Background

In a thermal power station, a boiler is necessary equipment, the cleaning inspection of a pipeline on a heating surface of the boiler is concerned about the operation safety of the power station, if foreign matters in the pipeline are blocked, the efficiency of the power station is influenced slightly, and the phenomenon of tube explosion or even boiler explosion is caused seriously, so that the safety and the economical efficiency of the stable operation of the power station are seriously damaged.

In the prior art, aiming at cleaning inspection of a pipeline on a heating surface of a boiler, a conventional method is to perform a ball passing test on the pipeline, namely steel balls with corresponding ball diameters are used for completing the test of moving from one side of the pipeline to the other side under the thrust of compressed air, and if the steel balls pass through the pipeline smoothly, the inside of the pipeline is clean and the later operation is not influenced; if the steel ball is blocked in the pipeline, taking out the steel ball and the sundries by adopting corresponding measures, and carrying out the ball passing test again.

The detection method mainly has two problems, one is that the detection test requires to be carried out one by one after the heated surface pipeline is transported to the site, time and labor are wasted, the exact position of the sundries cannot be judged even after the sundries block the test ball in the pipeline, and the sundries are taken out by a compressed air machine or even a large-sized crane, so that a large amount of time is consumed, and a large amount of cost is increased. On the other hand, the steel balls for the test are blown to the other side from one side of the pipeline by using compressed air to ensure that no sundries are blocked in the pipeline, personnel need to be arranged on two sides to complete the ball serving and receiving work, and in order to ensure that the steel balls pass through smoothly, the compressed air needs to supply feet, so that the condition that the steel balls are stressed to damage ball receivers can be caused, and even the steel balls are not received and directly blown to other external areas to damage people or objects.
