Abstract

The invention belongs to the technical field of anti-corrosion materials, and particularly relates to a composite heavy anti-corrosion structure for a thermal power plant titanium plate chimney. The composite heavy anti-corrosion structure for the thermal power plant titanium plate chimney is arranged on a titanium plate chimney body, the titanium plate chimney body comprises multiple titanium plates which are welded together, a nano composite emulsion titanium plate substrate coating and at least one light curing fiber reinforcement composite layer, and the nano composite emulsion titanium plate substrate coating and the light curing fiber reinforcement composite layers are sequentially arranged on the welding seams of the multiple titanium plates and used for closing the welding seams. The composite heavy anti-corrosion titanium plate chimney has the advantages of being excellent in mechanical strength, high in electrical insulation and thermal insulation, high in temperature resistance, good in heat shock resistance, small in expansion coefficient and the like; chemosmosis can be well prevented, a base material is prevented from making contact with the outside world to the maximum extent, and the long-time stability of the base material is guaranteed; the construction time can be greatly shortened, and the construction difficulty and labor cost can be greatly lowered.

Description

technical field

[0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to a composite heavy-duty anti-corrosion structure and a heavy-duty anti-corrosion construction process for titanium plate chimneys of thermal power plants. Background technique

[0002] With the improvement of national environmental protection regulations and the increasing awareness of environmental protection, in order to reduce the air pollution caused by sulfur dioxide emissions, the flue gas produced by burning coal fuels in thermal power plants needs to be desulfurized. The flue gas after wet desulfurization contains high-temperature sulfur dioxide, sulfuric acid, sulfurous acid, hydrofluoric acid and various miscellaneous acids, which will cause serious corrosion to the inner wall of the chimney. Traditional heavy-duty anti-corrosion materials are due to their corrosion resistance, mechanical properties, and It is difficult to resist the harsh en...
