External set type ultrasonic fluid treatment device

Abstract

An external ultrasonic fluid processing unit has an external tube and an ultrasonic transducer disposed outside the external tube. The ultrasonic transducer has an ultrasonic transmitting end, whose transmitting direction is towards the inside of the external tube. On outer wall of the external pipe is disposed a tube wall invagination capable of invaginating towards the direction of the external tube cavity and setting at the above ultrasonic transmitting end. Between the above tube wall invagination and the ultrasonic transmitting end there is a glue line, which is used for gluing the tube wall invagination and the ultrasonic transmitting end together.

Description

Technical field [0001] The invention relates to an ultrasonic fluid processing device applied to pipelines. Background technique [0002] In order to achieve the purpose of anti-fouling or fluid viscosity reduction, dispersion, cleaning and other purposes in the pipeline, ultrasonic treatment technology is now usually used, that is, an ultrasonic transducer is installed in or outside the pipeline, and the energy emitted by ultrasonic is used to act on the inner wall or fluid of the pipeline. , Thereby avoiding fouling on the inner wall of the pipe or promoting fluid flow. For example, the applicant disclosed an ultrasonic anti-fouling device in Chinese Utility Model Patent No. 02244602.8, which is composed of an outer tube and an ultrasonic transducer. Two ends of the outer tube are provided with a pipe connection structure. The ultrasonic transducer The ultrasonic transducer is fixed in the outer tube, and the ultrasonic transducer has a transducer power connector extending outs...

AI Technical Summary

Problems solved by technology

For example, it can be seen from the accompanying drawings of the patent specification that in this product, the transducer is arranged in the concave pipe section of the outer wall of the pipe, and the inner wall of the pipe corresponding to the concave pipe section also protrudes toward the inside of the pipe. As a result, the inner diameter of the pipe will shrink, and the inner wall of the pipe will change in a staggered concave-convex shape, which will increase the fluid resistance and reduce the flow area, which is not conducive to the transportation of fluid.

[0004] After careful analysis, it is not difficult to find that for high-pressure pipelines with small diameters (below 300 mm), it is not suitable to install ultrasonic transducers inside the pipelines, and it is not easy to install ultrasonic transducers directly. set outside the pipe

This is because, in order to withstand higher liquid pressure, the pipe wall of the high-pressure pipe cannot be too thin, that is, the pipe wall of the high-pressure pipe is usually thicker. If the ultrasonic transducer is simply placed directly outside the pipe, the ultrasonic transducer will Most of the emitted energy will be reflected back by the thicker pipe wall, thus affecting the processing efficiency of ultrasonic waves

From this point of view, the technical solution disclosed in the above-mentioned Chinese Utility Model No. 00214308.9 cannot be directly applied to high-pressure pipelines

[0005] Therefore, for a high-pressure pipeline with a thicker wall, neither the ultrasonic transducer can be placed inside the pipeline, nor can the ultrasonic transducer be simply placed outside the thicker pipeline, thus forming a technical challenge
