Abstract
The utility model discloses a corrosion-resistant lining for wet type flue gas desulphurizing and dedusting equipment, belongs to environment-friendly equipment, and particularly relates to wet type flue gas desulphurizing and dedusting equipment with a corrosion-resistant layer on an inner surface. The corrosion-resistant lining for the wet type flue gas desulphurizing and dedusting equipment is characterized by comprising a framework material, a paving cushion layer, a bonding layer and a surface corrosion-resistant layer, wherein the framework material consists of an inverse V-shaped fixed pile of which one end is welded on a housing of the equipment and a steel wire mesh fixed by the inverse V-shaped fixed pile, the paving cushion layer is an acid-resistant cement layer bonded on the housing of the equipment and wrapping the framework material, the bonding layer is a mixed layer of water glass and acid-resistant cement, and the surface corrosion-resistant layer is an acid-resistant ceramic tile bonded on the bonding layer. By adopting the structure that the acid-resistant cement is used as the paving cushion layer and is bonded with the acid-resistant ceramic tile on the surface, the corrosion-resistant lining has the advantages of being low in cost, high-temperature-resistant, wear-resistant, corrosion-resistant, low in corrosion-resistant cost, difficult to fall off, and easy to repair. After being used for the about ten years, the corrosion-resistant lining is proved to be good in effect, and has a service life of being more than ten years.
Description
Technical field
The utility model belongs to environmental protection equipment, particularly has the wet flue gas desulfurization and dust removal equipment of inner surface anticorrosive coat.
Background technology
The steel wet type desulfurizing dust collector has been brought into play enormous function in boiler, kiln gas desulfurization, for coal-fired flue-gas purifies the very big effect of having brought into play.But because in the wet type desulfurizing technology, the SO2 in the flue gas mixes formation acid water with alkaline water in the desulphurization plant, and humidity is higher, about about 40 ℃, this has accelerated the corrosivity of these acid waters greatly.Therefore it is important that the anticorrosion process of steel desulfurating dust-removing equipment causes the pass.Present anti-corrosion measure is the anticorrosion mode of glass flake mostly, but its anti-wear performance is poor.There is the occasion of flue dust wearing and tearing or desulphurizing and dust-removing integral not too to adapt to for some, all incompatible such as the small-sized desulphurizing and dust-removing integral equipment of desulfurizing tower gas approach section.The sulfur removal technology that has at present adopts glass-cermic powder or acid resistant adhesive mortar to handle.But the variability of heatproof degree is poor, is prone to produce be full of cracks simultaneously, uses for these equipment and brings certain influence.
The utility model content
For overcome existing corrosion-proof lining anti-wear performance poor, to the deficiency of difference variation bad adaptability; The utility model provides a kind of wet flue gas desulfurization and dust removal equipment corrosion resisting liner; Not only the acid-resistant anti-corrosion performance is good for this wet flue gas desulfurization and dust removal equipment corrosion resisting liner, and wear-resistant, influenced by difference variation little.
The utility model solves the technical scheme that its technical problem adopted: a kind of wet flue gas desulfurization and dust removal equipment corrosion resisting liner; It is characterized in that: comprise framework material, lay bed course, adhesive linkage, surface anticorrosion layer; Described framework material is welded on the reverse V-shaped spud pile on the apparatus casing by an end and is formed by the fixing steel wire of reverse V-shaped spud pile; The described bed course that lays is the acid-resistant cement layer that is bonded on the apparatus casing and wraps framework material; Described adhesive linkage is waterglass and acid-resistant cement mixed layer, and described surface anticorrosion layer is the acid-proof ceramics brick that is bonded on the adhesive linkage.
Described reverse V-shaped spud pile layout triangular in shape on the apparatus casing inner surface.
The beneficial effect of the utility model is that the employing acid-resistant cement is to lay the structure that mat surface is pasted the acid-proof ceramics brick.Its advantage is the low difficult drop-off of low, high temperature resistant, wear-resistant, corrosion-resistant, the anticorrosion cost of cost, is prone to repair.Use through nearly ten years proves that respond well, be in the interior corrosion-proof lining of present wet type desulfurizing equipment service life more than 10 years, comparatively desirable a kind of anticorrosion structure.
