In order to reach the inner wall of stack steel copper corrosion-resistant effect of steam power station, the general anti-corrosion method adopting of the inner wall of stack steel copper of the steam power station in prior art is mainly titanium plate, coating, foam glass brick and vitreous ceramic brick etc.But in these methods, 1. titanium plate price is extremely expensive, and china natural resources rareness, has limitation; 2. coating, the life-span is short, in 1-2, comes off with regard to large area, cannot use; 3. foam glass brick and vitreous ceramic brick fly brick phenomenon, dangerous, once and vitrified brick fly out, so just cannot be anticorrosion; Foam glass brick and vitreous ceramic brick are to adopt castable to be built into, and the anticorrosion time of castable is short, and cost is also very high.
Summary of the invention
High in order to overcome the inner wall of stack steel copper anti-corrosion measure cost of the steam power station in prior art, the shortcoming such as short and antiseptic effect of life-span is bad, a kind of corrosion-resistant Chimney in Fossil Power Plant inwall steel inner cylinder is provided, by utilizing high rotproofness board with enamel panel layer for Chimney in Fossil Power Plant inwall steel inner cylinder, reach corrosion-resistant object, adopt the areola that a 3-5cm is set in the middle of inner steel cylinder of chimney layer and glassed steel flaggy simultaneously, and squeeze into compressed air, utilize pressure differential to prevent that flue gas and steam from infiltrating the seam of board with enamel panel layer and board with enamel panel layer, effectively protect edge and the steel cylinder surface of enamelled pressed steel, reach and improve the chimney object in application life.
The technical scheme that the utility model is dealt with problems is as follows.A kind of corrosion-resistant Chimney in Fossil Power Plant inwall steel inner cylinder, outermost layer is layer of concrete, layer of concrete is inwardly directly connected with steel inner cylinder layer, steel inner cylinder layer inwardly arranges many U-shaped stainless steels and connects corner brace, as the enamel flaggy of liner, rectangle stainless steel square pipe holder is outwards set, the U-shaped stainless steel that enamel flaggy hangs over steel inner cylinder layer by rectangle stainless steel square pipe holder cover connects after connecting in corner brace to be fixed, high acidproof by utilizing high rotproofness board with enamel panel layer to have, alkaline resistance properties and surface have smooth exquisiteness, the advantages such as the wear-resisting and heat-resisting sudden turn of events, reach antiseptic effect.After being connected with the glassed steel flaggy of liner, steel inner cylinder layer forms areola; areola is set in the middle of steel inner cylinder layer and enamel flaggy; make areola form pressure-fired to beating compressed air in areola; the mode that makes its pressure be greater than the pressure of flue gas to board with enamel panel layer cannot penetrate in the seam of board with enamel panel layer and board with enamel panel layer flue gas and steam; effectively edge and the steel cylinder surface of guard shield, improved application life.
As preferably, the areola width of steel inner cylinder layer and the setting of liner enamel flaggy is 3-5cm.
As preferably, U-shaped stainless steel joint angle number of codes is identical with rectangle stainless steel square pipe holder quantity.
As preferably, rectangle stainless steel square pipe holder is fixedly connected on glassed steel flaggy by two stainless steel self tapping self-tapping screws, U-shaped stainless steel connects corner brace and is welded on steel inner cylinder layer, and the hole that rectangle stainless steel square pipe holder overlaps after being connected corner brace fit with U-shaped stainless steel is crossed connection by stainless steel to wearing connecting bolt coil.
As preferably, U-shaped stainless steel connects corner brace, stainless steel is 316 type stainless steels to wearing connecting bolt, stainless steel self tapping self-tapping screw and rectangle stainless steel square pipe holder, the utilization of this material, the application life of improving product.
In sum, the utility model is by utilizing the liner of enamel flaggy as inner wall of stack steel inner cylinder, utilize the performance of board with enamel panel layer to reach corrosion-resistant effect, joint treatment between board with enamel panel layer adopts between chimney wall steel inner cylinder layer and enamel flaggy, areola to be set and to squeeze into compressed-air actuated method and forms pressure-fired simultaneously, and utilize pressure differential to prevent that flue gas and steam from infiltrating the seam between board with enamel panel layer and board with enamel panel layer, reach the object on effective guard shield edge and steel cylinder surface, the utility model has improved the application life of Chimney in Fossil Power Plant, reduce costs, there is good economic and social profit.
