[0002] The tunnel furnace is an industrial equipment with the characteristics of high temperature, high humidity and high corrosion, so the surface thereof needs to be coated with anticorrosive paint, and the paint is usually a high-temperature-resistant coating. In addition to the coating before assembly, the surface of the inner wall of the tunnel furnace also needs to be coated with anticorrosive paint again during maintenance to prolong the service life of the original anticorrosive coating in the tunnel furnace.

[0003] During the anticorrosive coating during maintenance, the surface of the tunnel furnace usually needs to be coated manually. The outer surface of the tunnel furnace is easy to coat because it is exposed to the outside, but it is not easy for the traditional manual brushing to enter the tunnel furnace due to the long length and small internal space of the tunnel furnace, which is not conducive to the anticorrosive coating of the inner surface of the tunnel furnace. In addition, when coating the anticorrosive layer on the surface of the tunnel furnace, a spraying method is usually used. During the spraying process, the paint is atomized into fine particles, and the atomized paint is easy to float out of the tunnel furnace through the flow of air in the furnace. If the atomized paint that floats out is not treated in time, it will cause environmental pollution and is not environmentally friendly. SUMMARY
