Description

Technical Field

[0001] The utility model relates to the technical field of coating surface treatment, in particular to a continuous rust removal device for an offshore platform. Background Art

[0002] Coating protection is the most commonly used external anti-corrosion method for offshore platforms. Affected by mechanical damage, coating defects and coating life, the coating needs to be repaired regularly. With the enhancement of environmental awareness, high-pressure water rust removal is gradually replacing manual grinding and sandblasting rust removal processes with its advantages of being green, environmentally friendly and dust-free, becoming the mainstream rust removal process for offshore platforms. However, traditional high-pressure water rust removal devices are large in size and need to be placed in a specific lifting position. High-pressure water is transported to the rust removal position through a very long delivery pipeline, and the pressure drop of high-pressure water is large during the transportation process. High-pressure water rust removal can cause varying degrees of flash rust on steel structures, affecting the quality of the coating. Therefore, it is necessary to add anti-flash rust agents to the water. Traditional high-pressure water rust removal devices require an external water supply pipeline for continuous water supply, and it is difficult to steadily and continuously add anti-flash rust agents to maintain a good surface treatment effect.
