Abstract
The Relevance of the study is to develop a pilot industrial model of an anti-scale device using the principle of ultrasonic technology to prevent scale formation, based on the complex physical impact of mechanical vibrations on the liquid and the surface of pipes, by superimposing high-intensity sound vibrations on the vibrations of the ultrasonic frequency.
The Purpose. To experimentally evaluate the efficiency of a complex method of ultrasonic removal of scale deposits from the inner walls of heat exchange pipes. To consider the possibility of increasing the service life of heat exchange boilers by improving the quality of scale deposit removal from the surfaces of heat exchange pipes using ultrasonic and sound vibrations.
Methods. Practical experiments and evaluation of the effectiveness of the integrated method of ultrasonic removal of scale deposits were carried out on a pilot –industrial model of an anti-scale device mounted on a steam boiler of a boiler house.
Results. The article describes the relevance of the topic, considers the features of the developed anti-scale device and the features of its installation on the elements of the boiler heat exchanger. An experimental assessment of the effectiveness of the method of ultrasonic removal of scale deposits from the inner walls of heat exchange pipes is considered. Conclusions are made about the effectiveness of the claimed method.
Conclusion. The developed pilot-industrial anti-scale device uses the complex effect of mechanical vibrations on the liquid and the surface of pipes, which increases the effectiveness of the action to prevent and remove solid deposits from the heat exchanger. The positive effect of cleaning the internal surfaces of the heat exchanger has been established experimentally. The results obtained allow us to predict the possibility of increasing the service life of heat exchange boilers.
