Abstract

The invention provides an efficient ultrasonic scale-preventing / removing device for a long-pipeline, which is used for removing / preventing scale in a conveying pipeline. The efficient ultrasonic scale-preventing / removing device comprises a power pulse signal control mechanism and a plurality of executing mechanisms connected to the pipeline, wherein the power pulse signal control mechanism is electrically connected with the executing mechanisms through cables; each executing mechanism further comprises a plurality of transducers which are inserted into a varying pipe in a uniform ring array mode, the inside of the transducers is isolated from mediums in the pipeline through a liner pipeline and the liner pipeline has same strength with the original pipeline, the outsides of the transducers are combined and fixed by a pretightening force, and the transducers are electrically connected with the power pulse signal control mechanism through cables. According to the efficient ultrasonic scale-preventing / removing device for the long-pipeline, obvious scale-removing effect of the long-pipeline can be realized, the scale is prevented from forming, dissolved oxygen in water can be prevented from corroding metal, the resistance is reduced and the flowing speed is increased.

Description

technical field

[0001] The invention relates to the field of anti-scaling / scaling-removing ultrasonic pipelines, in particular to an efficient ultrasonic anti-scaling / scaling-removing device for long pipelines. Background technique

[0002] In the field of pipeline transportation, pipelines are mainly used to transport the substances to be transported to designated places, but there are usually the following problems, for example: in oil pipelines, due to temperature changes during oil transportation, wax in oil gradually precipitates and deposits On the pipe wall, resulting in increased resistance, which affects oil transportation in severe cases; in the ash removal water return pipeline of a power plant, the ash flushing water is reused, and the scaling problem is very serious, and even affects safe production; In the pipeline, ice blockage is prone to occur, thus causing serious safety accidents. Therefore, how to solve the serious problem of fouling (wax deposition) bec...
