Reinforced concrete wall of a chimney body of the single-tube chimney is inwardly provided with the fast-drying mortar repair layer, the heat-resistant antioxidant anticorrosive coating layer, the acid-proof heat-resistant silicone rubber adhesive layer and the lightweight vitrified acid-proof ceramic tile layer in sequence. A lining interface of each section of the single-tube chimney is provided with a slope layer, and an acid-proof heat-resistant silicone rubber adhesive layer is arranged in the slope layer. The wet desulphurization anti-corrosion system of the improved single-tube chimney of the thermal power plant is an economical, practical, convenient and novel anti-corrosion system which is utilized for improving a single-tube chimney of the thermal power plant; due to the fact that the acid-proof heat-resistant silicone rubber adhesive layer and the lightweight vitrified acid-proof ceramic tile layer are utilized in the anti-corrosion system, the wet desulphurization anti-corrosion system of the improved single-tube chimney of the thermal power plant achieves the functions such as anti-acid corrosion, abrasion resistance and heat preservation; and the wet desulphurization anti-corrosion system of the improved single-tube chimney of the thermal power plant has the advantages of being convenient to implement, good in anti-corrosion property, good in durability, and the like.
Description
Technical field
The utility model relates to the corrosion protection system that the wet desulphurization of monotubular chimney is transformed in a kind of thermal power plant.
Background technology
Enhancing along with public's environmental consciousness; National policy is also increasingly high to the requirement in the environmental protection; Thermal power plant as environmental protection key monitoring object stands in the breach especially, and environmental protection thermal power plant not up to standard just need be transformed, and flue gas is carried out discharging after desulfurization is handled again.Flue gas after the desulfurization is a wet flue gas; The corrosion type of its desulfurization wet flue gas comprises sulfuric acid, sulfurous acid, chloride, fluoride etc.; The flue gas grade is a severe corrosive, and low, the high humidity, little from pull out force of this cigarette temperature almost is in full operation under positive pressure state according to the theoretical calculation chimney.The condensate that the desulfurization smoke condensation forms has very strong corrosivity, and concrete chimney is worked under sour environment, corroded by the double action of flue gas pressures and humidity, has a strong impact on chimney safe handling and structure durability.The utility model patent has proposed a kind of economical and practical, novel easily chimney anticorrosion way of enforcement in transforming the chimney process.
The utility model content
The utility model technical problem to be solved provides the corrosion protection system that the wet desulphurization of monotubular chimney is transformed in a kind of thermal power plant, efficiently solves the anticorrosion problem of chimney.
The utility model technical problem to be solved realizes through following technical scheme:
