Abstract

Fouling is inevitable on the surfaces of industrial equipment, especially on heat-exchanging surfaces in contact with ﬂuids, which causes water pollution and destroys the ecological environment. In this paper, a novel fouling-removal methodology for plate structure based on cavitation by multi-frequency ultrasonic guided waves is proposed, which can remove fouling on stainless steel plates. A numerical simulation method has been developed to study the acoustic pressure distribution on a steel plate. According to the simulation results, the distribution of sound pressure on the plate under triple-frequency excitation is denser and more prone to cavitation than in single-frequency cases and dual-frequency cases, which improves fouling removal rate. The stainless steel plate is immersed in water for the descaling experiment, and the results show that the fouling removal rates of three water-loaded stainless steel plates under diﬀerent single-frequency excitation seem unsatisfactory. However, the multi-frequency excitation improves the descaling performance and the removal rate of fouling reaches 80%. This new method can be applied to the surface descaling of large equipment plates, which is of great signiﬁcance for purifying water quality and protecting the ecological environment

基于多频环保超声波导波技术的钢板表面污垢去除技术

工业设备表面，尤其是与液体接触的热交换表面不可避免地会产生污垢，造成水污染，破坏生态环境。本文提出了一种基于多频超声导波空化作用的新型板结构污垢去除方法，可去除不锈钢板上的污垢。建立了一种数值模拟方法来研究钢板上的声压分布。模拟结果表明，在三频激励下，钢板上的声压分布更密集，比单频和双频情况下更容易产生空化，从而提高了污垢去除率。将不锈钢板浸入水中进行除垢实验，结果表明，在不同的单频激励下，三块装有水的不锈钢板的除垢率似乎并不理想。然而，多频激励改善了除垢性能，污垢去除率达到 80%。这种新方法可用于大型设备板材的表面除垢，对净化水质、保护生态环境具有重要意义。
