Description

Technical Field

[0001] The utility model relates to the technical field of anti-coating inside a tube bundle, in particular to a heat exchanger tube bundle dipping system. Background Art

[0002] Although the lengths of heat exchanger tube bundles vary, they all follow their own rules in terms of diameter and structure. The minimum diameter is 300 mm, and a new model is added for every 100 mm increase. Conventional models have diameters of 400 to 2,500 mm, and the overall structure is cylindrical. Regardless of the diameter of the heat exchanger tube bundle, it is composed of multiple small-diameter carbon steel pipes arranged in a certain pattern. In the existing anti-corrosion construction process, the existing process for internal tube anti-corrosion requires the coordination of three people: one person to open the valve, and two people to paint the workpiece. Six tubes are painted at a time. For example, a large piece of equipment requires three people to repeat the painting action hundreds or thousands of times. The existing process for external tube anti-corrosion also requires the coordination of three people: one person to open the valve, and two people to paint the workpiece. Two people start from one end of the workpiece and spray the outside to the other end. There are uncontrollable factors in the coordination, which poses great risks to environmental protection and safety. The labor intensity of workers is high, and the quality is uncontrollable, and it is easy to miss the paint. Therefore, an automated painting system is designed.
