Embodiment
To enable features described above of the present utility model and advantage to become apparent, special embodiment below, and coordinate appended
Figure is described in detail below.
The present embodiment provides a kind of novel rectifying device, in SCR denitration reactor as shown in Figure 1, the rectification to be filled
Put as shown in Figure 2 and Figure 3, its framework is made up of a square frame 21 with some longerons 22, crossbeam 23, square frame 21, longeron 22 and crossbeam 23
Using H profile steel, square frame 21 is divided into multiple square regions by longeron 22 and crossbeam 23, and a grid is provided with each square region
Unit 24.
The grid of traditional fairing is all directly welded on framework, and the present apparatus is realize grid detachable
Change, using special design, its side structure is as shown in Fig. 4, Fig. 6, and border circular areas is enlarged drawing in figure, is easy to show trickle knot
Structure.Grill unit 24 includes the uniform cowling panel 246 of multiple horizontal directions, the vertical space of formation, in grill unit 24
Left and right sides longitudinal edge be designed with a horizontal fixed plate 242 containing screw, bolt 25 is fixed on by the fixed plate 242
On square frame 21 and longeron 22；Two transverse edges up and down of grill unit 24 with bolt 25 without being fixed again, it is only necessary to is overlapped on
On crossbeam 23 and square frame 21.When a certain grill unit 24 is damaged, it is only necessary to turn on the just replaceable grid list of bolt 25
Member 24, it is not necessary to changed to whole device, changes convenient, time saving and energy saving, saves renewal cost.
Because whole framework is fixed in SCR denitration reactor, it will not generally change, therefore in order to protect longeron 22
Cause to damage from smoke-shock with crossbeam 23, covered respectively in longeron 22 and the top of crossbeam 23 and indulge wear strip 26 and horizontal wear strip
27, horizontal wear strip 27 is located at the vertical top of wear strip 26, as shown in Figure 8, Figure 9.Two wear strip structures are identical, including inverted V-shaped top plate
261st, 271, a vertical sole 262,272 is respectively connect on two pin of inverted V-shaped top plate 261,271, as shown in Figure 5, Figure 7.
Traditional wear strip is all welded on longeron and grid, when damage needs to change, it is necessary to using physics mode
(such as tap, cut) breaks pad, wastes time and energy, is very much trouble.To solve the problem, the wear strip of the present apparatus is using card
The mode connect is connected.Wherein, the connected mode of wear strip 26 is indulged as shown in figure 4, being welded on the horizontal fixed plate 242 of grill unit 24
A longitudinal baffle 243 is connect, the longitudinal baffle 243 and the longitudinal edge cowling panel 241 of grill unit 24 constitute a groove, the groove
Can clamping indulge a sole 262 of wear strip 26, realized in this way, vertical wear strip 26 is connected in two grooves by two soles 262
Connection, during replacing, all can directly be pulled down, simple and easy to do.The length of sole 262 can be set as needed, can be against bottom portion of groove.
The knuckle size of inverted V-shaped top plate 261 is determined according to actual, it is ensured that the height of vertical wear strip 26 is not higher than the height of grill unit 24
Degree.To ensure the gas permeability of the vertical two side areas of wear strip 26, multiple through holes, flue gas can be provided with longitudinal edge cowling panel 241
Both sides are flowed to by inverted V-shaped top plate 261, flowed out by through hole, less resistance and impact is realized.
Similarly, horizontal wear strip 27 connected mode as shown in fig. 6, grill unit 24 by transverse edge cowling panel 244 with
Lateral partitions 245 constitute a groove, and horizontal wear strip 27 is connected in groove by two sole 272 and realizes connection, during replacing,
All can directly it pull down, it is simple and easy to do.The length of sole 272 can be set as needed, can be against bottom portion of groove.Inverted V-shaped top plate 271
Knuckle α sizes determined according to actual, because horizontal wear strip 27 is located at the top of vertical wear strip 26, to ensure that height was unlikely to
High and flow of flue gas, α is 90 ° preferable.When flue gas comes, both sides are flowed to by inverted V-shaped top plate 271, then directly pass through grid
Flow through, reach the purpose of protection crossbeam 23.
It is noted that direction in length and breadth described in the utility model belongs to relative concept, it is convenient only to compose a piece of writing, and described is vertical
It is beam 22 and crossbeam 23, longitudinal edge cowling panel 241 and transverse edge cowling panel 244, longitudinal baffle 243 and lateral partitions 245, vertical
Wear strip 26 is similar each other to each vertically and horizontally modular construction of the horizontal grade of wear strip 27, only distinguishes before title titled with " vertical " " horizontal stroke ".
In a particular application, when only existing a kind of beam in direction, the beam is considered as longeron, and place direction is longitudinal direction；When two kinds of directions
Beam all in the presence of, regard beam that lower section wear strip (such as the vertical wear strip 26 in the lower section of horizontal wear strip 27) covered as longeron, place
Direction is longitudinal direction.It is also pointed out that, in above-described embodiment grill unit and framework be detachably connected be using bolt connection as
Example, but without limitation, in concrete application, also can using buckle, fasten etc. and to be detachably connected mode.
