The separating device comprises a support leg, an elastic sealing plate and a sealing bent plate, wherein the support leg is in an L-shape; the cross side of the support leg is lapped with the elastic sealing plate and then is fixed with a bolt; and the elastic sealing plate is movably lapped with the sealing bent plate. The elastic movable separating device for flue gas disclosed by the utility model can prevent denitrification flue gas from being cut out so as to ensure high denitrification efficiency; the separating device radically solves the problem of differential expansion between a denitrification reactor and the housing of a waste heat boiler; meanwhile, the separating device has a better sealing effect than a common separating plate; and besides, the separating device is convenient to install and replace, and only the elastic sealing plate needs to be replaced.
Description
Technical field
The utility model relates to a kind of flue gas baffling device, relates in particular to a kind of elasticity activity flue gas baffling device, belongs to the out of stock device technique of boiler smoke field.
Background technology
In the exhaust-heat boiler flue gas denitration, NOx reacts at catalyst surface with the ammonia that sprays in the flue gas, generates N
2And H
2O, therefore, needs assurance flue gas fully contacts with catalyst, and the flue gas short circuit phenomenon can not be arranged; In addition, waste heat boiler is generally internal insulation structure, be to have differential expansion between furnace shell and the Benitration reactor that is arranged in waste heat boiler inside, and, interior insulation guard board is the flakey mounting structure, if directly adopt steel plate with this insulation guard board and Benitration reactor clearance seal, and then can be because the thermal expansion of Benitration reactor causes this insulation guard board to come off in the running, cause immeasurable loss to safe operation of the boiler, also will affect denitration efficiency simultaneously.
In order to guarantee that Benitration reactor and waste heat boiler furnace shell gap can not have the flue gas circulation, guarantee denitration reaction efficient, this gap flue gas of must taking measures to intercept, if directly adopt the Plate Welding sealing, when hot operation, because Benitration reactor produces thermal expansion in the furnace high-temperature flue gas, and furnace shell is without expansion, then namely have differential expansion, this differential expansion can pull the furnace shell insulation guard board fall, and affects safe operation of the boiler.Therefore, need to consider that a kind of well sealing fume can solve again the brand-new device of differential expansion.
The utility model content
The purpose of this utility model is: a kind of elasticity activity flue gas baffling device is provided, effectively solves thermal expansion difference and flue gas short circuit sealing problem, and install and to change this structure extremely convenient, thereby can effectively solve above-mentioned problems of the prior art.
The purpose of this utility model is to realize by following technical proposals: a kind of elasticity activity flue gas baffling device, comprise supporting leg, elastic sealing strip and sealing bent plate, described supporting leg is inverted L-shaped, bolt is fixed after the horizontal edge of supporting leg and the elastic packing oblique cut grafting, elastic sealing strip and the movable overlap joint of sealing bent plate.
As a kind of optimal way, establish bolt hole on the horizontal edge of supporting leg, elastic sealing strip links to each other with supporting leg by bolt and nut.
As a kind of optimal way, the lap of splice is 30-40mm between described elastic sealing strip and the sealing bent plate.
As a kind of optimal way, the vertical edge of described supporting leg inserts in the furnace shell and with it welding.
As a kind of optimal way, described sealing bent plate and out of stock reactor are fixed.
Compared with prior art, the beneficial effects of the utility model: the utility model elasticity activity flue gas baffling device can prevent the short circuit of denitration flue gas, guarantee high denitration efficiency; Thoroughly solved the differential expansion problem between Benitration reactor and the waste heat boiler furnace shell, the more common baffler better effects if of while sealing effectiveness, and, install and change conveniently, only need to change elastic sealing strip and get final product.

Fig. 1 is the structural representation of the utility model elasticity activity flue gas baffling device.
Among the figure: the 1-supporting leg, the 2-elastic sealing strip, 3-seals bent plate, 4-bolt and nut, 5-bolt hole, the out of stock reactor of 6-, 7-furnace shell, 8-heat-insulation layer.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Disclosed all features in this specification, or the step in disclosed all methods or the process, except the speciality and/or step of mutual repulsion, all can make up by any way, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose, namely, unless special narration, an embodiment in a series of equivalences of each feature or the similar characteristics.
As shown in Figure 1, the utility model elasticity activity flue gas baffling device comprises supporting leg 1, elastic sealing strip 2 and sealing bent plate 3, and described supporting leg 1 is inverted L-shaped, and the inverted L-shaped at this place is for to be comprised of a vertical edge and a horizontal edge, and horizontal edge places the upper end.The vertical edge of described supporting leg 1 inserts in the furnace shell 7 and with it welding, and this limit and furnace shell form the uniformity of integral heat insulation, are provided with heat-insulation layer 8 in the described furnace shell.Bolt is fixed behind the horizontal edge of supporting leg 1 and elastic sealing strip 2 overlap joints, specifically, establish bolt hole 5 on the horizontal edge of supporting leg 1, elastic sealing strip 2 links to each other with supporting leg 1 by bolt and nut 4, elastic sealing strip 2 and sealing bent plate 3 movable overlap joints, both can be freely movable when hot; The lap of splice is 30-40mm between described elastic sealing strip 2 and the sealing bent plate 3, and is best when the lap of splice is 30mm; Described sealing bent plate 3 is fixed with out of stock reactor 6.
Embodiment 1:
This elasticity activity flue gas baffling device mainly is comprised of supporting leg 1, elastic packing plate 2, sealing bent plate 3 and bolt and nut 4, and installation can be divided into three parts and carry out: supporting leg is installed, the sealing bent plate is installed and elastic sealing strip is installed.
Wherein, supporting leg select wide for 400mm, thickly form for the steel plate bending of 6mm, the vertical edge of supporting leg is long limit, its length is according to the insulation layer thickness adjustment, generally for the ease of installing, long limit is incubated the large 100mm of bed thickness and is advisable, the long limit of supporting leg and furnace shell welding and with the furnace shell integral heat insulation, the horizontal edge of supporting leg is minor face, opens on request bolt hole on it.
