, but also prevented the formation of the fouling on the metal surface, very good fouling inhabiting performance being demonstrated.
