Abstract

The invention provides an arc-shaped closed-structure heat exchanger for descaling with sound waves. The heat exchanger comprises an upper collecting pipe, a lower collecting pipe and an arc-shaped closed finned pipe connected with the upper collecting pipe and the lower collecting pipe, the heat exchanger comprises a descaling device, superaudio frequency pulse signals are sent by a main engine of an automatic scale prevention device and are converted by an energy converter to generate superaudio frequency pulse vibration, the superaudio frequency pulse vibration acts on water in the metal pipe of the energy converter, the superaudio frequency pulse vibration enables high-speed microflow and a cavitation effect to be generated between the metal pipe and the water, scales are prevented from being formed, heat exchanging resistance is reduced, heat exchange efficiency maximization is achieved to save energy, and the aim of environment protection and energy saving is achieved.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a heat exchanger with descaling function. Background technique [0002] Petrochemical, oil refining, steel, thermal power and many other enterprises use a large amount of cooling and circulating water for heat exchange in the production process. Heat exchangers and pipes connected to other devices, due to the presence of various acids, alkalis, salt ions and other organic impurities in the water, scales are easily formed on the inner walls of the heat exchangers under high heat conditions, and the scale layers accumulate thicker and thicker, making heat exchange difficult. Efficiency is greatly reduced, causing great waste of heat energy. In addition, fouling poses a serious threat to the safe production of heat exchangers. Therefore, the heat exchanger and piping must be descaled regularly. The commonly used method is manual or chemical cleaning. Chemical cleaning is to add ch...
