Abstract
The invention relates to a flue gas denitration reactor. An internal layer of a reactor shell is a wear-resisting layer (4); a heat-insulating layer (3) is coated outside the wear-resisting layer (4); the outside of the heat-insulating layer (3) is provided with a lateral plate (5), a top plate (2) and an inclined plate (6); the top plate (2) and the lateral plate (5) form a first opening (1) together on the upper part of the reactor shell; and the inclined plate (6) and the lateral plate (5) form a second opening (7) together on the lower part of the reactor shell. The flue gas denitration reactor is also provided with a heat-resisting steel bar (8) welded on the inner wall of the shell; the heat-insulating layer (3) is fixedly supported on the heat-resisting steel bar (8); the wear-resisting layer (4) is also fixedly supported on the heat-resisting steel bar (8); the heat-insulating layer of the wear-resisting layer is positioned on the inner side of the reactor shell, so that a stressed structure of the shell directly contacts external environment; and the shell is in a state of normal temperature, so that the denitration reactor has the advantages of small high-temperature creep deformation, high durable strength, high structural safety and low manufacturing cost.
Description
Technical field
The invention belongs to the technical field of denitrating flue gas device fabrication, relate to a kind of interior insulation selective catalytic reduction flue gas denitration reactor.
Background technology
The selective catalytic reduction gas denitrifying technology is that China uses the most general a kind of gas denitrifying technology at present, adopting in this technology denitrification process the most, the device of core is a flue gas denitration reactor, in flue gas denitration reactor, install catalyst, make nitrogen oxide and reducing agent reaction changing into nitrogen G﹠W in the flue gas.Because the flue-gas temperature of flue gas denitration reactor is higher, need take heat insulation measure to reactor.
The heat preserving mode that the selective catalytic reduction flue gas denitration reactor of correlation technique adopts is outer mode of laying heat-insulation layer.Flue gas denitration reactor comprise the housing 1 of steel ', be welded on housing 1 ' on reinforcing rib 3 ', be welded on reinforcing rib 3 ' on bar-mat reinforcement 2 ', be laid in bar-mat reinforcement 2 ' on heat-insulation layer 4 ' and be fixedly arranged on heat-insulation layer 4 ' on fixedly grooved band 5 ' and be installed in fixing grooved band 5 ' on contour plate 6 '.
Heat insulation between the flue gas denitration reactor of the outer insulation of this kind and the external environment has effect preferably, but insulation construction is comparatively complicated, and the metal material consumption is many, and the insulation cost is higher; Simultaneously because the housing of flue gas denitration reactor is a steel, it directly contacts with high-temperature flue gas, its creep rupture strength and creep strength performance all can have greatly changed, security meeting to the structural strength of flue gas denitration reactor produces bigger influence, for guaranteeing safety of structure, flue gas denitration reactor need adopt multiple structure strengthening measure, makes manufacturing cost rise.
Therefore be necessary above-mentioned Benitration reactor is improved in fact.
