Description
Technical field
The present invention relates to the preparation method technical fields of coating, and in particular to a kind of flame retardant type for desulfurization inner wall of tower is anti-
Rotten wear-resistant coating.
Background technique
The energy resource structure in China is rich coal, few oil, lean gas, and coal is the long-term main energy sources in China, therefore Coal-fired Thermal Power
Factory or heating boiler still occupy an important position in national economy from now on.As national energy conservation and emission reduction strategy deeply promotes,
The implementation that coal fired thermal power plant or heating boiler will adapt to national energy conservation and emission reduction strategic objective will carry out sulfide in flue gas depth
Purification, current main sulfur removal technology is Limestone-gypsum Wet Flue Gas Desulfurization Process, is needed in process system using a large amount of preserving timber
Material.And requirement of the different processing steps to anti-corrosion material respectively has at anti-corrosion (acidproof, alkaline-resisting), wear-resisting, heatproof and fire-retardant aspect
Stress.The domestic anti-corrosion material in desulphurization system can not meet above-mentioned requirements simultaneously at present, and be mainly reflected in heatproof and resistance
Combustion aspect.
Flue gas also has a small amount of sulfur trioxide after desulfurization, and remaining sulfur trioxide is easy in the humidity in flue gas
Flue gas in dissolve, formed the very strong dilute sulfuric acid solution of corrosivity.Currently, the material for resistance to acid liquid corrosion has very much.But by
There is a large amount of flow at high speed flue gas in desulfurizer operational process, and have granular solid matter, to erosion resistant coating
Wash away, wear quite serious, conventional erosion resistant coating generally will be washed within several days it is thinned, soon perforation leak, cause
Desulphurization system it is out of service.
There are larger security risks for used glass flake anti-corrosion in the prior art, at present glass squama used in us
It is inflammable that piece meets fire, causes crushing loss, many desulfurizing towers have occurred for China various regions because of the great peace of fire caused by anti-corrosion at present
Full accident, this technology is used as anti-corrosion material using novel highly corrosion resistant ceramics organic coating, with nonflammable characteristic, from basic
On solve the problems, such as because of anticorrosive construction caused by fire incident.And long construction period, working security cannot be guaranteed.
