Description
Technical field
The utility model belongs to chimney anticorrosion field, particularly relates to the anticorrosion impervious field of chimney of electric plant, specifically, the present invention relates to the anticorrosion impermeabilisation inner lining body of a kind of novel chimney.
Technical background
In order to meet the needs of China's Green Development, day by day improve for the environmental protection standard produced, newly-built thermal power plant all must carry out the desulfurization of flue gas chimney anticorrosion, thus in requisition for reduction sulfur dioxide (SO2) emissions total amount.Substantially all lime stone is adopted, the Wet Flue Gas Desulfurization Techniques such as gypsum at present in China's coal unit desulfurization.The carrier of this technology is water and lime stone, containing a large amount of steam and sulfur dioxide in flue gas after desulfurization, in flue gas uphill process, inner wall of stack there will be dew condensation phenomenon, thus form condensate water at flue and chimney inside, belong to high humidity diluted acid type corrosive liquid, Main Ingredients and Appearance is wherein exactly sulfuric acid, hydrochloric acid and other etchant gas liquid, cause corrosion to chimney concrete tube wall, therefore the saturating treatment measures of the anti-corrosion leak-proof of chimney just seem very important.And, in the process of flue gas discharge, flow through impact that the high-temperature gas of flue and dust cause for inner wall of stack and wearing and tearing are also very serious.Therefore, not only require that inner wall of stack can tolerate the corrosion of contained corrosive component in the high temperature of flue gas, resistance to flue gas, and requirement can prevent Liquid Penetrant and the overcoat that may cause thus from peeling off, and require that the overcoat directly contacted with flue gas is high temperature resistant and wear-resisting.So select the inner wall of stack protection be applicable to, it is vital for running economically for power plant safety.
Many chimneys of prior art are many only concentrates on the Anticorrosion solving chimney, the infiltration problem that the high-load steam brought for wet desulfurizing process causes and the spallation problems not good solution that the overcoat caused thus causes.
For the problems referred to above, the utility model provides the anticorrosion impermeabilisation inner lining body of a kind of Novel chimney, not only can prevent inner wall of stack from corroding well, and solves impermeable and overcoat spallation problems well, and has better heat resistant and wear resistant.
Utility model content
Of the present utility modelly provide the anticorrosion impermeabilisation inner lining body of a kind of novel chimney, object be to solve current chimney of electric plant to the problem such as high temperature resistant, corrosion-resistant, impermeable and wear-resistant.
The purpose of this utility model realizes by following technical solution:
The anticorrosion impermeabilisation inner lining body of a kind of chimney, puts on chimney body inwall, it is characterized in that: described inner lining body comprises successively from inside to outside from inner wall of stack: the impervious layer of primary coat, polymer repair layer, adhesive layer and brick layer.
Chimney lining layer of the present utility model can optionally such as spray to wait in a suitable manner as required and apply surface protecting layer in described brick layer, to provide the performances such as better wearability, impervious corrosion resistance and optional radiation proof, its thickness is about 0.01mm-0.01mm.
The impervious layer of described primary coat is applied on inner wall of stack, and thickness is about 0.05mm-0.20mm, is preferably about 0.08mm-0.12mm.The impervious layer of described primary coat such as can be brushed by the applicable mode of this area routine, roller coating, spraying etc. or other any applicable method are constructed.
Described polymer repair layer is positioned on described impervious priming coat, be made up of heat-resistant polymer, play the effect of the sealing of chemicals-resistant burn into, impermeabilisation, its thickness is about 0.5mm-4mm, preferably approximately 1mm-3mm, described polymeric layer can be applied on priming coat by the painting method of routine well known by persons skilled in the art or other any applicable method.
Described adhesive layer, between polymer repair layer and brick layer, is made up of the glue with fabulous close-burning high temperature resistant chemicals-resistant, and its thickness can be about 1.0mm-4.0mm, preferably approximately 2mm-3mm.Described adhesive layer such as can be applied by blade coating or brushing.
The brick of described brick layer is made up of exotic material, and described brick can be such as foam glass brick and vitreous ceramic brick, and have very excellent wear resistant heat preserving effect, its thickness is approximately 40mm-60mm, such as about 50mm.
The beneficial effects of the utility model are: compared with prior art, chimney lining body of the present utility model not only has better chemicals-resistant corrosivity and resistance to elevated temperatures, and effectively prevent the overcoat that water vapor permeable in production process causes and peel off, the impact simultaneously caused for flue gas and the dust of flowing and wearing and tearing have better anti-pressure ability and mar proof, still can keep excellent performance in temperature difference alternate environment.The utility model substantially prolongs the service life of chimney, and, easy and simple to handle, short construction period, thus greatly reduce anticorrosion cost, be very beneficial for production economy and run safely.
