Descaling tool, descaling device and descaling method for pipe

Abstract

The invention provides a descaling tool for a pipe, which comprises a tool main body. The main body comprises a cylindrical cutting part and a connecting part which axially stretches from the cutting part, wherein the cutting part is provided with a plurality of spiral grooves which are uniformly distributed on the external circumferential surface of the cutting part around a central axis of the cutting part. The invention further provides a descaling device for the pipe, which comprises a driver and the descaling tool, wherein the driver is provided with a drive shaft, the descaling tool is the descaling tool provided by the invention, and the descaling tool is connected with the drive shaft. A descaling method for the pipe comprises the following steps: a) placing the descaling tool into the pipe; and b) driving the descaling tool to rotate and move linearly in the pipe. The descaling tool, the descaling device and the descaling method provided by the invention can fully avoid the problem of corrosion on the pipe and achieve higher descaling efficiency.

Description

technical field [0001] The invention relates to the field of pipeline dredging, and more specifically relates to a tool, device and method for removing fouling in pipelines. Background technique [0002] Pipes are commonly used components in industrial equipment, especially in chemical equipment, and are usually used to transport various materials, such as liquids, gases or slurry substances. [0003] For example, in a heat exchanger, a heat transfer medium is usually made to flow in the heat exchange pipes of the heat exchanger, thereby exchanging heat. For example, in the field of generators, a hydrogen cooler is usually provided to prevent the components in the generator from overheating. Specifically, during the operation of the generator, the stator coil will generate a large amount of heat, and the hydrogen with a lower temperature absorbs the heat and becomes hydrogen with a higher temperature, and then the hydrogen with a higher temperature is sent to the hydrogen c...

Problems solved by technology

[0007] However, the disadvantage of this traditional descaling method is that the chemicals used for descaling are usually corrosive, so the pipeline will be damaged while descaling Corrosion itself will not only shorten the service life of the pipeline, but also cause damage to the pipeline in severe cases (for hydrogen coolers, if the pipeline is damaged, it will cause hydrogen leakage, which seriously threatens safe production); When descaling, it is necessary to stop the operation of the generator, and the chemical reaction between scaling and chemical agents needs to be carried out for enough time to achieve the desired purpose, so the traditional method of using chemical agents for descaling treatment is relatively inefficient
