Ultrasonic on-line anti-scaling and descaling system for heat-exchange device

Abstract

The invention relates to an ultrasonic on-line anti-scaling and descaling system for a heat-exchange device. The ultrasonic on-line anti-scaling and descaling system for the heat-exchange device comprises an ultrasonic sounding unit and an energy converter electrically connected with the ultrasonic sounding unit. The ultrasonic sounding unit comprises an adjusting and controlling unit. The adjusting and controlling unit performs directional design and adjusting on ultrasonic acoustic parameters according to ultrasonic attenuation information inside a pipeline which is fed back through an ultrasonic signal feedback unit. Compared with the prior art, the ultrasonic on-line anti-scaling and descaling system can perform adaptive adjustment on the ultrasonic acoustic parameters according to different application environments, so that effective and sufficient antiscale and descaling can be performed under different pipeline environments of the heat-exchange devices of different types.

Description

technical field [0001] The invention relates to the field of anti-scaling and descaling of ultrasonic pipelines, in particular to an ultrasonic on-line anti-scaling and descaling system for heat exchange equipment. Background technique [0002] There are more than 300,000 heat exchange equipment in my country's petrochemical industry. For a long time, there has been no good solution to the problem of scale prevention and descaling of these equipment. Heat exchange equipment generally operates under the state of scale with a thickness of 0.2-10mm. The thermal conductivity of scale (generally around 1W / m·K) is only a few tenths of that of the metal tube wall of the heat exchanger. According to industry statistics, the annual deposition thickness of scale in heat exchange equipment and pipelines is about 4mm. For every 1mm increase in heat exchange equipment fouling, the heat transfer coefficient will decrease by 9% to 9.6%, and energy consumption and emissions will increase by...
