Abstract

The utility model relates to the technical field of anti-corrosion fluid distributors, in particular to an anti-corrosion fluid distributor device of an off-peak electricity heat storage and supply system, which comprises a distributor body, reinforcing ribs, an anti-corrosion mechanism and a monitoring module. The utility model has the following advantages: the nano material layer adopts a multilayer structure of the epoxy primer layer, the nano ceramic middle layer and the polyurethane surface layer, so that multilayer composite protection is realized, and the problem that the traditional epoxy resin coating is easy to peel off at high temperature is solved; the corrosion-absorbing elastic metal layer (such as active metal as zinc, aluminum and the like) embedded in the retention pipe can preferentially react with corrosive ions in fluid according to the electrochemical corrosion principle, the corrosion-absorbing elastic metal layer is consumed to protect metal of the distributor body, and meanwhile, the elastic material can adapt to fluid impact and temperature deformation, so that cracking of the protective layer is avoided.
